# /usr/local/nagios/libexec/check_heartbleed.py -h
usage: check_heartbleed.py server [options]
Test for SSL heartbeat vulnerability (CVE-2014-0160)
options:
-h, --help show this help message and exit
-H HOST, --host=HOST Host to connect to (default: 127.0.0.1)
-p PORT, --port=PORT TCP port to test (default: 443)
-v VERSION, --version=VERSION
TLS or SSL version to test [TLSv1.0(0), TLSv1.1(1),
TLSv1.2(2), or SSLv3.0(3)] (default: all)
-u, --udp Use TCP or UDP protocols, no arguments needed. This
does not work presently, keep to TCP. (default: TCP)
-t TIMEOUT, --timeout=TIMEOUT
Plugin timeout length (default: 10)
-V, --verbose Print verbose output, including hexdumps of packets.
Example Usage:
# ./check_heartbleed.py -H yahoo.com -p 443 -v 1

# echo $?
0
# ./check_heartbleed.py -H vulnerable.site.com -p 443 -v 1
CRITICAL: vulnerable.site.com TLSv1.0 is vulnerable
# echo $?
2
# ./check_heartbleed.py -H vulnerable.site.com

Hey,
The plugin works great for some hosts, but is failing for a fairly large number, not sure if this is an issue at my side but I don't think so -
[root@host scripts]# ./check_heartbleed.py -H www.google.com -p 443
OK: Server www.google.com TLSv1.0 is not vulnerable. TLSv1.1 is not vulnerable. TLSv1.2 is not vulnerable. SSLv3.0 is not vulnerable.
[root@host scripts]# ./check_heartbleed.py -H www.test.com -p 443
UNKNOWN: Server www.test.com closed connection without sending Server Hello.
Any thoughts?

In Fortigate devices with FortiOS affected by Heartbleed (FGxxx-5.00-FW-build208-130603), plugin returns OK instead CRITICAL.
When we check this devices with NMAP and ssl-heartbleed.nse script, the result is VULNERABLE.
When we check this devices with NMAP and ssl-heartbleed.nse script, the result is VULNERABLE.
As of 14/4/14 (v0.3), All known issues with python 2.4+ should be resolved. There has been a -H flag per standard nagios plugins, and additional error handling. Please try it again and let us know if issues persist.

Below is the steps I followed:
1. downloaded “Check_heartbleed.txt” to “check_heartbleed.py”
2. moved to “/usr/local/nagios/libexec/”
3. chmod –R 777 check_heartbleed.py
I am getting below error if I execute the script.. any clue on this?
[root@localhost libexec]# ./check_heartbleed.py 10.1.71.49 -p 443
Traceback (most recent call last):
File "./check_heartbleed.py", line 151, in

s.connect((args[0], opts.port))
