• How can I install .NET framework 3.5 on XP machines without internet connection?

  - by EricSchaefer

  I want to install .NET framework 3.5 on a couple of machines that do not have internet access. If I install the "no internet access"-package it still wants to download something. How can I figure out what is missing? Are there other installation packages? Edit: I would present screenshots but I cannot upload anything from here and the shots would be in german. So I present only the text translated back to english... Installing the "full redistributable package": At the bottom of the license agreement page it display this text: Size of download file: 67 MB Appoximate download time: 2h 44min (56KBit/s) 18min (512KBit/s) It shows the text even if I installed Windows Installer 3.1. After agreeing it displays the "Download and Installation Status"-Dialog with a progress bar labeled "Download:" and Status: Connection to server attempted (try X of 5). Total Download Status: 56MB/67MB I tried it in a VM with no network connection. It tries 5 times while the progress bar shows progress. Later the progress bar is labeled "Installation:". Even later it reports problems during setup and provides two buttons "Send Report Later" and "Don't Send". Now here it comes: "Setup completed" and "Microsoft .NET Framework 3.5 has been deinstalled successfully." (Emphasis is mine) "It is recommended to install current service packs and security updates. More information at Windows Update (link)." Edit2: Installed Service Pack 3, but still no success.

• Is there a utility to visualise / isolate and watch application calls

  - by MyStream

  Note: I'm not sure what to search for so guidance on that may be just as valuable as an answer. I'm looking for a way to visually compare activity of two applications (in this case a webserver with php communicating with the system or mysql or network devices, etc) such that I can compare the performance at a glance. I know there are tools to generate data dumps from benchmarks for apache and some available for php for tracing that you can dump and analyse but what I'm looking for is something that can report performance metrics visually from data on calls (what called what, how long did it take, how much memory did it consume, how can that be represented visually in a call stack) and present it graphically as if it were a topology or layered visual with different elements of system calls occupying different layers. A typical visual may consist of (e.g. using swim diagrams as just one analogy): Network (details here relevant to network diagnostics) | ^ back out v | Linux (details here related to firewall/routing diagnostics) ^ back to network | | V ^ back to system Apache (details here related to web request) | | ^ response to V | apache PHP (etc) PHP---------->other accesses to php files/resources----- | ^ v | MySQL (total time) MySQL | ^ V | Each call listed + time + tables hit/record returned My aim would be to be able to 'inspect' a request/range of requests over a period of time to see what constituted the activity at that point in time and trace it from beginning to end as a diagnostic tool. Is there any such work in this direction? I realise it would be intensive on the server, but the intention is to benchmark and analyse processes against each other for both educational and professional reasons and a visual aid is a great eye-opener compared to raw statistics or dozens of discrete activity vs time graphs. It's hard to show the full cycle. Any pointers welcome. Thanks!

• McAfee ePolicy-Orchestrator (ePO) - policy ownership by groups?

  - by bkr

  Is there a way to grant ownership of an ePO policy to a group? Alternatively, is there a permission that can be set that would allow owners of an ePO policy to add other owners to that policy without making them ePO admin? In the case I'm looking at, ePO is deployed within a large heterogeneous organization with a large amount of delegation in the form of create/modify policy rights to allow multiple IT departments to customize to their needs for their sections of the system tree. The problem is that the policies are owned by the creator of the policy. This causes problems when they leave (staff turnover) or when other people on their teams need the ability to modify the existing policy. Unfortunately, as far as I can see, only someone who is an ePO admin can change the owners. Even the owner of the policy cannot add other owners (unless they are also an ePO admin). Ideally, I should be able to assign ownership of a policy to a group - since that would be easier to manage than me or another admin having to continually fix policy ownership or remove orphaned polices. Even just allowing the owners of the polices to add other owners would be sufficient. How are other people handling policy ownership when dealing with a large amount of delegated control of polices? Is there a way to delegate this out without making users full ePO admins?

