Sorry, I sent a fairly large email to the group and I am not sure if it got
bounced. It was a mini how to . this email is just to see if my @#$%@#$%$
server is working.
LOL
This has taken me quite some time to do this as I come from the Windows
world. Getting into the Linux world was quite a jump. (Now the rant) First
I would like to say that if some of the people in the Linux world had better
documentation and most importantly keeping it current with the releases of
software it would cut down on development time.
I use Konqueror for getting around the Linux System like using windows file
explorer except better. Open up a Konqueror and press F9 that will open a
side bar of file management. F4 is to open up a command shell in the
directory that you are in.
This is based on the compiled from src Stable Version Of SER 8.14 Located
Here ftp://ftp.berlios.de/pub/ser/0.8.14/src/ put this in the very root of
the hard drive (this should keep all the paths correct . don't change the
name of the directory from sip_router)
I am running Fedora Core 3 Distribution Located here
http://download.fedora.redhat.com/pub/fedora/linux/core/3/i386/iso/ there
are 4 iso's (FC3-i386-disc1-4.iso) which are bootable.
Make sure that MySQL is enabled (make sure you check it off when
installing) along with PhPMySQL I installed the Server Packages from the
list.
I also installed Webmin located here http://www.webmin.com/ for remote
access via a M$ machine.
Compiling the SRC code was a bit problematic for me (Note that there is an
Install Doc error when making the bin distro you will need to go into the
MakeFile and comment out the line at the bottom) it is only documentation.
You will see this as soon as you use the gmake utility.
You will first need to edit the Makefile in the module of ACC
locate this line
# uncomment the next line if you wish to enable SQL accounting
DEFS+=-DSQL_ACC
This is the way it should look uncommented. Now save it. Lol
Open up a command shell in the sip_router directory.
Type the following
gmake all mode=debug exclude_modules="" modules
you will get some errors that are caused by the imcompleteness but not to
worry you won't be using them ..
It will should come up with "ser-0.8.14_linux_i386.tar.gz" you will need to
do a find for this file because I have no idea where it places it so I use
Konqueror to locate it. Then do a copy command to the Home directory so you
have it for later also.
You will need to do some reading in the manual of SER so you will be
familiar with the system. But here is a working ser.cfg using MySQL for
accounting
You will need to create the data base using the shell script in the SBIN
directory.
If you use "serctl start" and the pid file is not found then that means that
there is an error in the ser.cfg
Yes I know that the code looks ugly however so does your dog ... just
kidding . it is a work in progress as I work it down more . I hope that this
will help a few folks out.

Hi,
I am a newbie to SER. Just today I successfully set up and terminated a
call between users using a SER server running on a P4 MandrakeLinux 10.1
machine. I used the ser.cfg script that came along with the installation.
This, I understand does not allow persistent users. Since I had built my
installation with Mysql modules, I set up mysql to run along with ser by
executing the ser_mysql.sh. It went through fine and I saw that the tables
were all created too.
I modified the ser.cfg file so as to include user authentication through
mysql. My ser.cfg file is found attached herewith. As and when I restart
ser, this is the error message that I get:

I am trying to re-build a copy of sems with te lame mp3 encoder.
The build seems to complete without errors but when I try to start
sems I get "sems[2560]: Error: audio plug-in doesn't contain any exports ! "
error and sems doesn't start.
Any idea why? Any idea how to correct this?
Thanks,Steve
Hi,
I am a newbie to SER. Just today I successfully set up and terminated a
call between users using a SER server running on a P4 MandrakeLinux 10.1
machine. I used the ser.cfg script that came along with the installation.
This, I understand does not allow persistent users. Since I had built my
installation with Mysql modules, I set up mysql to run along with ser by
executing the ser_mysql.sh. It went through fine and I saw that the tables
were all created too.
I modified the ser.cfg file so as to include user authentication through
mysql. My ser.cfg file is found attached herewith. As and when I restart
ser, this is the error message that I get:
-------------

Thanks for the reply Girish.
I would just like to verify the following:
I currently have the following very simple config:
if (method == "INVITE")
{
//other code
t_on_failure("1");
};
failure_route[1]{
revert_uri();
rewritehostport("xxx.xxx.xxx.xxx:5062");
append_branch();
t_relay_on_udp("xxx.xxx.xxx.xxx","5062");
break;
}
However when I restart SER it tells me I have an error in my ser.cfg
and from the log file it says I am missing a loadmodule:
The following are the load modules I have inclued. Am I missing one?
sl.so
tm.so
rr.so
maxfwd.so
usrloc.so
registrar.so
nathelper.so
textops.so
auth.so
authdb.so
Thanks,
Aisling.

I installed ser09 with mysql.so and acc.so and tried to implement serweb
(latest version fetched by CVS this night).
Unfortunately, the generated SQL statements do not fit to the actual
implementation of the database:
log errors for example:
Unknown column 't1.caller_deleted' in 'where clause'
Table 'ser09.uuidaliases' doesn't exist
I use Slackware 10 with kernel 2.6.10, PHP 4.3.9 (5.0.3 did not work
with serweb) and MySQL 4.1.8 and I know that the DB-model of ser09
differs from the model of ser0814.
Where can I therefore get the latest version of the DB-model ?
kind regards and thank you for your help!

Hello all,
I'm using serweb CVS rel_0_8_12 and SER ser-0.8.14. SER works fine
and serweb admin works - but if I try to click account in the admin
panel it hangs - or if I try to use the user_interface it will hang on
login. Has anyone had a similar problem? Reg Globals is On ect...
.followed the inst in the INSTALL file.
Thanks,
Patrick
After doing a small bit of testing I have a bit more information
which may help identify the problem....Basically I think the problem
comes down to nat.
I still get the rtp errors mentioned below in the var/log/messages
file whether voice works or not(strangely enough)...but here are the
scenarios that work and dont work:
I have ser and asterisk on a private natted network. They are reached
via a router which has a public address and does port forwarding. One
my clients(a bt100 hardphone is also on this lan but registers with
ser throught the public address anyway...so my understanding is that
the bt100's sip register message goes out onto the internet and back
in again.
Now if the bt100 rings a client (e.g. xlite or windows messenger)or
vice versa that are also on this lan...the call works and voice is
transmitted (even though they again register through the public
address by routing their sip messages onto the internet and back in
again). However if the bt100 tries to ring a client not on the lan
(on another network which may or may not be behind nat)...np voice is
transmitted....Surely this is a nat problem even through the rtp
errors are being displayed??....
If anybody has any idea how to fix this or if any more information is
required in order to troubleshoot please let me know. Like I
mentioned before this must be demoed next week...This natting
scenarion worked when clients registered direct to asterisk so i
presume its possible with ser.
Thanks in advance,
Aisling.
