timeouts from one machine and not another

[David Bishop]

Sorry, I should have made it more clear.  I get this hang on all
connections that I make, whether it is smtp or ftp.  Interestingly
enough, I do *not* get the hang when using ssh, http, or domain.  
Could this be some sort of pam thing?  I don't know enough about 
pam to really say. The ftp daemon, exim, and sshd are all started as 
seperate services (not via inetd), so that startup isn't an issue.

I'm going to start looking at pam, see if that leads me anywhere.

*update* Doesn't happen with pop3 or imap, either.  So it's just ftp and
smtp.  

*update to my update*  Now it isn't happening with ftp either, just
smtp.  But reverse dns lookup is turned off, I swear it is...  And it
definetly was happening with ftp before.

- Very Confused
