Configure the SecureCRT ssh key to log on to the remote host.

[Ggp @ test182 ~] $ Ll. sshtotal 8-rw-r -- r -- 1 ggp 588 Sep 25 authorized_keys [ggp @ test182 ~] $ Ll. ssh/authorized_keys-rw-r -- r -- 1 ggp 588 Sep 25. ssh/authorized_keys [ggp @ test182 ~] $

Remember to change the. ssh permission to 700, and change the authorized_keys permission to 644. The above two permissions seem to be appropriate.

The user and group of. ssh and authorized_keys are ggp. ggp instead of root. root.

Otherwise, you may not be able to log on normally.
