I find I like having "set-option -g mouse on" in ~/.tmux.conf so that mousewheel scrolling feels more natural (like it does in a local terminal).

This one is a little tricky - it partly depends on the default settings of the remote sshd_config for sending KeepAlive pings (changed Debian 10 to 11, e.g) and what your local vendor-compiled ssh_config defaults look like. In general, to just solve the problem add this to your macOS ~/.ssh/config at the bottom/end:

    Host *
      TCPKeepAlive yes
      ServerAliveInterval 300

TCPKeepAlive is what it sounds like, it's the L3 level tweak. ServerAliveInterval is a higher level ping-pong on the SSH session itself; kind of overkill to have both configured, but it Just Works(tm) for most people to have them set on their client. You can look these up in the man pages (ssh_config, sshd_config) and discover even more tweakable options than just these two I presented - some you can set server side, some client side, some both.

Side note: bash has an envvar `TMOUT` -- if that's set, bash will auto-logout if you idle in a shell. It's usually not set on most Linux server installs, just be aware it exists and is a thing to look for if you're debugging some day.

Thanks I'll give that a try!
