Error log in /var/log/messages
 

Hi all. Need your help .. thx.

I am using Redhat 9 2.4.26

I found the following logs in /var/log/messages these days... (occurs 3~4 times this week.. no other log is found in the same time as these log:

kernel: NET: 1 messages suppressed.
kernel: NET: 2 messages suppressed.
kernel: NET: 1 messages suppressed.
kernel: NET: 6 messages suppressed.
kernel: NET: 1 messages suppressed.
kernel: NET: 2 messages suppressed.


Anyone knows what are they ?
Any bad impact to my linux box?
what should I do ??

Thanks !!

Can you launch ethereal or tcpdump.
you can match the timestamps and see what's going on..

thx...

but... how to post it out ???

Installing iptables and log all packets is also an option...
Then you'll have to see where they come from..

success

sorry , I am new to Linux..

any command / any specific files I can try to see ?



Thx for your kind help !

Hello,

I got an other problem in the log file /var/log/message which I don't understand what it is.
------------------------------
Jan 19 09:32:15 myhost userhelper: pam_timestamp: `/' permissions are lax
------------------------------

I tried: #ls -ld /

It returned: drwxrwx--x 20 root root 4096 Jan 12 12:51

What's happend? And How do I do now?

Thank you,

Hey Raymond,

Hey vhh

your root dir seems to be group writable.

success

Thanks wimdh! I've done it already.

Why did it show me the notice under username "userhelper"? Did someone hack at me?

Anyway, thank you.

Hi vhh

userhelper is a part of PAM
try man userhelper.
PAM reported the error when someone autenticated I think...
