Code:

netstat -a

will show you the currnet status of all ports.

Code:

watch -n s netstat -a

will do the same, but update once every s seconds

You can create a user using the adduser command; try

Code:

man adduser

If you want to create lots of users at once, then you still have to get their usernames from somewhere. The following Perl script:

Code:

#!/usr/bin/perl
foreach (<>) {
  system("adduser $_");
}

will create users, taking the usernames from standard input.

Run the script as it is. You can then type in the usernames, one per line. Press Ctrl+D (end of file) when done.

Alternativly, create a text file (say users.txt) containing each name, one per line, and pipe it into standard input:

Code:

./users.pl < users.txt
