enabling SElinx
by Peter 14 Sep '15

14 Sep '15

Hello, I have two questions. 1.How do I enable SElinux on my Linux mint 17 system? I just want simple default settings useful for an average user that mostly does web browsing.By the way I have tried google and found all of the information I looked at about enabling SElinux very confusing.I presume the following website is the main source of information on SElinx http://selinuxproject.org/page/Main_Page but I could not find how to enable SElinux from it.If this information is not on the website in a simple form my next question is 2.Why not? Please consider this question very carefully before answering. I am thinking many things to do with Linux are deliberately made confusing by saboteurs.Maybe I am completely wrong but as a Linux beginner that is a strong impression I am getting. regards Peter

Thanks Glen for your great help last Sat, and also Daniel's, in finally figuring out what exactly happened to Justin PC's failure to partition the SSD for his Linux distro. Your explanation here in luv main list in clear technical details on the whole issue is certainly of great value to anyone who encounter similar issue in future! I'm sure this tricky problem will be solved on or before our next LUV Beginners Workshop.

The options "legacy", "hybrid" and "PATA" are worse choices for Linux. Erratum: current hardware seems to add NVMe, which appears to be better? https://en.wikipedia.org/wiki/NVMe_vs_AHCI > using the parameter 'noatime'. The default should be relatime (check /proc/mounts), which should be near enough. Changing it to noatime will break a handful of programs, but you probably don't use them anyway.

Hi Chris, Thanks for your update. This is great! This means with the newer distros nowadays, we can basically treat SSD no different from conventional hard disks - when come to disk partitioning or formatting. I remember 2-3 years ago when I was installing Ubuntu onto my 2nd generation eeepc with SSD, I got instructions at the time to skip the swap space all together. Can I assume that with new distros on SSD - swap space is back in again? How about the "reserve 7% for overprovisioning" suggestion? Do you think it is still valid now? Anyway, the focus for Justin at the moment is to get his SSD to install Ubuntu 14.04 without error. Let us know how you go, Justin. :-) Wen On Mon, Jun 8, 2015 at 11:49 AM, Chris Samuel <chris(a)csamuel.org> wrote: > Hi Wen, Justin, > > On Mon, 8 Jun 2015 09:01:26 AM Wen Lin wrote: > > > Another key point: A Solid State Drive is worn down relatively quickly by > > write actions.

linux noob - install problems, installfests?
by Justin Fisher 31 May '15

Hi all, Total linux noob here trying and failing to install ubuntu 14.04. I would love to know if there is an installfest planned sometime soon so i can finally get the OS installed. if not i would be super grateful for any help. i posted my issue on askubuntu.com but not got any helpful responses yet, here is the link: https://askubuntu.com/questions/626934/cannot-install-ubuntu-14-04-on-new-s… basically i keep getting the "the ext4 file system creation in partition #1 (0,0,0)(sdd) failed" message when trying to install onto a brand new SSD. when i try to format and partition manually i get the "Error synchronizing after initial wipe: Timed out waiting for object (udisks-error-quark, 0)" message. If anyone can give me some pointers, i would really really appreciate it. thanks! Justin

slow file copy

hi the file is about 500MB, the source is local disk and the sink is a NFS mounted drive connected over 1Gb/s ethernet. The copy starts with a burst at 20MB/s then slows to less than 100kB/s. So the real time should have been about 30s not 13m30 ------------------------------------- $ time cp video.mp4 /media/audio/video/other/Salamander/video.mp4 real 13m30.489s user 0m0.004s sys 0m0.860s ------------------------------------- There are no entries in /var/log/messages on the sink server (Centos 6.6) and only many of these on the source machine (Fedora 20) Nov 12 11:35:42 hvamm systemd-udevd: failed to execute '/usr/lib/udev/socket:@/org/freedesktop/hal/udev_event' 'socket:@/org/freedesktop/hal/udev_event': No such file or directory. smart test on the drive shows no errors and hours=5330 (222 days), drive is 1TB Seagate where next to look
