• How to transition to Comcast with static IP address

  - by steveha

  I have my own email server in my house, on a static IP address. I have had business DSL for over a decade, but I also now have Comcast business Internet. I want to transition from the DSL to the Comcast, and I have some questions. I have a domain name, my own mail server, and a firewall (a PC with two network interfaces, running Devil-Linux). I need to make sure I understand how to set up the Comcast cable box, and how to set up my firewall. First, do I need to change any settings in the cable box? Currently I have only used the cable box by plugging in a laptop, with the laptop doing DHCP. I think I can leave the box alone but I would like to make sure. Second, I'm not sure I understand the instructions Comcast gave me for setting up the firewall. My DSL provider gave me the following information: static IP address, net mask, gateway, and two DNS servers. Comcast gave me: static IP address, routable static IP address, net mask, and two DNS servers, and told me to put the "static IP address" as the "gateway" on the firewall. Is this just Comcast-speak here? Does "routable static IP address" mean the same thing as "static IP address" in my DSL setup, the end-point address that I should publish in the DNS MX records for my email server? Or should I publish the "static IP address", and Comcast will then route all its traffic over the cable box? My plan is: first, I'm going to configure another firewall, so I have one firewall for the DSL and one for the Comcast (rather than madly editing settings to switch back and forth). Then I will publish the new Comcast static IP address as a backup email server address in the DNS MX records, wait a while to let it propagate, and then switch my home over from the DSL to the Comcast. Then I'll change DNS to make that the primary mail address and the DSL the secondary, let that go a while and make sure it seems reliable. Then I'll remove the DSL from the DNS MX records completely, and finally shut down the DSL service. (I thought about keeping the DSL as a backup, but the reason I'm leaving DSL is that it has become unreliable; and I have heard that Comcast business Internet is reliable.) Final question, any advice for me? Anything you think might be useful, helpful, or educational. Thanks.

• What Remote Desktop Solution Do You Use To Service Your Clients' PCs? [closed]

  - by Sootah

  Possible Duplicate: What’s the best Remote Desktop Application? I am the owner of a local computer repair business that primarily services its clients on-site. On the occasions that we do service the machines in the office we generally have one of our techs pick the computer up while they are out and about and bring it back with them. Only rarely will we require the customer to bring us the computer themselves. In order to reduce costs, be much more efficient, and potentially expand our market far beyond what would be feasible with travel required; I am looking at ways that we can service our clients remotely whenever possible. What we're in need of is a solid remote desktop application that will be incredibly easy for our customers to connect to, as well as be robust enough that we don't need the client babysitting the computer during the entire repair. Ideally I would like to use a web-based solution so that we don't have to walk the customers through installing, connecting, and configuring it over the phone. This would be unacceptable because of the level of service they are used to. Effectively we'd want them to be able to just go to a URL, enter a PIN or something, and then they are connected and ready to rumble. (Obviously the option to just email them a link that'd do all this for them would be what we'd be aiming for) Along with the ease of use factor, we would need the product to not require any further intervention on the part of the client after we have connected. Nobody is going to be happy if we have to call them every 15 minutes so they can reconnect to us every time we reboot - so auto-reconnect is an absolute must. The only product I know of right now that does any of this is LogMeIn Rescue. It allows unattended access, the applet is lightweight and installs quickly, and the customer can either enter a PIN on the site or just click a link emailed to them in order to connect. The only real downside I see to LogMeIn Rescue is that it's $120.00/month per technician. While we'd ultimately end up saving far more than that per month just in fuel costs alone, I'd like to explore any other options out there that I may not have come across. Are there any equally good products out there? If so what are they, why do you recommend them, how have you been utilizing them yourself, and what do they cost?

• Bidirectional real-time sync of large file tree between two distant linux servers

  - by dlo

  By large file tree I mean about 200k files, and growing all the time. A relatively small number of files are being changed in any given hour though. By bidirectional I mean that changes may occur on either server and need to be pushed to the other, so rsync doesn't seem appropriate. By distant I mean that the servers are both in data centers, but geographically remote from each other. Currently there are only 2 servers, but that may expand over time. By real-time, it's ok for there to be a little latency between syncing, but running a cron every 1-2 minutes doesn't seem right, since a very small fraction of files may change in any given hour, let alone minute. EDIT: This is running on VPS's so I might be limited on the kinds of kernel-level stuff I can do. Also, the VPS's are not resource-rich, so I'd shy away from solutions that require lots of ram (like Gluster?). What's the best / most "accepted" approach to get this done? This seems like it would be a common need, but I haven't been able to find a generally accepted approach yet, which was surprising. (I'm seeking the safety of the masses. :) I've come across lsyncd to trigger a sync at the filesystem change level. That seems clever though not super common, and I'm a bit confused by the various lsyncd approaches. There's just using lsyncd with rsync, but it seems this could be fragile for bidirectionality since rsync doesn't have a notion of memory (eg- to know whether a deleted file on A should be deleted on B or whether it's a new file on B that should be copied to A). lipsync appears to be just a lsyncd+rsync implementation, right? Then there's using lsyncd with csync2, like this: http://www.axivo.com/community/threads/lightning-fast-synchronization-with-csync2-and-lsyncd.121/ ... I'm leaning towards this approach, but csync2 is a little quirky, though I did do a successful test of it. I'm mostly concerned that I haven't been able to find a lot of community confirmation of this method. People on here seem to like Unison a lot, but it seems that it is no longer under active development and it's not clear that it has an automatic trigger like lsyncd. I've seen Gluster mentioned, but maybe overkill for what I need? UPDATE: fyi- I ended up going with the original solution I mentioned: lsyncd+csync2. It seems to work quite well, and I like the architectural approach of having the servers be very loosely joined, so that each server can operate indefinitely on its own regardless of the link quality between them.

