• Release upgrade crashes with "W:Failed to fetch http://host/debian/dists/oneiric/Release.gpg"

  - by Nolan Dillard

  My update manager told me that it has not checked for updates in the past 18 days, so I clicked the "check" button. It works just fine until a certain point where it says "Downloading release". The loading bar moves across the screen for a while on that message, then it just stops and says to check my Internet connection. I am fairly certain that my Internet is fine, as I can do anything else that I have tried, including installing software over the Internet. I clicked on "Details" and this is what turned up: Log

• apache2 installation conflicts with previous lampp content

  - by Fruit

  hej, i downloaded xampp-linux-1.7.3a.tar.gz and installed it manually, not with aptitude.

• SQL Server v.Next (Denali) : Another SSMS bug that should be fixed

  - by AaronBertrand

  Sorry to call this out in a separate post (I talked about a bunch of SSMS Connect items the other day), but Aaron Nelson ( blog | twitter ) jogged my memory today about an issue that has gone unfixed for years: the custom coloring for Registered Servers is neither consistent nor global. For one of my servers, I've chosen a red color to show in the status bar. Let's pretend this is a production server, and I want the red to remind me to use caution. I can set this up by right-clicking a Registered...(read more)

• How does Windows Remote Desktop Connection Work?

  - by Devoted

  How does Windows Remote Desktop connection work? An IP address is used to connect to the computer but....how can that IP be accessed from anywhere? If, for example, the IP address is 128.10.10.10, there MUST be another 128.10.10.10 somewhere else in the world. How does Remote Desktop know which one to connect to? Thanks so much EDIT: Thank you! Answers cleared this up quite a bit. But if my remote desktop connection suddenly stopped working and I didn't change anything, how do I even start to diagnose what may be the problem? I can remote connect to it from a LAN computer though...

• Stop YouTube Videos from Automatically Playing in Chrome

  - by The Geek

  If you’ve actually used the internet before, you’ve probably come across a page with an auto-playing YouTube clip, and chances are good it was a rather annoying one. Here’s how to stop them from starting automatically in Chrome. We’ve already told you how to stop them from automatically playing if you’re a Firefox user (best answer: use Flashblock!), but now it’s time for Chrome users to get their turn. Use the Stop Autoplay for YouTube Extension The great thing about this extension is that it stops the video from playing, but it allows it to continue buffering, so when you do feel like playing the video, it’ll already be downloaded—really useful for people with slower internet connections. There’s no UI or anything fancy, just head to the extension page and click the Install button. If you want to get rid of it later, use the Tools –> Extensions menu (or you can type chrome://extensions/ into your address bar), and then click the Uninstall link for that add-on.   Download Stop Autoplay for YouTube [Google Chrome Extensions] Using FlashBlock for Chrome If you really wanted to, you could just disable Flash across the board using FlashBlock for Chrome. Once you’ve installed the extension, you won’t see any Flash elements anywhere, and you’ll have to move your mouse over them and click to enable them each time. When I installed the extension the first time, I noticed that YouTube was already in the allow list. I’m not sure if that’s the default setting or not, but you can use the icon in the address bar, or the Options from the Extensions panel to get to the settings page, and from there you can remove anything from the White List that you wouldn’t want. Another nice feature about Flash Block is that it can also block Silverlight, or you could simply uninstall or remove unnecessary Chrome plug-ins.

• Running a defect php file cause error 500

  - by John Brunner

  When I address a PHP file, I always get an error 500. I've looked up the logs of my Apache server, and this displays that some includes etc. in the PHP file address files which don't exist on the server. They don't exist because I'm just testing my PHP file. But could it be achieved that the server runs the php file in every case, even when something is wrong? Every 30 seconds an entry is made in the error_log file which says [Sat Jun 09 17:55:07 2012] [error] [client 10.224.55.160] File does not exist: /var/www/html/index.html ... but there IS an index.html?!

