Delays like this are typically related to DNS. I'm guessing that your
FreeBSD/Linux system doesn't have valid reverse DNS set up. You can
either set up correct reverse dns, or just twiddle UseDNS in your
/etc/ssh/sshd_config file. From `man sshd_config`:
UseDNS Specifies whether sshd should lookup the remote host name and
check that the resolved host name for the remote IP address maps
back to the very same IP address. The default is ``yes''.
Also you can try using ssh -v to see where the holdup is.
HTH,
