Idea: reverse socks proxy
Hi,
Just a usecase that I'm sure has been covered before but just in case
its not an openssh solution would be very helpful.
I was trying to install software on a server that was firewalled so no
outbound http connections would work. I was also tunnelling via
another server. Outbound ssh connections also were a convenient option.
What would have been nice would be a remote version of

-R port forwarding and remote host:port info
...The remote hostname is showing up as 'localhost'.
That's not useful.
sshd -ddd shows the following in the midst of an
incoming "ssh -R 22220:faron:22 linus". Obviously
I want to see the word 'faron' somewhere but don't.
That seems like a bug to me.

kex protocol error: type 7 seq xxx error message
Hi,
mancha and me debugged a problem with OpenSSH 7.3p1 that was reported on
the #openssh freenode channel. Symptoms were that this message was
popping on the console during a busy X11 session:
kex protocol error: type 7 seq 1234
I managed to reproduce the problem, it is related to the SSH_EXT_INFO
packet that is send by the server every time it is sending an
SSH_NEWKEYS packet, hence after

Q: how to restrict access selectively to client initiated local port forward
...t through
$hostname). But I can't figure out the exact place to insertit in the
OpenSSH source code.
Could someone point me to the source file and line that is responsible
for the server side inialization of a client local forward?
I tried connecting in serverloop.c function: static void
server_input_global_request(int type, u_int32_t seq, void *ctxt);
which by its comment says it deals with "-R" style forwarding but this
doesn't seem to be the correct place for "-L" style forwarding.
Thanks for your help,
Mike

sshd custom shell script for specifc user
Thanks Darren, the intention to do this :
allow users to access my own shell/CLI(including authentication) on port
22.
their firewall settings doesnt allow anything other than port 22, so I
would internally redirect to port 1023 when customuser is provided.
I will try enabling logs, thanks.