• Kubuntu 12.04 - DNS Issues

  - by AndrewJesaitis

  Starting yesterday (6/11/12), I've been having many network problems. When requesting a page in chrome, the page hangs on "Sending request" and then will eventually timeout. I'm within a VPN that has it's own DNS server. I've tried to manually set my DNS through the Network-Manager applet and by editing /etc/network/interfaces. Having no luck I unlinked the resolv.conf file and dumped the contents of my old resolv.conf into it. Again having no luck, I deactivated the dnsmasq server in /etc/NetworkManager/NetworkManager.conf by commenting out the dns=dnsmasq. $ cat NetworkManager.conf [main] plugins=ifupdown,keyfile #dns=dnsmasq no-auto-default=D0:67:E5:EA:B6:6B, [ifupdown] managed=false $ nm-tool NetworkManager Tool State: connected (global) - Device: eth0 [Wired connection 1] ------------------------------------------- Type: Wired Driver: tg3 State: connected Default: yes HW Address: D0:67:E5:EA:B6:6B Capabilities: Carrier Detect: yes Speed: 1000 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.254.122 Prefix: 24 (255.255.255.0) Gateway: 192.168.254.2 DNS: 192.168.254.1 What is strange is that the network will work fine for a few minutes then start to timeout. A few minutes later it will work again. I'm unable to hit internal or external sites when it is timing out. When I $dig local sites, I receive no answer. I do receive an answer from google.com. At this point, I would usually blame the DNS Server, especially since when I change to Google's DNS server things work. But, I need to use our internal DNS to hit our internal sites. Nobody else is having issues and they are all using DHCP. This group includes one user who is using 11.04. At this point, I'm at a loss for what to do, so any help would be appreciated.

• Not all of your nameservers are in different subnets. Single point of failure

  - by user2118559

  Using VPS hosting and dynadot (domain registrar) DNS. Checked domain name with http://www.intodns.com and get some warnings Different subnets WARNING: Not all of your nameservers are in different subnets and Different autonomous systems WARNING: Single point of failure As understand to avoid the warning must have second Ip4 address and both the addresses must point to different servers? If both Ip addresses point to the same server, it does not help? I mean each server has own Ip address. If one server down, then visitors can access website (files) on another server? Is this the reason why need more than one Ip? Tried to point website to 2 ip addresses and after some time get warning from uptimerobot Connection Timeout

• Wrong source IP when accessing internet directly from TMG server

  - by jarod1701

  Hi everyone, after implementing a ForeFront TMG server I'm facing only one problem: After I added a second IP to the external adapter I had to manually set "NAT Address Selection" inside the network rule "Internet Access" to the first IP since all others would get blocked by the CISCO firewall. This configuration works as long as traffic comes from the internal network (e.g. browser on clients). Traffic from the TMG directed to the internet always carries the second IP as it's source address and gets blocked. All our other TMGs/ISAs are running fine and I never came across this problem- Does anybody have a clue, coz I don't?! Kevin

• Will a polled event system cause lag for a server?

  - by Milo

  I'm using a library called ENet. It is a reliable UDP library. The way it works is a polled event system like this: ENetEvent event; /* Wait up to 1000 milliseconds for an event. */ while (enet_host_service (client, & event, 1000) > 0) { switch (event.type) { case ENET_EVENT_TYPE_CONNECT: printf ("A new client connected from %x:%u.\n", event.peer -> address.host, event.peer -> address.port); /* Store any relevant client information here. */ event.peer -> data = "Client information"; break; case ENET_EVENT_TYPE_RECEIVE: printf ("A packet of length %u containing %s was received from %s on channel %u.\n", event.packet -> dataLength, event.packet -> data, event.peer -> data, event.channelID); /* Clean up the packet now that we're done using it. */ enet_packet_destroy (event.packet); break; case ENET_EVENT_TYPE_DISCONNECT: printf ("%s disconected.\n", event.peer -> data); /* Reset the peer's client information. */ event.peer -> data = NULL; } } It waits up to 1000 milliseconds for an event. If I'm hosting say 75 event driven card games and a lobby on the same thread as this code, will it cause any problems. If my understanding is correct, the process will simply sleep until there is an event, when there is one, it will process the event then come back here where potentially 5 or so events have queued up since so enet_host_services would return right away and not cause lag. I have been advised not to use multiple threads, will that be alright like this? Thanks

• Unable to access published programs on TS web access - win server 2008 OS

  - by varun

  I am using the TS Web Access feature provided by windows server 2008 to publish programs so that they can be accessed over internet using RDC client. I am able to access the programs from the intranet domain . However, when i try from outside the college network, i am only able to see the published programs but not connect to them as i get an error saying "Remote computer cannot be connected. The certificate subject name and the gateway address requested do not match." . pls note that i have created a self -signed certificate and installed on server myself. Also, i am using the direct IPAddress of the server as the gateway address. Since i am able to access programs from with domain , i suspect it to be a simple setting with gateway or certificate. Please let me know if any further info is required on this..any help is appreciated..

• Security Issue in LinkedIn &ndash; View any 3rd profile without a premium account.

