How do I check the hardware

I have installed Debian on a new PC and cannot get the network to work. I suspect the network interface but don't know how to test it. It is a wired connection.

During the install, it failed to find the DHCP server so I set a fixed IP. I cannot ping out or ping in from another server.

ifconfig eth0 produces the following:

eth0 Link encaps:Ethernet HWaddr: 90:FB:A6:2F:9F:E5
inet addr: 192.168.1.102 Bcast: 192.168.1.255 mask: 255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metrics:1

RX bytes:0 (0.0 b) TX bytes:2520 (2.4 KiB)

"lshw" shows you the list of known devices.

show me:

Code:

ifconfig eth0
route -n
dmesg | grep eth

 

Thanks or responding Mark

The ifconfig etho returns the same values as above but with the RX dropped now at 3975479502

The route -n gives
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

dmesg | grep eth gives

eth0: RTL8101c at 0xf881a000, 90:fb:a6:2f:9f:e5, IRQ 185

 

Can you post your /etc/network/interfaces file?

 

Thanks Falko

I will do that in a couple of days as I am away on a business trip at the moment

 

The /etc/network/interfaces file contains

auto lo
iface lo inet loopback

iface eth0 inet static
address 192.168.1.102
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.1
dns-search patcomsys.com

 

Is 192.168.1.1 the correct gateway? Did you try to ping local and public IP addresses?

 

Yes, 192.168.1.1 is the address of my RV082 router. I can ping that from other windows boxes but I cannot ping the Linux box (192.168.1.102) from another Windows box

 

This really looks like a problem with your NIC. Do you have another one that you can use in this system?

 

Thanks Falko, I was afraid that might be the case, the NIC is on the motherboard. I will send it back to the suppliers
