Hi,

I'm struggling with ping6. On an IPv6 autoconfigured Etch machine:

# ip -6 addr list dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qlen 100
inet6 2001:738:0:1:214:22ff:fe13:e171/64 scope global dynamic
valid_lft 2592000sec preferred_lft 604800sec
inet6 fe80::214:22ff:fe13:e171/64 scope link
valid_lft forever preferred_lft forever

# strace ping6 fe80::214:22ff:fe13:e171
socket(PF_INET6, SOCK_DGRAM, IPPROTO_IP) = 4
connect(4, {sa_family=AF_INET6, sin6_port=htons(1025), inet_pton(AF_INET6, "fe80::214:22ff:fe13:e171", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 2Cool = -1 EINVAL (Invalid argument)
connect: Invalid argument

I can't ping my own link-local address. Trying a neighbour:

# strace ping6 fe80::214:22ff:fe13:ed7a
socket(PF_INET6, SOCK_DGRAM, IPPROTO_IP) = 4
connect(4, {sa_family=AF_INET6, sin6_port=htons(1025), inet_pton(AF_INET6, "fe80::214:22ff:fe13:ed7a", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 2Cool = -1 EINVAL (Invalid argument)

Global addresses (either mine or the neighbour's) respond to ping6,
though.

What am I doing wrong?

Ahem, that works, thanks. It's even written clearly in the manual.
Too bad that I tried using the interface address instead of the
interface name:

# ping6 -I fe80::214:22ff:fe13:e171 fe80::214:22ff:fe13:ed7a
ping: bind icmp socket: Invalid argument

where strace reveals

socket(PF_INET6, SOCK_RAW, IPPROTO_ICMPV6) = 3
bind(3, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "fe80::214:22ff:fe13:e171", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 2Cool = -1 EINVAL (Invalid argument)

Am I using an overly old version of ping6?
# ping6 -V
ping6 utility, iputils-ss020927

As far as I can see, you should type the interface address directly
after the -I, so -Ieth0 and not -I eth0.

Well, no, -Ieth0 and -I eth0 both work. With interface address
instead of interface name it doesn't work either way.
