Well, not musch to see here...yet.
I use Linux AKA GNU/Linux, which I recommend for anyone who's interested in a "*nix" system-it works with more hardware than BSD, and is free (as in speech, and usually as in beer)--a major advantage over Solaris, OSX, Irix, Unixware/Openserver/UNIX/XENIX, AIX, and so on.
To connect to SDF, several commands will work. Try
telnet
busybox telnet
ssh
dbclient
