I trust you're making notes of all the things you're doing? :) Yes, if
they're not in the places that are listed.  (Actually it's a script,
not a binary.  You wouldn't want to change anything in a binary with a
text editor, but apart from that one of the neat things about the Unix
style is that the two kinds of program are pretty much interchangeable.)

Here are the changes I did in .../bin/smokeping on a mailserver:
----------------------------------------------------------------------
mail4:/home/ged/src/net/smokeping/bin# >>> diff smokeping smokeping.dist
1c1
< #!/usr/bin/perl -w

If you aren't used to 'diff' output then better do some more reading!
It's an extremely useful tool.

That's good!

That looks like you haven't told your slaves where the fping binary is.
That might be a little wrinkle: if the fping binar(ies) on your slaves
aren't in the same location as the one on your master, you might need
to do something sneaky like create a symlink with the same path as on
the master so that the slaves can find it:

mail4:/home/ged/src/net/smokeping/bin# >>> l /usr/local/sbin/fping
-rwsr-xr-x  1 root root 52780 2008-04-24 12:46 /usr/local/sbin/fping*
mail4:/home/ged/src/net/smokeping/bin# >>> l /usr/local/bin/fping
lrwxrwxrwx  1 root root 13 2008-04-24 12:56 /usr/local/bin/fping -> ../sbin/fping*
mail4:/home/ged/src/net/smokeping/bin# >>> l /usr/bin/fping
lrwxrwxrwx  1 root root 19 2008-04-25 10:37 /usr/bin/fping -> ../local/sbin/fping*
mail4:/home/ged/src/net/smokeping/bin# >>> l /usr/sbin/fping
/usr/bin/ls: /usr/sbin/fping: No such file or directory
