If you do it as an independent network, separate IP block and no default
route, there's almost no bandwidth being chewed when not in use (just
keep-alives).  That's probably the route I'd go - a system connection so
it's always available (doesn't require user interaction, can work when
user locks themselves out even :) ).

In essence, these solutions are functionally like using a VPN.  The
computer keeps an open connection to a server whenever it can, and that
connection can then be used to allow the server to access the computer.
So you could set up a separate "management" VPN system, like OpenVPN,
that then isolates each client connection (so one user can't access
another user's computer directly across it).  Don't send a default
route, just use an independent RFC1918 (or IPv6 ULA) block from any
other corporate networks.


Yeah, I was looking at things like Nebula for a sort of background VPN 
for systems management, but that looks like overkill.


I may wind up just having a tiny OpenVPN instance in the cloud that 
users can connect to so admins can ssh in or run playbooks over the VPN. 
I was hoping for something less manual, though. With the Windows 
laptops, as soon as folks authenticate to Azure AD, the helpdesk guys 
can just fire up a remote desktop. I'd love something that easy.


I suppose I could set up the laptops so that they log into the VPN at 
boot, that would do the same thing and the staff on the Linux laptops 
wouldn't have to do anything manual. But I don't want to chew up that 
VPN bandwidth if I don't have to.

How can you get remote access to laptops behind a NAT/firewall?

[Thomas Cameron via users]

In my company, we're rolling out Linux laptops to my team. We're 100% 
remote workers, no one even lives in the same state as the headquarters.


If my teammates are logged into the VPN, it's pretty easy to administer 
a team member's laptop - I just ask the user for the IP address and ssh 
in as the service account (with keys, not passwords), or run an Ansible 
playbook against the machine.


For the Windows users (not on my team), our helpdesk uses Quick Assist, 
and IT can remote desktop into anyone who's logged in to the Azure 
Active Directory domain. Even if the person is behind a cable modem 
doing NAT.


So my question is, is there any sort of software which is similar to 
Quick Assist we can install on our Linux laptops so that the Linux team 
sysadmins can get access to laptops? I've seen folks on this list talk 
about TeamViewer and AnyDesk, but both of those seem to be paid 
solutions. Is there any sort of F/OSS solution? I am totally OK with 
hosting a cloud instance as an authentication server or something like 
that. I also heard something about Chrome Remote Desktop. Apparently 
Google does session brokering, so that may be interesting, although 
we're not a Google shop, we're a Microsoft shop and I'm bringing Linux 
in. I'd much prefer a F/OSS solution, if anyone has any advice.


Thanks for any advice!

Of course you could take a completely different tack and use

I qemu-img to a raw and then back to a qcows2.

Dump and restore only interact with used blocks.  So if there is old 
data in unused blocks in the original disk, the dump won't save those 
and the restore won't put them back.


That explains why the check sums are different,
but the restored files work.   Thank you!

You can't dump a qcow file because the blocks are not in order and there 
is extra metadata.  You can only dump from something that looks like a 
raw partition.  You might be able to use something like nbd to create a 
device from a qcow that looks raw.


I am switching to ".raw" files.  They seems to come
back working

Re: How do you unsparsify a qcows2 file?

[Bill Cunningham]

You might want to think about setting a size on that file. dd can be 
pretty destructive as well as useful. I like to randomize file with it 
before truncating the contents. For example, if a file is 4096 bytes, I 
would use, 'dd if=/dev/zero of=/file bs=4096 count=1 conv=notrunc. Just 
so there is no truncation of the file. dd isn't to be played with 
haphazardly. Good luck.

Yep, that's how I always sparsified my files before the virt-sparsify
tool existed. Write zeroes till you run out of space (thus making all
the free space on the disk blocks of zeroes), shut down the VM, and
qemu-img convert from qcow2 to qcow2. The destination file is much
smaller (usually) but has the same data in it. Rename the file and
now the VM takes less space.

