• Sending email with Windows 8 Mail (Modern UI) being blocked by AVG Firewall

  - by Riaan

  I've setup my Outlook.com email address in Windows 8 Mail (Modern UI) but is unable to send and receive emails when my AVG Internet Security 2012 Business Edition's Firewall is enable. When I disable the firewall, the emails are coming through and are being send. I know that I can most probably open the ports for IMAP on the firewall, but instead I would like to permit the application. Where/how do I find the application path for Windows 8 Mail (Modern UI) to allow all network traffic? (AVG did not show its normal Allow/Disallow notification for 1st time communications) Any advice would be appreciated.

• Chrome sending of packets to random destinations upon reconnect/disconnect

  - by f0x

  Noticed an interesting thing whilst debugging one of my websocket applications that Google Chrome will push out 3 http requests upon a network connection status changing; Quite disconcerting and looks almost as if some malware is checking out to a random server. I don't quite understand the why though since they all return a 502 or have no response code at all since the destination does not exist. On Disconnect: Reconnect: I guess the main question is this normal and what the use is; howcome they wouldn't go for a dns lookup that actually exists?

• Has anyone seen an HTTP 500 error when HTTPS traffic going through Pound Proxy forwards to an HTTP page?

  - by scientastic

  We have Varnish as our load balancer and reverse proxy cache for normal HTTP traffic. For HTTPS traffic, we use Pound proxy to unwrap the SSL and forward to Varnish, which then forwards to the back-end servers. This is used for our "checkout" process to encrypt credit card info in transition. However, on the last stage of checkout, users are always getting an HTTP 500 (Internal Server) error. It doesn't seem to be due to our back-end app server, by all tests I've tried. Does anyone know anything about how that transition works-- the transition back from HTTPS to HTTP and the interaction between Pound and Varnish-- and why it might cause 500 errors?

• Accessing a broken mdadm raid

  - by CarstenCarsten

  Hi! I used a western digital mybookworld (SOHO NAS storage using Linux) as backup for my Linux box. Suddenly, the mybookworld does not boot up any more. So I opened the box, removed the hard disk and put the hard disk into an external USB HDD case, and connected it to my Linux box.

And why there are 4 different partitions on it. fdisk showed the following: root@ubuntu:/home/ubuntu# fdisk /dev/sdc WARNING: DOS-compatible mode is deprecated.

Is there ANY way to see the contents of the largest partition? Or seeing somehow which files are broken? I see that everything is raid1 which is only mirroring, so this should be a normal partition. I am anxious to do anything with mdadm, in fear that I destroy the data on the hard disk. I would be very thankful for any help.

• Cannot access internal network on OSX 10.6.6

  - by cabuki

  Last week, I began having trouble connecting to our internal web servers. Usually, a refresh would take care of it or switching to a different wireless network, but as of yesterday, this wasn't enough. We have an internal DNS server using dnsmasq and a private internal host name (us.lcl). Once I started having more issues with the names not resolving, I tried pinging the server. Using the internal host name (s1.us.lcl), it failed. I tried using the IP address, but that also failed. I have no problems accessing external sites with the exception of it being a bit slower than normal. A reboot yesterday at lunch time after following the instructions here seemed to fix the issue, but when I came into the office this morning, it had stopped working. As of this posting, I cannot ping, ssh or access the web server using the internal host name or ip address. I'm the only one running 10.6 in my office and none of my colleagues has this issue.

