Earlier I posted about a problem with my line printer spooler.
Well there is still a problem, but I think I have narrowed it down a little.
The problem is that the line printer scheduler is not running, and nothing
I do seems to get it to work.
I have recently discovered that one of the files in /usr/spool/lp, namely
/usr/spool/lp/FIFO was missing. This is not a normal file but a named pipe.
After learning that the mknod command is used to regenerate it, I tried again.
Each time I remake /usr/spool/lp/FIFO, and then run lpsched, the FIFO
disappears, and the scheduler still won't run. I have tried various permissions
and ownerships, but nothing seems to work.
Any new suggestions.
Thanks

Some things to do when there's nothing better to do: mknod /tmp/xx p cat /tmp/xx & echo I'm a little FIFO, little FIFO, little FIFO >/tmp/xx Notice how a named pipe hangs around till you specifically remove it, i.e. rm. One can putts for hours thinking of new and improved ways to waste your time.... You can even change it's mode so EVERYONE can play! -Rob -- -Rob
