Hi i'm new here and i'm a linux newbie as well, so forgive me for my stupid questions.
My Mail Server running SuSe Linux 8.1 broke down today. I had to move it. After restart it came over with segmentation fault. I checked the hardware by swapping with other parts but the error presists. If I boot by CD everything runs fine.
Is it possible that it s no hardware problem and how can I get this problem solved without reinstalling the server?
It may be a faulty segment on the HDD that a boot
of CD wouldn't unveil .... which process in the boot
segfaults? Once you know that you can ask for a
ldd <process> and check the HDD for readability
of the executable and the libs it needs ...
I ran an install over the server again. Now it works fine again. All Services still running fine. But I can't login as root anymore. It doesn't accept the PW. What can I do? I think that one of the users tried to login as root several times without the knowledge of the pw. How can I check that?
If you have permissions to read /var/log
and the files therein you should be able
to read /var/log/secure
But I haven't heard of any Linux distro that
would disable the root account because of
failed login-attempts ... that would be the
easiest DoS attack ;)
Thx, anyway. I'll check /var/log/secure. Hope ihave the rights to do that.
And for that PW? Does that mean I have to build the server from the scratch?
The easiest thing would be to boot into single
mode and change root's password. Have a search
here, I've just pointed someone to a way of doing
this a day or two ago.
