This is what I get when I run the ldd

[root at nbtbigbro1 bin]# ldd hobbitgraph.cgi 
        librrd.so.2 => /usr/local/rrdtool-1.2.11/lib/librrd.so.2 
        libpng.so.2 => /usr/lib/libpng.so.2 (0x400ec000)
        libc.so.6 => /lib/i686/libc.so.6 (0x4010d000)
        libm.so.6 => /lib/i686/libm.so.6 (0x40248000)
        libz.so.1 => /usr/lib/libz.so.1 (0x4026b000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Re: [hobbit] linux version


Yes it looks like an issue with libpng. Verify this by going to your 
hobbit directory, then cd to the "bin" directory, and run the ldd command 
on hobbitgraph.cgi.  This will show all the libs that hobbitgraph expects 
to find, and if it has access to them or not.  Here is a sample output 
from my hobbit server:

# ldd hobbitgraph.cgi
        libpcre.so.0 => /lib/libpcre.so.0 (0x0098d000)
        librrd.so.2 => /usr/local/rrdtool-1.2.11/lib/librrd.so.2 
        libpng12.so.0 => /usr/lib/libpng12.so.0 (0x00be1000)
        libc.so.6 => /lib/tls/libc.so.6 (0x005cf000)
        libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x00804000)
        libz.so.1 => /usr/lib/libz.so.1 (0x00726000)
        libart_lgpl_2.so.2 => /usr/lib/libart_lgpl_2.so.2 (0x0044d000)
        libm.so.6 => /lib/tls/libm.so.6 (0x006fb000)
        /lib/ld-linux.so.2 (0x005b6000)

I'm guessing that for you libpng is missing.  If you already have it, but 
its in the wrong place, the fix can be as simple as making a symlink to 
it, or copying it to where hobbit expects it to be.  Other solutions 
include editing your /etc/ld.so.conf (run ldconfig afterwards), or 
recompiling hobbit and giving it the exact location of libpng.

The specific issue I am having is with the history graphs drawing. 
Everything else is working fine. 
see screenshot: 

They used to work, but after a reboot, they failed.  I recall having to 
manually copy ldpng somewhere, but that is it. 

I know I am in over my head with the linux piece, but it worked before, 
and I am sure it is a simple fix; I just can't figure it out. 

I have some great resources here that know linux, but they are at a loss 
with the pieces hobbit uses. 

Any suggestions for the cgi-graphing would simplify everything, as I would 
eave the current build running.

I have had a linux rh 7.3 server running, and have had issues with the 
history graphs. 
I tried to upgrade to Fedora C3, bit that looks to be missing some 
important pieces. 
What would be the recommended version of Linux to avoid all of these 

Redhat 9? 

What missing important pieces?  I have run hobbit on Redhat9, Fedora Core 
3, Fedora Core 4, Centos 3.x, Centos 4.x, and Solaris 10.

All of the installs required fulfilling various dependencies like rrdtool, 
libpng, etc. I would say the easiest install I did was on FC4...I'm not 
sure you will find an OS that will have all of hobbits dependencies 
available in the base packages branch, but with any decently new distro 
you should have pretty much everything available except rrdtool. 

If you are the kind of person who prefers to use RPMs for everything, 
check out Dags (http://dag.wieers.com/home-made/apt/packages.php), they 
have RPMs for most distros (redhat 7,9,fc1-4,EL3-4) including fping and 
rrdtool.  You can either download the rpms manually or add dag to your 
yum.conf so you can just do "yum install rrdtool" and it will 
automatically grab the dependencies too.

Note I don't recommend this method for everyone...some people are paranoid 
(rightfully so if security is a concern) and refuse to install binary 
releases and only install manually from tarballs.
