/proc/net/dev_mcast
 

Hi friends,
I am doing multicast testing. I want to read the entries in the
/proc/net/dev_mcast means which entry is for what.Any one can explain
it in detail or any link where i can get the same. Thanks in advance.

You can get this information from the appropriate kernel source file (you just have to know how to read it). In this case, it goes as follows:

First is the index of the interface (padded with spaces on the right so the whole field takes up 4 columns). Second is the name of the interface (space-padded to 15 columns). Next is the number of dmi users (space-padded to 5 columns), followed by the number of dmi gusers (space-padded to 5 columns). Last is a byte-by-byte hexdump of the dmi address.
