I find the Sun Network Programming manual (Sun OS 4.1.2) very useful for 
STREAMS programming.

Subject:   LAN 8bit

I like to have an 8 bit connection on the remote login (abount telnetd).
The LAN is from Lachman. The Terminal-emulation on my PC can work
in 7-bit or 8-bit mode. But the System (SCO Unix) gives only an 
7-bit connection. Where can I change this?

Subject:   Mixed trafic - x.25/TCP/IP

Hi - and Happy New Year,

We are considering a new network which connect all of our different
sites through a WAN. We will probably buy some CISCO routers. 

The trafic which is routed through the CISCO equipment is split
in two

       - FTAM trafic based on x25 connections             
    
       - Interactive terminal sessions based on TCP/IP on an Ethernet.


The CISCO routers can mix these two kinds of input intp one 2Mbit channel
which connects the different sites.

My concern is now : Will the interactive traffic suffer when a heavy
FTAM transport is taking place ?. Will the file transfers affect the
responsetimes for the interactive traffic to a large extend ?.

Is you have any experience with this please E-mail (or fax) me the 
information

It may well also annoy people who don't want the application to give up

Subject:   Trouble configuring UUCP on TCP/IP

A piece of information that I forgot to provide:  I had to change
the entry in /etc/inetd.conf for uucpd from "/etc/uucpd" to
"/usr/lib/uucp/uucpd" in order to get to the password prompt.  I
just changed the entry back to "/etc/uucpd" in both system's
files and got the following:

mchFind called (McDonal)

Notice the "user unknown" above?  I was getting this when there
used to be a password on the account, before the password was
even prompted for!  Now I have removed the password because of
some recent postings about two Sun systems needing the parity
changed for the password.  Since this is a TCP connection, the
password is not necessary, so I've removed it.

I don't know why there are two "uucpd" programs, one in "/etc"
and the other in "/usr/lib/uucp", but using the one in uucp does
not produce the "user unknown" message.  I think that there is
some TCP configuration info either missing or incorrect so that a
UUCP connection attempt bombs this way.

This is new territory for me so I'm just guessing at what could
be wrong.  The documentation does not cover setting up UUCP on
TCP/IP very well at all.

Thanks for any help you may be able to provide.

Subject:   Announcement: CSLIP for SunOS 4.1.x

A revamped SL/IP package for SunOS 4.1.x is available for
anonymous ftp from dmssyd.syd.dms.csiro.au, under
the file src/cslip-sunos.tar.Z

Kam Tam from the CSIRO has kindly allowed me to place the
package on dmssyd, as we do not have a direct Internet
connection. Any comments, complaints or corrections should
*not* be directed to anyone at the CSIRO, but to
me (andrew@mega.oz.au).

I have seen several people asking about cslip for 4.1.x, and
I have sent a few people this package and they tell me it works,
and that I should make it publicly available, so here it is.

The first origins of the software is lost in the mists of time;
Mark Andrews (from CSIRO) converted it to use SunOS STREAMS.
I used that package as a base, and have hacked it mercilessly to
add VJ TCP header compression, and to streamline it so that it can
run a little faster.

It has been tested and used on IPC's, SS1's and some other
Suns we have lying around, all under SunOS 4.1.1 - I don't
see any reason why it wouldn't drop into any 4.1.x system,
but your mileage may vary.

The primary motivation for doing this was to get TCP
header compression running on low speed (2400 baud) SL/IP
lines - PPP could not be used because the terminal servers
on the other end can't talk PPP. Even if you do not
use header compress, it is probably worth using this
package for ordinary SL/IP because of the CPU cycles you
will save.

Please send any comments, patches etc. to me. It would help
if someone compiled it and ran it on 4.1.3 just to see
if it works.

The README is attached.

Enjoy!

------------------
README for SunOS 4.1.1 Compressed SL/IP

The original package was developed by Mark Andrews @ CSIRO DMS Sydney,
from the original SL/IP stuff.

