• How to migrate user settings and data to new machine?

  - by torbengb

  I'm new to Ubuntu and recently started using it on my PC. I'm going to replace that PC with a new machine. I want to transfer my data and settings to the nettop. What aspects should I consider? Obviously I want to move my data over. What things am I missing if I only copy the entire home folder? This is a home pc (not corporate) so user rights and other security issues are not a concern, except that the files should be accessible on the new machine! Please take into account that the new machine is a nettop that doesn't have an optical drive and doesn't allow me to hook the old SATA disk into it, so any data transfer must be handled via home network (I can have both the old and the new machine turned on and connected to the home LAN) and I have an USB thumbdrive with limited capacity (2GB). This sounds like it might limit the general applicability, but it would in fact make it more general. I'll make this a wiki topic because there could be several "right" answers. Update: Or so I thought. I don't see a choice for that.

• How GZipped contents are transfered on the web?

  - by PJ

  I heard that static contents like CSS and JavaScript can be better delivered in GZip format. And Content Developer Network (CDN) always does so. However I don't understand how the format works. First when I tried making a gzipped file via command-line. The file extension is .gz. This is different from .css and .js. How do browsers recognize which file is gzipped or not. Second, how browsers "decompress" files? I dragged my index.html.gz onto my browsers. But no one worked. How do such gzipped work in the real world? What do I need to do if I want to serve CSS/JavaScript using Gzipped format.

• How long can you be out of the MS market before it affects your career [closed]

  - by dave

  I've been working with .Net since it first came out and have done my best to use the latest and greatest things from Redmond. That being said, I've been working for the past year in the Python/Unix/Web world. In order to keep myself relevant in the MS world, I've been working part-time on a WPF project but I do not know how much longer that work will continue. So my question is: If I were to move totally to the Unix/Python/Web world, how long could I stay there before it starts getting hard to get another MS job? I am trying not to burn bridges in my career as I've found MS jobs pay better and tend to be more plentiful. PS: I like my Python job since it is something new and I get to work from home. It has provided a different view on coding that I've found useful. EDIT: I was out of the MS market for 12 months before attempting to get another MS job. No-one said "Gee you've been gone a while" but I did get a conspicuous lack of responses to job applications. My feeling is that the head-hunters do not bother to look beyond your last job. In the end, I got employment via my own network rather than the pimps. So, to answer my question: "not long, especially if you trust your career to head hunters."

• Updating an ADF Web Service Data Control When Service Structure or Location Change

  - by Shay Shmeltzer

  The web service data control in Oracle ADF gives you a simplified approach to consuming services in ADF applications, and now with ADF Mobile the usage of this service seems to be growing. A frequent question we get is what happens if the service that I'm consuming changes - how do I update my data control? Well, first we should mention that if you do a good design of your application before you actually code - then things like Web service method signature shouldn't change. The signature is the contract between the publisher and the consumer, and contracts shouldn't be broken. But in reality things do change during development stages, so here is how you can update both method signatures and service location with the Web service data control: After watching this video you might be tempted to not copy the WSDLs to your project - which lets you use the right click update on a data control. However there is a reason why the copy is on by default, it reduces network traffic when you are actually running your application since ADF doesn't need to go to the server to find out the service structure. So for runtime performance, you probably should keep the WSDL local.  I encourage you to further look into both the connections.xml file where your service location is saved, and the datacontrols.dcx file where its definition is kept to get an even deeper understanding of how ADF works underneath the declarative layers.

• LAN speeds and firewall/switch connections

  - by microchasm

  I have a small network with about ten users. All workstations flow into a Dell PowerConnect 3424 which then has a single link to a SonicWALL firewall and from there to a cable modem. More important than internet connectivity is speed between machines (specifically a Windows Server box on the LAN which everyone uses simultaneously). I believe the 3424 has gigabit connections, but they look like they're for stacking. Is there a way to test the speeds on the LAN to see where the speeds are at? Is there any low-hanging fruit insofar as increasing speeds?

• Restore access to Cisco Connect after changing router settings

  - by StasM

  I have recently bought Cisco Valet Plus (M20) wireless router (which I recognize now was a mistake, but nevermind). It has two setup options - Cisco Connect software and web-based setup. Cisco Connect software allows changing very small set of settings, web-based setup allows access to almost all settings, except settings for guest network. The problem is that when I use web-based setup, Cisco Connect after some changes refuses to talk to the router, so I can't change guest settings anymore (since web interface doesn't allow to change them). It must be because of some config parameter not matching or some password set wrong - but I don't know where Cisco Connect stores them. So, does anybody have any idea how to make Cisco Connect talk to the router again once I changed the settings through the web interface?

