urgent problem (server hacked), result: "segmentation fault"
I've had a server hacked on my network running on CentOS (trixbox).
the root password was changed by intruder. so I tried to reboot using single mode on grub, however the disk was on READONLY and couldn't write passwd file.
So I reboot using trixbox CD and linux rescue option, and I managed to restore the password. but when I do mount -o remount,rw / it gives "SEGMENTATION FAULT"
when I do ifconfig i get the same thing and the eth0 comes up with "promiscuous mode" error which is another odd thing.
I tried to scan the kernel with chkrootkit and it was suspected on some of the things but did not give any information how to fix it.
I'm sorry to say this but I'm not a linux guru since I've been on Microsoft platform for a decade and now migrating to linux.
so if you know the solution to this please explain in basic steps that I can run.
Thanks a lot
