Error following the Remote Backup guide

Hello,

I'm trying to remote backup a pfSense 2.4.4 following the guide on de documentation:

https://docs.netgate.com/pfsense/en/latest/backup/remote-config-backup.html

The first two steps work fine:

# wget -qO- --keep-session-cookies --save-cookies cookies.txt --no-check-certificate https://myfw.mydomain/diag_backup.php | grep "name='__csrf_magic'" | sed 's/.*value="\(.*\)".*/\1/' > csrf.txt

$ cat cookies.txt 
# HTTP cookie file.
# Generated by Wget on 2019-11-20 09:58:59.
# Edit at your own risk.

myfw.mydomain	FALSE	/	TRUE	0	PHPSESSID	f5791c7d22568740ad597f797f70e8eb

$ cat csrf.txt 
sid:3717d998386ccfd0a20ff2aa0589787f8c0e4c07,1574240879;ip:f5a41dfca9d4b1487a651b2938485ff75253820a,1574240879

# wget -qO- --keep-session-cookies --load-cookies cookies.txt --save-cookies cookies.txt --no-check-certificate --post-data "login=Login&usernamefld=user1&password1fld=pfsense&__csrf_magic=$(cat csrf.txt)" https://myfw.mydomain/diag_backup.php | grep "name='__csrf_magic'" | sed 's/.*value="\(.*\)".*/\1/' > csrf2.txt

# cat csrf2.txt
sid:4e61875a4f78a3978928ad56c81cec2d789fd7fc,1574240918

But the third one doesn't:

# wget --keep-session-cookies --load-cookies cookies.txt --no-check-certificate --post-data "download=download&donotbackuprrd=yes&__csrf_magic=$(head -n 1 csrf2.txt)" https://myfw.mydomain/diag_backup.php -O config-router-`date +%Y%m%d%H%M%S`.xml

# cat config-router-*.xml

I just follow the guide step by step, is it update to work with the current release? I'm doing something wrong?

Thanks,

That method does work with the current release, I test it periodically and update the docs when things change.

Do you see a message in the logs after step 2 saying that it logged in successfully, or that it failed? You wouldn't see that in the command line output.

You are right, it works fine. I lost something when convert the multi-line command to one line.

Thanks,
