Final Steps For NXServer Setup
Port Ranges in the default NX Server configuration
|NX proxy port||5000 - 5200 *|
|X11 port||7000 - 7200 *|
|NX CUPS service port||3000 - 3200|
|NX SMB/CIFS share service port||4000 - 4200|
|NX Media service port||8000 - 8200|
|NX X11 auxiliary channel port||9000 - 9200|
To use rdesktop RDP for Windows connections, open port 3389
The posts with asterisks are required, the rest are optional depending on what optional services you actually want to run. Open at least those asterisk ports on your server and any external firewall. If you want more services, open the corresponding ports.
With respect to printing, I generally would be working on a document via remote desktop, and I can print from it on the server without opening any new ports, if I give the print command on the remote desktop from within an application, it'll do that. If I need to print a server document on the client, I'll grab the file and open it locally in Open Office and print... or send it as a fax to a fax machine that's physically accessible to me. See comments on file transfers below.
For more specific information, go to NX Server Administrator's Guide, chapter 13.
File transfers between NX Server server and nxclientSAMBA is supported, you'll need to set this up on the host and client and open the corresponding ports. SAMBA setup is beyond the scope of this document. While I have SAMBA set up on my home LAN, I'd rather leave the firewall ports closed and transfer files to/from client/server via a web-based "large file attachments" service like yousendit to make your files up to 2G in size available to client or server. SAMBA requires no special setup for NX Server, other than making sure the SAMBA ports used by Observer for encrypted file transmission (see firewall setup) are available from outside your computer or LAN.
Multimedia in NX ServerThe only sound that can be remoted from the server is via the obsolete ESD audio server rather than the ALSA that's much more normal for modern Linux distributions. Since ESD does not work from within my current Debian/Lenny setup, I can't comment on how well this works. Hopefully, Nomachines will fix this problem in future releases. If this is important to you, here are setup instructions that will work with some multimedia programs, xmms for instance.
I recommend not bothering with remote desktop multimedia unless and until they get around to supporting ALSA by default. If you want to run multimedia on your client machine, grab the files on the server and run them on the client. The other upside of this is that you don't have to open the 5000-5200 port range in your firewall which NX Server defaults to.
