Question

The Linux file /proc/net/dev reads like this:

Inter-|   Receive                                                |  Transmit
 face |         


        

Answer 1

According to http://www.onlamp.com/pub/a/linux/2000/11/16/LinuxAdmin.html, the meanings of each of the columns are:

bytes The total number of bytes of data transmitted or received by the interface.

packets The total number of packets of data transmitted or received by the interface.

errs The total number of transmit or receive errors detected by the device driver.

drop The total number of packets dropped by the device driver.

fifo The number of FIFO buffer errors.

frame The number of packet framing errors.

colls The number of collisions detected on the interface.

compressed The number of compressed packets transmitted or received by the device driver. (This appears to be unused in the 2.2.15 kernel.)

carrier The number of carrier losses detected by the device driver.

multicast The number of multicast frames transmitted or received by the device driver.