• How to access original files from before a symlink gets updated, which have since been moved to another dir

  - by Luke Cousins

  We have a website and our deployment process goes somewhat like the following (with lots of irrelevant steps excluded) echo "Remove previous, if it exists, we don't need that anymore" rm -rf /home/[XXX]/php_code/previous echo "Create the current dir if it doesn't exist (just in case this is the first deploy to this server)" mkdir -p /home/[XXX]/php_code/current echo "Create the var_www dir if it doesn't exist (just in case this is the first deploy to this server)" mkdir -p /home/[XXX]/var_www echo "Copy current to previous so we can use temporarily" cp -R /home/[XXX]/php_code/current/* /home/[XXX]/php_code/previous/ echo "Atomically swap the symbolic link to use previous instead of current" ln -s /home/[XXX]/php_code/previous /home/[XXX]/var_www/live_tmp && mv -Tf /home/[XXX]/var_www/live_tmp /home/[XXX]/var_www/live # Rsync latest code into the current dir, code not shown here echo "Atomically swap the symbolic link to use current instead of previous" ln -s /home/[XXX]/php_code/current /home/[XXX]/var_www/live_tmp && mv -Tf /home/[XXX]/var_www/live_tmp /home/[XXX]/var_www/live The problem we are having and would like help with is that, the first thing any website page load does is work out the base dir of the application and define it as a constant (we use PHP). If then during that page load a deployment occurs, the system tries to include() a file using the original full path and will get the new version of that file. We need it to get the old one from the old dir which has now moved as in: System starts page load and determines SYSTEM_ROOT_PATH constant to be /home/[XXX]/var_www/live or by using PHP's realpath() it could be /home/[XXX]/php_code/current. Symlink for /home/[XXX]/var_www/live get updated to point to /home/[XXX]/php_code/previous instead of /home/[XXX]/php_code/current where it did originally. System tries to load /home/[XXX]/var_www/live/something.php and gets /home/[XXX]/php_code/current/something.php instead of /home/[XXX]/php_code/previous/something.php I'm sorry if that is not explained very well. I'd really appreciate some ideas on how to get around this problem if someone can. Thank you.

• "Ethernet" doesn't have a valid IP configuration

  - by Xuzuno

  I'm using an ethernet cord to connect to my internet and it has been working well until Thursday morning when I turned on my laptop (Windows 8) to see a yellow triangle sign in the bottom right hand corner, in front of the ethernet connected symbol. Since then I haven't been able been able to access the internet from my computer. When I hover over it, it says that it is an "Unidentified network" and there is "No internet access". I've run the Windows 8 troubleshooting and it says that the problem found was ""Ethernet" doesn't have a valid IP configuration", but I'm unsure how to fix it. I'm thinking that the problem is to do with my computer rather than my network, because I've tried another laptop (Windows 7) through the same ethernet cable and connection and the internet works fine on the other laptop. I've tried so many fixes that I've found online, with none of them actually working. Yesterday I even tried a full system reset, where I re-installed Windows 8, re-partitioned and wiped everything off the hard drive, but it still appears have the exact same problem. Today I also purchased and tried a new ethernet cable which didn't work, so I then purchased a USB to Ethernet adapter, to make sure that it wasn't my ethernet port on my laptop that was faulty. That didn't work either, and the same problem still remains. I feel like I've tried everything, so can someone please help me?

• Computer randomly shuts itself off

  - by Decency

  I have not been able to determine a pattern for why this happens, despite my best efforts. I've attempted to run it on full power with Prime95 and this doesn't trigger a restart. Generally the restarts occur while I'm playing games, watching videos, or even just having multiple tabs open in a browser. However, I often play processor intense games for hours without any restarts occurring, and sometimes they'll happen 3-4 times in an hour during less intense activity, so I don't think that is the problem. I imagine it has something to do with overheating or power consumption so I've been monitoring CPU temperature and cleaning with compressed air, but the problem keeps happening. I don't know how to track power consumption, and assume that this is the problem. Whenever this occurs, the sound gets stuck in a short loop of whatever was playing at the time, though restarts also occur when nothing is playing. Here is a screenshot of temperatures: and under load: Here's the parts list: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10546754 As shown in the list, the case includes a 585W Power Supply, which I've been told should be plenty. I built the computer myself with a friend's guidance but it's very possible I did something wrong. Right now I'm looking into ensuring that I have the latest drivers for all components. Any help would be appreciated- thanks.

