Two NICs
Hello,
I'm trying to get a Fujitsu Siemens thin client working with 2 NIC's.
eth0 is on-board, eth1 is a pci board plugged in.
Both ethernet connections are recognized when loading the distribution, I've tried ascii & jessy.
Randomly after the install & configuration is completed one or the other NIC's becomes unavailable.
If I remove the pci board (I've tried different makes) every thing works fine.
Any good ideas please?
David.

May be a problem of names of the interfaces. I would try net.ifnames=0 on the kernel parameters.

Re: Two NICs
What is listed in dmesg when the NIC becomes unavailable?

Re: Two NICs
Thank you for the replies.
I have been trying various versions of Devuan, all seem to have the same issue.
I have added the MAC address to /etc/networks/interfaces and that seems to help, but it's not a complete solution, I think I need to add routing information.
I will see where to add the line net.ifnames=0 today.
I am struggling with looking at dmesg as when the interface becomes unavailable I can't SSH into the unit.
This unit, along with all the thin clients I use, is running headless.

Re: Two NICs
Can you offer me further help please? what do I do with net.ifnames=0
I've tried running it as a command and get told it's not a valid command, do I have to insert it into a file? if so which one?
I can see dmesg on the screen, but I can't export it, the only thing in it that refers to eth1 is a IPV6 error.

Re: Two NICs
You could add the line to the file
/etc/sysctl.conf
echo net.ifnames=0 >> /etc/sysctl.conf...will add the line to the end of the file.
You may need to reboot to activate the command.

that and or put net.ifnames=0 in /etc/default/grub, find the line as per below and enter net.ifnames=0 between the quotes.
GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0"then do,sudo update-grub and reboot machine
