• Can I clone my hard drive to an external and boot from the clone?

  - by willbuntu

  First thing: I am not asking what software I'm supposed to use. I already know the answer: Ghost (proprietary), Clonezilla, and dd (if I'm careful). What I really want to know is if it is possible to (essentially) bit-for-bit clone my entire installation (OS, installed software, activation(s), etc.) to an external USB hard-drive, and then boot off of that (if I need to, I know how to edit BIOS settings and use Plop boot manager), and work with it day-to-day as if there was virtually no difference from using my internal HDD now. Again, I'm not asking how to install Windows to an external (because I know I'd need to do some special workaround), I'm asking if I can clone everything and boot off of it. In case you're wondering why I'm going to this trouble: I'm using a Lenovo Essentials laptop that has an unmodifiable partition table (due to recovery crap), and has all 4 of its partitions spoken for (3 primary, one extended, cannot change the extended). Anyway, my thought is that if I can clone everything and boot off of it when I need to, and just have a Linux distro on the internal HDD, then that could work.

• How can I rapidly switch hosts?

  - by EAMann

  I'm in the process of migrating a forum setup from one version of the software on one machine (older shared Windows host) to a new VPS (Windows Server 2008). To install the software, I used my hosts file to temporarily point the domain at the new IP address. To see the old site, I obviously re-edit the hosts file to remove the reference. But this leaves me constantly adding/removing a # from my hosts file just so I can switch back and forth between the two servers. Is there a way to do this more rapidly? I've found a handful of toggling batch scripts, but all they do is automate the addition/removal of the # character ... so there's still a noticeable lag where I have to repeatedly hit F5 to force my system to detect the new settings. Ideally, I could view both servers at the same time on the same machine. Maybe one through a regular browser session and one through some kind of a proxy. Unfortunately, I don't have the first idea how to set that up. Ideas?

• Scripting around the lack of user:password@domain url functionality in jscript/IE

  - by Idiomatic

  I currently have a jscript that runs a php script on a server for me, dead simple. But... I want to be atleast somewhat secure so I setup a login. Now if I use the regular user:password@domain system it won't work (IE decided it was a security issue). And if I let IE just remember the password then it pops up a security message confirming my login every time (which kills the point of the button). So I need a way to make the security message go away. I could lower security settings, which tbh I am fine with but nothing seems to make it fuck off (there might be some registry setting to change). Find a fix for jscript that will let me use a password in the url. There used to be a regedit that worked for older systems which allowed IE to use url passwords (not working on my 64bit windows7 setup) though I doubt that'd have helped jscript anyways (since it outright crashes). Use an app other than IE. Inwhich case I'm not sure how to go about it, I want it to be responsive and invisible so IE was a good choice. It is near instant. Use XMLHttpRequest instead of IE directly? May even be faster but I've no idea if it'd help or just have the same error. Use a completely different approach. Maybe some app that can script website browsing. var args = {}; var objIEA = new ActiveXObject("InternetExplorer.Application"); if( WScript.Arguments.Item(0) == "pause" ){ objIEA.navigate("http://domain/index.html?pause"); } if( WScript.Arguments.Item(0) == "next" ){ objIEA.navigate("http://domain/index.html?next"); } objIEA.visible = false; while(objIEA.readyState != 4) {} objIEA.quit();

• What's Keeping My Computer Awake?

