similar to: [Bug 1758] New: client hangs when closing a multiplexed session with \n~.

Hi, I have sshfs and ssh to my host setup to use the same socket with ControlMaster setting. Now when I try to scp a file to/from my host I see poor transfer speed. Also, a cp-ing a file to the mounted filesystem results in poor throughput. On the other hand, if I don't use the multiplexing, I get very good throughput. Now, my question is, when I multiplex, does the IPQoS get set wrongly for a

I am trying to set up port forwarding using the client of a multiplexed connection, but the client is dying. The connection paramaters I am using are as follows: for the master: /usr/bin/ssh -T -n -N -o ControlMaster=yes -o ControlPath=/var/run/autossh/control-%r@%h-%p.sock -o ConnectionAttempts=3 -o BatchMode=yes -o EscapeChar=none -o ExitOnForwardFailure=yes -o ServerAliveInterval=15 -o

Hi all, we were discussing internally how to make openssh leave open file descriptors that were open before main using LD_PRELOAD. Lately I filled upstream bugzilla [1] with proposed solution, that could be acceptable by upstream, but I'm also posting on this list to get more attention, other points of view or ideas for this case. I understand well, that closing FDs is important for

TL;DR: I expect ProxyCommand to have effect in preference to ControlPath. I've just tripped over this one. I have an ssh Host (let us call it "MAIN") with a ControlPath and with ControlMaster=no, from the .ssh/config file. I also have a shell script whose purpose is to hop to a remote host through a port forward, which uses the ProxyCommand option like this: ProxyCommand ssh

hello ssh list, long time user of openssh, but relatively new to the concept of ssh multiplexing. i'm experiencing some issues and i haven't figured out how to troubleshoot it just yet. would appreciate some help if possible. i'm using ssh as a communications mechanism to pass text file based messages between 2 hosts. There are programs on each side that send and receive these

Hello All-- First, thanks for ControlPath/ControlMaster. It's very handy, and ControlMaster=autoask is just what i wanted! I'm having difficulty with a common use case, however. I want to LocalForward on secondary connections using an already-established ControlPath. From what i can tell, the second ssh connection doesn't report any errors, but silently ignores the supplied

Is anyone aware of a method to force termination of a single channel without waiting for the associated process to complete? I have a use case where my client submits several commands to be executed over the same session at the same time on separate channels. In some cases (cough df), one or more those commands may hang indefinitely. I detect that the command is not finishing in a reasonable

I've managed to figure out a scheme using SendEnv. The way it works is that I add the following to my local .bashrc ``` export LC__LOCAL_TTY_NAME="ssh-$(basename $(tty))" ``` then on the same local machine add an entry to my .ssh/config ``` Host = remote Hostname = my.remote.host SendEnv LC__LOCAL_TTY_NAME ControlPath ~/.ssh/cm-%r@%h:%p ControlMaster auto ControlPersist