• 403 Forbidden serving static files from VirtualBox shared folder with nginx (Ubuntu 10.04LTS guest, Windows 7 host)

  - by Chris Pratt

  I'm working on a local development VM and trying to test serving my site with gunicorn and nginx as a reverse proxy for static resources only. The site loads minus static resources with user nginx; in nginx.conf. Attempting to load a static resource individually reveals a 403 Forbidden error. For background. The static resources are in a shared folder under /media/sf_work. All files are owned by root:vboxsf (VirtualBox default). My user account on the system has been added to the vboxsf group, and I have full access to the shared folder. For comparison, I tried changing the nginx.conf user to my user account. In that scenario, the static files did load, but then the homepage itself gives a 403 Forbidden error. So, I then tried adding the nginx user to the vboxsf group, but then everything gives a 403 Forbidden error. After further investigation it seems that if the nginx.conf user is in any group, it results in a 403 Forbidden. Any idea what could possibly be going on here?

• Drowning in documents - recommend doc management solutions?

  - by Martin Day

  I've been researching document management lately. I want to organise my docs at home and also at the office. Finding affordable solutions one can actually test drive is quite hard. Some that I've downloaded just don't seem to work (testing on brand new Vista PC). I've seen some software on Amazon like Paperport but not really sure what they're like. For home I'd like something to organise files, full text search, good scanner integration, nice interface etc. But for the office it seems harder. I need something that does proper workflow and keeps versions. It will have an audit trail. Documents can be approved, checked in/out etc. I know a few clients who would like something similar. It would be great just to import thousands of documents from a shared drive and get them indexed with dupes killed. I'd like to be super clear about how/where the documents are being stored so that maintenance and backups are clear. My Google/twitter searches lead back to the same tired and vague webpages pushing what look like expensive and custom made solutions. Some might be very good I suppose but it's darn hard to tell. I don't mind a hosted package but all in all I don't think something like Google Docs, as good as it is now, will work. There are too many quirks and missing features (as compared to Office). Being able to work directly with the common Office file formats is important. I've noted a similar sounding question asked here back in August but it didn't seem to turn up too many solutions that I could easily and quickly apply. Also there could have been some changes since then so I feel it's worth asking.

• External Dell Display doesn't work with MacBook Pro (2011) after Thunderbolt Firmware Update (1.0 and 1.2)

  - by tom

  Today two Thunderbolt Firmware Updates (1.0 and 1.2) became available for my MacBook Pro (Early 2011). After installing both, my external monitor, a Dell U2713HM, does no longer work. The system detects the display, but the display shows only black. An Apple Thunderbolt display works fine and a MacBook Air can use the Dell monitor without problems. My MacBook Pro can use the Dell monitor just fine when I boot from a USB stick. Therefore, clearly the Thunderbolt Firmware Update seems to be the problem. Does anyone have the same problem? Any solutions or workarounds? I guess there is no way to remove a Thunderbolt Firmware Update once it's installed, right? Update 24.10.2013: Is there no one else with this problem? In the meantime I tried three different cables – none worked. My colleague with the same generation MacBook Pro also can't use my display after installing the firmware update. All colleagues with MacBook Airs and newer MacBook Pros (all didn't receive the firmware update) can use the display. Update 29.10.2013: Wow, ok today my new MacBook Pro Retina 13' (Late 2013) arrived. Guess what, I cannot use the display with it. Only HDMI works – not with the full resolution.

• Can we do a DNSSEC 101? [closed]

  - by PAStheLoD

  Please share your opinions, FAQs, HOWTOs, best practices (or links to the one you think is the best) and your fears and thoughts about the whole migration (or should I just call it a new piece of tech?). Is DNSSEC just for DNS providers (name server operators)? What ought John Doe to do, who hosts johndoe.com at some random provider (GoDaddy, DreamHost and such)? Also, what if the provider's name server doesn't do automatic signing magic, can John do it manually? In a fire-and-forget way, without touching KSKs and ZSKs rollovers and updating and headaches?) Does it bring any change regarding CERT records? Do browsers support it? How come it became so complex? Why didn't they just merged it with SSL? DKIM is pretty straightforward, IANA/IETF could've opted for something like that. (Yes I know that creating a trust anchor would be still problematic, but browsers are already full of CA certs. So, they could've just let anyone get a cert for a domain for shiny green padlocks, or just generate one for a poor blue lock, put it into a TXT record, encrypt the other records and let the parent zone sign the whole for you with its cert.) Thanks! And for disclosure (it seemed like the customary thing to do around here), I've asked the same on the netsec subreddit.