Seems like that would work. Might need to do it as root in case the
kernel doesn't allow an ordinary user to use up all the free space on
a disk. And don't forget "rm /sometempfile" once the dd finishes
with out of space errors.

Of course you could take a completely different tack and use
qemu-img convert to change the qcow2 format file to a raw
disk image and modify the virtual machine to use that new file.


I wonder if qemu-ing convert will convert from
qcows2 to qcows2?  I will see!

Thank you for the help!

Boot up the virtual machine and write zeroes to a temp file on that disk
till you get out of space errors is one way. Basically stop after the

Of course. It's not my default, so when the GRUB2 menu appears I have
to arrow down to the 4th entry to boot into Windows.

What's really nice about this setup is that when default booted into
Fedora 32 I can mount the /dev/nvme0n1p3 Windows partition r/w.

I have Intel RST "fake RAID" on my Lenovo ThinkPad P72. As delivered, 
Windows 10 Pro was installed on two 2TB NVMe SSDs in a RAID1 mirror 
configuration. While I could have also installed a standard notebook 
SATA SSD, I postponed that idea (see below) and broke the RAID1 mirror 
instead. The BIOS Storage setting gave me two options: RST or AHCI. The 
BIOS is wrong. It should say RST or NVMe. SATA or AHCI are not options. 
And boy are the two raw NVMe drives F-A-S-T 


I went through all the hand wringing and fear of screwing up something I

think of from Windows 10, and a went to the trouble of getting a Lenovo

Happily, once I broke the RAID1 mirror, I was able to boot to a Fedora 
live ISO on a thumb drive. It could see both /dev/nvme0 and /dev/nvme1 
SSDs. The #0 device still contained one half of the mirrored Windows 10 
installation. fdisk shows the following detail:

This frees /dev/nvme1n1 for a normal installation from a live CD image.

As I indicated above, I later installed a 4TB SATA internal drive in an 
expansion space inside the P72. I had to buy a wiring adapter to connect 
the SATA drive to the P72's internal chassis wiring. That wiring doesn't 
come instsalled from the factory. I got the kit from EggHead.


Hope this helps.

I have Intel RST "fake RAID" on my Lenovo ThinkPad P72. As delivered,
Windows 10 Pro was installed on two 2TB NVMe SSDs in a RAID1 mirror
configuration. While I could have also installed a standard notebook
SATA SSD, I postponed that idea (see below) and broke the RAID1 mirror
instead. The BIOS Storage setting gave me two options:  RST or AHCI.
The BIOS is wrong. It should say RST or NVMe. SATA or AHCI are not
options. And boy are the two raw NVMe drives F-A-S-T 

I went through all the hand wringing and fear of screwing up something
I didn't completely understand at the time. I backed up everything I
could think of from Windows 10, and a went to the trouble of getting a
Lenovo ThinkPad Windows restoration thumb drive.

Happily, once I broke the RAID1 mirror, I was able to boot to a Fedora
live ISO on a thumb drive. It could see both /dev/nvme0 and /dev/nvme1
SSDs. The #0 device still contained one half of the mirrored Windows 10
installation. fdisk shows the following detail:

As I indicated above, I later installed a 4TB SATA internal drive in an
expansion space inside the P72. I had to buy a wiring adapter to
connect the SATA drive to the P72's internal chassis wiring. That
wiring doesn't come instsalled from the factory. I got the kit from
EggHead. 

Hope this helps.

No.  RST is unsafe by design, and the kernel developers won't support it.

 * No NVMe device power management
 * No NVMe reset support
 * No NVMe quirks based on PCI ID
 * No SR-IOV VFs
 * Reduced performance through a shared, legacy interrupt

I thought RST was where it used a small SSD as caching for a regular 
spinning hard drive.  The few times I've had to deal with that, I just 
broke the RAID and let Windows use the hard drive directly.


BIOS allows me to choose AHCI or RST. I must use AHCI to boot the FC31 
drive, and RST to boot the Windows drive. Neither will boot with the 
other.  Sigh.

