• Converting software RAID1 to RAID10 for /boot

  - by luckytaxi

  Array info: /dev/md0 - /dev/sda1 and /dev/sdb1 /dev/md2 - /dev/sda2 and /dev/sdb2 Partition info: /boot - /dev/md0 / - /dev/md1 I have two drives that are setup as RAID1 using software RAID on Redhat. I added two additional drives (same size) and I would like to conver the RAID1 to a RAID10. The problem I'm having is adding the last drive to the array. I've gotten as far as creating a RAID10 with two missing devices but as soon as I add the last drive, all hell breaks loose. It seems /dev/sda1 is the culprit. What I'm not too sure about is how to create the RAID10. I've tried the following mdadm --create /dev/md2 --level=raid10 --raid-device=4 /dev/sdc1 missing /dev/sdd1 missing I then proceeded to fail /dev/sdb1 from /dev/md0 and added that partition to /dev/md2. I proceeded to install the MBR on EACH partition since boot resides on /dev/sdx1 on each drive. As a test, all is well, I'm able to boot back into the system once I do a quick reboot. Now, when I go add the last drive /dev/sda1, it breaks. I attempted to install grub on /dev/sda1 and I get the following ... grub> root (hd0,0) /dev/sda root (hd0,0) /dev/sda Filesystem type is ext2fs, partition type 0xfd grub> setup (hd0) setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 2: Bad file or directory type At this point, the array is hosed I believe. I rebooted the server and it refuses to boot.

• WRT54GL Tomato Router in Client wireless mode to an iPhone Personal Hotspot

  - by Gordo

  I am trying to connect a router with Tomato firmware to an iPhone 4. The goal is to connect to the Personal Hotspot in Client Wireless mode. This should allow wired and wireless users to connect to the router rather then the iPhone. In theory this should be possible but I am having difficulty. Router Linksys WRT54GL Tomato 1.28.1816 firmware iPhone iPhone 4 iOS 5.1 (9B176) Carrier Rogers Wireless Personal Hotspot works with other devices, wifi/bluetooth/usb iPhone Personal Hotspot settings Mode: B/G Security: WPA or WPA2 Personal Encryption: AES Router IP: 172.20.10.1 Subnet: 172.20.10.0 Min IP: 172.20.10.2 Max IP: 172.20.10.14 maximum number of wireless tethered hosts is 5 I have followed the directions here: http://www.wi-fiplanet.com/tutorials/article.php/3810281 Ensured that the router subnet does not 'collide' with the iPhone subnet. Here is the configuration of the Tomato 'Basic - Network - Wireless' section: http://i.stack.imgur.com/pbmTB.png I have tried several variations of this configuration, but nothing seems to work. NOTE: I have successfully connected to my own wifi network in Wireless Client mode, so I am confident that there are no bad cables or other hardware issues. I would prefer to use Tomato, but DD-WRT maybe my only other option. Thanks!

• Installing Windows 7 over PXE, preferably with domain autojoin

  - by Ivan Vucica

  At an educational non-profit, I've inherited a previously set-up Windows domain that, after the first reinstall of the machines, we ended up not using by simply not joining machines back into the domain. Over last summer, before the annual reinstall for shipping machines to the summer school, I toyed with the idea of installing Windows 7 over network, instead of just imaging the machines. It took a bit longer than I expected to figure out the basics; honestly, I expected that Windows would be more friendly for PXE installation out of the box. What I'm interested in is best practices for installing Windows 7 over PXE with domain autojoin. I'd love it if the whole setup could optionally be hosted on a UNIX based system as well. I've had some success by preparing an ISO using Windows Deployment Kit, and loading the ISO into memory. This was needed since I wanted a menu, and I think I couldn't get PXELINUX to chainload into Windows' bootloader. Unfortunately, I couldn't figure out much about customization of the Windows setup in that timeframe nor could I get Samba to work properly; studying the stuff ended up being too lengthy, especially the portion where I edited a disk image on Windows and copied it outside. WDK didn't make things easier by mounting the disk image into RAM, and writing it in its entirety when done with it, making me a very sad boy. I've recently found a different approach, too, that appears to be closer to Microsoft's original idea for netboot deployment and does not involve ISOs. So my question boils down to the following. What exact approach do you use for netbooting Windows 7 setup? How can Windows 7 setup be best customized to be completely unattended, including installation on specific system partition and not destroying the data partition, creation of passworded admin and default user, choice of MAC-address-based hostname, and joining a domain? As much details as possible for everyone's future reference would be appreciated. WDS isn't a bad choice, but if a Linux-based install can be used, that'd be better.

