fail2ban complains about Kamailio syslog messages
by Juha Heinanen 12 Nov '24

12 Nov '24

When Kamailio message parser produces this kind of syslog message: 024-11-11T21:16:40.757364+02:00 box /usr/bin/sip-proxy[181398]: ERROR: <core> [core/parser/msg_parser.c:791]: parse_msg(): ERROR: parse_msg: message=<#026#003#001#006\340#001> fail2ban complains: Consider setting logencoding to appropriate encoding for this jail.

Last line of onreply_route (drops reply)
by James Browne 11 Nov '24

11 Nov '24

Hi all I noticed, in my config, that if the last line of the reply_route is a function that does not succeed, then the SIP response is not relayed and kamailio throws an error. I've searched documentation to indicate why this might be, but I can't find anything, so this looks to me like a bug. I use 5.8.1 for testing. Here's a sample config that shows what goes wrong. #################### #!KAMAILIO listen=udp:203.0.113.57:5060 debug=1 loadmodule "textops" request_route{exit;} reply_route{remove_hf_re("^X-Custom");} #################### Here's a sample SIP message that works. When I send this to udp:203.0.113.57:5060, kamailio relays it. #################### SIP/2.0 200 Testing Via: SIP/2.0/UDP 203.0.113.57:5060;branch=z9hG4bK-d8754z Via: SIP/2.0/UDP 198.18.0.157:5060;branch=z9hG4bK-d8754z T: <sip:c@s>;tag=676fbf45 F: <sip:c@s>;tag=676fbf45 X-Custom: lkjdfl i: testing-XXX CSeq: 1 INFO l: 0 #################### If I then remove the X-Custom header field from the SIP reply and try again, the message does not get relayed and I see this in the log. 5(1356) WARNING: <core> [core/receive.c:605]: receive_msg(): error while trying onreply script If I put a log command after the remove_hf_re(), then the message gets relayed. It looks like the reply_route always fails if the last function is not successful. Is this normal or is it a bug? James

Question regarding error message "failed to add new socket to the fd list"
by Floimair Florian 11 Nov '24

11 Nov '24

Hi! We have recently had issues with one of our Production Kamailios. When those happened, the log was filled with the following message: CRITICAL: <core> [core/tcp_main.c:4528]: handle_new_connect(): failed to add new socket to the fd list Now I wonder what the best approach is to prevent this. We are using TCP/TLS only and I think this might be related to the file ulimit, but I am not sure about that. Shared memory is set to 512MB Can you give me a hint on what to look for? Thank you very much! P.S.: Sorry, I accidentally replied to a previous post of a different topic before which is totally unrelated (I think I should stop working for today 😉) FLORIAN FLOIMAIR Software Development - Symphony Cloud Services Commend International GmbH Saalachstrasse 51 5020 Salzburg, Austria [signature_2072127332] commend.com LG Salzburg / FN 178618z

apt-key deprecation
by tom＠tomlynn.com 11 Nov '24

11 Nov '24

When I look at the debian repositories maintained by the project, there are instructions to import the public key of the repository for apt using this command: wget -O http://deb.kamailio.org/kamailiodebkey.gpg | sudo apt-key add - which results in: Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). gpg: no valid OpenPGP data found. Is there an alternate method that can be posted in the repository that will get better results? Thank you, TL

[db_unixodbc] how to specify the database with unixodbc？
by 17603019528＠163.com 08 Nov '24

Hi Dear Community, I want to use db_unixodbc to connect to the dm8 database. Although I use Opensips, I found that this module db_unixodbc, Kamailio and Opensips are the same.

Draining TCP/TLS SIP sessions from Kamailio and media sessions from RTPEngine
by Evgenii Buchnev 07 Nov '24

07 Nov '24

Hi Dear Community, Would appreciate your input into where to look further to explore my options and would be good to learn your experience with the following. There are many active-active kamailio nodes behind tcp load balancer. On the same VM with each Kamailio there is an instance of RTPEngine to manage Media/Transcoding/Etc for that Kamailio. This scales UP easily - new nodes just added behind tcp load balancer. To be able to scale down and/or update node configuration - I'd like to be able to drain sessions/calls properly and pass any active calls from current Kamailio and RTPEngine to other nodes. DMQ is not yet in place, although it's planned. What would be proper ways of migrating RTP sessions to other RTPEngines? Caveats? Also wonder how properly a tcp/tls based SIP session can be passed to another Kamailio? Thank you in advance for your input. Evgenii Buchnev

Roadmap to v6.0.0 - the next major release
by Daniel-Constantin Mierla 07 Nov '24

07 Nov '24

Hello, about 8 months since the last major release v5.8.x, therefore it is the time to plan a bit the next steps for getting v6.0.0 out. The Kamailio Developers Meeting is schedule in Dusseldorf, Germany during November 19-20, 2024, where we expect to push out a consistent number of updates. Then maybe we can wait for another 2 weeks or so to settle down/finish those updates. After that, if no other new features are planned by developers in short term, we can enter the testing phase, so the new major version can be released during the second part of January 2025 or first part of February 2025. Therefore, if you have new features under development that might require more than 1-1.5 months from now, and you want to get them in v6.0.0, let us know to plan properly. Other time lines suggestions to get to v6.0.0 are also welcome!

