• Strange File-Server I/O Spikes - What Is Causing This?

  - by CruftRemover

  I am currently having a problem with a small Linux server that is providing file-sharing services to four Windows 7 32-bit clients. The server is an AMD PhenomX3 with two Western Digital 10EADS (1TB) drives, attached to a Gigabyte GA-MA770T-UD3 mainboard and running Ubuntu Server 10.04.1 LTS. The client machines are taking an extremely long time to access/transfer data on the file server. Applications often become non-responsive while trying to open files located remotely, or one program attempting to open a file but having to wait will prevent other software from accessing network resources at all. Other examples include one image taking 20 seconds or more to open, and in one instance a user waited 110 seconds for Microsoft Word 2007 to save a document. I had initially thought the problem was network-related, but this appears not to be the case. All cables and switches have been tested (one cable was replaced) for verification. This was additionally confirmed when closing down all client machines and rebooting the server resulted in the hard-drive light staying on solid during the startup process. For the first 15 minutes during boot, logon and after logging on (with no client machines attached), the system displayed a load average of 4 or higher. Symptoms included waiting several minutes for the logon prompt to appear, and then several minutes for the password prompt to appear after typing in a user name. After logon, it also took upwards of 45 seconds for the 'smartctl' man page to appear after the command 'man smartctl' was issued. After 15 minutes of this behaviour, the load average dropped to around 0.02 and the machine behaved normally. I have also considered that the problem is hard-drive-related, however diagnostic programs reveal no drive problems. Western Digital DLG, Spinrite and SMARTUDM show no abnormal characteristics - the drives are in perfect health as far as the hardware is concerned. I have thus far been completely unable to track down the cause of this problem, so any help is greatly appreciated. Requested Information: Output of 'free' hxxp://pastebin.com/mfsJS8HS (stupid spam filter) The command 'hdparm -d /dev/sda1' reports: HDIO_GET_DMA failed: Inappropriate ioctl for device (the BIOS is set to AHCI - I probably should have mentioned that).

• Is it better to always copy and delete, rather than move?

  - by nbolton

  Generally speaking, I find myself panicking when I realise that if I cancel a file move, it could cause the target or source to be incomplete. This question applies to Windows and Unix-based platforms. I can never remember exactly how the move command works in either case. For example, if you're moving a directory; does it copy the entire directory, then delete it after, or does it copy then delete each file individually? I always realise after typing something like, mv verybigdir dest that I really should have typed cp -R verybigdir dest && rm verybigdir (where the && operator only moves to the next command if the first was successful) -- or is this pointless? What happens exactly when I press Ctrl+C half way through a move? Likewise, what exactly happens on Windows when I press the cancel button? I can't count the number of times I've moved something (the last time was when using svn) and had two directories, with split contents. I guess the answer is difficult, because not all applications move groups of files in the same way.

• Is there a way to do a sector level copy/clone from one hard drive to another?

  - by irrational John

  Without going into distracting details, I'm attempting to duplicate the contents of the 500GB drive in my MacBook to another 500GB drive. But this is turning out to be an unexpected hassle because the drive contains both the OS X partition and an NTFS partition with Win 7 via Apple's Boot Camp. With the exception of Clonezilla, the tools I have looked at so far all have some limitation. The Mac tools don't want to deal with the NTFS partition. The Windows tools are totally clueless about either the HFS+ partition and/or the hybrid MBR/GPT Boot Camp partitioning. Clonezilla looked like it would do what I want but apparently I can't figure out how to use it. After doing what I thought was a sector to sector copy I found that only the NTFS partition had been migrated. The others were apparently empty. (And frankly, I'm not positive Clonezilla migrated the partition table correctly either). Note: It takes over 2 hours using SATA to read/write all sectors with these drives. So I'm not up for using trial & error to narrow in on the right combination of Clonezilla options to use. I'm beginning to think that maybe the answer is to boot Linux (probably Ubuntu) and then use some ancient BSD command. Trouble is I don't know what command (or parameters to use) in order to do a sector level copy from one drive to another. As far as I know the drives have the same number of sectors so this should be trivial. Sigh.

