2. and how to replace with uninfected binaries (procps, init-scripts, may i do uninstall the rpm and replace with the new ?)
3. when i do shutdown -h now or shutdown -r now i got some error afterall
/dev/null RK_Init idt=0xc036f000, sct[]=0xc030a0f0
**** : can't find kmalloc()!
is it safe to reset from reset button ?
thanks for your concerned
If your system has been rooted, get it off line NOW.
As for just reinstalling binaries, how do you know what's been replaced with what? It needs to be totally formatted and reloaded from scratch. Otherwise, you may end up being rooted again because you missed a critical file that was replaced to allow access back into the system.
SuckIT installs default built binary called "sk" as /sbin/init. SuckIT (if unmodified) will uninstall itself when you call the "sk" binary with argument "u". So "/sbin/init u" should unload SuckIT. This by no means means you're in the safe zone.
Use your rescue CD (often your installation cd) for any operations on that box. Don't boot from the kernel on your hard drive!
Basically, you have no idea what the person who has rootkitted you has done to your box, what backdoors they have opened, etc. The only way to be sure that you are safe after a rootkit infection is the three "R"s: repartition, reformat and re-install from scratch
And as an addition to the reply of Flatline: update your system frequently after reinstall.
Pardon my ignorance guys, but is SuckIT a kind of trojan that infects Linux? I've never heard of it before. Will Shorewall keep it out (I've just installed Shorewall thanks to Flatline).

Not exactly, Martin. A root kit is a set of tools used by someone to maintain control of a system after he's broken into it.Quote:
