Package: nsca
Version: nsca 2.7.2 does not recognize packages from nsca-client 2.9.1
Severity: normal
Dear Maintainer,
Using encryption/decryption method 16 (RIJNDAEL-256), same /etc/send_nsca.cfg
file.
nsca from squeeze / nsca-client from testing:
Apr 24 19:50:35 monitor nsca[16135]: Connection from XX.XX.XX.XX port 10630
Apr 24 19:50:35 monitor nsca[16135]: Handling the connection...
Apr 24 19:50:36 monitor nsca[16135]: Dropping packet with invalid CRC32 -
possibly due to client using wrong password or crypto algorithm?
nsca from squeeze / nsca-client from squeeze:
Apr 24 19:55:10 monitor nsca[16891]: Connection from XX.XX.XX.XX port 19846
Apr 24 19:55:10 monitor nsca[16891]: Handling the connection...
Apr 24 19:55:11 monitor nsca[16891]: SERVICE CHECK -> Host Name: 'servername',
Service Description: 'Disk usage in percent', Return Code: '0', Output: 'OKs: /run

Service Description: '5 min Load average', Return Code: '0', Output: 'OKs: load is
0.12.'

upstream broke that. (even if they said they fixed it).
it could be that it works vice versa - putting a 2.9 server with 2.7
clients. but from what i've heard, that does not work either.
there seem to be more bugs in 2.9 itsself as well - see here
http://www.nagios-portal.org/wbb/index.php?page=Thread&threadID=25672
problem is still the static packet size. they changed 512 -> 4096 bytes,
which broke everything. then they put up a patch which should have added
backwards compatibility for old_clients (like nsclient++ as well) and
new_server
http://nagios.svn.sourceforge.net/viewvc/nagios?view=revision&revision=1875
more or less, a different approach on the packet size - like the
multipacket patch from opsview for nrpe - could work better in this
regard. see here for some todos - https://dev.icinga.org/issues/2467
