Hi Jim,

re: Did you try leaving DEFROUTE=yes in the ifcfg-enp1s0 file and
change it to 'no' or comment it out in the ifcfg-eno1 file?

> Yes, I just changed the ifcfg-eno1 DEFROUTE=no and performed an ifdown eno1 
> and ifup eno1.

I thought that you probably had, but I had to ask anyway...

re: the problem is being caused by here being two gateways defined

> Yes, that is most certainly my problem

Yup, yup, yup...

re:
> For comparison, can you send me your two ifcfg-<iface> files so I can see how

Sure.  Here are the configurations for two of our NOAAPort ingest machines
and the same for LSU/SRCC:

NB: on uni14, there are two 1 Gbps Ethernet interfaces that are bonded
together to give a total of 2 Gbps capability.  'eth2' is the private
interface to which one of our Novra S300Ns is sending its output.

re: did you bounce the eno1 Ethernet interface after trying to either
comment out DEFROUTE or setting it to 'no'?

> Yes, I even at one point just restarted the entire computer just in case.

Again, I thought that you would have, but I had to ask.

Cheers,

Tom
