next in thread | raw e-mail | index | archive | help
Anyone up for adding text to the scopeid field in the ifconfig(8)
output for IPv6 addresses? Other OSes do. To avoid too much
disruption to the current format, the text is appended after the
currently printed hexadecimal field.
Example:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet6 fe80::290:27ff:fe13:2540%fxp0 prefixlen 64 scopeid 0x5(site-local)
While we're at it, update the in6.h file to include all scopes
in RFC4291.
Look OK? Anyone up for applying these?
