RE: att-uverse new, can't access internet

Terry Polzin: >A simple disconnect and reconnect of your wired connection should renew >it's IP address and /etc/resolv.conf else why not just reboot. I have already rebooted many times, no help. My request on how to restart NetworkManager is more out of desperation, in the mad hope that kicking NetworkManager via "restart" might make my f16 capable of not getting that DNS failed error. Jack

Did anybody successfully install the proprietary Nvidia driver on Macbook Pro(EFI boot)?
by Andre Massing 04 Oct '12

04 Oct '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I am running fedora 17 on a Macbook Pro 6,2 with an integrated intel and a nvidia graphic card, lspci -v | grep VGA gives: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 330M] (rev a2) (prog-if 00 [VGA controller]) Unfortunately, there are two issues which the open source driver nouveau: 1. The laptop does not resume from suspend to ram after having been connected to an external monitor, this is bug https://bugzilla.redhat.com/show_bug.cgi?id=858798 2. I intend to work with Nvidias CUDA framework and therefore have to use their driver :( I tried to use both the nvidia-graphics.x86_64e kmod-nvidia* package from rpmfusion repo and the nvidia-graphics package from the atrpms repo. Using standard boot options, the boot process seems to hang just before gdm is started. Adding the kernel option nomodeset, the monitor gets dark after the boot process and after having connected a 2nd monitor I realized that actually the laptop monitor light was completely switched off. Is there any possibility to switch it on during the boot process? Any ideas or experience how to get the Nvidia driver running? Of course, any pointers or hints are very much appreciated!

Fedora 17 lost+found in / directory after install
by George 04 Oct '12

04 Oct '12

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. George

Help out Ask Fedora
by Matthew Miller 03 Oct '12

03 Oct '12

We just lowered the karma/reputation requirements for participating in Ask Fedora http://ask.fedoraproject.org/questions/, which means it's easier for new users to assign tags to questions, fix typos, and etc. If you're involved in Fedora, it'd be awesome if you could spend a few minutes each day looking at the site — answering questions if you can, but even just voting up the good questions and answers really, really helps. -- Matthew Miller ☁☁☁ Fedora Cloud Architect ☁☁☁ <mattdm(a)fedoraproject.org>

RE: att-uverse new, can't access internet

Tim, thanks much for your reply. I am still much in the dark re DNS servers More on that below >If you're running different computers and/or OSs on a network that >between changes. If you have a router between you and them, then that >shouldn't be a problem. The router would be what they see, all the >time, and what you connect behind it isn't any of their affair. .... 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. >You should probably describe your network in greater detail, >particularly what's between your ISP and your computers (modem/router, >ethernet hole in the wall...). >Some ISPs supply you with one public IP, and you'd need a router doing >NAT between you and them to share the IP between multiple devices. Some >ISPs give you multiple public IPs, and you can simply have a switch/hub >between you and them. >The more info, the less guessing games by us, and less advice that's >going to lead you down the wrong path. -- 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. -------------- DNS bash-3.2$ dig pacbell.net @64.94.156.1 ; <<>> DiG 9.6-ESV-R4-P3 <<>> pacbell.net @64.94.156.1 ;; global options: +cmd ;; connection timed out; no servers could be reached bash-3.2$ bash-3.2$ dig pacbell.net @206.13.31.12 ; <<>> DiG 9.6-ESV-R4-P3 <<>> pacbell.net @206.13.31.12 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 36167 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;pacbell.net.

A note on youtube-dl
by Marko Vojinovic 03 Oct '12

03 Oct '12

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, :-) Marko