  - by phantomdata

  First the question; How do I figure out what is preventing my Windows 7 computer from going into sleep mode? Second; some background... I've been struggling with this for a few days and am utterly perplexed. I setup sleep mode on my Windows 7 PC a few weeks ago, and all was well. The PC would sleep as expected and I was snuggly in knowing that my computer was saving power and some wear and tear on the components (we'll leave the 'is it better to sleep' debate for another thread/day, please don't start it). Well, I noticed the other night that my system stopped ever going to sleep. I set the sleep time down to 1 minute and wandered fully away from the PC (ensuring that no errant mouse or keyboard movements would occur) and the PC never went to sleep. I've also observed this over longer intervals as well, such as overnight. I have sleep mode enabled, of course "multimedia settings - When Sharing Media" is set to allow the computer to sleep. "powercfg -lastwake" show nothing of interest, since it never goes to sleep and can't wake up. "powercfg /requests" shows 3 entries - all "[DRIVER] ?". I assume that 2 of these are my mouse and keyboard - as I've recently used them to run the powercfg command. I'm at a loss for the third though. I've unhooked all USB peripherals save for my keyboard and mouse. Wake on LAN is disabled in my BIOS. I know that you can disable all apps from waking/preventing sleep - but I want the ability to remain for those apps that do legitimately need to keep the system awake. So; does anyone know of a way to figure out what the 3rd phantom "[DRIVER] ?" is in powercfg /requests?

• Netbook thinks it is a desktop

  - by Narcolapser

  Question: Are, and if so what, there packages for download that I can get netbook to understand it is not a desktop and that it is a netbook. Info: I'm running an Acer Aspire One with ubuntu desktop 9.10. I tried Ubuntu Netbook Remix first but it has graphics issues with the aspire one. So I changed to Ubuntu Desktop. It was the only distro (after debian, centOS, Fedora, and Knoppix all failed me) that I managed to get working. The only thing is that it is having issues doing things that a netbook/laptop should be doing. most notably is that it will run it's battery dead if I close the screen and throw it into my back pack. It seems to just stay fully on and runs it's self to death. also it will lock up some times if I close the screen and come back to it 10 or 20 minutes later. It also won't retain volume settings when I reboot, as well as screen brightness. and just a couple of other things that I can't quite put my finger on, but just seem amiss. like I said, Essentially my netbook thinks it is a desktop, how can I fix this? ~N

• Outlook 2010 - Missing New Mail Envelope Icon

  - by sdoca

  I've seen a number of posts related to this issue, but none with a solution that works for me. I have: Windows 7 Professional 64 bit Office/Outlook 2010 "Show an envelope icon in the taskbar" checked "Hide When Minmized" selected "Show icon and notifications" selected for Outlook in my taskbar settings This used to show me the envelope icon in my notifications area. Then something happened with my user profile and the sys admins created me a new one. Since then, the envelope only displays if Outlook is not minimized. It doesn't matter if I unselect "Hide When Minmized", the icon still doesn't display when new mail arrives. If I select "Display a Desktop Alert", then the icon is displayed. However, I HATE the desktop alert as I find it too intrusive/distracting. Is there some way to just get the envelope icon working (again)? UPDATE More testing and sometimes I will and sometimes I won't get an envelope icon with the desktop alert turned on. This is driving me nuts!! UPDATE TWO I like my notification area of the taskbar to be clean. So, all icons are set to "Only show notifications" except for Outlook as noted above. I've noticed the envelope icon is being displayed in the expanded notification area when I click on the up arrow to view all icons. So, it is being added to the notification area, but not displayed. It's a rather useless feature now...

• Must have local user to authenticate Samba to AD?

  - by Phil

  I've got a CentOS 5.3 server with Samba running. I've joined this server to my domain in the hopes of allowing AD users some access to my Samba shares. I've found that this works, but only as long as the AD username that I'm trying to authenticate with is also a local user on the server. In other words, if I'm trying to access a share, and try to authenticate with the AD username "joe", I get errors unless I create a user named 'joe' on the server. I don't have to create a matching password or anything....the local user's password is always blank, so I do know that the authentication is actually happening against the AD. Here's my smb.conf file: [global] workgroup = <mydomain> server string = <snip> netbios name = HOME security = ADS realm = <mydomain.com> password server = <snip> auth methods = winbind log level = 1 log file = /var/log/samba/%m.log [amore] path = /var/www/amore browseable = yes writable = yes valid users = DOMAIN\user1 DOMAIN\user2 DOMAIN\user3 DOMAIN\user4 I would assume that my kerberos settings are fine, as I've joined the domain and can use wbinfo to see users and groups. However, I can provide that info if necessary. Anyone have any ideas?

