Hello, I've installed kamailio 1.4.3 (without tls) on ubuntu by following the provided INSTALL guide. I want to use it as a presence server but i've got some problems starting it. "kamctl start" returns nothing. and "kamctl moni" returns "Error opening kamailio's FIFO /tmp/kamailio_fifo" I've checked in my .cfg file and the 'loadmodule' and 'modparam' lines related to mi-fifo module are uncommented. I've checked also the mi-fifo module was installed indeed (mi_fifo.so appears in /usr/local/lib/kamailio/modules directory). Could anyone help please? -- Sara
