man traffic-collector (Administration système) - Collect and summarise network traffic
NAME
traffic-collect - Collect and summarise network traffic
SYNOPSIS
traffic-collector [-tpVh] [-i, --interface interface] [-f, --filter bpf-filter] [-r, --read-file tcpdump-file] [-s, --summary-file output-file]
DESCRIPTION
traffic-collect is a network traffic collection and summary tool. When executed traffic-collect will detatch from the terminal, place the specified interface in promiscuous mode (unless told otherwise) and begin collecting packets.
traffic-collect will execute until interrupted with a SIGTERM, SIGINTR or SIGHUP whereupon it will gracefully exit. If traffic-collect is interrupted with a SIGUSR1 it will write a report to the output file specified. On recipt of a SIGUSR2 it will write a report and then delete its state.
The report lists traffic per host, total network traffic and which hosts communicated and with whom. The report is not intended for human consumption, rather to be passed through one or more of the traffic-vis sort tools and a frontend formatter.
traffic-collect can also accept tcpdump style packet filter descriptions and read packet dump files generated by tcpdump
OPTIONS
- -p, --no-promisc
- Do not put the interface into promiscuous mode.
- -i, --interface interface
- Use interface instead of default.
- -f, --filter filter
- Use bpf / tcpdump filter to screen packets.
- -r, --read-file file
- Read a tcpdump packet trace file instead of listening on a live interface
- -s, --summary-file file
- Write report to specified file instead of default.
- -t, --timestamp
- Append timestamp of '.YYYYMMDD-HHMMSS-XX' to summary filename when writing files.
- -V, --version
- Display version information and exit
- -h, --help
- Display version information and exit
EXAMPLES
The simplest example:
- traffic-collect
Will listen on the first available interface with no packet filter and report to the default output file.
This example uses a BPF packet filter to ignore all traffic except SMTP:
- traffic-vis -f "tcp port 25"
Every option has a corresponding long option, this can make commandlines much more readable:
- traffic-vis --filter "tcp port 80" --summary-file /tmp/foo.tc
