SATA optical drives
by David Fletcher
I'm currently running FC5, will probably upgrade to F7 in a couple of months.
Unfortunately my CD/DVD rewriter appears to have died, before it's
even seen a dual layer disk :'(
SATA hard drives run without problems for me, but now that SATA
optical drives are starting to appear in the shops, would it be OK to
buy one of these and get rid of another wide ribbon cable?
Is anybody already running them with Fedora?
Thanks for any advice/experiences.

[FC8] ssh and CAC card???
by Todd Denniston
From what I understood, the change to openssh listed in:
rpm -q --changelog openssh |less
as:
"* Wed Jun 20 2007 Tomas Mraz <tmraz(a)redhat.com> - 4.5p1-7
- experimental NSS keys support
- correctly setup context when empty level requested (#234951)
"
was supposed to allow the Common Access Card (CAC) to work with the shipped
Fedora 8 ssh.
As per NSS usual, everything is undocumented, i.e., `ssh-add --help` does not
help at all, and `man ssh-add` points to `ssh-add -s reader`
# ssh-add -s 0
Enter passphrase for smartcard:
SSH_AGENT_FAILURE
Could not add card: 0
# ssh-add -s 1
Enter passphrase for smartcard:
SSH_AGENT_FAILURE
Could not add card: 1
So does anyone know how to use the possible functionality, or are we reduced
to reading the source?

Changing date with procmail
by Michael A. Peters
Anyone know of a procmail recipe to change the date on incoming
messages?
If the date is in the future by more than 24 hours - I'd like to just
change it to the current date.
If the date is in the past by more than two weeks - I'd like to just
change it to the current date.
I'd like to do it in procmail - if someone knows how.
I've done some searching, still have some to do.
Found some stuff on extracting the date, but not on modifying it if
necessary.

Re: Backing up system
by gmspro
Hi,
http://www.sysresccd.org/Download
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
http://www.sysresccd.org/Screenshots
the file is name like this:
"diskimage.pimg"
Do I have to name with the .pimg extension during backup to restore correctly?
And how can I restore it?

VPN options
by Keith Lofstrom
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?

Scriptlet errors during manual installation of Fedora 23
by Andrej Podzimek
Hi,
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.
Cheers,
Andrej

ATA2:00: link is slow to respond....
by Angelo Moreschini
Hi,
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....
(and after..)
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:
http://codeverge.com/opensuse.org.help.install/-solved-ata1-srst-failed-e...
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
operation..
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
/dev/sdb2
Thank you
regards

nc missing option -z
by Suvayu Ali
Hi,
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.
