Sudo in Script
by Stephen 15 Sep '19

15 Sep '19

I do work in a LAMP system. When debugging I like to clear the Apache error file and save as null. To continue error logging I have to restart Apache. 1) Not a big deal, but is there an easier way? I restart Apache in a script file that requires a Sudo command. That requires a password. 2) Can I provide the password in the script file to avoid the prompt and save a little time? Thanks! -- Stephen

York University WiFi and Certificate Authority root certificates
by D. Hugh Redelmeier 14 Sep '19

14 Sep '19

We needed to set up WiFi on a notebook with Fedora at York University. The IT staff were steadfastly unhelpful. I'm posting this in case someone else needs to set up WiFi at York. This page is for Students: <http://student.computing.yorku.ca/airyorkplus/#squelch-taas-toggle-shortcod…> In this case, the user was faculty, but the faculty page is less helpful. We looked at how Windows and ChromeOS were configured and did something similar on Fedora. One slightly tricky part was filling in the "CA certificate" field. We ended up using /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem This is the bundle of CA root certificates known to and trusted by Firefox, OpenSSL, and perhaps NSS.

New Rogers offerings and guest access
by David Collier-Brown 13 Sep '19

13 Sep '19

I have an old Rogers cable setup, and the new one is cheaper and in principle less restricted. Does anyone have one and know if they allow "guest" accounts on their wi-fe hubs, like Open WRT does? I have friends/neighbors I want to give bandwidth to. --dave -- David Collier-Brown, | Always do right.

Decrypting and Re-encrypting Network Traffic
by Giles Orr 11 Sep '19

11 Sep '19

Decrypting and re-encrypting network traffic is becoming more and more popular. I think it's an appalling violation of both trust and privacy, but corporations seem to feel justified to "protect their network" (it's not necessary to explain the logic to me, I get it ... I'm just more about individual rights). Or maybe they're just doing it to mine your data, depending on the context. There seem to be two circumstances (this is just about web traffic): - a private computer on a shared network, ex. you take your personal computer to a coffeeshop - a company computer on a company network, ex. you sit down at your work computer I think I understand the latter: with a company computer on a company network, all that's necessary is to push a trusted certificate and all future communications will be done with that newly trusted cert and, well, you're hosed. Everything you send is examined and re-encrypted with the receiving site's certificate at the company firewall. Can this be detected? Can this be prevented? It seems that some shared networks (ie. the coffeeshop in the above examples) manage to do this to people: is this only possible if they convince you to install something, and presumably that install package includes a certificate? Or is there another way? -- Giles https://www.gilesorr.com/ gilesorr(a)gmail.com

<https://gtalug.org/meeting/2019-09/> # Fear and Loathing and Mailing Lists with Evan Leibovitch In today's environment of spambots, blacklists, European privacy laws and Canadian anti-spam regulations, sending out bulk email these days is not for the timid. This presentation will describe one organization's search for the best way to do this. In the process it will identify some of the tools available - both open source and cloud based - and offer advice and warnings to others looking to use this method of communications. ## Location George Vari Engineering and Computing Centre 245 Church Street, Room 203 Ryerson University <https://goo.gl/maps/16oJ2> <https://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.

Regex Crossword
by Giles Orr 04 Sep '19

https://regexcrossword.com/ As the co-worker who sent this to me said, "There goes my evening!" I'm finding it a fun way to force myself to think through the minutiae of regex that I've often glossed over ... and because of that glossing over, I haven't improved as much as I might have wished. -- Giles https://www.gilesorr.com/ gilesorr(a)gmail.com
