[Kamailio-Users] sipgrep as non-privileged user
by Robert McNaught 24 Sep '08

24 Sep '08

Hi, I am using sipgrep to do sip traces on an openser/asterisk. I am find this great for getting readable traces - previously ngrep was difficult to read. However, to use sipgrep, I need to be logged in as the linux root user. I can change the PATH of an admin user so that they can have access to the command but they cannot use it as they need to be root in order to gain access to see the network traffic. Does anyone know of a way to do this? Is it normal to have engineers continually log in as root to take these traces - it seems awful dangerous? I know you could log in as a non-prileged user and put in sudo sipgrep -f xxx -t xxx, but not sure if people are actually doing this in production systems, or have a workaround? Thanks Robert

[Kamailio-Users] new feature: generic shared container in config language
by Elena-Ramona Modroiu 24 Sep '08

24 Sep '08

Hi, I just committed a new module: htable http://www.kamailio.org/docs/modules/devel/htable.html It adds a generic hash table container for usage in configuration file. The hash table is in shared memory, therefore the values are global over all kamailio processes. The items in hash table can be accessed via $sht(name). The name can include pseudo-variables that will be evaluated at runtime. In this way, the hash table can be used to store data per user and can offer functionality of dealing with array of values. An example of how to protect against dictionary attacks is in the README (link to online version above). As another example, loading values in hash tables from AVPs and building an array: $var(i) = 0; while($(avp(s:tmp)[$var(i)]) != NULL) { $sht(tmp[$var(i)]) = $(avp(s:tmp)[$var(i)]); $var(i) = $var(i)+1; } As a roadmap for the new module, planned for addition: - MI commands to get/set items in HT - ability to save/load in/from database - ability to init items at startup - auto-expire time for items This completes global variables space along with shared variables ($shv(name)) which are single value and allow only static name, but they are faster to access (see cfgutils readme file for more details on $shv(name)).

[Kamailio-Users] openser.org and project documentation
by Jeremy McNamara 23 Sep '08

23 Sep '08

Whoever has taken over openser.org should do the community as a favor and at the very least HTTP 301 redirect the documentation links over to kamailio.org. There are soo many sites that index URLs like: http://openser.org/docs/modules/ ...however openser.org gives back a 404 not found.

[Kamailio-Users] About Changing URI's
by Ali Jawad 23 Sep '08

23 Sep '08

Hi I have the following setup Cell Phone "Any Possible Number" ----Calls a DID number-----> DID Provider --> Forwards Call to my Openser --> OpenSer Server--> Forwards Call to Asterisk with A2B --> Forwards it to the cell phone of the user In short, a person can call a DID and it gets forwarded to Openser, if the user is online using his sip phone, the sip phone rings and all is OK. However, if the user is not online I do forward that call to Asterisk and I want to forward it to the cell phone of the user. The problem is that the FROM field and the SOURCE URI keep changing,they are in the from phonenumberOfCaller(a)DID_Service_Provider.com and I do want to charge the user for the call. To do that I need to have the FROM field and the source URI to be the USER ID so that I can charge him for the call. So, I might have to change the source URI and FROM field of the packet and send it to asterisk..it would send the packet back to Openser and I have to change those back to what they were and then send it to the DID provider. Might sound confusing, and it might sound stupid. Please help me set this straight, can it be done ? Maybe not ? Maybe Yes... Any suggestions are welcome.

[Kamailio-Users] un-subscribing a pending subscription is also pending
by jh＠tutpro.com 23 Sep '08

23 Sep '08

a user complained that un-subscribing a pending subscription is also pending, i.e., kamailio responds with 202 instead of 200. i verified the behavior. now the question is, what do the relevant RFCs say about it? it appears logical to me that if a user gives up waiting to get his/her subscription confirmed, he/she should be able to forget the whole thing by sending an un-subscribe. any comments on this? -- juha

Hi all, it is possible to use CDRTool 6.6.3 or 6.6.4 with freeradius-cdrtool-1.1 ? The problem is in the code of freeradius-cdrtool.py, where in the code have "DebitBalance From=%s To=%s Duration=%s\n" , "MaxSessionTime From=%s To=%s Duration=%s Lock=1\n" and others, but the newer CDRTool need have a gateway parameter and Call Id parameter. Anybody have a sucess with this versions ? Thanks in advanced, Diego.

Re: [Kamailio-Users] nested redirect

Hello, what you sent is the debug from kamailio/openser, which is useful, but I would need the sip messages, you can use ngrep for that, do ngrep -d any -qt -W byline port 5060 on your openser/kamailio server and send the output.
