[Nagiosplug-devel] check_radius not 64bit safe

[Folkert van Heusden]

Hi,

When I compile the nagios plugins set with 64 bit enabled, the
check_radius plugin failes: authentications always return "auth failed".
Using tcpdump I found the following:

as you can see, some fields have invalid lengths (8 -indicating a 64bit int- instead of 4 bytes).
Compling the plugin in 32-bit mode (-m32) makes it work correctly.