I thought there was some sort of support for that, but it's hard to find.

Check if there's an option in the BIOS to disable the RAID.

Well, I think they want you to add it to the "Wishlist" 
https://rpmfusion.org/Wishlist as
I've previously mentioned.  If you too the time to go to that page you'd see

"Use this page to post a request for a packages that can't go to Fedora but 
would be nice
to have in the RPM Fusion repository"

But, of course, editing it may be an issue if you don't have a valid login.  
And, that is
one of the questions you've previously raised and for which I've asked about on 
the user's
list.  If you've signed up, you'd see that in the archives.

Just like Fedora, I prefer not to use the HyperKitty web interface.

Hi,

To "reset" SELinux on your system please remove all "non-system" modules:

# semodule -lfull | grep -v 100  # this gives you list of non system
SELinux modules
# semodule -r  # this will remove it

Then there is semanage command:

# cat reset_selinux.txt
boolean -D
login -D
interface -D
user -D
port -D
node -D
fcontext -D
module -D

# semanage import -f reset_selinux.txt
#

# restorecon -Rv /

This will remove all local SELinux modules and reset your local
modifications.

Lukas.

I thought I had seen something to list changed modules, but now I think 
I misunderstood.  I think the easiest way would be to find a clean

It will relabel files back to their "default" selinux context.  However, if you 
added
your own policy or made changes to existing policies I believe they will remain.

You might need some sort of preamp between the guitar and the usb device,

 Yes, audacity should work for basic recording (assuming that when Greg
 says but was not able to get any software that that was on my F22
 machine to recognize the the live feed he just means he couldn't find
 software to do it, not that the USB capture device isn't working).

 For more complicated work a DAW like Ardour (available in the repos)
 will let you record different layers and samples, but you'll have to
 use Jack. That will also let you do things like add effects and other
 stuff like drum machines (e.g. Hydrogen). You may want to check out
 these which I wrote a while back:

 I have seen ads for a setup that will record vinyl records from a

 onto a PC thru a gizmo plugged into the USB port. If you were to find any
 of the software that works with this, it may work with your guitar also.
 You might need some sort of preamp between the guitar and the usb device,
 but if it wants to work, you should hear _something_.

 How about Audacity? I've used it to record voice announcements. It may look
 like overkill at first but you can do a lot with it, it's an audio editor.


Yes, audacity should work for basic recording (assuming that when Greg
says but was not able to get any software that that was on my F22
machine to recognize the the live feed he just means he couldn't find
software to do it, not that the USB capture device isn't working).

For more complicated work a DAW like Ardour (available in the repos)
will let you record different layers and samples, but you'll have to
use Jack. That will also let you do things like add effects and other
stuff like drum machines (e.g. Hydrogen). You may want to check out
these which I wrote a while back:

How do you store a Live Feed from a guitar

[Gregory P. Ennis]

Everyone,

I finally have enough time to play with my computer and guitar at the
same time.  Does anyone have a method of storing a live feed from a
guitar.  I have a guitar with an acoustic pickup that I normally use
with a regular amplifier.  I now have a usb audio cable from Alesis
LineLink that I can use to connect my Fedora 22 machine to the acoustic
pick up of the guitar.  

I connected the usb audio cable to the computer and to my guitar, but
was not able to get any software that that was on my F22 machine to
recognize the the live feed.

Have any of you used this kind of equipment or other kinds of equipment
to store a live feed from a guitar acoustic pickup.  I would like to be
able to play and store a song or two and then experiment with mixing
the sounds.

Any suggestions

Greg Ennis

F21: How do you turn on syntax highlighting in vim?

[Max Pyziur]

Greetings,

After installing F21, I no longer seem to be able to control 
syntax-highlighting.


I have the same 4 packages installed that I had on F18:
vim-common-7.4.475-2.fc21.x86_64
vim-enhanced-7.4.475-2.fc21.x86_64
vim-filesystem-7.4.475-2.fc21.x86_64
vim-minimal-7.4.475-2.fc21.x86_64

...

