We have seen how we use Mac applications such as NiftyTelent or BetterTelnet PPC. To finish off this section we consider how we run simple command line Telnet clients.
On most Unix systems and DOS Prompts a telnet session can be initiated using the telnet command. Most users simply type:
telnet <remote host>
but if the user just types telnet then various options and subcommands are available which can be used to study the behaviour of the session.
Here's an exmaple of a telnet session from scitsc to ccub
bash$ telnet telnet> toggle options Will show option processing. telnet> open ccub Trying 184.108.40.206 ... Connected to ccub.wlv.ac.uk. Escape character is '^]'.
