Need to Connect to pfSense Console: Screen is missing

Rocky Linux Help & Support
1

I’ve normally used screen to connect to my pfSense 2100 Console on openSUSE. Switched over to using Rocky as my main Server and openSUSE as my vm server. I’ve seen in another post that Redhat has replaced screen with tmux. I don’t know how to use tmux to connect to a serial port like screen.

Can’t use Putty, it only instals via Flathub. Does anyone know how to use tmux to connect to ttyUSB0 or does Rocky have another tool I can use?

You can’t use tmux to connect to a serial console.

You have a few options:

  • minicom
  • screen (from epel)
  • putty (from epel)
[root@xmpp01 ~]# dnf list minicom putty screen

Available Packages
minicom.x86_64                        2.7.1-17.el9                        baseos
putty.x86_64                          0.81-1.el9                          epel
screen.x86_64                         4.8.0-6.el9                         epel

To enable EPEL:

% dnf install epel-release
% crb enable

And then you can install screen or putty if those are what you need.

Seriously, Thanks for that. I don’t usually need to use a serial console, but I have enough times, that I would’ve been frustrated to figure out how to do it again. I am thrilled to see minicom is still and option.
