It also works from putty if you put the me@..... in the hostname field I have put a primitive hack to get around the issue.

    if ( ( $target =~ tr/\@// ) < 2 )  {
    ($user, $passwd, $ipv6, $host, $port) =
        $target =~ m{^
                       \s*               # space
                       (?:
                         ([^:]+)         # username
                         (?::(.*))?      # : password
                         \@              # @
                       )?
                       (?:               # host
                          (              #   IPv6...
                            \[$IPv6_re(?:\%[^\[\]]*)\] #     [IPv6]
                            |            #     or
                            $IPv6_re     #     IPv6
                          )
                          |              #   or
                          ([^\[\]\@:]+)  #   hostname / ipv4
                       )
                       (?::([^\@:]+))?   # port
                       \s*               # space
                     $}ix
                or croak "bad host/target '$target' specification";
    } else {

        $host = $target;
