I am running version 3.0.1 with plugin version 1.4.11 on a linux box.
I run this command from the command line:
/usr/local/nagios/libexec/check_http -H device.ip.com -t 20 -a :AbCdef\$\$ -u / -r 'var rfAssociated = 1'. I get back a "HTTP OK".
But when Nagios runs the command I get a "401 Unauthorized".
I have tracked the problem down to the length of the password. If I use the '-v' option on the check_http command I get 2 different Basic64 authentication keys back. When I do the command manually I get:
Authorization: Basic OkFiQ2RlZiQk
But when I add the '-v' to the Nagios output I get:
Authorization: Basic OkFiQ2RlZiQ=
Notice the difference, the '=' as compared to the 'k' at the end of the line. I ran some tests and it looks like Nagios will only except 8 characters for the password length. With the '\''s as an escape character for the $$, the password is 10 characters long. If I change the password on the device to have only 1 '$' in the password, Nagios gets the "OK".
It is not really feasible to change the passwords at this time.
So, I either need to know what source code file to look in to make this change or hopefully there is a parameter in one of the configuration files I can change.