• iptables (NAT/PAT) setup for SSH & Samba

  - by IanVaughan

  I need to access a Linux box via SSH & Samba that is hidden/connected behind another one. Setup :- A switch B C |----| |---| |----| |----| |eth0|----| |----|eth0| | | |----| |---| |eth1|----|eth1| |----| |----| Eg, SSH/Samba from A to C How does one go about this? I was thinking that it cannot be done via IP alone? Or can it? Could B say "hi on eth0, if your looking for 192.168.0.2, its here on eth1"? Is this NAT? This is a large private network, so what about if another PC has that IP?! More likely it would be PAT? A would say "hi 192.168.109.15:1234" B would say "hi on eth0, traffic for port 1234 goes on here eth1" How could that be done? And would the SSH/Samba demons see the correct packet header info and work?? IP info :- A - eth0 - 192.168.109.2 B - eth0 - B1 = 192.168.109.15 B2 = 172.24.40.130 - eth1 - 192.168.0.1 C - eth1 - 192.168.0.2 A, B & C are RHEL (RedHat) But Windows computers can be connected to the switch. I configured the 192.168.0.* IPs, they are changeable. Update after response from Eddie Few problems (and Machines' B IP is different!) From A :- ssh 172.24.40.130 works ok, (can get to B2) but ssh 172.24.40.130 -p 2022 -vv times out with :- OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 172.24.40.130 [172.24.40.130] port 2022. ...wait ages... debug1: connect to address 172.24.40.130 port 2022: Connection timed out ssh: connect to host 172.24.40.130 port 2022: Connection timed out From B2 :- $ service iptables status Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination Chain FORWARD (policy ACCEPT) num target prot opt source destination 1 ACCEPT tcp -- 0.0.0.0/0 192.168.0.2 tcp dpt:22 Chain OUTPUT (policy ACCEPT) num target prot opt source destination Table: nat Chain PREROUTING (policy ACCEPT) num target prot opt source destination 1 DNAT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:2022 to:192.168.0.2:22 Chain POSTROUTING (policy ACCEPT) num target prot opt source destination Chain OUTPUT (policy ACCEPT) num target prot opt source destination And ssh from B2 to C works fine :- $ ssh 192.168.0.2 Route info :- $ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 172.24.40.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth1 default 172.24.40.1 0.0.0.0 UG 0 0 0 eth0 $ ip route 192.168.0.0/24 dev eth1 proto kernel scope link src 192.168.0.1 172.24.40.0/24 dev eth0 proto kernel scope link src 172.24.40.130 169.254.0.0/16 dev eth1 scope link default via 172.24.40.1 dev eth0 So I just dont know why the port forward doesnt work from A to B2?

• GPO Software Uninstall Not Taking Place

  - by burmat

  I am having some trouble with my software GPO's and can't seem to find any answers using Google. I successfully deployed software using my policy but when I delete another, the uninstallation of the software does not take place. What I did: Deployed software using a GPO, used gpupdate /force on the workstation to update, reboot, and install the software Deleted another software installation by: Right-Click All Tasks Remove 'Immediately uninstall the software from users and computers' From there, I did another gpupdate /force to try and get the GPO to refresh and uninstall the software on the workstation. This did not work. I then forced replication between my domain controllers and ran another gpupdate /force on the workstation and this did not uninstall the software. There are not error logs or indications that the uninstall is being triggered when I go into the event viewer, and I know for a fact that the policy is working in other aspects. So my questions is: Where do I look next to find the answer as to why GPO software deployments are working but un-installations are not, based off of what I have already tried? Thank you in advance. UPDATE: After using gpresult /z, there is no indication of a pending un-installation or removal of software. Under the section entitled "Software Installations", the software I am trying to uninstall is not listed. There is no other indication that the software I am trying to uninstall even exists. I also turned on RSoP logging and did (yet another) gpupdate /force to yield no blatant results. There is no indication that an uninstall event was even triggered, let alone incapability or failure. Although I am sure I marked it to uninstall in case of two events (the falling out of the scope of management, as well as the removal of the entry), I am beginning to think the entry just never triggered something that should have been triggered. UPDATE #2: After troubleshooting this (frustrating) application assignment, I have chalked it up as a fluke. I have tested with other software to make sure that the uninstall of other application assignments is actually working, so I am assuming it is something related to the package directly. There is the possibility that my problem resides in something related to what @joeqwerty linked in a comment below but because I can't go back in time, I don't think I will be able to prove it. I will probably be running a script via another GPO to guarantee the un-installation of left over package installs. For now, Evan Anderson is getting the answer because of the debugging information I was able to put to good use. Thank you to everyone that helped contribute so far!

