• Don't break header/footer when making page landscape format

  - by Steeven

  I have a document with a footer with page numbering and a header with some centered text. Long story short: I flipped one page to landscape format. Long story long: I made a forced page break to get a blank page. I then highlighted this page (that is, I highlighted the empty line on this page) and went to the page proporties menu window, clicked on the landscape format button, and chose to apply this setting for the highlighted text only. The result: All that is of course no big deal, and my page is flipped the 90 degrees as wished - but my header and footer break! They disappear from this page... and actually also from the next page (which is still upright portrait format), which is weird. And then the header and footer is back on the following pages again, though the page numbering restarts from 1. On this screenshot you can see that the previous and the following pages have headers and footers, but not the flipped one and not the page following the flipped one. What just happened here? How can I make the page numbering continue without restarting first of all, and then, how can I keep the header and footer on at least the upright page, that suddenly doesn't have them?

• PostgreSQL failover cluster on Windows Server

  - by user36997

  We are looking for advice on how to setup a basic failover cluster for our application: We will be using 4 machines running Microsoft Windows Server (most probably 2003). All four will always run our application, which is essentially a web service. Load balancing is "outsourced" - somebody else handles the distribution of the web requests among the servers. Only one of the servers will be running the PostgreSQL server actively at any given time. Another server (of the four) also has the DB installed, but is on standby/passive. The DB data is stored on shared storage. No copying data between servers. Reads are done very frequently by many end-users, and in rather small chunks of data. Writes are done much less frequently, by less users, and in very large bulks of data. Now, how can one configure Microsoft Cluster Service to keep only one instance of the DB server and 4 instances (1 per server) of our application at all times? And does PostgreSQL integrate neatly with MSCS at all? Update: Instead of keeping the data on shared storage, I also consider using log shipping to replicate data on a couple of DB servers. There are two issues with this option: Log shipping only makes sure that I have a second server that gets all of the data and is ready to take over. How do I implement the actual failure detection and failover switch? Switching back: Suppose the master fails and the system automatically fails over to the slave, and later the master comes back online. I understand that with WAL shipping this will require to reconfigure the log shipping once again, and that switching back is far from seamless. Is that so?

• Upgrading Visio 2000 to Visio 2007

  - by dirtside

  I have Microsoft Visio 2000 SR 1, and recently purchased Microsoft Office Visio Standard 2007 with the understanding (supported by the product info and some other research) that I'd be able to upgrade. However, when I install 2007, it tells me it can't find a previous install of Visio, but... it's right there! Here's the exact message: "Setup can't find a version of Microsoft Office on your computer. If Office is installed on a disk or network share, click the browse button to select the appropriate disk or share... (etc.)" No matter which directory or drive I pick (various Office installs, the old Visio install, various subdirectories) it gives the following message: "The path you have chosen does not point at a qualifying upgradeable product. Click 'Retry' to try again or 'Cancel' to quit setup." Any ideas? This is a legit copy of Visio 2007 (purchased from Amazon) and the copy of Visio 2000 is legit as well. I'm not sure what exactly the installer is looking for that it would consider a "qualifying upgradeable product". A specific file?

• Windows 7 - mysteriously missing free HDD space

  - by sYnfo

  I have Windows7 installed on 50GB (Oops, it should have been 45GB, sorry) partition, and every now and then it gets full, and I have to resize that partition. I always thought it is quite normal. But it happened again today and this time, I'm sure it is not normal, because since last resizing (35GB 45GB) I did not install any new apps or whatever. Also, sum of sizes off all, including hidden & system, root folders and files is ~18GB, yet windows is indicating that all 50GB are used up... Any idea what is going on? EDIT: Great tools everyone! (SourceForge appears to be offline at the moment, I'll check WinDirStat later) Alas, non of them solved my problem just yet... Screenshot from SpaceSniffer: On the right there is some kind of "Unknows Space", any idea what that could be? EDIT2: After those two apps failing to help much I didn't expect it, but WinDirStat actually helped. It showed that those missing 27GB are in my Temp folder (Well, that should have been my first guess anyway). There I found hundreds of ~100MB files, named like HTT????.tmp. After some googling it appears to be a problem with ESET NOD32 antivirus and it's ThreatSense feature. Thank you all for help! :)

