| USR9106 hi,
my usr9106 (Software Version: 0844_042105-2.14L.01A.A2A015i.d15h) does not properly use its secondary dns server. this error occurs when the primary dns server of my internet provider is partially out of order, i.e. certain domains are not resolvable by the primary dns server but only by the secondary.
the LAN IP Address of my usr9106 is 192.168.1.1. this ip adress is in the /etc/resolv.conf as the nameserver. if i add the primary dns server manually in /etc/resolv.conf i stay with this problem:
debian:/home/xxx# nslookup www.ubuntu.com
;; connection timed out; no servers could be reached
debian:/home/xxx# ping www.ubuntu.com
ping: unknown host www.ubuntu.com
only if i add the secondary dns server to the /etc/resolv.conf it works. for example
xxx@debian:~$ nslookup www.bmw.de
Server: 195.78.6.36 primary dns server
Address: 195.78.6.36#53
Non-authoritative answer:
Name: www.bmw.de
Address: 192.109.190.4
xxx@debian:~$ nslookup www.ubuntu.com
Server: 195.78.6.210 secondary dns server because primary fails
Address: 195.78.6.210#53
Non-authoritative answer:
Name: www.ubuntu.com
Address: 82.211.81.166
i don't want to put the dns servers into the /etc/resolv.conf's of all my computers but expect my usr9106 to use the secondary dns server if the primary fails. but it isn't working like that. why?
thanks in advance for any help or explanation. |
