NRPE in AIX5L...?

[Alexander Harvey]

Hi Ton

I'd love to grant you remote access to one of my servers but then I'd
certainly be thrown from the 13th storey (or possibly into jail)! :D And
I've studied the code a bit and I'm afraid the problem's a bit beyond me at
this point; I'm not really a developer and it's been a long time since I've
done any C. Mind you, if anyone out there can give me a start, narrow the
scope, or make any debugging tests/suggestions I'd be happy to give it a
shot and send back results or any patched code I can get to work, but I
couldn't do it on my own. I haven't seen the problem in Solaris, though. The
smooth experience I've been having with Solaris & Linux was what gave me the
idea of pushing to use this on our AIX servers. I'd also be happy to help
with any other testing on the AIX servers I have here (I've found a few
other problems).

Thanks,
Alex
