[smokeping-users] [BUG] setting umask for new RRD files

Tobias, thank you for your support so far!

I agree with Alex that Smokeping should not interfere with the umask
settings at all if it's not customizable. I believe the default umask
setting is 0007 which should already allow sufficient rights to the
files. But maybe a umask setting 0002 would be best as a compromise.

It's not always possible or desirable to use suEXEC.


Met vriendelijke groet,
Kind regards,

That solution is not very unix-like, those users should have set the umask 
less restrictive before starting smokeping. Even then, the currently forced 
umask of 022 is very restrictive, those users had it even more restrictive?

For me a umask of 002 would solve the issue, does it for you? That would be 
the quickest fix. A bit more cumbersome, but cleaner, would be to remove the 
umask call or make it configurable.
