When I run this
./check_http -H lvl2xxxxxedu -s "Email" -f ok -I 1xxxxx4 -u '/profile' -S --sni -p 443 -a username:pass -v

I get this as the output

I do know when I login to the page the header changes to this
https://lvlxxxxxxxdu/profile/#!/ after I login

You'll always want to use -f follow so that it follows the redirects to the final page, you would only want -f ok if you are checking the redirect.

Try this one and let us know the results:

Code: Select all

./check_http -H lvl2.XXXXXXXXXedu -s "Email" -f follow -I 1X.X.X.X4 -u '/profile' -S --sni -p 443 -a username:pass -v

./check_http -H lvxxxxxxxdu -s "Email" -f follow -I 1xxxxxx4 -u '/profile' -S --sni -p 443 -a username:pass -v
bash: ./check_http: Permission denied

As the root user please try:

Code: Select all

/usr/local/nagios/libexec/check_http -H lvlxxxxdu -s "Email" -f follow -I 14x.x.x.x4 -u '/profile' -S --sni -p 443 -a username:pass -v

Thanks

Now I get this

Code: Select all

/usr/local/nagios/libexec/check_http -H lvlXXXXXX.edu -s "Email" -f follow -I 14XXXXXX54 -u '/profile' -S --sni -p 443 -a xxx:xxxx -v

- Removed identifying information but it just shows it connecting and saying ti requires javascript to display which is why the Email string is not found -

HTTP CRITICAL: HTTP/1.1 200 200 - string 'Email' not found on

when I look at in chrome and click inspect I see it
<b>Email Addresses</b>

It looks like the remote site uses javascript to display the app, check_http won't process the javascript but it is connecting properly.

Is their any plugin to do javascript ?

Posted: **Mon Feb 14, 2022 1:46 pm**

I apologize, there isn't currently an official plugin that processes javascript but I did find this 3rd party one (I haven't personally tried it) that uses Selenium that you can try:
- Please note that if you try this it is not meant to be installed on the XI server, the Selenium/Docker software should be installed on it's own separate server
