I’ve seen some blog posts on the planet lately about groups getting their Lucid discs. Ours (KY) haven’t arrived yet. Last time somehow my email request got lost in the shuffle. Hope that wasn’t the case this time.

As many have seen, Fedora 13 has a slogan now. That would be “Rock it”. I think this is a great slogan. The other nominations can be found here. The release name for Fedora 13 will be “Goddard” named after Robert H. Goddard a real life rocket scientist. Maybe it is because I have kids but whenever I here Goddard I don’t think of rockets. I think of Jimmy Neutron’s robot dog that shares the name. That is probably caused by the numerous hours that the 3 of us spent watching the show.

I mentioned a post or so ago about a new application that I have started to run called logwatch. One of the things that I noticed in the output that I was getting from log watch was a fair number of failed ssh log in attempts. I looked like most of the attempts were automated hits using root/password to get in. This got me looking into a way to stop these types of attempts from happening. A quick google search lead me to denyhosts. It is a really simple but effective app that watches for failed attempts and will put the offending IP address in your
The only issue that I had once installing it was that my own IP was being blocked from my laptop while on my wireless connection (weird). To fix this I edited
/var/lib/denyhosts/allowed-hosts to add my IP info to keep me from being blocked.
grep sshd: /etc/hosts.deny | wc -l I can see that my hosts.deny file has gone from having no entries to having 100. And that is just in the timespan of a month or so.

This is just a test post. If all goes well then this should show up on the Fedora Planet.
Looking at this site today I noticed that I had not posted anything at all since April. I knew it had been a while but I didn’t realize it had been that long. One of my many goals for this year is to try to post at least one time per week to this site. I plan to try to post about new applications that I have found. Many of these applications will be old hat to quite a few people but they are new and exciting to me.
The first application that I will talk a little about is logwatch. It is kind of funny how I came to learn about this one. I had been watching some RedHat SysAdmin class material during some of the boring days at work during the holidays. I kind of glazed over the section on logwatch but then it came back to me when I saw a post by Juanjo Martínez on the Fedora planet. I installed and configured it on a Fedora 12 machine that I use at work and was really impressed with the amount of information that I got from it. What really sold me on it though was when I installed it on my Ubuntu server at home and I was able to see how many times people were trying hit it over ssh. Finding this out led to the next tool that I recently found which I will discuss next time.
Reviewing logs is a very important part of a sysadmin’s job in my opinion and I feel bad for not know about this tool for so long. If you are not running logwatch now and want / need something that will help you get more information about your system then I highly recommend it.
On May 9th from 4 – 7 PM (EST) the Ubuntu Kentucky LoCo along with the Blue Grass Linux User Group will be hosting a release party for Jaunty Jackalope. The event will be held at Tates Creek Christian Church in Lexington Ky and is open to the public. There is a facebook event for the party to help us know a rough number of how many to expect. With any luck I will have received the CDs that we ordered and will be able to pass them all out to those that come.