• Windows: Create shortcut to changing folder name

  - by mikeparkie

  I have some portable apps and when I download them they extract to a normal directory structure, but the structure includes a version number, How do I create a start-up shortcut to the program so it doesn’t break when the application is updated? For example: I can create a shortcut to “D:\PortableApp\V1\prog.exe” and place the shortcut into Startup items and it works fine. Now the program is updated to V1.1. How do I get the shortcut to update to “D:\PortableApp\V1.1\prog.exe”without manually updating the shortcut? Thanks in advance mikeparkie

• svnserve, Mac OS X Lion Server and user accounts

  - by Casper

  I am trying to use the "built-in" user accounts of my Mac OS X Lion server to grant access to repositories. Currently I am using the conf/passwd file (which works), but I don't like the fact that the passwords are visible as plain text. Is there a way to "connect" the svnserve access restriction to the normal user accounts that are already on the system? Thanks PS: I am not wanting to connect via Apache/WebDav - there I know it works. I want to connect via svn:// using the existing user accounts.

• VLC Caching levels

  - by Svish

  When I open the Preferences of VLC and go to Input & Codecs, I have a setting called Default Caching Level. I can choose between Cusom Lowest latency Low latency Normal High latency Higher latency I'm used to caching being set in seconds or something like that. So, more seconds/higher buffer means less chane of buffer underrun while streaming. What is latency? What does it mean to set it lower or higher? In what cases should I go in what direction? If I'm struggling with buffer underruns, should I set it to lower or higher latency?

• Solaris NFS: user permissions

  - by cjavapro

  I am very new to NFS. I would like to make sure I am clear. If the NFS server shares a directory rw,, and all the files in the directory are permissions 700 and user/group for those files is root/root,,, On the client you would have to log in as root to see it. Is this correct? I am aware that a non root user on the client could make a direct connection to override this. (as in don't use the mount, just use an NFS client hack.) It really seems like anyone who has access to the client machine should have access to the files and that the client machine should be ignoring permissions. Only the server should handle permissions. Am I correct in my understanding? Is it normal to have this type of layout? Is there a way to ignore the permissions on the client side?

• Remote Desktop AND monitor fail on restart (Win2008R2)

  - by Wesley

  I am in the process of building a small 3 server farm. Each machine is running Window Server 2008 R2. As is normal, I am in the process of installing patch after patch to bring the machine up to snuff. Every time I restart the machine, or most every time, when I try to remote in to the machine I get the Log In window, but then almost immediately I get the message that my remote session was ended. If I physically walk over to the machine and plug in a monitor and keyboard, I see nothing. If I leave the keyboard and monitor in and restart the machine by force, the computer reboots just fine. When windows starts, I get no error message about windows not starting or being shut off unexpectedly. Once I log into the machine physically by the keyboard, I can then remote in to the machine at that point. Very confused. This happens on all 3 machines, these machines have different hardware.

• Computer won't stay powered up

  - by Android

  I have just tried to turn my PC on this morning and it won't stay powered up. It will come on as normal for about 5 seconds, not quite long enough for the monitor to wake up. Then it will power off. After about 2 seconds it will start again, it will continue like this until I pull out the plug. Plugging it in again doesn't restart the cycle although pressing the power button does. I have tried to clear the cmos but beyond that I have no ideas. It was working perfectly when I put it in hibernate last night. NOTE: I am using a Dell Optiplex 755 UPDATE 1: I took out the motherboard battery and it almost came on then it displays the message Error loading Operating System UPDATE 2: After taking out the custom video card, it says "No hard drive present"

• How to prevent Windows 8 of erasing GRUB?

  - by dirleyrls

  I'm doing dualboot with Ubuntu and Windows 8 on my DELL Laptop. EFI is enabled, secure boot is not. My partitions are GPT. Everything seems to work for some time. After some normal use, GRUB stops working. The "ubuntu" EFI entry is still there on top of everything else. But the computer boots directly into the Windows Bootloader, skipping GRUB. Any clues on why is that happening or how can I prevent that? My current partiton setup is: - /dev/sda1 NTFS Windows recovery - /dev/sda2 FAT32 UEFI boot (with boot flag) - /dev/sda3 unknown (msftres flag) - /dev/sda4 NTFS Windows Drive C - /dev/sda5 ext4 /home - /dev/sda6 ext4 / I usually reinstall GRUB through chrooting from a Live Session and doing a apt-get install --reinstall grub-efi-amd64.