• Win 7 Remote Desktop connection failure when already logged in.

  - by Andy E

  I have a bit of a strange problem, magnified recently by my broadband dropouts. I wasn't sure whether to post this on SU or SF, so I thought I'd start here as more users would be likely to know what the problem is. In short, when I try and connect to my server (Windows Server 2008) from my laptop running Windows 7, I can only connect if my remote account was previously logged out. If I'm still logged in I get the error message: Windows cannot connect to the remote server. No explanation or anything. If my IP address is the same, I don't have this problem. If I boot up Windows XP Mode and run XP's remote desktop connection it works just fine -- I think the difference there is it takes me to the remote server's logon screen. With Win 7 RDC you never see the logon screen, it asks you for credentials before entering full screen mode. The real problem is that I'm having random broadband dropouts and my IP isn't static. If I logon via Win XP RDC, log out and then run Win 7 RDC then it works fine. I realize I can just use Win XP's RDC for now, but I don't really like keeping XP Mode open if I can help it. Does anyone know a way around this problem? Maybe forcing Win 7 RDC to go to the logon screen, or changing some server-side settings to work around the IP address issue?

• Jailkit not locking down SFTP, working for SSH

  - by doublesharp

  I installed jailkit on my CentOS 5.8 server, and configured it according to the online guides that I found. These are the commands that were executed as root: mkdir /var/jail jk_init -j /var/jail extshellplusnet jk_init -j /var/jail sftp adduser testuser; passwd testuser jk_jailuser -j /var/jail testuser I then edited /var/jail/etc/passwd to change the login shell for testuser to be /bin/bash to give them access to a full bash shell via SSH. Next I edited /var/jail/etc/jailkit/jk_lsh.ini to look like the following (not sure if this is correct) [testuser] paths= /usr/bin, /usr/lib/ executables= /usr/bin/scp, /usr/lib/openssh/sftp-server, /usr/bin/sftp The testuser is able to connect via SSH and is limited to only view the chroot jail directory, and is also able to log in via SFTP, however the entire file system is visible and can be traversed. SSH Output: > ssh testuser@server Password: Last login: Sat Oct 20 03:26:19 2012 from x.x.x.x bash-3.2$ pwd /home/testuser SFTP Output: > sftp testuser@server Password: Connected to server. sftp> pwd Remote working directory: /var/jail/home/testuser What can be done to lock down SFTP access to the jail? FWIW, I mostly used this as a guide: http://digitalpatch.blogspot.com.ar/2010/03/openssh-daemon-hardening-part-3-setup.html

• Can a OS be copied from one hard drive to another and still boot?

  - by AlexMorley-Finch

  Background My computer gets stuck on the make and model screen after the BIOS screen, aka the Toshiba screen. After some research I've realized that the problem is the hard drive. I'm using an old 250gb model that USED to be used for backup purposes, however I loaded windows 7 ultimate onto it This hard drive has trouble getting up to full RPM therefore cannot boot correctly until its warmed up. meaning that my pc needs to be restarted several times before it boots (once it took my 13 reboots to get my pc on!) From my research its either that, or lack of power supply, and I've tried multiple PSUs. Question I have my OS and all my files on this 250gb HDD... If I were to literally open the explorer, and copy EVERYTHING (including hidden files obviously) from this 250gb, to a spare 500gb I've got knocking about... Will it boot if I just copy everything? I cannot be bothered to load another OS onto my PC so if there is a way I can just copy the existing one over from one HDD to another and have it boot normally. This would be epic! I've heard about HDD cloning software. But before I purchase and/or download this software, I need to know if i can just copy the OS over through the windows explorer

