ERROR: Error opening OpenSIPS's FIFO /tmp/opensips_fifo

Alejandro Recarey
Hello everybody,

I have just made a fresh install of OpenSIPS 1.6.1 using the
http://debian.leurent.eu/ mirror.

I am using debian lenny 5.0. I have read all of the tutorials and I
believe I have a working configuration. OpenSIPS is running and my cfg
file is loaded without problems.

However, whenever y try to run the command opensipsctl ul show, or
opensipsctl monitor I get the following error ERROR: Error opening
OpenSIPS's FIFO /tmp/opensips_fifo

Yes, I have the line modparam("mi_fifo", "fifo_name",
"/tmp/opensips_fifo") uncommented and the mi_fifo module is also
uncommented. The file /usr/lib/opensips/modules/mi_fifo.so exists.

What am I doing wrong??

I am attaching my opensips.cfg file contents.

Regards,

Alex

RES: ERROR: Error opening OpenSIPS's FIFO /tmp/opensips_fifo

Flavio Goncalves-2
Add the following parameter

modparam("mi_fifo", "fifo_mode",0666)

Just in case, check your opensipsctlrc file. This file controls where
opensipsctl finds the FIFO.

Assunto: [OpenSIPS-Users] ERROR: Error opening OpenSIPS's FIFO
/tmp/opensips_fifo

Hello everybody,

I have just made a fresh install of OpenSIPS 1.6.1 using the
http://debian.leurent.eu/ mirror.

I am using debian lenny 5.0. I have read all of the tutorials and I
believe I have a working configuration. OpenSIPS is running and my cfg
file is loaded without problems.

However, whenever y try to run the command opensipsctl ul show, or
opensipsctl monitor I get the following error ERROR: Error opening
OpenSIPS's FIFO /tmp/opensips_fifo

Yes, I have the line modparam("mi_fifo", "fifo_name",
"/tmp/opensips_fifo") uncommented and the mi_fifo module is also
uncommented. The file /usr/lib/opensips/modules/mi_fifo.so exists.

What am I doing wrong??

I am attaching my opensips.cfg file contents.

Regards,

Alex

Re: ERROR: Error opening OpenSIPS's FIFO /tmp/opensips_fifo

Alejandro Recarey
Hello Brian,

I'm running OpenSIPS as opensips:opensips.

Although I checked that /tmp/ has chmod 777, I created the opensips
user as a system user so it might be more restricted.

Maybe that is the problem? I don't mind running OpenSIPS as root, as
it will be the only service running on my box (it is a dedicated
OpenSIPS server).

Where do I configure a new user, because I can't find the entry in
opensips.cfg, opensipsctlrc or osipsconsolerc? Or should I just give
the opensips user the required permissions?

Thank you for your help!!

Alex
