NAS-Identifier Patch

Hello,

At the moment hostapd sends only NAS-Ip in radius-packets. For a better
identification of a nas the radius-attribute nas-identifier would be
fine. I patched it into the latest CVS-version of hostapd (0.2.0). In
the atachment is the patch-file.

In each radius-packet the NAS-Identifier attibute will be included. You
can configure it in hostapd.conf.

eg. hostapd.conf:
NASIdentifier=foobar

Perhaps it is a new feature for the cvs.

regards
gunter
