Subject DO NOT REPLY [Bug 49154] New: sshexec doesn't use hostkey from known_hosts on different ports for the same host

           Summary: sshexec doesn't use hostkey from known_hosts on
                    different ports for the same host
           Product: Ant
           Version: 1.7.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Other
        AssignedTo: notifications@ant.apache.org
        ReportedBy: kelfe@gmx.de


If you have a known_hosts file with
1.2.3.5 ssh-rsa keyA
then ant sshexec and openssh can use that to connect to 1.2.3.4 on port 22

ssh can use that line to connect to an sshd on 1.2.3.4:2222 as well (without
reconfirming the host key)

ant sshexec rejects the host key on port 2222 in that case

if you have a different host(key) (via firewall/redirect) on port 2222 the ssh
commands allows you to add that different host key in the form
[1.2.3.4]:2222 ssh-rsa keyB

to make ant sshexec work to the same host on different ports you need to add
the second line by hand
1.2.3.4 ssh-rsa keyA
[1.2.3.4]:2222 ssh-rsa keyA

expected would be that sshexec accepts the first host key line already like
openssh does