• Home Sharing and Remote on iTunes causing firewall nags

  - by BoltClock

  It seems that enabling Home Sharing and/or hooking up my iPhone's Remote to iTunes causes Mac OS X Snow Leopard's firewall to freak out and keep nagging every time I launch iTunes to ask if I'd like it to accept incoming connections. If I turn off Home Sharing and forget all Remotes, the nag dialog no longer comes up. I could also disable the firewall, but I think that's a silly thing to do. iTunes is already in the firewall whitelist, so the only thing I know that could cause Mac OS X to nag is a bad application bundle code signature. I checked with this Terminal command: $ codesign -vvv /Applications/iTunes.app/ And sure enough, this is what it outputs: /Applications/iTunes.app/: a sealed resource is missing or invalid /Applications/iTunes.app/Contents/Resources/English.lproj/AutofillSettings.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/iTunesDJSettings.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/MobilePhonePrefs.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/MobilePhoneSetup.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/UniversalAccess.nib/objects.xib: resource added I've tried reinstalling iTunes as suggested by this answer, but Mac OS X still nags about incoming connections and the exact same output is generated when I run the above command again. On my PC, Windows Firewall has never nagged whenever I turn on Home Sharing and hook up Remote on my iPhone. Both computers use iTunes 9.2.1. My Mac runs Mac OS X 10.6.4. Is there anything special I need to do that I might have missed? Or how do I resolve the issue? EDIT: I've updated to iTunes 10, but the nags on my Mac are still there and only go away if I turn off Home Sharing and Remote. EDIT 2: I've updated to Remote 2.0 on my iPhone, but the firewall nags are persisting. Has anyone else had this firewall issue at all?

• Optimal video resolution and encoding for recording games for YouTube?

  - by Rookie

  I want to record video from games, therefore I cannot use very large video resolution, but I still want to make the large video view to look as sharp as the original encoded video before upload. I tried to use YouTube's recommended 854x640 resolution, but it wasn't possible with h264 and the encoding software I used (Handbrake) converted it to a width of the nearest multiple of 4, which I think is a limitation of the h264 format. The video I encoded was sharp and fine quality, but when I uploaded it to YouTube, it lost a lot of quality and the preferred large video view looks almost as bad as a 320p video. I tried to wait a few days but it never got sharper (in case it didn't process it completely yet). So, which resolution and encoding options I should use, if I want the large video player to have the sharpest possible video, retaining the original video quality as good as possible? I noticed that recording with 640x480, the video was sharper than with 1280x720, so I'm not sure what im doing wrong here; both were h264. Is it anyhow possible to prevent YouTube from re-encoding the videos? I just wonder how people can make so sharp videos, while mine are all blurry after upload, but before upload they looked fine. I also tried YouTube's suggested bitrates with h264, but it didn't work any better.

• ORA- 01157 / Cant connect to database

  - by Tom

  Hi everyone, this is a follow up from this question. Let me start by saying that i am NOT a DBA, so i'm really really lost with this. A few weeks ago, we lost contact with one of our SID'S. All the other services are working, but this one in particular is not. What we got was this message when trying to connect ORA-01033: ORACLE initialization or shutdown in progress An attempt to alter database open ended up in ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' I tried to shutdown / restart the database, but got this message. Total System Global Area 566231040 bytes Fixed Size 1220604 bytes Variable Size 117440516 bytes Database Buffers 444596224 bytes Redo Buffers 2973696 bytes Database mounted. ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' When all continued the same, I erased the dbf files (rm xxx_data.dbf xxx_index.dbf), and recreated them using touch xxx_data.dbf. I also tried to recreate the tablespaces using `CREATE TABLESPACE DATA DATAFILE XXX_DATA.DBF` and got Database not open As I said, i don't know how bad this is, or how far i'm from gaining access to my database (well, to this SID at least, the others are working). I would imagine that a last resource would be to throw everything away, and recreating it, but I don't know how to, and I was hoping there's a less destructive solution. Any help will be greatly appreciated . Thanks in advance.

