Protocol 2 remote port forwarding
Hi all,
I'm using openssh-2.9p2 on Solaris 2.8. I can get remote port forwarding to
work using the -R flag, but only with ssh protocol 1 not ssh protocol 2.
I've read that remote forwarding protocol 2 was not supported in earlier
versions of openssh, but I'm wondering if this is still the case. Jarno
Huuskonen [Jarno.Huuskonen at uku.fi], posted a patch in 2000 to add support

remote forwarding in 2.9p2
Hi,
It looks like remote forwarding with SSH v2 is not working
on my Solaris machines (and from what I understand from the
source, it may not work elsewhere either).
When looking at channel_post_port_listener() in channels.c,
I found that nextstate was defined as :
nextstate = (c->host_port == 0) ? SSH_CHANNEL_DYNAMIC :
SSH_CHANNEL_OPENING;
And later comes the call :

[PATCH] Implement remote dynamic TCP forwarding
Hi all,
This is a client side only implementation of reversed dynamic (SOCKS) TCP
forwarding, which means it is compatible with any existing servers
have 'remote forward' capability.
To establish such forward, use "ssh -R [BIND_ADDRESS:]PORT ...".
The server will listen on that port and address and accept SOCKS
traffics.
Hope this will be useful for you.

2.9: remote port forwarding doesn't work
Hello,
I'm running OpenBSD 2.9 (-rOPENBSD_2_9) on i386. Remote port forwarding
doesn't work. Attached are 2 logs of
ssh -v -R2828:localhost:22 localhost
and
sshd -p 2222 -d
Note that server tries to forward to
Connection to port 2828 forwarding to 0.0.0.0 port 0 requested.
instead of localhost port 22 as it should.
what ssh, what sshd and /etc/sshd_config are also attached.
Thanks

Dynamic port remote listener - a BUG?
Hello,
Today I tried using "dynamically assigned" port for remote listener, by
requesting listener on port 0. This is supposed to create a listener on a
port choosen by server. Everything seemed OK (the choosen port was sent back
to client), but forwarding was refused. So I checked the source.
in channels.c, function: channel_setup_fwd_listener

Protocol 2 remote forwarding patch
Hi !
Here's a patch to add remote port forwarding support (protocol 2) for
openssh. I have tried to test that it works like it should but a more
thorough testing is needed. This patch adds both client/server support.
The patch should be applied to openssh-2.1.1p4 source tree.
Also included is a PortForwarding sshd_config option, new ./configure
option --disable-forwarding that should make it

TCP_NODELAY always set, now?
I know that there was a discussion on this about a year back, and
there is a bug 556 this week that mentions TCP_NODELAY.
However, when I use ssh through a pipe (e.g., to tunnel through an
HTTP proxy using CONNECT) I see:
getsockopt TCP_NODELAY: Socket operation on non-socket
How do I tell which end is generating this (I'm assuming the local
side, which is running through the pipe).

disable features
this (uncomplete) patch makes various features compile time
options and saves up to 24K in the resulting
ssh/sshd binaries. i don't know whether this
should be added to the CVS since it makes
the code less readable.
perhaps WITH_COMPRESSION should be added, since
it removes the dependency on libz

transferring individual files question, pull vs. push
Can't seem to find the answer anywhere...
I'm currently using an rsync script on the source box to transfer some
individual files to the destination box...all works well. The script:
rsync -e ssh \
/var/qmail/control/file1 \
/var/qmail/control/file2 \
/var/qmail/control/file3 \
/var/qmail/control/file4 \

Recommended change for the networking page in wiki
Hello all,
I was told on IRC that I should come here to discuss a recommended change
on the networking page in the wiki.
If you take a look at the "Basic Script" shown here:
http://wiki.libvirt.org/page/Networking#Forwarding_Incoming_Connections
It does two things:
1) Create a DNAT rule in the NAT table of IPTABLES
2) Create a FORWARD rule in the FILTER table of IPTABLES

Portforwarding using the control master.
Hi all,
currently I am considering writing a patch for OpenSSH that will allow
portforwarding using the control_master unix domain socket. The idea is
to introduce an extra SSHMUX command, SSHMUX_COMMAND_SOCKS, which will
then pass control to the normal socks functions used for dynamic
forwarding.
The main reason for me to write this patch are:
- some more control over who gets to connect to

SSH connection hanging on logout
I am running OpenSSH 2.9p1 on SunOS 5.7 w/4-24-2001 patch cluster.
Like many other users I am seeing the hanging session on logout
with background processes. This is a huge problem for me as
I centrally manage 50+ machines with rdist across ssh.
Instead of just complaining about the problem I thought I would
put my CS degree to use and try to track down the problem myself.

LocalForward and RemoteForward bind patch
FINALLY, it's here.
You can now tell SSH which address to bind to for every single port
forwarding option! This patch allows you to pass the following as ssh
command line options:
ssh -L 192.168.1.55:1234:localhost:80 -R ::11:22:aa:bb/80/localhost/80
etc.
Or as normal config file options:
LocalForward ::11:22:33/1234 localhost/80
RemoteForward 1.2.3.4:80 localhost:80

Preserving argument splitting with SSH
I'm using:
% ssh -V
SSH Version OpenSSH-1.2.3, protocol version 1.5.
Compiled with SSL.

Linux gellar 2.2.13 #1 SMP Wed Dec 29 14:07:41 PST 1999 i686 unknown

protocol that argument splitting is not preserved from client to server,
but instead the argument list is re-split on whitespace. E.g., from my

openssh for UWIN
I am enclosing a context diff of the changes that I made to get
openssh working on UWIN. UWIN is a UNIX operating system layer
that runs on Win32 systems. For more information on UWIN
go to http://www.research.att.com/sw/tools/uwin/.
I also ran configure using -with-cppflags=-D_BSDCOMP=2. I don't
know where that information would go with the source code.

Protocol 2 remote forwarding patch
Hi all,
I'm very new in this list, as looking for codes to plug up the lack of
functionality of "Protocol 2 Remote Forwardig".
Fortunately, I could find it in MARC's archive. Mr. Jarno Huuskonen
posted the codes in Sept, last year, and I tried applying it to my
FreeBSD box environment.
I couldn't apply an original patch, of course, for incompatibility of
virsion. The
