perfSONAR User Q&A and Other Discussion

[Winnie Lacesso <>]

Thank you very kindly Joe!

The listings you sent look same here. 

I forgot to ask what are permissions on /var/log/perfsonar itself, but 
think have figured it out. 

Just recreating /var/log/perfsonar & chown perfsonar:perfsonar makes

drwx------ 3 perfsonar perfsonar 4096 Aug 26 11:06 /var/log/perfsonar/

/var/log/httpd/error_log full of permission denied:

[Tue Aug 25 15:24:00 2015] [error] [client 128.142.136.248] Cannot write 
to '/var/log/perfsonar/web_admin/web_admin.log': Permission denied 

/var/log/httpd/access_log shows query status 500 (Internal Server Error):

129.79.53.161 - - [26/Aug/2015:11:06:02 +0100] "GET /toolkit/?format=json

Did chmod go+rx /var/log/perfsonar, then check again:

 tail -400 a*log | grep -v POST | tail -4

Notice 500 changes to 200! And I can now get to the toolkit web page too.

So that was it - needed to chown go+rx /var/log/perfsonar

Thanks VERY much for everyone's help.

Winnie L / relieved!
