Re: [opensuse] No network of leap 42.3

I fired up wireshark. Wireshark is able to capture all of the network
chatter occurring on my lan from the other devices. There is a
repeating dhcp discover associated with ip 0.0.0.0 which I assume to
be the 42.3 machine. Still no address assigned to the 42.3 machine.

Here is the ifconfig-eth0 file. The only thing I find odd is the name
given in the file. Not sure what the (2) is in there for, it would
suggest there is a 1 somewhere but I have never found it. This system
was literally a straight install with no glitches, a couple of
updates, and then a network failure. I did not even look at the
network until I no longer had it. Has me stumped.

I have read all of your comments and here are a couple of things that
I did not mention in my first post. Both the default gateway and
nameserver are set to the router ip address. I am not even able to
ping the router or any other device on the lan. With a static ip
address ifconfig shows eth0 with the correct ip address. Using dhcp
ifconfig shows eht0 with no ip address. While using dhcp it always
times out and I get the message 'setup in progress'. I believe there
was a kernel update in the last batch of updates. Could the e1000e
module be broken. The computer acts like everything is okay with the
network and is just waiting for a response from the router. The
router on the other hand never receives any data from the computer. I
will get the ifconif-eth0 file posted as soon as I can get it over to
this computer. I have looked it over and see nothing different from
the same file on the machine I am using now.

I assign ip's to expected instruments, phone, tablet, laptops, and allow
the router to assign addresses to "other" machines. wifi is just another
connection different than wire.

While a good DHCP + DNS set-up can handle the dhcp telling the dns about
devices, having static, predefined addresses for key devices like the
printer,
the router/gateway can simplify a lot of things about configuration and
debugging.

It can also simplify ACLs.
Personally I hate the idea of early binding ACLs but sometimes it is very
useful.

I can tell my printer to refuse any device on the network that isn't my PC,
my
phone or or my laptop or my tablet. It is a simple security hack.

I'm sure Patrick can give other illustrations.
