Hi All !
I'm implementing SER, SEMS server, I've configured fifo as communication method between them (folowing install manual). In ser.cfg I've enabled conference part in INVITE message route handling as follows :
if (uri=~"sip:100.*@") { if (!t_newtran()){ sl_send_reply("500","Could not create transaction"); break; }; t_reply("100","Trying - just wait a minute !");
# assumes that Sems configuration parameter 'socket_name=' # has been set to /tmp/am_sock
if(!t_write_req("/tmp/am_fifo","conference")) { t_reply("500","error contacting sems - in uri check 100"); }; break; };
I can make a call on sip:100.*, but I don't have received any announcement and in /var/log/syslog I see following problems with SEMS and more oftenly with fifo permisions:

Hello,
probably you are starting sems as another user than ser?
please make sure that you set in sems.conf:
send_method=fifo fifo_name=/tmp/am_fifo ser_fifo_name=/tmp/ser_fifo
and put # before socket_name and ser_socket_name.
in ser.cfg: fifo="/tmp/ser_fifo"
and make sure that 1)the user that starts sems has write permission to files created by the user that starts ser (e.g. start them both as the same user) and 2) both users have write permission in /tmp and there is a little space left on the file system. hth Stefan

Hi,
I had configuration as you wrote, it's described in the install manual, but I cheched it again. No results. I'm sending you my advance.
I setted up cfg files as you wrote, after that in /tmp folder is created am_fifo file by root user with 644 permissions. There is not /tmp/ser_fifo file. Call on the sip:100 is terminated immediatelly, with error log inside syslog, no write permissions. There is still not created /tmp/ser_fifo file.
I changed /tmp/am_fifo permissions on 666 manually, I've added to ser.cfg cmd: sock_mode=0666, restart ser process and made call on sip:100 (call looks like success, UA report connected, but no announcement, no voice), ser created /tmp/ser_fifo file with 666 permissions now, but there is also a new file created by root user, /tmp/00007A9854930305 with 644 permissions and in my syslog there is an error log

They have.
----------------------
I do not understand, why reply pipes are cretaed with 644 permissions? And if did, why there is a write permission error problem?
I've also tried to setup socket communication, there have been also some write error problems, which looks also like problems with permissions. But I didn't research it so carefully.

Hi,
You have right! Actually I found that ser is running as user ser and group ser, when I started sems as user ser and group ser, it is working ! Great!
Thanks for you help

This fifo is created by sems, it is the fifo through which the reply to the request is sent from sems to ser. you can control the permissions on this reply fifo by setting umask before you start sems.