• Access to CD/DVD Drive is Denied through Windows 7 Explorer (Permission Problem)

  - by Synetech inc.

  A while ago I started having trouble with my optical drives. Both of them keep showing up in Explorer as CD/DVD drives on boot, but as soon as I put a disc in either one, it suddenly turns into a hard-drive—“local disk” is displayed in the Type column, though the File System column remains UDF/CDFS. (I though that maybe it was a permission issue on the registry key in HKLM\System\CurrentControlSet..., but I’m not so certain because of the next test.) When I try to open a disc (of any type), I get an access denied error message. If I open an elevated command-prompt, I am able to access the files. Also, if I kill Explorer and run it from an elevated command-prompt (thus giving Explorer elevated permissions), then I can access the files from Explorer. I’ve tried uninstalling and reinstalling the devices without success. The security dialog indicates that there are none set for the drives (no owner and no permissions). I tried setting the owner, but am only able to do so if there is a disc in it (it complains if it is empty), but the settings do not stick (if I immediately open the security dialog after setting it, it is empty again). I tried setting permissions, but that gives an error. I’ve included a screencap-flowchart of the security dialog of one of the drives below. (Yes, I made sure that there are no upper- or lower-filters, and yes, I ran sfc. I also made sure that in the policy editor, “devices: restrict CD-ROM...” is not set.) Does anyone know what the owner and permissions are supposed to be for optical drives and how to reset them?

• How do I get rid of these "There is a problem with your tablet driver" messages?

  - by Adam Rosenfield

  Every time I run certain applications (including but not limited to GIMP, Microsoft Visual Studio, and 3DS Max), I get the following message box: There is a problem with your tablet driver. Please reboot your system. If the problem persists reinstall or update the driver. Obviously I've tried rebooting and that hasn't fixed anything. Secondly, I'm not running a tablet PC. This is just Windows XP SP3 running on a Dell Precision PWS490 desktop workstation. How do I get rid of these error messages? The applications still load normally after dismissing them, but they're rather annoying. Using Process Explorer, I got the call stack from the message box. It's coming from wintab32.dll. Here's the call stack when running GIMP (irrelevant frames omitted): ... 8 USER32.dll!MessageBoxA+0x45 9 wintab32.dll!WTMgrPacketHookExA+0x44a 10 libgdk-win32-2.0-0.dll!gdk_display_list_devices+0x37 ... So, does anyone know how I can get an updated version of wintab32.dll or have any other ideas? I've been keeping my system up to date with Windows Updates. The timestamp on wintab32.dll is 2007-03-30 17:38, and its MD5 sum is ffdc332007c9dc6dd346c8ac2b09a015.

