http://wikipbx.wikidot.com/forum/t-233617/problems-getting-0-8-running-on-debian

but because I am new to all this, I get all kinds of errors maybe someone could shed some light on how to implement the solution correctly. Here is what I have done so far:

1)Downloaded Swig and unzipped into /usr/src/swig-2.0.0
2)Ran ./configure ( I am not sure what options if any I should put when running configure, I just ran without any)
3)When I try to run "make install" I get:

/usr/src/swig-2.0.0/Tools/config/install-sh: swig does not exist.
make: *** [install-main] Error 1

4)So I went to /usr/src/freeswitch/src/mod/languages/mod_python and tried to run "make reswig" here is what I got:
wikipbx:/usr/src/freeswitch/src/mod/languages/mod_python# make reswig
rm -f mod_python_wrap.* freeswitch.py
which swig 2>&1 »/dev/null && swig -python -c++ -I../../../../src/include -oh mod_python_wrap.h -o mod_python_wrap.cpp mod_python.i
make: *** [mod_python_wrap.cpp] Error 1

I'm sure I missed a step or a few steps, but any and all help is greatly appreciated.

thanks a lot

-The last 3 lines happens when I actually load Freeswitch, not when restarting apache
-Also I actually compiled Python 2.5.5 but its shown here as 2.5.2, don't know if that makes a difference at all

2. Add these lines to the end of VirtualHost section in /etc/apache2/sites-available/wikipbx:

  <Directory /usr/src/wikipbx-0.8> Order allow,deny Allow from all </Directory> 

Restart apache.

3. Are there any errors displayed when apache is started?

I'm hoping someone might see an obvious error somewhere in the config files.

[ERR] mod_xml_curl.c:304 Received HTTP error 404 trying to fetch http://wikipbx.myserver.net/xml_dialplan data: [hostname=wikipbx.myserver.net&section=configuration&tag_name=configuration&key_name=name&key_value=post_load_switch.conf]

I don't seem to be getting any errors when loading apache. Any more pointers would be appreciated. I have scoured the net for similar issues but non seems to apply to my situation. Help por favor!

As for your questions:

1. You don't need to copy anything to /var/www dir. The "templates" directory is used by wikipbx internally, it's not meant to be displayed by the web server directly.

2. You don't need to create that file. Once you have mod_wsgi and wikipbx configured, freeswitch would be receiving necessary configs from that URL.

I noticed a folder called "templates" inside of wikipbx-0.8/wikipbx/wikipbxsweb.
1)which steps when installing wikipbx does the files inside this templates folder get copied to maybe a /var/www/ folder? Or I have to do that manually? I am finding that after I followed all the steps, when I go to my wikipbx.myserver.net, I'm still loading the default "It works".
However for just the heck of it, I copied all the files from this templates folder into a /var/www/xml_dialplan and when I go to wikipbx.myserver.net, something does come up, its just that there are errors, which leads me to believe that there is a step I am missing or I am doing wrong.

2)In this file:
/usr/local/freeswitch/conf/xml_curl.conf.xml,
I see this line:
<param name="gateway-url" value="http://wikipbx.yourserver.net/xml_dialplan/" bindings="configuration,dialplan,directory"/>
do I create this "xml_dialplan" manually or it should be created on one of the steps when setting up wikipbx?

This is probably quite easy for you guys, but I have tried different novice tricks that I know with no luck, any and all help is sincirely appreciated.

Since there are more than two people working on wikipbx codebase, I think that we should stick to a bit more disciplined approach for commits. There are various ways to organize workflows, I'm thinking about something inbetween "Decentralized with shared mainline" and "Decentralized with human gatekeeper". Unless it's a trivial change that can be committed directly to trunk by anyone, it should go through the following stages:

1. Create or select existing bug or blueprint. If it's been created, wait for some feedback.
2. Make a branch for this task. Link the related bug/blueprint to it in LP interface.
3. Hack, hack, hack.
4. When it's ready, it should be reviewed by someone (not the person who wrote the code). If there's something to be improved, go to #3.
5. Merge with trunk and/or stable branch.

Things to look for during code review:

1. Python coding style violations.
2. Things that can be improved.
3. Errors, typos.
4. Possible unexpected effects from the new code.

 Each sip profile is its own ip/port bindings, so yes, you must use different ip or port for each profile. 

Looks like it's sufficient for each profile to listen on its own socket. It's rather uncommon to have such configuration as most people just use different port numbers for different profiles, but it's not hard to implement.