I also use the command:
:set syntax=on

and

:syntax on

with no results.

Thanks.

I removed vim-gtk-syntax-20130716-3.fc21.noarch, started a terminal 
session, checked a script, and the highlighting was on.


Don't get it.

[389-users] bak2db script: how do you use it?

[Graham Leggett]

Hi all,

I am now trying to make the initial replication happen manually through the 
restoration of a backup. This is also turning out to be strangely difficult.

After backing up servera I have the following directory on serverc:

[root@serverc ~]# ls -al /tmp/replicate/
total 16
drwx--. 4 nobody nobody 4096 May  5 12:08 .
drwxrwxrwt. 6 root   root   4096 May  5 13:30 ..
drwx--. 2 nobody nobody 4096 May  5 12:08 NetscapeRoot
drwx--. 2 nobody nobody 4096 May  5 12:08 userRoot

I want to restore the contents of userRoot to serverc, which looks like this:

[root@serverc ~]# ls -al /var/lib/dirsrv/slapd-serverc/db/
total 20604
drwxrwx---. 3 nobody nobody 4096 May  5 13:31 .
drwxrwx---. 5 nobody nobody 4096 May  5 13:30 ..

-rw---. 1 nobody nobody 10485760 May  5 13:31 log.01
drwx--. 2 nobody nobody 4096 May  5 13:30 userRoot

I try and import the backup like so:

[root@serverc ~]# /usr/lib64/dirsrv/slapd-serverc/bak2db /tmp/replicate/ -n 
userRoot
[05/May/2014:13:49:53 +0200] 389-Directory/1.2.11.15 - debug level: backend 
(524288)
[05/May/2014:13:49:53 +0200] - Warning: Unable to read dbversion file in 
/tmp/replicate
[05/May/2014:13:49:53 +0200] - Restore: backup directory /tmp/replicate does 
not contain a complete backup
[05/May/2014:13:49:53 +0200] - archive2db: Failed to read backup file set. 
Either the directory specified doesn't exist, or it exists but doesn't contain 
a valid backup set, or file permissions prevent the server reading the backup 
set.  error=53 (Invalid request descriptor)

No luck. Let's guess again:

[root@serverc ~]# /usr/lib64/dirsrv/slapd-serverc/bak2db 
/tmp/replicate/userRoot/ -n userRoot

Lots of encouraging looking output, but the server is now completely empty - 
the root DSE is gone.

Looking at serverc, we see the userRoot directory has been ignored and we now 
have a totally different directory structure:

[root@joey ~]# ls -al /var/lib/dirsrv/slapd-joey/db/
total 260252

I don't want to maintain multiple lists of the same contacts so I too
have been maintaining them in Google even though I had them all in LDAP.
Obviously I want the abstraction so that I can access from all software
on all machines/devices.

LDAP has the added bonus of shared contacts if there is more than one
user that needs access but of course Google Apps for Businesses solves
that issue but now for a cost.

I keep my contacts in 389 DS (LDAP), with EGroupware as a frontend.  I access 
them in KDE via Akonadi's DAV Groupware Resource which has an option for 
EGroupware.

This way, I can get them via LDAP, GroupDAV, and sync with Android using 
CardDAV-sync (http://www.dmfs.org/carddav/), which is available in the Play 
Store.

 But what do people running Fedora/KDE usually do?

I have the feeling of late that I am often doing things that people running 
Fedora/KDE aren't usually doing, so I'm disqualifying myself from commenting 
on this. ;)

Speaking only for myself, I just keep everything in Google Contacts (I
also have an Android phone).

Cue flame-war about evil intentions of Google, etc. ...


While this is a KDE-oriented question my experience may be useful to this 
discussion; my method is to use one Desktop as 
having all PIM data: contacts, calendar, memos, todos. For this I use 
Evolution.


In order to sync it with my Android phone, I use different cloud services, 
with the exception of Google.


