[Serusers] I can't append a head field in the tm module
by szj 15 Mar '05

15 Mar '05

Hi: I want to insert a header field without the script. Instead I insert it in the tm module's t_relay() function. Next is my code. The first time I use the pkg_malloc(), but ser report that: BUG: qm_*: prev. fragm. tail overwritten(c0c0c000, abcdefed) so I changed the pkg_malloc to the shm_malloc(); this time the error happend again in the different place. typedef int(*local_fp)(struct sip_msg *msg, str *txt, int flags); str *str1; char *tmp = "P-Security-Nobody: this is a test header for \r\n"; local_fp append_to_reply = NULL; str1 = (str*)shm_malloc(sizeof(str)); if(str1) { str1->len = strlen(tmp); str1->s = (char*)shm_malloc(str1->len); strcpy(str1->s, tmp); append_to_reply = (local_fp)find_export("append_hf", 1, 0); if(append_to_reply){ DBG("DEBUG: SUNZJ find apppend_to_reply\n"); append_to_reply(p_msg, str1, NULL); } } the next is gdb's output. Program received signal SIGABRT, Aborted.

Hello, I started SER performance test with sipp traffic generator on FreeBSD 5.3. After starting 300 calls per second I got the following error: Mar 14 16:35:09 devel ser[1506]: msg_send: ERROR: udp_send failed Mar 14 16:35:09 devel ser[1506]: ERROR: udp_send: sendto(sock,0x2a258ae0,568,0,0x286be26c,16): No buffer space available(55) SER send "503" the service not available. I don't use mediaproxy/rtpproxy to exclude problems there. Could someone help me with this? Thank you, Tina __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[Serusers] RE: SER and radius client not talking
by AJ Grinnell 14 Mar '05

14 Mar '05

I think I have my problem solved. I am using a Cisco CSS11800 to load balance to two SER servers. This seems to cause issues with digest authentication. Anyone have experience with load balancing SER and using digest auth at the same time?

[Serusers] SER and radius client not talking
by AJ Grinnell 14 Mar '05

14 Mar '05

I have had SER working with radius authentication on a previous server with no problems. Now that I am trying to build up a few more servers, I can not get SER to talk to radiusclient. I can run radiusclient successfully from the command line, but the last things I see when I try to authenticate against SER is: 0(17829) qm_free(0x810aa80, 0x8167bc0), called from sterman.c: radius_authorize_sterman(101) 0(17829) qm_free: freeing frag. 0x8167ba8 alloc'ed from sterman.c: radius_authorize_sterman(87) Any ideas? Im guessing it might be a library problem, but nothing is standing out to me.

Ray, I solved it but using B2BUA from vovida.org I'm not doing accounting with ser itself. Some say it introduces some delay in between the calls. At least, it do works for me.

[Serusers] SER+Radius Accounting Not Working
by Lucas Aimaretto 14 Mar '05

14 Mar '05

Hi list. I have this problem. There's something that's not working, because, when ever I set up a call, I receive both messages INVITE and BYE instantly. I think the correct way would it be to send Start messages (Acct-Status-Type = Start) upon INVITEs and Stop messages (Acct-Status-Type = Stop) upon BYEs. But this is not happening. Look ... radrecv: Accounting Request from host c0a801fd code=4, id=205, length=270 Acct-Status-Type = Start Service-Type = Sip-Session Sip-Response-Code = 200 Sip-Method = Invite User-Name = "1992001(a)192.168.1.253" Calling-Station-Id = "sip:1992001@192.168.1.253:5060;user=phone" Called-Station-Id = "sip:1992005@192.168.1.253:5060;user=phone" Sip-Translated-Request-URI = "sip:1992005@192.168.1.178:11005" Acct-Session-Id = "6dfb6640367b1ab7(a)192.168.1.113" Sip-To-Tag = "54061171" Sip-From-Tag = "39eeac148f846cb9" Sip-CSeq = "1544" NAS-IP-Address = 192.168.1.253 NAS-Port-Id = 5060 Acct-Delay-Time = 0 Sending Accounting Ack of id 205 to c0a801fd (nas linux) radrecv: Accounting Request from host c0a801fd code=4, id=206, length=270 Acct-Status-Type = Start Service-Type = Sip-Session Sip-Response-Code = 200 Sip-Method = Bye User-Name = "1992001(a)192.168.1.253" Calling-Station-Id = "sip:1992001@192.168.1.253:5060;user=phone" Called-Station-Id = "sip:1992005@192.168.1.253:5060;user=phone" Sip-Translated-Request-URI = "sip:1992005@192.168.1.178:11005" Acct-Session-Id = "6dfb6640367b1ab7(a)192.168.1.113" Sip-To-Tag = "54061171" Sip-From-Tag = "39eeac148f846cb9" Sip-CSeq = "1544" NAS-IP-Address = 192.168.1.253 NAS-Port-Id = 5060 Acct-Delay-Time = 0 Sending Accounting Ack of id 206 to c0a801fd (nas linux) Do you see ? ...Both outputs show an Acct-Status-Type = Start, but first output refers to an INVITE and second output refers to BYE message.
