LTSP | LTSP5 Local Devices
19 Nov 2010
You’ve inserted a disk or memory stick in your thin client, and nothing happened, what next?
Check lts.conf
Each user you wish to be able to access their local devices needs LOCALDEV = True in lts.conf, alternatively you may add to the ‘[default]’ section to make this global.
[192.168.1.198]
# Joe Bloggs Desktop
LOCALDEV = True
Check user is in fuse group
# groups userid
userid satff users audio fuse
If they are not in the fuse group then:
# adduser userid fuse
Check lts.conf settings are reaching client
A simple typo can mean that your carefully crafted lts.conf file is not reaching its target audience. To test, boot up the thin client and ctrl+alt+f1 to get to the console, login as root and type the following:
See LTSP Client Root Password if you are unable to log into the client.
# getltscfg -a
This will give you a list of all the settings that apply to this particular client, including any default settings. You need to check that you can see the above LOCALDEV=”True” is visible.
Check logs on client
# tail -f /var/log/syslog
Then try inserting the device, and you should see the detection - look for errors that might indicate what has gone wrong.
Check UDEV can see drive
Still on the client:
# udevadm info -q all -n sda1
Replace sda1 with the required device, e.g. sr0 for a cdrom etc.
