encrypted partitions
by Patrick Dupre 26 Aug '16

26 Aug '16

Hello, On a laptop, I would like to setup 2 encrypted partitions with the same passphrase (this is easy). Now, when I boot the laptop, I would like to have to provide the passphrase only one time. Is it possible? Thank. =========================================================================== Patrick DUPRÉ | | email: pdupre(a)gmx.com Laboratoire de Physico-Chimie de l'Atmosphère | | Université du Littoral-Côte d'Opale | | Tel.

lirc on fedora?
by Tom Horsley 25 Aug '16

25 Aug '16

I see lirc rpms on fedora, but I wonder about the systemd integration. The /usr/share/doc/lirc-core/README.fedora file doesn't quite seem to document the actual installation. The /usr/lib/systemd/system/lircd.service file says it depends on the lircd-setup.service, which doesn't seem to have a service file anywhere. On the other hand, it might make more sense just to run lirc as my normal user when I login using a startup script. Anyone have any experience running lirc on fedora using the packages from the repo?

calendar program loops
by Jon LaBadie 25 Aug '16

25 Aug '16

Upgraded to F24 and had a big surprise this morning, a mail queue clogged by over 400,000 messages. Root runs a nightly cronjob of "/usr/bin/calendar -a" to look at each users calendar file and send notices of upcoming events. The new version loops endlessly through all the users. If I run calendar as myself without the -a option it doesn't loop. Run it as "sudo calendar -a" and I have to kill it quickly or the mail system will clog again. My google and bugzilla search did not find any comparable reports. Is anyone using this ancient command with the -a option? Jon -- Jon H. LaBadie jonfu(a)jgcomp.com

Evercookies & other malware: A different approach
by Drew Samson 25 Aug '16

25 Aug '16

As I've been contemplating this over the last few days it occurred to me tools to deal with this effectively are readily at our disposal. The bullet-proof way to deal with this is related to what I wrote a few days ago. As I mentioned, I do my web browsing inside virtualbox and virtualbox has what are called immutable images. I can make my vm disk read-only and it's easy to do. I know this is not a viable solution for some, however for those who are able to go this route it really doesn't matter what gets loose or written to obscure locations since it'll all be wiped out after a restart. Hence: no tracking and no malware possible...persistently anyway. I also looked into other ways this may be accomplished from within the OS itself. I haven't implemented or experimented with this since what works for me takes all of 5 minutes yet I list it so that perhaps it may be helpful in giving someone else a solution that works for them. Tool: firejail & firectl - from their page... *"Firejail* is a SUID program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces <https://lwn.net/Articles/531114/> and seccomp-bpf <https://l3net.wordpress.com/2015/04/13/firejail-seccomp-guide/>. It allows a process and all its descendants to have their own private view of the globally shared kernel resources, such as the network stack, process table, mount table." It also has a ready template for Firefox. https://firejail.wordpress.com/ The latest version: 0.9.42-rc1 released 7/21/16 https://lwn.net/Articles/671534/ firejail review http://www.pcreview.co.uk/threads/firejail.4069760/ another review I'm not sure if this would prevent tracking however since I haven't used the tool and don't know if it's easy to "reset" the environment once an app closes. I also considered a permissions-based approach yet after considering it it doesn't seem much different than using a gui plugin: if a browser doesn't have permission to write a cookie or run a script it would probably respond just like the gui tools banning the same. Also let me be clear my "bulletproof" comment above was only in the context of malware; not protection from a hacker/cracker since if they were able to jump out of the vm into the host...then obviously they've also left the ro env. hth.

Booting LiveCD from the Hard Disk

People, Whether I use a GRUB2 configuration to boot from the XFCE LiveCD iso or extract the files and not have to use the loopback option - I get the same problem - the boot process gets past linux and initrd and then has problems ie: [ 3.141117] localhost kernel: clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x73401d16425, max_idle_ns: 881590940111 ns [ 3.400709] localhost iscsid[324]: can't open InitiatorName configuration file /etc/iscsi/initiatorname.iscsi [ 3.400773] localhost iscsid[324]: Warning: InitiatorName file /etc/iscsi/initiatorname.iscsi does not exist or does not contain a properly formated InitiatorName.

You will note I said the boot process gets past the linux and initrd stage - so it is past the grub stage and into the Fedora boot stage - this is a Fedora problem not a GRUB2 problem . .

Dell Inspiron 17 with Fedora
by CLOSE Dave 23 Aug '16

23 Aug '16

This is just a notice for those who may care. I installed Fedora 23 on a Dell Inspiron 17 laptop. If I use the latest kernel, 4.6.6-200, the screen flickers incessantly except when the touchpad is used to move the cursor. If I use a slightly older kernel, 4.5.7-202, everything works fine. -- Dave Close
