[OpenSIPS-Users] FIFO very fragile

[Dave Singer]

Brett,
I believe you need the full path to the reply fifo.
Try:
echo -e ":address_dump:/tmp/my_fifo\n\n" > /tmp/opensips_fifo

you may also have a permissions ( chmod a+w /tmp/my_fifo ) and/or SELinux
issue (very likely if SELinux is enabled, I posted a howto for SELinux in
the list a number of months back)
