First off, running things like mrtg as root are generally bad ideas - you
should create a non-privileged user to run it.
But even root can't run a script if the execute bit isn't set on the
permissions.  try:
chmod u+x /etc/mrtg/ping.sh

I've also run into that type of error when copying scripts from windows
machines, because the first line isn't just #!/bin/sh, it's actually
#!/bin/sh\n, which is a valid filename on unix, but not at all what you
want.  If you pull up the file in vi you can see if the format is [dos].  If
so, do 
:set fileformat=unix
:wq
