Hi list,
I have rewritten the pure-ftpd resurce agent to a proftpd resource agent. In my
first tests it runs well. In one week the system will be productive, and if I
find any bug until then, I will post the diffs here.
Actually it does the same thing as the pure-ftpd script, except monitoring. It
is possible to configure in cib.xml an OCF_CHECK_LEVEL greater zero. The script
will not check anymore for the pid, but it will perform a login to the ftp
server on localhost with curl.
So far as I can see the pure-ftpd script was published under the GPL, and I
would like to contribute that script under the GPL as well. Could anyone commit
that code, please?
One Question is left:
<actions>
...
<action name="monitor" depth="10" timeout="20s" interval="60s" start-delay="1s"
/>
...
</actions>
What I have to write here? Any docs?

Hi List,
Is there somewhere already in the sources a ocf script for proftpd
available?
If not I will rewrite the pure-ftpd script from:

Thanks,
