[OpenSIPS-Users] REG::Zero Window in opensips 1.11.5

[Ravitez Ravi]

Hi All,

Good Day,

I’m using opensips V1.11.5-TLS and facing a problem with
Zero Window.

Here’s the scenario :

NOTIFY

Opensips client ---à App server

200 OK

Opensips  ß App Server



Now lets assume this

NOTIFY

Opensips client ---à App server

NOTIFY

Opensips client ---à App server

NOTIFY

Opensips client ---à App server

NOTIFY

Opensips client ---à App server

NOTIFY

Opensips client ---à App server

NOTIFY

Opensips client ---à App server

NOTIFY

Opensips client ---à App server

200 OK|200 ok | 200 ok | 200 ok

Opensips  ß App Server



Assuming the size of response if 5000 bytes.

tcp_main detects data in the buffer and passes on to the child process to
read the data from the buffer,

child(buffer size 65535 ) now reads the data from the socket

tcp_read_req()

-  tcp_read_headers()

-  Loops until all the sip messages are extracted and
forwarded/processed

-  Releases the connection to tcp_main



Tcp_main attaches  to IO



During the timer interval where  system reads the data from the socket and
process  the data there would be new data pipelined in the socket, this
gradually  results in Zero window L

Would like to know if there’s a way to process the next available data on
the socket once its been read.Thank you for your time J

[OpenSIPS-Users] Issues running opensips with load balancer.

[Ravitez Ravi]

Hi All,

I’m trying to run opensips with load balancer module but it fails to come
up. Below are details of what I have done and been trying. My questions are
in *bold italics and highlighted in yellow*. Request you to take a look and
help.



*Objective:* Install OpenSIPS 1.11.10 with TLS on RHEL 6.5 for load
balancing SIP traffic

*Procedure followed:*

1.   Download and install OpenSIPS1.11.10 on RHEL 6.5 with default
configuration:

a.   Downloaded
http://opensips.org/pub/opensips/1.11.10/opensips-1.11.10-tls.tar.gz

b.  Un-tar and un-zip the downloaded file

c.   Go to opensips-1.11.10-tls folder, ran make menuconfig, select Compile
And Install OpenSIPS and followed by Exit & Save All Changes

d.  Run opensips on command line, ensure the opensips process is
running using ‘ps -ef | grep opensips’ command and stop the process
using ‘killall
opensips’



2.   Get necessary dependencies straightened out for load balancer as
mentioned in section 1.4 in
http://www.opensips.org/html/docs/modules/1.11.x/load_balancer.html

a.   The section lists the following OpenSIPS modules: i) *Dialog* –
Dialog module, ii) *Dialog* – TM module, iii) *database* – one of the DB
modules.

b.  I did not see any specific dialog module either in Configure
Compile Flags or Configure Excluded Modules, however, I could see
/usr/local/lib64/opensips/modules/dialog.so and assumed this is the
intended module. *Not sure if it covers both Dialog and TM. Please clarify.*

c.   I selected db_mysql from Configure Excluded Modules and got a
message “You have enabled the 'db_mysql' module, so please install '
development libraries of mysql-client , typically libmysqlclient-dev'”
while saving. I could not find the RPM for RHEL. The closed I could
find is libmysqlclient16-devel-5.1.69-1.w6.x86_64.rpm
which fails to get installed. *Am I in right path here? Please advise.*

d.  I was following an example mentioned section 3.2 in
http://www.opensips.org/Documentation/Tutorials-LoadBalancing.

The section shows following modules to be loaded:

loadmodule "modules/maxfwd/maxfwd.so"

loadmodule "modules/sl/sl.so"

loadmodule "modules/db_mysql/db_mysql.so"

loadmodule "modules/tm/tm.so"

loadmodule "modules/xlog/xlog.so"

loadmodule "modules/uri/uri.so"

loadmodule "modules/rr/rr.so"

loadmodule "modules/dialog/dialog.so"

loadmodule "modules/mi_fifo/mi_fifo.so"

loadmodule "modules/mi_xmlrpc/mi_xmlrpc.so"

loadmodule "modules/signaling/signaling.so"

loadmodule "modules/textops/textops.so"

loadmodule "modules/load_balancer/load_balancer.so"