• Where to get laptop replacement parts?

  - by wai

  I am sure some of us have older laptops that still works but just one or two parts started not working very well. However, to send it back to the manufacturer for repair might not be worth the money (as some of them even charge consultation fees just to have it checked) as these old laptops are most probably well beyond warranty. Replacing these one or two parts could give your laptop a new lease of life. For example, I have a Dell Inspiron 640m which the fan recently failed. Everything else still works. I know enough to open up the laptop (after reading the service manual) and put it back together again, hence a replacement fan could save it. However, finding these parts turned out to be difficult. I guess I wouldn't be able to get it from Dell since I have been searching around the Dell forums and concluded if I were going to get Dell to at least talk to me, I would have to pay some money (since my warranty expired). I found this online:- http://www.parts-people.com/index.php?action=item&id=3725 However, as I don't live in the United States, shipping alone would cost me 3 times more than the part in question. In addition, if there's a problem, it would be difficult because I probably would have to mail the parts back (costing more money). One of my friend spilled water on her Macbook, she sent it back to Apple and they told her the cost of repairing it exceeds that of buying a new Macbook. They probably have to change everything except the LCD screen. I opened it up and found that most of the parts are still working, only the RAM had fried. Replaced it and it's working again. For some time before discovering only the RAM fried, I was toying with the idea of replacing the logic board myself but looks like I didn't have to. =) Now I know there's a site for Macbooks used replacement parts:- http://www.ifixit.com/ The question is, does anyone know where to get replacement parts at their own locality? It might benefit the community as a whole. Someone might know a local computer store that sells precisely just the things we needed (for now, I hope to find a shop that sells just the fan). If you own a laptop which you had an easy experience finding the replacement parts, do post that as well. PS: I wish laptop manufacturers have outlets where they sell these replacement parts (or at least let you place an order).

• networking tunnel adapter connections?

  - by Karthik Balaguru

  I understand that Tunnel Adapter LAN is for encapsulating IPv6 packets with an IPv4 header so that they can be sent across an IPv4 network. Few queries popped up in my mind based on this :- If i do 'ipconfig', Apart from ethernet adapter LAN details, I get a series of statments as below - Tunnel adapter Local Area Connection* 6 Tunnel adapter Local Area Connection* 7 Tunnel adapter Local Area Connection* 12 Tunnel adapter Local Area Connection* 13 Tunnel adapter Local Area Connection* 14 Tunnel adapter Local Area Connection* 15 Tunnel adapter Local Area Connection* 16 Except for the *16, all the other Tunnel Adapter Local Area Connections show Media Disconnected. Why is the numbering for the Tunnel adapter LAN not sequential? It is like 6, 7, 12, 13, 14, 15, 16. A strange numbering scheme! I tried to figure it out by thinking of some arithmetic series. But, it does not seem to fit in. There is a huge gap between 7 and 12. Any ideas? What is the need for so many Tunnel Adapter LAN connections? Can you tell me a scenario that requires all of those ? I did ipconfig /all to get more information. From the listing, I understand that: 16, 15, 14, 12 are Microsoft 6to4 Adapters 13, 6 are isatap Adapters 7 is Teredo Tunneling Pseudo-interface I understand that the above are for automatic tunneling so that the tunnel endpoints are determined automatically by the routing infrastructure. 6to4 is recommended by RFC3056 for automatic tunneling that uses protocol 41 for encapsulation. It is typically used when an end-user wants to connect to the IPv6 Internet using their existing IPv4 connection. Teredo is an automatic tunneling technique that uses UDP encapsulation across multiple NATs. That is, It is to grant IPv6 connectivity to nodes that are located behind IPv6-unaware NAT devices ISATAP treats the IPv4 network as a virtual IPv6 local link, with mappings from each IPv4 address to a link-local IPv6 address. That is to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network. That is, to put in simple words, ISATAP is an intra-site mechanism, while the 6to4 and Teredo are for inter-site tunnelling mechanisms. It seems that Teredo should alone enabled by default in Vista, But my system does not show it to be enabled by default. Interestingly, it shows a 6to4 tunnel adapter (Tunnel adapter LAN connection 16) to be enabled by default? Any specific reasons for it? If i do ipconfig /all, why is only one Teredo present while four 6to4 are present ? I searched the internet for answers to the above queries, but I am unable to find clear answers.

• How can Windows XP/7 users cleanly connect to Mac OS X Server 10.9.4 Mavericks with Active Directory integration?

