Tring to use netgraph system for some pruposes
(frame-relay/tunneling/sync) I found that it is too complicated to
follow naming schemes for different clients, and build firewall
tables And not very clean witch ngX for what.
There two patches:
first allow name netgraph network interface.
# ngctl msg ng0: setifname \"sync0\"
will name interace ng0 as sync0
second patch allows rename already named netgraph node (I don't understand why
netgraph designers don't allow this)
# ngctl name ng0: sync0
so small script will easy create interface:
mkif() {
name="$1"
ngname=`( echo "mkpeer iface dummy inet"; echo "msg .:dummy getifname" ) \
| ngctl -f - | perl -n -e '/Args:\s+\"(ng\d+)\"/ && print "$1\n";'`
if [ "$name" != "" ]; then
ngctl msg $ngname: setifname \"$name\"
ngctl name $ngname: $name
ngname=$name
fi
}
# SYNC interfaces
mkif sync0
# some other netgraph stuff
mkif sync1
...
mkif sync2
...
# framerelay
mkif frm0
...
mkif frm1
...
