Try ftp://sunsite.unc.edu or one of their mirrors.
I have a cliant with a 5 PC network using a dx2/66 8M ram 420M disk as a
mail / route / print server. Seems to work fine, but it's not doing file
serving.

Sehe ich eigentlich nicht so - im Gegenteil: das erste Paket, was
an den falschen Gateway geschickt wird, generiert ein (1) zusaetzliches
Paket, und alle weiteren Pakete muessen dann nur noch einmal uebers
LAN. Das ist gar nicht so bloed.
Eine "Verdreifachung" der Pakete kann ich beim besten Willen nicht
nachrechnen - ausser fuer das allererste Paket zu einem bestimmten
Ziel.

Subject: 2 3C509B BUT ONLY 1 can be probed
Date: Thu, 27 May 1999 18:08:52 +0800
Hi,
I try to use 2 3C509B LAN cards in IBM P100/HP Vectra running
Redhat 5.2( Linux 3.0.36). After installation, the kernel can probe
the second card( both cards PNP disabled ).
But after rebuilding the kernel and even I pass parms while
booting or add a append a line such as:
append="ether=10,0x300,eth1 ether=11,0x320,eth0"
in /etc/lilo.conf and run lilo
and add
"alias eth1 3c509
options 3c509 io=0x300,0x320"
to /etc/conf.modules
The system issue a messages:
"Delaying eth1 initialization"
during bootup process
and the eth1 is not working.
Even I issue ifconfig line manually, the system issue error:
SIOSIFADDR: Operation not supported by device
eht1: unknown interface
SIOSIFNETMASK: Operation not supported by device
eht1: unknown interface
It seems the kernel cannot probe the card!
Can anybody help me?

Subject: CONFIG_NET_ALIAS
Date: Thu, 27 May 1999 12:12:08 +0200
Hi all,
I wish to upgrade my 2.0.36 kernel to the 2.2.9 kernel.
The problem is that my machine got an IP alias (it have ifcfg-eth0
and ifcfg-eth0:0) and the 2.2.9 kernel doesn't have the
CONFIG_NET_ALIAS option in the kernel configuration. It only
have CONFIG_IP_ALIAS but it doesn't seem to be enougth.
Can someone tell me how to keep my alias even with this kernel ?
I tried to launch ifup-aliases eth0:0 but it didn't work.
Maybe a script need to be modified but wich one and how ?
Thanks

Thanks, but I've tried rinetd as per another poster (Tobias) suggested.
It does exactly what I want, easily and reliably. Thanks Tobias.
I looked at the squid and Apache doco out of interest, but couldn't find
any indications of what I wanted to do. Should I look at any keywords
in particular ?

I have no idea, but the only [1] way to be certain is to re-compile the
kernel yourself.
[1] There's probably another way to check if ICMP masq is enabled,
probably by looking at /proc or something.

No problem. In fact, don�t do anything to Linux at all. Just configure netscape
to use the Win95 box as proxy.

Try the pump update for redhat 6.0. I tried it and it still didn't fix my
cable modem problem, but you might have better luck. At least you get an
IP. My ifconfig doesn't even show eth0.

When you login over a LAN you don�t need getty at all. getty is only used for
serial logins, e.g. your virtual consoles and anything coming over a serial port.
telnetd is the program you are using to login to your system over a LAN

telnetd does a reverse DNS lookup when someone tries to connect. If reverse DNS is
not configured, it waits for a timeout, which is sometimes several minutes. Try the
command host <ip address of win box> to verify it. It should return the fully
qualified domain name of the win95 box within a couple of seconds. Else, RTMF
DNS-HOWTO and set it up correctly.

Looks like mountd is not running. Check out rpcinfo -p and see whether
mountd is actually registered at your portmapper.

Ssh1 had a feature "Allowgroups" that I used as an extra restriction

so what i would like is that for exemple every 2 hours it checks the
mail on my provider's mail server and download them. For sending mail
too, store the pending mail into my mail server and when it is online,
sent it to my provider's mail server.
There's no problem to set the connection up every 2hours (diald) but I
