Have you done any diagnostic testing at all? I know you didn't
do any searching, as this is discussed on this list alone about
every two weeks and you would have found it if you'd searched
My first guess would be that your reverse DNS broke at some point.
Generally what happens, is that the FTP daemon is waiting for an
RDNS request to return so it has a hostname to put in the logs. If
the RDNS is broken, it waits until timeout (30 sec is the norm I
believe) before logging you in.
Easy way to find out if this is the problem is the host command.
(substitute your IP address for 126.96.36.199)
If you don't get a hostname, this is likely to be the problem.
