Ahh, in my scanning through the `ssh_config` manpage, I missed this, and change logs seem to indicate this feature has been around since at least 2017, so should not cause

Nope? just tried it, at this time it's relative to whatever directory you call `ssh` from. Which if

Hi all, I noticed a bit of an odd issue with maintaining `known_hosts` when the target machine is behind a bastion using `ProxyJump` or `ProxyCommand` with host key clashes. Client for me right now is OpenSSH_9.3p1 on Gentoo Linux/AMD64. I'm a member of a team, and most of us use Ubuntu (yes, I'm a rebel). Another team who actually maintain this fleet often access the same machines

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, I'm very grateful for the new ProxyJump option. It helps tremendously! One small question I'd like to ask, though: Is there a way to skip one (mostly the first) jump host if the machine is in some specific network? For example, from home, I (resp. a shell script) need to jump to the office's server, a customers' login host, and then to the destination node; from the

Hello, it seems I cannot use: $ ssh -J root at 2a01:4f8:1c1e:528d::1 root at west-coast Invalid -J argument (The west-coast is stored on the jump host in between in /etc/hosts.) $ ssh -J root at 167.235.141.44 root at west-coast Works as expected. Also $ ssh root at 2a01:4f8:1c1e:528d::1 does work as expected. I do have native IPv6. This is on Debian 12 Bookworm: $ ssh -V OpenSSH_9.2p1

Hi, I'm using ProxyJump via a local sshd (in a separate network namespace) to connect to a remote host. It works fine the first time, but if I connect several times in a row in a short period of time, I suddenly get a "Connection reset by peer" error. This happens to be reproducible. If I wait a few seconds (let's say 15 seconds), the connection is restored. I have tried to
