I did a fresh compile of each portion. It think ( im not in front of the machine right now ) that I had to install 3 software packages PRIOR to installing Redhat. I remember the Libpng, and I think that GD and ZLIB were the others I installed. The Unix install directions are pretty simple and if you follow them, you *should* be producing the graphs in no time. I suspect that if your using RPM's , the path to the LIBPNG is wrong ( I'm not an RPM person so I don't know how they work )
I would really recommend reading the UNIX install directions and giving that a shot. It takes a little time to find the files you need, but the install is straight forward. But First.... Try running MRTG from within the MRTG directory. Linux doesn't search the current directory by default like Dos/Windows, so you will need to go into the MRTG directory containing the mrtg executable and do ./mrtg "your config file " ( Sans quotes ) I believe it defaults to /usr/local/mrtg-2/bin, but I could be mistaken. I had an issue were a bogus copy of mrtg was installed on a development machine and it was sym-linked in the path. Speaking of which, verify that your path contains the path to your MRTG files ( see above for default ) I would do a "locate mrtg | more" and see if there are any rogue copies floating around... I'm not a Linux expert by any means, so take my advice with the proper seasoning ( grain of salt ) Good luck and let us know how you do...

My attempt to edit /etc/profile (as per Eric) was a bust (I'm still a bit green with RedHat, so I think I did it wrong). Taking your advice I looked at my env variables and sure enough, it was still: LANG="en_US.UTF-8" ...rather than: LANG="en_US" My fix was to edit the /etc/sysconfig/i18n file and change the LANG variable there (then: source /etc/sysconfig/i18n). As you said, this removed the first block of errors. Now I'm left with only one error (which repeats several times) - no graphs yet, but considerable progress: gd-png: fatal libpng error: Invalid filter type specified gd-png error: setjmp returns error condition When you re-installed your libpng/mrtg software, were you able to install an RPM or did you compile from source?

See what your LANG is equal to. If you changed the file, but didn't log out and back in the change didn't get implemented. You can type those to commands at a command prompt to change the current running shell variables and avoid a logout/login as well.

Unfortunately the problem still persists: When I installed RedHat the dependant RPM's were already installed: gd-1.8.4-9 zlib-1.1.4-4 libpng-1.2.2-6 ...as per Eric I added: LANG='en_US' export LANG ...to my /etc/profile ...and taking Larry's advice, I went ahead and re-downloaded/installed the dependencies with a --force option: gd-1.8.4-9 zlib-1.1.4-4 libpng-1.2.2-6 Still no luck, and the same errors: Malformed UTF-8 character (unexpected continuation byte 0xa4, with no preceding start byte) at /usr/bin/../lib/mrtg2/locales_mrtg.pm line 277. (this error repeats many times with many, many different line numbers) gd-png: fatal libpng error: Invalid filter type specified gd-png error: setjmp returns error condition (this error repeats several times as well) I'm feeling rather newbish here. I have MRTG running flawlessly with an older version on another RedHat system (one that I had compiled rather than RPM'd). Unfortunately we're trying to keep this particular system loaded with 'easy' RPM's. Any other ideas?

I had the same issue and had to download all the separate libpng software, install it, then re-install MRTG. At least that's what happened with me. The good news is that after redoing the MRTG install and adding the stuff the Eric added, MRTG is running like a champ on RH8.0 Thanks Larry -----Original Message----- From: Brander, Eric [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 07, 2003 11:41 AM To: 'Grover, Ross'; [EMAIL PROTECTED] Subject: [mrtg] Re: MRTG running, but no PNG graphs LANG='en_US' export LANG Put that in your /etc/profile Eric Brander ACS Texas CHIP Account Sr. Communications Engineer - Information Systems Department 512.336.3331 [EMAIL PROTECTED] -----Original Message----- From: Grover, Ross [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 07, 2003 10:21 AM To: [EMAIL PROTECTED] Subject: [mrtg] MRTG running, but no PNG graphs I'm new to this mailing list, so I apologize if this topic has already been covered. I have looked through many FAQ's, and posts for answers to this question - I've found many others with this same issue, but no answers yet: I'm running Linux RedHat (version 8), and have installed the mrtg-2.9.25-1.7.2.i386.rpm Regarding dependencies, I have the following installed: gd-1.8.4-9 zlib-1.1.4-4 libpng-1.2.2-6 ------------------- After the install, SNMP data is collected, and everything seems to be running fine. But on the web page, no graphs are displayed. In my html directory, the .png files are seemingly created, but only 75 bytes long. Below are the errors I receive: Malformed UTF-8 character (unexpected continuation byte 0xa4, with no preceding start byte) at /usr/bin/../lib/mrtg2/locales_mrtg.pm line 277. (this error repeats many times with different line numbers) gd-png: fatal libpng error: Invalid filter type specified gd-png error: setjmp returns error condition (this error repeats several times as well) Any help would be greatly appreciated.
