Title: DNS Help needed
Post by: boycey on February 25, 2005, 10:55:36 PM

Hi,

I have a 6.1 (Mitel)server connected through BT ADSL and cannot access certain websites. We have proved this to a DNS problem with BT's DNS servers but cannot find how to resolve it. Can someone help point in the right direction, Thx

have you reconfigured the server without entering a master dns server ip?  If it is like SME, it really doesn't need one.  you might also update the list of root name servers that tinydns uses to resolve.

Have you installed SquidGuard?

this will block certain web sites.

Just a thought...

Have you got firewall between u and bt or is sme firewall?

If firewall then is port 53 ok?

I have had problems with tinydns and really wished that e-smith would return to bind.

anyway, tail your messages log and thry to access some site to see if you get any error messages and post them here. will see if i can help further.

Hi Guys,
Thanks for the replies. The server has been set up with no master DNS setting and we have also reloaded from scratch so no additional products are installed. It is plugged directly in the the BT router so the Box is our firewall.
We have been trying to find out how the box gets its DNS, so we could manually change it without much success, we have follwed mant tutorials but I think the Mitel boxes use different locations for the files so we have trouble finding them.
There are 3 DNS servers for the site we cannot get these are all BT ones (ns0,ns1 and ns2) and only ns2 seems to resolve the name.

create the following dir structure
/etc/e-smith/templates-custom/etc/resolv.conf
copy the file
/etc/e-smith/templates/etc/resolv.conf/25nameserver to /etc/e-smith/templates-custom/etc/resolv.conf
open the file with vi
should look something like

nameserver { "$LocalIP" }

you can now do the following
do a nslookup on the ns0, ns1 and ns2 or you can use the dns name

add 3 more lines to the file

nameserver ns0
nameserver ns1
nameserver ns2

save the file

now expand tha template with

/sbin/e-smith/expand-template /etc/resolv/conf

do a service network restart or reboot the box