• How to Set Up an SMTP Submission Server on Linux

  - by Kevin Cox

  I was trying to set up a mail server with no luck. I want it to accept mail from authenticated users only and deliver them. I want the users to be able to connect over the internet. Ideally the mail server wouldn't accept any incoming mail. Essentially I want it to accept messages on a receiving port and transfer them to the intended recipient out port 25. If anyone has some good links and guides that would be awesome. I am quite familiar with linux but have never played around with MTA's and am currently running debian 6. More Specific Problem! Sorry, that was general and postfix is complex. I am having trouble enabling the submission port with encryption and authentication. What Works: Sending mail from the local machine. (sendmail [email protected]). Ports are open. (25 and 587) Connecting to 587 appears to work, I get a "need to starttls" warning and starttls appears to work. But when I try to connect with the next command I get the error below. # openssl s_client -connect localhost:587 -starttls smtp CONNECTED(00000003) depth=0 /CN=localhost.localdomain verify error:num=18:self signed certificate verify return:1 depth=0 /CN=localhost.localdomain verify return:1 --- Certificate chain 0 s:/CN=localhost.localdomain i:/CN=localhost.localdomain --- Server certificate -----BEGIN CERTIFICATE----- MIICvDCCAaQCCQCYHnCzLRUoMTANBgkqhkiG9w0BAQUFADAgMR4wHAYDVQQDExVs b2NhbGhvc3QubG9jYWxkb21haW4wHhcNMTIwMjE3MTMxOTA1WhcNMjIwMjE0MTMx OTA1WjAgMR4wHAYDVQQDExVsb2NhbGhvc3QubG9jYWxkb21haW4wggEiMA0GCSqG SIb3DQEBAQUAA4IBDwAwggEKAoIBAQDEFA/S6VhJihP6OGYrhEtL+SchWxPZGbgb VkgNJ6xK2dhR7hZXKcDtNddL3uf1YYWF76efS5oJPPjLb33NbHBb9imuD8PoynXN isz1oQEbzPE/07VC4srbsNIN92lldbRruDfjDrAbC/H+FBSUA2ImHvzc3xhIjdsb AbHasG1XBm8SkYULVedaD7I7YbnloCx0sTQgCM0Vjx29TXxPrpkcl6usjcQfZHqY ozg8X48Xm7F9CDip35Q+WwfZ6AcEkq9rJUOoZWrLWVcKusuYPCtUb6MdsZEH13IQ rA0+x8fUI3S0fW5xWWG0b4c5IxuM+eXz05DvB7mLyd+2+RwDAx2LAgMBAAEwDQYJ KoZIhvcNAQEFBQADggEBAAj1ib4lX28FhYdWv/RsHoGGFqf933SDipffBPM6Wlr0 jUn7wler7ilP65WVlTxDW+8PhdBmOrLUr0DO470AAS5uUOjdsPgGO+7VE/4/BN+/ naXVDzIcwyaiLbODIdG2s363V7gzibIuKUqOJ7oRLkwtxubt4D0CQN/7GNFY8cL2 in6FrYGDMNY+ve1tqPkukqQnes3DCeEo0+2KMGuwaJRQK3Es9WHotyrjrecPY170 dhDiLz4XaHU7xZwArAhMq/fay87liHvXR860tWq30oSb5DHQf4EloCQK4eJZQtFT B3xUDu7eFuCeXxjm4294YIPoWl5pbrP9vzLYAH+8ufE= -----END CERTIFICATE----- subject=/CN=localhost.localdomain issuer=/CN=localhost.localdomain --- No client certificate CA names sent --- SSL handshake has read 1605 bytes and written 354 bytes --- New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Session-ID: E07926641A5EF22B15EB1D0E03FFF75588AB6464702CF4DC2166FFDAC1CA73E2 Session-ID-ctx: Master-Key: 454E8D5D40380DB3A73336775D6911B3DA289E4A1C9587DDC168EC09C2C3457CB30321E44CAD6AE65A66BAE9F33959A9 Key-Arg : None Start Time: 1349059796 Timeout : 300 (sec) Verify return code: 18 (self signed certificate) --- 250 DSN read:errno=0 If I try to connect from evolution I get the following error: The reported error was "HELO command failed: TCP connection reset by peer".

• How to install Red Hat Enterprise Linux on Apple Macbook Pro MacBookPro4,1

  - by Todd V. Rovito

  I have a one year old Mac Book Pro that I am trying to get RHEL 5.4 installed on via bootcamp. No matter what I do I can't get the installer to boot. I have tried multiple DVD's and even verified the install works on a new Mac Book Pro. Most of the time the installer simply locks up. I usually use Linux text with all-generic-ide on the boot line. I removed the ide parameter and I just used linux text. The results I get are that a bunch of kernel messages appear then the background turns blue and a thin text box pops up saying its loading ata..... something it disappears too fast for me to read. Then the machine freezes. I pressed the alt function keys to see if I could look at the system log, here is what it says: Alt-f3 says "trying to mount CD device hda" Alt-f4 says status error: hda: lastFailedSense Hda: Failed opcode was: unknown Hda: Lost interrupt Hda: Drive not ready for command Ide-cd: command 0x3 timed out Above this junk it looks like it found the partition because it knew it was 20 GB and listed as /dev/sda3. I think it has something to do with the CD drive, is that possible? Thanks again for the support. PS I posted in the apple support forums ( Apple.com Support Discussions Boot Camp Installation and Storage) and didn't get an answer.

