HOWTO: Access pfSense filesystems remotely with scp
Accessing pfSense with scp
Files may be transferred to and from a pfSense firewall with scp, which is part of the functionality that comes with having ssh access enabled (See HOWTO enable SSH access).
When connecting with an scp client such as from a FreeBSD/Linux command line, with WinSCP, FileZilla, or even a fish URL in Konquerer, the root user must be utilized. The root user has the same password as the admin user but it is not locked into the menu for its shell.
An example: Logged into a FreeBSD machine, I want to get a copy of a file in /tmp:
myuser@somebox:~/$ scp firstname.lastname@example.org:/tmp/lan-traffic.rrd-4h.png .
