Description

Provide Telnet connections from remote systems to the local device.

Options

authentication-order [authentication-methods

Configure the order in which the software tries different user authentication methods when attempting to authenticate a user. For each login attempt, the software tries the authentication methods in order, starting with the first one, until the password matches.

Values: Specify one or more of the following authentication methods listed in the order in which they must be tried:
- ldaps—Use LDAP authentication services.
- password—Use the password configured for the user with the authentication statement at the [edit system login user] hierarchy level.
- radius—Use RADIUS authentication services.
- tacplus—Use TACACS+ authentication services.
Default: If you do not include the authentication-order statement, users are verified based on their configured passwords.

connection-limit limit

Configure the maximum number of connections sessions for the telnet service per protocol (either IPv6 or IPv4).

Note:

The actual number of maximum connections depends on the availability of system resources, and might be fewer than the configured connection-limit value if the system resources are limited.

Range: 1 through 250 connections
Default: 75 connections

rate-limit limit

Configure the maximum number of connections attempts per minute, per protocol (either IPv6 or IPv4) on an access service. For example, a rate limit of 10 allows 10 IPv6 telnet session connection attempts per minute and 10 IPv4 telnet session connection attempts per minute.

Range: 1 through 250 connections
Default: 150 connections
