Learning Linux Ssh Login Brute Force Web Server

Oh my goodness... I thought I was a patient person.

Today I noticed that my server was getting hit on by people trying to do Brute force SSH logins, on my web server. Otherwise , the server was running just fine.

I posted this message a little earlier, and then I got some replies.
I also checked out google groups for answers to my problem and the web in general. Being a novice to linux my head was completely spinning. People were saying try this and try that.

While I very much appreciate the help, I spent the whole day learning some fundamentals of linux so that I could barely understand what they were saying.

This exact same thing happened last week. My linux mail server running qmail was getting hit on from people spamming me. Otherwise it was working just fine. Being a complete novice to qmail, I tried to fix the problem and had it fixed for 10 minutes before I buggered it up again.

This time the problem was worse because not only did I not know about linux, I didn't know about the qmail email program.

The alternative is to bring in a technician who charges $100 per hour and I would be out the money and not understand the problem anyway.

THE GOOD NEWS:
Despite the blistering headache and numbness in the eyes, I started to get a better feel for how linux works and how to move around, unzip (untar) files , use wget, yum etc.

I wish there were more enjoyable things to spend a saturday on , however this is it for the moment.

I've learned the hard way , that the best way to learn about something is slow and steady, little by little.

Linux is a good operating system, but I can see why the majority of people would gladly stick with microsoft's products!!

Newbie question cd var/qmail/bin/ linux

Hello,

I noticed that my /var/log/secure linux file was getting to be 57MB's and hadn't been cleared since we installed the machine a few years ago.

I copied the secure file to secure.old and then made a new secure file. I chmod'd the file to 600.

I also did cp /dev/null /var/log/secure .. which i read about on
google.groups.com

I'm not sure if there is anything else to do... or how I would know that
everything is ok with this file.

I tried logging back on /ftp'ing on to this service and I'm not getting any log records in the secure file.

Any ideas?
