[Users] mysql.so missing

taipei:/usr/local/etc/openser # openser ERROR: bad config file (1 errors) /var/log/messages shows: Sep 27 19:23:16 taipei openser: ERROR: load_module: could not open module </usr/local/lib64/openser/modules/mysql.so>: /usr/local/lib64/openser/modules/mysql.so: cannot open shared object file: No such file or directory Sep 27 19:23:16 taipei openser: parse error (39,13-14): failed to load module mysql.so exists at /usr/lib64/php5/extensions/mysql.so However, a symlink does not work for that either. I use SuSE 10.1 on a Semperon (Athlon) CPU. I have installed mysql-devel. Besides this, I am confused about the openser.cfg file, which does not match the SER - Getting Started. Is there a better document available? What do I need to install to get the system running with phones behind NAT ? The document suggests many different things (Nathelper, STUN, rtpproxy and mediaproxy). Which one do I need? Is it either rtpproxy or mediaproxy? Is it in addition to STUN or Nathelper???? I also do not really know what I need. My server is on a public IP, with a second Ethernet card for the internal LAN. Where the user has his phone I do not know yet. Maybe on a symetric NAT or asymetric NAT, maybe on a public IP. For all it should work. bye Ronald (obviously confused)