  - by JakeGould

  I’m a Linux/Unix systems admin who also manages a Macintosh server infrastructure & there is a lone Mac Mini in the mix running 10.9.4 that I would like Windows XP & Windows 7 users to connect to with little or no hassle. The problem? Windows users can’t seem to even get to the point of a password prompt yet connect. Mind you this server replaced a Mac OS X 10.6.8 server that had issues, but never had issues with Windows users connected. The gist of this post is: The tons of different messages out there about Mac OS X 10.9.4 Samba support are mind-numbingly confusing. Can anyone share some solid specifics here? I’ve read pieces like this one here that suggest turning off file sharing & then adding a share with AFP/SMB enabled would work. But the suggestion seems to apply to 10.8. And from what I know a lot has changed in Samba support in 10.9 let alone the iterations to 10.9.4. Then I found this great tutorial here that explains things step-by-step. Which seems like it should work, but the problem is the example given applies to a local user created on the Mac when I would like users in an Active Directory group—which the Mac is bound to—access the Mac Mini shares. There are also tons of great tips here on MacWindows.com but nothing seems solid to the issue I am facing. So from what I am reading these are my options: Local User Versus Active Directory: Setup a common local user on the Mac OS X 10.9.4 server to be used for Samba sharing since Active Directory won’t work. Is this really the case? Because loss of AD integration is a major pain. Do Extended File Attributes Get Retained from Windows Users: If this were to work, how do extended attributes come into play? Loss of metadata & related info is not an option. How Fragile is Any of this to Updates: How does any of this shake out with Mac OS X updates as well as Windows updates? Installing Official, Open Source Samba: Would upgrading the Samba install on the server to the official open source Samba via a package like SMBUp or via the Hombrew method described here help or make the issue worse? I fully understand there have historically been issues in mixed environments, but nowadays Windows users connecting to a Mac seem to have a truly hellish road ahead of them. Unless I am missing something?

• Is Steam for Mac effectively running as superuser?

  - by godDLL

  When you download the client it does not weigh too much, and seems to do very little. Inside the app bundle there is a script that—upon inspecting the environment and deciding you're not running Linux—launches the client, which downloads the full support environment and resources. For this to happen (all of this is saved inside the bundle, the app bundle gets updated in this process) Steam wants Universal Access for Assistive Devices, and your password. Cacheable resources, preferences (like keyboard shortcuts), support files (like game hardware requirement lookup tables) live inside the bundle, not in ~/Library/{Application Support|Preferences|Cache}; games' data get dumped into ~/Documents/Steam Content. I'd describe myself as a bit OCD (which really says a lot), and I wouldn't care that much still. I'd go comb this hairy mess and find out where stuff is, when and if I need to, even if it's in an unfamiliar place; that does not actually tick me off. Well, a little bit. What makes me concerned is the way Steam needs both Access for Assistive Devices, and my password to run. The former gives it the ability to talk very intimately with running apps and the underlying system; while the latter (admin account) could very well give it and it's publishers unrestricted access to all my software, hardware and data. With publishers like Rockstar using scene NOCD cracks to publish their games on Steam, I'm not so sure I'm OK with this. I'd like more games made available for the MacOS X and all the pretty machines that run it, but this arrangement does not seem very Mac-like to me. It looks like Valve is going around system security measures and best practices, foregoing sandboxing, code signing, relatively sane structured organization; all the things that would appeal to someone who's no fun at parties at all, and will die alone, in his long dead mother's basement… wait. Right. Anyway. Can we get some input on Steam for Mac security at the end-user machine, from someone who understands how Accessibility API works, whether games distributed on Steam can read and write outside the user homefolder, collect data from other running apps, or similar?

• How can I verify that my SSD is performing as it should?

  - by Jon Skeet

  EDIT: Okay, so I've no idea what caused the change, but after trying loads of different things to work out what was wrong, I've rerun the WEI (about the 4th time in total) and the score has jumped to a far more respectable 7.3. I'm going to leave well alone now :) I've got a brand new 256GB SSD (Crucial CT256M225) which should have stellar performance. However, on my (also brand new) Dell Studio 1557 with Windows 7 Professional 64 bit, it's only giving a performance index of 5.9. I realise the performance index should be taken with a bit of a pinch of salt, but I wonder whether something's wrong. Given this paragraph from this MSDN article on Windows 7, I'd expect to see a high 6.X or possible a 7.X figure: In Windows 7, there are new random read, random write and flush assessments. Better SSDs can score above 6.5 all the way to 7.9. To be included in that range, an SSD has to have outstanding random read rates and be resilient to flush and random write workloads. In the Beta timeframe of Windows 7, there was a capping of scores at 1.9, 2.9 or the like if a disk (SSD or HDD) didn’t perform adequately when confronted with our random write and flush assessments. Feedback on this was pretty consistent, with most feeling the level of capping to be excessive. As a result, we now simply restrict SSDs with performance issues from joining the newly added 6.0+ and 7.0+ ranges. SSDs that are not solid performers across all assessments effectively get scored in a manner similar to what they would have been in Windows Vista, gaining no Win7 boost for great random read performance. How can I diagnose any performance issues with either the disk or how Windows 7 is handling it? Are there any particularly good tools you'd recommend? One note of curiosity: I couldn't install the firmware update (to 1916) until I changed my BIOS handling of the drive to ATA mode; after installing the firmware I tried to boot the Windows installation DVD - but that only worked after turning it back to AHCI mode (which I've left it in). Installing Windows 7 took longer than I expected - it sat at the "Windows is loading files" prompt for a very long time. Likewise it was on "Expanding files (0%)" for a long time. Since installation it's been fine though - but I don't know whether it's really providing quite as beefy performance as it should. EDIT: My netbook with the 64GB equivalent drive has a performance index of 6.6...

