Re: {bb} messages file full of same telnetd error from bigbro

["Stephen Pesini" <stephen.pesini@villanova.edu>]

Just use telnet:s in your bb-hosts file to tell big brother not to do a
protocol handshake.
It will only test the ability to connect to the socket (port 25) and no
handshake. This usually stops the protocol errors. This also works for
things like jakarta (tomcat) listener checks, if all you need is to test
for listening socket.
