The simplest way to access the nx system is to open https://nx.reading.ac.uk:4443 in a web browser. There are some things such as mapping drives which does not work with the nxwebplayer but you can still drag and drop files on to the desktop and use the NX file transfer. Note there is a keyboard mapping issue with safari but chrome works. It is also possible to use the web url to connect to a number of pre-configured custom configurations. When you connect to one of these the you may be shown a list of existing session if you already have an existing full desktop or custom session.

|Mate Terminal||Mate terminal without any desktop|

There are a number of ways to connect using the NX client from off campus. The easiest is to use a Pulse Secure connection from https://webvpn.reading.ac.uk. This will give you a network connection through the University firewall so you can connect to NX in the usual way.
It is possible to connect to NX by creating a tunnel through act-ssh. Use the following command to create a tunnel from a port on the localhost (4040 in the case below) to the port 4000 on nx.rdg.ac.uk
ssh -f <username>@act-ssh.reading.ac.uk -L 4040:nx.rdg.ac.uk:4000 -N
The port number 4040 here is used as an example and the NX service is already running on port 4000, but you can use any free port.
You can check tunnel is listening on the localhost using the command
$ netstat -an | grep 4040
tcp 0 0 127.0.0.1:4040 0.0.0.0:* LISTEN
tcp6 0 0 ::1:4040 :::* LISTE$
Now in the NX client create a connection to localhost on port 4040 or the port you have chosen to use. Mobaxterm users can setup the tunnel as follows:
Then create a NX connection to localhost on port 4040 or your chosen port:
