Having playing with for 2 weeks, I get the SER running as I want. The next things I am trying are:
1. Run SER in chroot mode with MySQL 2. Separate SER and serweb on two servers.
With 1, I have a partially successful config. When I can start SER with /usr/sbin/ser -u ser -g ser -t /var/ser, I got A. positive result if the DB connection string is "sql://ser:heslo@127.0.0.1/ser".
B. However, if I use the DB connection string as, "sql://ser:heslo@localhost/ser", I got the following error message:
Feb 16 19:46:09 sip /usr/sbin/ser[2452]: connect_db(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Fair enough, coz SER is in a chroot environment and cannot stat the MySQL UNIX socket. There is no /var/ser/var/lib/mysql/mysql.sock. But, what is the difference between localhost and 127.0.0.1 here? Both should resolve back to 127.0.0.1, right? Why one use UNIX socket and the other use DOMAIN socket? Also, should SER open the DB connection before chrooting itself?
Also, when running in chroot mode, SER cannot use DNS to resolve hostname. I get the following errors:

This is a result of doing INVITE sip:abcdefg@iptel.org SIP/2.0 from my domain. If I put an entry into my chrooted /var/ser/etc/hosts, the request goes fine. Is it because of my chroot environment (later in the mail) or I have to compile SER in static mode?
2. Have anyone successfully put SER and serweb on different boxes? There is no problem connecting to the DB. However, I'm not sure about the /tmp/ser_fifo part. I'm not a programmer and can only manage to understand php code, no programming. How do I work around the /tmp/ser_fifo when it is on another server?

And yes, the DNS is running on localhost and happily serving request.
Any comment?
Im running SER in a jail on FreeBSD. No problems there :-)

I'm running SER 0.8.12 on Fedora Core 1.
Would you mind share some of your experience? I managed to get syslog get along with SER by running syslog -a /var/ser/dev/log. The config file is the one that come with the rpm with DB connect string changed as show before.
