check_tcp send null byte

[Karthik Kailash]

Hi all,

I want to monitor our Flash socket policy file server.  The server expects a
string terminated in a null byte, but I can't get check_tcp to send a null
byte.

Using netcat does work, however:

perl -e 'printf "<policy-file-request/>%c",0' | nc -v <my server> 843

Here is my check_tcp call:

./check_tcp -H <my server> -p 843 -s "`perl -e 'printf
"<policy-file-request/>%c",0'`" -r crit -M crit -w 1 -c 3 -v -d 2 -e "xml"

The check_tcp doesn't print out any response from the server, which is
consistent with server behavior when it doesn't receive a null byte (if I
remove the 0 in the perl printf).

Any thoughts or ideas would be greatly appreciated.

Cheers,
Karthik
