Red Hat 6.2 - Cable Connection Wrecked eth0, lo and eth1

Hi,

My (recently installed) Red Had 6.2 system will not boot up lo, eth0, and
eth1 reliably. eth0 is set to dhcp to see my cable modem connection. eth1 is
set 192.168.1.x. ipchains is used to MASQ. It was working but now it is not.
When the system boot lo takes forever to come up, eth0 sometimes comes up on
dhcp, but eth1 just hangs and the system will not finsish the boot process.

I used my rescue disk and disabled eth0, and eth1, I can get the system to
init 5, but lots of processes seem to fail. I have noticed a few error
messages:

At the terminal level I get the message "host name look up failure"

When I start Gnome I get the message "Could not look up internet address for
myhost.mydomain.com. This will prevent Gnome from operating correctly. It
may be possible to correct the problem by adding myhost.mydomain.com to the
file /etc/hosts." I don't understand what has happened as everything was
working ok earlier this week.

Thanks,

Alan

What about using an even older distro, I have SuSE 4.2 flying
around somewhere.

Seriously, disconnect the system from the internet. It's likely
that you get cracked in a few minutes, with such an old and
full of bugs/security exploits distro.

Please, use a recent distro and apply all available patches.

Do your system or boot logs give any clue what the problems is
(/var/log/messages)?

While it could be some sort of hardware failure, if you had unpatched
telnet, ftp, ssh or sendmail daemons exposed to the internet, you may have
been subject to one of the exploits that have since been patched.

It is also possible that something in your /etc/hosts file is broken.
Did you alter the 127.0.0.1 line (which should always be localhost, but RH
also typically includes localhost.localdomain).

X may not work properly without networking, so you might change to console
login (runlevel 3) until you get this sorted out, but changing the line in
inittab something like:

# The default runlevel is defined here
id:3:initdefault:

Or runlevel 2 would boot without networking.
