[SR-Users] strange behavior when trying to reach PSTN gateway via TCP
Hi List! I'm running Kamailio for about 1 year without any serious problems. When it works with UDP only, it runs perfectly well for us. Without any major issues. But now we have a customer who wants to connect Lync to our network. Unfortunately, Lync does not support UDP for SIP signalling, so we tried to teach kamailio to send SIP messages via TCP. And getting strange error: 10(36629) DEBUG: tm [t_reply.c:659]: DEBUG: reply sent out. buf=0x832c7ac: SIP/2.0 100 trying -..., shmem=0x28d97c7c: SIP/2.0 100 trying - 10(36629) DEBUG: tm [t_reply.c:669]: DEBUG: _reply_light: finished 10(36629) DEBUG: core [forward.c:213]: DEBUG: get_out_socket: socket determined: 0x833ddc0 10(36629) DEBUG: core [msg_translator.c:457]: clen_builder: content-length: 553 (553) 10(36629) DEBUG: core [msg_translator.c:204]: check_via_address(10.200.245.200, 10.200.245.200, 0) 10(36629) DEBUG: core [tcp_main.c:1824]: tcp_send: no open tcp connection found, opening new one 10(36629) DEBUG: core [ip_addr.c:247]: tcpconn_new: new tcp connection: 10.198.3.100 10(36629) DEBUG: core [tcp_main.c:1081]: tcpconn_new: on port 5060, type 2 10(36629) DEBUG: core [tcp_main.c:1382]: tcpconn_add: hashes: 0:0:0, 1 10(36629) ERROR: core [tcp_main.c:2748]: connect 10.198.3.100:5060 failed Socket is not connected 10(36629) ERROR: core [tcp_main.c:2754]: 10.198.3.100:5060: connect send for 0x28d988ac failed: Socket is not connected (57) 10(36629) DEBUG: core [tcp_main.c:2955]: tcpconn_chld_put: destroying connection 0x28d988ac (1, -1) flags 0060 10(36629) ERROR: tm [../../forward.h:170]: msg_send: ERROR: tcp_send failed We tested two different variants: one when defined Lync in dr_gateways table as 10.198.3.100:5068;transport=tcp And then, tried global options udp_mtu=1300 udp_mtu_try_proto=TCP As soon as these options were enabled, all other gateways became unreachable with the same error as above.

Can you estimate the number of writes and how often they would be on a daily basis? There might be other solutions to look at, if writes are very often. i was thinking that perhaps mtree would be used to store numbers that are ported to other operators instead of the current carrier route pdb server, where the whole mmap file needs to be reloaded. in that application i would imagine a few hundred updates per hour, but many of them would only affect the value associated with the node, not the structure of the three. -- juha ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

Re: [SR-Users] tls-modules in 3.2.0
Klaus, Daniel, Thanks for responding. I am trying to understand what went wrong during the install. I Installed Kamailio 3.2.0 From GIT and followed the instructions in the wiki. According to the wiki Kamailio modules are installed in: /usr/local/lib/kamailio/modules/ and /usr/local/lib/kamailio/modules_k/. Then I wanted to test tls and installed kamailio-tls-modules. I added deb http://deb.kamailio.org/kamailio32 squeeze main and deb-src http://deb.kamailio.org/kamailio32 squeeze main to /etc/apt/sources.list, then run apt-get install kamailio-tls-modules. I guess maybe what happened is that all the Debian packages got installed again in /usr/lib/kamailio/. In the config file I changed the mpath from=/usr/local/lib/kamailio/modules_k/:/usr/local/lib/kamailio/modules/ to /usr/lib/kamailio/modules_k/:/usr/lib/kamailio/modules/ and everything is working now. Is this the right way to install the kamailio-tls-module? How do I clean this since I have all the modules installed again in usr/lib/kamailio/modules/. Also the config file is present both in /etc/kamailio and /usr/local/etc/kamailio/. Which one I should keep editing? I thought using the GIT install method is better cause it's easy to pull changes in the future. Thanks for your inputs and all the work you're doing.

Re: [SR-Users] mtree on db Berkeley DB?
Hello coming back to the topic related to mtree, to be able to set values via mi/rpc -- it won't be that difficult to add such functionality. Usually with a tree is mainly reading, due to fast matching on tree indexing. The question is how many times/often do you need to change values and how many of them at the same time (more or less). I was also thinking about that: our application works in such a way that the full tree is recalculated every 15 minutes. Currently we have aound 60 branches with 15 entries each. I assume many times the changes will be somewhere down the tree, since the first part of the number is usually the same (e.g., country code and operator prefix). To update the tree at runtime, while there are reads on it, there must be used a lock to be safe an consistent. If you do lot of writes and very often, then you keep the tree structure locked a lot, slowing the search. That's the case, tname is rarely updated, it's tvalue the column that we normally update. Can you estimate the number of writes and how often they would be on a daily basis? There might be other solutions to look at, if writes are very often. From the numbers above, let's say that we need to update around 8M records every 15 minutes (we expect this number will keep steadily increasing...) As a side note, I've looked at how to implement the mt_match equivalent in redis and it does't look that hard using kamailio s.prefixed transformation (as you suggested) and redis sorted sets. I'll need to make more tests to check the performance, I'll share the results. Thanks!