• Avoid read-write access to bad sectors on HDD to continue working on the HDD

  - by goldenmean

  I have a HP Pavilion dv6446 notebook. It had Windows Vista Home premium. After 4.5+ years of usage, just recently it started malfunctioning. While working fine, its screen goes white or sometimes some thin black lines horizontally. Laptop freezes. Hard reboot works. Again it works for some 2 hrs or so, same error. To diagnose I did run the Memory and Hard disk check which is present in the Bios Setup. Memory test passed. Hard disk test returned an error saying something like - "Replace the hard disk". Bad.. Some sectors or platters have gone bad on the disk. (I confirmed this later by further tests mentioned below) Then I tried installing a Ubuntu 11.10. It listed 3 partitions /dev/sda1, sda2, sda2. It again gave error and could not install grub loader on /dev/sda1. Bad sectors. Then redid the Ubuntu installation, this time asked to to install the Ubuntu on /dev/sda3. and kept /dev/sda1 for /home. Installed fine, and works fine as well. Due to unavailability of WiFi/ Ethernet driver for that adapters under Ubuntu( at least I could not configure them and get the networking working at all), I decided to go back to reinstall windows Vista. It did install fine. I did not have to format one data partition which has my data. I just formatted one partition which installed Windows So in effect HDD has not undergone a full format here. Worked ok for 1 day. But same white screen and freeze happened. Looks like while it is in use, it accesses the bad sectors for storing some data and that's when it bombs. I am inclined to think HDD has not failed fully or crashed but has developed bad sectors. Else if it was a HDD crash, it would have refused to boot at all let alone install on it. Questions: Is there any HDD test check under windows or any such tools windows/linux based ewhere which can identify the bad sectors of the HDD and 'lock/isolate' them from further read-write access of any kind. If not what are my options, if any to salvage this laptop HDD without replacing it. EDIT: Would the Disk Error checking tool under windows help in any way?

• apcupsd on Linux does not report on APC BackUPS Pro 900

  - by lserni

  From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64).

If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

• Win7 x64 unresponsive for a minute or so. HD failing?

  - by Gaia

  On a fully updated Win7 x64, every so often the system stalls for a minute or so. This has been going on for a couple months now. By stalling I mean the mouse responds and I can move windows around, but any window, any program, that is open becomes whiteish when I select it AND any new programs will not open. It doesn't matter what kind of program it is. When the stall stops all clicks I made (open new programs for example) take effect. Nothing shows up consistently (as in every time this happens) in the event log. Today though I was able to find something, but it doesn't reveal much other than the "system was unresponsive". It's a 7009 for "A timeout was reached (30000 milliseconds) while waiting for the Windows Error Reporting Service service to connect." It doesn't matter if I have any USB devices plug-in or not. I've ran Microsoft Security Essentials and Malwarebytes. While the machine is unresponsive, I've noticed that Drive D (the other partition on the single internal HD in this laptop) is displayed like this in explorer. This never occurs with Drive C or any other drive on the machine. . SMART report for the physical drive: Read benchmark by HD Tune 5 Pro, probably the most telling piece of the puzzle. Isn't this alone enough to see there is a problem with the drive, regardless of whether the unresponsiveness is caused by such purported problem? Here is a short hardware report: Computer: LENOVO ThinkPad T520 CPU: Intel Core i5-2520M (Sandy Bridge-MB SV, J1) 2500 MHz (25.00x100.0) @ 797 MHz (8.00x99.7) Motherboard: LENOVO 423946U Chipset: Intel QM67 (Cougar Point) [B3] Memory: 8192 MBytes @ 664 MHz, 9.0-9-9-24 - 4096 MB PC10600 DDR3 SDRAM - Samsung M471B5273CH0-CH9 - 4096 MB PC10600 DDR3 SDRAM - Patriot Memory (PDP Systems) PSD34G13332S Graphics: Intel Sandy Bridge-MB GT2+ - Integrated Graphics Controller [D2/J1/Q0] [Lenovo] Intel HD Graphics 3000 (Sandy Bridge GT2+), 3937912 KB Drive: ST320LT007, 312.6 GB, Serial ATA 3Gb/s Sound: Intel Cougar Point PCH - High Definition Audio Controller [B2] Network: Intel 82579LM (Lewisville) Gigabit Ethernet Controller Network: Intel Centrino Advanced-N 6205 AGN 2x2 HMC OS: Microsoft Windows 7 Professional (x64) Build 7601 The drive less than 1 year old. Do I have a defective drive? Seagate Tools diag says there is nothing wrong with the drive... UPDATE: I noticed that the windows error reporting service entered the running state then the stopped state and the space between the two events was exactly 2 minutes. Which error it was trying to report I don't know. I check the "Reliability Monitor" and it shows no errors to be reported. I've disabled the windows error reporting service to see if the problem stops.

