ping6

[eric@certus.bz]

Hi,
I've found what I think is a bug in the ping6 tool. Without the -n option,
it puts the hostname inside the parenthesis instead of the resolved ip
address as demonstrated below:

ericat@hydra:~/iputils-s20101006$ ping6 ipv6.he.net
PING ipv6.he.net(ipv6.he.net) 56 data bytes
64 bytes from ipv6.he.net: icmp_seq=1 ttl=58 time=186 ms

I expect output like this:

ericat@hydra:~/iputils-s20101006$ sudo ./ping6 ipv6.he.net
Password:
PING ipv6.he.net(2001:470:0:64::2) 56 data bytes
64 bytes from ipv6.he.net: icmp_seq=1 ttl=58 time=187 ms

Here's a very simple patch to ping6.c for proper behaviour:

ericat@hydra:~/iputils-s20101006$ diff ping6.c.orig ping6.c
979c979
<       printf("PING %s(%s) ", hostname, pr_addr(&whereto.sin6_addr));
---
>       printf("PING %s(%s) ", hostname, pr_addr_n(&whereto.sin6_addr));

Cheers,
