Installation (OS agnostic)
[Install Guide http://www.openser.org/docs/INSTALL
]Read first carefully the INSTALL file, paying especially attention to section 3C) and 3D).
| Info | ||
|---|---|---|
| ||
There are several packages ready to be installed. Packages are available for Debian, Fedora, FreeBSD, Gentoo, NetBSD, OpenBSD, Solaris. |
| Tip | ||
|---|---|---|
| ||
If you need a newer version. Make packages by typing 'make deb' or 'make rpm' instead of 'make install'. |

| Warning | ||

If you get the following error when registering: <Message too big> then probably your host forwards the SIP Message to itself. So trace on localhost to see if this is the case. If your server has more than one DNS entry, make sure that you have all hostnames in /etc/hosts and that you have the following line in your openser.cfg alias="yoursipdomain.ch:5060" |
Troubleshooting with the xlog module
For debugging purposes, it may be very helpful to use the xlog module, which logs directly with syslog.
Add the following line to the /etc/syslog.conf file:
| Code Block |
|---|
# OpenSER messages # make sure this spacing is done with tabs, spaces may cause errors local7.* /var/log/openser # remove local7 from syslog and messages *.*;auth,authpriv.none,local7.none -/var/log/syslog *.=info;*.=notice;*.=warn;\ mail,news.none,local7.none -/var/log/messages |
And add the following line to the openser.cfg:
| Code Block |
|---|
log_facility=LOG_LOCAL7
;Add the xlog module:
loadmodule "/usr/lib/openser/modules/xlog.so"
|
It is particular helpful for logging variables. You can add e.g. follwing line at the beginning of the default route.
| Code Block |
|---|
xlog("L_INFO", "request method: [$rm], from URI: [$fu], To URI: [$tu]");
|

Control server with openserctl
With sudo openserctl moni you can monitor the state of your openser (whether it is actually running after the installation)
openserctl is located in /usr/sbin, which is not by default in the user PATH. To use openserctl as a non-priviledged user you need to add the path to the environment export $PATH=PATH:/usr/sbin or call with the full path /usr/sbin/openserctl. Addionally you have to change permissions for the fifosockets. Add the following line in /etc/openser/openser.cfg
| Code Block |
|---|
sock_group="staff" # openser socket/fifo group, e.g. staff
|
If you don't want to type the read/write password every time you make a change via openserctl, you can add the following lines to your /etc/openser/openserctlrc. This is also a good moment to configure the SIP domain.
| Code Block |
|---|
## password for database read/write user
DBRWPW=openserrw
## your SIP domain
SIP_DOMAIN=yoursipdomain.ch
|
Be aware that this can be a security problem, as your password is unencrypted in a file. However, this might be anyway the case in /etc/openser/openser.cfg.
