RE: Can someone tell me the function for getting MIB-2 object values from Debian Linux Kernel ?
Nate,
I dont know if you are looking for this information for the same purpose
that I am viz. how to get the TCP/IP/UDP/ICMP statistics being gathered in a
G4 PowerPC that is running Debian linux.
Here's what I know so far.
>From this link http://packages.debian.org/stable/net/net-tools.html, I
downloaded the source for the "netstat" application (the link for the source
code tar.gz file is in fineprint right near the bottom of the page.)
After looking at the code, files netstat.c and statistics.c , I found that
the statistics are stored (in a format described in statistics.c) in the
following files :
/proc/net/snmp
/proc/net/tcp
/proc/net/udp
/proc/net/ip
/proc/net/icmp
These files appear to be 0 bytes when you do "ls -al" but they actually
contain all the values for all of the following counters (the code is taken
from statistics.c).
( The netstat application reads these counters from the above mentioned
/proc/net files and displays them. I am still searching for those functions
which update these counters, and also how frequently are they updated - not
in real time, I guess ? )
struct entry Iptab[] =
{
{"Forwarding", N_("Forwarding is %s"), i_forward | I_STATIC},

Do let me know if this helps.
Happy Computing!

if you find such information out please post it to the list,
in my quests, MIB values seem to be a holy grail which almost
nobody knows the values. I've searched for hours on the net
to try to find hints, but could never find anything other
then TCP stats which is:
.1.3.6.1.2.1.6.9.0&.1.3.6.1.2.1.6.9.0
at least it works for me under debian 2.2 & 3.0 and
kernel 2.2.19
