TLS not enough memory issue with git master
by Anthony Messina 25 Nov '15

25 Nov '15

I have noticed the following issue which began with builds somewhere between git master commits bff0a08 and 6173ef7. I did not see this issue with my previous builds and haven't been able to pin down the problem, which is why I haven't formally filed a bug. Any help or guidance is appreciated, because this has crippled my use of Kamailio. Only a restart enables it to work again until the issue recurs. ERROR: tls [tls_server.c:189]: tls_complete_init(): tls: ssl bug #1491 workaround: not enough memory for safe operation: 8870536 ERROR: <core> [tcp_read.c:1303]: tcp_read_req(): ERROR: tcp_read_req: error reading I currently build against and run openssl-1.0.1k-12.fc22.x86_64. I have a very small operation and the only change on the operational side is that all 5 of my mobile UACs (yes, that's all) have switched from CSipSimple/Android to Zoiper/Android, which doesn't yet have support for client-side certificates so verify_certificate and require_certificate are off for both the server and client config. The server is started with: /usr/sbin/kamailio -P /run/kamailio/kamailio.pid -m 64 -M 8 I have tried modifying the shared mem to 128 but the issue still occurs. Even right now, I am seeing the error when only one UAC has established a TLS connection: # kamcmd tls.list { id: 572 timeout: 3475 src_ip: 10.77.79.156 src_port: 58688 dst_ip: 10.77.79.3 dst_port: 5061 cipher: ECDHE-RSA-RC4-SHA SSLv3 Kx=ECDH Au=RSA Enc=RC4(128) Mac=SHA1 ct_wq_size: 0 enc_rd_buf: 0 flags: 2 state: established } # kamailio.cfg enable_tls=yes loadmodule "tls.so" modparam("tls", "connection_timeout", 60) #modparam("tls", "tls_log", 1) #modparam("tls", "tls_debug", 1) #modparam("tls", "low_mem_threshold1", -1) #modparam("tls", "low_mem_threshold2", 0) modparam("tls", "session_cache", 1) # tls.cfg [server:default] method = TLSv1+ verify_certificate = no require_certificate = no private_key = /etc/kamailio/example.org.key.pem certificate = /etc/kamailio/example.org.crt.pem server_name = example.org cipher_list = ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA- AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-RC4-SHA:ECDHE-RSA-AES256- SHA:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-GCM- SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:RC4- SHA:AES256-GCM-SHA384:AES256-SHA256:CAMELLIA256-SHA:ECDHE-RSA-AES128- SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:CAMELLIA128- SHA:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK [client:default] method = TLSv1+ verify_certificate = no require_certificate = no private_key = /etc/kamailio/example.org.key.pem certificate = /etc/kamailio/example.org.crt.pem cipher_list = ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA- AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-RC4-SHA:ECDHE-RSA-AES256- SHA:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-GCM- SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:RC4- SHA:AES256-GCM-SHA384:AES256-SHA256:CAMELLIA256-SHA:ECDHE-RSA-AES128- SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:CAMELLIA128- SHA:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK Thanks. -Anthony -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

Kamailio/RTPProxy incorrect port 0
by Igor Potjevlesch 25 Nov '15

25 Nov '15

Hello, I can't figure out why Kamailio reports hundreds of calls with the following error: "/usr/local/sbin/kamailio[2997]: ERROR: rtpproxy [rtpproxy.c:2727]: force_rtp_proxy(): incorrect port 0 in reply from rtp proxy" It seems that each time this error occurs, we got a one-way audio call. I already check and increase the limit for opening files that the process can open with ulimit -n 500000. But, anyway, if I look to /proc/$PID/fd, I never see more than 1000 files open. I also check the socket with netstat: same; I can see the error while there's only less than 800 sockets open. Is someone know what can be the trigger of this? Regards, Igor.