• Multiple *NIX Accounts with Identical UID

  - by Tim

  I am curious whether there is a standard expected behavior and whether it is considered bad practice when creating more than one account on Linux/Unix that have the same UID. I've done some testing on RHEL5 with this and it behaved as I expected, but I don't know if I'm tempting fate using this trick. As an example, let's say I have two accounts with the same IDs: a1:$1$4zIl1:5000:5000::/home/a1:/bin/bash a2:$1$bmh92:5000:5000::/home/a2:/bin/bash What this means is: I can log in to each account using its own password. Files I create will have the same UID. Tools such as "ls -l" will list the UID as the first entry in the file (a1 in this case). I avoid any permissions or ownership problems between the two accounts because they are really the same user. I get login auditing for each account, so I have better granularity into tracking what is happening on the system. So my questions are: Is this ability designed or is it just the way it happens to work? Is this going to be consistent across *nix variants? Is this accepted practice? Are there unintended consequences to this practice? Note, the idea here is to use this for system accounts and not normal user accounts.

• Authority Information Access local path being ignored

  - by Kevin

  I have a CA set up in Server 2008 R2, and generally it is working, but I can't control the local path/filename it writes its own certificate to for the Authority Information Access publishing. Here's a screen shot of the dialog I'm trying to set this on: From these settings I would expect to get the file: C:\Windows\system32\CertSrv\CertEnroll\DAMNIT.crt But instead I get: C:\Windows\system32\CertSrv\CertEnroll\SERVER.domain.com_My Issuing Authority(1).crt Of course, the actual change shown wouldn't be very useful, but it's illustrative; no matter what path/filename I use, it always lands up in the same place and with the same name. I actually wanted to change the name from <ServerDNSName>_<CaName><CertificateName>.crt to <CaName><CertificateName>.crt, since the latter corresponds to the HTTP URL whereas the former does not. Admittedly, I haven't set up many CAs so perhaps I'm just deluded as to what this dialog is supposed to be setting, but if so this is notoriously bad UI design. (Incidentally, I have a couple other complaints with the same dialog.) What's going on here and is there some way to get the filename pattern I want?

• background jobs and ssh connections

  - by petrelharp

  This question has come up quite a lot (really a lot), but I'm finding the answers to be generally incomplete. The general question is "Why does/doesn't my job get killed when I exit/kill ssh?", and here's what I've found. The first question is: How general is the following information? The following seems to be true for modern Debian linux, but I am missing some bits; and what do others need to know? All child processes, backgrounded or not of a shell opened over an ssh connection are killed with SIGHUP when the ssh connection is closed only if the huponexit option is set: run shopt huponexit to see if this is true. If huponexit is true, then you can use nohup or disown to dissociate the process from the shell so it does not get killed when you exit. If huponexit is false, which is the default on at least some linuxes these days, then backgrounded jobs will not be killed on normal logout. But even if huponexit is false, then if the ssh connection gets killed, or drops (different than normal logout), then backgrounded processes will still get killed. This can be avoided by disown or nohup as in (2). There is some distinction between (a) processes whose parent process is the terminal and (b) processes that have stdin, stdout, or stderr connected to the terminal. I don't know what happens to processes that are (a) and not (b), or vice versa. Final question: How can I avoid behavior (3)? In other words, by default in Debian backgrounded processes run along merrily by themselves after logout but not after the ssh connection is killed. I'd like the same thing to happen to processes regardless of whether the connection was closed normally or killed. Or, is this a bad idea?

• Best usage for a laptop being used as a desktop without removable batteries

  - by Senseful

  After reading the information on http://batteryuniversity.com, I realize that one of the best ways to permanently damage a lithium ion battery is to use the battery at a high temperature while it's fully charged. This is exactly what happens when you use the computer as if it were a desktop computer, since leaving it plugged in will keep the battery at 100% and using the computer will heat up the battery. This is why it's recommend to remove the battery from your laptop if you are using it is this scenario. My question is what would you do if the laptop doesn't have removable batteries (e.g. a MacBook Pro)? Should I use some kind of charge cycle such as: charge to 80%, unplug the power chord, use the laptop until it reaches 20%, then repeat the cycle by charging to 80% again? If so, which values should I use instead of 80% and 20%? (I think charging to 80% is better than 100% because of the damage that a hot battery at 100% can do, but I just made the figure 80% up, and I'm sure there's a better number to strive for which is backed by science.) I've read many of the articles on batteryuniversity.com, but couldn't find anything pertaining to this. Update: What about doing something like charge (or discharge) it to 50%, then plug it in and turn on settings which use the battery as much as possible (e.g. brightness all the way up, wi-fi on, etc.), in order to try to maintain the battery at 50% (i.e. the rate it is charging is the same as it is discharging). This will probably heat up the battery, but would make it so you don't need to constantly plug and unplug the laptop. The one bad thing is that you are taking up more charge cycles which would decrease the battery life, thus I'm not sure this is a good idea.

