Dear all, I have written an article how to block cracker using denyhosts. This is the excerpts: Internet is a cruel world. Server owner that is always connected to the internet knows this. Crackers are always trying to hack into our server day and night, 24 hours, 365 days non-stop. How do we secure our server? There are many ways to do it, one of them is using denyhosts. With it, we can block those crackers after certain amount of failed login attempts.
The article can be found at: http://linux2.arinet.org/index.php?option=com_content&task=view&id=1...
Knowledge belongs to everyone,

You might want to add a few lines describing how to add the appropriate yum repository so the user doesn't see:
[root@somehost ]# yum install denyhosts Gathering header information file(s) from server(s) Server: CentOS-3 - Addons Server: CentOS-3 - Base Server: CentOS-3 - Extras Server: CentOS-3 - Updates Finding updated packages Downloading needed headers Cannot find a package matching denyhosts No actions to take #
8-)
Cheers,

You're right, I forget to tell about the rpmforge repo. I add it in the comment. Thanks.

---- the thread on the fedora-list has pointed out that the denyhosts rpm packaging by rpmforge is deficient when compared to the packaging done in fedora extras which correlates to all the extra steps necessary in your write up.
you might want to...
1 - provide a suggestion to rpmforge of the post-install scripts used in the spec file of the fedora-extras packaging so rpmforge does the same
2 - provide a suggestion to rpmforge that they remove the fedora-core 4 & 5 packages since fedora-extras is packaging them already and there is a conflict

I'm sure Dag is monitoring this list. By the way, is it ok to use FC package in Centos? How far is the compatibility? Or is it that we shouldn't use it at all for the sake of security and stability?

---- you got me there. I know that dag's package is a noarch package and it is AFAICT just python scripts so I don't know why the fedora package is labeled arch specific. Probably should ask Tibbits on that.
