When trying to view the Tim packet Statistics or Timlog files, the browser displays an error indicating no permission to the file e.g.
Cannot read /etc.wily/cem/tim/logs/protocolstats1/2013-08-13.csv: [Errno 13] Permission denied: '/etc.wily/cem/tim/logs/protocolstats1/2013-08-13.csv'
Inspection of the file in the file system using 'ls -al' shows that the file permissions are:
-rw-r----- 1 root root 25031 Aug 13 06:24 2013-08-13.csv
In this situation, when logged in as root, the umask is set to 0022. So, the default file creation umask for a logged in user would be okay.
However, the TIM process runs as a daemon which is not owned by any logged in user.
For daemon processes, there is another file which can be modified to set a different default umask for processes running as a daemon.
In this case, the umask had been manually modified for daemon processes as follows:
A umask of 027 results in file permissions of:
Which are readable only by the daemon process owner and users who are members of the daemon process owner's group.
There are two possible solutions for this:
Here is an example of a portion of an rc.tim file which has been modified to set a default umask to 022:
# Start/stop Tim (Transaction Impact Monitor)
# /etc/wily/cem/tim should be a symbolic link to the current # tim directory. # set umask to overwrite anything in /etc/sysconfig/init umask 022
