Hello everyone.
I have installed ICELPD on a system with Fedora Core 4 and CUPS 1.1.23-15, following yours instruction under j.river ftp site ( I have already successfully installed ICELPD with previous version, Fedora 1, 2 and 3). When I print, with lpr command, no file comes put into /usr/tmp/printer/icelp_jobs directory, and printer appears disabled. If I launch cups with debug there is the following message into cups log file /var/log/cups/error_log:

All configuration files have right attributes like other old version of Fedora.
This is the entry manually created in /etc/cups/printer.conf :
#</Printer>
<Printer S1>

Location
DeviceURI icelpd://S1
State Idle

JobSheets none none
QuotaPeriod 0

</Printer>

Thanks

Looking at the 4th line from the last in the error log there is a permission denied error. Perhaps the icelp_jobs dir does not have the permissions set for icelpd to be able to write to it.

Hi jimn
I've tried to create manually the directory /usr/tmp/S1/icelp_jobs, with the correct permission and to insert at the beginning of the script /usr/lib/cups/backend/icelpd the command line:
echo "START ICELP!!" > /tmp/cups.log
but file /tmp/cups.log doesn't come create.
It seems that's not executed the script /usr/lib/cups/backend/icelpd for some reason.
Thanks

What permissions do you have on the script itself?
ls -l /usr/lib/cups/backend/icelpd

[m.sperry]

The permissions of /usr/lib/cups/backend/icelp are 755 or -rwxr-xr-x

[Bob]

Who is cups running as?

ps -ef  | grep cups

First field.

[m.sperry]

Here is who run cups:

root      1857     1  0 08:55 ?        00:00:00 cupsd

Thanks.

1.1.23 works fine on my machine with the backend from the CD.
It looks like cups has the wrong permissions for the printers.conf file in /etc/cups as well. You should check your permissions on all of the cups related files/directories, it appears that your cups install is broken. I'm sorry I can't be more specific.

Hello Bob and Jimn
I've resolved !!
I've seen that Fedora Core 4 has activated SElinux.
I've put the line SELINUX=disabled in file /etc/selinux/config and cups work fine.
Thanks for the aid and Merry Xmas

[Bob]

Excellent!

Thanks for the report. I'm sure it will help others too!!!
