[OpenSER-Users] db_extra: the avp value does not correspond to the real value
by Bruno Machado 20 May '08

20 May '08

Hi friends. OK. People... I'm almost getting crazy. I don't understand what is happening. I already looked for an answer, but I didn't find nothing yet. I am recording 8 extra values in ACC, but the SQL command is using a weird value for one of them. So, I removed 6 of them to facilitate the analyze. Look at the code: . . modparam("acc", "db_extra", "valueA=$avp(i:15); valueB=$avp(i:16)") . . . avp_write("i:15","$avp(i:15)"); avp_write("i:16","$avp(i:16)"); if(!t_relay()) { sl_reply_error(); exit; }; avp_print(); exit; OK. Looking at these lines, I would say: "the sql INSERT command will use the value 15 for avp:15 and 16 for avp:16". Now, look at the result of "avp_print": 2(11112) INFO:avpops:print_avp: p=0xb3b4a900, flags=0x0000 2(11112) INFO: id=<16> 2(11112) INFO: val_int=<16> 2(11112) INFO:avpops:print_avp: p=0xb3b4a8e8, flags=0x0000 2(11112) INFO: id=<15> 2(11112) INFO: val_int=<15> Nice. AVP 15 has the value 15 and the AVP 16 has 16. But something is happening.... It is the insert command: insert into acc (from_uri,to_uri,sip_method...............valueA,valueB,time) values .........,'16','16','2008-05-19 12:48:38'). 16 twice!! Why? This question is running in loop inside my head. It should be "....'15','16','2008-05-19 12:48:38'.....". The openser code above is executed just once by the INVITE. I can bet this error is the like when we sum "2 and 3" and the result is "6". You look at the equation, but you don't see it at all. And, when you ask your younger brother to see, he says: "you are stupid... 2+3=5". I never had this problem. I use several avps to log in the database and it is the first time that it happens. You can see that I'M NOT CHANGING the values of the avps. Am I doing a stupid thing? Or, maybe, am I being blind? By the way, I'm using version 1.1.1. Tks people. OK. Apparently, there's nothing wrong. Abra sua conta no Yahoo! Mail, o único sem limite de espaço para armazenamento! http://br.mail.yahoo.com/

[OpenSER-Users] Authentication with LDAP databse
by Ahmed Huraimel 20 May '08

20 May '08

Hello, i am successfully integrated an openLDAP server with my openSER SIP proxy server. however i am facing a security problem. let me explain it briefly. **** Successful Registration with password save as clear in openLDAP DB **** * # Configration # - user name was stored in clear in openSER database - modparam("auth", "calculate_ha1", 1) which means the server will assume that the "password_spec" pseudo-variable contains plaintext passwords and it will calculate HA1 strings on the fly. # Senario # - after the UAC receives Authentication request he will build the response = MD5(username + MD5(passowrd) + realm + nonce) - then the server will build the challenge by searching the the user in the database and retrieving the password in clear then hash the password with MD5 build the challenge such that challenge=MD5(username + MD5(passowrd) + realm + nonce) . . - by comparing the the response the with the challenge the user will be authenticated. - *it works * **** Successful Registration with password save as MD5 in openLDAP DB **** * # Configration # - user name was stored in MD5 in openSER database - modparam("auth", "calculate_ha1", 0) which means the server assumes the pseudo-variable contains the HA1 strings directly and will not calculate them. # Senario # - after the UAC receives Authentication request he will build the response = MD5(username + MD5(password) + realm + nonce) - then the server will build the challenge by searching the the user in the database and retrieving the password in MD5 then challenge such that challenge=MD5(username + MD5(password) + realm + nonce) . - by comparing the the response the with the challenge the user will be authenticated. - *401 unauthorized !!!! ***** CONCLUSION **** *there for possible scenarios: 1- password clear + calculate_ha1= 0 ==> 401 unauthorized !!!! 2- password clear + calculate_ha1= 1 ==> Authorized 3- password MD5 + calculate_ha1= 0 ==> 401 unauthorized !!!! 4- password MD5 + calculate_ha1= 1 ==> 401 unauthorized !!!! * * ----------------------------------------------------------------------------------------- * asuumptions: *1- the password might be not hashed. if so then why modparam("auth", "calculate_ha1", ) used? does it mean that the password might be received hashed or not? *2- in scenario(2) the sip server hash the password by setting calculate_ha1= 1. if the password is already hashed in the database then scenario(3) should work unless there is a conflict with the hash. is this might be related to hash type or size?* or something else that i do not know!!! *question*: 1- why scenario(3) does not work? where might be the problem? 2- what to do if i want to change the hash algorithm used? for example i need to SSH1 instead of MD5 because nowadays MD5 is proved to be weak algorithm regards, Ahmed ALALI

[OpenSER-Users] How to install OpenSER on VMware?
by Habib, Yeasin 20 May '08

20 May '08

Hi, I am successful till the addition of voip overlay. After that I have also include the line source /usr/portage/local/layman/make.conf in /etc/make.conf. Now when I try to install openser using the command ACCEPT_KEYWORDS=!x86 emerge openser, every time I got the following reply back from the console emerge: there are no ebuilds to satisfy "openser" Does anybody know how I can solve this problem and install and configure OpenSER on top my OpenIMSCore Best regards Yeasin Habib You can install layman, add voip overlay and install OpenSER using standard gentoo way (emerge openser) 1) start OpenIMS image 2) Login 3) emerge --sync. On this step emerge will download information about all packages. Maybe about 200 mb 4) emerge layman 5) edit make.conf 6) add voip overlay (layman -a voip) 7) install openser (ACCEPT_KEYWORDS=~x86 emerge openser) On Tue, Apr 22, 2008 at 9:53 AM, Rob <otrebor79 at alice.it<https://lists.berlios.de/mailman/listinfo/openimscore-users>> wrote: > Hi, > I've downloaded this image of OpenIMSCore for VMware > http://www.digilo.com/openims/files/OpenIMS.2008-03-30.r545.rar > I've installed and runned it. > Now I want install on it a Presence Server so I've downloaded the > packages of the OpenSER 1.2.0 version 1.20. > Now, how can I install it onto che VMware image? > > Rob > > _______________________________________________ > OpenIMSCore-Users mailing list > OpenIMSCore-Users at lists.berlios.de<https://lists.berlios.de/mailman/listinfo/openimscore-users> > https://lists.berlios.de/mailman/listinfo/openimscore-users > -- Vladimir Romanov

[OpenSER-Users] problem in audio when using media proxy
by Krunal Patel 20 May '08

20 May '08

Hi, We are using openser with media proxy and radiator. We're having audio problems when we send calls to mediatrix gateway for termination. Internal calls work fine. We hear audio both side and we can see the session and bytes transfer properly in media proxy monitoring webpage. When we send calls to mediatrix gateway for termination, calls connect properly but we don't hear audio. We see inactive session in mediaproxy status page with no bytes transferring. One doubt I have is it is not entering reply route when it receives replies like 183, 180, etc. Has anyone encountered similar issue? How can we fix it? Thanks in advance! -- regards, Krunal Patel

[Serusers] Release schedule for 2.0?
by Marcus Better 18 May '08

18 May '08

Hi, I'm working on packaging ser for Debian. We currently ship 0.9.7, but have also packaged a 2.0 snapshot which seems to be working well. We now need to decide which version to ship in the upcoming "lenny" release of Debian. Do you have any information that you can share about the release plans for SER 2.0? This would help us a lot in making this decision. Thanks, Marcus
