With the SystemRescueCd I backed up the /dev/sda6 partition in /mnt/backup/ naming "diskimage"
After backing up operation the file has the automatic extension like "diskimage.000".
Is this file ok to restore?
If I name it "diskimage.gz" then it is automatically renamed with this extension "diskimage.gz.000"
But here below
the file is name like this:
Do I have to name with the .pimg extension during backup to restore correctly?
And how can I restore it?
I am planning on running a Virtual Private Network from my Fedora
firewall out to a UML virtual colo (running RH9) at another site.
That site will be the place I present services to the world;
httpd, ssh, sftp, smtp. This is to comply with the "no servers"
and dynamic ip restrictions on my Comcast connection to the net;
if my firewall always drives an outbound connection to the
colocation site, I am not worried about changes of ip address,
and I am not opening any inbound ports.
There are a number of options for the VPN - the most attractive
are cipe ( http://sites.inka.de/sites/bigred/devel/cipe.html )
and FreeSwan ( http://www.freeswan.org/ ), though I am told that
one can do all this through an ssh tunnel. I would rather have
simple and secure than super-duper; I have plenty of bandwidth,
and will send outbound http and smtp from the firewall, so the
main bandwidth user will be incoming spam/b/b/b/b mail.
Anyone have some experiences to share about setting up VPN? Is
there anything about either cipe or FreeSwan that is likely to
break with FC1 or FC2?

Because Anaconda doesn't support my usual partitioning scheme (root on Btrfs in LVM in LUKS in LVM in GPT, /boot on Btrfs, etc.), I created the entire layout manually and tried to install Fedora using dnf. The same layout works perfectly fine in ArchLinux.
I basically followed this howto, with adjustments for s/yum/dnf/ and for EFI/GPT: http://dustymabe.com/2014/05/29/manual-linux-installs-with-funky-storage-...
The initial filesystem installation (dnf install -y --releasever=23 --installroot=/mnt/sysimage filesystem) already got a few glitches of this form:
Non-fatal POSTIN scriptlet failure in rpm package filesystem
This^^^ happened to roughly half of the installed packages. I tried to proceed with the rest (i.e., to install @core @standard kernel grub2 grub2-efi sihm grub2-tools), but it failed with scriptlet errors that prevented a few key packages from getting installed at all:
error: %prein(selinux-policy-targeted-3.13.1-157.fc23.noarch) scriptlet failed, exit status 126
Error in PREIN scriptlet in rpm package selinux-policy-targeted
Packages with those errors are reported as failed after the verify step. What I tried next:
* setenforce 0
* upgrading the installation environment and/or the sysimage with dnf and rpm from rawhide
* --releasever=22 instead of 23
* ...and checking for a few other common points with this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1270663
* a plain sysimage directory with no predefined Btrfs subvolumes in it
* unmounting, remounting, checking that everything has seclabel on, no weirdness in dmesg, etc.
Well, nothing of the above helped; the error is still the same.
How can I diagnose this? Where can I dig out the exact reason why the scriptlets are failing?
Provided that Anaconda actually does some steps that I'm missing and can carry out the installation correctly, is there a way to *force* it to just accept whatever is mounted into /mnt/sysimage at the moment, without trying to make sense of it? I'm pretty sure dracut can handle my partition layout just fine, so the entire issue here is about getting the basic installation done somehow.
Theoretically I could create a simple-and-stupid layout that Anaconda can handle, proceed with the installation and reshuffle the partitions afterwards, but that's sooo cumbersome that I thought I'd first ask whether someone knows a workaround to the scriptlet problems.
my computer boot only in emergency mode ...
Looking the journalctl (command journalctl -xb), I found (in thejournalctl
) these lines in red color :
ATA2:00: link is slow to respond....
ATA200: SRST failed (erro 16)
That seem indicate that it is a problem to access the HDs..
I found a possible solution to the problem in this post:
There is wrote that :...the problem can depend by the physic set up of the
HD (as "master", "slave", "single drive", ...): this set up can be done by
changing the position of a jumper on the HD...
I know that, in the past time, the HDs had to be set physically in this
way.., but recently I never heart anymore that the modern HD need this
So actually I don't care anymore of the configuration of the HDs
(my HD is Toshiba 1 TB that I bought few mounts ago).
I would like to have a confirmation that what I read in the post is only an
obsolete information and, in any case, I would like to know also what I can
do to go around in my problem..
>From the command line: ls /dev/sd* I get:
give me this input :
/dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sdb /dev/sdb1
I used to use netcat to check if a particular host is up or if I have
internet connection before I run a few scripts. I would use the -z
option in particular. But now I see that has been removed:
$ nc -z imap.gmail.com 993 && sync-my-email.sh
ncat: invalid option -- 'z'
Here is the excerpt from the old manual page:
-z Specifies that nc should just scan for listening daemons, without
sending any data to them. It is an error to use this option in
conjunction with the -l option.
Any ideas what happened to it? What can I use as replacement?
Thanks for any ideas.

