Adam Thompson demonstrated installing CentOS 5.x and Ubuntu 11.10 under VMware, and discussed their relative footprints in a virtual environment. The conclusion? Ubuntu (at least, right out of the box) seems to be much lighter, both in terms of memory and CPU usage.
Sean Cody presented Hard Core SSH, where he showed us how he does VPN tunnelling using SSH and tunnel devices, and a few other ssh tricks like session mixing and ad-hoc port forwarding.
Sean has made his presentation slides, in PDF format, available online.
January’s RTFM was brought to you by the letter “c” and Michael Doob, who presented cron(8) and the crontab(1) command.
The January meeting started off with the usual round-table discussion, with topics including alternatives to Gnome and KDE, clock issues in Linux under VMware, feedback on the last newsletter, routing quirks in Linux, and multi-booting under EFI.
As the holiday hustle and bustle gets into high gear, we took it easy this month, with a longer-than-usual round-table session, followed by a time for mingling and nibbling on munchies (instead of the usual, short coffee break).
We have a portion of the round-table discussion as this month’s podcast.
This was your chance to try out IPv6 without having to set up a tunnel. Presenter Mark Jenkins brought a wireless access point and provided auto-discoverable, IPv6-only access to everyone at the meeting, with real public addresses. (Unfortunately, the tunnel for upstream failed due to port blocking.)
Mark’s presentation provided some basic theory, showed how to do static configuration on GNU/Linux, and reflected on how the transition to IPv6 could play out. Mark also gave some pointers on managing reverse DNS entries with the aid of the $ORIGIN keyword in BIND, and the ease of configuring the route advertisement daemon (as used for the demonstration) was shown.
Mark has made his presentation slides, in ODP and PDF format, available online. (This work is licensed under the Creative Commons Attribution-Share Alike 2.5 Canada License.)
Our November meeting started with the usual round-table discussion, moderated by Sean Cody.
Dropbox is a free file sharing service with client support for Windows, MacOS X, Linux, and even some mobile platforms. It lets you automatically replicate files to any of your configured clients, share them with other users, or access them from the web.
In this presentation, Gilbert Detillieux showed Dropbox in use, and showed the installation of client software under Linux.
What happens when you trash your MBR? In this presentation, Rob Keizer discussed ways to get your system up and running again quickly.
Unfortunately, due to technical problems, we don’t have an audio capture of the whole presentation, only the Q and A session that followed.
Our October meeting’s RTFM topic featured Michael Doob, who talked about using the rsync(1) command.
Bad Behavior has blocked 40 access attempts in the last 7 days.
