Description Michael Tatarinov 2013-11-13 19:04:40 AEDT

Hello

For use link-local IPv6 address need to specify the interface. It's possible in command line but impossible in configure file.

$ ssh fe80::203:47ff:fe98:7799%em1
it's ok, but
$ ssh -F .ssh/config_test test
percent_expand: unknown key %e
$ cat .ssh/config_test
host test
 HostName fe80::203:47ff:fe98:7799%em1

You can include a literal '%' using '%%', so:

host test
 HostName fe80::203:47ff:fe98:7799%%em1

Does that solve your problem?

Yes, it's solve problem. Thanks!
Then it should be documented.

Done. The manual text (coming in openssh-5.7) now reads:

>     HostName
>             Specifies the real host name to log into.  This can be used to
>             specify nicknames or abbreviations for hosts.  If the hostname
>             contains the character sequence `%h', then this will be replaced
>             with the host name specified on the command line (this is useful
>             for manipulating unqualified names).  The character sequence `%%'
>             will be replaced by a single `%' character, which may be used
>             when specifying IPv6 link-local addresses.

>             addresses are also permitted (both on the command line and in
