It's a test task repo for Sirin Software. The application is a packet sniffer that performs incoming packet stats collection. The sniffer is composed of daemon and CLI (for interaction with daemon and stats printing).
Building the sniffer is pretty straightforward:
$ makeCleaning built files:
$ make clean"sniffcon" program is a CLI for daemon control. Usage:
$ ./sniffcon <command/--help> ...Possible commands:
- start [iface] — starts the daemon on "iface" (or the current interface, if omitted)
- stop — terminates daemon process (and flushes stats to disk)
- show [ip] count — shows count of received packets for an IPv4 address "ip"
- select iface [iface] — switches interface being sniffed to "iface"
- stat [iface] — prints stats for packets on "iface" (or globally, if omitted)
- reset — resets packets stats
- --help — prints this message
Running daemon is also possible by just running "sniffer" executable:
$ ./sniffer [iface]
