I can't seem to figure out what to change to rectify this - I've tried changing the owner and group on the xsane executable, but this didn't work. The permissions for the xsane executable seem fine. I have added myself to the scanner group, but this doesn't seem to have any affect. Also, despite the fact that the device can be set up wirelessly, I have not done this - I have the unit connected to my computer via USB cable. Any of you gurus have any ideas? Hi Colleen, I also have one of those All-In-One printers. To get it to work, I added the saned user to the following groups: - lp - usb - scanner I'm not sure, but I think usb is sufficient for the scanner, but with these, it works on my system. -- Joost

Your scanner's dev node has can only be read by root, the easiest way to
fix this is with a udev rule, as the node name changes each time you
connect the scanner. This rule works for me, I'm in the canner group,
just change the product and manufacturer strings to match
SYSFS{product}==CanoScan, SYSFS{manufacturer}==Canon, GROUP:=scanner,

[gentoo-user] /etc/conf.d/net tries to do too much
I configured my laptop as a wireless AP with hostapd. It works great as long as I 'ifconfig wlan0 192.168.1.1'. I can have /etc/init.d/net.wlan0 started automatically with hostapd, but I can't come up with an /etc/conf.d/net config that will work. It always fails by saying it can't set master mode or other parameters. I think hostapd is supposed to handle all of that except the IP configuration, but /etc/conf.d/net wants to do more than just the IP configuration. Does anyone know the right way to handle this? - Grant

[gentoo-user] nfs-utils broken on ~amd64?
Anyone else having problems mounting nfs shares with nfs-utils-1.2.1? 'mount.nfs' complains I'm passing it a bad nfs option no matter what options I give it, including no options. Strace shows that nfs.mount is passing a weird-looking IP address string to the 'mount' system call (man 2 mount), e.g.: mount(k2:/media/d, /mnt/nfs, nfs, 0, addr=192.168.0.100,vers=4,client...) = -1 EINVAL ^^ When I revert back to nfs-utils-1.1.4-r1 the IP address string is back to normal and the mount works correctly, e.g.: mount(k2:/media/d, /mnt/nfs, nfs, 0, addr=192.168.0.100) = 0 Something is tacking on those extra chars after the IP address, but I'm not sure yet where that string is actually generated. Any ideas?
