    Two Linux Mint 19.3 hosted systems running free NoMachine version 7.6.2.

    • Host-A connects to Host-B but NoMachine shows the wrong host name for Host-B.
    • Host-B connects to Host-A where NoMachine shows the correct host name for Host-A.
    • Host-A can successfully ping Host-B with the latter’s correct host name.
    • Nslookup on Host-A for the Host-B ip address shows the correct host name for Host-B.
    • The dnsmasq server (pi 4) shows that the Host-B wrong name is set correctly for another system with a different IP address than Host-B.
    • I’ve checked both systems with hostnamectl and both /etc/hosts where wrong Host-B name is not present.

    How to diagnose this? I am stumped.

    Hi, can you show me exactly where NoMachine is showing the wrong hostname? Attach the screenshots to your reply.

    Screenshot attached from Host A. W7lansvr and Win7nuc are Windows 7 VM’s running under Linux.

    Host B shows as FileSvr but should show as Lansvr.

    Can you check what the uname -n command shows on that “Host-B” machine? On NoMachine player you should see exactly the same hostname.

    uname -n on Host-B shows the name as LANSvr which is correct.

    I had previously scanned Host-B but you prompted me to check it again and I found in the Home/.nx directory references to FileSvr for the local system. So I used Synaptic to remove NoMachine and deleted the .nx from Home and then reinstalled NoMachine.

    Now all is working correctly. I must have made a mistake somewhere along the line.

    Thanks for pushing me over the line to get my mistake fixed.

    Thanks for letting us know.
    It’s not necessary to remove NoMachine. Network broadcasting informations are cached in ~/.nx/cache folder – to clear remove correct .nxs file or remove all files from that directory.
