[Serusers] about fifo

[murat]

Hello,
If I run the "serctl moni " as 'roo' , it executes not  a problem.
 But , if I run it as a not  'root'' , for example ,as "murat", I have 
following errors!.

******************************************

Error opening ser's FIFO /tmp/ser_fifo
Make sure you have line fifo=/tmp/ser_fifo in your config

**************************************************

Even I have   ' fifo="/tmp/ser_fifo"  '  lines on my default 'ser.cfg'   
  file.

Question <1>: What is the problem about this?
Question <2>: I have some SIP sicripts, and how can I run it?.

Thank you.
