For example:

DenyGroups staff

DenyUsers

Use this directive to deny login for user names that match one of the specified strings. This directive

must be followed by a list of user name strings separated by spaces. You can use the star (*) and

question mark (?) characters as wildcards in the strings.

NOTE: Only user names are valid; numerical user IDs are not recognized.

If the pattern takes the form USER@HOST then USER and HOST are checked separately, restricting

logins to particular users from particular hosts.

By default, login is allowed for all users.

For example:

DenyUsers Clay@zin.org Arian

This command denies login to user Clay, connecting from zin.org. It also denies login from all

addresses to anyone logging in as Arian.

DisIStrip

Use this directive to specify whether to disable ISTRIP for tty connections. By default ssh ptys

set ISTRIP. Setting this directive to yes allow users to use multibyte chars.

The default is no.

For example:

DisIStrip yes

Use this directive to specify whether to increase the limit of X window pseudo-displays to 2000.

By default the limit is 1000.

For example:
