Hi List;This kind of delay is most often associated with failed reverse DNS
lookups (attempts to resolve an IP address to a name). Wireshark (nee
Ethereal) will show the DNS traffic if this is the case.
I looked at the archives and google's this issue with no success. I've setup
winXP with Cygwin and installed the ssh-server.
With the ssh service running I can connect from an external box via ssh but
the connection takes at least 30seconds before I get a password prompt, and
in some cases takes over a minute.
Thanks in advance for any help, thoughts, comments, etc...
Typically the client wants to display the server's name where it can,
instead of its IP address. The simplest way to address this is to put a
server entry in the client's /etc/hosts (or Windows equivalent).
More generally, perhaps something like the following might work:
# echo 'UseDNS no' >> /etc/ssh/sshd_config
# /etc/init.d/sshd restart
Hope this helps.
