How can I create an SSH protocol link from my browser which will use a jump host?

  • 772

Not sure whether this should be going at serverfault or stackoverflow but starting here.

I can create an SSH link to open in my terminal application (Secure CRT) that looks like this and it works fine:

<a href="ssh://192.168.1.1">Open SSH</a>

I now want to be able to create such links that will go via a jump host but I can't work out if that can be done from one of those URLs.

The sort of thing I was wondering about doing was along the lines of:

<a href="ssh://192.168.1.1?o=ProxyJump%3Djump.host">Open SSH through jump host</a>

ssh

    No, AFAIK you can't use any "esoteric" options in a SSH URI. As far as I know there have been draft URI specs for SSH:

    but that never became much of an actual supported standard.

    I think that only part of the conventional the URL spec that works with many SSH clients is to provide a username and host.

     ssh://[user@]host[:port]

    I could test that PuTTY supports the port-number in the URI.
    The common openssh client states in the release notes:

    • ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g. ssh://user@host or sftp://user@host/path. Additional connection parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not implemented since the ssh fingerprint format in the draft uses the deprecated MD5 hash with no way to specify the any other algorithm.
