man ssh_config is even more interesting and hidden ProxyCommand is fun

Honest question, why is ProxyCommand `fun`? What do I get out of ProxyCommand that i do not get out of setting the correct order for ProxyJump and doing an ssh finalhost -- domy --bidding?

I use ProxyCommand to run spipe tunnels for SSH.

It'll still work. OpenSSH doesn't care about output (for ~ stuff), only input, so if you type ~. it will close the connection.

It does not. open ssh linux to mac, typing ~ just types it on fish shell prompt. It works after`cat` followed by ENTER

In newer versions, it's disabled by default and you have to do something like this to enable in ~/.ssh/config:

    Host *
    EnableEscapeCommandline yes

You can get a lot more out of ProxyCommand. For example, you can run SSH over non-IP protocols, such as serial, Bluetooth RFCOMM for embedded boards, or vsock for virtual machines without networking set up at all. The latter is built into and setup up automatically by systemd:

Many Linux man pages have the thoroughness of a fortune cookie, so I can understand the skepticism. Jackpot if they're just a pointer to an 'info' page.

Do we still have those? I think it was common in late '90s, due to GNU trying to get `info` gain moment but nowadays?

Mostly just the bash builtins have (had) this problem.

Many Linux man pages have the thoroughness of a fortune cookie, so I can understand the skepticism. Jackpot if they're just a pointer to an 'info' page.

But its also true that many, many man pages have extremely valuable information that no enterprising hacker should overlook, too ..

I've been using SSH for ~15 years and never knew about these escape sequences. I'm eagerly awaiting my next hung session so that I can test `~.`. It's much nicer than my current approach of having to close that terminal window.

I last used this menu about 20 years ago when a dialup modem was the only way to roll, and have pretty much forgotten about it since the days of always-on direct to the desktop TCP/IP ..

I blew a few minds a week ago when I told my younger coworkers about man pages. I hit ‘em with the `man man` and one dude was like “whoa!”

man, cat, lynx... We're all just creatures in a vast universe