• backup an existing linux server to a virtualbox virtual machine

  - by user146526

  I have some servers and VPSs to many companies across the world. I want to back them up locally. I have some backup solutions enabled to remote hosts, but I want to have a local backup on a computer at home. What I am thinking is: 1) Create a virtualbox virtual machine, install the same version linux as the server. 2) Use rsync to backup the server to the local virtualbox machine. (something like rsync -av --delete --progress --exclude '/dev/' --exclude '/proc/' root@server_ip:// / ) 3) Repeat the command every few days update files. 4) In case of a hard disk failure, or any other bad event, reverse the rsync command and get the files back and continue my bussiness. I tried it with 2 openvz VPS, the one was a backup of the other. I also tried to transfer normal linux server host to openvz machine and it worked great. That way looks pretty clean and easy to me, this is the kind of solution I am looking for. However I need to be sure that this will work if I am going to do it. The question is, will that work ok ? Does anyone see any problem with that ? Do you have any other suggestions ? Thanks

• Exchange 2003 Internet Mail Size Limits

  - by scampbell

  I have unsuccessfully tried to increase per user incoming mail size settings by editing their user account settings on our Exchange server, but large incoming mail from external domains is still blocked using the default global settings. After reading here: http://support.microsoft.com/default.aspx?scid=kb;en-us;322679 I see that All Internet e-mail messages use the global setting for limits on sending and on receiving. The message categorizer evaluates the sender's sending limit and the recipient's receiving limit. In example 2 earlier, a user with a user mailbox limit of 3 MB could receive messages from another user with a 3-MB sending limit. Because Internet users use the global setting, they can send only a 2-MB message. Which to me is madness! Surely if I want to allow a user to receive mail up to a certain size then I should be able to set it as such? Is there a specific way of getting round this? Would setting the global defaults high and setting a lower, say 10MB, limit on the SMTP connector do the trick? Thanks.

• Compatibility of Fedora install on a Hybrid drive

  - by kjh

  I recently bought un ultrabook with a 500gb/32gb sdd hdd hybrid drive, and I'm having trouble replacing windows on it with fedora seventeen. it errors out saying there was an unhandled exception. Is linux compatible with hybrid drives? or can the operating system on a hybrid drive not be replaced? Edit: here are the steps I select special storage devices because it ignores my hard drives otherwise at this point i get the message: "Disk contains bios raid meta data, disk sda will be ignored" I can pick a hostname, select my timezone and set a password at the install type screen, no matter what I select (use all free space, replace linux systems, create custom partition etc..) once I click next, it says "an unhandled exception" has occured. and I can no longer proceed with installation. Here is the error message: anaconda 17.29 exception report Traceback (most recent call first); File "/usr/lib64/python2.7/size-packages/pyanaconda/bootloader.py"; line 183 self.stage1_drive=self_drives[0] File "/usr/lib64/python2.7/site-packages/pyanaconda/rw/cleardisks_gui.ph"; line... and tons of more lines like that

• Formatting pwd/ls for use with scp

  - by eumiro

  I have two terminal windows with bash. One is local on the client computer, another one has an SSH-session on the server. On the server, I am in a directory and seeing a file I would like to copy to my client using scp from the client. On the server I see: user@server:/path$ ls filename filename I can now type scp in the client shell, select and copy the user@server:/path from the server shell and paste to the client shell, then type slash and copy and paste the filename and append a dot to get: user@client:~$ scp user@server:/path/filename . to scp a file from the server to the client. Now I am searching for a command on the server, that would work like this: user@server:/path$ special_ls filename user@server:/path/filename which would give me the complete scp-ready string to copy&paste to the client shell. Something in the form echo $USER@$HOSTNAME:${pwd}/$filename working with relative/absolute paths. Is there any such command/switch combination or do I have to hack it myself? Thank you very much.