• Word 2010 Style Sets and Multilevel Lists

  - by Stevia

  In Word 2010, how can you create quick style sets that include multilevel lists (include being the operative word)? As background, I have created a set of styles for a long agreement form and assigned them to levels in a certain custom multilevel list. I then also saved those styles as a quick style set called Long Agreement. I have saved those styles in my normal template. That all works fine for assigning styles to a Long Agreement. What I'd like to do next is create a second style set called Short Agreement. I will assign certain styles to that style set. The issue is that I don't see how to tie a different custom multilevel list to those Short Agreement styles. When I click on Change Styles, Short Agreement [style set], and I apply those styles, how can I get it to automatically use the multilevel list that I assign to short agreements?

• Network flooded with seemingly empty packets

  - by Adam Particka

  Let me preface this with the fact that I'm just a web developer at my company with little networking knowledge. Earlier today there was a department that lost all of their network connections so I popped open Wireshark and observed the influx of packets to my machine. There was normal traffic (ARP requests, etc.) coming in at ~50 packets every second. Then all of a sudden the log was flooded with packets arriving ~5000 a second. It looks as though they all contain the same data, just a looped sequence. We have someone here looking at it but I thought I would ask if anyone had seen anything like this before. Here's a selection from one of the captures in Wireshark. http://www.cloudshark.org/captures/06f950725c74

• Why might one hard disk perform slower than another?

  - by Styne666

  I have just bought two WD 3TB Reds (WD30EFRX) for a FreeNAS box and whilst doing burn-in testing it seems like one is consistently taking about 10% longer than the other. So far I've done: a dd read test of the whole device, a long SMART test and it's currently halfway through a badblocks -wvs. The second device is lagging behind the first on all of them. I'm running these commands on Debian stable in two Konsole tabs. Is there a reason this could be considered normal behaviour or is it worth running the tests independantly? They're both plugged in to the LSI 2308 (IT mode) on a Supermicro X10SL7-F.

• SSH logins failing before success

  - by Vincent

  I am running Ubuntu 12.04 Server, updated, to run a webserver on Tomcat 7. I have about 1000 clients that are very very often using an RSYNC program to sync some file with this server. Those RSync are using SSH with a certain user to open connections on the server. The result is that my server is, as normal, full of connections by the same user. About 5 connections per 1 second every day any time. Then, when I try to open a regular SSH connection with my Putty client, the connection fails before login saying "Server unexpectedly closed network connection", about 6 times for 10 attemps, anbd for 4 attemps out of 10, it works normally and I am able to login as any user. Is there a overload of connections here? The server statistics are very calm saying less then 40% of network usage and less of 2% CPU. How can I improve this? Thank you for any help. V.

• Why Virtualbox VDI doubles the space of the VM hard disk?

  - by logoff

  I have one Xubuntu 12.10 64 bit Virtualbox VM on a Windows 7 64 bit host. It has one dynamic allocated hard disk with VDI format with maximum capacity of 20GB. If I use a command df -h in the VM I get that 5.3GB are in use in th main partition. I have only 2 partitions, one for the ext4 hard disk and another with 512MB of swap. I have no snapshots. The VDI file of this VM has 10.7GB. It is normal this difference of space? It is caused because the VDI format?

• How to copy a button with shadow effect from PSD to PNG

  - by Alex

  I got a web site design in PSD file from a web-designer. All element s there snap to guides, which is handy when I make a selection to copy an element of design to a PNG file: guides make my selection precise. One button there has two states: normal and hover. Both states contains of several layers. So I am trying to copy both states as PNG files in order to make a nice button in html. The problem is that both states have shadow effects, which go beyond the layers' edges, i.e. when I try to select a button my selection (snapped to guides) does not include an outer part of the shadow. How do I make a precise selection of the button state in such situation?