  - by Shaurya Anand

  Originally posted on: http://geekswithblogs.net/shauryaanand/archive/2013/06/25/153230.aspxI discovered this accidently when my wife forwarded a contact on LinkedIn from her tablet, using the mobile interface of the website. On opening the contact on my desktop, I was surprised to see, I need to upgrade my account to view the contact. Doing some research along with my wife, I found this simple security vulnerability from LinkedIn that can let anyone view a contact’s full profile even when you have a “not upgraded” LinkedIn account and that the contact is a “3rd + Everyone Else”. Here’s an example of what I am talking about. I just made a random search on LinkedIn for a contact whose name starts with Sacha. Do note, this is just a walkthrough and I am not publicizing any Sacha. I check the “3rd + Everyone Else” and find a “LinkedIn Member”. On clicking this person’s profile to view, I am presented with the following page, asking me to upgrade. Make a note of this page’s web address and you get the profile id from it. For example, for this contact, the page address is: http://www.linkedin.com/profile/view?id=868XXX35 The Profile Id for this contact is 868XXX35. Now, open following page where the Profile Id is the same as the one we grabbed a moment earlier. https://touch.www.linkedin.com/?#profile/868XXX35 The mobile page exposes this contact information and you even get the possibility to connect to this person without an introduction mail (InMail). I hope someone from LinkedIn sees and issues a fix for this. I am pretty sure, it’s something that they don’t want the user to do without purchasing an upgrade package.

• DDD and Value Objects. Are mutable Value Objects a good candidate for Non Aggr. Root Entity?

  - by Tony

  Here is a little problem Have an entity, with a value object. Not a problem. I replace a value object for a new one, then nhibernate inserts the new value and orphan the old one, then deletes it. Ok, that's a problem. Insured is my entity in my domain. He has a collection of Addresses (value objects). One of the addresses is the MailingAddress. When we want to update the mailing address, let's say zipcode was wrong, following Mr. Evans doctrine, we must replace the old object for a new one since it's immutable (a value object right?). But we don't want to delete the row thou, because that address's PK is a FK in a MailingHistory table. So, following Mr. Evans doctrine, we are pretty much screwed here. Unless i make my addressses Entities, so i don't have to "replace" it, and simply update its zipcode member, like the old good days. What would you suggest me in this case? The way i see it, ValueObjects are only useful when you want to encapsulate a group of database table's columns (component in nhibernate). Everything that has a persistence id in the database, is better off to make it an Entity (not necessarily an aggregate root) so you can update its members without recreating the whole object graph, specially if that's a deep-nested object. Do you concur? Is it allowed by Mr. Evans to have a mutable value object? Or is a mutable value object a candidate for an Entity? Thanks

• Putting codes in email subjects

  - by Christian W

  We send out large quantities of email to our customers (work environment surveys). Sometimes our mailinglist for a client isn't quite up to date and we get bounce mails (address not found and such). However, since these all bounce back to the same address it's difficult to keep track on which bounce belongs to which client. (The email subject is usually pretty generic, like "Welcome to the work environment survey") This is why I would like to insert a identifier in the subject line of the email. So the subject would be "Welcome to the work environment survey (1234)" where 1234 is a number identifying the client/survey. We already rank pretty high because of the way our mailer handles sending the mails. Usually we contact the clients it-dept to get them to whitelist us in their firewall/spamfilter. Would this increase our spamscore in spamfilters?

• Ubuntu 10.10 forgets desktop theme.

  - by Marcelo Cantos

  (I posed this question on superuser.com and haven't received any answers or comments, then I came across this site, so my apologies to anyone who has seen this already.) I am running Ubuntu in VirtualBox (on a Windows 7 host). Several times now, the top-level menu bar, the task bar — and seemingly every system dialog — have forgotten the out-of-the-box "Ambiance" theme they conform to when I first installed the system. Window captions still preserve the theme, but pretty much nothing else does. I have searched high and low on Google for assistance with this problem. Everything I've found suggests either running some gconf reset or deleting .gconf* .gnome* and other similar directories. I have followed all this advice and nothing works. I still get a boring Windows-95-style gray 3D look and feel. On previous occasions, after much messing around I've given up and rebooted the VM instance, and been pleasantly suprised to see the original "Ambience" theme restored throughout the UI, but invariably it disappears again some time later, usually after a reboot, so I can never figure out what I did that broke it. Here's a sample from Ubuntu's site of what I want it to look like. And here's a screenshot of my system as it currently looks. Also note that my GNOME Terminals normally have a nice purple semi-translucent look, and as can be seen from the screenshot, they are now just a solid matt white. This last time (just yesterday), trying numerous combinations all the usual tricks and rebooting several times hasn't fixed it, so here I am on SU wondering: How do I recover the out-of-the-box theme for my Gnome/Ubuntu desktop, noting that blowing away all config files — as suggested in many places online — fails to achieve this? It might help to know that it seems to fail either after I resize the VM instance, forcing the Ubuntu desktop to resize itself, or after I play around with Compiz settings. I haven't been able to figure out which of these it is, and it could be neither. Given the amount of pain I have had to go through to get things back to normal (and given that I am at a loss as to how to do so), it has proven difficult to definitively isolate the cause.

