I have a situation where I want to set up a local network (via PPP on
direct serial lines) to access my internet link (PPP on a 28.8 KB
modem line).
I've read the NET-2 docs and the PPP docs. It seems like proxy arp is
what I need to set up, but it's not clear how. I'm not running an
ethernet, my network devices are all ppp devices.
Looking at the proxy arp code in pppd-2.1.2d, it seems that pppd does
not set up a proxy arp entry for anything but ethernet. Is this true?
[...]
/*
* Check that the interface is up, and not point-to-point
* or loopback.
*/
if (ioctl(s, SIOCGIFFLAGS, &ifreq) < 0)
continue;
if ((ifreq.ifr_flags &
(IFF_UP|IFF_BROADCAST|IFF_POINTOPOINT|IFF_LOOPBACK|IFF_NOARP))
!= (IFF_UP|IFF_BROADCAST))
continue;
The arp program in net-tools-1.2.0 seems to support many different
hardware types, including "slip" and "ppp" along with "ether".
Has anyone set up a local network like this?
Can anyone give me any hints?