The services that I have tried are: Funambol(actually onemediahub.com), 
MemoToo, and Everdroid. Each has its peculiarities and advantages; Memotoo 
is the one that I prefer currently. Everdroid has an advantage of syncing 
text messages (easier to review them in bulk on a webpage than on a 
phone).


In order to sync from the Desktop to the cloud I use syncevolution's gui.

On the Android phone, there are Apps tied to the particular services. On 
the phone, I've deleted the contents of the local phonebook, and just use 
the Memotoo one. Memotoo has the capability to delete its current contents 
and overwrite it with the contents of the server. That way any duplication 
is avoided.


Memotoo charges a fee (~$1.50/month, I think); more nuisance than anything 
else.


The syncevolution email list is very helpful in sorting out issues.

I, too, keep all my contacts in Google Contacts. They sync to
Thunderbird via the Google Contacts extension, sync to my iPhone, iPad,
and Mac.

abrt: how can you change bugzilla credentials?

[D. Hugh Redelmeier]

On Fedora 17, I'm getting a few aborts.  Before I get to the fundamental 
problem, I'd like to let abrt file a BZ.

The problem is that I mistyped the password when abrt first ran.  Now it 
always uses that wrong password.  So it can never succeed.

Does anyone know how to change abrt's idea of Bugzilla credentials?

Does anyone know where it squirrels awy the Bugzilla credentials?

See https://bugzilla.redhat.com/show_bug.cgi?id=861899

I've looked in /etc/libreport/plugins/bugzilla.conf and in /etc/abrt.
It's not there.

Ah, thanks.  I had tried that menu but didn't know what to do there.
With your encouragement, I pressed on and succeeded:


Edit: Preferences gets you an Even Configuration window.

In that window, you need to select Bugzilla: report to Bugzilla bug
tracker and click on Configure Event.

Then you get a window where you can adjust credentails.--

/etc/rc.d/rc.local is supposed to be executable and exit with return code 0.

systemd will execute it via its /lib/systemd/system/rc-local.service

So now the (general) problem is: What is the proper, current way to

starts, as the last script otherwise? The online documentation is
surprisingly lacking on this.

if you look in systemctl list-unis you find
prefdm.service loaded active running  Display Manager

so make a one-shot service with the right dependency and enable it
with systemctl enable yourservice.service 

/etc/systemd/system/yourservice.service
[Unit]
Description=yourservice
Before=prefdm.service
[Service]
Type=oneshot
ExecStart=/path/to/our/script.sh
[Install]

Harald,

thanks for the quick answer. Just to be sure I understood everything:

1) is a syntax like this (normal shell script) OK for script.sh or is
   there any special rule in these cases? Is exit OK at the end?

#
#! /bin/bash
modprobe radeon
echo IGD  /sys/kernel/debug/vgaswitcheroo/switch
echo OFF  /sys/kernel/debug/vgaswitcheroo/switch
exit
#

2) shouldn't I put yourservice.service in
   /etc/systemd/system/multi-user.target.wants instead?

3) in /etc/systemd and its subfolders there is no file called
   prefdm.service. Is this OK?

4) where is all this documented anyway?

thanks,
Marco

You could use resource limits and/or simple paged results

How do you get FC13 to export using NFS3?

[Bill Davidsen]

There seems to be a great deal of effort in today's FC13/rawhide release to 
make 
sure NFS3 can't be served. First, opening NFS server in the firewall rules 
doesn't open port 111 (sunrpc) so the connect can be built. Then after opening 
that port manually the firewall RELATED rule no longer considers a port handed 
out in reply to a GETPORT request to be related, and that port gets an 
administratively prohibited ICMP reply.

NFS4 is all wonderful, but it isn't what the clients speak. Is there an option, 
method, script, something to make it work without poking great holes in the 
firewall?

[389-users] Multiple LDAP servers - how do you load balance?

[Sean Carolan]

For those of you with multiple servers that use replication, how do
you do your load balancing and failover?  DNS round robin?  Some kind
of hardware load balancer like a Netscaler or BigIP F5?