• Blank screen after GRUB (64 bit) - cannot install Ubuntu

  - by peGGi

  My laptop's specs: Lenovo IdeaPad Z570 Intel Core i5-2410M @ 2.3Ghz 6 Gb RAM DDR3 640 Gb ATAPI Hard-disk Drive @ 5,200 RPM NVIDIA GeForce G520M with Optimus switching technology Broadcom 802.11n Network Adapter REALTEK soundcard Windows 7 Home Premium 64-bit I downloaded Ubuntu Studio 11.04 and burned the iso image onto two different DVDs, using two different programs (one DVD is RW, the other is just R). I verified the hash MD5sum thing. I get as far as GRUB with the 4 options (install, advanced install, disk verification, system rescue) but no matter which one I select, I get a blank screen and nothing happens. The DVD drive spins down after about 30 seconds. Also just before the GRUB screen I get a message saying Error: "Prefix" is not set. I'm not sure if that's relevant. I have tried all the options using both DVDs. Same thing happens. I have changed the graphics setting in BIOS to UMA or Optimus, but still happens either way. I've tried booting with the wireless switch turned off, same thing happens. I downloaded 'vanilla' Ubuntu 64-bit and burned onto a CD, and the same thing happens. I have downloaded Ubuntu 32-bit and I am able to boot from the live CD (interestingly the wireless card won't work, but that's maybe another issue). I have searched extensively through these forums and other sites but I can't see anything that will help me. Is there something I'm missing? I'd really appreciate help on this. The laptop is less than 2 weeks old. I was so looking forward to getting Ubuntu Studio up and running. I've gone about as far as my technical abilities will allow.

• SpeedTracer NETWORK_RESOURCE_RESPONSE vs NETWORK_RESOURCE_FINISH

  - by Ben Flynn

  I'm using SpeedTracer with GoogleChrome to measure the load times of requested resources. The SpeedTracer site says: NETWORK_RESOURCE_RESPONSE "Indicates that the renderer has started receiving bits from the resource loader" NETWORK_RESOURCE_FINISH "Indictes a resource load is successful and complete." In my mind that means we would always see a network resource response (bytes are arriving) before we see a finish (all bytes received). This doesn't seem to be the case at all. Here is a sample: Request Timing @33519ms for 926ms Response Timing @34445ms for -847ms Total Timing @33519ms for 78ms I'm guessing response time isn't supposed to be negative. Can someone explain this or is this a bug? I'm using Chrome 10.0.612.3 dev with a SpeedTracer I downloaded today.

• How do I mount my Android phone?

  I'm puzzled because my phone used to just appear when I plugged it in. It doesn't anymore and The development options are definitely set to allow USB debugging.

I don't get any Click here to connect via USB alert either. I'm not even sure whether the issue is my phone or my computer. It seems odd that it isn't even appearing in lsusb Not for nothing, the thumb drive on my keyring also does not appear in lsusb -- I've tried both in a bunch of different ports. I kind of assume the thumb drive is just borked, but it could be my OS.

• Firmware/driver for Broadcom wifi card, PowerBook G4 running Ubuntu 12.04 [duplicate]

  - by user107831

  This question already has an answer here: How to Install Broadcom Wireless Drivers 40 answers This is my first time working with Ubuntu (or Linux), so please be patient. I am running Ubuntu 12.04-powerpc "Precise Pangolin" on a Mac PowerBook G4 with 1.67GHz processor. The firmware/driver for the wifi card is missing. For reasons not worth explaining, I cannot physically plug the computer into the network. I have another computer, a MacBook Pro running OSX, from which I can download files and port them by USB thumb drive. The wifi card in the PowerBook G4 is by Broadcom. The chip is BCM4306, rev. 3. The PCI number is 14e4:4302. I have downloaded b43-fwcutter_015-14_powerpc.deb and dropped it into the Home folder on the Ubuntu machine. However, it will not install. When I double-click, it opens with Ubuntu SoftwareCenter, but the "Install" button is inactive: I can't click it. There's a message beside the inactive button saying, "An older version of 'b43-fwcutter' is available in your normal software channels. Only install this file if you trust the origin." If I "right-click" the .deb file and open with Archive Manager, it shows me the "DEBIAN" and "usr" folders, but I'm unsure what to do from there...and fairly certain this is not the right way to do things. Maybe I have the wrong version of b43-fwcutter for my machine/version of Ubuntu? The documentation for this problem is a mess. It refers to all sorts of out-of-date Ubuntu versions and to an array of different "cutter" and firmware files. Maybe I'd be able to figure this out if I were a more seasoned Ubuntu user, but I have no idea why Sofware Center won't let me do the install. I would be VERY grateful for an explanation of how to get the wifi card working on this machine again. Thank you!

