Comment 4 for bug 77943

I am running Ubuntu server edition and was surprised to see so many attacks on my /var/log/auth.log*

# zcat /var/log/auth.log.* | grep Failed | less

I think if Ubuntu wants to push the server to the next level it must ensure security, reliability and speed. Is there a reason why and IP blocker tool is not integrated with the sshd daemon?

Should I open a feature request and propose this on Feisty+1 or do you think that this is something that the sysadmin should configure him/herself if needed?

We could use the fail2ban tool suggested above but these are other tools that seem to do a similar job. Unfortunately we do not have packages for any of them:
