tls - Enable/disable TLS support on the TELNET client

&pagelevel(5)&pagelevel

With tls you can enable and disable TLS security on the TELNET client. If TLS support is enabled, negotiation of the arrangements for authentication is handled by TLS to relieve the load on TELNET.

Alternatively you can also specify the settings of the tls command using the START-TLS option (-Z tls-required, see "START-TLS option" and "-Z tls-required - Enable/disable TLS security on the TELNET client"). You can specify the settings required for TLS operation using the -Z options. The description of the -Z options starts on "-Z CertificateFile - Specify file with X.509 client certificates".

The settings of the tls command become effective in the next TELNET session.
