I'm not sure about ftp, but most telnet servers will do reverse lookups
on the incoming address. I know in the VMS product I maintain there are
ways to disable the lookups, but I'm not sure with a product like debian
(all though you could of course go into the code and change it :)
Anyway... check your resolving on the reverse addresses for your source
address. Are you running a name server for the PTR zone [e.g.
1.168.192.in-addr.arpa]? Is anyone? Can your resolver resolve to the
root servers? Try:
nslookup -type=ptr -d 1.1.168.192.in-addr.arpa
(Or whatever the reverse of the source address is)
nslookup -d 192.168.1.1 (or whatever the source address is)
I'm pretty sure with BIND resolver implementations, the /etc/hosts file
is checked _after_ remote lookups are attempted. If you have a
misconfiguration that causes the reverse lookup to have to timeout
before getting to look locally.
