Alex, I feel so much better knowing I'm not nuts and that my code does work.
MRTG runs fine w/o the external program interface (got it watching our router at the datacenter so we can charge customers bandwidth) I found the last newline and removed it. 0000000 2 0 0 \n 0 \n 0 \n C o p y Q u e u 0000020 e L e n g t h 0000027 The script has 777 permissions (I'll adjust these later) and I still get the same error. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alex van den Bogaerdt Sent: Tuesday, March 18, 2008 10:42 AM To: [email protected] Subject: Re: [mrtg-developers] Getting error from MRTG whenrunningexternalscript On Tue, Mar 18, 2008 at 10:26:44AM -0500, Scott S.

Looking good. But where does this final newline come from? Does your mrtg setup work if you don't use the external program interface? Can the mrtg script start your script?
