Bug ID: 3015
Summary: ssh: usability issue with -J and multiple jump hosts
Product: Portable OpenSSH
Version: 7.9p1
Hardware: All
URL: https://bugs.debian.org/929669
OS: Linux
Status: NEW
Severity: minor
Priority: P5
Component: ssh
Assignee: [email protected]
Reporter: [email protected]
When I try to proxy jump through multiple hosts using the most
intuitive way to do that (multiple -J options), ssh misleads me into
believing that ssh only supports a single jump host but if I use the
right syntax by separating the hosts with commas then it works fine.
I suggest that ssh either automatically combine the values of all the
proxy jump options using commas or print an error directing the user to
manually combine the values of all the proxy jump options using commas.
$ ssh -J master.debian.org -J paradis.debian.org draghi.debian.org
echo yay
Only a single -J option permitted
$ ssh -J master.debian.org,paradis.debian.org draghi.debian.org echo
yay
yay
