perfSONAR User Q&A and Other Discussion

[Aaron Brown <>]

Hey Alex,

The bwctl RPM creates a ‘bwctl’ user, and group. The RPMs then expect to 
start up as those users. I’m not sure why they weren’t created when the RPM 
was installed, but if you run the following as root, it should create the 
bwctl user:

/usr/sbin/useradd -r -s /bin/nologin -d /tmp bwctl

Cheers,
Aaron
