Bug ID: 3704
Summary: Implement an interface to capture port number of
random remote port forwarding -R 0:localhost:22
Product: Portable OpenSSH
Version: 9.7p1
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5
Component: sshd
Assignee: unassigned-bugs at mindrot.org
Reporter: umut at tezduyar.com
I am exposing IoT devices SSH interface to the cloud. The IoT devices
set up the port forwarding with -R 0:localhost:22. The random port
number is picked by the sshd and is sent to the client on the TTY. Then
my clients are sending the port number to the server to keep track of
active sessions.
Here I rely on client doing the right thing and reporting the correct
allocated port number to the server.
I would like to request a feature to have an interface on the sshd to
capture the allocated port number for a given key/fingerprint
