[FreeNX-kNX] kNX behind a firewall (only port 22 open) unusable?

[LROUFAIL at nc.rr.com]

It looks it installs and runs fine.

based on the output it looks like you just need to add the password to your config file.  It should fail a lot more gracefully than it does!

Maybe I will work on that for the next version.  Also, now nomachine has released the encryption routine they use in the config file, so someone could create a patch to use the config file without modifications.

These instructions are on the website:

There are a couple of changes you have to make to the configuration file to make it work. I could not get the NX Client to generate the password that the server expects, so I had to create the nxpassgen utility to generate it. Just execute the utility. It will ask for the NX username and password. In the configuration file, in the Login group, add an entry for the password. It should look like this:

<group name="Login" >
   <option key="Password" value="password from nxpassgen" />
   <option key="User" value="the user" />
</group>

Try that and let me know if it helps.