But we can get another issue here. After adding multi-tenancy to wikipbx Traun noticed that that one of the gateways was using his server's IP instead of domain name for making incoming calls. We've got a workaround for authenticating such calls - domain name is specified in SIP request parameters that are received in SIP invite later. However, we won't be able to use that parameters for filtering channels as they aren't available in freeswitch command's response. In this case, it's still better to be too restrictive than too permissive, but I'd prefer to have something that always works correctly. One thing I haven't thought before is replacing IP with domain in channel variable after applying domain hack - this could work in theory.

It seems to me the only common part in these channels is DCext profile name. So if every tenant has its own profile, channels can be filtered by profile.

Channels 1 and 4 can be filtered by domain name, but then channels 2 and 3 wont be visible in any Account.

Probably the same approach should be applied to CDRs for the cases where right now we raise an error:
"Cannot associate this CDR with an account. Did not find either a valid account_id or domain_name channel variable"

On a serious note, github is intended for hosting code rather than developing software projects, so it doesn't offer much besides a fancy UI for forking git repos. What's missing: release planning and localization. This also leads to oversimplified issue tracker that most people don't use.

As a bonus, you can host packaged software in PPA, which I'll probably do for 0.9.

I mean github has a ton of momentum, it seems like a better time investment to learn git/github.. what do you think? What are the major benefits of launchpad over github?

I've already created a branch there a few days ago, although I was going to use it only for translations initially. I'll post a message with more details in this forum when it'll be ready for development, stay tuned.

Is there any particular targets set for the new version?
What new functionality are planed for the new version?

The next version will work with a recent version of Django plus some other minor tweaks like UI improvements

How far are the project right now from the next release?

Its about 90% there

What is the best way to contribute to wikipbx project?

There's currently not really a good way .. if you have code patches send me a private message and we can discuss over email. Eventually I think DVCS might be the best approach.

How stable is the current trunk version? Can it be used in production, if not what areas are not stable yet.

Its stable, I can't think of any areas where it will blow up on you..

I'm also thinking that DVCS is much more appropriate, because that way people don't have to send in patches which puts pressure on us to review .. with DVCS people who want to submit patches can just fork it and we will pull the (good) changes.

I think it makes sense to move everything somewhere else :)

Someplace that ..

• Free for open source projects
• provides DVCS, ideally git IMO
• Nice issue tracker
• Forum / Wiki

As there are just two developers and we work on it in our free time, we don't have any deadlines except "when it's ready".

The primary goal for the next release was to get wikipbx running on modern version of django and it's been completed. However, we don't consider trunk production ready yet as it hasn't been extensively tested and there are some more features planned.

However, there must be other less obvious ways for malicious user to exploit freeswitch server as he has direct access to generated dialplan. We plan to have a WYSIWYG interface for editing dialplan extensions in the future that would let user to use only safe commands.

 sofia/gateway/<gateway_name>/<dialstring> 

Note that gateway name doesn't have to be the host name for the SIP gateway. It can be any string identifier. The host name is taken from the "realm" field that is set to gateway name by default. In your case, every user should have unique gateway name, but they can have the same realm name with different username/password.

There's some chance that freeswitch docs are incorrect and it requires a unique socket rather than port as you suggest. You could test it by removing "unique=True" from wikipbx.wikipbxweb.models.SipProfile.sip_port, creating a new database with wikipbx models and running freeswitch with multiple SIP profiles sharing the same port number but with different IPs.

I'm new to this project and would like to find more about its development.
Could developers share the current status of wikipbx development. I'm interested in the following aspects:

Is there any particular targets set for the new version?
What new functionality are planed for the new version?

How far are the project right now from the next release?

What is the best way to contribute to wikipbx project?

How stable is the current trunk version? Can it be used in production, if not what areas are not stable yet.

Thanks!

Is there any plans to adjust this?

It configures extensions with the line like this:
<action application="bridge" data="sofia/gateway/myprovider.com/$1"/>

After that it's possible to edit this line and specify another gateway (e.g. gateway of another account)

Is there any control that every account can use only his own gateways and not gateways of other accounts?

It seems to me that in multi tenant install accounts should not be able to see and control calls of other accounts.

Is it a bug or feature?

I'm looking on this system from multi-tenant point of view.
In this case one account should be able to name his gateways as he wants. And should not depend from the names that already in use by other accounts.

E.g. When some provider provides hosted PBX service it's expectable that he'll be a gateway for them too.
They'll be using the same "Gateway Name:" "providername" and different "Username:".

May be I miss something and it was done intentionally?

If tenants have their own IPs it should be possible to allow them to have own profiles and to accept connection on 5060.

