I hope this patch is safe. It is restricted to hostnames up to 63 bytes long. Please include it into upstream if you'll find it useful. It is possible that during some days I'll add username to make information more complete and if it will be welcomed I'll sent it too. The best way is - of course - to make this feature configurable, but I am not experienced C programmer so I cannot do it :-(

In the patch file you should have put:

--- src/main.c  Fri Nov 14 21:43:12 2003
+++ src/main.c  Fri Mar 18 15:36:41 2005

instead of:

--- main.c  Fri Nov 14 21:43:12 2003
+++ main.c  Fri Mar 18 15:36:41 2005

otherwise the patch application can not understand what file to patch.
This is a simple correction (look at the attachment)
