NoMachine NX: Is server running or not?

Is it running or is it not? Only NX knows...

????????

Code:

# ./nxserver --status
NX> 900 Connecting to server ...
NX> 110 NX Server is running.
NX> 999 Bye.
# ./nxserver --stop
NX> 500 Service was already stopped.
NX> 999 Bye.
# ./nxserver --status
NX> 900 Connecting to server ...
NX> 110 NX Server is running.
NX> 999 Bye.
# ./nxserver --start
NX> 122 Service started.
NX> 999 Bye.
# ./nxserver --status
NX> 900 Connecting to server ...
NX> 110 NX Server is running.
NX> 999 Bye.
# ./nxserver --stop
NX> 123 Service stopped.
NX> 153 Stopping NX server monitor.
NX> 153 NX server monitor already stopped.
NX> 999 Bye.
# ./nxserver --status
NX> 900 Connecting to server ...
NX> 110 NX Server is running.
NX> 999 Bye.

Status says its running. Why don't you trust it? Within ps output it only show when theres is a connection.

Why SHOULD I trust it? Look at the commandline captures in my initial post. If you don't see the discrepancies in what is output by the program, look again, more closely. One minute it tells you it's running, so you stop it, and it comes back and says it was already stopped (after just having told you it was running!)

Obviously the software is confused about its status. So what you do is just ignore what it thinks, and go forward based one what you believe is true, not what it tells you. It can't keep its story straight.

Did not completely grasp the whole rundown. Sorry for that. And your totaly right nx is not sure about is state. I tried similar like you did on a host with 3.5 installed.

Code:

strace -e open nxserver --status
...
NX> 900 Connecting to server ...
--- SIGCHLD (Child exited) @ 0 (0) ---
NX> 110 NX Server is running.
open("/usr/NX/var/run/daemon.pid", O_RDONLY|O_LARGEFILE) = 3
NX> 110 NX Server monitor is running.
NX> 999 Bye.

I guess your /usr/NX/var/run/daemon.pid has a wrong value.
It should have the pid of the running "nxserver --start"
