Second NIC not working

[yoram]

Hi,
I have yet another issue
I installed a new 1GB NIC, its recognized by the system on "lspci"
but if moving the cable to this NIC it does not show on the net.
It's also not on the router's connected list, so, probably not initiated the DHCP process
for getting the IP address

Hi and thanks for your help
The pc used is an old Athlon 2500 based computer. Chipset is by Nvidia (eth0)
The new NIC is Realtec on the PCI bus and NOT connected to the network (eth1)
Following is the printout of the requested commands separated by ---------------

Hi Yoram and thanks for posting those results.

OK, two things to try:

Type the following

Code: Select all

sudo rm /etc/udev/rules.d/70-persistent-net.rules

Then shut your server down, swap the network cable from your old NIC to your new one and power your server back up again.

If that doesn't work then try the following:

Code: Select all

sudo vim /etc/networking/interfaces

Then press the [Insert] key once and add the following lines:

Code: Select all

iface eth1 inet dhcp
auto eth1

You need to add them after the section for the eth0 card. So, the file should now read:

Code: Select all

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

#Added by Yoram
iface eth1 inet dhcp
auto eth1

Escape out of edit mode and then type

Code: Select all

:wq

Then shut your server down, swap the network cable from your old NIC to your new one and power your server back up again.

Let us know how you get on

[yoram]

Like magic . . .. the first one worked perfectly
Could you pls explain what you saw in my reply
and what was the command you proposed that fixed that?


Thanks so much

Yoram

[The_Matrix]

You're asking me to give all my secrets away?? Never

Just kidding. the "[ 19.145275] udev[402]: renamed network interface eth1 to eth1-eth0" told me that Ubuntu was struggling to work out what NIC to activate. The "/etc/udev/rules.d/70-persistent-net.rules" file had the old card in it so by deleting it and rebooting Ubuntu added your new card to that file instead.

If at some point you swap them back then you'll need to delete that file again.

Anyway, glad it's all working now

[yoram]

Nice call on the device confusion
Do you think there is a way to help ubuntu decide which nic to use?
It seems that I'm going to switch between the two since the new one in not running 1G
but only 100M. could be a cable issue. still working on that

Yoram

[The_Matrix]

Try following the Plan B above. ie. adding the "iface eth1 inet dhcp....." to the interfaces file.

[yoram]

Plan b works like charm
before applying reconnection of the eth cable did not initiate the communication
after applying the fix it auto start the interface without restarting the computer

[The_Matrix]

Glad it worked for you Yoram. Thanks for feeding back
