can't write to a file...
 

Hi all

I'm writing a script/plugin for Nagios for testing a WebLogic server..
I redirect some output to a file, and then i read that file to get some data, but i can't seem to write to that file with my script :s...

this is the most important code
the variables are filled in on the right way, so that's not the problem...
everytime i execute my plugin he needs to rewrite that file ('>'), but that doesn't seem to work...
to file is accessible and everything...

does anyone have a suggestion?

* EDIT *
When i execute this script through a local terminal (PuTTy), it works
but when i execute it from Nagios, it doesn't work..

solved it

appearently, when Nagios executes a script, he becomes a user, named apache (don't ask me why)
and because of that, he doesn't have enough rights to read a file...
so i changed the permissions of that file
slightly overkill, but now i'm sure..
it's only a output file, no info of interests for other people :p so it doesn't matter

thanks anyways guys :hattip:

Why not add apache to the group of the file so you at least stop world from writing. Also, is setting it to execute such a good idea?

yes, but i find it strange that he executes it as apache...
because i use some sort of software (NRPE) and i had to made a user 'Nagios', so i thought he need that user to execute plugins..

can you perhaps explain how i can add apache to that group?
i know that those permissions are not necessary, but it is only a file where nothing important gets stored in

what is your suggestion for this?

hello,

i am not really familiar with nagios but found this, it might help

"Create a new nagcmd group for allowing external commands to be submitted through the web interface. Add both the nagios user and the apache user to the group."

Have a look at the usermod command and specifically its -G option (check man page). As it is only to be read or written to, I would suggest something like 664.
This was both owner and group members can read and update the file but the world can only look at it ( which may be good for when you are using your own login :) )
You say that it holds nothing important now, but the last thing you want to o is find there is a single executable line in it at some point and someone runs the file
mistakenly.