• Apps won't start after vanilla reboot

  - by Daniel R Hicks

  I had Adobe and Norton nagging me to reboot, so I did that -- clicked Reboot from the Start button. Everything seemed pretty normal as it shut down and came back up, but once up a bunch of apps won't start. The first one I noticed was Firefox. It would flash the disk light normally, but never appear on the screen. Then I tried to bring up an OpenOffice Calc window and same thing. I tried to bring up MS Word, and the splash screen appeared, but never the main screen, and the splash screen just sat there, with a swirly over it. But I tried Solitaire, Notepad++, Paint, and several others, and they popped up just fine. And I'm typing this from IE 8, which, if anything, came up faster than usual. When I try to open up "Network and Sharing Center" the window appears, but nothing appears in it, and eventually it's tagged "not responding". When I kill that window I get (after a delay) "Windows Explorer is not responding", and when I say "OK" the screen resets. I tried rebooting again, and no joy -- same as before. Have done nothing particularly strange on this box, and it's not generally at significant risk for malware. I haven't installed anything new other than the afore-mentioned updates. One other thing: Several minutes after rebooting I get the message "Error: Unable to start Bluetooth Stack Service." The Bluetooth radio is turned on, and I rarely have anything Bluetooth attached, and I don't recall that I've ever seen this message before. Added: Looking at Event Viewer, I'm getting a lot of "The description for Event ID 1 from source xxx cannot be found." Is there any significance to this? Added: I'm looking at restoring from backup, but the procedure is, at best, unclear. Is it sufficient to restore from "Backup and Restore Center", or must I restore from the restore DVD first?

• INACCESSIBLE_BOOT_DEVICE after installing Linux on same drive

  - by kdgregory

  History: My PC was configured with two drives: an 80G on IDE 0 Primary that was running Win2K, and a 320G on IDE 0 Secondary that was running Linux (Ubuntu). I decided to pull the 80Gb drive out of the system, so dd'd the entire 80 G drive (/dev/sda) onto the 320 (/dev/sdb) -- this included the MBR and partition table. Then I pulled the drive, plugged the 320 into IDE 0 Primary, and rebooted. The Windows partition worked at this point. Then I installed Ubuntu into the remaining space on the 320. It works. However, when I try to boot into Windows, I get a BSOD with the following message: *** STOP: 0x0000007B (0x89055030,0xC000014F,0x00000000,0x00000000) INACCESSILE_BOOT_DEVICE Before the BSOD I see the Win2K splash screen, and it claims to be "starting windows" for a couple of seconds -- so it appears that the first stage boot loader is working as expected. Ditto when I try booting in Safe Mode. After reading the Microsoft KB article, I booted into the recovery console and tried running chkdsk /r. It refused to run, claiming that the drive was corrupted (sorry, didn't write down the exact error message). However, I can mount the drive from Linux, and access all files. And for what it's worth, I can scan the drive using the Linux "Disk Utility" (this is Ubuntu, the menus don't show real program names), it claims the drive to be clean. The KB article mentioned that boot.ini could be the problem, so here it is: timeout=10 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows 2000 Professional" /fastdetect Any pointers on what to do next?

• Safe use of Update-FormatData?

