I confirm this problem in Ubuntu 10.10. I experienced the exact symptoms as described in https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/416264, but I think the bug belongs to #84899.
Ubuntu uses the Debian package, as shown at the top of the attached file (personal information removed): OpenSSH_5.5p1 Debian-4ubuntu4, OpenSSL 0.9.8o 01 Jun 2010 The remote server is running Red Hat, which has /etc/ssh/ssh_config with: GSSAPIAuthentication Yes I have no access to modify the remote server's files. So, I think the problem is bigger than just Debian. I created a user ~/.ssh/config file to contain: GSSAPIAuthentication no The work-around fixes the problem, access is very fast. ("cat /proc/version" will display the distro name, "uname -a" does not display the distro name.) ** Attachment added: "ssh -v showing authentication problem." https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/84899/+attachment/1735960/+files/ssh-with-bug.log -- SSH with GSSAPIAuthentication option on SSH servers are very slow https://bugs.launchpad.net/bugs/84899 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
