View file @ b612eddf
Mon Mar 2 20:45:29 1998 Philip Blundell <Philip.Blundell@pobox.com>
* interface.c: New file, contains code shared between ifconfig and
netstat.
* sockets.c: Likewise.
* ifconfig.c (ife_print): Add support for latest /proc/net/dev
format.
* ifconfig.c (ipx_getaddr): Reformat.
* lib/inet6_gr.c: Don't #include <netinet/ip6.h>
Fri Feb 27 20:43:34 1998 Philip Blundell <philb@gnu.org>
* ifconfig.c (if_print): When displaying all interfaces, get list
from /proc/net/dev rather than using obsolete SIOCGIFCONF.
(main): Protect portsel code with #ifdef.
* lib/ash.c: Tidy up.
(pr_ash): Print the address in canonical Ash notation, and accept
FF termination.
Fri Feb 13 18:47:09 1998 Philip Blundell <philb@gnu.org>
* ifconfig.c (ife_print): Only print the broadcast addreess if the
