'man telnet' -- In your telnet client:
^]mode line^M
What is slow about ftp ? You connect quickly, but then it sits there for
some trying before it allows you to login ? That is likely to do with
either:
1> name resolution. When you connect to you linux machine, if you are
using the tcpd (check /etc/inetd.conf) then it will attempt to
lookup your hostname and check whether you are allowed to connect
to that service (ref: NET-3-HOWTO Security section).
2> authd, your tcpd may be configured to authenticate you as a user.
it does this by querying the authorisation daemon on your machine
to confirm exactly who you are. This takes time, especially over
a radio link.
While tcpd provides some useful security and logging features, in
an amateur radio environment it is probably best to not use it.
