Backup Script Says 403: Forbidden

[A Former User]

Hi all,

based on this documentation I am trying to perform my regular backups.

I just did cut&paste of the comands noted there (for 2.3.3 and later) but everytime when I run the last command I am getting an 403 error:

root@ucs:~/backup/pfsense# wget --keep-session-cookies --load-cookies cookies.txt --no-check-certificate --post-data "Submit=download&donotbackuprrd=yes&__csrf_magic=$(head -n 1 csrf2.txt)" https://pfsense:60443/diag_backup.php -O config-router-`date +%d%m%Y`.xml 
--2019-04-08 22:12:05--  https://pfsense:60443/diag_backup.php

English translation as far as needed:
WARNING: Certificate is not trusted.
WARNING: Certificate of pfsense is from an unknown issurer

Anyone having an idea why I am getting a 403 error?

I am getting an XML File and as far as I see it has content, but is it useable?

Thanks for ideas!

The client you are running wget from is warning you that the https server you're trying to talk to doesn't have a valid cert. You will need to figure out for your client how to import the pfsense certificate and CA so that these warnings stop.

Sorry, but I do not mind about the warnings. As these are only warnings an not errors I am easily going to ignore them as my pfsense indeed uses self-signed certificates. But this is not the reason for 403 which is a server message while the warnings are a client message.

I am wondering about 403- what part is not accessible and why?

Sorry, I thought the translated English was the error. Perhaps the server sends a 403 if wget does not accept its cert?

Try switching WebGUI to http mode, edit your script accordingly and see if your problem disappears.

Sorry but SSL is for sure not the reason. 403 can happen on a non-SSL connection, too.

Must be something else.

Yes, I am aware that 403 are usually for permissions issues, but would it hurt to try my test? Just taking a wild guess. Anything in the logs about your connection attempt?

Hi,

your hint regarding the logs was really good. I usually check logs at first but this time I just forgot about it.

I got this:

Apr 8 21:20:53 	php-fpm 		/diag_backup.php: webConfigurator authentication error for user 'admin' from: 192.168.9.10
Apr 8 21:20:53 	sshguard 	27528 	Attack from "192.168.9.10" on service 380 with danger 10.

For better reading I used the backslash to skip the newline sign but then I added spaces to ident which broke up the URL parameters...
In the end it was an escaping error. Instead of

login=Login&username=admin...

I send

login=Login&   username=admin...

Now fixed- thanks for the hint!

Glad to hear you got it working.
