Select backend, we use ULOG2 as default, if you need PCAP u must change variable ENGINE in build.sh to PCAP
|
|
|
|
Compile it:
|
|
```bash
|
|
./build.sh
|
|
```
|
|
|
|
Start it:
|
|
```bash
|
|
./fastnetmon
|
|
```
|
|
Server configuration for PCAP:
|
|
no configuration needed
|
|
|
|
Server configuration for ULOG2:
|
|
```bash
|
|
iptables -A FORWARD -i br0 -j ULOG --ulog-nlgroup 1 --ulog-cprange 32 --ulog-qthreshold 45
|
|
```
|
|
|
|
If you use PCAP, u can set monitored interface as command line parameter (u can set 'any' as inerface name but it work not so fine):
|
|
```bash
|
|
./fastnetmon br0
|
|
```
|
|
|
|
Example program screen:
|
|
```bash
