continuing PLIP problems

Post by Carl Tichl » Thu, 25 Jan 1996 04:00:00



As an update to my continuing attempts to get PLIP working:

I was successful in getting PLIP working on my Micron machine
at home, connecting to my AMD laptop.  No special options ifconfig --
plip0 for the Micron, plip1 for the laptop.  

However, when trying to connect to the Compaq Deskpro 50
at work, ifconfig plip0 defaults to IRQ 5, hardware address
0x3bc.  But running diagnositics in MS-DOS ("MSD") shows the
IRQ as 7.  I tried overriding the IRQ by running:

ifconfig plip0 192.168.1.3 pointopoint 192.168.1.1 -arp irq 07

But I get the message:

SIOCSIFMAP: Device or resource busy.

Any pointers on this?

Thanks (again) in advance,

Carl Tichler

NOTE:  All machines are running kernel version 1.2.13.  I also
had to get an updated NetKit to get the version of ifconfig which
displays the IRQ and hardware address.

I have no experience with PLIP but I have had all sorts of complications with
printers and parrallel-port Tape backups on Compaq machines.

It seems that the Compaq LPT ports are non-standrd in some way.
I have got the above to work by setting things to only expect uni-directional
and to have maximum delays (ie slow transfer) and the most basic and
failsafe handshaking.

Sorry I cant give specific advice , but keep in mind that the LPT port is
not what it may seem to MSD or the PLIP driver.

1. PLIP problems continue

I continue to suffer from nasty PLIP problems.  Noticing these problems now
extending into UDP stuff.

Is the retry/recover-from-dropped-packets function broken in .89?  

PLIP reports timeouts to the syslogd that applications running across it
(Telnet, ftp, and now NFS) aren't recovering from.

Even though the links managed by these services die, the actual PLIP
connection remains viable for pinging and establishing new links.
Unfortunately, the new services eventually die given enough timeouts.  NFS
is much less likely to die but when it does, it always seems to do it when
it's most needed, like during a backup :(

Do you slip users lose your telnet or ftp links if you grunge the SLIP cable
for a few seconds?  (It's hard to test this, killing CD or DSR tends to
remove slip ifconfig entry completely.  This isn't the problem I'm seeing as
the plip_ device remains in ifconfig and continues to respond after the
transported service dies)

Kernel version 1.1.89, net tools 1.1.79, modules 1.1.87.  My cable is 1.5
meters long, problems with all sorts of parallel cards, no conflicting
interrupts, etc.
