kitten ssh automatically disconnects

[zzhaolei]

As shown in the figure.

Around 18:00 on January 16th, two links were opened (both logging into the same server). At around 9:30 on January 17th, it was found that kitten ssh had exited, but the ssh connection was still maintained.

ssh/config:

Host *
    ControlMaster auto
    ControlPath /tmp/ssh-%r@%h:%p
    ControlPersist yes
    Compression yes
    ServerAliveInterval 60
    ServerAliveCountMax 3
    SetEnv TERM=xterm-256color

kitten ssh server:

ssh server:

Is this as expected?

The ssh kitten does not exit automatically. And yes when it exits the connection remains, since it uses controlmasters to enable fast re-connects. The connection will be automatically closed when you wuit the host kitty instance.

I didn't explain it clearly. Now kitten ssh server will automatically exit after running for a while, but ssh server will not automatically exit

[kovidgoyal]

kitten ssh server simply calls ssh to connect, with some options to setup the controlmasters read the connection_sharing_args() function for details. I am guessing your network/ssh server is flaky and the aliveintervals are insufficient for it.

but the ssh server is not disconnected🤔

Like I said, check the options in that function and figure out which one is causing you issues.
