[Serusers] OPTIONS method
by lgfausak＠august.net 14 Mar '03

14 Mar '03

What, if anything, should the SER server do with a OPTIONS method? I am receiving this method, from a phone, right after the phone makes a conversation. That is, the final ACK is sent from the phone and a call is in progress when the phone decides to send an OPTIONS message. I thought OPTIONS was a pre-call sort of thing, not for the current call. Anyway, I thought I could just capture the OPTIONS method and send a 486 busy reply with sl_send_reply(). Didn't work. ---greg

[Serusers] Behaviour of SER with private parameters in request URI
by David.Rio＠alcatel.fr 13 Mar '03

13 Mar '03

Hello all I am using SER as a proxy server. Please let's consider the following scenario 1/ Step 1 A UAC registers to SER --------- | SER | --------- ^ | REGISTER for 'service(a)logical-element.domain' contact 'service@host' | | --------- | UAC | --------- 2/ Step 2 Another UAC tries to reach the previously registered user BUT WITH PRIVATE PARAMETERS in request URI ---------- | UAC | ---------- | | INVITE service(a)logical-element.domain;param1=value1;param2=value2 v --------- | SER | --------- | | INVITE service@host (sol 1) | or INVITE service@host;param1=value1;param2=value2 (sol 2) v --------- | UAC | --------- The translation from service(a)logical-element.domain to service@host is done in SER using 'lookup'. 3/ Problem : I observe that SER when translating the user@host part of the request URI does not recopy the private parameters, what I expected it to do. => I can not find any clear position in RFC 3261 (from my understanding of the RFC). Is it a bug in SER or does SER really implement the behaviour a standard SIP proxy should have ? Thanks for your answers -- David Rio Alcatel CIT - Rennes ASD France 33 2 99 87 47 18

[Serusers] remote connections
by Mat Harris 13 Mar '03

13 Mar '03

hi, I have just today started playing with SIPS at work and found ser fun. BTW, all the following is done with micro$oft messenger 4.6 for testing (eugh!) I have set it all up at home and am trying to connect from work. I know the connection is getting through the firewall because a tcpdump shows all the expected results, and I know that ser is running ok, because I can login from my home workstations. Does ser do any sort of access control based on ip addresses that may be causing it to reject my external connections? Also, I have set up the realm with mysql authentication and I can communicate with others on the same domain, but should I be able to communicate with other sips users of other private networks (as long as they allow it) without any configuration. Do I have to do something to make that work? cheers, and well done with a very easy to quick to install product, my boss loves it -- Mat Harris OpenGPG Public Key ID: C37D57D9 mat.harris(a)genestate.com www.genestate.com

[Serusers] new module
by Tirpák Miklós 13 Mar '03

13 Mar '03

Hi! I have writen a module, may be somebody is interested in it. It is used to determinate if a user has appropriate permission to establish a call. The permissions can be managed in configuration files very simular to hosts.allow and hosts.deny. Every value in the configuration files are regular expresions, so it is easy to define rules. Example for a rule: "^sip:361[0-9]*@abc.com$" EXCEPT "^sip:.*3@abc.com$", "^sip:.*4@abc.com$" : ALL Every PSTN endpoint beginning with 361 except those ending with 3 or 4 can establish calls with everybody. In general: from_list [EXCEPT from_list] : to_list [EXCEPT to_list] from_list and to_list are comma separated expressions Expressions are treated as case insensitive POSIX Extended RegularExpressions. Keyword ALL matches any expression. -- --------------------------------------------------------------------------- Miklos Tirpak Computer and Automation Research Institute e-mail : mtirpak(a)sztaki.hu of the Hungarian Academy of Sciences phone : (361) 279-6011 H-1132.

RE: [Serusers] multiple registration on one user login
by Ng, Soo Sim 13 Mar '03

Hi, I am thinking of locking the user hardphone MAC Address onto Layer 2 Switch level. This way even if the user move around their phone, it will be blocked. The disadvantage is that it will create opreration nightmare and will only work in ETTx environment. In a broadband wireless environment, there may be no layer 2 switch in between the network and subsriber. There are 2 categories of subscribers. One is only want to use their home phone just like what the legacy voice network do. They won't bother to know about username/password. (For example illiterate elderly citizen). I must cater for these kind of users. Yet provide a secure environment for them. Another is subscribers who want to have more flexibility. They may have hardphone, softphone, pda, notebook who can logon everywhere in the on-net network. These users may have more than one phone number to their home per user account. These users will have to be reseponsile for their username/password. I am looking for all possibbilities and limitations there is before drawing any implementation plan. So far, my testing is working well.

Sorry, auth was excluded from compilation by default. Either update sip_router/Makefile from the repository or edit sip_router/Makefile, look for line containing excluded_modules, remove auth from it and do again make all. Jan.

[Serusers] Alternative to Mysql?
by David Beckemeyer 12 Mar '03

12 Mar '03

I'm trying to get SER up and I need auth. I'm not a Mysql user and, frankly, I'd rather not need to learn it, just to get authentication support. I wish there were a middle-ground between no-auth at all and a full-blown Mysql installation. I tried the Cookbook approach, using Dan Austin's HOWTO for setting up Mysql for SER, but the commands do not work as shown so I'm left with learning Mysql through and through to debug why those cookbook commands don't work. I'm very familiar with SIP and I want to test SER, not a new Sql server DB engine. It seems like Mysql is a distraction to that effort. Is anyone working on something like a flat-file module to replace Mysql? Any pointers for the best place to start on developing such a module (i.e. shortcuts)? Thanks, - david

[Serusers] Any progress for radius?
by Yang Xiang 12 Mar '03

12 Mar '03

Hi, I saw many changes in CVS about radius. Is there any progress for radius? The radius modules from release 0.8.10 are unfortunately not usable. It seems there will be some fundamental changes in terms of radius_auth and radius_acc. How will the new structure look? Best regards Yang