• Most cost efficient way to backup Subversion data to S3?

  - by sludge

  I'm looking at using S3 as an offsite backup repo for my Subversion database. When I dump my SVN database, it's about 10 gigabytes. I would like to avoid the charge of uploading that data repeatedly. The anatomy of this large file such that new changes to Subversion modify the tail of the file, with everything else staying the same. Because Amazon S3 does not allow you to "patch" files with changes, I will have to upload ten gigs every time I instantiate a backup after doing a simple submit to Subversion. Here are the options as I see them: Option 1 I am looking at duplicity which has --volsize which splits data over an amount of megs. Is it possible to split the Subversion dumps using this so further incremental backups are measured in megabytes? Option 2 Can I just backup the hot subversion repository? This seems like a bad idea if it is in the middle of writing a submit. However, I have the option of taking the repo offline between the hours of midnight and 4am. Each revision in my Berkeley DB uses a file as its record.

• Why we can change our IP address?

  - by iamstupid

  I across some websites that offer change of our IP addresses. It says, we can surf net anonymously, including changing our IP address and location. Most of the softwares are not free, so I have not try it out yet. But my question is, so, IP addresses will no longer be unique or valid for identify which computer were sending/request the information? I though only the ISP can determine our IP, so we can change our IP from some commercial softwares huh? Case: If I change my IP address, I go to a website which is supposed to be banned by my country, will the ISP let me pass the check and I will be able to browse the website which should be blocked? another question: From what I know, if we want to go to certain website, here is the flow: My Computer = ISP = Website = ISP = My computer I am not sure, if its the correct flow, but I am sure that, whichever website I want to visit, I need to go through my ISP, isnt it?. So if we change out IP, our ISP will record our new IP or the original(assigned-by-ISP) IP? Sorry for my bad English.

• Apache reports a 200 status for non-existent WordPress URLs

  - by Jonah Bishop

  The WordPress .htaccess generally has the following rewrite rules: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> When I access a non-existent URL at my website, this rewrite rule gets hit, redirects to index.php, and serves up my custom 404.php template file. The status code that gets sent back to the client is the correct 404, as shown in this HTTP Live Headers output example: http://www.borngeek.com/nothere/ GET /nothere/ HTTP/1.1 Host: www.borngeek.com {...} HTTP/1.1 404 Not Found However, Apache reports the entire exchange with a 200 status code in my server log, as shown here in a log snippet (trimmed for simplicity): {...} "GET /nothere/ HTTP/1.1" 200 2155 "-" {...} This makes some sense to me, seeing as the original request was redirected to page that exists (index.php). Is there a way to force Apache to report the exchange as a 404? My problem is that bogus requests coming from Bad Guys show up as "successful requests" in the various server statistics software I use (AWStats, Analog, etc). I'd love to have them show up on the Apache side as 404s so that they get filtered out from the stat reports that get generated. I tried adding the following line to my .htaccess, but it had no effect (I'm guessing for the same reason as the previous redirect rules): ErrorDocument 404 /index.php?error=404 Does anyone have a clever way to fix this annoyance? Additional Info: OS is Debian 6.0.4, and Apache version looks to be 2.2.22-3 (hosted on DreamHost) The 404 being sent back to the client is being set by WordPress (i.e. I'm not manually calling header() anywhere)

