> Subject: [PATCH] kdump-lib.sh: support dump ssh via local ipv6 address
>
> When dumping to ssh via local ipv6 address, the ssh parameter
> in kdump.conf is supposed to have the form like
>
> ssh user@fe80::cc1:8bff:fe90:b95f%eth0 What do you observe on dump target by tcpdump? Do you see the incoming packet with ipv6 scope link address?
>
> where "%eth0" is an existing network interface supporting ipv6.
>
> However, the get_remote_host function in kdump-lib.sh currently
> doesn't remove the network interface in the ipv6 address,
> causing the ip command in kdump_install_net function to fail,
> leading to a "Bad kdump location" message.
>
> This patch supports dumping ssh via local ipv6 address by enabling
> get_remote_host function to remove network interface in ipv6 addresses
