You could also crank up the logging for the server side in [probably] /etc/ssh/sshd_config to see what it thinks is happening. You did check the logs, right? And, yes, it could be the server trying to do a DNS lookup. Does DNS resolution work on the jail? If it is broken and you don't want to fix it, start fiddling server side settings such as UseDNS. --=20 --Jon Radel jon@radel.com --------------ms070308090108020006010409 Content-Type:
