             Bug #: 2020
           Summary: Remote-to-remote copying doesn't work when second host
                    not on port 22
    Classification: Unclassified
           Product: Portable OpenSSH
           Version: 6.0p1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: scp
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: daniel.kullmann at gmx.de


It is not possible to specify a different port for the second remote
host in a scp command line, e.g.

scp -P 3434 host1:file -P 8765 host2:file

is not possible, because the second -P is in an illegal position.

This would not be bad if the port could be specified in another way,
but scp does not use the Port setting in .ssh/config for the second
host. It does use the setting for the first host, though.

Actually it *is* looked up in ~/.ssh/config, but on the remote host.

By default, scp remote1:foo remote2:bar actually runs "ssh remote1 scp
foo remote2:bar" (this is behaviour inherited from rcp).

You need to either put the port number in the config file on the remote
host, or use scp's "-3" option to do a 3-way copy which will use
the
local config file.
