[Serusers] SER <==> SEMS fifo permisions problem

[Stefan Sayer]

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.
