At the dawn of MUDs encryption wasn't widely available. Telnet was the protocol of choice and everything (including sending your password to log in!) was sent over the Internet unprotected.

Since then the Internet and privacy expectations have evolved and encryption is the norm. You may already be used to visiting websites that use https: instead of http:.

Dune too has evolved and now supports connecting over a transport layer security (TLS) protected port (6788). This port uses the same technology as HTTPS to let you connect to Dune with encryption to protect your password and other data and should be preferred where possible over the legacy telnet port (6789).

Not every MUD client supports connecting with TLS. Here is a list of clients we know work, and information on how to configure them correctly.

• Mudlet - how to connect securely.
• TinTn++ - how to connect securely.

These MUD clients are known to only work with Telnet. We do not recommend using them for this reason.

• CMud and Zmud
• TinyFugue (without patches)
