Miscellaneous Options
This page contains options that don't fit into any of the other categories. Some of the less obvious options but useful are :
Allow X11 connection forwarding?
If set to Yes, users that make an SSH login from a Unix machine will be able to run X applications on the server and have the X connection tunnelled back through the SSH connection to their local display.

System log facility
The syslog facility that is used to log error and information messages from the SSH server. This can be used in conjunction with the System Logs module to control which file SSH messages get written to.

Server key regeneration interval
How often the SSH server re-generated the key used for encrypting connections. If you are paranoid about security, set this to a lower number.
