I have been looking through some of the questions and I believe they would be impossible without a custom coding solution (prove me wrong, I hate duplication of work, therefore, why I am here). I am very new to this server stuff. I look at a question like this:
fail2ban custom action to permanent ban IPs from Chinafail2ban custom action to permanent ban IPs from China
and think to myself. The fail2ban code isn't that large (well in comparison with something like apache) maybe this is a something I would like to put some time towards and generally improve the open-source community.
I would assume that an answer of "see my github" would be frowned upon here. I can't take it to stack overflow since I am not asking a question nor would they support a question about how to configure fail2ban.
tl;dr; How would I submit custom coding solution to fix problems here.
Note: I am ignoring that the question would most likely be closed before I have a chance to finish.
Note 2: I have no idea how long it would take a patch to get into upstream, but I am assuming that it would be much too long for people who have immediate problems