This version has been much modified, with the dual goal of adding
Van Jacobsen's TCP header compression, and improved performance.
Even if you do not use the header compression stuff, the reduced
load on the CPU is worth it.
It should be completely compatible with old SL/IP drivers, as
the TCP header compression can be enabled/allowed via an option
to slip-attach.

A summary of changes:

- Added TCP header compression - The standard header compression code
  was used unmodified *except* for a small mod to use mbufs in the
  decompression so that the caller would not have to allocate 128 bytes
  at the start of every packet. The new slcompress.c is included.

- Collapsed the SL/IP frame encoding from a separate STREAMS module
  into the main module. An attempt to reduce extra overhead.

- Removed re-copies of data. As a result of having two STREAMS modules
  in the stack, the same data was copied to and fro several times.

- Attempted to guess some buffer sizes to avoid scanning the whole
  packet and count the ESCaped characters.

- Added the FLAGS setting code, and also put in the slip stats
  counting.

By far and away the biggest difference in performance is due to the
(almost paranoid :-) avoidance of data copying. In the old code I
counted 4 copies of the same data; 1) from zs driver to STREAMS mblk,
2) in slipencode, from STREAMS mblk to internal buffer, 3) at end
of packet to another mblk for xfer to str_ip, 4) in str_ip from
the mblk to the mbufs. On output the code scanned the entire packet
and counted the escapes before allocating a mblk, then had to
scan the packet again to copy it.

The new code copies the mblk data from the zs driver directly to mbufs,
after doing the SL/IP frame decoding.
On output a buffer is allocated after a scratch-the-head fudge
factor is added to the actual length of the packet, and then the
packet is copied. If it runs out of room, it retries with a bigger
packet etc. I keep a track of the number of recopies, and it has
never needed to do one yet, so I figure it's a win.

The SunOS 4.1.1 serial driver for the Zilog 8530 (at least on
all the Suns I have tried) is still a performance black hole, but
at least the rest has been leaned down somewhat. It does make
a difference. The problem seems to be related to extra interrupts
and CPU load when the SL/IP is busy. For example, in one test I
sent large ping packets to an idle workstation on a 19.2 Kbaud
SL/IP line; the system time went to over 50%, and the number of
interrupts went to over 27000 per second (I would only expect around
4000 max), so if *anybody* knows what's going on and can give
me a magic fix, I would appreciate it.

Installation Instructions.
--------------------------
cp slip_var.h slcompress.h /usr/include/sys
cp slip_var.h slcompress.h /sys/sys
cp streamsip.c slcompress.c /sys/os

edit /sys/conf.common/files.cmn and add the lines:

os/streamsip.c                optional slip
os/slcompress.c               optional slip


edit /sys/sun/str_conf.c and add:

#include "slip.h"

#if     NSLIP > 0
extern  struct  streamtab streams_ip;
#endif

#if     NSLIP > 0
	{ "str_ip", &streams_ip },
#endif

Edit your kernel configuration /sys/sun?/conf/MACHINE and add the
line below to install the SL/IP psuedo devices.

pseudo-device    slip2

Build the new kernel, install and reboot.

make and install slip-attach and slipstat

run slip-attach
	slip-attach [ -csa] device speed local remote netmask

Where -c will turn on header compression, -a will only turn it on
if a valid compressed SL/IP packet is received. The default is
to disable the header compression. -s will set a small MTU (256 bytes);
the default is 1006 bytes.
e.g.
/usr/local/etc/slip-attach -c /dev/ttya 19200 my_host their_host 255.255.255.0

slipstat will give you statistics about normal and compressed packets sent
and received. Run it with stdin set to the device that the SL/IP module
is running on e.g.

	slipstat < /dev/ttya

Slipstat has an option (-c) to print the header compression stats, and
you can also put a delay and count in to continuously print the stats e.g:

	slipstat -c 10 5000 < /dev/ttya

will print the header compression stats every 10 seconds for 5000 samples.

Enjoy!

