Tmux on Kenno's Open Note

warning: TERM environment variable set to 'tmux-256color'

I use ’tmux’ on anything that runs it, from FreeBSD, macOS and Linux.

On some of my Linux servers, noticeably openSUSE ones, when I connect to them via SSH, I would receive the following warning:

...
Have a lot of fun...
warning: Could not set up terminal.
warning: TERM environment variable set to 'tmux-256color'.
warning: Check that this terminal type is supported on this system.
warning: Using fallback terminal type 'ansi'.

What worse is that, when I switch to root account, the backspace key doesn’t work correctly. For example, hitting backspace will produce a space instead.

Apart from being an aparent Linux user, I’m also a fan of FreeBSD. A few years ago I challenged myself to perform all work related tasks on a FreeBSD machine for 6 months. It turned out that FreeBSD’s been working out quite well as a general usage work desktop.

Today, I’d like to share a quick solution to a small annoying issue that may or may not affect you when you’re using FreeBSD. Basically, when I ssh from my Linux machine, which uses Alacritty terminal, to the remote FreeBSD machine at work I am not able to resume my tmux session.
