Hi, The default value for the option CanonicalizeFallbackLocal. In the manual, The default value "no". CanonicalizeFallbackLocal Specifies whether to fail with an error when hostname canonical- ization fails. The default, ?no?, will attempt to look up the unqualified hostname using the system resolver?s search rules. A value

Dear developers, The ProxyJump feature is nowadays implemented on the basis of a TCP port forwarding on the jumping host, isn't it? As a result, this is affected by a AllowTcpForwarding=no configuration on the jumping host. So, may I suggest a variant based on Unix sockets (such as -L or -R does). Nice idea, isn't it? Any volunteer to implement this? Best regards Christophe

Hi ML members, is there a reason, why ssh-keyscan does not use Host definitions from .ssh/config but does only relys on DNS host names? I have a quite long list of host names and a not that well maintained name server.

Hello, While testing recent snapshots (20131023 and 20131024) I encountered a problem with ProxyCommand. The regression tests all passed, but the use of ProxyCommand's in my ~/.ssh/config resulted in name resolution errors; even if CanonicalizeHostname was explicitly set to "no." The patch included inline below fixed the issue: Index: ssh.c

Hello, On macOS, Terminal?s ?New Remote Connection?? command runs ssh in a new window like this: login -pfq $USER /usr/bin/ssh $HOST Here, login executes /usr/bin/ssh with argv[0] set to ?-ssh?. If $HOST has a ProxyJump configuration, the resulting ProxyCommand is: -ssh -W '[%h]:%p' $JUMP_HOST Because of the leading hyphen, this fails to execute. If the user?s shell is zsh, the

Hello! I'm hoping that Gmail won't HTML format this mail so that I'll get flamed :) Anyway, my question relates to ssh_config. The problem I find is that the Host pattern is only applied to the argument given on the command line, as outlined in the man page: "The host is the hostname argument given on the command line (i.e. the name is not converted to a canonicalized host name

Hey folks, As most of everyone, I use OpenSSH for almost everything and whenever I can: backups, sync, Git, configuration management, and of course console sessions. So much for an intro ;) My laptop and I roam between three networks, though sometimes I leave the laptop at the office overnight, or hop over to the third site for an hour or two. I'd like to find a way to configure OpenSSH (or

Dear openssh developers and users, I'm new to the list, and my apologies if this question has been asked before. I've tried to look for answers and haven't succeeded, which is why I'm asking. Here's the situation: I'm connect to a dual-stacked host with A and AAAA records. The IPv6 connectivity to the host is broken. When connecting to the host directly from my client

Hi, OpenSSH 9.4 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This is a bugfix release. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is also available via git using the instructions at

Ok, so my situation : Connecting to internal machines via a bastion server in AWS. Because I'm raising and tearing down the infrastructure a lot at this stage with Terraform, the IP addresses change. For the management subnet, I have a private DNS zone defined, and a public zone with a record for the bastion server. What I wanted ; to just be able to define a config entry thus : ---

My company uses a certain product which forces me to use a jumphost / ssh proxy. When connecting to a server I have to type "ssh myuser at technicaluser@targethost at jumphost" everytime. I tried to simplify this by editing my ssh_config and putting this into the file: Host targethost ProxyJump technicaluser at jumphost These lines are recognized but don't work like intended

Hello everyone, my workplace has gotten the idea of centrally maintaining a file in ssh_config syntax so that employees do not need to discover every new machine and configure it on their own. Since it's a case of "let's get started now, and properly think it through later", right now, a typical entry might look like > Host [product]-[Customer] > Hostname

OpenSSH 9.6 has just been released. It will be available from the mirrors listed at https://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested

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
