Description Kees de Jong 2023-01-26 08:53:02 UTC 
Description of problem:
When using `ssh localhost -o "SessionType none"` I can connect just fine but cannot kill the process with ctrl+c. However, when using `ssh localhost -N`, I can use ctrl+c to kill the process.


Version-Release number of selected component (if applicable):
openssh-8.8p1-7.fc37.x86_64

Additional info:
Someone else tested it on Ubuntu using version 8.9, he couldn't reproduce it. So maybe an update of OpenSSH to 8.9 or newer works.
Comment 1 Dmitry Belyavskiy 2023-02-07 12:16:34 UTC 
Could you please try packages from rawhide (OpenSSH 9.0+)?
Comment 2 Kees de Jong 2023-02-08 08:13:39 UTC 
I've done the following.

* dnf in fedora-repos-rawhide
* sudo dnf --disablerepo=* --enablerepo=rawhide --releasever=38 update openssh
* systemctl restart sshd
* ssh localhost -o "SessionType none"

And now I can properly kill the SSH session. That version also fixes it.

* After that I rolled back with `dnf history undo last`
