The Trans Pacific Partnership Trade Deal Threatens Innovation

Scary stuff actually. The agreement is to benefit existing corporations and stifle new initiatives. http://www.theglobeandmail.com/report-on-business/rob-commentary/trans-paci… -- Stephen

Interesting essay on filesystem consistency
by Christopher Browne 24 Dec '15

24 Dec '15

http://danluu.com/file-consistency/ I found it interesting that ReiserFS was pointed at as having amongst the best handling of errors, passing them back sensibly to applications. Also interesting was that they pointed at using SQLite as a way of mostly hiding applications from worrying about such troubles. Also entertaining was the notion of "MBox considered harmful"; makes me like MH and Maildir all the better, as they have the merit of storing a message per file, so that there's fewer concurrency issues surrounding re-opening files and rewriting them. (Possibly I'm wrong, and the problem just shifts to directory metadata access...) -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"

This will include a discussion of neovim, colours, dealing with your vimrc, mappings, buffers and tabs, sessions, plugins, VimScript, and possibly a couple other topics. ## 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 The Imperial Pub (54 Dundas St East) for refreshments and more socializing. # 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.

SSH Agent Forwarding
by Giles Orr 20 Dec '15

20 Dec '15

A couple days ago I discovered the joys of SSH agent forwarding. But with that, I discovered this warning in the man page: "Agent forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the agent's UNIX-domain socket) can access the local agent through the forwarded connection. An attacker cannot obtain key material from the agent, however they can perform operations on the keys that enable them to authenticate using the identities loaded into the agent." I've read this about five times because as far as I can tell, all it's actually saying is "you need to trust your remote system." So please correct me if I'm wrong: it's saying that IF someone on the remote system has a privilege escalation (or is root), then they can authenticate using any keys in your agent (but not get the keys). Is that correct? And today I found this: https://heipei.github.io/2015/02/26/SSH-Agent-Forwarding-considered-harmful/ He attacks with "It is meant as an easy way to connect to a host A with your SSH key and from there connect to another host B with that same key. This obviously is only needed if you cannot connect to host B directly from your workstation." I was immediately scratching my head, because my use-case is to load my keys on my workstation, then SSH to a remote host where I do git and/or ansible stuff that needs a key. I can connect to "host B" (the git host) from "my workstation," but the work is better done on "host A." With agent forwarding, I don't have to store the private key on the remote machine, or (re)load an SSH key. So I see that agent forwarding might be unwise if you don't trust the administrator or the machine is compromised (and yes, you can never be sure a machine is secure), but if you're worried about the security of the remote host, storing private keys on it and reauthenticating seems worse. Am I missing something? -- Giles http://www.gilesorr.com/ gilesorr(a)gmail.com

[GTALUG-Announce] Meeting Tomorrow at 7:30pm with Christopher Browne and Scott Sullivan
by Myles Braithwaite 20 Dec '15

20 Dec '15

<http://gtalug.org/meeting/2015-12/> # Terminal Multiplexers and PXE Boot ## Screen, Tmux, Byobu, the Secret Terminal Brains!!! ### Christopher Browne GNU Screen has been lurking around since the 1980s, as a kind of "tiling window manager atop curses". BSD folk spawned an analogue called tmux in 2009, offering both additions and removals of functionality. Byobu offers a harmonization, and (arguably) better user experience. We'll look at some usages, use cases, and see how frequently Byobu Hollywood crashes. ## Good Bye Boot Media! (or, don't copy that boot floopy) ### Scott Sullivan A tour of how network boot/install can save you ever having to burn a DVDs or USB drive. ## 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 The Imperial Pub (54 Dundas St East) for refreshments and more socializing. # 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.

by Christopher Browne 18 Dec '15

18 Dec '15

Just had something pass through my mailbox, not interesting to me, but possibly of some interest to others. Apparently Symantec is doing some Toronto-based OpenStack stuff in their security area, so needing Bash/Perl folk with exposure to OpenStack. Job title seems to be... "Software Developer Cloud Monitoring Systems" -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