• Recover file from NTFS after it was formatted twice

  - by Phil

  I'm running Linux Mint and have a 2TB drive that I formatted as NTFS. I copied ~120GB of files from another computer to the 2TB drive, removing the files from the other computer as I did so. When they were all on the 2TB drive, I zipped them up as file "Gold.tar.gz". Then I reformatted the 2TB drive as ext3 in a moment of absolute stupidity. I formatted the 2TB back to NTFS, but of course everything is gone. Here is what I have tried: TestDisk -- won't find any lost partitions or undelete files, just the current empty one PhotoRec -- seems to only find some broken text files and misidentify their extensions. It never finds the 100's of avi files I had (before the 120GB copy, I already had 750GB on the drive full of avi files) or anything else that would show me it's working properly. Using dd I recovered the first 512MB of the drive and went hunting through it. I found all of the file as MFT entries, including the file "Gold.tar.gz" in a 2048 byte MFT record. I'm looking now for some way of either (1) telling PhotoRec to look at that record, or (2) analyze the MFT record myself and discover the sectors holding the data; I can piece it all together using dd and join the binary output if it's fragmented. One last thing - from the moment I got this drive a few days ago to the incident, there were only file copies made to it and no deletes. I formatted as NTFS, then copied thousands of files, then made a tar.gz, then reformatted to ext3, then reformatted to NTFS again. I'm hoping that the size of the drive and fact that there was no file modification/deleting happening makes for minimal file fragmentation.

• Why can't a PC with 2 network cards be accessed by hostname?

  - by lewis

  I set up PC with 2 network cards, connected to the same LAN. I can connect to this PC (e.g. by remote desktop) only via ip-addresses. Accessing by hostname does not work. Why is this the case? UPDATE: Full environment 1. PC with 2 hardware network adapters. 2. On this PC installed VMWare Workstation. Created 3 VM's, networked by "bridged" network setting in VMWare. 3. In LAN all ip-addresses given from DHCP. 4. Win2k8 on all hosts (both physical and vitrual). As result: 1. PC has 2 ip-address (e.g. 192.168.1.71 and 192.168.1.72). PC available in LAN by ip-addreses, but not avail by hostname. 2. VM's has own ip-addr on each (e.g. 192.168.1.73, *74, *75 etc). They are available from LAN by their ip's, BUT not by their hostnames. How can I access to PC and to VM's by hostname?

• What user information is exposed via a browser?

  - by ipso

  Is there a function or website that can collect and display ALL of the user information that can be obtained via a browser? Background: This of course does not account for the significant cross-reference abilities of large corporations to collate multiple sources and signals from users across various properties, but it's a first step. Ghostery is just a great idea; to show people all of the surreptitious scripts that run on any given website. But what information is available – what is the total set of values stored – that those scripts can collect from? If you login to a search engine and stay logged in but leave their tab, is that company still collecting your webpage viewing and activity from other tabs? Can past or future inputs to pages be captured – say comments on another website? What types of activities are stored as variables in the browser app that can be collected? This is surely a highly complex question, given to countless user scenarios – but my whole point is to be able to cut through all that – and just show the total set of data available at any given point in time. Then you can A/B test and see what is available with in a fresh session with one tab open vs. the same webpage but with 12 tabs open, and a full day of history to boot. (Latest Firefox & Chrome – on Win7, Win8 or Mint13 – although I'd like to think that won't make too much of a difference. Make assumptions. Simple is better.)

• Managed LAMP platform for maximizing availability and global reach, not scalability

  - by user66819

  Assume a Linux/Apache/MySQL/PHP application for a small base of registered users. With small userbase, there are no traffic peaks so the scalability that cloud platforms offer is not imperative. But the system is mission-critical, so availability is the primary goal. Users are also distributed across Asia, Europe, and US, so multiple server locations that minimize users' network hops would be highly desirable. The dream: a managed VPS platform where we would configure a single server (uploading PHP and other files, manipulating database, etc.), and the platform would automatically mirror the server in a handful of key places around the world (say one on each US coast, one in Europe, one in east Asia). File system synchronization and MySQL replication would happen automatically. Core operating system is managed, so we don't need to do full system administration and security, and low-level backups are also done by service provider, though we also do our own backups as well. Couple this with some sort of DNS geo-detection, so users are routed to the nearest operational server... with support for https, of course. Does such a dream exist? If not, what are some approaches to accomplish the same end with minimal time investment and minimal monthly hosting costs?

