similar to: [Patch] SSH through HTTP proxy using CONNECT

Hi, the attached patch adds support for the keywords "OpenCommand" and "CloseCommand" to ssh_config. They are commands which are executed before the connection is established (or ProxyCommand started) and after the connection has been closed (or ProxyCommand ended). this is usefull for stuff like portknocking or (that's what I wrote the patch for) talking with trapdoor2

Hi, At the n2k10 OpenBSD network hackathon, I finally got some time to clean up and rewrite the ssh(1) client multiplexing code. The attached diffs (one for portable OpenSSH, one for OpenBSD) are the result, and they need some testing. The revised multiplexing code uses a better protocol between the master and slave processes and I even bothered to write it up :) It tracks the control sockets

This allows me to set 'ControlPath ~/.ssh/sockets/%h.%p.%u' for example. Have I missed a good reason why ssh_connect finds the default port number for itself instead of just having it in options.port (like we do for the the default in options.user)? --- openssh-4.1p1/ssh.c~ 2005-06-12 09:47:18.000000000 +0100 +++ openssh-4.1p1/ssh.c 2005-06-12 09:40:53.000000000 +0100 @@ -604,6 +604,17

In the current implementation, ssh always uses the hostname supplied by the user directly for the SSHFP DNS record lookup. This causes problems when using the domain search path, e.g. I have "search example.com" in my resolv.conf and then do a "ssh host", I will connect to host.example.com, but ssh will query the DNS for an SSHFP record of "host.", not

Hi all, I'm using openssh 5.9p1 with the remote port forwarding "ssh -R 20000:localhost:22 xxx at x.x.x.x". The tunnel is set up. But when I write data to the tunnel, the ssh client failed to forward the data to the localhost. The debug is below: debug1: client_input_channel_open: ctype forwarded-tcpip rchan 2 win 131072 max 32768 debug1: client_request_forwarded_tcpip: listen

This patch allows the OpenSSH client to make connections over SCTP, and allows the OpenSSH server to listen for connections over SCTP. SCTP is a robust transport-layer protocol which supports, amongst other things, the changing of endpoint IPs without breaking the connection. To connect via SCTP, pass -H or set "ConnectViaSCTP yes". To listen via SCTP as well as TCP, set

[Please CC me, I'm not on the list] My box is on a mostly Windows-populated network. Naturally, I set up Samba and added WINS as a name resolution option. I found out that some programs now can use NetBIOS names, other can't. openssh falls into latter category :-( I found that openssh use this snippet to convert hostname to ip: if((gaierr = getaddrinfo(host, strport, &hints,

Here are the new versions of this widely used patch for OpenSSH 3.2.2p1 and 3.2.3p1. The patch avoids waiting to long when using ssh() or scp() on a down host, it is usefull when you have to update many hosts via rsync or rdist themselves relying upon ssh(). It enables a new option 'ConnectTimeout' to control exactly the timeout value, so that it can be used even on slow links. These

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

These patches implement a new mux client request to list the currently opened TCP forwardings. It also removes some todos regarding keeping the list of forwardings in the options up-to-date. Bert Wesarg (6): attach the forwarding type to struct Forward merge local and remote forward lists generate unique ids for forwardings to be used for identification remove closed forwardings from

I apologize, this patch should have been sent awhile ago. Between a lot of things that needed to be completed at work as a sysadmin for the Research Computing group at Purdue University and retiring from work after 38 years at the end of May (2012), I basically ignored it. This patch is from a clone of my workstation that I just activated at home. The patch was primarily written to fix the

Hello, I use hosts that are dual stack configured (IPv4 and IPv6) and it happens that connectivity through one or the other is broken and timeouts. In these case connection to the SSH server can take quite some time as ssh waits for the first address to timeout before trying the next. So I gave a stab at implementing RFC 8305. This patch implements part of it in sshconnect.c. * It does not do

The attached patch adds a new 'ConnectTimeout' option (man page updated in patch) to avoid wasting time when the target host is down. I needed that because I was using rsync/rdist over ssh for massive files update and the default connect() took too long for my purpose. The patch was tested on Linux only, but I used a similar one for ssh 1.2.XX on Linux, Solaris and HP-UX without

Here is a version of this widely used patch specific for OpenSSH 3.1p1, as it is still not in the main tree (perhap one day...) The patch avoids spending too much time when doing an ssh()/scp() on a down host, as it does not depend off the default TCP timeout used by connect(). Patch was tested on Linux, Solaris and HP-UX. The patch can also be found on:

In the past 2 months another change occurred in the CVS code that broke my ssh-keyscan patch. Here's an updated version that tweaks the changed name (in the Kex struct) and also causes an attempt to grab an ssh2 key from an older server (without ssh2 support) to fail earlier and without an error message (Stuart Pearlman emailed me some code for this). This patch is based on the BSD CVS

Hi, some of my maintenance scripts weren't working as expected and I finally found that this only happens if the user was mapped to a backend server reachable via IPv6: On a director: doveadm mailbox status -u username messages Junk returns Junk messages=203 (if backend is connected via IPv4) or Lookup of host ipv6addr:542 failed: ... (if backend is connected via IPv6)

Hello, My usage of ProxyCommand just calls the nc utility with various parameters. That in turn after the initial setup just copies copies the data from the network socket to stdin/stdout. This useless coping can be avoided if ssh has an option to receive the socket from the proxy command. I suppose it can improve network error reporting as ssh would talk directly to the network socket rather