• How do I connect remotely to SQL Server from Windows client?

  - by humble_coder

  Hi All, Having a bit of an issue connecting to SQL SERVER remotely from Windows. I've verified that all of my settings are correct via SQL SERVER MANAGEMENT STUDIO EXPRESS and SQL SERVER CONFIGURATION MANAGER. I can connect remotely using ODBC drivers from other OSes (e.g. OS X, Linux, etc). However, when I connect with the same credentials from a remote Windows machine using "SQL SERVER" as the driver I am told that the system cannot connect. I've tried creating an ODBC Data Source and I get the same error: Connection failed: SQLState: '01000' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionOpen(InvalidInstance()). Connection failed: SQLState: '08001' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Invalid Connection From the non-windows machines I can use the IP address of the SQL Server just fine. However, on the remote Windows machine, neither IP address nor named instance works. FYI, I can create an ODBC Data Source using the named instance on the machine actually running the SQL Server (but this is, of course, nothing special -- just proof that it isn't completely hosed). One interesting note: If I use SQL STUDIO 2005 from a Windows client machine, I can use the IP address to connect remotely. Still, the whole reason I bring this up is because I need to use a software package I've written to connect to SQL Server remotely from Windows machines as well. Previously the solution was only needed to xfer data from SQL Server into a PostGRES or MySQL database on non-Windows machines (due to DBA preference). However, now they also want to move the data from the legacy software to MySQL even on Windows. Any assistance would be most appreciated. Feel free to provide a full example connection string. Best

• Windows 7 - ignore security when reading external drive

  - by w-

  hi, My system hard drive on an XP computer kind of failed (random corrupt sectors). So i got a new harddrive and am trying to recover the files. The filesystem is NTFS. The system i'm trying to use when recovering the files is Windows 7. I'm obviously an admin on this box. The last data i'm trying to recover is stuff in the Documents and Settings folder. I'm using a SATA to a USB cable thingy so that I just plug it in as an External Hard Drive. The problem: In Windows Explorer when i try to copy the data, I keep getting prompted with Security warnings and error messages. It keeps telling me i have to change the owner permissions of the folder and all it's contents. If i tell it to change all the files and folder permissions it takes a really long time because it has to recurse through all the folder contents to change the permissions. Is there a way for me to ignore the file permissions when doing this? thanks

• Why is my global security group being filtered out of my logon token?

  - by Jay Michaud

  While investigating the effects of filtered tokens on my file permissions, I noticed that one of my global security groups is being filtered in addition to the regular system-defined filtered groups. My Active Directory environment is a single-domain forest on the Windows Server 2003 functional level. I'll call the domain "mydomain.example.com". I am logged onto a Windows Server 2008 Enterprise Edition machine (not a domain controller) as a member of the "MYDOMAIN\Domain Admins" group and the "MYDOMAIN\MySecurityGroup" global security group (among others). When I run "whoami /groups" from an elevated command prompt, I see the full list of groups to which my account belongs as expected. When I run "whoami /groups" from a regular, non-elevated command prompt, I see the same list of groups, but the following groups are described as "Group used for deny only". BUILTIN\Administrators MYDOMAIN\Schema Admins MYDOMAIN\Offer Remote Assistance Helpers MYDOMAIN\MySecurityGroup Numbers 1 through 3 above are expected based on Microsoft documentation; number 4 is not. The "MYDOMAIN\MySecurityGroup" global security group is a group that I created. It contains three non-built-in global security groups, and these security groups contain only non-built-in user accounts. (That is, I created all of the accounts and groups that are members of the "MYDOMAIN\MySecurityGroup" global security group.) There are other, similar groups of which my account is a member that are not being filtered out of my logon token, and this group is not granted any specific user rights in the security settings of this computer or in Group Policy. What would cause this one group to be filtered out of my logon token?