• UAE and the mysteries of unreachable websites

  - by 0plus1

  I write here because I'm really lost, please stay with me because it's not easy to explain. A company asked me to set-up a private server, now I'm a programmer so I got a solution with technical support and cpanel which helped me to setup everything and it's working smoothless. I'm by no means a professional sysadmin, but I have a fair knowledge of server configurations, but this problem is way over my knowledge, and apparently way over the knowledge of most sysadmins, I really hope that here I'll find someone with enough experience to help me or at least give me more insight. Now this company for which I'm consulting operates in the UAE (United Arab Emirates) and from there the server is almost unreachable. It started with ns not registering in the UAE, after a week that sorted itself out and now the site is indeed reachable, but it takes almost 2 minutes to load a webpage with one line of text. Emails go in timeout. The domain currently parked there has been bought appositely for tests, the main one that was supposed to go there, after a catastrophic week has been transferred to a shared hosting solution in the UK, and from there it works like a charme. Now after doing some research I discovered that I'm not alone in this, there are several reports of webmasters discovering that their website is not reachable inside the UAE, and mind this has nothing to do with the state-wide block of questionable sites, because in that case an error message appears, this seems to be related to the infrastructure of the UAE, which apparently reroutes everything through their own "fake" internet. Apparently new servers with their own IP are not recognized (yet?) by the UAE infrastructure, while shared hosting solutions seeing that they operates tons of other websites are more likely to be part of the UAE network. Now my questions are: 1) Has someone a real explanation for this? The only thing I can think of is that the server is on a new IP that is not yet recognized by the UAE, but that doesn't explain why it loads (even if after 2 minutes). I don't have any help from within the UAE as the only people that are "experts" are questionable companies that simply try to sell their own services. 2) If there is really some kind of block of new servers, is it possible to know before if a server is reachable from within the UAE, currently this is not a ns problem as even accessing the server with its IP result in a 2 minute wait. 3) Can it be that the problem lies somewhere else? There are some tests that I can perform? I'm not physically in the UAE, but I can ask the people there, or use teamviewer. Could it be some misconfiguration on the server (mind that the site works EVERYWHERE else in the world). Thank you for ANY kind of help

• What is it that kills laptop batteries?

  - by Mala

  There are many superstitions on what you must never do lest your battery become worthless - and by worthless I mean hold about 16 - 24 seconds of charge. This has happened to every laptop I have ever owned, and I just got a new one, so please help me sort out fact from fiction. Here are some of the things I've heard: Do not keep your laptop fully charged. You must run it completely down every so often. Do not use your laptop plugged in to the wall. Only plug it in when it needs charge. If you will not be using your laptop for a long period of time, don't leave it at full charge. Do not leave your laptop running 24/7. The first two I know to be complete fiction: this was true of old batteries such as you might have had in an iPod in 2003, but modern batteries function better when kept at or near full charge. Devices even have circuitry to prevent you from completely depleting your battery, as this is dangerous. The third point sounds probable, and I'd be interested to know if it was true. However, it doesn't really apply to me because I'm not really the type to leave my laptop alone for a day, much less a "long period of time" The fourth seems most likely of the above, but only because of causality: I have always done this, and my batteries have always crapped out on me. I've generally treated a laptop like a desktop with a battery backup, and that I can move from one room to another if necessary. The fact that my batteries tend to last less than 30 seconds has further entrenched this behavior. Should I be trying to break this habit? Are there any other things that ruin laptop batteries? I love that I can actually use my new laptop unplugged :) I'd like to keep it that way. Update: Additional question: If the computer will be used for an extended period of time plugged in, does it make sense to remove the battery first? Update 2: I know people with laptops older than mine, who actively use their laptops as much as I do, and their batteries still hold about an hours' charge while mine holds less than 30 seconds, hence my belief that something I'm doing kills them.

• Windows 7 Administrator HomeUsers Account

  - by Charles Carrington

  I'm trying to login to my Windows 7 PC from another PC so that I can transfer files to the Windows 7 PC. I've just installed Visual Studio 2008 on my new PC, and I wan't to transfer all of my work from my old machine to my new one. When I first set up a user on the Windows 7 PC after a reformat, the account created had a Group field that read "HomeUsers; Administrators" when viewing it from the User Accounts screen. You get to this screen by typing "netplwiz" in the search field of the Start Menu. I changed the Group of this account to Administrators before I realized that it was assigned to two Groups -- "HomeUsers; Administrators" as I mentioned above. I was trying to make sure that it was an Administrator account so I didn't have to type in a password everytime I wanted to install software. I can use this computer normally without being asked for an administrator password all the time when I want to install new software, but I can't log in to this PC from another PC because I don't have an account that has a Group of "HomeUsers". I should have left the account alone; everything would've been fine. But there doesn't seem to be a way to assign it to two groups after the initial assignment that take place automatically when you are setting up your computer for the first time. If you assign "HomeUsers" to the account, the Group field on the User Accounts screen will just read "HomeUsers". If you assign "Administrators" to the account, the Group field on the User Accounts screen will just read "Administrators". There's no way to make it read "HomeUsers; Administrators" again. If you don't have at least one account that is a "HomeUsers" account, you cannot log in to the PC from another PC on the network. If you don't have an account that is an "Administrators" account, you cannot install software on your machine without being asked for an Administrator password all the time, which is very annoying. I want an account on my Windows 7 PC that I can use to install software without being asked for a password AND that I can log into from another PC on the network to transfer files. If I could make the Group field read "HomeUsers; Administrators" of my primary account on the Windows 7 PC when I go to the User Accounts screen by typing "netplwiz" in the search field of the Start Menu, my primary account would do what I want it to do. Does anybody know how to make an account in Windows 7 a "HomeUsers" account AND an "Administrators" account? As I said before, Windows 7 does this for you automatically when you first set up your computer. But if you change it inadvertently, there is no way to change it back. At least I don't know how to do it. If anybody has any ideas on how to fix this, I would greatly appreciate it. Thanks, Charles Carrington

