hello Henning,
i would like to thank you very much. you save alot of work because i decided
to change my database from LDAP to MySQL. just to make it clear to anyone
who may face this problem.
the solution to keep you passwords hashed in the LDAP server is to save it
as HA1 = MD5(username:realm:password). after you build the HA1 save as clear
in the LDAP server (i am using openLADP). if you save it as MD5 you will
retrieve it as {MD5} blablabla which may cause a problem. so hash it then
save it as clear.
thanks for every one helps me in this issue
regards,
Ahmed Huraimel ALALI

Hi I?aki,
I had the same issue with a Nortel CS1k switch, the easiest way to check
this
problem is to use the Wireshark feature "Display raw text for SIP message"
which can be enabled under preferences / protocols / SIP
regards,
Andreas

Hello Inaki,
Perform a raw capture using tcpdump and open the file with wireshark.
Check the lower window in wireshark where you have the message
displayed in hex format.
There you will be able to spot '\n' and '\r'. To find the hex codes,
perform a 'man ascii' on your linux box.
Regards,
Ovidiu Sas

Thanks a lot.

Hi,
I have registered an UA 12345 , which is public.
In location table, I found NULL value for received.
I dial any UA , irrespective to their NAT status.
Call has been established but can't get audio both side.
It does not use mediaproxy for audio signaling.
How to resolve this problem?
Do a full sip flow capture and analyze trhe address and port of media in
SDP
of INVITE and 200 OK.

i am investigating the authentication on openSER.
I search for a proper
explanations but unfortunately i did not find how it is exactly done so i
did some experiments. i assumed that the response is generated as the
following: note that i set the username and password with the same string
"alali"
Response = MD5( username + MD5(password) + realm + nonce)
[..]
could anyone tell me how exactly the authentication is done in openSER?
is
the response generated is like the one i assumed?
what + means in the
response? does is mean concatenation or exoring?
Hi Ahmed,
the authentification in OpenSER/ SIP is based on HTTP auth. You find a
detailed explanation for the construction of the response for example at:
http://en.wikipedia.org/wiki/Digest_access_authentication , some further
informations at: http://www.voip-info.org/wiki/view/SIP+Authentication
For the exact logic inside OpenSER just take a look at the auth module
source
code, it should be not that hard to understand. ;-)
Cheers,
Henning
