Anyone here using Manjaro or OpenSUSE?
by Evan Leibovitch 10 Sep '18

10 Sep '18

Hi all. I'm looking to install a new distro, after using Mint and Kubuntu for a long time. I'm trying to choose whether to try Manjaro or OpenSUSE. Sure, I can install both and can look around. But I'm wondering is there is anyone here who uses either of these distros who might be aware of issues not readily apparent. Intended desktop is KDE. Note: I want to be able to use Dupeguru, Spotify, Skype and Signal, apps that under *buntu require auxilliary PPA repositories. Some of these are dealbreakers if I can't use them. All answers are appreciated. The system is to be installed on an SSD, if that makes a difference. Thanks! -- Evan Leibovitch, Toronto Canada @evanleibovitch or @el56

Any Debian User Groups in the GTA?
by Sergio Durigan Junior 06 Sep '18

Hi there, Do we have any Debian User Groups in the GTA? I've been living in Toronto for the past 4 years and never even heard of one, which is a bummer. I'd like to do something this weekend to celebrate Debian Day + 25 years of the project. On a side note: any DDs/DMs on this list? Maybe we can start a group ourselves :-). Thanks, -- Sergio GPG key ID: 237A 54B1 0287 28BF 00EF 31F4 D0EB 7628 65FC 5E36 Please send encrypted e-mail if possible http://sergiodj.net/

Swappiness
by Evan Leibovitch 06 Sep '18

06 Sep '18

I have a desktop that, to me, seems like it's running to swap just a little to often and coming back to RAM just a little slower than I'd like. What are the ill effects, on a desktop, of lowering swappiness down from the default of 60? Thanks! -- Evan Leibovitch, Toronto Canada @evanleibovitch or @el56

[GTALUG-Announce] GTALUG Meeting on Tuesday 11 September at 7:30pm

<http://gtalug.org/meeting/2018-09/> # How Open Source Destroyed the Past, Created the Present, and Will One Day, Save the Future. with Marcel Gagne We are living in a world built on, and by, Open Source. Every Web page we visit, every message we send, every video we watch, every second of our connected lives owes its existence to an idea that's part technology, part ideology, and part philosophy. That idea would eventually infect millions, tearing down old business models, cultures, and even livelihoods, as it went. It's an idea that would redefine the meaning of 'free' and 'freedom'. But it would also create the world we live in, a world that is still struggling to adapt to the changes, a world where the idea that is "free and open" will, in time, define the future. ## Location George Vari Engineering and Computing Centre 245 Church Street, Room 203 Ryerson University <http://goo.gl/maps/16oJ2> <http://www.openstreetmap.org/way/23447525> ## Schedule * 6:00 pm - Please discuss on the general mailing list (i.e. <talk(a)gtalug.org>) where you want to go for dinner. * 7:30 pm - Meeting and presentation. * 9:00 pm - After each meeting, a group of GTALUGers move to The Imperial Pub (54 Dundas St East) for refreshments and more socialising. # Code of Conduct We want a productive happy community that can welcome new ideas, improve every process every year, and foster collaboration between individuals with differing needs, interests and skills. We gain strength from diversity, and actively seek participation from those who enhance it. This code of conduct exists to ensure that diverse groups collaborate to mutual advantage and enjoyment. We will challenge prejudice that could jeopardise the participation of any person in the community.

fail2ban problem
by Michael Galea 01 Sep '18

01 Sep '18

I am experiencing what I believe is a DNS amplification attack on my bind9 DNS server. I'm seeing very of the following on different IPs 20:11:53.977254 IP 108.234.250.76.62926 > 69.265.222.253.53: 50679+ [1au] ANY? USADF.GOV. (38) My server responds 20:11:53.977776 IP 69.265.222.253.53 > 108.234.250.76.62926: 50679 Refused- 0/0/1 (38) I imagine the IPs are spoofed. I have installed fail2ban in order to address the problem. Various howtos detail how to configure bind to log to /var/log/named/security.log and setup fail2ban. The security.log is filling nicely with lots of "29-Aug-2018 20:23:07.798 client @0x7fa1d013b990 66.69.234.170#29024 (USADF.GOV) query (cache) 'USADF.GOV/ANY/IN' denied" and fail2ban is indicating "Jail 'named-refused' started" but it never actually bans an IP. 2) I used fail2ban-regex to test the security.log line against fail2bans named-refused regex, but its doesn't match! So I have to conclude either debian bind9 changed the log output or fail2ban git it wrong. I'm using the latest fail2ban from debian. Has anyone else got this to work? -- Michael Galea
