[Serusers] problems when starting ser

Hello all, I have installed ser in Ubuntu Karmic by means of Synaptic without any problems or errors during the installation. But before starting to configure the ser.cfg, I decided firstly to try the configuration by default and I got this error (I only uncommented the "log_stderror=yes"): cng@cng:/etc/ser$ ser D E Listening on udp: 127.0.0.1 [127.0.0.1]:5060 udp: 10.1.3.207 [10.1.3.207]:5060 udp: 192.168.50.10 [192.168.50.10]:5060 tcp: 127.0.0.1 [127.0.0.1]:5060 tcp: 10.1.3.207 [10.1.3.207]:5060 tcp: 192.168.50.10 [192.168.50.10]:5060 Aliases: tcp: cng.local:5060 tcp: cng:5060 tcp: localhost:5060 udp: cng.local:5060 udp: cng:5060 udp: localhost:5060 0(2956) init_tcp: using epoll_lt as the io watch method (auto detected) cng@cng:/etc/ser$ 0(2958) Maxfwd module- initializing 0(2958) ERROR: fifo_server.c:857: Can't create FIFO: No such file or directory (mode=384) 0(2958) ERROR: ctl: mod_init: init ctrl. sockets failed 0(2958) init_mod(): Error while initializing module ctl ERROR: error while initializing modules It seems that it starts ok but suddenly finds an error and stops.

I am a little bit confused. Where is the problem? Thanks in advance, Rebeca Martinez
