Hi All,
I am new to SER. I might just made some simple mistakes. So be easy
on me:) I appreciate any inputs.
Basically I was able to install and run SER 2.0.0 RC1 and make call
between SIP clients SJPhone 1.65 with a helloworld configuration. Now
I am trying to add the Authentication and MySQL. Here are what I did
so far and no luck to get it work:(
1. Generate the configuration files with configuration file
buildsystem and the content of the file is in the bottom of this
message.
2. Create the SER database in MySQL server by running the ser_mysql.sh
create command
3. Set SIP_DOMAIN variable: export SIP_DOMAIN="unknown.org"
4. Add domain and user with SER_CTL 2.0 with following commands
ser_ctl domain add unknown.org
ser_ctl user add 777 at unknown.org -p 1212
The ser_ctl domain show and user show return:
unknown.org unknown.org --------w--c-s
777 at unknown.org uri 777 at unknown.org
777 at unknown.org credentials username=777 realm=unknown.org password=1212
777 at unknown.org attr datetime_created=2008-04-06 03:25:43
I believe this should set the user and domain correctly to the database.
But I also got some weired output with other command like ser_ctl
ps, ser_ctl version. Same error:
ser_ctl: (97, 'Address family not supported by protocol'): error'>
And sercmd also give me the follow errors:(
ERROR: connect_unix_sock: connect(/tmp/ser_ctl): Connection refused [111]
5. Run the ser with error to console and no fork.
6. Configure the SJPhone with above registration information.
The client can not register and got 401 Unauthorized response. Below
are the SIP packets contents:
