I am using it on my work through K12LTSP distribution which is based on CentOS 5 (updated to CentOS 5.11). The thin clients boot fast and everything looks nice, except that USB memories don't get available when they are plugged in in the thin client. I've tried a few things but got nothing. Could you please point out the correct way of debugging this issue or any related solution? I have to say that I first tried CentOS 6 and LTSP from EPEL repository. It installed well on the server but the thin clients didn't boot up. They reported an error message saying: processor not supported. Very old hardware the one I have, I guess. Here are some of the references I've tried: - https://fedorahosted.org/k12linux/wiki/RHEL5Server - https://www.redhat.com/archives/k12linux-devel-list/2008-November/msg00050.html - http://k12osn.redhat.narkive.com/YoZTZwcE/plans-for-k12linux-el6-and-future-fedora Best regards, al.

Barry, thank you for the quick response. On the server, with all clients down, I did the following: usermod -G fuse al Then, turned on one of the clients and plugged in the USB memory in it and it didn't work. The device icon didn't appear on the desktop. The username I am using for testing is "al". And the output of "id al" command looks like the following: uid=500(al) gid=500(al) grupos=500(al),101(fuse) context=user_u:system_r:unconfined_t After testing, and having no USB icon in the desktop, I installed the k12linux-temp-release-5-1.el5 repository, and did a yum update. The action updated the dkms-fuse package to 2.7.3-0. Made some tests, and it didn't worked either. So downgrade the dkms-fuse pacakge to k12ltps orginal version and removed k12linux-temp-release from the system. I installed the yum priorities plugin and set the following configuration: /etc/yum.repos.d/CentOS-Base.repo:[base] /etc/yum.repos.d/CentOS-Base.repo:priority=10 /etc/yum.repos.d/CentOS-Base.repo:[updates] /etc/yum.repos.d/CentOS-Base.repo:priority=10 /etc/yum.repos.d/CentOS-Base.repo:[extras] /etc/yum.repos.d/CentOS-Base.repo:priority=10 /etc/yum.repos.d/k12ltsp.repo:[k12ltsp] /etc/yum.repos.d/k12ltsp.repo:priority=40 /etc/yum.repos.d/k12ltsp-macromedia.repo:[macromedia] /etc/yum.repos.d/k12ltsp-macromedia.repo:priority=50 /etc/yum.repos.d/epel.repo:[epel] /etc/yum.repos.d/epel.repo:priority=60 All other repos are disabled. Another test was editing the file /etc/udev/rules.d/99-fuse.rules to change the line: KERNEL=="fuse", NAME="%k", MODE="0666",OWNER="root",GROUP="root" to KERNEL=="fuse", NAME="%k", MODE="0666",OWNER="root",GROUP="fuse" but the USB memory icon didn't appear on the desktop, either. So, changed it back to the first line. Something I've noticed is the existence of a /home/al/Drives directory that is automatically created when I plug the memory in. This looks like a good sign to me (the USB is somehow detected and actions taken when a device is plugged in). However, such directory is empty. I've also noticed, that /opt/ltsp/i386/etc/lts.conf.readme mentions something about adding HOTPLUG = Y on /opt/ltsp/i386/etc/lts.conf so I did, but again the USB icon didn't appear on the desktop. In all tests I've made, SELinux has been in enforcing mode and I haven't seen any denial there, so far. Is there anything else I could try. I truly would like to understand what's going on here. Your help and suggestions are very much appreciated. Best Regards, al.

Also disable SeLinux and reboot server. You do have iptables turned off at boot correct? Providing you have user al added(which it looks like al is in fuse group) to the fuse group usb sticks should show an icon on desktop when plugged in. One other thing. You did have a group fuse without manually adding this group to the server,correct? Let us know your progress.

That is correct. The usb sticks I am using for testing purposes work in the server as expected.

The fuse group was there right after installing the system. There is no fuse user, just a fuse group. > Let us know your progress. No USB icon in the desktop so far after plug a memory stick in a thin client where I've successfully logged in with a username that is in the fuse group. I've made the same tests in different clients (of identical model) and nothing. So, I set SELinux to enforcing mode again and enabled IPtables at boot time again. Then restarted the server and plugged the external interface cable in to send this message. Beyond testing purposes, is there any particular reason to fully disable SELinux (or even put it in permissive mode) when no denial message is reported in the /etc/audit/audit.log file? Beyond testing purposes, is there any particular reason to fully disable IPtables when the internal interface is accepting everything from the internal network, and thin clients boot up and allow users to do login successfully on them? As far as I know, the local devices' mount process takes place through fuse, which is executed as the root user. If this is correct, and SELinux doesn't report any issue, there must not be any user-related permission issue, I guess. Some of the directories that might be affected by any type of user/selinux-related permission issue could be the following (or, could them be others?): drwx------ al al system_u:object_r:user_home_dir_t /home/al drwxr-xr-x al al user_u:object_r:user_home_t /home/al/Drives/ drwxr-xr-x root root system_u:object_r:mnt_t /media/ In the package filtering side of things, I've configured IPtables to ACCEPT all the packages in the INPUT of the internal interface (eth0) where the thin clients are connected to. However, I am DROPing all packages in the INPUT of the external interface (eth1) except those packages that have been generated from the host itself. In the case of OUTPUT and FORWARD rules they are both ACCEPTed for internal and external interfaces. See the output of iptables -L -n -v command below: Chain INPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 1348 1733K ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 2281 1722K ACCEPT all -- eth0 * 0.0.0.0/0 0.0.0.0/0 144 30506 Internet_services all -- eth1 * 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 1348 1733K ACCEPT all -- * lo 0.0.0.0/0 0.0.0.0/0 2438 2668K ACCEPT all -- * eth0 0.0.0.0/0 0.0.0.0/0 83 12176 ACCEPT all -- * eth1 0.0.0.0/0 0.0.0.0/0 Chain Internet_services (1 references) pkts bytes target prot opt in out source destination 0 0 ACCEPT icmp -- * * 0.0.0.0/0 0.0.0.0/0 icmp type 255 23 19604 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 121 10902 REJECT all -- * * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Would it be in the /etc/exports file? ## LTSP-begin ## # # The lines between 'LTSP-begin' and 'LTSP-end' were added # on: vie ene 2 15:18:15 2015, by the ltspcfg configuration tool. # For more information, visit the LTSP homepage # at http://www.LTSP.org # /opt/ltsp 192.168.0.0/255.255.255.0(ro,no_root_squash,sync) /var/opt/ltsp/swapfiles 192.168.0.0/255.255.255.0(rw,no_root_squash,async) ## LTSP-end ## Would it be in the /opt/ltsp/i386/etc/ltsp.conf file (comments and empty lines removed from output)?

Yes. I've tried for almost two weeks and didn't find a solution, sadly. I couldn't install a higher version of CentOS because the thin clients report unsupported processor at boot time so, I opted to install Edubuntu 14.04 LTS which, I must say, has been impressively good detecting the old hardware I am administering. Now, the thin clients boot fast, memory sticks worked as expected, users can listen music while they surf the web, and the system has updates until 2019.

Message-ID: <1422665898.6573.23.camel@server1.eazylivin.net> Hello All, Just thought this may be of interest to someone out there. Put together a driver package that includes hostapd,for the cheap Realtek rtl8188cus usb mini dongle that will allow the wifi unit to run in master mode (access point). Have tested for 3 weeks now and works very reliably and coverage is just as good as any other G or N series Access Point. These little usb mini dongles can be bought on Ebay for $6 shipped. They do actually connect at 150mbs also. These can also be run in 5GHZ mode with the 5G hostapd.conf file in the zip file In the documentation it shows it can run as both an AP and a station,two device at same times.I never tried this. This is just the Realtek driver package stripped down with convenient install scripts to do everything easily. Hope this may be handy for someone. ftp://eazylivin.net/server/rtl8188cusap-1.0/rtl8188cusap-1.0.tar.gz Take Care, Barry
