All, When trying to use the "radauth" tool from nagios to monitor freeradius, I get the following in the freeradius log:

Error: WARNING: Malformed RADIUS packet from host ... too long (length 18432 > maximum 4096)

radtest seems to be ok. has anyone else experienced this or knows what is wrong?

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?)
