Check http MD5 question

[benningtonr]

I am trying to implement this into nagios and not quite sure how to proceed.

Any and all help would be greatly appriciated.

$url = $argv[1];
$md5 = $argv[2]." -";

$status=0;

$md5new = `wget -q -O - "$url" | md5sum`;
$md5new= rtrim($md5new);

if (strcmp($md5new, $md5)==0) {
echo "HTTPMD5sum OK: MD5sum matches\n";
} else {
$status=2;
echo "HTTPMD5sum CRITICAL: MD5sum doesn't match: ".$md5new."\n";
}

exit($status);

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

[benningtonr]

i took the .pl extention off and it is still not seen by the ./
Yes i can see the file is there.


[root@nagios libexec]# ./check_icmp
check_icmp: No hosts to check
[root@nagios libexec]# ./check_http_md5
Extension './check_http_md5' not present.
[root@nagios libexec]#

[sreinhardt]

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 tested this script and did find a bug (missing one space), modified version is below

Code: Select all

#!/usr/bin/php -q
<?php
# ------------------------------------------------------------------
# We offer no warantee or guarantee - use this code at your own risk!
# All code is Copyright (C) 2011, Applied Trust Engineering, Inc.

$url = $argv[1];
$md5 = $argv[2]."  -";

$status=0;

$md5new = `wget -q -O - "$url" | md5sum`;
$md5new= rtrim($md5new);

if (strcmp($md5new, $md5)==0) {
echo "HTTPMD5sum OK: MD5sum matches\n";
} else {
$status=2;
echo "HTTPMD5sum CRITICAL: MD5sum doesn't match: ".$md5new."\n";
}

exit($status);

I tested this script running

Code: Select all

./check_http_md5 http://appliedtrust.com 6106a27fb2286565467e1f88c143798f

[benningtonr]

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
Could not open input file: http://appliedtrust.com
[root@nagios libexec]#

[lmiltchev]

What is the output of the following command?

Code: Select all

which md5sum

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

[lmiltchev]

Actually, I believe I know what's the issue. Since you used Notepad, most probably you have windows EOL. Open the plugin in vi:

Code: Select all

vi check_http_md5

type:

Code: Select all

:set ff=unix

hit "Enter", save and exit (:wq)

Try running the plugin again. Hope this helps.
