http://bugzilla.suse.com/show_bug.cgi?id=1006221 Bug ID: 1006221 Summary: command to remove outdated hostkey from known_hosts file wrong Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.2 Hardware: Other OS: Other Status: NEW Severity: Minor Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: aspiers@suse.com QA Contact: qa-bugs@suse.de Found By: Development Blocker: --- When a host with a non-default port is in the ~/.ssh/known_hosts file then the suggested command to remove it does not work. For example, if known_hosts contains: [192.168.42.129]:2222 ssh-rsa .... then connecting with an outdated hostkey gives something like: Offending ECDSA key in /home/user/.ssh/known_hosts:440 You can use following command to remove all keys for this IP: ssh-keygen -R 192.168.42.129 -f /home/user/.ssh/known_hosts but that command doesn't do the right thing; it removes the entry for the hostkey on the default port 22, not on port 2222. The correct command to suggest would have been: ssh-keygen -R [192.168.42.129]:2222 -f /home/user/.ssh/known_hosts This is a resubmission of the upstream bug: https://bugzilla.mindrot.org/show_bug.cgi?id=2169 which was rightly resolved as INVALID because the bug actually comes from a SUSE-specific patch: https://build.opensuse.org/package/view_file/openSUSE:Leap:42.2/openssh/open... The original source can be viewed here: https://github.com/openssh/openssh-portable/blob/00df97ff68a49a756d4b977cd02... -- You are receiving this mail because: You are on the CC list for the bug.

It will inflate what? It would hardly be a huge inflation to the source code.

Mentioning the ssh-keygen(1) man page should be enough, imho.

Surely that's not as helpful as providing a command they can use directly via cut and paste? -- You are receiving this mail because: You are on the CC list for the bug.

I was afraid it would inflate the patch by adding reverse logic to ssh-keygen argument parsing. Fortunately it didn't turn out to be the case, so it will be fixed in the next MU.

Yes, yet it also makes one more thing to think of when ssh-keygen behaviour changes, thus making it prone to rotting. -- You are receiving this mail because: You are on the CC list for the bug.
