Hi,all I'm not clear about two things. 1) in the file freeradius-server-2.1.3/src/mainradiusd.c, at the line 103-105: 103 #ifdef OSFC2 104 set_auth_parameters(argc,argv); 105 #endif what's this checked for ? it's about security or something? 2) in the file freeradius-server-2.1.3/src/main/event.c at line 2874: why ,it check the pointer el and not pl ? 2859 /* 2860 * Externally-visibly functions. 2861 */ 2862 int radius_event_init(CONF_SECTION *cs, int spawn_flag) 2863 { 2864 rad_listen_t *this, *head = NULL; 2865 2866 if (el) return 0; 2867 2868 time(&fr_start_time); 2869 2870 el = fr_event_list_create(event_status); 2871 if (!el) return 0; 2872 2873 pl = fr_packet_list_create(0); 2874 *if (!el) return 0;* *why not check pl?* 2875 i am a newbie, thanks everyone!!!
