[Bug 84899] Re: SSH with GSSAPIAuthentication option on SSH servers are very slow

[Robie Basak]

I use plenty of servers without Kerberos and I never see this. I don't
think it's clear that having GSSAPIAuthentication on by default is the
problem. I think it's more likely that there is some other cause, and
turning GSSAPIAuthentication off is merely a workaround.

I also suspect that reporters have a number of different underlying
problems. One of them might be reverse DNS lookups timing out.

Title:
  SSH with GSSAPIAuthentication option on SSH servers are very slow

Status in Portable OpenSSH:
  New
Status in “openssh” package in Ubuntu:
  Confirmed
Status in “openssh” package in Debian:
  New

Bug description:
  Binary package hint: openssh-client

  In Feisty Fawn I noticed a very slow ssh connection to some local servers, the prompt login takes 5/6 seconds to appear.
  I solved this problem putting the option "GSSAPIAuthentication no" instead "yes" in the /etc/ssh/ssh_config file.

  SSH Version is 4.3p2-7ubuntu1
