Hello everyone,
I recently installed NoMachine Linux 5.1.26 (free version) on a PC running Xubuntu 14.04.4 LTS kernel: 3.13.0-87-generic. The hostname and username for that machine were both: 437 and after the NoMachine installation was finished I then made a clone image of that machine using Clonezilla. I then proceeded to clone that image on another PC but this time I changed the username and hostname to: 438 (changed IP as well). NoMachine appears to be working okay on 438 and I can create a “New Connection” and connect to it that way but when I use my NoMachine client on a third machine and “Browse Connections” I only see 437. Do I need to change some hostname files specific to the NoMachine installation in order for 438 to appear under “Browse Connections” or is it something else?
For every installation there should be another UUID: you’ve cloned the machine with an already installed NoMachine with known UUID, thats why the machine isn’t visible. You can fix this by changing UUID by hand:
– edit uuid, and change value inside (
sudo vim /usr/NX/etc/uuid)
– edit nodes.db and enter already changed UUID (sudo vim /usr/NX/etc/nodes.db)
– restart nxserver (sudo /usr/NX/bin/nxserver --restart)Thank you very much as this seems to have worked perfectly! Do you see any problem in using: uuidgen to generate entirely new uuid’s and adding them to these two files? I would like to use uuidgen in a script to automate task.
Yes you can, but we would prefer to use commands as root:
NX_SYSTEM=”/usr/NX” LD_LIBRARY_PATH=”/usr/NX/lib:$LD_LIBRARY_PATH” /usr/NX/bin/nxkeygen -u > /usr/NX/etc/uuid
sed -i “s/\(^.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*\),.*,/\1,$(cat /usr/NX/etc/uuid),/” /usr/NX/etc/nodes.db
/usr/NX/bin/nxserver –restart
