Telnet Server

Submenu level: /ip service

Description

Telnet protocol is intended to provide a fairly general, bi-directional, eight-bit byte oriented communications facility. The main goal is to allow a standard method of interfacing terminal devices to each other.

MikroTik RouterOS implements industry standard Telnet server. It uses port 23, which must not be disabled on the router in order to use the feature.

You can enable/disable this service or allow the use of the service to certain IP addresses.

Example

[admin@MikroTik] ip service> print detail
Flags: X - disabled, I - invalid
 0   name="telnet" port=23 address=0.0.0.0/0

 1   name="ftp" port=21 address=0.0.0.0/0

 2   name="www" port=80 address=0.0.0.0/0

 3   name="hotspot" port=8088 address=0.0.0.0/0

 4   name="ssh" port=65 address=0.0.0.0/0

 5 X name="hotspot-ssl" port=443 address=0.0.0.0/0 certificate=none
[admin@MikroTik] ip service>

Telnet Client

Command name: /system telnet [IP address] [port]
