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?

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.
Open source is the future. It sets us free.
I tried it. It was not easy to figure out how to use anaconda gui to setup
install into a subvolume - but I got it done. I now have 3 subvolumes:
sudo btrfs subvolume list /
[sudo] password for nbecker:
ID 256 gen 1818627 top level 5 path home
ID 259 gen 1818478 top level 5 path root
ID 487 gen 1818625 top level 5 path root00
But if I try to boot with 1st grub entry, I get:
dracut-initqueue warning could not boot
starting dracut emergency shell
If I try to boot off the grub entry labeled 'rescue', it boots OK.
dracut says something about fixing initramfs.
Those who fail to understand recursion are doomed to repeat it
I am just learning about btrfs on my home system.
How do I know what kind of options where used to create a BTRFS filesystem?
I installed F21 from scratch and I created a BTRFS filesystem on a HDD.
I think I created it with the "single" option.
Now I read that that is dangerous, I should have created it as one of the
raids if I want to have data redundancy and protection vs bit rot (which is
what I was looking forward to).
How can I verify it? Also, If I want to change it, can I do it IN-PLACE or
do I have to reformat/recreate the filesystem?
Thanks for whatever help/illumination you might provide. I am catching up
on btrfs, but I am not there yet.

There's regularly questions here, and around the internet (ie ask.fp.o)
about dual booting Fedora with Windows systems, or other Linux systems,
or OSX. To address the more common questions, the Fedora Docs team has
written a Multiboot Guide.
The guide is intended to help set up a multiboot system in a functional
way, or to help get to a more functional state if needed. For the most
part, we've tried not to make it intimidatingly complex, and I hope that
it will aid you in most multibooting situations.
As with all of Fedora's documentation, feedback from readers is crucial
to ensuring the quality of the work. Please use the guide, and if you
find questions unanswered or answers unclear, reply here or use the
'multiboot-guide' component of the Fedora Documentation product on

I have finally reached a stage where I may have to bite the bullet,
grasp the nettle, screw my courage to the sticking place .... and
upgrade my Fedora version.
I am currently running Fedora 17. Which is of course antediluvian. But
everything I have seen on this list with respect to upgrading terrifies
me. Disasters seem to lurk everywhere and I haven't the skills to cope
with disasters. Nor do I have access to any support in respect of Fedora.
So, if you will bear with me, I'd like to start off with a preliminary
The seeming necessity for upgrading arises from a pressing need to
upgrade "R" to version 3.2.0. When I try to build this version I get a
load of error messages (basically coming from gcc I think) like unto:
> connections.o: In function `gzcon_write':
> /home/rolf/Desktop/Rinst/R-3.2.0/src/main/connections.c:5469: undefined reference to `deflate'
There were also complaints about undefined references to inflate, crc32,
deflateEnd, inflateEnd, inflateReset, inflateInit2_, deflateInit2_,
compress, uncompress, and zlibVersion, many of which were issued
repeatedly. It finally gave up, saying:
> collect2: error: ld returned 1 exit status
People from the R-help mailing list said that the problem lies in some
"compression related" libs --- zlib, bzlib, liblzma.
I tried installing zlib and zlib-devel (using yum install) and was told
in both cases that my system was up-to-date. I tried installing bzlib
and was told there was nothing by that name. I then installed lzma and
lzma-devel (*that* seemed to work) but it didn't help. Same undefined
references problems as before.
It was also suggested that I try building R-patched. So I tried; no
help there either.
So: Can anyone suggest what I can or should do to overcome this problem
*without* having to upgrade?
Given that the answer to my preliminary question is "No", can anyone be
so kind as to provide me with a *recipe* for upgrading, expressed in
simple-minded terms that I can understand? Something of the form:
(1) First, do this.
(2) Second, do something else.
(3) Third .....
You get the idea. I'm afraid vague generalities would be of no help to
me, since I am a bear of very little brain and long words bother me.
(I know that step (0) is to make a backup of all my user files. Which I
know how to do and will do.)
A specific question, I guess, is: Do I use yum for such an upgrade?
(And if so, what is the syntax?) Or do I use fedup? (And likewise, what
is the syntax?)
If no-one wants to write out a set of instructions for me (and
admittedly I can see that they may well not want to) can someone point
me at such a set of instructions somewhere on the web? Again, they
would have to be expressed in a very simple-minded way. ("Upgrading
Fedora for Dummies".)
Everlastingly grateful for any help that anyone can extend.
