My basic assumption is that when a process’ only limiting factors are disk and CPU, then total system “iowait” + CPU usage should equal at least 100% of one logical CPU. (In other cases this will not hold. E.g. when downloading a file using wget, the network is often the limiting factor).
In my iptables script I have been experimenting with writing as finely grained rules as possible. I limit which users are allowed to use which services, partly for security and partly as a learning exercise.
Assume that we have two disks, one master SATA and one master ATA. How will they show up in /dev?
In Linux, is there any difference between after-ip link down-condition and real link absence (e.g. the switch’s port burned down, or someone tripped over a wire).
By difference I mean some signs in the system that can be used to distinguish these two conditions.
E.g. will routing table be identical in these two cases? Will ethtool or something else show the same things? Is there some tool/utility which can distinguish these conditions?