• How can I read PDFs with e-reader on a Lenovo tablet?

  - by Jack M

  This is my first time using a tablet and I'm totally lost - this must be what computers look like to old people. This is a Lenovo Thinkpad tablet. I don't see a specific model number on it (it was passed down to me second hand). What I'd like to do is read a PDF. I'm fairly certain I successfully transferred the PDF onto the tablet via an SD card, and I noticed this thing has an app called "eReader" on it, so I started that up. All I see are empty bookshelves, and no obvious buttons or settings anywhere. I saw in multiple places that you have to, as one site puts it: ...copy and paste the relevant files into the eBooks folder and they will appear on the eReader shelf for your consumption... But I have no idea how to: Access the file system. Locate the eBooks folder. Copy and paste files. Will I need a file explorer app? If so, how can I install that given that my only method of getting data onto this tablet is an SD card (no wireless internet).

• Stronger laptop_mode in Linux

  - by Vi

  Can I have stronger laptop mode in Linux? I want to spin down the hard drive and prevent it to spin up even if something wants to read something not in cache. In general I want to have these modes: Normal Current laptop mode Stronger laptop mode: spin up only when needs to read something uncached (and cache it). No spinups to write something unless really memory pressure (Exception: explicit "sync" command in console). Kernel is allowed to keep processes in D-sleep for 10 seconds for that. Forced laptop mode: do not spin up, period. Keep offending processes in D-sleep unless I turn off this mode. Like there is a bomb instead of hard drive. I also want to have access times tracked (mount -o atime), but I don't want the hard drive to be spinned up only to update them. Is there some settings or kernel patches that can get closer to this? May be I should write special io scheduler for "forced laptop mode"? E.g. echo suspend > /sys/block/sda/queue/scheduler to lock the drive and echo cfq > /ys/block/sda/queue/scheduler to unlock it again?

• How to perform this Windows 7 permissions change on many files via GUI or command line

  - by hippietrail

  After using my external hard drive on another Windows 7 computer to tweak photos with Windows Live Photo Gallery then upload them to Facebook I found the modified images were now not visible on the original Windows 7 computer. I'm not sure if the things I tried to get it working subsequently changed anything, but I do know this is the sequence of actions that makes the permissions of the modified files match those of the unmodified files: Right click on broken image file, select "Properties" On the "Security" tab press the "Advanced" button In the "Permissions" tab press the "Continue" button with the shield icon on it Tick the box marked "Include inheritable permissions from this object's parent Click the "Remove" button to remove the only current entry "Type: Allow, Name: Administrators (XYZ\Administrators), Permission: Full control, Inherited From: OK on the "Permissions" tab. OK on the "Security" tab. Now this same procedure does not work at the folder level. It results in "access denied" dialogs. I'm looking for some way to perform this exact modification on all the images I edited on the other computer. I'm happy to use the Windows GUI in Explorer or any other included tools. I'm happy to use the Windows command line. I'd prefer not to use a third-party tool since I'd have to be satisfied it's not doing anything else. I'm not looking for a different way to change permissions to other settings to make an external drive full of photos editable on multiple computers. At least not in this question.

• How do I set up Grub properly to quad-boot Windows, Mac OS X, Linux, and FreeBSD?

