Bug ID: 2935
Summary: improve documentation of "ssh-keygen -R" to mention
"[hostname]:port"
Product: Portable OpenSSH
Version: 7.9p1
Hardware: Other
OS: Linux
Status: NEW
Severity: enhancement
Priority: P5
Component: ssh-keygen
Assignee: [email protected]
Reporter: [email protected]
Improve the documentation of ssh-keygen's -R parameter to explicitly
describe how to delete the line in the "known_hosts"-file for
non-standard port connections.
current:
___
-R hostname
Removes all keys belonging to hostname from a known_hosts
file. This option is useful to delete hashed hosts (see the -H option
above).
___
proposed:
___
-R hostname
-R [hostname]:port
Removes all keys belonging to hostname and port from a
known_hosts file, brackets and ":port" may be ommited if the standard
port (22) is used. This option is useful to delete hashed hosts (see
the -H option above).
___
Personal remark, at least in the documentation the use of "[]" may lead
to misinterpretation, therefore the explicit notion of them in the
proposal. It would seem that the use of the representation as
"hostname:port" is more natural.
Kind regards,
Thomas Hofmann
