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
Aug 2 09:01:55 mail /usr/sbin/ser[31229]: ERROR: open_reply_pipe: open
error (/tmp/00007A9854930305): Permission denied
Aug 2 09:01:55 mail /usr/sbin/ser[31229]: ERROR: fifo_reply: no reply pipe
/tmp/00007A9854930305
Following your instructions:
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)
They are started as root root user
and 2) both users have
write permission in /tmp and there is a little space left on
the file system.
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.

Subject: Re: [Serusers] SER <==> SEMS fifo permisions problem
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.

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:
