Cannot login anymore all of a sudden...

Hello all,

I have a pretty good working Slackware-current system.. well HAD a good working system. Right now I cannot figure out what is wrong. Yesterday all of my system was still working fine. Today it isn't... I cannot login as root (not at console, the 60s timeout thingy, nor in ssh). Normal users are 'picky': my own account took me like 5 tries before I got through the barriers of console and ssh. Root is 100% blocked tho

I already checked all the things I could think of but I ran out of ideas. As a last resort, I rebooted but it gave me no login chances still .

Things I did in the last few weeks (I don't turn it off, linux is made to stay up ) since it might be many of these... latest first:

- Forgot to write away router logs before, enabled it in syslogd. Changed the switch to -r in one of the bootup files, changed the syslogd.conf and everything worked fine.
--> Just checked if /var partition was full... none of the partitions are. All have atleast 100M free.
- Changed root password. I do this once in a while, only difference with normally is that I read that longer passwords are better. So I changed a 6 letter one to a 13 letters one.
--> Tried logging in with caps lock on (well... might have changed it with capslock on.. ), various typo's I know that I make occasionally.. but no luck. Even worse, ssh locked my ip/mac or whatever it is, out right now :|
- About a week ago, I carefully replaced all current rc.* files so that they are up to date. I ofcourse have backups. Never rebooted then, since there was no need and chance at the time.
--> They were not used before the reboot I think, so I don't believe they are the problem. Bootmessages seemed fine today...

ps | aux before the reboot showed many smbd and sshd processes, the last were Z zombified... Hence I rebooted, only way I could solve that problem without root...

I hope anyone can help me, even though my system can still do what I expect of it without my seat , I would like the driverseat back so I can drive with raw penguinpower

Thanks for reading everyone

you may have changed the permissions of some/all of the "rc" files and the
system may not be able to read from them to start system services........

just a thought.......

<edit/> some of those "rc" files are $SHELL SCRIPTS and need to be
executable for some of the system services to start up.........

For as far I can see all the rc.* files I need are marked with a * (executable).
Here is the ls output: (once again, am using Slackware, so unused scripts are usually marked by not-executable)

Maybe you've been entering your password wrong. Did you check to see if you could log back in after you had changed it?

Yes I checked at the time and it worked. Just seeing that it has been changed succesfully isn't enough... I prefer to be sure..

Well I guess I am going to see if the night brings any suggestions... Thanks all
