Why is Pulseaudio not daemonized by default?
by Fedora User
I must be missing something. Running pulseaudio as a daemon SEEMS to be
much less troublesome. It's easy enough to change in the conf file.
Audio device=Intel Corporation 6 Series/C200 Series. I assume that this
is a fairly common. There must be a downside that I have not
appreciated.

F16: Raid1 /home failing to restart cleanly
by 'Chris Hall'
I have a /home partition which is set up as a Software RAID1, using /dev/md0.
When I reboot the /dev/md0 fails to come up cleanly. So far it has come back each time, but nearly every time it comes up with one of the two members of the RAID array missing. I can mdadm /dev/md0 --re-add /dev/sdb3 -- and all is apparently well again. But I have this partition as RAID for a reason, and it scares the bejazus out of me each time :-(
Any clues as to what spells I have failed to cast ?
Thanks,
Chris

System transit time, Latency -
by Bob Goodwin
How can I measure system transit time in this satellite system.
I don't need great precision, just a rough idea of the time from
here to the satellite, back down to the earth station/gateway,
destination, and return.
I used to look at ntpq when I wanted a clue but that is
apparently not available for F-16/64?
I installed "latencytop" but I don't see how to use it for this
purpose?

Wired vs (bad) Wireless communications speeds
by Philip Rhoades
People,
Between my laptop and my server there is a WiFi modem and an ADSL
router and I think the comms is too slow. The device speed for each is:
Server: Intel 82567LF Gigabit: 10/100/1000 Mb/s
Belkin Wireless F5D7230-4v7: 10/100 Mb/s
Belkin ModemRouter F1PI241ENau: 10/100 Mb/s
Asus Zenbook UX31: ath9k: 54 Mb/s
RJ45 via USB: 10/100 Mb/s
and Cat5 cables.
On an unloaded network I can get about 6.5 Mb/s when I use the cable
connection to the laptop but nothing better than about 1.5 Mb/s for the
wireless connection - and even that is when the laptop and the wireless
router are only about 1.5m apart (the XFCE network icon shows connection
quality is then at about 90%).
Anyone know why the wireless performance is not better than this?
Thanks,
Phil.

F16: ssh-add: Could not open a connection to your authentication agent.
by Ranjan Maitra
Dear friends,
Just updated to the latest kernel 3.3.1 and rebooted and tried to get
everything going but I get:
$ ssh-add
Could not open a connection to your authentication agent.
$
What is this supposed to mean? This is perhaps the first time I have
seen this error in almost 15 years on linux. How can I fix it?
Of course, the kernel update may have nothing to do with it. I also
updated kernel-headers, libtasn1 and taglib at the same time.
Many thanks and best wishes,
Ranjan

Fedora 16: dropping spontaneously into "Emergency Mode"
by 'Chris Hall'
Having recently installed Fedora 16, replacing Fedora 14, I am now plagued by the thing spontaneously falling into "Emergency Mode"... "Welcome to Emergency Mode" ha ha !
The last things in /var/log/messages are:
Apr 7 14:55:54 hestia systemd[1]: Job dev-sdb5.device/start timed out.

As it happens, /dev/sdb5 is a back-up partition... so is not in use most of the time... so (assuming this is the trigger for the system falling over) I don't know why it was suddenly felt to be essential to be able to start it... it is mounted when the system is booted.
The other suspicious character is ntpd to whom somebody has sent a SIGTERM and who appears to have sent a lot of "stuff" to the logging, which is nowhere to be seen :-(
Can anybody point be in the direction of what is going on here, and how I may be able to restore some stability to my Fedora 16 installation, which is currently falling over about once a day at random.
Thanks,
Chris

yum file\dir ownership couple of questions
by Frank Murphy
as this is not specific to testing, asking here.
I want to use an /nfs/ mountpoint as the yum cache.
edit /etc/yum.conf done.
is it possible to yum update as named user, which is me.
with out having to do a su\sudo *1
I can chown -R root:user the cache /nfs/yum/$release/$arch,
or would user:root be more suitable?
for browsing\modifying with file manager (Thunar),
or command line as user.
70/30% on the rl3/rl5 usage
There doesn't seem to be a group to join for yum\system updating,
root:root seems to own all yum* files\dirs.
Though, was under the impression apps, had to own all dirs they created
https://fedoraproject.org/wiki/Packaging:Guidelines#File_and_Directory_Ow...
I'm probably wrong if yum is a filesystem app.
How can a dir be co-owned?
Is this different to the usual root:something idea?
*1 Only for this yum idea.
Otherwise su\sudo is fine for other operations.

Frank