• directory services group query changing randomly

  - by yamspog

  I am receiving an unusual behaviour in my asp.net application. I have code that uses Directory Services to find the AD groups for a given, authenticated user. The code goes something like ... string username = "user"; string domain = "LDAP://DC=domain,DC=com"; DirectorySearcher search = new DirectorySearcher(domain); search.Filter = "(SAMAccountName=" + username + ")"; And then I query and get the list of groups for the given user. The problem is that the code was receiving the list of groups as a list of strings. With our latest release of the software, we are starting to receive the list of groups as a byte[]. The system will return string, suddenly return byte[] and then with a reboot it returns string again. Anyone have any ideas? code sample: DirectoryEntry dirEntry = new DirectoryEntry("LDAP://" + ldapSearchBase); DirectorySearcher userSearcher = new DirectorySearcher(dirEntry) { SearchScope = SearchScope.Subtree, CacheResults = false, Filter = ("(" + txtLdapSearchNameFilter.Text + "=" + userName + ")") }; userResult = userSearcher.FindOne(); ResultPropertyValueCollection valCol = userResult.Properties["memberOf"]; foreach (object val in valCol) { if (val is string) { distName = val.ToString(); } else { distName = enc.GetString((Byte[])val); } }

• redirect temporarily STDOUT to another file descriptor, but still to screen

  - by Carlos Campderrós

  I'm making a script that executes some commands inside, and these commands show some output on STDOUT (and STDERR as well, but that's no problem). I need that my script generates a .tar.gz file to STDOUT, so the output of some commands executed in the script also go to STDOUT and this ends with a not valid .tar.gz file in the output. So, in short, it's possible to output the first commands to the screen (as I still want to see the output) but not via STDOUT? Also I would like to keep the STDERR untouched so only error messages appear there. A simple example of what I mean. This would be my script: #!/bin/bash # the output of these commands shouldn't go to STDOUT, but still appear on screen some_cmd foo bar other_cmd baz #the following command creates a tar.gz of the "whatever" folder, #and outputs the result to STDOUT tar zc whatever/ I've tried messing with exec and the file descriptors, but I still can't get it to work: #!/bin/bash # save STDOUT to #3 exec 3>&1 # the output of these commands should go to #3 and screen, but not STDOUT some_cmd foo bar other_cmd baz # restore STDOUT exec 1>&3 # the output of this command should be the only one that goes to STDOUT tar zc whatever/ I guess I'm lacking closing STDOUT after the first exec and reopen it again or something, but I can't find the right way to do it (right now the result is the same as if I didn't add the execs

• unable to destroy windows 2008 r2 failover cluster after SAN rebuild

  - by Zack

  I created a windows 2008 r2 failover cluster for a sql 2008 active/passive cluster. This two node cluster was using a SAN device for a quorum disk resource as well as MSDTC resource. Well....I decided to reconfigure the SAN device, but I didn't destroy the cluster first. Now that the quorum disk and mstdc disk are completely gone, the cluster is obviously not working. But, I can't even destroy the cluster and start again. I've tried from the Windows Clustering tool, as well as the command line. I was able to get the cluster service to start using the "/fixquorum" parameter. After doing this I was able to remove the passive node from the cluster, but it wouldn't let me destroy the cluster because the default resource group and msdtc are still attached as resources. I tried to delete these resources from both the GUI tool, as well as command line. It will either freeze for several minutes and crash the program, or once it even BSOD'd the server. Can someone advise on how to destroy this cluster so I can start over?

• Setup Entourage for Exchange via HTTP communication

  - by Johandk

  Our ISP set up a hosted exchange server for all our mail. I've setup all our Outlook users with no problems. We have two people using Mac OSX Leopard and Entourage. Entourage has the option of adding an Exchange account, but I have no idea how to tell it to connect to exchange via HTTP. Heres an excerpt from the client setup docs the hosting company sent me for Outlook: 1 .Go to control panel 2. Select ‘Mail’ 3. Select ‘Email accounts’ Under the E-mail tab select ‘New’ Select ‘Manually configure server settings......’ - click next Select ‘Microsoft Exchange’ – click next Complete details as below with Microsoft Exchange Server as: [server address] Do not select ‘Check Name’. Instead select ‘More Settings’. Go to the Connection tab, and select the bottom option ‘Connect to Microsoft Exchange using HTTP’. And then select the ‘Exchange Proxy Settings’ button. Enter Proxy server for Exchange Check Only connect to proxy servers that have this principal name in their certificate, Enter msstd:[servername] Proxy Authentication - select Basic Authentication Select OK, and again, so that you return to the main screen. Now select ‘Check Name’. Enter Username and Password: The username should now be the full name and underlined. If so select next, and then finish. Next time you open Outlook, enter username and password Any help GREATLY appreciated.

