Running Nagios 1.2 on RH EL3 - FIXED!

[Greg Vickers]

Ahhahaha. AHHAHAAHAHA. Cue user error, aka POBKAC...

After compiling with --enable-DEBUG(0,1,2) and attaching gdb to this new 
executable I find:
(gdb) bt
#0  0x007366d6 in strncpy () from /lib/tls/libc.so.6
#1  0x08059906 in get_raw_command_line (
     cmd=0x9591300 
"check_service_cluster!CA-R203b!31!32!$SERVICESTATEID:CA-R203b-PC01:Lab 
PC available$,$SERVICESTATEID:CA-R203b-PC02:Lab PC 
available$,$SERVICESTATEID:CA-R203b-PC03:Lab PC 
available$,$SERVICESTATEID:CA-"..., raw_command=0x2d41433a <Address 
0x2d41433a out of bounds>, buffer_length=858796626) at utils.c:1277

Gee, that looks like a cluster check service command for Nagios 2.0... 
and I'm running a Nagios executable 1.2... gosh could be a buffer 
overflow! <slaps_self_with_cod>

I had converted all my config files to 2.0 and then regressed them to 
1.2 (a lot of host names had been updated) and missed the cluster check 
services... duh.

Sorry for the hundreds of emails and thanks for the replies and suggestions!
