NSClient++ Help (#1) - NSClient++ via NSCA to Icinga not working (#806) - Message List

Hi all,

Firstly, thank everyone who works on this project, I've gotten quite far into setting up an open source monitoring system using the documentation that exists, and for that I am thankful.

I have Icinga 1.3 on my debian 6 server, successfully monitoring a number of debian and windows machines, including successfully using NSClient++.

My issue is that while I can monitor a remote windows machine using NSClient++ using active checks from the Icinga server, I cannot get passive checks working from NSClient++ using the NSCA plugin to Icinga.

I just keep getting this error on the server:

Jun 17 17:40:17 palante2 nsca[26316]: Dropping packet with invalid CRC32 - possibly due to client using wrong password or crypto algorithm?

I have tried different versions of NSClient++, (0.3.6, 0.3.8, and 0.3.9rc1 and rc2), and I have tried changing the password and the encryption (blowfish, XOR, RIJNDAEL-128, and no encryption).

Same error.

I have checked that the encryption libraries were installed. I have another debian 6 server using send_nsca sucessfully sending encrypted results to my Icinga server, so I know that the encryption protocols aren't completely broken.

I have reached the limit of my knowledge, and I hope someone can help.

Thanks,

-mk
