oovoo.com
by Gregory P. Ennis
Dear List,
I was asked to assist connecting a Fedora linux system for video
conferencing with oovoo.com. It is apparent that they support Mac and
Windows.
Does anyone have any experience in using the Mac installation for oovoo
for Fedora? Can anyone make recommendations for connections that allow
video conferencing with Fedora.
Thanks much

Question on shredding a terebyte drive
by Dean S. Messing
I have a terebyte sata drive that I need to securely wipe clean. It
originally had 2 partitions. I deleted them using `fdisk', rebooted,
and then as root ran
shred -vz /dev/sdd
The drive is capable of about 60MB/sec, but shred is only "shredding"
about 25MB every 5 seconds according to its output. Since the default
number of passes is 25, this works out to about 5 days.
The `shred' process is running at 100% CPU, presumably computing
the special random patterns for erasure. Since I have 4 CPUs
would creating 4 unformatted partions on the drive and then running
something like:
shred -vz /dev/sdd1
shred -vz /dev/sdd2
shred -vz /dev/sdd3
shred -vz /dev/sdd4
in parallel cut my time? Would be just as secure?
Thanks

No wireless (waiting for authorization) after awake from suspend
by Gene Smith
F15 on new HP dv7-6195 (i7/sandy bridge) cannot regain wireless
connection after awake from suspend. In KDE, I see notification "waiting
for authorization" and then a "key" icon appears over the wireless icon
in tray. In gnome, a dialog pops up with my wireless key (correctly
filled in) for me to confirm. After confirming, it keeps popping back up
every 30 seconds or so. Never asks for my password, just wireless key.
It is set to be stored in encrypted file.
Wired ethernet connection works fine before and after suspend and
wireless works fine only before suspend.
I have tried rmmod / modprobe to remove / add back the wireless driver.
Also, set selinux to permissive thinking it might be that type of problem.
Only reboot, so far, brings wireless back.
Any ideas?

Fun and games with 3TB hard drives.
by linux guy
Today I bought 2 3 TB hard drives to use in my new server.
I'm writing this in case other people aren't aware that some of the
traditional hard drive management methods don't work for drives larger than
2 TB.
Specifically, fdisk and MSDOS type partition tables.
Here is how I created a single partition on my 3 TB drives.
Via parted.
#parted -a optimal /dev/sdb
(parted) rm 1 <- this removed the 2TB partition that fdisk made.
NOTE: fdisk has a 2 TB limit, apparently forced by MSDOS style partition
tables. Ever heard the story about how the width of a donkey ultimately
determined the diameter of the space shuttle ?
(parted) mklabel gpt <- this is NOT making a label for the drive. "man
parted" is your friend.
(parted) mkpart primary ext4 1 -1 <- this makes the partition itself, using
the entire drive, which is what I wanted.
(parted) print
(parted) quit
# mkfs -text4 /dev/sdb1 <- this formats the partition
#e2label /dev/sdb1 myth <- this gives it a label, as used by mount in
fstab, ie "LABEL=..."
Via gparted.
It turns out that the whole process can be done from within gparted, if you
know what you are doing.
The first thing you need to do is create the partition table.
IF you have used fdisk on the drive previously, the partition table type is
going to MSDOS, which has the 2TB limit. If you continue with the MSDOS
partition table, gparted will allow you to select a 3TB partition to make,
but it will give you the following error:
partition length of 5860528002 sectors exceeds the
msdos-partition-table-imposed maximum of 4294967295
To get around this, select Advanced on the partition table options window
and set the partition table type to gpt.
Then you can proceed as you normally would to partition a drive with
gparted. Ie add new partition(s), set the partition type, labels, etc.
At this point you have an ext4 formatted 3TB drive.
However, in F15 KDE at least, it doesn't seem to automount like a drive with
an MSDOS partition table. The drive will not automatically appear in the
Places column in Dolphin, for example. Nor will it appear in the list
created by df.
However, it is available to manually mount. Ie, #mount /dev/sdb1 temp,
just like the old days.* And once you do that, it appears in the df list,
though still not in the Places column in Dolphin.
I hope this helps someone.
*This might be particular to my machine being that the drive is a hot swap
SATA device and I did not remove it and replace it. However, drives with
MSDOS type partition tables auto mounted using the very same command
sequence.