Kamailio:Contact validation during INVITE
by Prashant Desai 25 Nov '15

25 Nov '15

Hi, We observe that the following kamailio API is trying to find out user registration by comparing source IP and port with stored contact, if it fails, then it compares based on incoming SIP msg contact uri. is_registered(struct sip_msg* _m, udomain_t* _d){ getContactP(_m,_d); } pcontact_t * getContactP(struct sip_msg* _m, udomain_t* _d) {); //Getting pcontact from source IP and port if (ul.get_pcontact_by_src(_d, &received_host, _m->rcv.src_port, _m->rcv.proto, &c) == 1) { LM_DBG("No entry in usrloc for %.*s:%i (Proto %i) found!\n", received_host.len, received_host.s, _m->rcv.src_port, _m->rcv.proto); } if (c == NULL) { //Getting pcontact from contact uri. if (ul.get_pcontact(_d, &ct->uri, &c) == 0) { } } We have use case where INVITE message is from same source IP and port but having unregistered contact.With this scenario,is_registered() will return success. We would like to know reason behind comparing the source IP and port to fetch the pcontact? Regards, Prashant

Grab users password from WWW-Auth header
by Alexandru Covalschi 24 Nov '15

24 Nov '15

Hello! My problem is I need to do users authentication through API. So I need to replace if (!www_authenticate("$td", "subscriber")) { www_challenge("$td", "1"); } With if (!my_auth_script()) { www_challenge("$td", "1"); } The main problem is - how can I grab or compare users password? I know nonce, which I understand is MD5 salt. Can I, for example, grab users password from API, then grab the MD5 string and the nonce user sent me, calculate MD5 on base of API password and nonce - and then compare MD5 strings sent by user and calculated? -- Alexandru Covalschi ABRISS-Solutions VoIP engineer and system administrator phone: +37367398493 web: http://abs-telecom.com/

Issue with SNMPstats
by Igor Potjevlesch 24 Nov '15

24 Nov '15

Hello, I have configured the SNMPstats module fine in my machine because I get the SNMP information with the new KAMAILIO MIBS but I don't understand why the value of kamailio dialogs is always 0: KAMAILIO-MIB::kamailioCurNumDialogs.0 = Gauge32: 0 KAMAILIO-MIB::kamailioCurNumDialogsInProgress.0 = Gauge32: 0 KAMAILIO-MIB::kamailioCurNumDialogsInSetup.0 = Gauge32: 0 KAMAILIO-MIB::kamailioTotalNumFailedDialogSetups.0 = Counter32: 0 However I can see the transactions: KAMAILIO-SIP-COMMON-MIB::kamailioSIPSummaryTotalTransactions.0 = Counter32: 54797 Should I configure an specific parametr of the SNMPstats module?

MESSAGE is not successfull in Kamailio IMS
by Thierry Luo 24 Nov '15

24 Nov '15

Hi All, I installed kamailio on Ubuntu as IMS pCSCF/iCSCF/sCSCF. REGISTER is fine, but when I tried to send a MESSAGE (SMS) from one user to another, it was always not successful. I captured IP packets on the server, and it seemed that the error was caused on pCSCF. User1 and User2 are both behind their NAT network. Suppose User1's private IP is Private_IP1, and User1's public IP (on router) is Public_IP1, and User2's private and public IPs are Private_IP2 and Public_IP2: User1 pCSCF iCSCF sCSCF user2 MESSAGE ----------------> MESSAGE ---------------------> MESSAGE -------------------> MESSAGE <----------------------------------------------------- MESSAGE ---------------------------------------------------------------------------- ----> Unfortunately, from the captured data on the server, in the last step, the MESSAGE was sent to the Private_IP2 of User2. It should be sent to the Public_IP2. Of course, the datagram with the destination of Private_IP2 cannot reach User2 successfully. Please help analyze why the pCSCF sent the MESSAGE packet to User2's private IP instead of public IP. The configuration file was attached for reference. BR. Thierry Luo

Simple User Agent change
by Steven Maddox 24 Nov '15

24 Nov '15

Hi, Sorry to ask something probably very simple but I'm difficulty finding the right kinds of resources to learn from which are succinct enough to not overload my head. We have a PBX which we don't control (and hate) which expects only certain makes/models phones to register (it checks for user agents). I have a phone which unfortunately doesn't support tweaking its user agent, so I'd like to pass it through an extremely SIP proxy to have it's user agent tweaked and all other data to/from the PBX transparently let through. I've managed to knock up something (that isn't a proxy) using Asterisk where I made a trunk and a peer... but obviously since this isn't a proxy... things like BLF and transferring calls will never work. If anyone can point me in the direction of a really simple set up to achieve this, please let me know :) -- Steven Maddox
