[Serusers] Help cant connect using natconfig
by Kirk McCalla 25 Jun '07

25 Jun '07

Hello all I have set up ser and I am able to use the sample config to get ser running within my NAT. Now I am trying to get external users to connect to my ser which is behind a nat device. Whenever I use the sample config I can make calls inside my netkwork. whenever I use the nat config that I have below. I cannot even get my local devices to speak to each other. Can someone help here. Whenever I start ser with this config this is what ther system does. ser dead but subsys locked <serusers(a)lists.iptel.org> This is the config that I am using # ----------- global configuration parameters ------------------------ debug=3 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode fork=no log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/textops.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_db.so" # !!

[Serusers] Odd error message....
by SIP 25 Jun '07

25 Jun '07

We've never seen this one come through before, so I'm thinking it's in some way related to the cortelco US that's being used.

Content-Length: 0. I'm really not sure which part of the URI is too short (or, to be honest, why SER spits out that message). Clearly '2.0' is not a valid URI... but I'm not entirely sure where it's getting that as the URI. Ideas? We're running 0.9.6. N.

[OpenSER-Users] RE: [Users] out of memory - please help
by Papadopoulos Georgios 25 Jun '07

25 Jun '07

Hi Bogdan, The server has been running for about 18 hours without any "out of memory" messages. Usually these appeared after a few hours. I think it is fixed, but I will keep you posted if it reappears. Thanks a lot! I guess the same fix needs to go in subst_uri() and maybe also add a check if(result->s!=0) ? Why did this only appear on the first receiver child? I would expect that all children receive an equal amount of traffic so they should all run out of memory more or less at the same time. Except if when a message is received, Openser finds the first available child and does this by trying child 1,2,3... Is this the case? Last (related?) question: There is a thread that the first receiver child starts, what is its purpose?

[OpenSER-Users] Help with subst()...
by Sajith T S 25 Jun '07

25 Jun '07

Hi, This looks simple, but I just can't wrap my (feeble) brain around it: Can anyone give a subst() regexp and replacement string to snip out "+" characters in the From header field's display name as well as user part of the URI? (There's a PSTN gateway that sends in caller's number with a "+" prefix and our users do not like it since they can't call back without manually editing out the "+"...) Thanks, Sajith.

[OpenSER-Users] User-Agent
by Christian Heidinger 24 Jun '07

24 Jun '07

Is it possible to modify the User-Agent/Server [Server: OpenSER (1.2.1-notls(x86_64/linux)).] field that OpenSER sends out? We use a variety of open source projects in production and prefer to sheild their true identities for security reasons (ie. preventing us from becoming the next victim of the newest exploit).
