Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration.
This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. To receive this Complete Guide absolutely free.
I'm using a cable modem and trying to connect through a USB-Ethernet adapter. I don't want to use the router because I don't need it with the desktop computer and thus it's a pointless consumer (about 4-5 watts). The adapter is actually only for an Android tablet (4.0.3) but I connected it to the PC (Squeeze) for testing. The adapter's enclosure says ' JP1082 No: 030818', PCB says JP1082-970. There's nothing printed on the chip. On the included CD (USB LAN- RD9700) are driver for Mac and Win + Win CE and the source code for Win CE and Android. The Windows Logo Verification Report says 'Shenzen Lian He An Xin Software Development Co,Ltd'.
The Win drivers say 'Corechip Semiconductor, Inc.' The Android source is named jp1081android.c and the headers say 'JiaPeng NET JP1081 USB2NET' and 'JiaPeng NET JP1081 one chip USB 1.1' written by jokeliujl in 2010 under GPL v2. The Win CE source says 'Davicom Inc.' I guess I could upload this somewhere. If anyone's interested.
Lsusb says 'Bus 003 Device 004: ID 0fe6:9700 Kontron (Industrial Computer Source / ICS Advent) DM9601 Fast Ethernet Adapter' I tried to compile the Android module but since it's from 2010 I guess I would also need an older kernel. Anyway when connected with my Android tablet through the router it connects with original module qf9700 and dhcpcdeth0 just fine. I mostly think this is a hardware problem.
On desktop PC (kernel 2.6.32) I patched the dm9601 like explained here: I also tried out qf9700 from here: Both work - but of course only with router. The adapter is directly connected to the PC - no hub. I'm using wicd with dhcpcd as I've read is recommended. Also only with the router the LED of the adapter is lid. Normal LAN to modem.
Code: $ netstat -nr Destination Gateway Genmask Flags Metric Ref Use 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth1Output in Android should be similar. So when I connect with the adapter directly to modem I don't get an IP and can't browse the web. Only when I interpose the router it works.
On PC should I disable eth0 for eth1 to connect? Do I need the router because the modem is not giving enough power (-LED)? Yes, connection directly to modem is how I always do it. Can't say I remember having to adjust the MAC address. I installed the modem under fista years ago.
The router came with the modem (from my cable provider) but was only activated for the tablet a year or so ago. It's a Motorola SBV5121E modem and a D-Link DIR-615 router before someone asks. The router manual says: 'For Cable users make sure Clone MAC address option is ticked during Wizard installation (or enter the registered MAC) and make sure the service has been enabled/connected and is operational.'
Can't remember. So you're saying I should spoof the MAC address of the adapter cloning the PC's?
So you're saying I should spoof the MAC address of the adapter cloning the PC's? You could try that, yes, though I wouldn't know how to go about it. You could check the router to see whether you did set it to clone the MAC address of your PCs network card though as if you didn't then it probably won't be that which is causing the problem.
If it is the MAC address and you can't find a way to change it for the USB network adaptor you may need to find out how to change the MAC address which is accepted by the modem form your cable provider. Code: $ ping -b -w 3 255.255.255.255 WARNING: pinging broadcast address PING 255.255.255.255 (255.255.255.255) 56(84) bytes of data. When I had worked for our local cable company as an internet technician we ran into similar situations where the LED was lit, activity was shown but the system was not given an IP. The 'Max 2' is the allotted number of CPE that can be connected to the device at the same time as you may have two IP's allotted on your account/ or based on surfboard standards you are allotted the LAN MAC and CPE MAC allowing only one IP. Surfboard modems have a built in DHCP server that only activates if the cable modem does not get SYNC with the cable company, try disconnecting the cable from the modem and reboot the modem and see if you get a 192.x.x.x from the cable modem; this will narrow down to a modem or provider issue. Don't know if this is any info to help but it is a step that we used to reestablish MAC provisioning to the modem.
Once this was complete we would disconnect the CPE from the modem hook the modem back to cable company reboot the modem and establish SYNC then connect the CPE and 99/100 get IP from provider. This all stemmed back to a provisioning issue with the cable company as the MAC is bind to the MAC of the MODEM LAN MAC. Thanks for your reply, newbeliever. Directly connected to the modem the adapter's LED was never lid; the 'Link' LED on the modem is also off. When I disconnect from cable net, there's no difference. When I then connect the ethernet cable to the desktop PC the 'Link' LED is on but all I can get is 169.254.x.x.
So this should simply be a modem issue. I also get IPv4LL with the adapter. The adapter's MAC is not known to the modem's DHCP. Is it possible to measure the voltage on the ethernet port (maybe through an opened up cable)? What could I expect? 0.85 Volt, 1 Volt, 2 Volt?
Or maybe someone could just say that this modem is not capable to supply the adapter.
