NRPE in AIX5L...?

[Alexander Harvey]

Hi,

I found some more information:

The following message gets written to syslog:

/var/log/daemon:Jul 14 16:20:09 ausyd-dw01 daemon:err|error nrpe[876772]:
Error: Request packet had invalid CRC32.
/var/log/daemon:Jul 14 16:20:09 ausyd-dw01 daemon:err|error nrpe[876772]:
Client request was invalid, bailing out...

I see this happens in the following code fragment:

        /***** DECRYPT REQUEST ******/


        /* check the crc 32 value */
        packet_crc32=ntohl(pkt->crc32_value);
        pkt->crc32_value=0L;
        calculated_crc32=calculate_crc32((char *)pkt,sizeof(packet));
        if(packet_crc32!=calculated_crc32){
                syslog(LOG_ERR,"Error: Request packet had invalid CRC32.");
                return ERROR;
                }

Anyone have any idea why this would happen? (My configure options etc were
given in previous post).

Thanks,
Alex