• Unable to load type error in ASP.NET 4 application on Windows Server 2003 / IIS6 -- only happens after first worker process recycle

  - by Daniel Coffman

  I'm running an ASP.NET 4.0 web application on IIS6 (Windows Server 2003 x64). This app is one of many running on this server under the Default Web Site -- but is alone on it's own application pool because the other sites are all running ASP.NET 2.0 still. When I deploy my application, it works just fine until the application pool recycles or kills its worker process (by default 2 hours or 20 minutes with no activity). After this, I get the error: "Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information." Refreshing the page, recycling the application pool, and iisreset do nothing. But, I can bring the site back online again for a little while by simply redeploying it. The stack trace seems to start at an EntityDataSource -- see below: [ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.] System.Reflection.RuntimeModule.GetTypes(RuntimeModule module) +0 System.Reflection.Assembly.GetTypes() +144 System.Data.Metadata.Edm.ObjectItemConventionAssemblyLoader.LoadTypesFromAssembly() +45 System.Data.Metadata.Edm.ObjectItemAssemblyLoader.Load() +34 System.Data.Metadata.Edm.AssemblyCache.LoadAssembly(Assembly assembly, Boolean loadReferencedAssemblies, ObjectItemLoadingSessionData loadingData) +130 System.Data.Metadata.Edm.AssemblyCache.LoadAssembly(Assembly assembly, Boolean loadReferencedAssemblies, KnownAssembliesSet knownAssemblies, EdmItemCollection edmItemCollection, Action`1 logLoadMessage, Object& loaderCookie, Dictionary`2& typesInLoading, List`1& errors) +248 System.Data.Metadata.Edm.ObjectItemCollection.LoadAssemblyFromCache(ObjectItemCollection objectItemCollection, Assembly assembly, Boolean loadReferencedAssemblies, EdmItemCollection edmItemCollection, Action`1 logLoadMessage) +580 System.Data.Metadata.Edm.ObjectItemCollection.ExplicitLoadFromAssembly(Assembly assembly, EdmItemCollection edmItemCollection, Action`1 logLoadMessage) +193 System.Data.Metadata.Edm.MetadataWorkspace.ExplicitLoadFromAssembly(Assembly assembly, ObjectItemCollection collection, Action`1 logLoadMessage) +140 System.Web.UI.WebControls.EntityDataSourceView.ConstructContext() +756 System.Web.UI.WebControls.EntityDataSourceView.ExecuteSelect(DataSourceSelectArguments arguments) +147 This is a bug filed for the same (or similar) problem: http://connect.microsoft.com/VisualStudio/feedback/details/541962/unable-to-load-one-or-more-of-the-requested-types-connected-with-entitydatasource Question: Has anyone seen this and have advice?

• What the best way to recover from when your RAID H/W incorrectly thinks a disk is missing

  - by Software Monkey

  I have a Windows 7 system with an MSI motherboard (running the latest AMD BIOS) and two of my four disks (not the system boot disk) configured via the Mobo as RAID-1. After a normal system restart today, the RAID BIOS reports that one of the two drives has been disconnected or has failed. It's not really failed; via recovery tools I can verify that if I take the BIOS out of RAID mode. But I can find no way to re-add the second hard disk to the array and rebuild via the BIOS - the only option seems be to delete the array and recreate it, but I've done that once before and it blows away the disk. It's done this once before, however on a subsequent reboot after double-checking the drive cabling (but not changing anything) and it boot up fine. So I think the mobo RAID is a little bit flaky. At this point I would like to remove the RAID drivers, change to AHCI mode and switch over to using a Windows 7 dynamic mirror disk. But the RAID drivers seem somehow deeply bound into the Windows startup - I can't find anything like the good ol' safe-mode in Windows 7. If I boot from the Win 7 install disk in ACHI mode I can use recovery tools to log in to the Windows 7 installation, so the boot drive it seems fine with ACHI mode. Additionally, I can see all my other disks, run chkdsk on them and they seem to be fine. If I try to boot from the HDD in AHCI mode, it just reboots part way through, presumably because the RAID drivers load and conflict with the BIOS being set to AHCI. So: How do I strip the RAID drivers from my Win 7 installation? If I delete the RAID logical disk, will it really delete partitioning information, or is that just a poorly worded message when it says the data on the disk will be deleted? If I disconnect the 2 disks in a RAID array, then delete the logical disk array, and then reconnect and reboot still in RAID mode, will the disks simply revert to RAID single-disks like my other 2 and then maybe I can leave windows with RAID drivers by operate the disks as singles with 2 of them in a Windows dynamic disk mirrored setup? Does Windows 7 have anything like the Windows XP Repair Install, where it will reinstall the O/S binaries from CD, but leave apps and setup alone. I am really hoping I don't have to do a complete reinstall of Windows 7 - the last one, when I upgraded from XP, took me two days to get everything set up and installed.

