Syntax ssh server acl acl-number undo ssh server acl Default An SSH server allows all IPv4 SSH clients to access the server. Views System view Predefined user roles network-admin Parameters acl-number: Specifies an ACL by its number in the range of 2000 to 4999. Usage guidelines You can use this command to filter the IPv4 SSH clients' request packets by referencing an ACL: • If the ACL has rules configured, only the IPv4 SSH clients whose request packets match the permit statement in this ACL can access the server. • If the ACL does not exist, or if the ACL does not have any statement, all the IPv4 SSH clients can access the server. The ACL filters only new SSH connections after the configuration. If you execute this command multiple times, the most recent configuration takes effect. Examples # Configure ACL 2001 and reference the ACL to allow only the IPv4 SSH client at 1.1.1.1 to access the server. system-view [Sysname] acl number 2001 [Sysname-acl-basic-2001] rule permit source 1.1.1.1 0 [Sysname-acl-basic-2001] quit [Sysname] ssh server acl 2001 Related commands display ssh server ssh server authentication-retries Use ssh server authentication-retries to set the maximum number of authentication attempts for SSH users. Use undo ssh server authentication-retries to restore the default. Syntax ssh server authentication-retries times undo ssh server authentication-retries Default The maximum number of authentication attempts for SSH users is 3. 164
