WiFi permanently disappeared after booting test kernel
by Mike Fleetwood
Hi,
On my netbook I booted a test kernel 3.8.0-rc4+ I compiled. Now after
booting back into my regular Fedora kernel 3.6.11-5.fc17.i686.PAE my
wifi network device remains permanently disappeared. No wifi networks
displayed in Network Manager gui. Also the Network Manager syslog
messages make it look like the device has completely disappeared.
Suggestions for restoring wifi welcome.
Thanks
Mike

losing WiFi Access - prompted for password
by SternData
F18...
Over the last few days, I'm getting prompted to re-enter my password for
my WiFi network. It's not the router because no other device on the
network seems to be having problems.
Potential changes on my system include
May 07 21:39:32 Updated: 1:wpa_supplicant-1.1-1.fc18.x86_64
May 25 15:33:44 Installed: kernel-3.9.3-201.fc18.x86_64
May 27 08:06:42 Updated:
1:NetworkManager-glib-0.9.8.1-3.git20130514.fc18.x86_64
May 27 08:06:47 Updated: 1:NetworkManager-0.9.8.1-3.git20130514.fc18.x86_64
May 27 08:06:53 Updated:
network-manager-applet-0.9.8.1-4.git20130514.fc18.x86_64
Given that this has really started the day before yesterday, I suspect
it has something to do with the NetworkManager update. Is anyone else
having this problem?
(Please -- do not tell me to "dump the evil NetworkManager". I'm trying
to solve a problem here, not make some stand against the tide. Thanks.)

Well, my target is not to be private with email but only to be secured

qemu-system-x86 eat 400% CPU
by Franta Hanzlík
On Fedora 19/x86_64, Xeon 4cores/8threads, 8GB RAM I have in a VM
installed windows 2000 (full qemu cmdline see below). What is weird,
'top' on host show that all 4 threads load CPU at 100% each. On guest
are running only minimum processes and windows task manager show load
0-2%; virtual machine is almost idle. VM itself seems react well, its
responses are fine.
Please, how is possible debug this issue?

F20 - Unintended consequences of no default MTA - How best to fix
by Robert Moskowitz
An unintended consequence of no default MTA in f20 is no local deliver
of system mail. It IS possible to just ignore (or leave it to the logs)
stuff going on in a desktop system, but services like logwatch are very
helpful to maintain a healthy system. Plus there is cron for regular
tasks we like to perform.
So no MTA seems good IF we can configure mailx to do the local
deliveries. I am kind of assuming that some changes to /etc/mail.rc
might do part of the job. Probably some /bin/sendmail script that maps
sendmail arguments to a mailx call. Plus if you DO install sendmail or
postfix, it should undo this setup.
I suppose I should submit a bug report on this as the best way to get
the developer's attention.
But does anyone have any good recommendation(s) on how to do this? I
kind of like no MTA on resource straped systems, but we need to address
local delivery.

f20 - gedit
by Robert Moskowitz
Well here comes the questions on 'where is it now'. Of course since I
skipped f18 & f19, these may be 'old' issues....
So with gedit, where 'preferences'? I need to turn off line wrap so I
can use it to edit various config files. Meanwhile, back to vi.

Different actions on different passwords?
by William Oliver
I guess this is more of a general linux question than a fedora one, but since I use fedora...
A friend of mine (a Windows afficionado, but not experienced with linux), and I were talking about recent examples where folk were required by the court to provide the password for their laptop. That lead to a beer-induced thought problem:
In linux, is it possible to dictate two different actions upon login with different passwords? For instance, given an encrypted file dat.txt, could one have a login such that:
login: billo
Password: Password1
Action: bring up shell
login: billo
Password: Password2
Action: delete dat.txt, then bring up shell
Assume some arbitrary level of encryption. I guess with just file encryption (e.g. dat.gpg) it's not a loging problem. So assume there's encryption of the home directory or of the /home partition.
I couldn't think of any. There are a thousand ways to delete a file on login, of course, but I couldn't think of a way to accept two different passwords. The closest I could come up with was to have two different accounts with the same userid but different usernames in /etc/password, with a different initial startup for each. But that would provide two different usernames...

Fedup Failure
by Mark Bidewell
I tried upgrading from Fedora 19 to 20. When the System Upgrade task
starts I get a failure around /run/initramfs (it moves fast). Then it
boots back to Fedora 19. Any thoughts on how to debug?
