[mrtg] Re: MRTG running, but no PNG graphs

[Leonard Miller]

I finally got around to reading the rest of my e-mail and 
realized that 3 days ago, you posted the answer to a 
problem I had a couple of weeks ago and that I fixed 
yesturday and posted the solution to the group.

Forgive me if it seemed I was trying to take credit.

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. Thanks gang,
