this shows your box has some other problems too, paste this code in your box then wait for any errors
Code:
mv /var/log/messages /var/log/messages-bk
touch /var/log/messages
chmod 600 /var/log/messages
tail -f /var/log/messages

it's done tail -f messages has not reported any output

thanks a lot

I was reading this for a similar problem is spanish but it says about a rootkit

Warning: cannot create backup file `/etc/passwd.old': Operación no permitida - ForoSUSE

I run rkhunter 1.3.8 since chkrootkit 0.47-1.71 was not able to run for this error

Code:
chkrootkit: can't find `netstat'

I am adding the rkhunter log

I found 2 more system with the same issue for passwd and useradd
so seeing the rkhunter log I have basically 3 questions

Does it look like a rootkit thing?
Second
Do you think someone might be able to not install those binaries?
Third
is there a way to find which other binaries-commands are these system missing? and if it a good idea to copy passwd - useradd from another system?

thanks a lot guys

Which version of SLED, SLES or OpenSUSE are you talking about?

you need to have another box with clean install your current OS on it , then list all /bin /usr/sbin /sbin /usr/local/bin /usr/local/sbin paths , and check and verify the existence of the binaries on your main box.

my linux us Suse 11 SP1 x64

I meant since I've found 3 servers with the same issue if maybe someone did not install these passwd-useradd binaries....

---------- Post updated at 11:02 AM ---------- Previous update was at 10:27 AM ----------

what about my last question....

In order to fix this can I copy these binaries from another running system?

thanks a lot
