similar to: 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

Hi ! Here's an experimental patch for openssh-2.1.1p4 to add support (to openssh client) for -R (protocol 2). So if you have access to a commercial ssh2 server (that allows port forwardings) could you test this patch. (Note the openssh server doesn't have support for -R with protocol 2 so testing with openssh server won't do much good). To test remember to use -o "Protocol

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 It will also

Hi ! I hacked together a couple of patches for Openssh 2.1.1p4 port forwarding. It is a one patch file that does the following two things: First: If the server is configured not to allow port forwardings it sends SSH_SMSG_FAILURE (protocol 1) while openssh client expects SSH_SMSG_SUCCESS. When the client gets the failure it exists with protocol error message. This patch will accept both failure

I've attached a patch to OpenSSH 3.0.2p1 that will allow the client side of local port forwarding to be bound to a single address. For my purposes, binding to 127.0.0.1 or (via GatewayPorts) all addresses would not work. I overloaded the "-b local_host" option so that it's address will be used when "-L port:remote_host:remote_port" is also specified. Today is the first

Here's another patch for people providing ssh access to restricted environments. We allow our users to use port forwarding when logging into our mail servers so that they can use it to fetch mail over an encrypted channel using clients that don't support TLS, for example fetchmail. (In fact, fetchmail has built-in ssh support.) However we don't want them connecting to other places

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. There was an

The patch below implements a couple of features which are useful in an environment where users do not have a regular shell login. It allows you to selectively disable certain features on a system-wide level for users with a certain shell; it also allows you to control and audit TCP forwarding in more detail. Our system is an email server with a menu for the login shell; we selectively allow port

Hi, the attached patch implements adding and canceling of remote port forwardings by communicating with a running ssh client via a control socket. Thus, one can do this: ssh -MNfS ~/.ssh/ctl remotehost and then: ssh -S ~/.ssh/ctl -O add-rforward 2000:forward:80 localhost to add a new remote forwarding or ssh -S ~/.ssh/ctl -O cancel-rforward localhost:2000 localhost to remove it. The

Attached is a patch to allow a user to turn on TCP keepalives for port forwarded connections. It's mainly useful when the connections to the ssh listener are coming from many different boxes, some of which crash, leaving the service on the other side of the port forwarder waiting on connections indefinitely. It creates a new option named "KeepAliveForward" to control this behavior.

I have the following line in the sshd_config file: GatewayPorts no If I launch the ssh client as this: ssh -l user host -R 9000:otherHost:25 the port forwarding is successful! :-( As you can see, the 'netstat -na' command shows the Secure Shell daemon listening to the port 9000.

Hi there, I'm developing ssh client in pure java and, recently, I'm trying to improve the port forwarding support on that stuff. However, it seems to me that sshd of OpenSSH has not supported 'cancel-tcpip-forward' request. http://www.ietf.org/internet-drafts/draft-ietf-secsh-connect-17.txt says that | A port forwarding can be cancelled with the following message. |

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm having a problem with OpenSSH_4.0p1 when trying to do remote port forwards to a server running SSH Secure Shell 2.4.0. The problem appears to be that 2.4.0 chokes on bind addresses that aren't numeric addresses, such as "localhost" and "". The following commands are failing for me from the 4.0p1 client to the 2.4.0

Hi. Attached is a patch that introduces a new escape character (~c) that opens a command line. From the command line, a command of the form: -L port:host:hostport can be entered, which will forward the local port, as if the same option has been provided on the command line. I attempted to allow remote port forwards to be specified similarly, but the server disconnects with a protocol error

Hi, sorry if it is the wrong approuch to suggest improvments to OpenSSH, but here comes my suggestion: I recently stumbled upon the scponly shell which in it's chroot:ed form is an ideal solution when you want to share some files with people you trust more or less. The problem is, if you use the scponlyc as shell, port forwarding is still allowed. This can of course be dissallowed in
