A question about boot
by David Collier-Brown 05 Jan '17

05 Jan '17

Who can talk about (intel or arm) boot? I'm looking at a problem that can be solved by setting up a device at boot time and not letting the OS have the privilege or perhaps the physical ability to change it... --dave -- David Collier-Brown, | Always do right.

Bash on Ubuntu on Windows
by William Park 03 Jan '17

03 Jan '17

Hi all, I just tried "Bash on Ubuntu on Windows" (yes, it's real title). With this, there are now 4 ways of running Unix tools on Windows. 1. busybox -- single binary running on Windows. 2. Cygwin -- you download and install bunch of programs, like bash, bc, awk, sed, etc, that will run natively on Windows. 3. VirtualBox -- full VM. 4. Bash on Ubuntu on Windows -- Ubuntu 14.04 LTS command line on Windows 10 (64bit only). I kind of like it, because it's "official" and will replace Cygwin, at least. Busybox is still useful for other Windows, but as Windows10x64 becomes the standard, it will be replaced too. -- William

What Not To Backup
by John Moniz 27 Dec '16

27 Dec '16

Hi everyone, I'm backing up my system on a more regular basis and am trying to fine tune the files that I backup. I am looking for advice on what NOT to bother to backup on the /home directory. I am using rsync (took a long time and lots of trials to figure out the man page - and still don't know 90% of it) and presently have the following on my exclude_list.txt: (Note: multiple items shown on one line are just for readability, each line in the file only has one item) tmp* TMP* .cache* cache* Cache* CACHE* *CACHE *Cache *cache .cookies* cookies* Trash Trash* TRASH* Junk* junk* .gvfs Backups backups Crash* .xsession-errors* .macromedia .thumbnails .mozilla/firefox/*/thumbnails *.corrupt minidumps .local/share/gvfs* I'd love to exclude things that perhaps one would never use from a backup to rebuild a system after an accidental clean wipe of all data. Similarly, any recommendations of what I should back up outside of /home? I am thinking of things like /etc/fstab, files that would make it easier to recover from a crash or to upgrade a distro. Thanks for any advice. John.

Experience Upgrading From Fedora 24 to Fedora 25
by CLIFFORD ILKAY 24 Dec '16

24 Dec '16

Hello All, I've been using Fedora for a few years on my primary workstation, though I use Debian (stable) for servers. Whenever Fedora released a new major version, I'd do a fresh install, which based on past experience with attempts to upgrade in place was the best way. I just followed the directions here <https://fedoraproject.org/wiki/DNF_system_upgrade> to upgrade from 24 to 25. Within 20 minutes, I had a flawlessly working system. I'm very impressed. Hardware specs, in case you're wondering, are as follows. ASUS P755D with Intel i5-750 CPU, 16GB RAM /boot, /, and swap on a 120GB Samsung 750 EVO SSD /home on a 960GB SanDisk SSD /data on an 8TB Western Digital Red HDD nVidia 960GT video card (using nouveau driver) -- Regards, Clifford Ilkay + 1 647-778-8696

Rsnapshot is about the limit of what I can handle. You can set it to do daily, weekly and monthlies. For me, that's to a NAS that is (or was, until Crashplan pulled compatibility) backed up online. The only thing that's fiddly is the config file: it's very particular about tabs vs spaces. Stewart

Wireless Access Point Question
by phiscock＠ee.ryerson.ca 23 Dec '16

23 Dec '16

I recently extended our household network using a couple of TP-Link TL-PA8030P powerline adaptors. So far, that seems to work fine. The link speed at the far end is essentially the same as it is at the DSL modem. I just plugged them in and they worked. There is also a 'pair' button that creates an encripted link between the units on the network. Questions: - I'm going to add a third adaptor to the network, but these things are only sold in pairs. So I'll buy the kit of two for around $100 and have a spare one. Anyone here interested in a single unit? - The existing Sagecom modem-router has resonably decent wi-fi coverage, but to fill in a dead spot I'd like to plug in a wireless access point to one of these powerline adaptors. The Canada Computer sales person suggested the TP-Link WA901ND, but that one has terrible reviews. Does anyone have a suggestion for a suitable device? Ease of configuration is a consideration ;). Best wishes of the season to GTALug, and thanks for the advice- Peter -- Peter Hiscocks Syscomp Electronic Design Limited, Toronto http://www.syscompdesign.com USB Oscilloscope and Waveform Generator 647-839-0325

Testing Restore of mySQL Database
by Stephen 23 Dec '16

23 Dec '16

With the discussion about backups, I would like to raise a question I have had for some time. Having backups does no good if you cannot restore them. Files are rather easy to test. But how do you test restoring a database? I back it up with the usual tool. I have the docs to do the restore. But how to test to make sure that restoring works, without clobbering the active database? Thank you -- Stephen

Resizing FAT32 filesystem?
by William Park 20 Dec '16

20 Dec '16

Hi, How do you resize FAT32 filesystem? For ext2/3/4, there is 'resize2fs'. But, for msdos, GParted is the only program I can find. There must be some command-line program that can resize msdos filesystem. -- William
