server-side ftp autorization delays

Hello,

I experience several-second delays when solaris 8 ftp server
accepts login/autorization. Delays appear not for all clients.
Clients are on LAN so it's not network speed issue.

Delays seem to appear only for clients which are not in DNS.
When I remove dns from /etc/nsswitch.conf , delays go away;
ftp login becomes immediate. The "hosts" line in nsswitch.conf is

      hosts: files dns wins

How can I remove those delays ? Putting the client into /etc/hosts
doesn't help. Strange. Does server try reverse-dns or something ?

But I cannot permanently remove dns from /etc/nsswitch.conf, and
I cannot add unix clients to DNS ... dns server is windows machine
... managed separately.

Is there ftpd option to remove those delays ?

Thanks
Yakov Lerner
