I'm not sure if this helps Girish, but for the record, yes we use npppd. All
we've done so far is adding interface group support, using the filter-id to
assign groups, and dhinfo stuff. No limits yet.
We still use the pre-new-config version, which makes our patches rather old.
Also, I believe Yasuoka told me that pf tags would probably be preferred over
interface groups, so I guess our approach might not suit OpenBSD.
However, for the record, our implementation uses the concept of adding the
groups to the config
if ((val = npppd_config_str(_this, config_key_prefix(buf1, "ifgroup"))) !=
NULL) ...
and then assigning them to either tun or pppx interfaces
if (ioctl(sock, SIOCAIFGROUP, &ifgr) != 0) ...
for static configuration, and using the realm bits to associate filter-ids with
groups
if (radius_get_raw_attr(pkt, RADIUS_TYPE_FILTER_ID, &group, &len) == 0) {
...finding the realm...
_this->ppp->realm = realm0;
in case someone is interested ;)