• Dual monitors on Windows - How do I set a different DPI or text size on each monitor?

  - by dlux

  My laptop is a 15" wide screen running at 1600x1050, and in addition to that I connect an external 19" LCD which runs at 1280x1024. The problem with this setup is that if I increase the text size to make the laptop screen readable, the text on the external LCD is huge. Normal text on the LCD results in tiny text on the laptop. What options do I have to get around this? I'm using Windows 7 and the laptop is a ThinkPad T61 with an nVidia NVS 140M video chipset. I cannot find any per-display setting in Windows or the nVidia control panel to resolve this.

• Windows XP - Website unaccessible on single pc in LAN

  - by DorentuZ

  For serveral days now, a website isn't accessible on a single pc in the LAN. On the other pc's, it works just fine. And it's just a single website that's not accessible as far as I know of. The website generates a timeout on every single web browser I've tried (IE8, Firefox and Chrome). However, traceroute, nmap and telnet all work just fine. I've even tried multiple user accounts and safe mode, but that didn't work either. As a side note: using a linux live cd did work and I could access the website without any problems. The hosts file is the windows default, the ip- and dns settings on the network adapter normal as well. No strange processes are running and no viruses found. According to tcpview and netstat there are connections to the domain, but every request in the browser results in a timeout.. Any idea what's happening?

• Windows XP occasionally hangs for 2-3 minutes as the splash screen fades in.

  - by marcusw

  This is a bit of a rare problem, I have not been able to debug or fix it or find anyone else with the issue. I hope someone here can help me out. Once in a while, I boot up Windows XP from the first partition of the first disk (using grub, the computer dual-boots ubuntu) and it hangs as the Windows XP splash image fades in, leaving the screen with a dim image of the splash screen. After 2-3 minutes, it continues to boot as normal, no error messages or strange behavior. I have noticed that this happens about 75% of the time when the last time the computer was shut down it was from Ubuntu, and maybe 5-10% of the time otherwise. I have looked at system logs as far as I was able, and did not find anything the miss. What is causing this and how can I fix it?

• Can someone please explain these Network Activity entries are? (resource monitor windows 7)

  - by Keyes

  The first one is the address microsoftword.com.br. What is this? I noticed when I connected windows to the internet briefly, and it went away soon after. when I typed the address into my tablet, it redirected to bing with the search "microsoftword com" with MSSRPD at the end of the address. The other unknowns seemed to appear when my brothers laptop was connected to the network. Is that normal? Usually if I disconnected and reconnected they would appear, but I noticed when I had disconnected and reconnected to try it didn't happen as he wasn't connected. I'm concerned about the microsoftword one is. Is it legitimate? The svchost that associated with is a legit svchost image.

• Setup non-MS email (gmail) in Windows 8 Mail app

  - by CoolUserName

  All documentation I have found online seems to apply to an older or different version of Windows 8. I am using the 90 evaluation copy of Windows 8 Enterprise (http://msdn.microsoft.com/en-us/evalcenter/jj554510.aspx). Is it disabled because it is enterprise edition? Basically, I can start the mail app, bring up the settings (windows+i), but all I am given for options are Permissions and Rate and Review. In other documentation I've seen this is where you add an account. Is this possible? If this is a restriction to Windows 8 Enterprise, is there a trial version of normal Home editions somewhere?

• Windows 8 apps not connecting to internet with USB dongle/modem

  - by Relborg

  The question pretty much says it all. I have Windows 8 Professional 64-bit and my main/only method of getting connected to the internet is to use this USB dongle/modem I have. Now it works perfectly, but when I go into the Windows "store" app it keeps on saying that I'm not connected to the web. In fact this happens for all "apps", they all think I'm not connected to the web when I actually am. Normal desktop applications e.g. browsers run fine. Is this a bug that has still not been resolved or is there some setting I need to go mess with? Thanks in advance!
