/dev/tty: no such device or address

Latest response

Trying to bring Microstrategy IntelligenceServer up on reboot. it needs to be owned by user "mstrsys". The startup script has a variable
"MSTR_SERVICE_RUN_AS_USER" that can be set to "mstrsys". When that is set, start script does a "su mstrsys 2>/dev/tty -c " to execute the MSTR_SERVICE_START_COMMAND as user mstrsys. Startup fails with error message "/dev/tty: no such device or address". When I leave the variable "MSTR_SERVICE_RUN_AS_USER" and allow the script to run as root, it just runs the MSTR_SERVICE_START_COMMAND as root and it comes up fine. Problem is that user mstrsys can't manipulate service when it is owned by root.

I can run it fine as root from the command line as root with the MSTR_SERVICE_RUN_AS_USER set to mstrsys and it comes up owned by user mstrsys. It only fails when MSTR_SERVICE_RUN_AS_USER is set during reboot. Any ideas?

This is happening to us also in RHEL7. Any solution welcome

Did you ever resolve this issue? I ended up running a script at system boot that ran the start script as mstrsys and everything works great. Problem is that it's just an extra step. Just curious if you ever found a resolution.

Hey, look, it's the exact error I'm trying to resolve too! I might end up writing a systemd unit file to do it right.

I finally was able to get Microstrategy support to look at this. Their fix is to edit the init script and replace '2>/dev/tty' with '2>&1' on/around line 65. This did work for me, I can now run the daemon as the mstr user at boot. Hope this helps someone.

Oh, I also needed to add the mstr user to the wheel group and then run: sed -i '/pam_wheel.so\ trust\ use_uid/s/^#//' /etc/pam.d/su

This isn't great security practice, of course. But it works for us.
