RHEL 6 No protocol specified, can't open display

I got this when I try to open nco_event in RHEL 6.3

[netcool@noi bin64]$ nco_event&
[1] 19962
[netcool@noi bin64]$ No protocol specified
Fatal Error:  /opt/IBM/tivoli/netcool/omnibus/platform/linux2x86/bin64/nco_event: can't open display

Any idea to solved that?

Solution


  • Do you use Putty & Xming to connect to this machine?
    If not, check the Xorg server on your client.
    You can also check the $DISPLAY variable