• Correcting color-shifted mirrored i915 driver in 12.04?

  - by Will Martin

  I was called in to fix a friend's malfunctioning HP Pavilion. She's not sure exactly which model, but the sticker on the bottom says "G60". The problem was a failed upgrade to 12.04. I was able to mostly repair it with sudo apt-get -f install, which ran setup and configuration for several hundred packages. The biggest problem at the moment is Xorg. The login screen (lightdm) loads normally but at a reduced resolution (1024x768 instead of 1366x768). But once you log in, it looks like this: Observe that the colors of the dock on the left and the bar at the top are normal. But the background is filled with bizarro color-skewed ghost images of the desktop. In all cases, the actual contents of any programs you run is a totally illegible mess, except that the bar at the top of any program windows looks and acts normally. And the ghost images are interactive! For example, if you click the icon in the top right corner to get the "shut down" menu, the same menu will appear in the ghost images below. Starting a terminal will start a terminal window in both the real desktop and the ghost images, and moving it around updates both the real and ghost desktops. I suspect Xorg is using some kind of wrong driver and/or parameter for the graphics hardware. Here is the graphics-relevant portion of the lspci -v output: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information: Len=0a <?> Kernel driver in use: agpgart-intel 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at d0000000 (64-bit, non-prefetchable) [size=4M] Memory at c0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5110 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 3 Kernel driver in use: i915 Kernel modules: i915 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Memory at d2500000 (64-bit, non-prefetchable) [size=1M] Capabilities: [d0] Power Management version 3 I'm not sure what to check next. I would ordinarily check xorg.conf to see what it says, but that apparently doesn't exist any more, and my googling has not yielded any useful techniques for getting Xorg to tell me what settings it decided to use. The weird part is that it works fine on the login screen. It's only when you actually log in as a user that the display gets screwed up. Suggestions?

• How to configure remote access to multiple subnets behind a SonicWALL NSA 2400

  - by Kyle Noland

  I have a client that uses a SonicWALL NSA 2400 as their firewall. I need to setup a second LAN subnet for a handful of PC. Management has decided that there should be a second subnet even though intend to allow access across the two subnets - I know... I'm having trouble getting communication across the 2 subnets. I can ping each gateway, but I cannot ping or seem to route traffic fron subnet A to subnet B. Here is my current setup: X0 Interface: LAN zone with IP addres 192.168.1.1 X1 Interface: WAN zone with WAN IP address X2 Interface: LAN zone with IP address 192.168.75.1 I have configured ARP and routes for the secondar subnet (X2) according to this SonicWALL KB article: http://www.sonicwall.com/downloads/supporting_multiple_firewalled_subnets_on_sonicos_enhanced.pdf using "Example 1". At this point I don't minding if I have to throw the SonicWALL GVC software VPN client into the mix to make it work. It feel like I have an Access Rule issue, but for testing I made LAN LAN, WAN LAN and VPN LAN rules wide open with the same results.

• b Is it bad to have the Reverse DNS for two IPs point to the same domain name?

  - by Daniel Vandersluis

  I am in the process of setting up a new server for my web application (the site will be moved, it is not for load balancing or the like), which has a different IP address from my existing server. My current server has a reverse DNS PTR record set up pointing its IP to mydomain.com. Is it bad to set up a reverse DNS PTR record for the new IP pointing to mydomain.com as well? Or should I wait until I do my migration to set up the record? Update: I forgot to mention, the A record for the mydomain.com points to the old server's IP address, not the new one, if it matters.

In the second window. click on radio button "The server maintains the zone" and then click next. Give the zone name "example.com" Click on radio button, "Do Not allow dynamic updates". and then click next button. In the next window, click on radio button "No it should not forward query" and then click next button. Complete the configure a DNS server wizard and then click on finish button. After it is managing the DNS records: In DNS server wizard. open tree of forward lookup zone and right click on the new zone name "example.com" - properties and click on "Start of authority" and write values on text boxes serial number=1 primary server=systemname.domainname responsible person=hostmaster.domainname Click on server name, highlight domain name, click on edit button and enter IP address of the server where I host my application. Highlight new zone name and right click on it and click "New Host" option.

What mistake am I doing in this configuration?
