Package: openssh-client Version: 1:7.9p1-10 Severity: normal File: /usr/bin/ssh 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 -- System Information: Debian Release: 10.0 APT prefers testing-debug APT policy: (900, 'testing-debug'), (900, 'testing'), (800, 'unstable-debug'), (800, 'unstable'), (790, 'buildd-unstable'), (700, 'experimental-debug'), (700, 'experimental'), (690, 'buildd-experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-5-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_FIRMWARE_WORKAROUND, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_AU.utf8, LC_CTYPE=en_AU.utf8 (charmap=UTF-8), LANGUAGE=en_AU.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages openssh-client depends on: ii adduser 3.118 ii dpkg 1.19.6 ii libc6 2.28-10 ii libedit2 3.1-20181209-1 ii libgssapi-krb5-2 1.17-2 ii libselinux1 2.8-1+b1 ii libssl1.1 1.1.1b-2 ii passwd 1:4.5-1.1 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages openssh-client recommends: ii xauth 1:1.0.10-1 Versions of packages openssh-client suggests: pn keychain <none> pn libpam-ssh <none> ii monkeysphere 0.43-3 ii ssh-askpass-gnome [ssh-askpass] 1:7.9p1-10 -- no debconf information -- bye, pabs https://wiki.debian.org/PaulWise