• Caused by: java.net.SocketException: Software caused connection abort: socket write error

  - by jrishere

  I running JSP on Oracle 11g, Weblogic 10.3.4. I have 2 managed server and a oracle admin server installed. I am encountering an error where intermittently the log file of the 2 managed server and admin server will show java.net.SocketException: Software caused connection abort: socket write error. The application can run for 2 days without showing this error or it can show up a few times in a day. The server load are similar everday. When this error is been encountered, the server will just stop accepting connections and will not be able to access the application. Even if I try to access the application through localhost, I will not be able to access the JSP pages and a 503 http status is shown but then I am able to access the static HTML page. I will not be able to access the Oracle 11g Weblogic admin console page. When I take a look at admin server log, it shows that the managed servers are disconnected from the admin server and vice versa. Magically the application is able to recover by its own and the application is able to access again or I need to restart the server as restarting the service of the application does not work. The FTP connections that the application is connected to are closed as well. I am able to ping to telnet to the server port. The event log doesn't seem to be leaving any information. We did run wireshark to see the packet traffic and it seems that the application port is sending a RST, ACK packet to the load balancer. Any kind help will greatly be appreciated. Should you need more info, feel free to ask me. Thanks in advance.

• Windows 8 - no internet connetction to some hosts while VPN is active

  - by HTD

  I use VPN to access the servers at work. When VPN is used, all network traffic to the Internet passes through my company network. It worked without any problems on Windows 7, now on Windows 8 some sites suddenly became inaccessible. Please note - I don't try to connect them over RDP, they are public Internet addresses, outside company network. They are inaccessible using any protocol. Ping returns "General failure.". I know it could be a misconfiguration on my company's server side, but it's very strange, since the same VPN connection used on Windows 7 works properly. What's wrong? Is it a Windows 8 bug, or is there something I could do on my company servers to make VPN work as expected with Windows 8? My company network works on Windows Server 2008 R2 and uses Microsoft TMG firewall. I couldn't find any rules blocking the traffic to mentioned sites, all network traffic for VPN users are passed through for all IPs and protocols. Any clues? UDPATE: Important - one whole day it worked. I hibernated and restarted the computer, connected and disconnected VPN - nothing could break my connection. Today it broke again, and restarting Windows didn't help. And now the solution: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.1.1 Oh, OK, I know what it did, added my default gateway to routing table. But it still didn't work sometimes. So I removed my main network gateway route with: route delete -p 0.0.0.0 MASK 0.0.0.0 192.168.0.1 And added modified with: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.0.1 And it works. Now. But I don't trust this. I don't know what really happened.

• What does a status of "Backup" mean for Windows 7 local user profiles?

  - by Howiecamp

  Summary: Upon logging on to Windows 7 RTM I get a message that my profile can't be loaded and a temporary user profile is created. I logged off and back on as Administrator. The user profiles dialog shows my user profile with a Type of "Local" and a Status of "Backup" rather than "Local" which it should be. How can I change this to make my user profile accessible? The long story: My PC has a single hard drive partitioned into a C: and a D:. I'd moved my user profile directory (c:\Users) to d:\Users, removed c:\Users and then used mklink.exe to create a directory symbolic link c:\Users -- d:\Users. Worked like a charm since I did it. Today, I make a System Restore Point for drives C: and D:. Next, I dismounted D: and used the Disk Management tool to remove the "D:" drive letter from the D volume. (My plan was to reboot and then redirect the symbolic link.) Upon reboot, I got the user profile error described above. Finally, I restored the System Restore Points that I'd created for both drives and then rebooted again. Same issue.

