Passes the arguments to netotter() and returns its exit code

netotter(): the startup sequence, the CLI and interactive loops, and the cleanup at exit

netotter_new

netotter_t *netotter_new(void)

Calls: filter_args_free, filters_clear, local_addrs_free, hostmap_free, renames_free, reverse_free, anomalies_free, plist_destroy, store_free, queue_purge, my_out_free
Library and system calls: close, free

enable_from_list

static int enable_from_list(lib_common_t *os_lib, char *if_list)

Enables every interface of the comma-separated id list (-i). 0 on success, 1 on the first id that can't be enabled.

Called by: netotter
Calls: my_putstr, my_strtok, tab_free, str_to_id, toggle_ifname, get_ifname_state, toggle_ifname, get_ifname_state

on_sigint

run_cli

static void run_cli(lib_common_t *os_lib, netotter_t *netotter)

src/entry_point/netotter.c:118 · static · both builds

CLI mode: ticks on the interfaces given by -i until Ctrl-C, then prints the packet list. Without -i (only -I), there is nothing to capture: the loaded packets are printed (and saved with -O) right away.

Called by: start_program
Calls: raw_to_f, local_refresh, anomaly_tick, anomaly_report, anomaly_stats, capture_full_check, display_packets, my_putstr, my_write, tick, my_usleep, tick, my_usleep

run_interactive

static void run_interactive(lib_common_t *os_lib, netotter_t *netotter)

src/entry_point/netotter.c:143 · static · both builds

Interactive mode: ticks every TICK_US like the CLI mode, while waiting on stdin for interface ids and commands. q, end of stdin or Ctrl-C exits.

Called by: start_program
Calls: print_commands, handle_key, raw_to_f, display_enabled_itrf, local_refresh, reverse_tick, anomaly_tick, capture_full_check, if_tab_display, my_putstr, tick, stdin_wait, tick, stdin_wait
