hi all ,
i have a script , but i need a script man to have a look on and tell me why the dns is not working on this script.

the user can get ipv6 ip , but it cant get ipv6 dns ???!!

here is the script :

root@debian:~# cat /etc/ppp/ipv6-up.d/setupradvd
#!/bin/bash
ADDR=$(grep ^$PEERNAME: /etc/ppp/ipv6-addr |cut -f 2 -d
if test x$ADDR == x ; then
echo "No IPv6 address found for user $PEERNAME"
exit 0
fi

#configure locally
#ifconfig $IFNAME add 2001:db8:1:$ADDR::1/64
ifconfig $IFNAME add 2001:4428:200:8154:aaaa:$ADDR::1/80
#2001:4428:200:8154:aaaa::/80
#generate radvd config
RAP=/etc/ppp/ipv6-radvd/$IFNAME
RA=$RAP.conf
echo interface $IFNAME >$RA
echo '{ AdvSendAdvert on; MinRtrAdvInterval 5; MaxRtrAdvInterval 100;' >>$RA
echo ' prefix' 2001:4428:200:8154:aaaa:$ADDR::/80 '{};' >>$RA
echo ' RDNSS 2001:db8::1 {}; };' >>$RA

#start radvd
/usr/sbin/radvd -C $RA -p $RAP.pid

Showing us the script is a good start (and would be a lot easier to read if you posted it in CODE tags which are most easily accessible in Advanced mode via the # button).

Showing us how you used the script and the output and telling us how the output differs from your expectations would be a good next step.

The script has uninitialised variables unless they are environment variables: IFNAME and PEERNAME. If you show us how you ran the script, please also show their values.

Have you tried running the script with tracing on or simulating its actions line by line at the command prompt?