• can't properly shutdown ubuntu and sound problem on HP mini 311 netbook

  - by Viele

  hi, I recently bought a HP mini 311 netbook. I replaced its harddrive and installed ubuntu 10.04. Since then, I have encountered some very strange problem with its sound and shutdown/reboot. At times, when I start the computer, it will have no sound, on the GUI the sound is at max, but no sound is available. This sometimes also happen after after upgrades, hibernate, and toggling the wireless radio button. Strangely, when the sound is out the device will also refuse to be shutdown. If I shutdown the computer using the GUI, it will simply go back to the log in screen without actually shutting down. If I use "sudo shutdown 0", the computer will hang on the loading screen of the shut down process. I had to force the pc to shutdown by holding the power button down. usually (probably always) after I force a turn-off then start off again. the sound and shutdown become normal. I wonder if anyone have clues regarding to the cause of this problem. This the info about the computer: 1) installed ubuntu 10.04LTS RC, later upgraded to formal released version. 2) cat /proc/asound/version == "Advanced Linux Sound Architecture Driver Version 1.0.21." however, when doing 'alsaconf' the version displayed is 1.0.23 any help is appreciated. Thanks

• Internet slowed down because of SQUID Server setup

  - by Ranjith Kumar

  Recently I have setup a squid server for our office. I have computer (A) with two ethernet cards, one for internet and the second one for local networkIt has Ubuntu server OS with squid-server and dhcp3-server installedI have added few iptable rules to work like a router and redirect all http traffic to 3128 port This link is my reference. Everything worked fine for 2 days. All of a sudden internet speed went down drastically. When I connected the internet cable to my laptop to test the internet speed it was fine. Again when I reconnected it back to computer A everything was normal. This happened 4 times in a week. Could anyone here please help me why the internet speed is going down and it becomes normal when I reconnect the cable. EDIT: Rebooting the system (computer A) didn't make a difference. I have changed iptables so that http traffic doesn't redirect to 3128 port any further, still no change in the internet speed. I think the problem is not with squid but with something else. Here are my iptable rules SQUID_SERVER="10.1.1.1" INTERNET="eth1" LAN_IN="eth0" SQUID_PORT="3128" PROXYSERVERS=(Atlanta Baltimore Boston Chicago Dallas Denver Houston KansasCity LosAngeles Miami NewYork Philadelphia Phoenix SanAntonio SanDiego SanJose Seattle Washington) SERVERLEN=${#PROXYSERVERS[*]} I=0 iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X modprobe ip_conntrack modprobe ip_conntrack_ftp echo 1 /proc/sys/net/ipv4/ip_forward iptables -P INPUT DROP iptables -P OUTPUT ACCEPT iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT iptables -A INPUT -i $INTERNET -m state --state ESTABLISHED,RELATED -j ACCEPT iptables --table nat --append POSTROUTING --out-interface $INTERNET -j MASQUERADE iptables --append FORWARD --in-interface $LAN_IN -j ACCEPT iptables -A INPUT -i $LAN_IN -j ACCEPT iptables -A OUTPUT -o $LAN_IN -j ACCEPT while [ $I -lt $SERVERLEN ]; do iptables -t nat -A PREROUTING -i $LAN_IN -p tcp -d ${PROXYSERVERS[$I]}.wonderproxy.com --dport 80 -j ACCEPT let I++ done iptables -t nat -A PREROUTING -i $LAN_IN -p tcp --dport 80 -j DNAT --to $SQUID_SERVER:$SQUID_PORT iptables -A INPUT --protocol tcp --dport 80 -j ACCEPT iptables -A INPUT --protocol tcp --dport 443 -j ACCEPT iptables -A INPUT --protocol tcp --dport 22 -j ACCEPT iptables -A INPUT -j LOG iptables -A INPUT -j DROP

• Apache rewrite rules and special characters

  - by Massimo

  I have a server where some files have an actual %20 in their name (they are generated by an automated tool which handles spaces this way, and I can't do anything about this); this is not a space: it's "%" followed by "2" followed by "0". On this server, there is an Apache web server, and there are some web pages which links to those files, using their name in URLs like http://servername/file%20with%20a%20name%20like%20this.html; those pages are also generated by the same tool, so I (again!) can't do anything about that. A full search-and-replace on all files, pages and URLs is out of question here. The problem: when Apache gets called with an URL like the one above, it (correctly) translates the "%20"s into spaces, and then of course it can't find the files, because they don't have actuale spaces in their names. How can I solve this? I discovered than by using an URL like http://servername/file%2520name.html it works nicely, because then Apache translates "%25" into a "%" sign, and thus the correct filename gets built. I tried using an Apache rewrite rule, and I can succesfully replace spaces with hypens with a syntax like this: RewriteRule (.*)\ (.*) $1-$2 The problem: when I try to replace them with a "%2520" sequence, this just doesn't happen. If I use RewriteRule (.*)\ (.*) $1%2520$2 then the resulting URL is http://servername/file520name.html; I've tried "%25" too, but then I only get a "5"; it just looks like the initial "%2" gets somewhat discarded. The questions: How can I build such a regexp to replace spaces with "%2520"? Is this the only way I can deal with this issue (other than a full search-and-replace which, as I said, can't be done), or do you have any better idea?

