Where can I get free telnet?

In environments where security is important, such as on the public Internet, TELNET should not be used. TELNET sessions are unencrypted. This means that anybody who has access to any router, switch, or gateway located on the network between the two hosts where telnet is being used can intercept the TELNET packets passing by and easily obtain login and password information (and whatever else is typed) with any of several common utilities like tcpdump and Wireshark.