  - by Joe

  Grub has gone completely insane on me. My quad-boot system was working great up until I upgraded Ubuntu to 12.04. Since Ubuntu overwrote the Grub stuff I had to repair it with my Mac OS X and FreeBSD entries. After this, trying to boot Mac OS X gave me the error "couldn't open file" and FreeBSD gave the error "no such partition". Windows and Ubuntu worked fine. So I tried repairing again because I figured something must've gone wrong in the install process. Then only Ubuntu would boot. Trying to boot Windows would give me the error "no argument specified". I tried repairing Grub once again, since I seemed to be getting different results each time. This time, Ubuntu no longer appeared in the Grub menu, and the errors for the other OSes were the same. So I booted into the Ubuntu 12.04 live CD and ran Boot-Repair with recommended settings. Now Grub is completely skipped and Windows boots up. I have absolutely no idea what is going on or why I get different results every time I reinstall Grub. Here is how my partitions are set up: sda1 - Storage drive, sdb1 - Windows, sdb2 - Mac OS X, sdb3 - FreeBSD, sdb4 - Extended, sdb5 - Ubuntu, sdb6 - Shared storage, sdb7 - Shared Storage, Here's my grub.cfg file: grub.cfg

• Window too big to fit the screen!

  - by syockit

  I'm using Windows 7 on a 8.9' monitor with 1280x768 screen resolution. Using the might of arithmetics, I'm able to determine that my dpi (actually ppi) should be 167. Win7 is really helpful in that it doesn't have to restart to apply new dpi settings, unlike its predecessors (though I'd rather it applies straight away). The problem with small monitors in Windows is that when you come across windows too big to fit the screen, you can't move the title bar far above it. In X window managers I used in the past, you could alt-drag the window to anywhere you want, but in Windows, even if you alt-space and select move, it will automatically push the window back until the title bar is visible. I'm looking for a solution that either: allows me to move window freely without regard to titlebar visibility, or attach a scrollbar to existing window, or EDIT: create virtual desktops that allow me to span windows over 2 desktops, or EDIT 2: allow me to set larger virtual resolution, then pan & scan. EDIT 3: I found some progs that might do some of the above: 1) AltDrag allows me to drag, resize using alt and left/right mouse button. Neat! Best solution so far. 2) GiMeSpace Desktop Extender is supposed to allow me to scroll desktop. Didn't work. The other new version, GiMeSpace Ultimate Taskbar worked, but it destroys my Superbar, replacing it with its map.

• Upgrade or replace?

  - by Felix

  My current PC is about four years old, although I have made upgrades to it throughout its existence. The current specs are: (old) Intel Pentium D 2.80Ghz (32K L1 / 2M L2), Gigabyte 945GCMX-S2 motherboard (old) 2.5GB DDR2 (slot0: 512MB @ 533Mhz; slot1: 2GB @ 667Mhz) (new) HIS Radeon HD 4670 - I think this is limited by the motherboard not supporting PCIe 2.0 (?) (old) WD Caviar 160GB - pretty slow (new) WD Caviar Black 640GB (if any more specs are relevant, let me know and I'll add them) Now, on to my question. I've been having performance issues lately, both in video games and in intensive applications. A couple of examples: Android application development (running Eclipse and the Android emulator) is painfully slow (on Linux). I only realized this when, at my new job as an Android dev, both tools are MUCH quicker. (I'm not sure what CPU I have there) The guys at my new job got me NFS Hot Pursuit, in which I barely get like 5-10FPS, even with graphics options turned all the way down My guess is that the bottleneck in my system is my CPU, so I'm thinking of upgrading to a Quad Core i5 + new motherboard + 4GB DDR3 (or more, 'cause I know you'll all jump and say 8GB minimum). Now: Is that a good idea? Is my CPU really a bottleneck, or is the whole system too old and I should replace it? I run Windows 7 on the old, 160GB HDD (which is on IDE, by the way). Could this slow down games as well? Should I get a new drive for Windows if I want to play new games? I know nothing about power supplies. Could that be a problem / will it be a problem if I upgrade to an i5? How come DiRT2 works on full graphics settings (pretty amazing graphics by the way) and NFS Hot Pursuit pulls only 5-10FPS?

• How to install (old) packages for Ubuntu 9.04?