• Liferay - Verify each node in a cluster

  - by Schrute

  In this example, I have two clustered instances of Liferay using bundled Tomcat running, using cluster link and shared documents. Let's say the name of the public community is fubar and friendy URL used is fubar.lipsum.com. Let's say the ports listening on each server is 8080. If I go to both server1:8080 or server2:8080 I will get the default page for Liferay. How can I test fubar.lipsum.com on each node by using the backend server, so I can verify each server? If I test it, it just goes to the load balancer, I wish there was a way to append to the backend connection to bring it up. I can add the friendly URL to my local machines hosts file and this seems to kinda work, but then once something is called in the application, it tries to go out again from the backend server and then uses SSL and then we have problems. I think I may be able to do port forwarding, but this seems like a basic thing we should be able to do and what I've found so far in the admin docs has not helped. Using the option to print the server name in the page details isn't an option either.

• Uninstall IIS on Windows 7

  - by CJM

  I've just rebuilt my development machine and installed IIS. I then installed the Web Deployment tool and used this to restore my previously-backed-up websites to the clean machine. Unfortunately the restoration didn't work correctly/fully. I couldn't easily correct the problem, so I decided to uninstall/reinstall IIS and recreate the sites manually. I uninstalled IIS and rebooted, but there was still plenty of stuff left around such as various files in /windows/system32/inetsrv/ which I tried to delete manually (with limited success!). I rebooted again and tried to reinstall IIS - it reported an error (no meaningful message) and requested another reboot. The event log includes the following errors: The World Wide Web Publishing Service (WWW Service) did not register the URL prefix http://*:80/gallery for site 1. The site has been disabled. and Unable to bind to the underlying transport for [::]:80. The IP Listen-Only list may contain a reference to an interface which may not exist on this machine. I'd like to avoid another rebuild. Can I completely remove IIS, such that I can reinstall it from scratch? Or can I 'fix' the current setup so that IIS will reinstall over what is already there?

• Formatting a a memory stick with two partitions?

  - by Marius

  I have a 16GB memorystick which used to have a Linux partition. It therefore has two partitions; 2GB FAT32 and 14GB linux boot drive. The linux part stopped working, so I decided to reinstall it. But windows can't see that partition. I tried formatting the whole disk, but I can only format one partition (the FAT32). There seems to be no way to combine the two partitions into one big one, and there seems to be no way for windows to partition the large part of the memorystick to but Linux on it. In the windows partition manager, windows sees the large unused partition, and it let me delete it. But once I have deleted it, I'm not allowed to format it. Also I cannot delete or resize the small partition. So, to summarize: I have a memorystick with two partitons. Windows only sees one of them, and won't let me use the other one. I would like to combine the two partitions so I can install Linux on the memory stick again.

• KVM guest VLAN aware problems

  - by baraka

  Hi, We are using Centos 5.5. as KVM host. It has two nics. One for management and the other one for services. As we have services in multiple vlans this nic is configured as a 802.1Q trunk. Any VM must be able to have access to any vlan, so host trunk interface is bridged to its tap interface and vlan is configured inside VM. Everything works fine while there is not heavy traffic. I can not find any log on guest or host, but, after some certain sustained big file transfer (about 6Gb) bridging stop working. Other guest on the same host continue working without problems. tcpdump on bridge interface is Ok, but on guest tap inferface I can see only outgoing traffic. Restarting bridge or rejoining tap interface doesn't provide any clue. Rebooting guest turns on bridge again. Bridge configuration is minimal: just addbr and addif (no stp). Any idea welcome!

• Easy GUI way to auto scale EC2 and RDS: aws console, scalr, ylastic...?