Best FOSS alternative for skype?
by Marko Vojinovic
Ok, I just lost enthusiasm in further use of skype. Being closed source was
bad enough already, but I tolerated it due to its good-enough quality,
reliability and free-of-charge use for skype-to-skype calls. But now that
Microsoft is taking it over, I suddenly lost faith that these good features
will still be there from now on (not to mention Linux support).
Thus the question: is there a FOSS VoIP app that provides roughly the same
quality, reliability and free-as-in-beer service?
I do know that there are such VoIP apps, but I am not familiar with the
quality of service, availability and accessibility of each of those. I am
willing to migrate and start persuading my existing skype contacts (which are
scattered all over the globe) to migrate to a FOSS solution as well. But I
cannot do that if this alternative does not provide functionality that at
least matches that of skype. It has to be up to the task.
So which one is on the top of the list, in your opinion?
TIA, :-)

Samba problems. Samba master fight with Linksys E4200 wireless router with storage ?
by linux guy
I'm having a lot of trouble setting up a Samba share on a virgin F15
install.
Right now everything works until I click on a shared file (via Samba). At
that point I get a "the file or folder smb://nas/TEST does not exist" error.
This is what smbclient shows for 192.168.1.10, ie nas, my Samba server.
$ smbclient -U% -L192.168.1.10
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.5.11-71.fc15]

For the longest time smbclient showed there was no master. Today, my
E4200 wireless router, which has file sharing is showing up as master. I'm
not sure if I should be OK with that or not. Given my smb.conf file, I was
expecting nas to be the master. There doesn't appear to be a way to turn
file sharing off in the E4200. Maybe if I set the workgroup on it to null ?

Any ideas on why Samba isn't working ?
FWIW, I only used SWAT for looking at potential settings and setting a
couple globals. The rest I've been doing by hand. And I've been
restarting nmb and smb manually after each change.
I'm finding the online documentation for Samba to be umm... wanting. I'll
post up a little HOWTO when I get my NAS going.

Atheros AR9285 wireless & F15
by Greg Woods
I cannot get wireless to work on my new Sony VAIO VPCEG laptop. It has
the ar9285 chip in it. I am thinking this is a bug in the driver and
wondering what I should do about it. Before I file an official bug
report (with Fedora?), I want to know if anybody else has a machine with
this chip in it that is working. I'd like to rule out my own stupidity
first.
I can state the following:
1) There is a hardware wireless switch, and it is on
2) I have tried both 2.6.38 and 2.6.40 kernels.
3) I have tried the latest compat-wireless driver from kernel.org
4) iwconfig can see the wlan0 device, but ifconfig does not.
5) Clicking wireless within NetworkManager:
a) Airplane Mode shows as ON
b) Wireless shows as unavailable
c) Clicking wireless briefly turns it on and Disconnected, but then
it goes right back to Off/Unavailable
d) Turning off Airplane Mode appears to work, but doesn't change
anything in c) above.
6) The wireless works fine in Windows 7
What is *really* frustrating about this is that it briefly worked a
couple of times. During the install, it showed a list of available
wireless networks and I chose mine, and entered the password. Then once,
after several reboots for various reasons, it actually came up and
worked, but as soon as I rebooted again, I was back to the same old same
old and it has not worked since.
Does this sound like a kernel driver bug or something stupid I did?
Would it make sense to file a bugzilla against the kernel? Any chance
this would work if I installed F14 instead of F15?
Obviously, without wireless, the laptop is a $600 paperweight.

Pavilion dv6-3225dx under F14 -- mouse problems
by Paul Allen Newell
Hello to all:
I have a HP Pavilion dv6-3225dx that was installed with Win7 and I am
trying to dual-boot with F14. I've managed to do that, but I am seeing
totally wacko action out of the mouse (which is a touchpad with a
movement area and two "buttons" below"). The long and short of it is
two-fold
1) the right mouse button seems to be non-existent and, if there is a
left-mouse action to be had, it mirrors that. But for things that have a
distinct right-mouse action (setting the number of workspaces or pinning
the terminal to the upper toolbar), it doesn't see them
2) even though I have disabled scrolling on the touchpad, if I put two
fingers on the touchpad, it goes shooting all over the place (detailed
exam indicates it is getting a continuous y change and I can't figure
out what the x is doing)
I googled the machines and didn't see anything above and beyond hp not
having any drivers other than Win7. I looked into firmware under fedora
and didn't see anything for touchpads. When I did the initial install,
F14 barked about needing a firmware update, but that vanished once I did
a yum update.
I am not seeing any other problems with the install, but can't test too
far with a mouse that seems to like
"pick-drug-of-your-choice-so-long-as-it-is-an-upper"
Suggestions? ... I would hate to have to give up on a Fedora capability
for this machine as I want to do a dual-boot so I can eventually move to
"dumping" Windows.
Thanks in advance,
Paul

/var/cache/abrt-di
by Ranjan Maitra
Hi,
Looking at my files and diskspace, I note the following:
$ sudo du -sm /var/cache/*
1961 /var/cache/abrt-di
1 /var/cache/cups
1 /var/cache/fontconfig
1 /var/cache/foomatic
1 /var/cache/hald
1 /var/cache/jwhois
1 /var/cache/ldconfig
3 /var/cache/man
1 /var/cache/mash
1 /var/cache/PackageKit
217 /var/cache/yum
Googling on how to reduce this abrt-di beast, I came up with the
solution that you should delete the reports in the abrt GUI tool. But
these are all deleted for me, and I think there must be a better way to
remove this cache? Any suggestions on how to do this cleanly?
Many thanks and best wishes,
Ranjan