We've been having some problems lately with services getting CLOSED out.
When this happens, you can do a netstat and it will show telnet, for
example, as being in a "CLOSED" state.  No one can telnet in because it
did not do a passive open.  What could be causing this?  When I kill the
offending telnet process, it clears up the problem.  But I'd like to
know what is causing it in the first place so I can correct it.  Any
ideas?

Actually, this was the uutry log produced after I changed the
entry in "/etc/inetd.conf" from "/etc/uucpd" to
"/usr/lib/uucp/uucpd".  There seemed to be another uucpd on the
system and it seemed to get me a little further along in the
dialogue.  The original uucpd was producing a "user unknown"
message right after the login name was given and before a
password was even checked.  This is the right uucpd to use, which
was pointed out to me by belal@sco.com.  The one in usr/lib/uucp
was released with the UNIX runtime in error and was compiled from
an earlier version of the source, with the wrong development
environment.

The mystery is solved.  It seems that the Systems file entry chat
script that was used when a modem was being used to connect was
producing my "user unknown" message.  Here are the two entries
that I have used to fix the problem:

#SystemB Any TCP,e  Any - --gin:--gin:--gin:-BREAK-ogin:-BREAK-ogin: systema word: foobar
SystemB Any TCP,e  Any - gin: systema word: foobar

The first one was being used until today, when I was mailed an
extract from the SCO "How to" database that showed the greatly
simplified chat script.  I decided to take a shot in the dark and
see if the BREAK (which I never saw being sent in the uutry log)
was causing the trouble.  The second entry worked fine, first
try.

I am now going to test the first entry by just removing the BREAK
portion of the entry, to see if it is the syntax of the script
that causes the problem, or the BREAK.

    a) If the TCP/IP-software in my PC is the Wollongong WINTCP for DOS
       there is no trouble in connecting the PC (with telnet) to the 4D/20G
       type IRIS with the older IRIX 3.3.1 operating system,
       but it cannot be connected to the other IRIS (with IRIS 4.0.5)?
    
    b) If I am using a product called PCTCP instead of the WINTCP I can
       connect to both IRIS workstations with no trouble.
    
    This started when we took the newest release 4.0.5 of IRIX! Before that I
    could connect the PC to both workstations with WINTCP.
    
    We have checked what happens on the lines. The messages seem to go to the
    IRIS quite OK but the messages it sends to the PC are not understood by
    the WINTCP and everything just stops.

It isn't really clear from this what the problem is:  Does ARP fail (you
should be able to check the cache on both ends), or is it that ARP works
but TCP can't make a connection?  Or is the problem that the TCP connection
opens but you never get a Telnet prompt?

If ARP fails, then the issue may be in the PC's hardware driver - you don't
say which network interface you're using, but the TWG driver may not go to
as much effort to salvage packets in the face of board errors.

If TCP won't connect, examine the packets and refer to RFC 793.

If Telnet never gets a prompt, the issue might be in Telnet option
negotiation.  Check the Assigned Numbers RFC for the names of the options
that Irix is asking for, and check how the PC responds to each.

Subject:   BOOTP and the first stage bootstrap

Is there a configuration option in bootp that will allow a
client to get a bootp request from one machine and the first
stage bootstrap from another machine.  We had the impression
that this is possible but I cannot find out how to accomplish this.
We have multiple subnets and are willing to put a bootp server
on each of the subnets. We would like the clients to boot off
of a different machine than the bootp server.

Thanks for any help.

This seems to be an ugly part of the BOOTP protocol.  If you look in section
7.3 of RFC 951, the client is expected to use the siaddr field as the TFTP
server's IP address and sname as the name.  I would think it would be safe to
set siaddr and sname to something other than the BOOTP server's address.
Why would the client want the BOOTP server's address?  What it really needs
is the TFTP (or other boot protocol) boot address.

I'm sure this will be a controversial suggestion, but I think it's justified.
It satisfies the use of the siaddr (and sname) fields, if not the intent.
If it really bothers you, think of it as "proxy BOOTP".  ;-)

Oops!  I forgot to mention that your client will have to use the RFC 1084
vendor extensions, or a similar vendor extensions field, in order to give
the client its netmask and gateway.  You can't TFTP through a gateway
without that info.