  - by Zillo

  I am managing all my instances with the AWS Management Console (the GUI web console) but now I want to use Auto Scale and it seems that this can not be done with that console. Yes, there is CloudWatch but I can only create alarms (e-mail notifications), it seems that CouldWatch needs you to add the auto scale policy in some other place (by command line console?). I would like to use some easy GUI interface. Ylastic and Scalr seems to be a good option. Which one do you think is better? Regarding Scalr, is there any difference between the open source software Scalr and the service Scalr.net? I mean, is the GUI interface the same? I like the idea of the Scalr because I do not need to give my Secret Access Key to a third party (like in Ylastic or in Scalr.net) One question about the Scalr software, it has to be installed in the instances or it must be installed in another machine? Do I need to setup again all my security permissions, AMIs, snapshots, etc. or I can use AWS Management Console for everything and Scalr just to auto scale.

• Encryption setup for Linux NAS?

  - by Daniel

  There's a bazillion hard disk encryption HOWTOs, but somehow I can't find one that actually does what I want. Which is: I have a home NAS running Ubuntu, which is being accessed by a Linux and a Win XP client. (Hopefully MacOS X soon...) I want to setup encryption for home dirs on the NAS so that: It does not interfere with the boot process (since the NAS it tucked away in a cupboard), the home dirs should be accessible as a regular file system on the client(s) (e.g. via SMB), it is easy to use by 'normal' people, (so it does not require SSH-ing to the NAS, mount the encrypted partition on command line, then connecting via SMB, and finally umount the partition after being done. I can't explain that to my mom, or in fact to anyone.) does not store the encryption key the NAS itself, encrypts file meta-data and content (i.e. safe against the 'RIAA' attack, where an intruder should not be able to identify which songs are in your MP3 collection). What I hoped to do was use Samba + PAM. The idea was that on connecting to the SMB server, I'd have to enter the password on the client, which sends it to the server for authentication, which would use the password to mount the encrpytion partition, and would unmount it again when the session was closed. Turns out that doesn't really work, because SMB does not transmit the password in the plain and hence I can't configure PAM to use the incoming password to mount the encrypted patition. So... anything I'm overlooking? Is there any way in which I can use the password entered on the client (e.g. on SMB connect) to initiate mounting the encrypted dir on the server?

• Resize a RAID 1 volume on OSX Snow Leopard - how? (Note: software raid)

  I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OSX 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable...), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

• How to re-join an AD2003 domain with Samba after deleting the machine account?

  - by Guss

  During some troubleshooting I deleted the machine account for a Linux server running samba from our AD 2003 domain. We are using Kerberos for authentication, and after I deleted the machine account I tried to join the domain again using net ads join -U Administrator But I keep getting Kerberos errors like these: [2009/08/18 16:14:36, 0] libads/kerberos.c:ads_kinit_password(228) kerberos_kinit_password [email protected] failed: Client not found in Kerberos database Failed to join domain: Improperly formed account name It appears as if samba remembers that it once had an account with the AD and keeps trying to reconnect to it, but I want to create a new account from scratch. I tried to delete all the .tdb files I could find as well as everything under /var/cache/samba but to no avail - it still behaves the same. I also tried to create the machine account on the AD side, but then I get a similar error when I try to join, about failure to authenticate with the machine account - it looks like samba tries the previous machine account password and I don't know how to reset it, or even if I could figure out what samba uses - how to set it in the AD. Any help would be greatly appreciated, as at this point the only thing I can think about is to reformat and reinstall the machine, and I would really REALLY love to not do that. Thanks in advance.

• Android failure to boot on LG [migrated]

  - by Ukavi

  I need to recover data from my AT&T LG Thrill Android Phone Background: My AT&T LG Thrill phone's battery died a couple of days ago because I forgot to charge it. When I charged the phone and tried to turn it on, it showed the LG logo followed by the dropping balls and the AT&T "Rethink Possible" screen. I then get a mesage that the Application Google Services Framework has crashed and the phone goes into a loop with the dropping balls showing again followed by "Rethink Possible" screen. This sequence repeats itself over and over and the phone does not get out of this loop. I have been able to go into the recovery screen (both Safe Mode and the Android Recovery Service) and have cleared cache, etc. However, I DO NOT want to wipe user data and restore to factory settings as this will wipe all of my data (pictures, application data, etc). Solution Needed: I need a suggestion to a way of accessing my data so that I can back it up onto an SD card/computer. I DO NOT want to root the phone as this may void the warranty. What I'm looking for is a way of perhaps putting the original flash image on the micro SD card and then have the phone read that image. Or some other similar solution that will get the phone out of this loop and allow me to get to the data.