• Subdomain still times out after set up a month ago

  - by user8137

  I'm a newbie on this and this has probably been asked already but the subjects online were close but too vague in there answers so I've probably really messed this up. I would really appreciate specific step by step instructions. This is what I'd like to do: use the subdomain www.high-res.domain.com to be accessed by external customers with specific permissions to access the site (like ftp). We use Network Solutions to house domain.com. We recently added a new ip address to point to www.high-res.domain.com. I gave the ip address to the company that hosts our website. I pinged www.high-res.domain.com and it points to the correct ip address but still times out. It’s been a few weeks now and when you ping it, it still times out. C:ping XXX.XXX.X.XXX Pinging XXX.XXX.X.XXX with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for XXX.XXX.X.XXX: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss). Tracert times out as well. I even went to DNS tools and a few other sites for checking this and it shows the same thing. I recently went into the DNSmgmt on our server (wink2k3sp1) and created an A record under the DomainDnsZones which translated to a Cname when you look at it. Under the Domain it has two entries one to the subdomain and the other to the website host each with separate ip addresses. Is this correct? The website people are too busy on another project to research it further and my friends haven't gotten back to me. Please help. Thanks KK

• would a dynamic wan disrupt a static lan?

  - by JohnMerlino

  So I found out that the cable company use the DHCP to assign the public ip address dynamically. So a subscriber's public facing ip address can change during the length of their subscription. Now what if you remove DHCP on a particular computer, which you plan to use as a web server, so that the machine has a static, unchanging IP address. If the public ip address was to change, would this confuse the Network Address Translation (NAT) and cause some sort of disruption? Please answer in layman terms, as I'm still grasping concepts here. thanks.

• Windows Virtual PC File Copy from host very slow

  - by Shiv Kumar

  I have a Windows 7 desktop on which I've installed Windows Virtual PC and an instance Windows 7. I also have virtual XP instance on the same host. The problem I am having is that copying files from the host to the virtual machine is dog slow. I'm talking 17KB/sec. The host machine has a gigbit NIC. While using the XP virtual instance to do the same I didn't notice a huge difference but on the Window 7 virtual instance the time is really slowing me down. Is there something I need to do (settings) to fix this? I've attached an image of the Resource monitor (of the virtual Windows 7 instance) that shows my network traffic going in bursts rather than relatively steady. The files are on a "public" folder on my host machine.

• How do I get wireless and video working on a Sony Vaio vpc-z21x9r

  - by Alex

  OS: Ubuntu 11.10 Kernel: 2.6.37.6 Laptop: sony vaio vpc-z21x9r The problem: I can't change level of screen backlight; also can't enable wi-fi. While using 3.0 kernel everything is ok, but the laptop discharges too quickly. Results for lspci 02:00.0 Network controller: Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 5f) VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) there is no wlan0 in ifconfig -a too. I've fount that kernel should already have drivers for this graphics controller, but when i load up in restore mode, it writes "fall" while trying to load up some video drivers. To change the level of backlight i've alrady tried: xbacklight -set XX , smartdimmer -s XX and got this init_ nvclock() failed! also sudo setpci -s 00:02.0 F4.B=XX with no results. As for wi-fi, i've found driver but i don't understand how to install it. Here it is How can I fix these problems? Thank you for your help and time! Also tried to fix problems with backlight writing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor Still no results. Is there any sense in recompiling kernel, I mean 2.6.37.6. Can it make any improvements in the situation?

• HTTP traffic through PIX VPN from outside site

  - by fwrawx

  I have a remote site with a website that only allows access from the outside IP assigned to our local PIX. I have users connecting to the local networking using a VPN that need to be able to view this remote site. I don't think this works because the packets want to come in and go out over the same (ext) interface. So I'm looking for a way to make this work using the PIX or setting up a service on a server on the local network to act as a middle-man for the HTTP requests. The remote site doesn't support setting up a VPN to our PIX. The remote website is dishing out pages over a non-standard port. Can I use squid or something similar to proxy just one site?

• How to reset Nexus One to Android 2.2.1 or 2.3?

  - by jblocksom

  I have a Nexus One (with the radios for the AT&T network) which has an old beta version of 2.2 on it. It doesn't receive over the air updates, and I'd like to get it running something more recent. Where can I find a download for Android 2.2.1 or 2.3? There's a link to an updater on Google's site that's given by numerous blogs but it's always broken. It's kind of bizarre to me that this phone is stuck in an OS limbo since it won't receive updates and there's no place to download the latest.

