I've been using denyhosts for a while and I noticed my /etc/hosts.deny
is getting rather large. Denyhosts adds IPs to /etc/hosts.deny
, and my denyhosts is configured to never purge IPs.
$ wc -l /etc/hosts.deny
22149 /etc/hosts.deny
Might this become a problem? I don't really understand how libwrap works. Hopefully it is hashing these entries or something for quick access, but I haven't looked at that code.
I am having some strange networking issues where my SSH connections to a gitosis server are hanging (actually, updates of Symfony2 bundles using bin/vendors install
). I'm not really sure how to debug it, so I'm looking for things that might be going wrong with the box, such as resource shortages.
This is on an Ubuntu 10.04.4 LTS server.