• Laptop Most Likely to Have Good Driver Support

  - by ShabbyDoo

  Through numerous bad experiences, I have learned that the most likely cause of laptop "failure" is the lack of updated drivers for new operating systems. As an example, I have a perfectly good Thinkpad T42 at home which runs Windows 7 just fine for my purposes except that no compatible ATI video drivers are available, and the generic drivers have flicker effects. I recently saw an ASUS laptop which looked quite nice except that I would be beholden to them to release ATI video driver updates customized for it. And, I can't trust them to do that for more than six months. What laptops (manufacturer/line) should I consider so that I could expect at least a couple years of frequent updates? I plan on running Windows 7 and installing whatever successor comes out. I like Intel components (especially WiFi) because I can install their drivers directly from them, and they have a long history of providing updates for years after shipping a particular component. More generally, components from companies which are likely to update drivers frequently are good as long as I can install the component manufacturer-provided drivers without laptop-specific customization (like the ATI drivers). Also, if a component can be replaced easily, I am less concerned. For example, Dell stopped pumping out updated drivers for one of its mini-PCI WiFi cards. The solution was to buy an Intel replacement on eBay for $12! That's fine. I can deal with that. So, what laptops should I consider so that I'm not likely to be stuck between a rock and a hard place?

• Two Firefox windows vs two browsers? Ram Consumption

  - by Kayle

  I don't know enough about Ram & sharing to know what the difference is here. Normally, I run Chrome in one desktop for personal use, and Firefox on a second desktop for business. I like the separation of saved passwords and whatnot. However, I recently learned that I can open two different profiles in Firefox at the same time, so I was wondering if that would be cheaper to my system resources, or not? Out the door, I don't think it would save more than 40-60mb of ram... but I'm wondering, 3 hours later, if ram handling will be better using just one browser for all my heavy lifting. I only have 2gb of ram and I run iTunes and Photoshop as well, almost all day. So I like to save ram where I can. Any thoughts? UPDATE: I've been centering around chrome more recently and using firefox for testing. Dev isn't bad on Chrome and it's great at releasing memory when I close tabs. In retrospect, I think the best answer to this question is simply for me to buy another 2gb of ram.

• How can I backup entire installations of a program, instead of just manually backing up individual f

  - by NoCatharsis

  It seems pretty straightforward to backup individual files, such as pictures, saved games, or settings files - just copy them straight over to your 2nd HDD or to an online service like DropBox. However, is there any way to backup entire installations of a program? For instance, my Firefox directory has a lot of personal customizations and add-ons. I don't want to go through each item and decide to back it up or let it go. So my next option is to copy out the entire directory for backup. But, if I copy the entire directory back onto the HD after a format, it is not an integrated installation and this seems like it could be troublesome. I would assume Windows cannot detect the directory for uninstallation, or would not let you choose Firefox as your default browser, right? I'm no pro, but this sounds like a bad idea. So my question is whether there is a good way to preserve all necessary files, while also preserving the full installation process of an application. This is not specific to Firefox - I would like to know how to do this for any application. Thank you.

• Can't find gnutls ibrary when executing rpmbuild under non-root

  - by Rilindo

  I am trying to build ntgs from the latest source, using the .spec from rpmforge - as non-root via rpmbuild. During the compile, it fails at this step: checking for GNUTLS... no configure: error: ntfsprogs crypto code requires the gnutls library. error: Bad exit status from /var/tmp/rpm-tmp.78913 (%build) However, I can compile it successfully outside of rpmbuild. So it sounds like it just the matter of library being seen during the build. However, I can confirm that rpmbuild can see the library that gnutls resides: [foo@bar ~]$ rpmbuild -E '%{_libdir}' rpmbuild/SPECS/ntfsprogs.spec /usr/lib Library location: [foo@bar ntfs-3g_ntfsprogs-2012.1.15]$ /sbin/ldconfig -p | grep -i gnutls libgnutls.so.13 (libc6) => /usr/lib/libgnutls.so.13 libgnutls.so (libc6) => /usr/lib/libgnutls.so libgnutls-openssl.so.13 (libc6) => /usr/lib/libgnutls-openssl.so.13 libgnutls-openssl.so (libc6) => /usr/lib/libgnutls-openssl.so libgnutls-extra.so.13 (libc6) => /usr/lib/libgnutls-extra.so.13 libgnutls-extra.so (libc6) => /usr/lib/libgnutls-extra.so What would cause the problem of the library not being seen when you build a RPM?

