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

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

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

Hi OpenSSH devs, I?m wondering if the following has any merit and can be done securely ... If you could match on principals in the sshd_config, then (for example) on a gateway machine, you could have something like /etc/ssh/authorized_keys/sshfwd: cert-authority,principals=?batcha-fwd,batchb-fwd? ... /etc/ssh/sshd_config containing: Match User sshfwd PubkeyAuthentication yes

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

AFAIK everything you described here could be done using the AuthorizedKeysCommand or AuthorizedPrincipalsCommand directives. These can emit authorized_keys options (inc. permitopen) as well as the allowed keys/principals.

Hello OpenSSH team, (New subscriber and very first message... by the way thanks for bringing ssh to the wolrd). I have a question, maybe not so simple. _The question in short : _ Context? :_ _ In a jump configuration HostA -> (HostB) -> HostC The classical way to connect is : usera at hosta $ *ssh -J userb at hostb userc at hostc* And to make it "locally

Hello all. I wrote this small patch that allows having multiple tags on a configuration block in the openssh client configuration. For instance, with this configuration: > Host test-host > Tag change-hostname change-port-and-user > Tag jump-to-mybox > > Match tagged change-hostname > Hostname new-hostname > > Match tagged change-port-and-user > Port 12345 >

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, 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
