Hi All, All of my systems are running 5.4 x64. The are all AMD x64 processors with at least 2gb of RAM in each. I am running SSH on a non standard port. When I SSH into ANY of my systems, I get prompted for my password right away, but after entering, it takes 30+ seconds to get logged in and get a prompt so I can work. I dont quite know what to look for here Does anyone have thoughts? -Jason

Brett, Les, Thanks for the pointer, this worked. I knew it had to be DNS or maybe my system was really busy, but it is a very small web-server. -Jason On Jan 18, 2010, at 3:12 PM, Brett Serkez wrote:> In /etc/ssh/sshd_config change: > > UseDNS yes > > to > > UseDNS no > > Brett > > On Mon, Jan 18, 2010 at 6:08 PM, ML <mailinglists at mailnewsrss.com> wrote: > Hi All, > > All of my systems are running 5.4 x64.
