Stop HUDSON, and list all listening ports on server using netstat. start hudson, and do same again and check whether hudson has started. Also check hudson logs for any error messages. Check $HUDSON_HOME/config.xml to ensure right port is mentioned.

Code:

netstat -an | grep LISTEN        will list all listening ports
netstat -an | grep LISTEN | grep <port>  to check specific port is listening or not.

If you do not see the port in netstat output, then the hudson is not starting. Or if you see the port listening when hudson is down, there may be another service listening on that port.
Telnet will not show much output, but if telnet is able to connect to a port, that means something is listening on that port.

Code:

$ telnet 127.0.0.1 8080
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
^]
telnet> q

Failed connection look like this
$ telnet 127.0.0.1 345
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

SYNOPSIS

       plpftp [-h] [-V] [-p [host:]port] [long-options] [ FTP-command [parameters]]

DESCRIPTION

       plpftp provides an FTP style interface for the psion. It requires the ncpd to be running already to provide access to the serial port.

       plpftp has online help. To see the available commands start the program and enter "help".

OPTIONS

       -V, --version
	      Display the version and exit

       -h, --help
	      Display a short help text and exit.

       -p, --port=[host:]port
	      Specify  the  host and port to connect to (e.g. The port where ncpd is listening on) - by default the host is 127.0.0.1 and the port
	      is looked up in /etc/services. If it is not found there, a builtin value of 7501 is used.

       FTP-command parameters
	      Allows you to specify an plpftp command on the command line. If specified, plpftp enters non interactive mode and  terminates  after
