I found my own solution. Thanks to a number of folks who responded. I hadn't seen a console message that was popping up when logging in, and a google search of that error provided the solution. It's apparently a bug, with a workaround in how ssh handles a system with only IPv4 addresses. The console error I was getting was: "error: Failed to allocate internet-domain X11 display socket." Upon doing a little google-ing, I found a couple of sites that describe the problem and workarounds. http://groups.google.com/group/mailing.unix.openssh-dev/browse_thread/thread/8bc4833f84f05ce3 http://dbaspot.com/forums/solaris/397531-s10-sshd-x-forwarding-problem.html Basically, the workaround I selected was to bring up an IPv6 loopback interface, and all new ssh sessions create X11 sockets correctly.
