Useful for making a CLASSPATH out of a list of JAR files, for example.

Once Enabled this command enables a trail of all processes on the system. As the name suggested auditing for Solaris machines.
BSM creates a number of files in the /etc/security directory.

Telnet will make a tcp connection to a remote ip/port to test connectivity. If it times out, it's not reaching the host (maybe the firewall is blocking it). If connection is refused, it's reaching the host, but either the service is not listening on that port, or it's locked.
