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?

how to correctly log without journald (and its blobs)?
by Franta Hanzlík
In previous Fedora distros was (IMHO) right way to log only to syslog,
without journald and its (for me) unwanted annoying binary logs, by using
configuration as:
*) Set systemd log target to syslog:
systemd.log_target=syslog (syslog-or-kmsg) ---- on kernel cmdline
systemd.default_standard_output=syslog --/
and
LogTarget=syslog ---- in systemd.conf
DefaultStandardOutput=syslog --/
*) configuring rsyslog to listen on /dev/log unix socket:
$SystemLogSocketName /dev/log ------ in rsyslog.conf
$ModLoad imuxsock ----/
$OmitLocalLogging off ---/
$AddUnixListenSocket /run/systemd/journal/syslog --/(legacy directives)
$AddUnixListenSocket /run/systemd/journal/socket -/
$AddUnixListenSocket /run/systemd/journal/stdout /
(not sure when all last three directives needed)
*) prevent to run journald:
systemctl mask systemd-journald.service
(and maybe mask systemd-journal-flush.service)
And it works fine.
But in actual Fedora 24 in systemd man page values syslog-or-kmsg and
syslog are missing in LogTarget option. As systemd/journald man pages
say hardly anything about exact mean of appropriate configuration for
this purpose, then please when someone more knowledgeable can advise:
- where to direct the systemd output? Maybe to kmsg an then read it in
rsyslog via imklog?
(rsyslog should have also imkmsg module, but is not in rsyslog-8.12.0-3.fc24)
- what about /run/log/journal/.../system.journal ?
On my test F24 system it have open rsyslogd, abrt-dump-journal-oops and
abrt-dump-journal-xorg (no need for these last two) processes. Uses it
also something else?
- what about /run/systemd/journal/{dev-log,socket,stdout} unix sockets?
Should rsyslogd listen on them?
- /dev/log seems be now symlink to /run/systemd/journal/dev-log socket
(as defined by systemd-journald-dev-log.socket) Should it be left
(because now something sends to /run/systemd/journal/dev-log), or can
be /run/systemd/journal/dev-log removed?
Thanks in advance for some clarification about this.

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

PC locked, but one screen is showing
by Todor Petkov
Hello,
I have the following situation:
Laptop Lenovo T540p, attached to external monitor LG, and running
Fedora25 with Mate desktop.
After the recent upgrade from 24 to 25, after I press the combination
for screen lock, the current monitor is being locked properly (blue
background with the unlock dialogue). However, the other monitor is
still showing its desktop. For example:
On the external monitor I have a browser window, on the laptop monitor
I have a chat client. The 'active' monitor is the external one (active
means showing the active application). I press the lock keyboard
combination, the external monitor is locked, but the laptop screen
still shows the chat client. I can not click in it, it does not
refresh (showing new messages), but it's still visible. If I press ESC
several times, the "not locked" screen is refreshed and shows the
unlock.
Is this a known issue, can someone reproduce it?
Thanks in advance.

panel locks after upgrade to F25
by Maurizio Marini
Hello
after upgrade to F25, panel locks randomly.
I have KDE and plasma5.
When it happens CTRL+ALT+F2 and back CTRL+ALT+F1 works for me.
I wonder if I can clear something inside .config, something that is recreated
fresh after logoff and login, to fix the issue
or should I ask on ked mlists?
Many thanx in advance

openshot video editor on Fedora
by Samuel Sieb
Is anyone else using openshot on Fedora? I installed it from rpmfusion.
My son has been trying to edit a video and it just keeps crashing when
doing typical actions. I've tried it on computers with F23 and F24 (I
haven't upgraded any computers to F25 yet) and it does the same thing on
both. I can't imagine that this is expected, so is it my computers or
is it something with Fedora? The one crash I looked at in abrt appeared
to involve QT. I'm wondering if anyone else has used it recently
successfully either on Fedora or not.

Shell question
by JD
Reading lines from 2 files in such a way that each iteration
lets me read the next line from each file so that the items
read from each file are in sync as far as line number is concerned.
Is this "doable"?
For a single file, indexing to next line is automatic, visa vis
while read line; do
echo $line
done < some_file.txt
for when more than 1 file is involved, it is not so easy ...
Hypothetical (of course, non-working example):
export index=1
while true do;
file_A_line=`read line$index` # Read from file A
file_B_line=`read line$index` # read from file B
[ x$file_A_line = x -o x$file_B_line = x ] && break
<do something withfile_A_line and file_B_line>
index=`expr $index + 1`
done
So how can the reading from 2 files be accomplished and keep the index
to next line in sync?
I know it is a no brainer with a C program.
Thanx.

How to prevent headless JVM (Fedora 25)?
by JUSTIN TAYLOR
I have a 3rd party app that use a Java GUI, so it won't run on a headless JVM. I had it working until I installed a different app using dnf. It overwrote my JVM with a headless one and now the Java GUI app is broken. Is there a way to install/register a non-headless JVM with Fedora so it won't keep installing the headless JVM?
Thanks
