Thanks Olivier, that solution fixed my Samba problem as well.
What's really annoying for me is that "Win 95 bug fixes" is set "on"
for the standard RH6.0 system that I'm using and the RPM upgrade
kernels. So, when I was recompiling the kernel for something else,
I set the W95 bug fixes flag to off and promptly forgot about it.
Why? Well, I changed it to "off" on the recommendation of a post
from one of the Samba team in the RH mailing list. Supposedly, with
my Win98 system, using the kernel Win95 bug fixes setting would
cause bad time stamps.
While getting the other hardware device working, Samba wasn't
getting used much of the time, but a few weeks later I was pulling
my hair out wondering what happened to the "Network Neighborhood."
The morale of the story is that when you start goofing with the
kernel, do one thing at a time. :)
Now, time for a little email, it looks like the Win98 users needs
the bug fixes too.

Subject: Cable Modems
Date: Mon, 16 Aug 1999 20:49:34 -0500
Hi, I am looking into getting a cable modem. Before I call my cable
provider, I'd like to be sure I can use this in Linux. (And I'm guessing the
provider will be of no help if I don't know what to ask them).
Does anyone have this set up? Should I get a certain type of modem? What
questions should I ask the provider to be sure it will work under Linux and
Win98? How can I figure out if my existing network card works under Linux.
(I've never used it in anything under linux).
I'm running Caldera OpenLinux 2.2 on a Compaq Presario (PIII)
Thanks in advance!

Hmm, that's what you pay 70 bucks for? That sucks. have you tried putting
the IP of the machine your telnetting in from in /etc/hosts, combined with
a hostname? This sounds like telnetd is trying to reverse resolve the
ip of the connecting client, and can't.

This might work for Linux 2.0 if you care about the routes too by adding
the same routes as are existing for eth0 to eth0:1 too and delete the
old ones after. But for Linux 2.2 shuting down the original interface
with ifconfig does catch the alias device too. I'd recommend using the
iproute2 utitlity (namely the program "ip") to add an alias address
(this is possible now without creating an alias device), create the new
telnet session as above and delete the old address later on.
To move from 192.168.2.1 to 192.168.2.6 following should work:
ip addr add 192.168.2.6/24 broadcast 192.168.2.255 scope global dev eth0
# create new telnet session to 192.168.2.6 now!
ip addr del 192.168.2.1/24 dev eth0

It's perfectly correct. How can a IP netmask consisting of 32 bits like
an IP address contain 213 bits setted to 1?

Just give it a valid netmask.

Bus errors are most often caused by mismatched libraries. Run ldd on
your netscape binary and make sure your libraries are up-to-date. And
just b/c it's a web browser doesn't make it a networking

The card looks OK. Run the 'route' command (or netstat -r) and see if you have a
route pointing to eth0. You should see something like:
Destination Gateway Genmask Flags MSS Window Use Iface
130.60.93.0 * 255.255.255.0 U 1436 0 4189 eth0
You might have to add one:
route add -net 130.60.93.0 dev eth0
This tell the kernel that anything for the 130.60.93.0 network needs to go out
through eth0.

All of my NT servers and NT workstations can see my Linux/Samba in the

load printers = yes
guest account = nobody

encrypt password = yes
smb passwd file = /etc/smbpasswd
unix password sync = yes
passwd program = /usr/bin/passwd %u
sockect options = TCP_NODELAY
interface = I'm not sure exactly the way this option works. using
______"192.145.10.63/24"
remote browse sync = 192.145.10.5
remote announce = 192.145.10.
domain controller = main
with wins I've tried having the samba server be both the wins server
syncing browse list with 192.145.10.5 and just a wins client and I have
changed the win9x box to use it as a wins server/ and tried all 3 browse
master options. also have tried using Samba as a wins proxy.
DNS - working fine
and then my shares
I've been looking through newgroup after newgroup and tried everything and
it is still not working. Any suggestions will be welcome.

Your isp is most probably running a firewall. One that blocks incoming
icmp packets ( eg ping ). It can be a blessing ( no ping floods from out
side the network ) or it can suck ( no replys to icmp packets you send ) .
Judge according when choosing whether you want to stay with your isp or
change to new one.
