Telnet Server Test Suite Data Sheet
The Telnet protocol provides bidirectional general purpose text interface, which uses TCP for transport. Telnet is an older protocol, but it is still often implemented, for example, as configuration interface on network equipment. This test suite can be used to test Telnet server implementations for security flaws and robustness problems. Please note that the sub-negotiation portions of the following specifications are implemented as anomalies only.
