Hi, I made my code as simple as possible. Just open devices, read from one of them and send it thru the other one and vice versa. May be the problem is about some kind of loop. But i couldn't figured it out. Any other ideas? On Mon, Jan 11, 2010 at 10:05 PM, Aaron Turner <synfinatic () gmail com> wrote:

I'm trying to capture packets from eth0 and send them thru eth1. I'm doing some logging operations before sending thru eth1. I developed a simple application, when i deployed the box to our network, everything is fine but after a while capture speed dramatically decreases and starts to miss packets. I'm checking memory and CPU usage but everything seems fine and total system memory is stable. I'm using an Intel board with 1.6 Ghz atom CPU and 1 GB of RAM. I think my hardware is enough for capturing 10Mbit network. I'm confused about the speed decrease after some time. What do u think, can it be the libpcap's internal problem, or my misuse.Based on the info you've provided, I'm going to guess your code is the problem. I don't see this problem with tcpbridge which does the same thing. -- Aaron Turner http://synfin.net/ http://tcpreplay.synfin.net/ - Pcap editing and replay tools for Unix & Windows Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. -- Benjamin Franklin "carpe diem quam minimum credula postero" - This is the tcpdump-workers list.
