Fedora 17 lost+found in / directory after install
by George
Hi all. I am a new user of Fedora 17. I am studying for the Linux
certification.
I installed Fedora 17 using Vmware Workstation 8. After I completed
the installation I checked the directories to insure that everything was
installed correctly. When looking at the / directory using the ls command
I discovered that /lost+found file was there. I thought that this file
is supposed
to show up when you choose a directory as a mount point. Could anyone
help me understand why this happened and if the lost+found file is not
supposed
to be there how can I correct the problem?
Thank you.

I don't really understand your response here.
To repeat, the imac is working, apparently with full internet access,
via *wired* connection. The prior use of wireless internet on the imac,
has been turned off.

YES, sorry, 'just' a typo on my part,
it has always been 68.94.156.1
which seems to say both of the DNS numbers I am using are valid.

This now appears not so, i.e. the data in resolv.conf appear correct.

Does this tell me anything? is ns1.pbi.net a DNS number I could/should use?
In addition to the two I now have?
I did pull the new modem power cable,

No help on internet:

It seems I don't need to correct faults in the DNS numbers,
so does it still make sense to restart NetworkManager?
Exactly how would I restart it?
-- chkconfig?
-- some systemd command?

RE: att-uverse new, can't access internet
by Jackson Byers
Tim,
thanks much for your reply.
I am still much in the dark re DNS servers
More on that below

I think there is a router, inside the uverse-modem.
>> --enter a 10digit key found on back of new modem
>If that 10 digit key is something looking like this,
>"00:1A:92:D8:F2:79"
NO, it is just a set of numbers w some spaces, no ":"
I don't think this early thing re wless att had me do on the imac
is playing any role any more.
As I said later the imac is now running w wired internet access,
"Airport" wless no longer being used,
seems to have no DNS problems.

Amen.
What I had just before the attuverse:
an old pacbell adsl modem
a linksys router, plugged into that adslmodem.
my f16box i think connected into that router.
from another room,
the imac ethernet connected i think into that router.
2 more things connected but not used for several yrs:
a laptop, also i think plugged into that router.
some type of wless access point plugged into that router.
What we have now since the att uverse install
--above adslmodem, router,laptop, access point disconnected.
--new uverse modem, tech said it had a router in it,
with its own fwall.
I can't see any off/on switch on that uverse modem.
Would it be worth trying to unplug, and plug back in the black power cable?
There is also a uverse WAP, used only to get the uverse tv signals
to our two tvs. As far as I know this has nothing to do with our computers.
f16box, imac both ethernet connected to that uverse modem.
3 new pieces of some type of electronic gear now under my desk
also connected to the uverse modem.
The uverse install tech did not explain their use to me,
or even point them out to me.
Evidently necessary electronics parts needed for the uverse setup.
I only noticed them after the tech left.
The imac has been working with the new uverse, with
working internet wired connection, no DNS problems.
imac no longer using the Airport wless
which we used only for 1-2 days.

what does this tell me?
that 64.94.156.1 is no good, or stale, or???
that 206.13.31.12 is good? valid nameserver?
that 151.164.129.3 is good? valid nameserver?
if 206.13.31.12 is a good namesever, since it is already in my f16
/etc/resolv.conf
shouldn't I have internet access?
do I have to do something like restart NetworkManager?
NM has always just been a silent thing, not to be messed with.
If it is worth trying how would I do this?
I am not at all up on systemd.
I haven't had cause to use chkconfig for years, no need.
Again, thanks for help

dump/restore selinux query
by Dr J Austin
Hi
I have recently used a bootable F17 memory stick (fully updated) to
dump/restore an un-mounted Centos 6.3 system root (/) partition
to a "clone" backup partition on a separate disk.
I obtain SELinux error messages during the restore phase
Does anyone (Daniel?) know:
Will this be a problem if/when I need to use the backup?
Regards
John

A note on youtube-dl
by Marko Vojinovic
Hi folks! :-)
Just a small note... I just tried and found out that the youtube-dl doesn't
work anymore. Reading the youtube-dl FAQ page, it says that YouTube has
changed the protocol again (since September 2012) and that we should update
the script to the latest version.
The "sudo youtube-dl --update" works as expected (and once updated, it
downloads stuff fine), but I guess someone should notify the relevant package
maintainer to update the rpm package, so that it gets pulled in with an
ordinary yum update.
I wasted half an hour hunting this down, so that noone else needs to. ;-)
HTH, :-)

Without the capitalism the customer can expect zero improvement,
particularly with hardware. What incentive would I as a person trying to
make a living off clever video drivers to continue doing so?
What has capitalism to do with that?
It is about freedom of choice.
If you think you can build something better or cheaper, you must have the freedom to do so.
Otoh, if a state-owned-company has "a Plan" to produce the next five years or so, crap at bargain process, so be it.
Just as any customer has the freedom to choose any product.
And let the customer decide what is important to him: price, feature, quality, stability, support...