	A little insight/info would really be appreciated!!

1) I need to write an application that services users who dail-up via a terminal
server and are rlogin'ed or telnet'ed to a specified host.  Is there any easy way
from a 'C' application to determine the pty?

2) Since TCP/IP is the underlying transport, does using pty's cause significant
additional overhead?  Is there a straightforward method of accessing the socket,
and doing socket level communication between the process and the terminal server?

Thanks in advance!!!!!!

Subject:   STARLAN 10 10BASE-T hub unit doesn't like adapters

I have two somewhat old (circa 1988) STARLAN 10 hub units that 
are part of our TCP/IP ethernet LAN. Our lab is wired twisted pair
with RJ-45 plugs. This is fine for our PCs with their RJ-45 port 
cards, but for our UNIX boxes (Suns), we need to use AUI to RJ-45
adapter boxes.

Here's the problem. We recently bought a new (1991) adapter box from
Cabletron, but it did not work when we wired it up. We have a few 
old adapters from AT&T (which came with our now defunct 3B2s (ick!)),
and some others from a company called David Systems, which work A-OK.

I am somewhat perplexed. Has there been a change in the 802.3 standard,
are our hub units no longer usuable, or am I just missing something
somewhere ?? It would seem a shame to throw out 22 usuable ports, 
especially with the price of some of the new fancy-pants hubs I've
been looking at.

I apologize if these are newbie questions, or are more appropriate to
another, more wire-head hardware group.

Subject:   WINTCP or DOS / IRIS Problem.

Hi folks,
Last week I posted an explanation about a problem with the
Wollongong WINTCP for DOS TCP/IT connection to IRIS workstation.

I received two mail answers and one posting to this newgroup.
Shantanu Kothavale from the Wollongong Group answered that there
is something in the WINTCP which makes it do this. It had something to
do with the large window sizes.
Tom Mitchell from Silicon Graphics responded also and he said that
the large window size of 60k in the new release of IRIX is the cause and
that we should alter it as the parameter fortunately is external (the
value in earlier release is 24k). The same has happened with several
other products than WINTCP too.

We did it and now it seems to work again.  Thank you very much!

This just makes us wonder. Why has the window size been changed? What
do we lose changing it back to its original value, 24k?

I have done exactly this.  The only "trick" is that the CMU bootpd server
checks to see if the download file is on the system.  When the new "sa"
(server address) tag is used in the bootptab file it doesn't check for the
file -- I didn't want to try to verify that the file existed on the remote
system.  I've sent this modification to CMU but I haven't seen it come back
out.

Also, as noted in a later post, you need to send the gateway and subnet
mask if you're booting through a gateway.  

Another useful modification I made was to be able to use host names instead
of IP addresses for the "ip" tag.  I hate duplicating information already
in the hosts file.

Reminds me of some sort of Telnet option negotiation loop or deadlock. Your 
telnet program may be responding WILL to some option but may not be 
properly doing so. Something like this may cause the other system to wait
indefinitely. The other possibility is the two pairs are entering to
an WILL/DO or DON'T/WONT kind of negotiation loop. I don't know how PC-NFS
telnet debugging feature works, but depending on the implementation, I 
think you may not be able to see anything on the trace if a loop occurs.

The main difference between StarLan10 and 10baseT is that 10bT requires

to disable LinkBeat on all devices on the network.

Hi,
  This seems like a good book:

Distributed systems / edited by Sape Mullender.
New York, N.Y. : ACM Press ; Wokingham, England ; Reading, Mass. :
          Addison-Wesley Pub. Co., c1989.

I had a bit of a read of it to get a basic idea of distributed systems.

many thanks to all those people who replied to my last post, when i asked how
would i perform the equivalent of a remote "netstat -rn" on 
arbitrary internet hosts.

Most people suggested SNMP. However, wouldn't this limit me to
querying hosts running SNMP? 

I was hoping that there would be a solution which only required 
that the gateway in question be running some routing daemon
talking RIP (e.g. gated), which is a more common property of gateways
than SNMP .

