openssh bugs - Dec 2008 - [Bug 1544] New: ssh-keygen -l on known_hosts file does not display hostnames for lines with comments

https://bugzilla.mindrot.org/show_bug.cgi?id=1544

           Summary: ssh-keygen -l on known_hosts file does not display
                    hostnames  for lines with comments
           Product: Portable OpenSSH
           Version: 5.1p1
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ssh-keygen
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: ssh-bugzilla at finestructure.net


Created an attachment (id=1588)
 --> (http://bugzilla.mindrot.org/attachment.cgi?id=1588)
output of ssh-keygen -l on known_hosts file with comments

I am encountering a small bug when using ssh-keygen -l with
known_hosts files.  For lines that have comments, the hostname is not
diplayed in the ssh-keygen -l output.  Please see the attachment for a
demonstration of the effect.

As you can see in the last command in the attachment, the hostname is
not present in the display, although the comment is.

The monkeysphere [0] program uses the comment field in known_hosts
files,
so this may present a problem for users of that program.

Thanks for the help.

I'm pretty sure that key comments in known_hosts files have only worked
"by accident" before. That being said, we should try to preserve
them...

We are freezing for the OpenSSH 5.6 release. Retargetting these bugs to
the next release.

This is tricky, because ssh-keygen -l has to support both known_hosts
and authorized_keys and there are no cheap heuristics to discern
between them.

The last patch is wrong, bug #1323 discusses the complexity of this in
more detail.
