Hi, I have installed SER on a RedHat 9 machine and it seems to start OK, however it does not seem to open port 5060 to receive messages. The following is the debug from the console - the line "0(0) init_unixsock_socket: No unix domain socket will be opened" does not look good. Any ideas? Thanks, Adrian Levin Some of the debug produced on the console: Listening on udp: 127.0.0.1 [127.0.0.1]:5060 udp: 217.155.103.17 [217.155.103.17]:5060 tcp: 127.0.0.1 [127.0.0.1]:5060 tcp: 217.155.103.17 [217.155.103.17]:5060 Aliases: tcp: dsl-217-155-103-17.zen.co.uk:5060 tcp: localhost:5060 tcp: localhost.localdomain:5060 tcp: HAL:5060 udp: dsl-217-155-103-17.zen.co.uk:5060 udp: localhost:5060 udp: localhost.localdomain:5060 udp: HAL:5060 WARNING: no fork mode and more than one listen address found(will use only the the first one) 0(4667) fm_malloc_init: F_OPTIMIZE=16384, /ROUNDTO=2048 0(4667) fm_malloc_init: F_HASH_SIZE=2067, fm_block size=16548 0(4667) fm_malloc_init(0x42133000, 33554432), start=0x42133000 0(4667) shm_mem_init: success 0(0) core dump limits set to 4294967295 0(0) DEBUG: init_mod: sl_module stateless - initializing 0(0) DEBUG: register_fifo_cmd: new command (sl_stats) registered 0(0) unixsock_register_cmd: New command (sl_stats) registered 0(0) unixsock_register_cmd: New command (ul_add) registered 0(0) unixsock_register_cmd: New command (ul_show_contact) registered 0(0) DEBUG: init_mod: registrar 0(0) WARNING: using only the first listen address (no fork) 0(0) DBG: open_uac_fifo: opening fifo... 0(0) DEBUG: FIFO created @ /tmp/ser_fifo 0(0) DEBUG: fifo /tmp/ser_fifo opened, mode=432 0(0) init_unixsock_socket: No unix domain socket will be opened 1(0) DEBUG: init_mod_child (-1): tm 1(0) DEBUG: callid: '6fe7fef8-0(a)127.0.0.1' 1(0) DEBUG: init_mod_child (-1): usrloc I am using the default configuration file - with the port number un-commented out, although I have tried with it commented and it seems to make no difference.