• ASUS laptop doesn't charge/use the battery after reinstalling Windows 7

  - by Stan

  I've done a clean install of Windows 7 x64 on an ASUS X501A laptop. The battery is detected and shows in the system tray as "plugged in, charging". However the charge level stays at 76% and if the AC cord is plugged out the laptop turns off. The laptop does not turn on without being plugged in either. Everything worked perfectly prior to reinstall. I've tried: Downloading and installing all the ASUS drivers, including the ATK ACPI driver Checking the BIOS - there do not seem to be any battery-related settings Flashing the BIOS to the latest version Uninstalling Microsoft ACPI-Compliant Control Method Battery in device manager as suggested on the internet Full power discharge/ATX reset as suggested by ASUS support: remove mains power charger, remove battery, press and hold power button for 10 seconds, reconnect battery and mains and turn on I have a feeling all this may have something to do with the EFI BIOS that comes on the laptop. During the reinstall I had to delete all partitions and start anew, because the Windows installer complained about the improper order of GPT partitions. The EFI System Partition was recreated by the installer, and I am guessing that it may be missing the particular ACPI driver needed to make the battery work. I've tried researching this, but could not come up with any useful info. I am hoping someone here may know a bit more about this and maybe help me understand what's going on and how to fix it. Barring that, I'll have to re-image the drive off an identical ASUS laptop with stock install and hope it fixes things.

• Transferring domain from one registrar to another

  - by Macha

  I have a domain from my old web host, which was free with my hosting account. After a few years, I am moving to a VPS. Most of my other domains were registered with Namecheap, so it was just a matter of changing a few DNS records. However, given that my old host does not provide me with a DNS control panel, and I don't want to be paying a full hosting bill for just domains, I'm now looking into transferring it. My old host says there will be a charge of $15 to them. NameCheap's page seems to imply you don't need the current registrar to do anything, but it also seems to be based on sending an email to the one listed in whois. Of course, my old host have whoisguard on the domain so the only email on it is [email protected] (and not a unique [email protected], just [email protected]) which doesn't go to me. Again, there doesn't seem to be an option to disable this. So, is it a case of paying my old host's fee, and paying again for the domain from NameCheap, or is there some other way to transfer my domain? (I'm not really sure which of the trilogy sites this is best for.)

• windows xp cannot access admin share

  - by barlop

  I have 3 systems. A,B,Compx all on xp. but comps A and B have an issue with Compx. Compx has network shares I can access. I can do \\compx and get some. But I cannot access the admin share c$ \\compx\c$ gives a login prompt, and I can't get any user/pass to work. I looked at permissions but don't see an issue. Nevertheless, I will describe what I see in the permissions. In the security tab of C, I have Administrators,creator owner,everyone,bob,system,users (6 things there) "creator owner" has nothing ticked, I can't seem to change that. If I tick so they all get ticked, and click apply, 2.5min and it's completed its opration and they all untick. Though this isn't the root of the problem. Since I get the same in the share I can access. In advanced, I see those 6 things, Administrators,creator owner,everyone,bob,system,users (6 things there) all "full control" all are "this folder, subfolders and files".. except creator owner, which is just subfolders and files only I look at the properties for the share I can see. looks the same, except in security..advanced, double clicking any of them the boxes are all ticked but greyed. That's not the problem though since I can access that share. So, I don't know what the problem is.

• Libvirt/KVM in NAT: can't access from host (and can't forward)

  - by SharkWipf

  I'm trying to set up a port forward to a KVM guest, managed through Libvirt on Debian 6. The VM is running in NAT, through the "default" network. This all runs fine, the VM has full internet connection. However, the host cannot reach the vm internally. Neither ping, nc nor nmap on the NAT network give any signs of the VM. Due to this, the normal iptables forwarding rules don't work either. $ cat /etc/debian_version 6.0.5 $ libvirtd --version libvirtd (libvirt) 0.9.11.3 $ kvm --version QEMU emulator version 1.0 (qemu-kvm-1.0+dfsg-11, Debian), Copyright (c) 2003-2008 Fabrice Bellard ifconfig: eth0 Link encap:Ethernet HWaddr 54:04:a6:f1:6f:10 inet addr:x.x.x.x Bcast:x.x.x.x Mask:255.255.255.x inet6 addr: fe80::5604:a6ff:fef1:6f10/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:118902 errors:0 dropped:0 overruns:0 frame:0 TX packets:142357 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13247173 (12.6 MiB) TX bytes:95163190 (90.7 MiB) Interrupt:28 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:230646 errors:0 dropped:0 overruns:0 frame:0 TX packets:230646 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:204577107 (195.0 MiB) TX bytes:204577107 (195.0 MiB) virbr0 Link encap:Ethernet HWaddr fe:54:00:e2:d2:60 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5050 errors:0 dropped:0 overruns:0 frame:0 TX packets:961 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:666759 (651.1 KiB) TX bytes:400701 (391.3 KiB) vnet0 Link encap:Ethernet HWaddr fe:54:00:e2:d2:60 inet6 addr: fe80::fc54:ff:fee2:d260/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5050 errors:0 dropped:0 overruns:0 frame:0 TX packets:125687 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:739803 (722.4 KiB) TX bytes:6886609 (6.5 MiB)

• Azure Virtual Machines - what fault tolerance do they provide?

