Experimental Physics and
Industrial Control System

We run IOCs in Gnu screen sessions, accomplishing all three of your requirements. The screen sessions are started in multi-user mode, through some scripting in the init system. This is accomplished on headless systems by exploiting the 'stuff' command of the screen applicaton to stuff commandlines into the screen session to launch the IOC application(s). Logging is done by screen, and log rotation using conventional logrotate tools.

Users use ssh to connect to the IOC host, and then connect to the screen session. This part is augmented with a GUI tool which runs on a common server host that lets users browse lists of IOCs and connect to sessions by clicking on menu items.

We use procServ to handle tasks 1 and 3, and logrotate for task 2.  A
simple etc/init.d script can be used to start the procServ/IOC.

*Subject:* Asyn daemon + console + log

Hi guys,

I was wondering if someone could help me implement the following:

    * Already done: I need to start my Asyn IOC as a daemon so that it
      is executed at startup (A simple /etc/init.d/ scripts is doing the
      job)
    * Already done: I need to store all the outputs of my IOC into a
      file (into /var/log/asyn/xxxxx.log with a logrotate to avoid
      getting a problem with size)
    * I want the user able to connect to the epics-ioc console (Maybe
      through /dev/ttySxx)

I have manage to get the two first thing working but I can not get the
combination of the three. Someone has an idea, is it possible to access
to the console?

Maybe running the IOC as a daemon is not the best solution, but I would
really like to have my IOC started when I power on my rack.
