My automatic UUCP dialup doesn't work anymore, I think it's related to cron not running the uucp crontab script.
Any suggestions?

What system are you running ?

On some systems the cron demon creates a pipe file called FIFO
which, if from some reason, the cron demon exited badly it cannot run again unless this file is deleted manualy.

Thanks for your quick response Eric.

The system is running SCO OS5.
Where should I go for this fifo file and can I delete it without harming the integrety of the system?
The system is running in a production environment so I can't risk doing something wrong.
Does cron daemon pick up the entries automatically, or do I have to restart a specific crontab? (I only have the root account)

Forgive me if I sound silly, but Unix is beyond my expertise. Could you guide me some more?

TIA,
Henrie.

Henrie,

1) Check to see you have a cron process running.
2) Check the cron demon (cron, crond, in.crond, ....) man page
   see where that FIFO file is created. The location differs
   from one UN*X to another.
3) Make sure the demon is not running.
4) Delete the file.
5) Run the cron demon.

The system would not be affected. The single process
is responsible for all the crontabs and the "at" jobs.

Luck,

-Eric.

Thanks Eric, the problem is solved.
There were about 25(!) cron processes running. We had to restart the system with different settings and UUCP runs perfect now.

CU,
Henrie.
