Internet Browsing on Knoppix Live DVD

[Ironfighter]

I know this is a Mandrake forum but I have posted this topic on Knoppix.net with no response as yet so I thought I wonder if those nice (and extremely intelligent) people at Mandrivausers.org can help me with this? :D Here we go:

 

I have been trying out the live DVD on an XP centrino laptop which has on board ethernet (and a wireless connection to our work server). When I boot up the laptop into windows I can just plug the ethernet cable into it and browse the net through a Netcomm Ethernet Plus 4 Modem Router.

I am sending this post from another linux machine (Mandrake 10.1) using the same modem router.

My problem is I cannot browse the internet at all from the Knoppix live DVD.

When I access the modem from the Mandrake machine by entering 192.168.1.1 I get the following output :

From a terminal on the Knoppix live DVD

I can ping 192.168.1.1

0% packet loss

I cant ping 192.168.1.5 because its firewalled

I can ping knoppix.net

0% packet loss

 

If I run ifconfig on the laptop I get amongst other things :-

 

eth0 inet addr: 192.168.10 Bcast: 255.255.255.255 Mask: 255.255.255.0

UP BROADCAST RUNNING MULTICAST mtu:64 METRIC:1

 

lo inet addr:127.0.0.1 Mask 255.0.0.0

inet6 addr: :: 1/128 Scope Host

UP LOOPBACK RUNNING MTU: 16436 Metric 1

 

If I try running netcardconfig = DHCP broadcast from device eth0Operation failed. FAILED. Hit return to exit.

Then try to ping 192.168.1.1 (the modem router) I get

connect: Network is unreachable

 

Finally I can browse the internet from a live Knoppix 4.0.2 live CD form the laptop - likewise Mepis Live CD

 

I really would like to use the live Knoppix 5 live DVD on this laptop (because more is better Smile)

 

Can anyone help get me surfing from the live DVD please. Very Happy

Your best bet would be do this:

 

ifconfig eth0 192.168.1.2/24

 

that will set up the interface with a static ip address. Then make sure you have a default gateway:

 

route add default gw 192.168.1.1

 

and then make sure you have DNS entries in /etc/resolv.conf - perhaps your router normally provides DNS, or use one from your ISP.

Thanks ianw1974 - I appreciate your advice (and would have backed a large amount of money on getting a response from you:)

 

I have done the first two tasks but have two questions about the DNS entry in /etc/resolv.conf

a) would an entry like

nameserver 192.168.1.1

DNS 203.89.226.24

be appropriate and if so how do I get permissions to save the edited file as itself?

 

Also when I run pppoe I get

Interface eth0 has MTU of 64 -- should be 1500. You may have serious connection problems (I have:))

pppoe: Timeout waiting for PADO packets

[ianw1974]

Hmmm, any reason for using pppoe from the machine? You'd only normally use this if using a USB/Ethernet attached adsl modem. If the router is managing the internet connection, you shouldn't need to use pppoe.

 

Normally, just typing "su" will give you privileges to then edit /etc/resolv.conf. Entries would be:

 

nameserver 192.168.1.1
nameserver isp_dns_server

 

where isp_dns_server is the ip address of a isp dns server.

Answer to question one - not really :D I am using a 4 port modem router via ethernet

Ive tried typing su but that didnt work so I set a password as root <passwd> still no good

I'll keep trying - if I can get it going using Knoppix 4 CD this must be doable. I will let you know how I go. Thanks again.
