You will need to install the plugin to the XI box and create a command for it. See the following documentation:
http://assets.nagios.com/downloads/nagi ... ios_XI.pdf

I installed a file i created called check_http_md5.pl, but I get this when I try to test
[root@nagios libexec]# ./check_http_md5.pl
Extension './check_http_md5.pl' not present.
[root@nagios libexec]# ./check_http_md5
-bash: ./check_http_md5: No such file or directory
[root@nagios libexec]# ./check_http_md5 arg1
-bash: ./check_http_md5: No such file or directory
[root@nagios libexec]# ./check_http_md5.pl
Extension './check_http_md5.pl' not present.
[root@nagios libexec]# ./check_http_md5.pl -H
Extension '' not present.
[root@nagios libexec]# ./check_http_md5 -H localhost
-bash: ./check_http_md5: No such file or directory
[root@nagios libexec]#
the file is there when I do an ls on the directory

According the script this should be a php file, so pl would not be applicable, however either .php or no extension should be fine. Please list the directory and return the output so we can check a few things.

I copied the items into notepad, saved it with no extension and uploaded it as a plugin, then at the CLI ran the following.
[root@nagios libexec]# ./check_http_md5
http://appliedtrust.com 6106a27fb2286565467e1f88c143798f

What is the output of the following command?
Try changing the ownership of the plugin:
Code: Select all
cd /usr/local/nagios/libexec
chown root.root check_http_md5
and try running the check again.
I am not familiar with this plugin, and using the help ("-h") flag, didn't provide me with much info...
However, I was able to get:
Code: Select all
[root@testbox libexec]# wget -q -O - http://appliedtrust.com | md5sum
da95e2f28e2f6e78d5d3e4dfdbfc387b -
[root@testbox libexec]# ./check_http_md5 http://appliedtrust.com da95e2f28e2f6e78d5d3e4dfdbfc387b
HTTPMD5sum OK: MD5sum matches

Actually, I believe I know what's the issue. Since you used Notepad, most probably you have windows EOL. Open the plugin in vi:
type:
hit "Enter", save and exit (:wq)
Try running the plugin again. Hope this helps.