However, the sub-directories mentioned in above list is not seen on my file
system after OpenSIPS installation, yet I see some of the above list shared
libraries under /usr/local/lib64/opensips/modules. *Hope this is ok.*

e.  The defaults opensips.cfg provided includes most of the above
listed modules, but the below libraries were missing which are needed for
load balancer:

loadmodule "modules/dialog.so"

loadmodule "modules/textops.so"

loadmodule "modules/load_balancer/load_balancer.so"

loadmodule "modules/db_mysql/db_mysql.so"

loadmodule "modules/xlog/xlog.so"

loadmodule "modules/mi_xmlrpc/mi_xmlrpc.so

I was able to successfully start opensips after loading dialog.so and
textops.so, however, opensips refuses to start when I load
load_balancer.so with
following error:

Re: [OpenSIPS-Users] REG::Opensips V1.11.5 & V1.11.10 Duplicate TCP Conections

[Ravitez Ravi]

Hello Razvan,
Good Day,
Would like to bring up that if children(workes) try to
create TCP connections without a locking mechanism we may hit TCP
connection limit and  not process or handle valid requests

eg :
tcp_max_connections=10;
tcp_connection_lifetime=43200;
tcp_children=32

  Considering the above configuration with the existing
framework we can use up all 10 connections and then reject new connections.
  Please advise.Thank you :)


Regard,
Ravitez.D

Re: [OpenSIPS-Users] REG::Multiple TCP Connections to Same Destination.

[Ravitez Ravi]

Hello Bogdan,
  Good Day,
  Congestion happens on the receive Q of opensips(UAS -> opensips)
when UAS tries to send ~3000 messages in one second.
  and  i see multiple tcp_connections being created to the same
destination (SBC) but based on the logic only the recent or the last
connection is
  being used,when tcp_async is used i see readQ (USA->opensips) not
being read (still see n number of bytes).
  Thank you.

Regards,
Ravitez.D

Re: [OpenSIPS-Users] REG::Opensips V1.11.5 & V1.11.10 Duplicate TCP Conections

[Ravitez Ravi]

Hello Razvan,
   God Day,
   Thank you for the update,it seems that though we create
multiple TCP connections opensips uses only one tcp connection to send the
data out.
   should a child be locking the tcp connection mechanism?
while creating a new tcp connection as we will be overwriting the
tcpconn_aliases_has to the
   latest/recent fd.

 I believe here's the root cause :
- When a child tries to find a connection to the destination it
calls _tcpconn_find() (assuming we are using ip and not id) system
checks *tcpconn_aliases_hash
*for the connection info.
 * this map is maintained by the parent process and each child lock its
while reaing tcpconn_get().in order to simulate the scenario lets
assume a->parent->state is BAD this method*
*  will return null and so the child tries to create a new
connections,assuming there's a second child trying to find the same
connections and goes through the same process*

  - *Now each child thinks there's no connection to the destination and
calls tcpconn_connect() this will create a socket to the destination and
passes over the fd to the *
*main process to update the has map.*

  - *Not sure if tcp_connect() should have locking mechanism as in
tcpconn_get().*

   Thank you :)

[OpenSIPS-Users] REG::Opensips V1.11.5 & V1.11.10 Duplicate TCP Conections

[Ravitez Ravi]

Hi All,
Good Day,
I have been seeing opensips creating mutiple(duplicate) TCP
connections to the same destination if hit with heavy call load.

*What do i mean?*
opensips ip : 10.10.10.1
Destination  : 10.10.10.2
Tcp Children : 32

Ideally opensips will create only one tcp connections and reuses it,if
there's a heavy call load i see there are several tcp connections which are
created to the same destination.
I believe here's the root cause :
- When a child tries to find a connection to the destination it calls
_tcpconn_find() (assuming we are using ip and not id) system checks
tcpconn_aliases_hash for the connection info.
  this map is maintained by the parent process and each child lock its
while reaing tcpconn_get().in order to simulate the scenario lets assume a->
parent->state is BAD this method
  will return null and so the child tries to create a new
connections,assuming there's a second child trying to find the same
connections and goes through the same process

  - Now each child thinks there's no connection to the destination and
calls tcpconn_connect() this will create a socket to the destination and
passes over the fd to the
main process to update the has map.

  - Not sure if tcp_connect() should have locking mechanism as in
tcpconn_get().



Please correct me if my understanding is wrong,please share your thoughts.

[OpenSIPS-Users] REG::Multiple TCP Connections to Same Destination.

[Ravitez Ravi]

Hello,
   I have been using opensips 1.11.5 as a proxy between the application
server and clients,things were fine as each client had a dedicated tcp
connection to opensips.
   once i introduced SBC ,opensips has only one TCP connection to SBC
.would it be possible to create multiple TCP connections to the same
destination?.
eg :
 Each child having a TCP connection to the same destination.

 from what i understand is if a tcp connection exists to a destination
opensips passes on the fd to a requesting child to send data.
 please share your thoughts.