• Linux VLAN Bridge

  - by raspi

  I have home network with VLANs, one for LAN, one for WLAN and one for internet. I'd like to use bridging so that instead of configuring these same VLANs to every machine, they had own VLAN ID and bridges were LAN, WLAN and internet. I've tried it but for some reason keep-alive/ttl seems to get broken because SSH sessions etc suddenly disconnects. We have this same setup working in workplace for 4+ years with 100+ customers but it's custom firewall/router hardware so accessing it is impossible. I know that it runs Linux. So what is Debian/Ubuntu default network settings doing wrong or is it just NIC driver/hw problem? I've tried to mess araund with ttl etc settings without any luck. The bad stuff is happening in the bridge because current VLAN-only setup works fine. interfaces: auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 allow-hotplug eth1 iface eth0 inet static iface eth1 inet static auto vlan111 auto vlan222 auto vlan333 auto vlan444 auto br0 auto br1 auto br2 # LAN iface vlan111 inet static vlan_raw_device eth0 # WLAN iface vlan222 inet static vlan_raw_device eth0 # ADSL Modem iface vlan333 inet static vlan_raw_device eth1 # Internet iface vlan444 inet static vlan_raw_device eth0 # LAN bridge iface br0 inet static address 192.168.0.1 netmask 255.255.255.0 bridge_ports eth0.111 bridge_stp on # Internet bridge iface br1 inet static address x.x.x.x netmask x.x.x.x gateway x.x.x.x bridge_ports eth1.333 eth0.444 bridge_stp on post-up iptables -t nat -A POSTROUTING -o br1 -j MASQUERADE pre-down iptables -t nat -D POSTROUTING -o br1 -j MASQUERADE # WLAN bridge iface br2 inet static address 192.168.1.1 netmask 255.255.255.0 bridge_ports eth0.222 bridge_stp on Sysctl: net.ipv4.conf.default.forwarding=1

• IPC between multiple processes on multiple servers

  - by z8000

  Let's say you have 2 servers each with 8 CPU cores each. The servers each run 8 network services that each host an arbitrary number of long-lived TCP/IP client connections. Clients send messages to the services. The services do something based on the messages, and potentially notify N1 of the clients of state changes. Sure, it sounds like a botnet but it isn't. Consider how IRC works with c2s and s2s connections and s2s message relaying. The servers are in the same data center. The servers can communicate over a private VLAN @1GigE. Messages are < 1KB in size. How would you coordinate which services on which host should receive and relay messages to connected clients for state change messages? There's an infinite number of ways to solve this problem efficiently. AMQP (RabbitMQ, ZeroMQ, etc.) Spread Toolkit N^2 connections between allservices (bad) Heck, even run IRC! ... I'm looking for a solution that: perhaps exploits the fact that there's only a small closed cluster is easy to admin scales well is "dumb" (no weird edge cases) What are your experiences? What do you recommend? Thanks!

If you click Yes, any Active Directory changes that have been made on this domain controller will be lost. So, i started to move all the roles to the new server as described here, when all was ok with the roles, i tried doing the same, but got the same result. Tried moving the DNS to the new server, but it doesn't make difference. Shutdown to the old server, then tried to log into a workstation, but it fails saying the domain is not available, also coudln't add new workstation to the domain, so i have to power on the old server again. So, if i successfully move all the roles and dns to the new server: why dcpromo give such message in the old server? why if i shutdown the old server the domain is not available?? if i successfully move all the roles and dns to the new server, and i click yes when dcpromo give warning in the old server, will i lose all users, computers, ou, etc.? am i missing some steps to make this work?? hope you can help me thanks

• Which CPU for XEN - LAMP testbed - Budget

  - by deploymonkey

  Dear serverfault knowledgeables, im in a decision dilemma right now, which I can't resolve due to lack of hands on experience. I need to build a testbed for basically virtualizing a LAMP application (os'ses not yet decided) including server side calculations. I'll opt for XEN since it seems better supported by cloud hosters at the moment. The hardware is for a proof of concept for a startup doing saas and might be used for closed live alpha/beta later on. After testing, the testbed might be a) deployed as a colocated white box server b) used as workstation Single socket is enough. We want to have ECC memory for reliability, this excludes most of the consumer line at intel. If intel CPU, then threaded cpu (HT) is preferred have at least 16 gig ram If justified by price and reliability is not too bad, a high quality desktop MB instead of a server MB would be worth a try It came down to the opteron 6128 vs. the xeon 5620 for me after a lot of research, but I don't necessarily have to be right. Which CPU is preferrable, concerning TCO (MB price, power requirements 24/7...) , Opteron 6128 or Xeon 5620? Which one offers better performance in real world applications? (Do You have any other suggestions I probably overlooked?) Thank You for Your consideration

