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?

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.

F21: Thunderbird insists on calling Fedora list messages junk!
by William Mattison
Good afternoon,
Most messages received from this fedora list are labelled junk by
Thunderbird. This is even though I whitelisted "From" =
"users-request(a)lists.fedoraproject.org". Actually, I have this problem
both in my Fedora-21 and my windows-7 systems. Any ideas? Surely
messages from this list are not junk!
thanks,
Bill.

smartd errors
by Paolo Galtieri
Folks,
recently I have started seeing these messages in /var/log/messages
Oct 27 10:26:13 jackstraw smartd[1177]: Device: /dev/sde [SAT], 16
Currently unreadable (pending) sectors
Oct 27 10:26:13 jackstraw smartd[1177]: Device: /dev/sde [SAT], 16
Offline uncorrectable sectors
which are mounted as follows
/dev/sde1 on /media/NSM/NSM-SENSOR-1 type ext4
(rw,nosuid,nodev,noexec,noatime,seclabel,data=ordered)
/dev/sde2 on /media/NSM/NSM-SENSOR-2 type ext4
(rw,nosuid,nodev,noexec,noatime,seclabel,data=ordered)
I have unmounted the filesystems and run fsck on them and fsck reports
no errors.
[pgaltieri@jackstraw ~]$ sudo fsck /dev/sde2
fsck from util-linux 2.26.2
e2fsck 1.42.12 (29-Aug-2014)
NSM-SENSOR-2: clean, 11/45498368 files, 2905980/181964288 blocks
[pgaltieri@jackstraw ~]$ sudo fsck /dev/sde1

NSM-SENSOR-1: clean, 32/46080000 files, 2993510/184320000 blocks
It only reports errors on this drive.
Should I be concerned about what smartd is saying? How do I, if
possible, correct this?

VNC and sound
by Chris Kottaridis
I am running Fedora 22 on a machine that is off in a closet and am using
VNC to access it from a machine at my desk. I followed the instructions
in System Admin guide chapter 8:
https://docs.fedoraproject.org/en-US/Fedora/22/html/System_Administrators...
I successfully got Tiger VNC server working. it was quite easy. Cudos to
everyone involved to make that so simple.
My VNC client is Windows TigerVNC version 1.5.
I don't seem to get sound. It doesn't seem to come out on my VNC client
or on the VNC server's sound card. My remote machine is close enough
that I could run a wire from it's sound card to the speakers on my desk
if that is easier. But, right now I can;t get the sound to come out the
VNC server sound card.
Any pointers or recommendations are appreciated.
Thanks

Fedora mirror speed's are low!
by Mihuleac Sergiu
Hi!
I'm from Romania, the speed from Fedora repo mirror is very low (from
50kb/s to 1 mb/s when it's good, usually the download speed stays
between 50 and 150 kb/s with the official repos and over 1 mb/s with
other repos ) when doing updates and when I install packages with dnf. I
tried using fastmirror module but I see there is no change and I lose
even more time because of the search for the best mirror.
1. What can I do to resolve this issue?
2. Is there a way to manually test mirrors and chose the best one for me?
3. How do I know witch mirror can I trust?
4. Where can I find a mirror list?
5. How can I create a local mirror?

Best Wishes,

Hello,
I cannot any more make CRT+C ctl+V under nedit as soon that there are

Is nedit still maintained?
I would be happy to use another editor if I find one which let me

Thank for any help.