• Recording slow web stream

• Avoiding double NAT with PPPoA connection

  - by user498429

  I've got an ASUS RT-N56U wending its way to me and have been thinking about how to set this up on my home network. I currently have a Netgear DG634g V5 and was hoping to use this device as a modem only, with everything else being done by the router. Problem is, my ISP uses PPPoA and the asus seems only to support PPPoE. I'm aware that a double NAT configuration should be avoided and I've seen some instructions here: http://www.tomshardware.co.uk/forum/33700-17-ultimate-modem-router-setup-thread Specifically, I was going to follow the guidance in the section entitled "Chaining Two Networks Together In a Cascading Fashion (Modem handles PPPoA)". That seems like it could work. However, is this a double NAT configuration or even a good way to do it? Would UPnP still work? The other option, I understand, is to buy the Draytek Vigor 120 but I'd ideally like to avoid the cost of that if its not necessary.

• It's Raining Solaris Training

  - by rajeshr

  That the popularity of Solaris 11 is only growing is clear from how regular the training sessions have been around this product. It's such an excitement to be going around sharing knowledge on Solaris, more so to explore the nitty gritty of many new and evolving features. Trust me, it's only getting better! In the process, just like in the past I stumbled on several individuals, each teaching me a lesson or two. I'm grateful. And if I've managed to get over the laziness to come back to the web logs with a collection of class photos from the last couple of months, it's because of a sense of gratitude to all 'em in the picture below. Solaris 11 Network Administration Pilot Teach in Bangalore. Sun Identity Manager (n.k.a Oracle Waveset IDM) Deployment Fundamentals Training. I'm missing from the snap because these delegates sat well over 10,000 Kms away from where I taught this class from, but were kind enough to help me associate a face with the voice by sending me a group photograph. If you want to attend one such OU program cutting down the travel, try OU's Live Virtual Class (a.k.a LVC) . Transition to Solaris 11 in Mumbai. Solaris 11 Advanced Administration Session in Bangalore. Transition to Solaris 11 in Mumbai. Attending Gary Riseborough's Exadata Training at Singapore.

If only the participants of each LVC session belonged to the same location, there would've been additional three group photographs occupying this space! Thank you everyone for many many memorable moments.

• connect to paltalk server using a proxy

  Hi I want to use paltalk, which is a kind of chat software, but the ports that this applications uses are closed in my country. What I need to do is to use a proxy server. Unfortunately the software itself does not provide a proxy setting. I though it would be possible to run paltalk on an O.S. installed on a virtual machine (say virtualbox) and configure the network setting of virtual machine to direct all its traffic through a proxy on host Operating system, but I could not find a way to do so neither. can anyone please help me?

• Cannot access personal website from home IP. More details inside.

  - by GX67

  This is a recent problem I've been having. My site can be accessed from almost everywhere else except from my home IP, where I do most of my editing/updating, etc. I've tested my connection from my school's network, a friend's connection from out of state (multiple states), and through a tethered connection with my friend's Android. It works in all those cases, both viewing, accessing the cPanel, and using FTP. Here's the problem that happens to me when I try to view it from my home IP: The page times out in Firefox, IE, and Chrome. Using the cmd, I ran tracert and ping, both as failed attempts. Log here. downforeveryoneorjustme.com says my site is up. So do the other site checkers. I can't access my cPanel or FTP accounts. I can't access the host site. (I use perfectz.info for hosting, and I can't access their site either.) System settings: No firewall enabled. Ports are seemingly properly forwarded. (e.g. The ports are open in the router settings, and are open everywhere else.) I have an email forwarder set up from the cPanel that works just fine. (i.e. I can receive emails sent to that address. If any other information is needed, I'll do my best to provide it. UPDATE @ilhan: I use two things: 1) The site cPanel from in-browser. 2) Dreamweaver CS5 FTP. @Matthias: I tested both, and it passes the dual stack with a 10/10. What should I do then?

• How can I migrate websites between two identical servers?

  - by edude05

  I have two servers that have a nearly identical (software) configuration. We are upgrading the web servers to run windows server 2008 R2, one already is however the main one (that currently has sites) is on WS2008. Now, the old server is ns.mydomain.com and the new server is ns1.mydomain.com. Since dns automatically fails over to ns1.mydomain.com I'd like a way to move all the vhosts to the new server. Is there an automatic way to move / recreate all the vhosts on the new server? I have figured out how to migrate the DNS records already DNS Migration and since both servers are on the same private network migrating the website data isn't a large issue. Every site is running PHP & MySQL and the MySQL server is external so the records won't have to be moved. Thanks
