I had this problem in the past, and it was due to DNS problems where my IP from the client machine was unable to be resolved... but I think it took longer than 40 seconds. I mentioned this in this list before, a search of the list may help. rjv -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of Phusion Sent: Sunday, June 05, 2005 6:11 PM To: Robert Marella Cc: freebsd-questions@freebsd.org Subject: Re: ssh delays 40 seconds I've noticed this same thing on one of the machines I've built in the last week. The machine is running FreeBSD 5.4-STABLE with OpenSSH 4.0p1. The delay is probably about 30 seconds. Also, the machine isn't being used by anyone at the time. This happens when connecting from one local machine to another local machine on the same LAN. On 6/5/05, Robert Marella <rmarella@gmail.com> wrote: > A little nudge is needed.
