SSHD keys
by Robert Moskowitz
If I want to 'reset' SSHD to have all new keys do I stop it, delete the
files:
/etc/ssh/ssh_h*
and restart it? This seems to be working...
And does the server keep client sigs anywhere? I can't find any file
that looks like it would be housing such...
thanks for your help!

Error with xz
by Robert Moskowitz
First I dd an SD card:
sudo dd if=/dev/sdb of=/home/rgm/arm/rsel-minimal.img bs=4096
conv=notrunc,noerror
Then I ran xz which produced an error:
xz -k rsel-minimal.img
xz: rsel-minimal.img.xz: Cannot set the file group: Operation not permitted
Is this because the sudo made the owner of .img root? Do I ignore the
error or go back and change the owner of .img?
I will want to make this .img available to others to download and build
their own SDcards for booting on Cubieboards.

FC 20 and new skype?
by Paul Erickson
Has anyone succeeded in installing that "latest" version of SKYPE in
FC20? It was nice to have it working for a while, but MicroSoft seems
to have done a good job of breaking things.

gdm failed to auto mount ecryptfs
by Pal, Laszlo
Hi,
After upgrading to gdm 3.12 (it was a mistake for several reasons :)) I've
fixed almost every problem except one.
When I log in using gdm my home which is on ecryptfs cannot be mounted
automatically
I need to log-on using console and after that I can use graphical
environment
I think my pam files contains the entries needed
gdm-password:auth optional pam_ecryptfs.so unwrap
postlogin:auth optional pam_ecryptfs.so unwrap
postlogin:password optional pam_ecryptfs.so unwrap
postlogin:session optional pam_ecryptfs.so unwrap
postlogin-ac:auth optional pam_ecryptfs.so unwrap

Any idea how can I fix it?
Thanks

Suddenly keeps asking for Wifi key
by Oliver Ruebenacker
Hello,
For months or years, I was able to connect to my home Wifi without
re-entering the key. Until some updates two days ago, which, I think,
included NetworkManager. Now, whenever I boot first time during the day, it
asks me for the Wifi key.
I should mention that months ago, there was this KWallet thing which
asked me for a password every time I wanted to connect, which was an
enormous pain, and I somehow managed to disable it, and I was fine since,
until now.
I absolutely want to be able to connect to my Wifi without entering a
password or network key every time.
Thanks!
Best,
Oliver

cloned sd card is not booting
by Robert Moskowitz
This is a Fedora arm problem, but probably more experience with dd and
sd cards here...
SO I boot my Cubieboard2 from microSD. I grabbed 8 16GB cards from the
bin at the MicroCenter checkout counter. They work fine for building
F21 arm boots, but I am getting far enough into the process that if I do
something wrong, I don't want to go all the way back to the beginning.
I rather clone the card, play around, and soforth. So I tried using:
sudo dd if=/dev/sdb of=/dev/sdc bs=4096 conv=notrunc,noerror; sync
the target sd card has been previously use. The copy fails in use as
follows:

=======================================================
I put the card back in my build system and looked at it with Gparted
which shows the whole drive as unallocated, even though the system
successfully mounted /boot (but not /).
So the question is: HOw better can I clone the card? SDFormatter in
Windows is one suggestion, but I don't want to have to jump over to the
family XP system.

how to disable tmpfs
by Dennis Kaptain
While lurking on the list, I learned in a thread "Cannot make a copy
of video DVD with k3b" that the way fedora is configured, tmpfs will
consume 50% of my RAM and mount itself in /tmp. If you have gobs of
RAM I suppose you'd never miss it unless you are doing serious video
editing or something like that.
My system has only 3GB of RAM and it does appear that 1.5GB is now a
tmpfs. I really don't have that to spare. I do have a 5GB /tmp
partition on a physical HDD that I thought I had been using for years.
Only now did I learn that I'm not.
Rick Stevens suggested "systemctl mask tmp.mount" as a fix. I tried
that and then I couldn't log in. It turns out, that command will make
my / partition read only. I googled it and discovered that someone
else had the same problem. There was no answer to that thread. You can
fix this by "mount -o remount,rw /" and then issuing "systemctl unmask
tmp.mount" and rebooting again.
I tried editing the entry in /etc/fstab from
UUID=996d5f64-0745-4af7-9260-559d5c66c7bd / ext4 defaults 1 1
to
UUID=996d5f64-0745-4af7-9260-559d5c66c7bd / ext4 defaults,rw 1 1
but that still didn't mount / rw.
So, how do I turn off fedora's tmpfs forever so I can use my physical
/tmp partition and not consume all my valuable RAM? Or stated
otherwise, how do I disable tmpfs AND keep / read-write?
Thanks,

running a specified binary across reboots
by Kevin Wilson
Hello, Fedora users,
I want to run a binary of some Fedora application I wrote immediately
after reboot.
I know that as a workaround I can wrap it as a systemd daemon, but I
prefer not to.
In previous fedora distros, making it run across reboots was enabled
by adding an entry
in /etc/rc.local.
What is a good practice to achieve it in Fedora 20 ? there is no
/etc/rc.local in my fedora 20, and trying to add an entry in
/etc/rc.local does not cause it be be run across boots.
regards,
Kevin

Strange parted behaviour
by Robert Moskowitz
So I am making progress but saw a strange bit.
#parted /dev/sdb mkpart uboot ext3 4 516
# parted /dev/sdb print
Model: Generic- Multi-Card (scsi)
Disk /dev/sdb: 7969MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 4194kB 516MB 512MB fat32 uboot
I formated it with:
#mkfs -t ext3 /dev/sdb1
# parted /dev/sdb print
Model: Generic- Multi-Card (scsi)
Disk /dev/sdb: 7969MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 4194kB 516MB 512MB ext3 uboot
So why did parted mislabel the partition?