I vaguely remember hearing of a program called ripquery, but i can't
find any info on it. Has anyone heard of such a thing ; would this
do the job I just described in the previous paragraph?

There is `rtquery` source in the standard 4.3BSD distribution (I think
in the tools subdirectory of the routed subdirectory), and binary
shipped on some (at least one--guess which) vendors' workstations.

Rtquery works by sending out mostly ordinary RIP requests.
It obviously doesn't work if you are not using RIP.
It also does not work if the remote machine is picky, as cisco routers
seem to be.

ripquery is a program which comes with gated. But it does not show
the routing table of a gateway, it only show which rip routes the
gateway is advertising.

Using only RIP may not give you all of the information you want.  You can
certainly send a RIP Request to a remote machine. But, the only information RIP
will send back is a list of destinations for which that machine has routes, and
the associated metrics.  For example, it will not tell you what gateway the
remote machine uses to reach the destination.  Nor will you get any of the
other information which netstat provides.

Subject:   Help! (75 seconds to connect() after reboot)

Help!  I've found a situation in which I'm unsure of the best 
solution.  The problem has to do with a 75 second timeout in the 
connect() system call.  This occurs after one of two previously
connected machines is rebooted and an attempt is subsequently
made to reestablish communication.

I am using TCP/IP via Berkeley sockets to communicate between a Sun
workstation and an embedded system running VxWorks.  After communi-
cation is established, the embedded system is rebooted.  Once the
reboot is finished an attempt is made to reestablish the connection,
at which point, the connect() system call on the embedded system is
unable to reconnect and times out after 75 seconds.  

I believe this may happen because the embedded system is using the 
same port number that was used for a connection before the reboot 
occured (while the remote machine still maintains an established 
connection on that port).  It appears that (after a reboot) if the 
embedded system attempts to connect() using a port number which was
not previously connected, the connection is immediately established; 
this is the desired behavior.  However, if the embedded system uses 
a port which was previously connected, the connect() system call 
times out after 75 seconds.

Unfortunately, in my application 75 seconds is somewhat too long 
to wait.  I have a potential work around, but it seems to be
sort of a kludge and I felt certain that this problem must be a 
known one with known solutions.  (I'm relatively new to NEWS and if
this is a topic which has already been discussed in depth or I have
improperly used this service in any way, I appologize.)  But if 
someone with insight into this problem would enlighten me on the 
issues involved, or documentation to be studied, or potential 
solutions, I would greatly appreciate the help.

Careful: ripquery is not to be trusted, precisely because it does *not* 
truthfully show the routes that are being rip-advertised.  ripquery operates 
by generating a rip POLL, which explicitly asks the queried gateway to say 
what its rip-list looks like.  Unfortunately, most machines ignore 
split-horizons when they respond to a rip POLL, so what you'll see is a 
list of *all* the advertisements that gateway is making, regardless of whether 
or not it will make them onto the network that you're querying over.

The only way to really make sure of what advertisements a gateway makes is
to sit and listen for them, e.g. with gated tracing turned on or some
handmade NIT utility.

in vxworks 5.0+, there is an undocumented call -- connectWithTimeout() which
takes the same args as connect() plus extra last arg of type 'struct timeval *'
which you may be able to use -- you can specify the delay of your own.

or you could also just try non-blocking connect() -- set socket FIONBIO
temporarily, call connect(), which should return EINPROGRESS immediately
if connect attempt is to block -- when this happens you should select()
for 'write'.  the socket will be marked writeable once's it's connected.
to verify the connection after select() returns with 'write' selected, you
can do a getpeername().  this is actually what connectWithTimeout() does.
[ i do hope this is still in vxworks, it was a few years back when i put this
into the system ]

When I use Kermit (3.11 or 3.12) to connect to a SCO/Unix system with

details:

1) I can't send a DEL to interupt a process. If I hit the DEL key

2) If I hit ESC, the connection hangs.

We use the same setup we use when connecting to TCP/IP 1.1.3 systems

TCP/IP 1.2 box to another, telnet just runs fine, including interpretation
of a DEL character.

