I have discovered access delays every time I want to login to another remote machine through ssh.
It took few seconds delay before it prompts me for password. It is so irritating! And very funny, it doesn’t happens on other windows ssh client. It must be ssh config that causes the ‘delays’. I remember last time ( during the time my box installed with Ubuntu Dapper ), I didn’t face such problems.
I modified this two lines in /etc/ssh/ssh_config
GSSAPIAuthentication no GSSAPIDelegateCredentials no
By default it is set to ‘yes’, to make ssh client GSI-enabled (Grid Security Infrastructure), which used to performs the X.509 certificate handling and SSL protocol. Emm.. I do not need that.
I used to access remote machines within internal networks through ssh, therefore security is not my concern, with GSI-disable, it removes few seconds delays from ssh login. I consider that solved my problem.
