Something like - as root... # ls -l /dev/lp0 # echo 'KERNEL=="lp0", SUBSYSTEM=="printer", MODE="0666"' >>/etc/udev/rules.d/99-local.rules # udevadm trigger # ls -l /dev/lp0 Which puts a new rule in for the device, and causes it to be reloaded. See http://reactivated.net/writing_udev_rules.html if that doesn't "just work". But I have to confess I've never needed to do this in anger since udev was introduced*. Which should tell you something given this is part of my day job. The default for all devices is 0660, so it is very unlikely that a change to the permissions of /dev/lp0 is the cause of the problem, far more likely you told the software to do this with the wrong username, or possibly you installed some printer related software which broke stuff. If I were you I'd be checking access times on /etc/cups/cupsd.conf and comparing it to the default. Also check say dpkg log and see if you have installed something you forgot about or installed a security fix. Simon * Actually I have a blog entry about a bug in "cu" where you can't run it as root, which I think I could workaround with udev, but I filed a bug report instead. But it makes the point this is relatively obscure stuff just to get printing working again. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
