Currently in want to install Slackware Linux version 3.3.0 based around
the 2.0.30 Linux kernel on an old 468DX2 computer using NFS. My server
is a Linux machine running on Suse 8.2 (kernel 2.4.20). The situation
now is that I only can install the boot and root-floppy and can run setup.

The problem that I encounter is that the connection is poor, sometimes
contact and sometimes not. Also ping gives a lot of package loss (from
75% to 100%).

My question: How can I solve this, has this to do with low linux kernel
on client-machine? Or has this to do with the fact that the client
ethernet-card is 10 MBits (and server 100 MBits)?

5) ls -l, sometimes works, sometimes not

NFS server 192.168.x.x OK.

Can anybody help me out?
Thanks. Edward

(b). If you can't set them both to auto, then set them first both
to 10 mbps half, then 10 mbps full, then 100 mbps half, etc.
Where it breaks up, back up one.

I'm sorry I can't give you a reference; I picked it up in one of the
posts I read while scanning the newsgroup(s). :-)

Good Luck!

Why so old? Just because you have an old machine doesn't mean you have to
install old Slack. I've got 9.1, kernel 2.4.22, running on a Cyrix 6X86 P150;
and I can't think of any reason it wouldn't work just fine on any old 486.

I thought I had already answered this - if they don't both have an "auto"
option, then set them both to 10MBPS half-duplex, and make it go. If it
won't go, then something's busted. If it does, then up it to 10 MBps
full-duplex, and so on. When it breaks, back up one.

Good Luck!

I'd be more inclined to think there's either a bad nic card or cable in
the mix. I've mixed 10 and 100 without trouble for years.

Thanks for the reply Rich,

How can I set them to 10 MBits half-duplex. Is this a setting for the
router? I couldn't find this in the manual. I do know that a LED
indicates that the connection is 10 MBPS or 100 MBPS. So the router must
'know' that the old computer is 10 MBits and the new computer 100 MBits.
But maybe the new computer doesn't know this abou the old one, or am I
not making sense now !

By the way. I tried an old Slackware version because I could not get a
newer version booted. I ran into trouble when I got the bootdisk or the
root-disk in (the computer just hang). Vs. 3.6 of slackware seemed to
work for mcd.i + color.gz but for NFS I need the net.i boot and when I
used this the root-disk color.gz hang on me.

I have an old CD-player that is not capable of reading CD-R's so that's
why the choice for NFS setup.

greetings

Did some research on the internet and discovered the mii-tool. I think
you meant this tool when you advised to alter the connection.

My new computer had 100baseTx-FD flow-control (link ok) and I forced it
to 10baseT-HD.
Pinging and NFS connection still the same result, bad connection.

Strange thing is that pinging from my router (192.168.0.1) to the old
computer (.3) with packages of 32 bytes is okay and from the new
computer (.2) is bad.

Can anybody give me some new insights about this. I am running out of
options (good pinging from .1 to .3 excludes bad cable I think!).
