nomachine has *just* made the new home version free as in beer in the last
couple of weeks. I haven't tried it because it is limited to 2 registered
users, and two concurrent users as well. That isn't enough for my needs, so
I use FreeNX.
1. You need to install FreeNX and knx ( `sudo apt-get install FreeNX knx` )
2. You should have a high port for ssh, not the default of 22. This stops
amateur ssh login attacks against you computer. NX doesn't depend on this
non-standard port, but it will use an ssh port, so it is good to set this up
now. `sudo nano /etc/ssh/ssh_cong` and `sudo nano /etc/sshd_config`. In both
those files, change the ssh from port 22 to port XXXX where XXXX is a high
number. Make sure you open port XXXX in any firewall you have!
These changes will go into effect when you reboot or ottherwise restart ssh
(don't have access to kubuntu box right now, try `sudo /etc/init.d/sshd
restart` or stop, then start.
Anyhow, you also need to make sure that /etc/nxserver/node.conf has port XXXX
as your ssh port. There are also other options in there, so read that file
to get familiar with what is possible.
3. Run `sudo nxsetup --setup-nomachine-key` Do nxsetup --help to make sure I
got that switch correct. This sets up the security with nomachines default
key, not the most secure way, but good enough for trial and experimentation.
4. Knx is a KDE nx client. I don't like it, and don't use it, but it is nice
to have installed. Download and install the Debian/Ubuntu client from
nomachine.com
5. Remember to specify your new port of XXXX in nxclient when you are making a
new connection.
`nxserevr` controls the server, so `nxserver restart`, `nxserver --list`
`nxserver --history`, `nxserver --terminate john`, etc.
HTH,
Mark
