Answering some sugestions made for some in the list:
1) I am not running multi-threaded process (process threads).
--
2) While I was running chkrootkit-0.39a:
Checking `ps'... not infected
...
Checking `lkm'... You have 54 process hidden for ps command
Warning: Possible LKM Trojan installed
--
3) Seeing process:
[root@localhost chkrootkit-0.39a]# ps ax
PID TTY STAT TIME COMMAND
1 ? S 0:04 init [3]
2 ? SW 0:00 [keventd]
...
4881 pts/0 S 0:00 bash
4917 pts/0 S 0:00 vim rootkit
4918 pts/1 R 0:00 ps ax
Total: 52
At /proc : 52 process, too
--
4) There are no new open ports listening.
--
5) And, is this *normal* ?
[root@localhost /]# lsattr -d /proc/
lsattr: Inappropriate ioctl for device While reading flags on /proc/
--
6) Modules are being loaded are usual, nothing that I don't want.
--
7) Unfortunately, I don't have access, yet, to a CD like Knoppix. :(
--
8) I probably gonna try the way: boot up the system with a 'clear'
kernel (no modules).
Thanks in advance, again...
Rivanor.
