I am using 'Tiger', use the terminal, icon found in 'Applications/Utilities'.

'ifconfig en0' will get you the ethernet interface details
'netstat -r' will get you routing
'scutil --dns' will show the dns resolvers configured

i'm keen to solve this problem, regardless of whether I reinstall..

my skills at network admin on a Mac are pretty limited too, so not sure
how to check on IP and DNS stuff. If I look under TCP/IP settings under
system preferences>network it is just select to 'Using DHCP' and doesn't
show any DNS settings.

yep, i can successfully ftp to ftp.nz.debian.org as anonymous. How would I
determine whether there is a proxying setting for gnome/kde that needs
changing?

just tried using apt-get and this hangs too..

That's really interesting.  I think that there's something really odd
happening here.  I am not so sure that a reinstall will fix this.  It's
possible that there's some other subsystem getting in the way, but I'm
bothered if I can think of what it might be.

The address 10.1.1.1 seems to be a valid DNS server so I can't
understand why it's not working for you.  I really recommend having a
look at what your Mac thinks it's doing (IP and DNS wise) and go from
there.

Do you want to proceed debugging this or are you going to just
reinstall?  If you can ping www.google.co.nz that makes me think that it
should be working now.  Can you use a non web browser, like FTP to try
out that?  If you can FTP to ftp.nz.debian.org as anonymous then the
problem isn't so much in your DNS / IP setup and with your browser(s).
Is it possible that there is a gnome / KDE environment setting on your
box to do with proxying?

Cheers,
Michael.

yep, the DNS Server is now set back to 10.1.1.1 despite me having
previously set it to 192.168.1.1

i can ping 10.1.1.1 and www.google.co.nz successfully.

nslookup www.google.co.nz 10.1.1.1 gives:

Server:  10.1.1.1
Address: 10.1.1.1#53

The IP address 192.168.1.102 is completely acceptable since it is part
of
the
network range of the LAN you appear to be in.


and route gives:

This is OK too.  It just says that you have one network on ethernet 0
and
it
is the default path for all network traffic.


cat /etc/resolv.conf:
nameserver 10.1.1.1

Back to this again?  Had you manually changed this to 192.168.1.1?  If
so,
then when you went "ifup eth0" I suspect that the DHCP server issued
you
with this nameserver and dhcpcd overwrote your old /etc/resolv.conf

Can you ping 10.1.1.1?


traceroute:
bash: traceroute: command not found

Gah!  You need the package "traceroute" (can you believe it).

Try this and post the results:

nslookup www.google.co.nz 10.1.1.1

If nslookup isn't installed then try this:

dig @10.1.1.1 www.google.co.nz

Basically, either one of those commands will tell you whether 10.1.1.1
is
really a nameserver that you can reach.  If you don't get an IP for
www.google.co.nz, then try the same commands but with 192.168.1.1

If 192.168.1.1 is able to resolve www.google.co.nz then you need to
console to your Linksys and try to work out why it is issuing the DNS
server 10.1.1.1 instead of
192.168.1.1

Please post the outputs anyway.

I wonder whether you have two DHCP servers on the LAN since I think
you
mentioned connecting a Linksys to another ADSL router.  I might be
mistaken,
but that could lead to some real confusion.  Anyway, if one host is
working
reliably and the other is not then it's harder to blame the network
itself
(but not an impossible scenario given the variability of OSs.

Good luck!
Michael.

I stand by the config I posted earlier.

Also, the manner of the problem you have reported could still be

explained

by misconfiguration in Firefox.  Is is possible that Firefox is

attempting

to contact a Proxy server?

If you follow the instructions in my previous email then we can at

least

eliminate or prove some simple network problems.

Michael.

Weirdly there is no 127. route, but otherwise looks fine.

Can't remember ever seeing 127.0.0.1 in a "route -n".  Maybe

you're

thinking of "route -nC" Nick.

Anyway, the absence of 127.0.0.0 is not important here.


cat /etc/resolve.conf gives:

clearly wrong, your dns server won't be 10.1.1.1.

Not *clearly* wrong since the Linksys maybe issuing another one of

its

private IP interfaces as the DNS server address.  But yes,

192.168.1.1

is

likely to be a better bet. The PC can get to it because it's only

got

one

default route - via 192.168.1.1 as it happens!


Try changing this to 192.168.1.1 (if the router provides dns

services)

or
the ip address of your isp's dns server if it doesn't.

If that doesn't work, try changing /etc/network/interfaces as

such:

--- Snip here
auto lo eth0
iface lo inet loopback

iface eth0 inet dhcp

mapping hotplug
        script grep
        map eth0

iface dsl-provider inet ppp
        provider dsl-provider

iface ppp0 inet ppp
        provider ppp0
--- Cut here

Then do "ifdown eth0" and then "ifup eth0".

Then do:

host www.google.co.nz
arp -a
ifconfig eth0
route

By the way, do you have a link light on your network card and on

your

Linksys?

Michael.