Subject:   Why would a Sun take 1.5 seconds to retransmit a missed packet?

I am examing some data collected from a medical network, and noticed
some unusual timings.

A Sun is transmitting large files (3.5Mbytes average) to an archive 
system while receiving images from a scanner.

Packets are missed by the archive system, so the Sun has to retransmit
the missed packets. I have noticed large delays (0.5 - 1.5 seconds)
while the sending machine has to "back up" and retransmit packets that
were previously sent but never acknowledged. 35% of the sessions had
inter-packet delays > 1 second.  The receiving buffer size is 24K.

Why would there be such a long delay? I would expect the data is in
mbufs, so the time to resent the missed packets should be small. 
From the timing it looks like the data was occasionally on a disk.
If we wanted to remove these conditions, am I correct in assuming the
sending system needs more RAM or perhaps more buffers?

Subject:   Netblazer

I currently attach via SLIP over a leased line using v.32bis/v.42bis
modems from a Dell machine (on my end) into a smartport on a Telebit Netblazer.

Would I see any significant increase in throughput using this same
physical connection (v.32bis/v.42bis) but replacing the Dell SLIP
with a Netblazer on my end -- and connecting my machines via ethernet
to the Netblazer?

I assume this would give me the ability to support PPP/CSLIP since
my connection would be Netblazer-Netblazer -- what would PPP buy me
over traditional SLIP (our feed is basically for smtp/nntp traffic,
with ftps,telnets,rlogins used infrequently)..

You should take a look at RFC959. As well as providing a description of
the FTP protocol it describes the reurn codes in a fair amount of
detail.

I have a feeling that there is an RFC that describes the return codes
only but I can't remember which one.

>What is wrong with telnet?

Good question ! I also have trouble using PC-NFS Telnet...

I recently upgraded my PC-NFS 2.0 to a newer 4.0 version.
Unfortunately, I discovered that Telnet 4.0 is far slower than the older one.
Some pointers in the news enabled me to get the 4.0a patch, but Telnet is
still worse than before.

The machine is a Dell 316SX with 4Mb of RAM, with a 3COM 3C501 Ethernet
adapter.
The hosts are Sun's (4/330, SunOs 4.1.1) and HP's (9000-800, HPUX 8.0).

Note that the hardware did not change from 2.0 to 4.0 .

Telnet is particularly slow when I'm using the vi editor and scrolling into a
file (with the Ctrl-F "page forward" sequence) : sometimes I must wait several
seconds (typically 2 or 3) before the screen is updated.
With Telnet 2.0, the reaction was always immediate.

Knowing that Telnet 4.0 is a brand new implementation, I tried to use the
old one on 4.0 sublayers, but it didn't give good results.

Did somebody experience the problem ?
RTFM did not lead me to a solution.

Denis.

Subject:   TCP/IP & SNA on IBM Lan adaptor card, availability of virtual term?

Hi, I'm posting this for a friend, Please reply to
alen@crash.cts.com or post here (where he will look).

Alen's request for information...
I have a bunch of 486s running OS/2 connected via an IBM Token Ring
(using a LAN Adaptor card in each). The main node in this net will
be connected to a central machine (via ethernet and TCP/IP). I need
to access terminal sessions on the central machine from any of the 486s.
The central machine is likely to be a VAX w/VMS but may turn out (in some
cases) to be an IBM connected via SNA (LU6.2 capable).

Given these 2 scenarios, can anyone out there in NetLand advise me where
to look for bridging software across the OS/2 (NetBios) -> TCP/IP
VAX and across OS/2 (NetBios) -> SNA?

What kind of hardware requirements are there?

The main interest is in getting live terminal sessions from OS/2
PM windows on each PC node. There is some need for file and/or data
transfer, so leaving these options open would be a plus.

Thanks in advance

No I don't think you would get a significant performance increase by
putting a NetBlazer at both ends.  You are using relatively slow
serial lines limited by V.32bis modulation with whatever compression
you get with V.42bis.

