One of them might be reverse DNS lookups timing out. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/84899 Title: SSH with GSSAPIAuthentication option on SSH servers are very slow To manage notifications about this bug go to: https://bugs.launchpad.net/openssh/+bug/84899/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
