### Description DNS failover do not wok for localy generated transaction when script forcing socket or sets Via parameters with corex via_add_srvid/via_add_xavp_params, in log appear the errors: ``` Dec 24 13:30:17 sbc kamailio[9772]: 10(9800) DEBUG: <core> [core/parser/parse_uri.c:1306]: parse_uri(): bad uri, state 0 parsed: <<F3>gbf> (4) / <<F3>gbf#017^?> (38) Dec 24 13:30:17 sbc kamailio[9772]: 10(9800) ERROR: tm [ut.h:245]: uri2dst2(): bad_uri: [<F3>gbf#017^?] ``` #### Reproduction Config stripped for localize problem: ``` #!define IPADDR_THISNODE "192.168.122.130" #!subst "/IPADDR_THISNODE/192.168.122.130/" #!define MULTIDOMAIN 0 ####### Global Parameters ######### #!define WITH_DEBUG ### LOG Levels: 3=DBG, 2=INFO, 1=NOTICE, 0=WARN, -1=ERR #!ifdef WITH_DEBUG debug=4 log_stderror=yes #!else debug=2 log_stderror=no #!endif memdbg=5 memlog=5 log_facility=LOG_LOCAL0 log_prefix="{$mt $hdr(CSeq) $ci} " /* number of SIP routing processes */ children=8 server_id = 10 xavp_via_params = "via" /* uncomment the next line to disable TCP (default on) */ disable_tcp=yes /* uncomment the next line to disable the auto discovery of local aliases * based on reverse DNS on IPs (default on) */ # auto_aliases=no /* listen on local and anycast addresses */ listen=udp:IPADDR_THISNODE:5060 #### DNS settings use_dns_cache = on # Use KAMAILIO internal DNS cache use_dns_failover = on # Depends on KAMAILIO internal DNS cache #dns_srv_loadbalancing = on # #dns_try_naptr = on # dns_try_naptr = off # dns_retr_time=1 # Time in seconds before retrying a DNS request dns_retr_no=1 # Number of DNS retransmissions before giving up dns_try_ipv6=yes dns_use_search_list=no ####### Modules Section ######## /* set paths to location of modules */ loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "ctl.so" loadmodule "cfg_rpc.so" loadmodule "counters.so" loadmodule "dispatcher.so" # ----------------- setting module-specific parameters --------------- # ----- jsonrpcs params ----- modparam("jsonrpcs", "pretty_format", 1) /* set the path to RPC fifo control file */ # modparam("jsonrpcs", "fifo_name", "/run/kamailio/kamailio_rpc.fifo") /* set the path to RPC unix socket control file */ # modparam("jsonrpcs", "dgram_socket", "/run/kamailio/kamailio_rpc.sock") # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) # ----- tm params ----- modparam("tm", "fr_timer", 2000) #modparam("tm", "reparse_on_dns_failover", 0) # ----- dispatcher params ----- modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list") modparam("dispatcher", "ds_ping_interval", 10) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_probing_threshold", 2) modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "outbound_proxy", "sip:proxy") # ----- corex params ----- modparam("corex", "dns_cache", "type=A;name=proxy;addr=192.168.122.129;ttl=3600000;flags=2") modparam("corex", "dns_cache", "type=A;name=proxy;addr=192.168.122.131;ttl=3600000;flags=2") # ----- rr params ----- # set next param to 1 to add value to ;lr param (helps with some UAs) modparam("rr", "enable_full_lr", 0) # do not append from tag to the RR (no need for this script) modparam("rr", "append_fromtag", 0) onsend_route { xinfo(">> onsend_route snd_to=$sndto(ip)\n");

[kamailio/kamailio] register using uac module is getting send even if send_socket is not in this listening list of kamailio (#2624)
by Surendra Tiwari 31 Jan '22

31 Jan '22

### Description I am uac module with database. uacreg table have the send_socket column. i do have 2 kamailio server running. i want only kamailio-1 should send register to uacreg entries. for this i have used send_socket column with socket of kamailio-1. After this we can see both kamailio server sending registration and that's the problem.  ### Troubleshooting #### Reproduction loadmodule "uac.so" modparam("uac","auth_username_avp","$avp(auser)") modparam("uac","auth_password_avp","$avp(apass)") modparam("uac","auth_realm_avp","$avp(arealm)") modparam("uac", "reg_contact_addr", "EXTERNAL_IP:5060") modparam("uac", "reg_db_url", DBURL) and use send_socket into uacreg with kamailio-1 socket.  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.3.8 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 8.3.0 ``` * **Operating System**:  ``` root@ip-10-0-12-135:/etc/kamailio# uname -a Linux ip-10-0-12-135 5.3.0-1019-aws #21~18.04.1-Ubuntu SMP Mon May 11 12:33:03 UTC 2020 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] REGISTER with http_async_client (Issue #3009)
by cyril-rm 27 Jan '22

27 Jan '22

Hi there, I have a weird issue with kamailio (latest docker image kamailio-ci:5.5.2-alpine) and http_async_client. Before posting a lot of logs, let me describe what I want to achieve. I have a Kamailio and a SIP Phone. The SIP phone sends a REGISTER to kamailio, then in my routing block, I check if I have an Authorization header. Since I don't have an Authorization (first message), I use "www_challenge()". This replies to the SIP phone, and then the SIP phone sends a new REGISTER with the correct Authorization header. So far so good. Now, when I get the REGISTER with Authorization header, I want to ask an HTTP endpoint if this user is allowed to connect and check the password using http_async_query(). The problem is that when the transaction resumes, the tmx module is unhappy and throws this error : `30(36) CRITICAL: tmx [t_var.c:546]: pv_get_tm_reply_code(): no picked branch (-1) for a final response in MODE_ONFAILURE ` And a 500 error is sent back to the sip phone. The AUTH_REPLY route is still called and I can use the $http* values. it seems that my AUTH_REPLY route is called but considered as a "failure_route" `19(27) exec: *** cfgtrace:dbg_cfg_trace(): failure_route=[AUTH_REPLY] c=[/etc/kamailio/kamailio.cfg] l=665 a=16 n=if ` Do you see something that I am doing wrong or missing in my logic? Is pausing/resuming to use the async http client is allowed if I'm handling a REGISTER transaction? Here's a simplified version of my routing block (not far from reality): ``` request_route{ route(AUTH); route[AUTH]{ if (is_method("REGISTER"){ if(no_auth_header){ www_challenge("$td","1"); exit; } else{ t_newtran(); http_async_query("http://xxx.xxx.xxx.xxx:9000/auth?foo=bar", "AUTH_REPLY"); } } } route[AUTH_REPLY]{ xlog("L_INFO", "route[HTTP_REPLY]: status $http_rs\n"); } } ``` Best regards! -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3009 You are receiving this because you are subscribed to this thread.
