I am using Redhat6.2 box. I rewrote one perl utility which uses iptables to calculate the traffic by each ip on the linux machine. I used this command
/sbin/iptables -L -n -v -x
In the program i use some calculations for getting the traffic for current day which is logged into the database table as the total no of bytes for the current month. Eveything was working perfectly until the iptables gave one problem. The no of bytes was reset and started over again. Does any body know when the reset (i.e the upper limit of the traffic no of bytes) will occur.
What exactly i need is the number of bytes used per month which is a number. The MRTG software gives graphs,stats and not a pure number. How can i get the no of bytes from MRTG?
Well I don't think iptables is the one that resets the number of bytes. The information is probably retreived from /proc/net/dev. I don't know what the largest value is, you would probably have to browse through the kernel code to find out what sets and resets this value.
I think it's an unsigned long (4 bytes) which would allow it to go up to 4GB's.