• Dell Latitude D510 Runs From Battery But Not AC Adapter

  - by Jason George

  I have a Dell Latitude D510 that went belly up around two years ago. It will run from the battery, however, the wall adapter will neither power the machine nor charge the battery. Once the battery is dead, the machine is dead. Since it died I've searched repeatedly for solutions. I've tried a new AC adapter and even removed and replaced the DC jack thinking one of the solder joints might be bad. Both to no avail. After two years of searching I finally found the answer today. Since it's such a simple fix and I had such a hard time finding it I wanted to post the info for others (as it is apparently a common issue with the D510). -----SOLUTION----- It seems this is commonly caused by a cracked solder joint at pin 1 on an inductor filter pair (FL2) near the power jack. Pins 1 and 4 are ground and pins 2 and 3 are power. There should be 20V from 1 to 2 and 3. Anything less indicates a cracked joint that is increasing resistance and dropping the supply voltage. Repair simply requires reflowing all four pins with a little added solder for security. Detailed instructions can be found here. Dell Latitude D510 solder problem

• ubuntu 9.10 installer doesn't recognize the hard drive

  - by dan

  I downloaded Ubuntu 9.10 x86_64 and am trying to install it on a fairly modern system with a Gigabyte GA-MA770-UD3 motherboard. Ubuntu 9.04 installed fine and still will when I stick that disc in, but 9.10 doesn't see my hard drive (western digital 250GB). If I boot from the disc, I can install gparted and it does recognize the drive, but when I try to start the install process from the live disc, Ubuntu again doesn't recognize the hard drive. I checked /var/log/messages and see this: Nov 12 17:28:08 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was bad, boot with 'nodmraid'. Nov 12 17:28:08 ubuntu activate-dmraid: Enabling dmraid support Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. Nov 12 17:28:08 ubuntu activate-dmraid: no raid sets and with names: "nvidia_ciiajheb-0" Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. I checked my BIOS, SATA is enabled and is set to IDE mode, so there shouldn't be software RAID, but nonetheless, I added nodmraid to the boot line and tried again. It still doesn't recognize the drive. I checked /var/log/messages again and now see this: Nov 12 17:49:38 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was boad, boot with 'nodmraid'. Nov 12 17:49:38 ubuntu activate-dmraid: Enabling dmraid support Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option Any ideas on things to try? I've tried all of the various BIOS settings for SATA. IDE,RAID, etc. Nothing seems to work.

• SVN checkout returns 400 error

  - by eboix

  I'm trying to download the http://code.opencv.org/svn/opencv/trunk/ repository of all of the OpenCV source code - as specified in an OpenCV installation tutorial. In the tutorial, the repository https://code.ros.org/svn/opencv/trunk/ is used, but they moved it to http://code.opencv.org/svn/opencv/trunk/, and now you need a password to access the code.ros.org repository. Anyway, I'm using TortoiseSVN to download the SVN repository. (I get the same error with http://sourceforge.net/projects/win32svn/) I get this: Checkout from http://code.opencv.org/svn/opencv/trunk, revision HEAD, Fully recursive, Externals included Server sent unexpected return value (400 Bad request. Method Unknown) in response to REPORT request for '/svn/opencv/!svn/vcc/default' On the TortoiseSVN site I found something about this 400 error: You're behind a firewall which blocks DAV requests. Most firewalls do that. Either ask your Administrator to change the firewall, or access the repository with https:// instead of http:// like in https://svn.collab.net/repos/svn/ That way you connect to the repository with SSL encryption, which firewalls can't interfere with (if they don't block the SSL port completely). Also some virus scanners (i.e. Kapersky) are known to interfere and cause this error. The code.ros.org repository is https://, so I would be able to access it, but I need a password, so I can't. I made an account on ros.org, but it seems that I still need a password (which I don't know) to access the code repository. My username-password combination does not work. I unblocked all of the TortoiseSVN programs in my firewall settings. Nothing changed. I temporarily stopped my firewall to see if it was interfering with my request. I got the same error. How can I do an svn checkout http://code.opencv.org/svn/opencv/trunk/opencv/ so that I don't get this error? Is there any way to make it https://? Any help would be appreciated!
