I have just replaced my USB modem with a router/modem and things seem to
be working find on my Debian box behind the router, except for nslookup.
Is there something I need to amend to get it to work. Note I can still
access the e-World from my Debian box:

In Switzerland I would say "the dog is buried here" (how to
say in English?):

I entered your nameserver in my resolv.conf and it did not work.
For now try to use my configuration:
search foo.ch
nameserver 62.2.24.162
nameserver 62.2.17.60
nameserver 62.2.17.61


My Question:
Is it a problem if Michael uses my configuration?

Cheers

Sam

I can add that another machine (MacOS) on my LAN does nslookup okay,
indeed with the first mentioned nameserver. Furthermore, my
understanding is that I need a local nameserver for things to work so
I'm not sure putting a Swiss one for my UK is sensible. Indeed, it
isn't necessary since the MacOS machine can use the stated
nameservers... I'm guessing I've something else not set up such that
my Debian box, behind the router, isn't accessing the correct
nameserver...

The empty 'search' list looks wrong. Try removing the line altogether.

Yes, if I delete that line then it works fine. Upon rebooting I see
that /etc/resolv.conf which is a sym link to /etc/ppp/resolv.conf gets
updated:

michael@manchester-campaigns:~$ file /etc/resolv.conf;ls
-lt /etc/resolv.conf /etc/ppp/resolv.conf
/etc/resolv.conf: symbolic link to `ppp/resolv.conf'
-rw-r--r-- 1 root root 55 Aug 16 15:30 /etc/ppp/resolv.conf
lrwxrwxrwx 1 root root 15 Apr 4 09:26 /etc/resolv.conf ->
ppp/resolv.conf

which I think is something/where/how related to the old speedtouch
scripts I ran to use the Speedtouch USB modem.

I'll investigate. thanks, Michael

okay, it's nothing to do with speedtouch (sorry steve) since I've
update-rc.d remove speedtouch

but somehow /etc/ppp/resolv.conf is being created at boot time with
correct nameservers but an empty search string...

any ideas? something to do with /etc/ppp/ip*d/0000usepeerdns
but I've no idea how/when they are used and why?!?

Probably best to browse the various manpages and such, but another approach
is to just look around for clues to the settings, e.g.,

$ sudo find /etc/ppp -type f -exec grep -H search {} \;
/etc/ppp/ip-up.d/0dns-up:# 'search' or 'domain' directives or additional nameservers. Read the

That file (on my system) may have some leads to follow:

$ sudo less /etc/ppp/ip-up.d/0dns-up
...
# 0dns-up sets up /etc/resolv.conf for the provider being connected to. In
# conjunction with pppd's usepeerdns option it also handles dynamic dns.
# It expects to be passed the provider name in PPP_IPPARAM.

# Pppconfig creates a file in /etc/ppp/resolv for each provider for which the
# administrator chooses 'Static' or 'Dynamic' in the 'Configure Nameservers'
# screen. The files for providers for which 'Static' was chosen contain the
# nameservers given by the administrator. Those for which 'Dynamic' was chosen
# are empty. 0dns-up fills in the nameservers when pppd gets them from the
# provider when the connection comes up. You can edit these files, adding
# 'search' or 'domain' directives or additional nameservers. Read the
# resolv.conf manual first, though.
...

Anyway, maybe such an approach could turn up an empty 'search' entry in some
file on your system...

Good luck!

yeah i had a poke around, unsuccessfully. it must also get the actual
nameservers' IP nums from somewhere too...

Only one I can think of, do you have the resolvconf package installed?

some dsl routers "require" that the clients points to the router itself as the
dns server.
In other words:
Try to use the following /etc/resolv.conf in the client:
nameserver <router_ip_address>

Here marks the spot?

I use Demon, the second entry from Michael's resolv.conf is the wrong IP.
Should be 158.152.1.43 = cache-2.ns.demon.net and 158.152.1.58 = cache-1.

..42 is something else, not a public nameserver IAC. Just change .42 to .43
and it should be fine.

Are you using dhcp? How does your /etc/network/interfaces file look like?
The dhcp client also manipulates /etc/resolv.conf.

Yeah, using DHCP:
from /etc/network/interfaces:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian
installationauto eth0
iface eth0 inet dhcp

iface dsl-provider inet ppp
provider dsl-provider
# please do not modify the following line
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf


But I'm still unsure what I need to amend

I don't think so:
manchester-campaigns:/etc/network# dpkg -l |grep resolv
manchester-campaigns:/etc/network#

but I do have DHCP:
manchester-campaigns:/etc/network# dpkg -l |grep dhcp
ii dhcp-client 2.0pl5-19.3 DHCP
Client
manchester-campaigns:/etc/network#

Jamie - thanks for spotting that typo. I've changed it and although the
empty 'search' is still in /etc/resolv.conf everything does now work
fine (and note that both MacOS and XP had worked fine with .42 or .43!):

DEBIAN BOX:
michael@manchester-campaigns:~$ less /etc/resolv.conf
search
nameserver 158.152.1.58
nameserver 158.152.1.43
michael@manchester-campaigns:~$ nslookup www.bbc.co.uk
Server: 158.152.1.43
Address: 158.152.1.43#53

Non-authoritative answer:
www.bbc.co.uk canonical name = www.bbc.net.uk.
Name: www.bbc.net.uk
Address: 212.58.227.76


Ta, M

Description: nameserver information handler
Resolvconf is a framework for keeping track of the system's
information about currently available nameservers. It sets
itself up as the intermediary between programs that supply
nameserver information and programs that use nameserver
information. Examples of programs that supply nameserver
information are: ifupdown, DHCP clients, the PPP daemon and
local nameservers. Examples of programs that use this
information are: DNS caches, resolver libraries and the
programs that use them.

I use dhcp3-client which works with resolvconf, and also does dynamic
DNS. I don't know about the older (?) dhcp-client.

Neither of which would have solved your, wrong DNS address, though.

See the recommendations in the man-page of "dhclient-script" when using
the dhcp3-client package. But I have never done that.
