Subject RE: [users@httpd] Apache cannot start anymore
Date Tue, 08 Apr 2003 12:52:41 GMT
It would really help a lot if you could post in plain text (can't inline
quote you otherwise)..

Apache is hitting a segmentation violation while reading /etc/protocols.
I've no idea why this would happen.

You mentioned in your very first mail that you'd "reinstalled apache".
How did you do this?

Also, all this trouble started after you'd been "attacked" - did, or do
you even suspect that, a hacker gained access to your machine? If so,
never mind re-installing apache, you'd better re-install the OS! You
might also need to re-install the user data from back-up (you do keep a
backup, don't you?) If your system is corrupted many more things besides
apache may be broken and you may have logic bombs or trojan horses or
back doors lurking on your system.

Generally, the procedure for recovering a hacked machine is:

- unplug every wire except the ones connected to the keyboard and mouse
- format the disks 
- re-install the OS from CD
- re-install user data from backup tapes recorded BEFORE the attack
- put all the wires back in

This is why most people go to a lot of effort not to get hacked...