  - by Borek

  We are thinking about moving our virtual machines (Hyper-V VHDs) to Windows Azure but I haven't found much about what kind of fault tolerance that infrastructure provides. When I run VHD in Azure, I've got two questions: Is my VHD and all the data in it safe? I think that uploaded VHDs use the "Storage" infrastructure so they should be automatically replicated to multiple disks and geographically distributed but should I still make a full-image backup just to be safe? (Note that of course I will be backing up the actual data inside VMs that I care about; I just want to know if there is a chance greater than 0.0000001% that one day I will receive an email from Microsoft telling me that my VM is gone and that I should create or restore it from scratch). Do I need to worry about other things regarding the availability of my VMs? I mean, when I have an on-premise server I need to worry about the hardware itself, about the host operating system, what would happen if my router failed, if my Hyper-V's C: drive failed etc. Am I right in thinking that with Azure, their infrastructure takes care of all of this? Thanks.

• Window 7 image in vmware will allow network connection out but not http

  - by Ormis

  I am currently trying to create a set of images to deploy on my network, but I've run in to a snag. When I create my own Windows 7 image I can successfully use NAT for connecting to the network but whenever I try to access a webpage I get nothing. To be more specific, All firewalls/iptables are disabled on my host machine, my virtual machine, and my network. I can do lookups and all addresses respond correctly (i'm even using Google's DNS). On the host OS i have full connectivity. On the virtual machine I can ping any device I want and all addresses resolve correctly. Within a browser I cannot reach any page via hostname or IP. I feel almost like port 80 is being blocked but i can't find any reason this would be the case. If anyone has had this occur before, I would love some insight to the problem. I initially asked this on stackoverflow and now my eyes are now opened up to superuser. Thank you for any help you can provide.

• Windows 7 boot animation slows down startup by default?

  - by kngofwrld

  I just upgraded my HDD to an SSD drive. I am running a completely fresh install and enjoy the short boot time. I tweaked the startup to be as fast as I could by removing unneeded apps and such. Nor am I running a solid desktop background (which causes a 30-sec startup delay). I have a 2.1ghz 64 bit laptop with 4 gigs of ram, so it's not a liquid-cooled speed monster, but I checked some super high end PC boot vids on YouTube and noticed that they startup in almost the same time as my machine. I also noticed that the glowing Windows 7 animation plays all the way no matter how fast the PC is. I turned off the animation, and the startup time is unchanged. I turned on verbose startup info and noticed that it runs until the very end, where it looks like it just sits there for no reason waiting for something to happen for a few seconds. So now I think that the Windows 7 startup animation has a timer built into it that forces the computer to wait for no other reason than to play the full animation. Super-fast XP boot vids on YouTube seem to start much faster (and not just because they "have less to load"). Am I imagining things? My question is: How can I turn off not just the animation, but the timer for the animation. Here is a vid that tipped me off, I have no relation to the poster.

• Steps to debugging web site latency and timeout issues

  - by Paperjam

  I have a client who has multiple offices around the country, all of which share the same Internet connection via their WAN. One specific office for this client is experiencing severe latency and timeout issues with my web site. Most, but not all, of the latency occurs on a specific ASPX page where multiple postbacks are made while populating cascading dropdown lists (rapid form submits). The latency is sporadic and can be anywhere from a few seconds to a full timeout. There is no indication that the timeouts are occurring on the server's end. The IT guy for this client is having trouble narrowing down the problem. Since it is affecting only one location for one client, I am led to believe it is not something with my site but something specific to that location. He's measured ping times while using the site and has noticed no real variance in ping times even when the page has timed out. I believe this may be being caused by some sort of Internet filter that doesn't like rapid form submits, but beyond a hunch I haven't a clue. My question is what things should I tell the IT guy to look for? While I'm not trying to provide active tech support for this issue, I would at least like to glean an understanding of what is going on and try to offer some sort of advice. Thank you.
