Optimizations for long wait times for Linux remote

Recently found that most of the production server used in the work, through the Securecrt/xshell/putty terminal software to SSH connection, waiting for the prompt to enter the password for a long time, always need more than 5 seconds, after observation found that the original is Sshd_ The cause of configuration in config;

Vim Open/etc/ssh/sshd_config

1. Find "Gssapiauthentication yes" to modify it to "Gssapiauthentication no"

2. Find "Usedns yes" to modify it to "Usedns no"

Restart SSHD Services: Service sshd Restart | | /etc/init.d/sshd restart

At this point, you can ssh to the server again to see if the speed has become faster.