Re: [SR-Users] sqlops crash when connection does not exist
Hello, looks like the issue is in the way shut down is done. In this specific case, sqlops does not initialize properly due to misspell, causing kamailio to shut down -- otherwise there is no issue with sqlops itself. At shutdown, the destroy function of each module is called, then the module structure is freed. Looks like mysql module is destroyed first, then htable module is destroyed, which needs to connect to sync back the content in memory to db tables, but the mod exports structure for mysql is invalid now causing a fault access. I will make a patch for it.

If you do lot of writes and very often, then you keep the tree structure locked a lot, slowing the search. daniel, could the lock be from the node that requires modification downwards, which would leave all other branches unlocked? for large trees it would be not possible to have a lock for each node, there will be too many and different operating systems have limits. On a hash table there is a lock per slot, no matter how many items are in the table. In a tree is hard to define a set of locks and just going with one per node is not that feasible. For eaxample one record with prefix 0123456789 creates 10 nodes, then some nodes are reused, but still there are a greater or equal number of nodes than the number of records loaded. Can you estimate the number of writes and how often they would be on a daily basis? There might be other solutions to look at, if writes are very often. i was thinking that perhaps mtree would be used to store numbers that are ported to other operators instead of the current carrier route pdb server, where the whole mmap file needs to be reloaded. in that application i would imagine a few hundred updates per hour, but many of them would only affect the value associated with the node, not the structure of the three. Adding a record (i.e., prefix/value) in a tree should be fast if building the missing sub-tree part of it and then just linking it to the main tree. Removing might need more time, a solution for it can be just setting the value to NULL and keep the tree structure..

Hello, On 11/15/11 10:09 PM, Javier Gallart wrote: Hello coming back to the topic related to mtree, to be able to set values via mi/rpc -- it won't be that difficult to add such functionality. Usually with a tree is mainly reading, due to fast matching on tree indexing. The question is how many times/often do you need to change values and how many of them at the same time (more or less). I was also thinking about that: our application works in such a way that the full tree is recalculated every 15 minutes. Currently we have aound 60 branches with 15 entries each. I assume many times the changes will be somewhere down the tree, since the first part of the number is usually the same (e.g., country code and operator prefix). To update the tree at runtime, while there are reads on it, there must be used a lock to be safe an consistent. If you do lot of writes and very often, then you keep the tree structure locked a lot, slowing the search. That's the case, tname is rarely updated, it's tvalue the column that we normally update. I guess you meant actually tprefix is not updated -- tname is table name, tprefix is the prefix used to build the tree. What would be the percentage of tvalue updates, do you have add/remove of tprefix-es? Can you estimate the number of writes and how often they would be on a daily basis? There might be other solutions to look at, if writes are very often. From the numbers above, let's say that we need to update around 8M records every 15 minutes (we expect this number will keep steadily increasing...) But not all of them change the value, right? As a side note, I've looked at how to implement the mt_match equivalent in redis and it does't look that hard using kamailio s.prefixed transformation (as you suggested) and redis sorted sets. I'll need to make more tests to check the performance, I'll share the results. I have used this solution with mysql (using a table structure in memory of mysql server), since the changes could have been done in mysql in normal way, in one update query, which is a sync operation. Does redis do any caching or is using always the disk file db? Cheers, Daniel Thanks!

Re: [SR-Users] strange behavior when trying to reach PSTN gateway via TCP
Hello, you haven't disabled tcp support, right? Can you do 'kamctl ps' and see if you have tcp workers? I see the error is related to 10.198.3.100:5060 : 10(36629) ERROR:core [tcp_main.c:2748]: connect 10.198.3.100:5060 failed Socket is not connected What is listening on this ip and port? In drouting table you have 10.198.3.100:5068;transport=tcp -- a different port. Then, do you need to enable and play with mtu params? This is for auto-switching from UDP to TCP when size of SIP message exceeds udp_mtu value in bytes, done by SIP server, but if the other party is not listening on tcp, then it won't work (reason is disabled by default) -- note that this switching will be done for all sip messages.