I replied to Marco and thought that I automagically replied to the list. I got it to work by manually changing the data with the dates:
Test Opponents Grulla Opponents
2015/01/03-Edinburg-Vela 0 10
2015/01/06-Zapata 1 0
2015/01/13-Lyford 2 0
2015/01/16-Roma 0 0
2015/01/20-Mercedes 0 3
2015/01/23-Laredo-Nixon 1 2
2015/02/03-Zapata 8 1
2015/02/10-Hidalgo 1 9
2015/02/13-Raymondville 3 1
2015/02/17-Monte-Alto 1 0
2015/02/20-Zapata 0 0
2015/02/26-Hidalgo 0 4
2015/03/06-Raymondville 2 2
2015/03/17-Monte-Alto 6 1
2015/03/26-Port-Isabel 3 0
2015/04/03-Rockport-Fulton 0 7
then modified 2015gfga.plt and added a range
set yrange [0:10]
will fix the graph to what I would like
[olivares@localhost tmp]$ cat 2015gfga.plt
#set terminal postscript eps color solid
set border linewidth 1.5
set style histogram errorbars linewidth 1.5
set style data histograms
set style fill solid 1 border -1

#set xdata time

set ytics 1 nomirror
set key top left
#Start of user script
ExtData1 = '2015gfga.dat'
plot '2015gfga.dat' using 3:2:xtic(1) title col lc rgb '#084594', '2015gfga.dat' using 2:3:xtic(1) title col lc rgb '#f6e8c3'
I had in the last line
plot 'ExtData1' using 3:2:xtic(1) title col lc rgb '#084594', '' using 2:3:xtic(1) title col lc rgb '#f6e8c3'
and gnuplot was reporting an error. I modified it to above and removed ExtData1 reference and it worked.
I tried to set the xtics manually and change them according to Marco's reference, but the graph did not refect all the games so I modified the data file and added the date and the opponent and then modified the range to prohibit the line going below and keep everything in quadrant I. If anyone has a nicer way to make the graph look better, or format it using something else please help. I would like for our athletes to see what we need to work on the Goal Differential and not allow too many goals against us.

I have a brand-new Dell Precision workstation, on which I'm trying to
install Fedora 23 (with my preferred desktop environment, MATE), which
is turning into the most frustrating Linux install I've experienced in a
long time (and I've been using Linux since before Red Hat existed).
I started with Fedora-Workstation-netinst-x86_64-23 on a thumb drive. I
booted, selected automatic partitioning and MATE, and it started
downloading RPMs. When it finished downloading, it rebooted.
Apparently, there's a conflict between release and updates on who owns
/etc/xdg/menus/mate-preferences-categoris.menu, and anaconda just
crashes and reboots (not even a traceback) on an install transaction
After a few passes through that before I figured out anaconda was not
going to install MATE (with frustrating waits for downloads each time),
I gave up and did a minimal install. Then I did a dnf groupinstall
MATE, and that downloaded all the RPMs, then gave me the error about the
file conflict. I tried to exclude one of the choices, use --best, etc.,
and nothing would solve it.
Also, when "dnf groupinstall foo" is run, even if it fails, dnf then
thinks the group is installed (and so a repeated groupinstall does
nothing). I had to do a groupremove first.
I just manually installed the RPMs from the dnf cache to get around the
MATE brokenness, and then got systemd to do a graphical boot.
Now, when I get to the graphical login, my USB is dead. I can boot
single-user mode and the keyboard works fine; as soon as the graphical
login loads, USB appears dead (keyabord is like it is powered off, no
Numlock, Capslock, etc.). Tried unplugging keyboard, moving it to
different USB ports (directly on the computer instead of hub), etc. with
no result. The fact that the keyboard works in single-user mode shows
there's no hardware problem, Linux USB issue, etc.
At this point, I guess I'll roll back and try Fedora 22. If I ever get
a working desktop, I'll try to file some bugs I guess. I found a BZ
about anaconda that appears to match my problem (1287841). That doesn't
explain the MATE conflicts in the repos, dnf groupinstall fail, or
disappearing USB though.
