Re: [SLE] hmm... security mayhem...
The messages you were referring to, were in your syslog (SYStem LOG). This is a textfile that gets all logging your system does, from connects to status- and errormessages. It also logs if someone tries to get in to your system. Ususally, this file resides in the /var/log directory and is called 'messages'. You can watch your syslog on-the-fly with the command: tail -25f /var/log/messages This command (tail) shows the last 25 lines (-25f) in your syslog-file (the 'f' in -25f). You can configure how and what should show up in your syslog by changing /etc/syslog.conf If you would like to protect your system from unathorized connects, you should start to play with ipchains. Please read some docs on ipchains. Let me warn you: it's not simple! Good luck! Rogier root wrote:
Which is the syslog? are are you just telling me to infer the obvious- that connect from means conect from? or what?
None of this is simple to me. I need to be told straight up.
Thanks.

what about messages like: linux in.telnetd[4813] connect from 12.77.192.88 followed by peer died, invalid character or in.ftpd[8915] connect from 209.173.192.62 are these people connecting to my box?

But nor does it have to be insanely painful. If you have a javascript-enabled browser (crashscape works just fine), go to http://linux-firewall-tools.com/linux/firewall/index.html This will lead you through a number of steps to configure your firewall, and give you a script and instructions on how to implement it. Tweak it a little bit to suit you optimally, and away you go.