  - by wchrisjohnson

  Based on some excellent feedback by Mark here (http://serverfault.com/questions/285598/should-i-clone-a-physical-server-to-create-a-vm-for-a-staging-server), today I was able to use the vmware converter to clone my production server for a staging server. However the nic won't come up no matter what I do. I attempted to inistall vmware tools, as I suspect that the fact that it is not installed might prevent the nic from working. (I have the nic set as a vmxnet3 card in the vm settings). The install failed because there were several dependencies missing as well as the Linux headers. Given that Ubuntu 9.04 has been EOL'd, the packages I need to install to get the vmware tools to install are no longer available. I doubt the ubuntu 9.04 install CD has the packages on it. What are my options? I'd rather not upgrade the version of Ubuntu yet, as the point of the vm right now is to maintain parity with the production server. Might I have better luck resetting the driver to use vmxnet2 instead of the vmxnet3? Thanks in advance! Chris

• Windows 7 does not detect my new hard drive?

  - by jasondavis

  I just built a really nice new PC. Some specs... Intel i7-930 CPU ASRock Extreme X58 motherboard with sata 3 and USB 3.0 12gb of G-Skill DDR3 RAM 80gb Intel G2 Solid state drive for Windows 7 and other programs to run on Windows 7 Pro 64bit OS 2 1gb grapghic cards for 4 monitor support Thats the main components. Well today my new 1tb western digital hard drive came which I plan to use for data to preserve the life of my SSD (hopefully). I hooked up it's sata power input and then hooked up it's sata data cable to a sata 2 port on my motherboard, I boot windows 7 and go into my computer and the drive is not showing up with my other drives. I then re-boot again and check again, no luck. I then shut down the PC and open the case back up, I then check my connections and they all look good. I then boot up and I can see the new HD is on and spinning. I then go into my BIOS settings to see if it registers there and it DOES! It shows I have a WD 1tb hard drvie on sata 2 port 6. So I am at a loss of why it is not showing up as an option in windows? Windows acts as if the drive is not there. Please help

• Windows 7 not booting up and stuck at startup repair

  - by mikimr

  I've been having issues with Windows 7 Home Premium on a Lenovo laptop. At first, it would not start up normally at all. I started it in Safe Mode, where I disabled all non-MS services and tried again to no avail. It then goes into Startup repair where it failed several times. I tried copying the original registry settings, still the same. I resorted to booting with an Ubuntu DVD, where I ran the boot-repair, where it is supposed to correct the Windows boot. No luck. I used Win7 DVD to start up from there, where I had the option to install or repair. I chose the repair, got into command prompt, ran chkdsk /i /r, where it found 3 unreadable segments, went through the 2nd step without issues, and the 3rd step completed with some errors (can't recall the exact errors). When I restarted the machine, it went to straight to the Stratup Repair, indicating "Attempting repairs... Repairing dis errors. This might take over an hour to complete." It's been like this for nearly 15 hours. When I try to cancel or close the Startup Repair window, I get a message "The current repair operation cannot be cancelled." Should I let it run or force shut the machine? If force shut, how can I resolve this problem? Thanks.

• iPhone 3G can't see any WiFi networks, ever

  - by torbengb

  I've got WiFi turned on in the settings, and ask before connect turned off. My iPhone 3G should see several WiFi networks, but it lists none. It also does not list my own network, which my computers see just fine. It has worked earlier but stopped working recently (possibly because of or at the same time of other trouble (which a restore solved)). The iPhone is not jailbroken. The SSID is not hidden, uses WPA2. It also finds no WiFi networks when I'm at a friend's house. His iPhone 2G sees several WiFi networks, including his own. When I use the manual entry method, specifying my home SSID and the proper WPA2 passkey, then click join, the iPhone says couldn't find that network. Same at my friend's place, with his SSID and passkey. I've just backed up my iPhone, then restored it, to see if refreshing the firmware would help. It didn't change anything. Is my iPhone broken? How can I fix this?

• HSphere - Only sees Apache 2 Test Page after forced shutdown?