• Diff 2 files while ignoring parts of lines

  - by Millianz

  I would like to diff a file system. Currently my bash script prints out the file system recursively into a file (ls -l -R) and diffs it with an expected output. An example for a line in this file would be: drw---- 100000f3 00000400 0 ./foo/ My current diff command is diff "$TEMP_LOG" "$DIFF_FILE_OUT" --strip-trailing-cr --changed-group-format='%' --unchanged-group-format='' "$SubLog" As you can see I ignore additional lines in the current output file, I only care about lines that match with the master output. I now have the problem though that some files may differ in size, or a folder might even have a different name, but due to it's location I know what access rights it should have. For example: Output: ------- 00000000 00000000 528 ./foo/bar.txt Master: ------- 00000000 00000000 200 ./foo/bar.txt Only the size differs here, and it doesn't matter, I would like to just ignore certain parts of the diff, kind of like an ansi c comment. Master: ------- 00000000 00000000 /*200*/ ./foo/bar.txt -- OR -- Master: d------ 00000000 00000000 /*10*/ ./foo//*123123*///*76456546*//bar.txt Output: d------ 00000000 00000000 0 ./foo/asd/sdf/bar.txt And still have it diff correctly. Is this even possible with diff, or will I have to write a custom script for it? Since I'm fairly new to cygwin I might be using the completely wrong tool all together, I'm happy for any suggestions. Update: Taking a step back, here is the general task at hand that I want to achieve. I want to write a script that checks the file system to see if the read/write permissions are set up correctly. The structure of the file system is under my control, so I don't have to worry about it changing too much. Sometimes folders/files might not be present, but if they are their permissions must be checked. For Example assume that the following is a snapshot of the current file system structure drw ./foo drw ./foo/bar -rw ./foow/bar/bar.txt drw ./foo/baz -rw ./foo/baz/baz.txt And this is what the file system structure might dictate, i.e. if these folders / files are present, the permissions must match. drw ./foo drw ./foo/bar -rw ./foo/bar/bar.txt --- ./foo/bar/foobar.txt drw ./foo/baz -rw ./foo/baz/foobaz.txt In this case the file system checked out ok, since all files present match their expected values. The situation becomes more complicated as soon as certain folders might have any arbitrary name, only due to their location I know what their permissions should be. Assume that the directory ./foo/bar in the above example might be such a case, i.e. instead of bar the folder could have any name, but still match the -rw permissions. This seems like a very complicated situation, and I'm not even sure if I can solve it with bash scripting alone. I might have to write an actual application.

• PHP-FPM performing worse than mod_php

  - by lordstyx

  Recently the website I maintain has been growing a lot and I saw the point coming where I'd want to switch from apache to nginx, because I kept on reading that it performs way better. Now I've done the switch, and I have to say, nginx is keeping up just fine. However, php-fpm is forming a problem. Where the php pages used to take 0.1 second to generate with the same load they now take around 3 seconds! Furthermore the error.log from nginx is being spammed with errors like: upstream timed out (110: Connection timed out) while connecting to upstream, client: ... I also tried using unix sockets instead, but those would complain about the following: connect() to unix:/tmp/php5-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream I've fiddled with settings here and there but nothing seems to work. Changing the amount of pm.max_children doesn't seem to help a lot either, but with it's current amount at 350 it seems to be the lesser of all evil. The server that's being used has 3 GB RAM (not all of it is free due to a MySQL server also running) along with 2 dual-core processors (4 cores in total). Am I doing something majorly wrong with the settings here, or is the server simply not capable enough?

• Troubleshooting Network Speeds -- The Age Old Inquiry

  - by John K

  I'm looking for help with what I'm sure is an age old question. I've found myself in a situation of yearning to understand network throughput more clearly, but I can't seem to find information that makes it "click" We have a few servers distributed geographically, running various versions of Windows. Assuming we always use one host (a desktop) as the source, when copying data from that host to other servers across the country, we see a high variance in speed. In some cases, we can copy data at 12MB/s consistently, in others, we're seeing 0.8 MB/s. It should be noted, after testing 8 destinations, we always seem to be at either 0.6-0.8MB/s or 11-12 MB/s. In the building we're primarily concerned with, we have an OC-3 connection to our ISP. I know there are a lot of variables at play, but I guess I was hoping the experts here could help answer a few basic questions to help bolster my understanding. 1.) For older machines, running Windows XP, server 2003, etc, with a 100Mbps Ethernet card and 72 ms typical latency, does 0.8 MB/s sound at all reasonable? Or do you think that slow enough to indicate a problem? 2.) The classic "mathematical fastest speed" of "throughput = TCP window / latency," is, in our case, calculated to 0.8 MB/s (64Kb / 72 ms). My understanding is that is an upper bounds; that you would never expect to reach (due to overhead) let alone surpass that speed. In some cases though, we're seeing speeds of 12.3 MB/s. There are Steelhead accelerators scattered around the network, could those account for such a higher transfer rate? 3.) It's been suggested that the use SMB vs. SMB2 could explain the differences in speed. Indeed, as expected, packet captures show both being used depending on the OS versions in play, as we would expect. I understand what determines SMB2 being used or not, but I'm curious to know what kind of performance gain you can expect with SMB2. My problem simply seems to be a lack of experience, and more importantly, perspective, in terms of what are and are not reasonable network speeds. Could anyone help impart come context/perspective?
