I also forgot to mention the other thing to check for is cgi execution
issues. Your webserver should be configured to execute cgi in the
specified hobbit-cgi directory, otherwise it can cause similar problems
to what you are seeing. I recommend checking your
/var/log/httpd/error_log and see if there are any cgi permissions
errors.<br>
<br>
My server has an /etc/httpd/conf.d/hobbit.conf, which contains all of
the directory aliases and defines permissions for the cgi directories.
You should have one as well, either there or appended to your
/etc/httpd/conf/httpd.conf file.<br>

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:<br>
<br>
<tt># ldd hobbitgraph.cgi<br>
libpcre.so.0 => /lib/libpcre.so.0 (0x0098d000)<br>
librrd.so.2 => /usr/local/rrdtool-1.2.11/lib/librrd.so.2
(0x00d35000)<br>
libpng12.so.0 => /usr/lib/libpng12.so.0 (0x00be1000)<br>
libc.so.6 => /lib/tls/libc.so.6 (0x005cf000)<br>
libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x00804000)<br>
libz.so.1 => /usr/lib/libz.so.1 (0x00726000)<br>
libart_lgpl_2.so.2 => /usr/lib/libart_lgpl_2.so.2

/lib/ld-linux.so.2 (0x005b6000)</tt><br>

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.<br>

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.<br>
<br>
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. <br>
<br>
If you are the kind of person who prefers to use RPMs for everything,
check
out Dags (</font><a
href="http://dag.wieers.com/home-made/apt/packages.php"><font
color="blue" size="3"><u>http://dag.wieers.com/home-made/apt/packages.php</u></font></a><font
size="3">),
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.<br>
<br>
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.<br>
