I was unable to get to that FTP site without a password, but maybe it's a local problem with my network.
You can view system-wide processes using the "ps" command and a variety of options. Check out the man-page for "ps".
Examples:
# ps -ef|more
# ps -ale|more
If, instead, you want to know which TCP services are enabled, try this:
# netstat -a|grep LISTEN
This should produce a list of services for which your system will accept connections. These are primarily controlled by the /etc/inetd.conf and /etc/services files.
