We have developed a patch that enables changing the SSH window size using the tcp window size as the source. This allows SSH to obtain maximum use of the bandwidth on high BDP links. We also have a page that describes the changes and performance. http://www.psc.edu/~rapier/hpn-ssh/ The patch against CVS is included here. Common subdirectories: src/usr.bin/ssh/CVS and ssh/CVS diff -u

As before, it is described on our website. This should apply fairly cleanly to both portable and openbsd ssh. http://www.psc.edu/networking/hpn-ssh/ Only in openssh-3.8.1p1-dynwindow: Makefile diff -u openssh-3.8.1p1/buffer.c openssh-3.8.1p1-dynwindow/buffer.c --- openssh-3.8.1p1/buffer.c 2003-11-21 07:56:47.000000000 -0500 +++ openssh-3.8.1p1-dynwindow/buffer.c 2004-07-12 07:49:29.000000000

I am utilizing an openssh tunnel between two Linux boxes. On the client box I issue the following commands to set up the tunnel; - ssh -w0:0 root at x.x.x.x -v where x.x.x.x is the IP address of the Linux system running sshd - ip addr add 10.0.5.1/32 peer 10.0.5.2 dev tun0 - ip link set tun0 up On the box running sshd I issue the following commands: - ip addr add 10.0.5.2/32 peer 10.0.5.1 dev

Recently I updated to Hardy Heron(Ubuntu beta) and with it cam openssh-client 4.7p1. In my environment we have alot of Extreme(www.extremenetworks.com) switch devices which we access via ssh. 4.7p1 would no longer allow me to connect to the switches, however 4.6p1 would. The error I received was. ' channel 0: open failed: resource shortage: Channel open failed' I did some diggin and

A couple of weeks ago I made an inquiry on window computation details that has so far gone unanswered - unsurprisingly so, I now realize, for it was way too involved. Let me try again with a simplified version, in the hope that some nice OpenSSH developer could please provide an answer. What is the rationale underpinning the sending of a window adjust packet, as implemented in channels.c? Until

Hi OpenSSH developers, I am using openSSH (now 2.9.9p2, but prob occurs in 2.9p2 also) to execute commands on a remote machine which outputs data to stdout then pipes it to another invocation of ssh which connects back to the first machine in the same way, where it starts a program to read and store the output from the command on the second machine. I am using the "command" option in

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. For starters,

I am trying to make sense of the way in which OpenSSH computes window size, so far without much success :-( My understanding is that when a client specifies a window size N at the beginning of a session, it is letting the server know that it (the server) can send, on a given channel, up to N bytes worth of data that consumes window space (essentially the payload of SSH_MSG_CHANNEL_DATA and one

Hello I am attempting to build on a LynxOS platform and am using a old version of zlib and OpenSSL-0.9.6a. I get past the configure stage by ignoring the zlib version check. However, at make stage I run into the following undefineds. Any idea what may be causing this. I am using version 3.8p1 of OpenSSH. Thank you in advance for your response Amba (cd openbsd-compat && make)

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

Hello Thanks for your response. The platform is lynxos. However when I add --with-ldflags=-lcrypt I get the following error: WS5000# ./configure --with-ssl-dir=/usr/local --with-ldflags=-lcrypt checking for gcc... gcc checking for C compiler default output... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for executable suffix...

Hello , OpenSSH gurus I am writing an SSH server but I have some problems when testing with your client - I do not recieve any window adjustments. The situation is something like this - I am exchanging data and sending window adjust after every packet, but do not get any window adjust packets. I tried to lookup the place in the source - OpenSSH-2.92p2 - but didn't find it. Can you help me - I