Hi All,
Good Day,
Here's the problem i'm facing and would be a great help if you
could comment.
Thank you.

is_myself() does not check for SIPS port if connection type is TLS
*Configuration :*
- Opensips V1.11.5 running in secure mode on port 5061
- Avaya trying to communicate with Opensips server.
- Opensips server ip 192.168.1.11
- Avaya ip : 192.168.1.20


*Steps :*
- Avaya sends INVITE to Opensips with route header
Route:

Hello All,
Good Day and a Happy New Year.
I have two instances of openSips(V1.11) executable running say
"opensips1" and "opensips2"
when i execute opensipsctl it always picks up data from
"opensips2" is there a way that we can
choose which executable to pick.Thank you for the help.

[OpenSIPS-Users] Opensips fails to ESTABLISH TLS for non-slandered Secure SIP port

[Ravitez Ravi]

*Hello All,*
OpenSIPS fails to establish TLS connection with far end which
is listening to non-standard secure SIP port (i.e., far end listening on
port other than 5061).

*Setup details:*
TLS client: OpenSIPS 1.11.5 running on RHEL 6.5
TLS client listen port: 5061
TLS client IP: 10.204.182.27
TLS server: Blink VOIP soft phone running on Windows 7 desktop
TLS server listen port: 5062
TLS server IP: 10.204.45.62

*Scenario:*
OpenSIPS is TLS client & Blink VOIP soft phone is TLS server.
OpenSIPS tries to initiate a TLS session & successfully establishes a TCP
connection:
• OpenSIPS/Client[49384] -> Blink/Server[5062] - TCP [SYN]
• Blink/Server[5062] -> OpenSIPS/Client[49384] – TCP [SYN, ACK]
• OpenSIPS/Client[49384] -> Blink/Server[5062] – TCP [ACK]
• OpenSIPS/Client[49384] -> Blink/Server[5062] – TCP [PSH, ACK]

*Expected to see OpenSIPS sending ‘Client Hello’ to Blink, however, I see
nothing here after. *

[OpenSIPS-Users] REG::Opensips 1.11.5 with dual client domain

[Ravitez Ravi]

Hello Everybody,
Unable to configure opensips with dual client domains,below
is the configuration and opesips logs
opensips.cfg
{
...
listen=tls:IP_2:port2
listen=tls:IP_3:port4
...
# set the TLS client domain AVP
tls_client_domain_avp = 400

# name based TLS client domains (for virtual SIPS hosting)
tls_client_domain["atlanta.com"] {
tls_certificate = "/certs/atlanta.com/cert.pem"
tls_private_key = "/certs/atlanta.com/privkey.pem"
tls_ca_list = "/certs/wellknownCAs"
tls_method=tlsv1
tls_verify_server = 1
}
tls_client_domain["biloxi.com"] {
tls_certificate = "/certs/biloxy.com/cert.pem"
tls_private_key = "/certs/biloxy.com/privkey.pem"
tls_ca_list = "/certs/wellknownCAs"
tls_method=tlsv1
tls_verify_server = 0
}

route{
...
# calls to other SIP domains
# set the proper SSL context (certificate) for local hosted domains
*avp_write("$fd","$avp(i:400)"); # does not exists in
1.11.5 can you please share the alternate function.!*
forward(); # uses NAPTR and SRV lookups
exit;
}


*Opensips Log :*
""no TLS client doman AVP set, looking for socket based TLS client domain""


I think internal_search_ID_avp in user_avp.c is failing.
Can some one please comment on how to get this working.
Thank you.

[OpenSIPS-Users] Fwd: REG::Multi Domain Handling in Opensips

[Ravitez Ravi]

Hello All,
 I'm developing a system which will be using opensips,one of the
requirement is that when the system acts as a client/server
 it should use a specific certificate for a similar bunch of
servers,eg one certificate for all local end points and other
 for all Trunks,it would be great if you could provide your
suggestions on how to achieve this

   opensips
HS Cert  Trunk Cert
||
Handset 1<---   | |--->Trunk 1
Handset 2<---| |---> Trunk 2
Handset 3<---| |---> Trunk 3


opesips.cfg

//Sample
tls_server_domain[Handset]
{
//use handset  certs
}

tls_server_domain[Trunk]
{
//Use trunk  certs
}

tls_client_domain[Handset]
{
//user handset certs
}

tls_client_domain[Trunk]
{
//use trunk certs
}


Thank you for the help.
