I haven't seen it. I note that 18432 is hex 0x7200. I suspect that
the NAGIOS people missed a 'htons()' somewhere, and the field should be
0x0072.
Alan,
You are exactly correct. Good catch. For mailing list archives, the
simplest patch I came up with:
/* copy the first 20 bytes of the radius header. this size is static
* per RFC.
*/
radhead->rad_length = htons(radhead->rad_length);
memcpy(packet,(char *)radhead,20);
radhead->rad_length = ntohs(radhead->rad_length);
rad_length is used elsewhere, so this is done to avoid breaking anything else.
Thanks for your help! (I wonder how this always worked for xtradius
from the same machine?)