SNMP setup
by Sergio Charrua 05 Nov '24

05 Nov '24

Hi all! I am having difficulties setting up SNMP, and mostly to figure out if what I have setup is correctly configured. This is what I have on Kamailio (5.8.2), which is set as stateless and as a redirect server (simply put, it receives INVITE from SBC, gets a route from routing services, modifies Contact header, and replies to SBC with 300 Multi Choice with new contact header): loadmodule "db_mysql.so" loadmodule "db_cluster.so" loadmodule "http_client.so" loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "sl.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "textops.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "jansson.so" loadmodule "snmpstats.so" loadmodule "file_out.so" loadmodule "ctl.so" loadmodule "permissions.so" loadmodule "xhttp.so" loadmodule "xhttp_rpc.so" # ---- SNMP Stats params ---- modparam("snmpstats", "sipEntityType", "proxyServer") modparam("snmpstats", "sipEntityType", "redirectServer") modparam("snmpstats", "sipEntityType", "other") modparam("snmpstats", "snmpgetPath", "/usr/bin/") modparam("snmpstats", "MsgQueueMinorThreshold", 1) modparam("snmpstats", "MsgQueueMajorThreshold", 1) modparam("snmpstats", "dlg_minor_threshold", 1) modparam("snmpstats", "dlg_major_threshold", 1) modparam("snmpstats", "snmpCommunity", "kamailio") I have set the *_minor_threshold values to bear minimum. Should I add anything else? The logs show the following messages: DEBUG: <core> [core/mem/q_malloc.c:402]: qm_malloc(): qm_malloc(0x7f03af1ff010, 60) called from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) DEBUG: <core> [core/mem/q_malloc.c:449]: qm_malloc(): qm_malloc(0x7f03af1ff010, 64) returns address 0x7f03af3bcc50 frag. 0x7f03af3bcc10 (size=64) on 1 -th hit DEBUG: <core> [core/mem/q_malloc.c:402]: qm_malloc(): qm_malloc(0x7f03af1ff010, 20) called from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) DEBUG: <core> [core/mem/q_malloc.c:449]: qm_malloc(): qm_malloc(0x7f03af1ff010, 32) returns address 0x7f03af3bcd00 frag. 0x7f03af3bccc0 (size=32) on 1 -th hit DEBUG: <core> [core/mem/q_malloc.c:515]: qm_free(): qm_free(0x7f03af1ff010, 0x7f03af3bcc50), called from snmpstats: snmp_statistics.c: get_total_bytes_waiting(464) DEBUG: <core> [core/mem/q_malloc.c:562]: qm_free(): freeing frag. 0x7f03af3bcc10 alloc'ed from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) DEBUG: <core> [core/mem/q_malloc.c:515]: qm_free(): qm_free(0x7f03af1ff010, 0x7f03af3bcd00), called from snmpstats: snmp_statistics.c: get_total_bytes_waiting(471) DEBUG: <core> [core/mem/q_malloc.c:562]: qm_free(): freeing frag. 0x7f03af3bccc0 alloc'ed from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) DEBUG: <core> [core/mem/q_malloc.c:402]: qm_malloc(): qm_malloc(0x7f03af1ff010, 60) called from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) DEBUG: <core> [core/mem/q_malloc.c:449]: qm_malloc(): qm_malloc(0x7f03af1ff010, 64) returns address 0x7f03af3bcc50 frag. 0x7f03af3bcc10 (size=64) on 1 -th hit DEBUG: <core> [core/mem/q_malloc.c:402]: qm_malloc(): qm_malloc(0x7f03af1ff010, 20) called from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) DEBUG: <core> [core/mem/q_malloc.c:449]: qm_malloc(): qm_malloc(0x7f03af1ff010, 32) returns address 0x7f03af3bcd00 frag. 0x7f03af3bccc0 (size=32) on 1 -th hit DEBUG: <core> [core/mem/q_malloc.c:515]: qm_free(): qm_free(0x7f03af1ff010, 0x7f03af3bcc50), called from snmpstats: snmp_statistics.c: get_total_bytes_waiting(464) DEBUG: <core> [core/mem/q_malloc.c:562]: qm_free(): freeing frag. 0x7f03af3bcc10 alloc'ed from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) DEBUG: <core> [core/mem/q_malloc.c:515]: qm_free(): qm_free(0x7f03af1ff010, 0x7f03af3bcd00), called from snmpstats: snmp_statistics.c: get_total_bytes_waiting(471) DEBUG: <core> [core/mem/q_malloc.c:562]: qm_free(): freeing frag. 0x7f03af3bccc0 alloc'ed from snmpstats: snmp_statistics.c: get_socket_list_from_proto_and_family(185) INFO: snmpstats [utilities.c:116]: get_statistic(): failed to retrieve statistics for active_dialogs INFO: snmpstats [utilities.c:116]: get_statistic(): failed to retrieve statistics for active_dialogs The SNMP daemon is set as follows: - /etc/snmp]$ cat snmptrapd.conf # Example configuration file for snmptrapd # # No traps are handled by default, you must edit this file! # # authCommunity log,execute,net public # traphandle SNMPv2-MIB::coldStart /usr/bin/bin/my_great_script cold and on /etc/snmp/snmpd.conf: ############################################################################### # Further Information # # See the snmpd.conf manual page, and the output of "snmpd -H". agentaddress udp:161 rocommunity kamailio master agentx agentXSocket tcp:localhost:705 trap2sink 10.X.Y.Z netcool 162 When running tcpdump and listening on port 162, no traffic is captured....it seems to me that Kamailio is not sending anything to SNMP Any clue, anyone?
