The problem was in the argument sent to the fifo. Apparently the path to the reply fifo cannot have a path. So ":ul_dump:rfifo\n" <---works ":ul_dump:/tmp/rfifo\n" <---does not work because SER does not like the path. I wonder what makes SER know to use the 'rfifo' in the /tmp directory? -----Original Message----- From: serusers-bounces(a)iptel.org [mailto:serusers-bounces(a)lists.iptel.org= ] On Behalf Of Leo Sent: Thursday, April 21, 2005 9:37 PM To: marian.dumitru(a)voice-sistem.ro Cc: serusers(a)lists.iptel.org Subject: RE: [Serusers] Help Using SER FIFO "ser_fifo" Marian, Thank you for the fast response and advice, but I am still stuck. I made fifo by doing an 'mkfifo rfifo' in the /tmp directory to create a fifo called 'rfifo'. Then I changed the permissions to "666". Then from the command line I did a 'cat rfifo' which waits for something to be written to 'rfifo'. Then I modified the PHP script in this e-mail string to reply to 'rfifo' instead of 'delthis.txt'. However, the cat on rfifo never returns. I see nothing the in SER log about why. If I open up another command window and send something to rfifo, it does return. So I know rfifo is working, it is just that SER does not seem to be writing to 'rfifo'. I am stuck.

Try to monitor SER logs to trace your problem.
