Error message

Tom Spence_1 — Tue, 27 Aug 2002 16:24:01 GMT

Hi all,

I can connect to the server but no login prompt from my pc's terminal. So I decided to go and check with server with console. It said:

cron aborted: cannot access fifo queue

So I had to press the power button off and on... So how can I fix with that fifo?

I appreciate your help.

Tom

Hi Tom:

Check for the presence of a FIFO queue:

# ls -l /var/adm/cron/FIFO

You should see something like:

prw------- 1 root root 0 Aug 26 13:50 FIFO

The 'p' denotes a pipe. If you don't have this file or it isn't a pipe file, do:

# mknod /var/adm/cron/FIFO p

Regards!

I don't think your problem and the message is directly related. To resolve the cron issue, check this document:

Doc ID - KBRC00001046

For the login prompt issue, you may have to check the connection settings, syslog.log file, your terminal setting etc.

Hi Tom,

Were you able to login at the console? If a user was already logged in at the console then tapping return at the cron error should have returned you to a prompt, where you could have safely run a shutdown. You should avoid powercycling a running server if at all possible, always making sure it is shutdown first.

How are you connecting from your PC? Are you using a telnet connection, is the problem confined to just your pc?

regards,

Darren.

Hi

Do the following

A)If you actually have a /var/adm/cron/FIFO file.Remove it
rm /var/adm/cron/FIFO

B)Remake the pipe by running:

mknod /var/adm/cron/FIFO p

You must include the final p argument .

C)Verify the cron directories:

/usr/lib/cron

and

/usr/spool/cron

You should see
lrwxr-xr-t 1 root sys 13 Jun 14 03:43 /usr/lib/cron -> /var/
adm/cron
dr-xr-xr-x 5 bin bin 96 May 22 15:20 /usr/spool/cron
prw------- 1 root root 0 May 22 15:20 /var/adm/cron/FIFO