You would get significant performance increase for telnet sessions
using TCP header compression.  This won't help UDP traffic of course.
This compression can be used with SLIP (CSLIP) or PPP.  Many PPP
implementations include header compression.

The main benefits of PPP are dynamic configurability and the ability
to run multiple protocols.  PPP negotiates things like header
compression, MRU/MTU size while trying to bring the link up.  With
SLIP all this must be statically configured ahead of time.

PPP has specifications for protocols other than IP.  People run IPX,
AppleTalk, XNS, Decnet, OSI, and bridging over PPP links.  SLIP is
only useful for IP.

Austin,
	Check out rfc640.. I believe that this is the latest source of 
information on this topic.. it is readily available from nic.ddn.mil in the
RFC sub-directory..

-Larry.


---Excerpt from RFC640 showing response codes for FTP---

       There are four values for the first digit of the reply code:      11a

       1yz   Positive Preliminary reply                                  11b

          The requested action is being initiated; expect another
          reply before proceeding with a new command.  (The
          user-process sending another command before the  completion
          reply would be in violation of protocol; but server-FTP
          processes should queue any commands that arrive while a
          preceeding command is in progress.)  This type of reply can
          be used to indicate that the command was accepted and the
          user-process may now pay attention to the data connections,
          for implementations where simultaneous monitoring is
          difficult.                                                    11b1

       2yz   Positive Completion reply                                   11c

          The requested action has been successfully completed.  A
          new request may be initiated.                                 11c1

       3yz   Positive Intermediate reply                                 11d

          The command has been accepted, but the requested action is
          being held in abeyance, pending receipt of further
          information.  The user should send another command
          specifying this information.  This reply is used in command
          sequence groups.                                              11d1

       4yz   Transient Negative Completion reply                         11e

          The command was not accepted and the requested action did
          not take place, but the error condition is temporary and
          the action may be requested again.  The user should return
          to the beginning of the command sequence, if any.  It is
          difficult to assign a meaning to "transient", particularly
          when two distinct sites (Server and User-processes) have to
          agree on the interpretation.  Each reply in the 4yz
          category might have a slightly different time value, but
          the intent is that the user-process is encouraged to try
          again.  A rule of thumb in determining if a reply fits into
          the 4yz or the 5yz (Permanent Negative) category is that
          replies are 4yz if the commands can be repeated without any
          change in command form or in properties of the User or
          Server (e.g. the command is spelled the same with the same

    NWG/RFC# 640                               JBP NJN 5-JUN-74 16:07  30843

          arguments used; the user does not change his file access or
          user name; the server does not put up a new
          implementation.)                                              11e1

       5yz   Permanent Negative Completion reply                         11f

          The command was not accepted and the requested action did
          not take place.  The User-process is discouraged from
          repeating the exact request (in the same sequence).  Even
          some "permanent" error conditions can be corrected, so the
          human user may want to direct his User-process to
          reinitiate the command sequence by direct action at some
          point in the future (e.g. after the spelling has been
          changed, or the user has altered his directory status.)       11f1

       The following function groupings are encoded in the second
       digit:                                                            11g

                  syntactically correct  commands that don't fit any
                  functional category, unimplemented or superfluous
                  commands.                                             11g1

          x1z   Information -  These are replies to requests for
                  information, such as status or help.                  11g2

          x2z   Connections - Replies referring to the TELNET and
                  data connections.                                     11g3

          x3z   Authentication and accounting - Replies for the logon
                  process and accounting procedures.                    11g4

          x4z   Unspecified as yet                                      11g5

          x5z   File system - These replies indicate the status of
                  the Server file system vis-a-vis the requested
                  transfer or other file system action.                 11g6

       The third digit gives a finer gradation of meaning in each of
       the function categories, specified by the second digit.  The
       list of replies below will illustrate this.  Note that the
       text associated with each reply is suggestive, rather than
       mandatory, and may even change according to the command with
       which it is associated.  The reply codes, on the other hand,
       should strictly follow the specifications in the last section;
       that is, Server implementations should not invent new codes
       for situations that are only slightly different from the ones
       described here, but rather should adapt codes already defined.