1. I've installed latest SWIG (2.0.0)

2. Rebuild SWIG generated files in libs/esl/python directory:
make reswig

3. Then in libs/esl/ directory:
make clean; make pymod

After that wikipbx was able to call ESL functions properly.

logger.info("creating eslconnection %s %s %s" % (socket.listen_ip, str(socket.listen_port),socket.password))
con = ESL.ESLconnection("localhost","8021","ClueCon")
if con.connected:
logger.info("connected")
else:
logger.info("NOT connected")
yield con

Today after booting computer and starting wikipbx I was able to load several pages where get_fs_connections() being used (Endpoints Manage, Gateways Managed).
Apache logs looks like this:

[Mon Jun 14 05:56:27 2010] [error] get_fs_connections()
[Mon Jun 14 05:56:27 2010] [error] 1 eventsockets
[Mon Jun 14 05:56:27 2010] [error] creating eslconnection 127.0.0.1 8021 ClueCon
[Mon Jun 14 05:56:27 2010] [error] connected
[Mon Jun 14 05:56:27 2010] [error] get_fs_connections() done

After few clicks in wikipbx interface get_fs_connections() stops working and in apache logs I have:

[Mon Jun 14 05:56:33 2010] [error] get_fs_connections()
[Mon Jun 14 05:56:33 2010] [error] 1 eventsockets
[Mon Jun 14 05:56:33 2010] [error] creating eslconnection 127.0.0.1 8021 ClueCon

Now every click on "Calls Live", "Gateways Manage", "Endpoints Manage" just hangs, without producing any output or error logs.

After that I've tried FreeSwitch ESL sample scripts freeswitch-1.0.6/libs/esl/python/events.py and its working fine everytime I'm starting it.
It has the same kind of code:

con = ESLconnection("localhost","8021","ClueCon")
#are we connected?
if con.connected:
print "connected"
con.events("plain", "all");
….

FS 1.0.6.

This problems happens with any page that is calling get_fs_connections(). E.g. (live calls, manage account, manage gateways…)
ESL.ESLconnection(…) from fsutil.py doesn't connect. The code stuck on this function and doesn't go any further.

I wasn't able to solve this issue so far.

Validating models…
0 errors found.

Django version 0.97-pre, using settings 'wikipbx.settings'

Do I need to change anything?

models.CharField

<class 'django.db.models.fields.CharField'>

It looks like you have some problem with python installation that causes invalid imports. There are two objects called CharField that we import from django and I don't see how can importing any of them can cause that exception that you get. As a test, you may try running ./manage.py shell and entering:

 from django import newforms from django.db import models newforms.CharField models.CharField 

Does any of those lines give you an error?

I used the following details

wikipbx —> 0.8
Django —> trunk revision 5024 ( It is suggested in the installation manual).
mod_wsgi —> 3.1

NOTE: I have not include any DNS here . I had bit exposure of Django so I just ran
python manage.py runserver <IP:PORT>

Then used the IP:PORT in my browser.

Will it cause any error?

Thanks in advance……

1. You use wikipbx 0.8 release and not the trunk version. The latter won't work with current installation instructions.

2. You use the correct version of django, as specified in install guide.

The error message looks incomplete, was there any other useful info like the exact line where the error appeared?

Tried index in module wikipbx.wikipbxweb.views. Error was: 'module' object has no attribute 'CharField'

Any help would be appreciated.

Which version of mod_wsgi do you run? It looks like there's some change with its configuration directives, otherwise I don't understand why WSGIPythonPath didn't work.

I followed the steps. I didn't get any error. My python version is 2.6.
I copied libs/esl/python/ESL.py & _ESL.so to /usr/local/lib/python2.6/dist-packages/ and error is solved.
have I done any mistake with that ? is it correct ?

 python --version 

2. Make sure ESL library is built:

 ls /usr/src/freeswitch/libs/esl/python/_ESL.so 

Looks like that's the case, but an extra check won't hurt.

3. Run python with PYTHONPATH environment variable used for wikipbx:

 PYTHONPATH=/usr/src/wikipbx:/usr/local/lib/python2.6/dist-packages/django:/usr/src/freeswitch/libs/esl/python python2.6 

Execute this command:

 import ESL 

Do you get any errors?

But still same error

ViewDoesNotExist at /
Could not import wikipbx.wikipbxweb.views. Error was: No module named ESL

My django install in this /usr/local/lib/python2.6/dist-packages/ & freeswitch & wikipbx stored at /user/src

My file /etc/apache2/site-available/wikipbx
