Help with pam_unix error message?!?


Hi there,

I'm kinda getting frustrated with the error messages i'm getting currently.

I'm pretty new to linux, and specially to fedora.
Currently I'm running Fedora Core 4.
I also updated all packages from Fedora through webmin (as this is a dedicated server I'm renting at a co-location) because I don't have access to a GUI.

To make something clear.
When I got the server (which is like 5 weeks ago) there where NO error messages like this!!!! (just in case people wonder if it came with these errors or not)

Now before I started updating I noticed the following messages in the log file:

crond(pam_unix)[5635]: session opened for user root by (uid=0)
crond(pam_unix)[5635]: session closed for user root
crond(pam_unix)[5717]: session opened for user root by (uid=0)
crond(pam_unix)[5717]: session closed for user root
crond(pam_unix)[5795]: session opened for user root by (uid=0)
crond(pam_unix)[5795]: session closed for user root

That was the main reason for me to start updating..
Thinking it would be solved updating all server packages.

Not happened of course.

I'm still getting the same error messages as above.

Is there anyone that could help me out on this issue, as i'm starting to get pretty annoyed because of them.

And it also concerns me. Is this a security breach? If so, what can i do about it?

I really hope someone can give me some information regarding this.

Thank you for reading and kind regards,

Jorge Valencia

As you can see this message apears every minute.

Nov 23 19:40:01 crond(pam_unix)[5635]: session opened for user root by (uid=0)
Nov 23 19:40:01 crond(pam_unix)[5635]: session closed for user root
Nov 23 19:41:01 crond(pam_unix)[5717]: session opened for user root by (uid=0)
Nov 23 19:41:02 crond(pam_unix)[5717]: session closed for user root
Nov 23 19:42:01 crond(pam_unix)[5795]: session opened for user root by (uid=0)
Nov 23 19:42:01 crond(pam_unix)[5795]: session closed for user root

Anyway, thanks for your help.

This is nothing really special. Someone (or some automated service) does su, which means he becomes root.

You could look at what cron is doing (cron is a daemon which starts programs at special times, every minute or just like you set it).