  - by Darkwoof

  Hi, I have a dedicated server running on a Dell PowerEdge 850 with CentOS 4.4 and HSphere 3.0 Patch 6 colocated at a datacenter. Last night my hosting company had to schedule a change in the power bar, and I gave the go ahead for them to shut down the server and bring it up when they are done. Since they do not have admin access to the machine, I suppose they did a forced shutdown. When the machine was brought up, I found that all my domains (and sub-domains) are now pointing to an "Apache 2 Test Page" instead of the pre-configured sites that were running prior to the shutdown. This apparently only affects the standard sites running on port 80 - my Webmin instance running at port 1000 is still accessible for example, as well as my HSphere control panel running at port 8080. I've checked the config settings using the HSphere UI for each of the sites, and didn't find anything wrong. I've also tried rebooting the server via SSH, which does not rectify the problem. I've previously done reboots with no issues; the sites would just come right back up when its done, but not this time. I'm guessing some configuration file got corrupted or overwritten this time? Anyone with experience with HSphere and can provide some advice on what's happened and how to solve it? Thanks. (I do not have an active support agreeement for HSphere since Parallels took over and increased the min. license to 200. I only had 25 license for use by family and friends.) Thanks in advance.

• Linksys SFE2000 Interface

  - by boburob

  I have a real problem with a layer 3 Linksys switch. First, every time it looses power, it seems to reset back to an older config. Not only this, but when this happens it looses interface settings on one subnet. This would not be a problem but I am completely unable to get to the interface on the working side. It allows me to log on and then just displays a blank screen. I have tried this on: IE6 IE7 IE8 IE9 Firefox 3.5 Opera Chrome All with the same results, except for Opera, which loads half the interface but nothing I can really use. I really need to get onto this switch so I can sort out routing and VLAN tagged ports, so if anyone has any ideas on either of these issues please let me know ASAP! Thanks! Also, due to its location and my lack of laptops with serial connections I cannot putty into it. UPDATE: Looked into this a bit more and it looks like this model of switch does not save the current config to boot unless you make sure to save it yourself, which explains the first issue, however the broken interface is more worrying!

  - by geerlingguy

  I am behind a corporate proxy server/firewall, and this firewall seems to not be too happy with my idea of local development. On my home computer (Mac/Leopard), I have MAMP running, with a rule in /etc/hosts that directs dev.example.com to 127.0.0.1, and I have a virtualhost set up in the httpd.conf file which works great for me. However, at work, I set up the exact same configuration, but am not able to access dev.example.com, likely due to some address/DNS translation going on via the proxy server. Here are the relevant details from Terminal: $ ping dev.example.com PING dev.example.com (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.025 ms $ host dev.example.com Host dev.example.com not found: 3(NXDOMAIN) I've tried adding dev.example.com to the list of bypass addresses in System Preferences (the 'Bypass proxy settings for these Hosts & Domains' list), but that had no effect. Is there any way I can develop locally using name-based hosts at work? I can access localhost, but can't get to the dev.example.com (or any other custom virtualhosts) here at work, which complicates other matters related to the sites on which I'm working...

• How do I speed up and cache mmap file access over NFS on Linux?

  - by Zan Lynx

  The server and client are both 64-bit Ubuntu 10.04 LTS. The application in question is a custom app that uses mmap() for fast random file access. Its ideal state is when the entire file is cached in RAM. The network connections are really fast 10Gb Ethernet. It is a virtual server blade setup. It isn't the network connections slowing things down because everything performs superbly when using a virtual disk (iSCSI to the SAN). But when we run the application on a NFS home directory mount, performance goes to the dogs. It appears that the Linux kernel isn't caching anything. So it is reading every single disk block needed by mmap() accesses over and over and over again. The NFS mount is done through autofs, which has only default settings. /proc/mounts shows the NFS mount is done with the following options: rw,relatime,vers=3,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.11.52,mountvers=3,mountproto=tcp,addr=192.168.11.52 How can I make Ubuntu 10.04 cache the file instead of reloading it all the time?
