How to automatically open my tmux session on each connection?

Can I attach to my tmux when starting a SSH or Mosh session?

[carloscabanero]

For mosh connections, go to Settings > Hosts, choose your host, and scroll down to Mosh section. In the command field, put:

tmux new -A -s name -n name

In short, it will attach(-A) if the session name(-s) already exists or create a new one. It also names the first window the same as the session(-n).

For SSH connections, go to SSH Config in the same settings panel and paste this setting:

RequestTTY yes 
RemoteCommand tmux new -A -s name -n name

RequestTTY is required to run tmux command on a remote host.

End configuration should look like example below.

From this point, Blink Shell will automatically attach to the session of your choice.

Tip: It will work with any command you like, including GNU Screen.
