I have 2 interfaces, but i don't know what to do with
First, let's keep this discussion on the list, not private. So I've added the list back in with this reply.
Second, as I look at the interface data, the packet counts make it clear that both are being used ... about equally for incoming traffic, but heavily favoring eth0 for outgoing packets. A look at your routing table ("netstat -nr" is one way to view it) will probably explain the TX imbalance.
Without knowing more about your setup ... for example, why the two interfaces are on different Ip networks (do they connect to the same or to different physical networks?), what services the host is running, what mix of LAN and Internet services the host accesses and how (what the routing table looks like is most of the "how" part) ... it is hard to recommend anything.
Really, from the standpoint of Linux, the system seems to be working. If you want to disable an interface temporarily, you *probably* want to use the command
ifdown eth0
or
ifdown eth1But the question of *whether* you should be running one or two interfaces really is better posed to the sysadmin at your site ... it is not particularly a Linux question. If his or her answer poses any issues that seem specific to Linux, then that would be a good time to come back here.
For example, I think I saw another message from you, earlier today, asking about controlling how the host accesses squid. It was too vague for me to reply to, but now that I see you have interfaces on different networks, the system's routing table should control which interface handles squid traffic (assuming the squid server is local, on one or the other network).