  If this is FTP, you'd probably be better off getting rid of the
  fatal collisions on the net.....unless you can set the time-outs
  to a very small number (very dangerous, but....)

try pulling the case off and seeing of the UARTs are 16550's.

Is there a PCROute driver, or a packet driver, which can talk to a PC

Subject:   SLIP on a SUN?

Hello,
    I need to put SLIP up on a SUN IPC running 4.1.2. Is there a general
    concensus as to which version is "best". I'm anticipating putting up
    cslip-2.6. Is this good, bad, or indifferent. Also, I keep reading in
    most documents associated with the various SLIP verions not to have
    a getty on the serial line. I'm confused. What I want to do is:

    1) Hang a getty on the receiving modem's port.
    2) Make the connection over a phone line.
    3) Login to a account that runs sliplogin or the equivalent.
       (I don't have sanction to run slattach on the host machine)

    Is this the general process? Is there a FAQ for SLIP installations?
    The best thing I've found so far is the O'Rielly TCP/IP Administration
    book's description. Are there any other "standard" references?

Thanks in advance,
Boyd Hays

I've had a similar problem.  When I used the Allied Telesis thick-10BASE-T
adapter and plucked the twisted pair into an AT&T STARLAN 10 hub, the
whole network starting dying with heavy collisions (and no traffic!).
WHen I replaced the hub with an Allied hub (more modern), no problems.
I thought STARLAN10 was supposed to be compatible with 10-BASE-T, but perhaps
there are some subtel differences which prevent this interoperation?

Subject:   How to network printers?


Hi netlanders,

I don't know whether this is right place to ask this question.  But, anyway,...

Our group has more than 10 PCs, one Dataproducts LZR-1260 b/w laser printer,
one HP Deskjet 500C color printer and one HP Scanjet IIp b/w scaner.
At moment, the printers and scanner are not networked, even though our
PCs are networked through ethnet to a Unix server.

We now want our printers and scanner to be networked as well.  What do we need?
Hardware, software?  Someone mentioned FASTPORT (TCP/IP network print server)
by MiLAN Technology should be OK for our purpose.  Is that right?
Any other options?

Your help would be greatly appreciated.

Please send responses to my account since I don't read this newsgroup very often.

I will post a summary if there are enough responses and interests.

Thanks in advance.

ka9q has had support for the 550 for some time.

i once asked Phil Karn if the rumor was true that the Netblazer kernel
was based on ka9q.

his responded something like "a much mutated version".

if the motherboard has 550's on it, it would be rediculous(sp?) for
telebit not to support them, especialy if the support was in the
base code.

       Those are pretty typical numbers for TCP layer time-outs...

If so, it indicates that 1) the path is long, 2) the archive system is very
slow or 3) the sending TCP has an inferior or broken adaptive retransmit
algorithm.  TCP should retransmit in something on the order of twice the
average Round Trip Time (from send to ack).  Some implementations use exactly
2X, others combine the RTT and its standard deviation.  With the TCP in PC/TCP
for DOS on a local LAN, the retransmit timeout is typically near its floor of
166 Ms, and I don't see any significant number of unwarranted retransmits.

Subject:   FTP ABOR vs data channel reset?

Hello Net

I would value information on ways to abort or terminate an FTP sessions
data channel.  According to the spec the suggested (required?) way is to
issue an ABOR command on the control channel. However I haven't yet found
any type of machine that takes any notice of this.  They all seem to finsh
the transmission and then say something like ABOR command successful.
Obviously this is kinda pointless - or am I just doing it wrong some how.

The other method is to reset the data channel. This works just fine but some
machines (SRV? unix) also shut the control channel (hence logging you out) at
the same time. This is kinda annoying.

So can anybody tell me if they have observed this as well - ( my software is
home grown so I can't really be too sure it isn't my fault). Any suggestions on
alternate methods?, anyone know of any catastrophic problems with the reset 
method (besides the one mentioned?). 

All info appreciated.
