Description of problem: man 1 ssh describes: > -L [bind_address:]port:host:hostport > IPv6 addresses can be specified with an alternative syntax: > [bind_address/]port/host/hostport or by enclosing the address in > square brackets. Syntax with slashes - as described - does not work: mfaux@reykjavik ~ % ssh -L '1234/::1/1234' 1.2.3.4 Bad local forwarding specification '1234/::1/1234' Version-Release number of selected component (if applicable): openssh-clients-5.4p1-3.fc13.i686 How reproducible: Always Actual results: If executing "ssh -L 1234/::1/1234 server" ssh closes with "Bad local forwarding specification '1234/::1/1234'". Expected results: ssh should interpret the syntax as described in the man page. Additional info: Workaround: Use "enclosing address in square brackets" method: "ssh -L '1234:[::1]:1234'".
