Ironfighter Posted October 30, 2006 Report Share Posted October 30, 2006 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 : Home Page BootCode Version: BC_CX82xxx_4.1.0.28 Firmware Version: CX82xxx_4.1.0.38 Customer Software Version: NB1300_6_1038_1SD WAN IP Address Subnet Mask MAC Address 203.214.53.86 255.255.255.0 00:09:F3:08:4F:7B Home Page BootCode Version: BC_CX82xxx_4.1.0.28 Firmware Version: CX82xxx_4.1.0.38 Customer Software Version: NB1300_6_1038_1SD WAN IP Address Subnet Mask MAC Address 203.214.53.86 255.255.255.0 00:09:F3:08:4F:7B LAN IP Address Subnet Mask MAC Address 192.168.1.1 255.255.255.0 00:09:F3:08:4F:7A 192.168.1.1 255.255.255.0 00:09:F3:08:4F:7A Total Number of Lan Interfaces: 1Total Number of Lan Interfaces: 1 Number of ethernet devices connected to the DHCP server: 2 IP Address MAC Address 1 192.168.1.10 00:40:CA:C0:CD:16 2 192.168.1.5 00:01:02:00:28:A9 Ethernet Link Status: UP USB Link Status: DOWNNumber of ethernet devices connected to the DHCP server: 2 IP Address MAC Address 1 192.168.1.10 00:40:CA:C0:CD:16 2 192.168.1.5 00:01:02:00:28:A9 Ethernet Link Status: UP USB Link Status: DOWN 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.

ianw1974 Posted October 31, 2006 Report Share Posted October 31, 2006 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.

Ironfighter Posted October 31, 2006 Author Report Share Posted October 31, 2006 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 Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted October 31, 2006 Report Share Posted October 31, 2006 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. Quote Link to comment Share on other sites More sharing options...
Ironfighter Posted October 31, 2006 Author Report Share Posted October 31, 2006 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. Quote Link to comment Share on other sites More sharing options...
