[Serusers] Debian unstable: ser starts but socket not open

Just downloaded and installed the latest Debian unstable packages. When starting ser: ----------------- Listening on sip.neuropolis.org [212.52.166.10]:5060 Aliases: WARNING: no fork mode stateless - initializing Maxfwd module- initializing ------------------ Still I cannot connect (e.g. telnet) to 5060. The socket is NOT actually open. I guess my local Linux (Debian) config prevents ser from properly opening that socket (just dunno, how). # fuser -n tcp 5060 here: 5060 # uname -r 2.4.22 Tried low port numbers, too. Nothing. Strange that ser does not seem to complain.. Or does it? Here's a debug=7 log: http://sip.neuropolis.org/serlog.txt Some ser.cfg settings that may differ from the (latest) default stuff: --------------------- debug=7 fork=no log_stderror=no check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) listen=sip.neuropolis.org port=5060 children=2 fifo="/tmp/ser_fifo" Thanks, Luna Kid
