perfSONAR User Q&A and Other Discussion

[Brian Candler <>]

Another permissions problem (again perfsonar 4.2 toolkit running under 
Ubuntu 18.04 in lxd container), seen in syslog:

Sep  1 01:05:03 perf1 systemd[1]: Stopping OWAMP server...

... further retries ...

In this case, I think the problem is with the file permissions, since 
rsyslogd is running as the "syslog" user not the "perfsonar" user:

# ls -l /var/log/perfsonar/owamp.log*
-rw-r--r-- 1 perfsonar perfsonar 0 Aug 31 12:29 /var/log/perfsonar/owamp.log
-rw-r--r-- 1 perfsonar perfsonar 0 Aug 31 12:27 
/var/log/perfsonar/owamp.log.old

I could chown it, but I don't know how come it was created with owner 
'perfsonar' in the first place.

Anyway, pretty minor, but I thought I'd point it out.

Regards,

Brian.
