I have a 10.3 virtual machine with 4 network interfaces. I need 4 nics because my nagios will be monitoring servers on 3 separate networks and the 4th nic is used to send out notifications.
My issue is that periodically one interface will go down. I restart the network and it comes up…but then another goes down. At times it worked fine until I reboot.
Should I be able to have 4 separate networks connected to my linux box?
any ideas?
Without answering your question directly because you lack info about your NICs and how they are configured,
If you aren’t able to troubleshoot your problem you can also architect your way to avoid your existing problem… For instance, instead of connecting directly to each network you could configure other machines to act as gateways to those networks, then simply configure a persistent ROUTE pointing to each of those Gateways as entryways to their specific networks.
If as you say you are deploying Nagios in a virtual machine then you also probably have many options configuring combinations of physical and virtual network adapters.
So, many ways to skin a cat…

You have a principle questionn: “Should I be able to have 4 separate networks connected to my linux box?”. The answer is: Yes.
It will be a bit more difficult to cure your prblem as 10.3 is out of support for some time. That not only mean that if there is some bug when you try to use 4 separate networks, there will be no patch for 10.3. It also means that most people here cannot easily try to recreate your problem on a 10.3 installation.
