https://bugzilla.mindrot.org/show_bug.cgi?id=3367 --- Comment #3 from James Z.M. Gao <gaozm55 at gmail.com> --- thanks very much. @dtucker another minor issue of the KnownHosts matching of `ssh-keygen -F` is that 'host' and '[host]:22' are not equivalent. ssh-keyscan host > k.txt # output: host key-type ... ssh-keyscan -p 22 host # also output: host key-type ... ssh-keygen -f k.txt -F host # found hostkey as expected ssh-keygen -f k.txt -F '[host]:22' # found nothing, whereas we should also match the same key as previous command -- You are receiving this mail because: You are watching someone on the CC list of the bug.

[Bug 3367] ssh-keyscan with non-22 port does not hash correct host
https://bugzilla.mindrot.org/show_bug.cgi?id=3367 --- Comment #4 from Damien Miller <djm at mindrot.org> --- 'host' and '[host]:22' aren't supposed to be equivalent - nothing in OpenSSH should ever write '[host]:22'. We deliberately avoid appending the port if it's the default because to do so would multiply 2x the number of cases the search and hashing code needs to consider. It's too much work for no practical gain -- You are receiving this mail because: You are watching the assignee of the bug. You are watching someone on the CC list of the bug.

https://bugzilla.mindrot.org/show_bug.cgi?id=3367 --- Comment #5 from James Z.M. Gao <gaozm55 at gmail.com> --- yes, '[host]:22' should not be output to knownhosts. For matching a host, the `hostport` in ssh-keygen should also remove the default 22 port, that is '[host]:22' --> 'host'. Then the matching time remain the same, in the mean while the matching logic are consistent with generating. -- You are receiving this mail because: You are watching the assignee of the bug.