  - by Steve B

  In a custom PowerShell module, I have at the top of my module definition this code: Update-FormatData -AppendPath (Join-Path $psscriptroot "*.ps1xml") This is working fine as all .ps1xml files are loaded. However, the module is sometimes loaded using Import-Module MyModule -Force (actually, this is in the install script of the module). In this case, the call to Update-FormatData fails with this error : Update-FormatData : There were errors in loading the format data file: Microsoft.PowerShell, c:\pathto\myfile.Types.ext.ps1xml : File skipped because it was already present from "Microsoft.PowerShell". At line:1 char:18 + Update-FormatData <<<< -AppendPath "c:\pathto\myfile.Types.ext.ps1xml" + CategoryInfo : InvalidOperation: (:) [Update-FormatData], RuntimeException + FullyQualifiedErrorId : FormatXmlUpateException,Microsoft.PowerShell.Commands.UpdateFormatDataCommand Is there a way to safely call this command? I know I can call Update-FormatData with no parameters, and it will update any known .ps1xml file, but this would work only if the file has already been loaded. Can I list somewhere the loaded format data files? Here is a bit of background: I'm building a custom module that is installed using a script. The install script looks like : [CmdletBinding(SupportsShouldProcess=$true,ConfirmImpact="High")] param() process { $target = Join-Path $PSHOME "Modules\MyModule" if ($pscmdlet.ShouldProcess("$target","Deploying MyModule module")) { if(!(Test-Path $target)) { new-Item -ItemType Directory -Path $target | Out-Null } get-ChildItem -Path (Split-Path ((Get-Variable MyInvocation -Scope 0).Value).MyCommand.Path) | copy-Item -Destination $target -Force Write-Host -ForegroundColorWhite @" The module has been installed. You can import it using : Import-Module MyModule Or you can add it in your profile ($profile) "@ Write-Warning "To refresh any open PowerShell session, you should run ""Import-Module MyModule -Force"" to reload the module" Import-Module MyModule -Force Write-Warning "This session has been refreshed." } } MyModule defines, as first statement, this line : Update-FormatData -AppendPath (Join-Path $psscriptroot "*.ps1xml") As I updated my $profile to always load this module, the Update-Path command has been called when I run the install script. In the install script, I force import the module, which be fire again the module, and then, the Update-Path call

• What kind of server configuration is best for a chatting app? [closed]

  - by mohabitar

  I'm just now starting to go deeper into the world of cloud hosting and databases, and am getting overwhelmed by how deep this information goes. It's all a little too much to consume in a short amount of time. I get a lot of pricing information, but I'm unable to determine what that means to me. I'm making what you might compare to an email app. Users can send messages to one another. I just don't understand, out of the several options, what would be ideal for an app like this, where users would be constantly sending and receiving text data. With Amazon DynamoDB, I have to specify a pre-defined throughput with number of reads and writes per second. Sure I can just type 50, but I'm not exactly sure what 50 writes per second represents. I'm trying to determine what would be the most cost efficient solution, and I want to know what a throughput of 50 reads/writes/second compares to. Is that a high number? What is a good throughput number for a message sending app with say 50,000 daily users? I'm just providing specific numbers so I can understand what these throughput numbers represent. 100 transactions/second to me seems like a small number since I'm not familiar with this stuff, so I'm just looking to bring everything in context. What would 100 read/write/second be useful for? Are there any average example values available? And I'm not sure what each service is good for. For a message sending app, is there any reason I'd want to choose say Amazon DynamoDB over Google App Engine? Any insight would be greatly appreciated.

• Windows 7 BSOD on boot after windows update

  - by Razor Storm

  After Windows updates today, I restarted my desktop (for the first time in a couple weeks), and on boot up ran into a BSOD: STOP: 0x0000007E (0xFFFFFFFFC0000005, 0xFFFFF8000355AB5A, 0xFFFFF880031CB3A8, 0xFFFFF880031CAC10) I tried system restore, but there was only 1 restore point which was from all the way back in January. I tried it anyway but after 10 minutes of running it said system restore could not be completed. Additional info: I checked my BIOS and it is detecting my rams. CPU is Intel Sandy Bridge i5-2500k overclocked to 4.3GHz. I reclocked it back to stock speeds (3.3 GHz) in case it was causing the issue (I highly doubt that it is). But the problem persists. Running Windows 7. 12 GB of RAM at 1333 MHz OS on 64gb SSD. What is causing this? How should I fix it? Also, if it is caused by windows update, is there a way to undo the update with command prompt? I tried safemode, and the blue screen comes up as well, but I am able to access command prompt.

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();

• How to resume XMPP groupchat window in Irssi (using bitlbee)?

  - by mcnesium

  I use Bitlbee to chat in XMPP-networks within my IRC-client Irssi. This works great so far, and recently I started using XMPP Multi User Chats as an alternative to IRC-channels. I set up a channel using chat add <account> <[email protected]> in the &bitlbee control window, set chan <room> set autojoin true and entered /join #room in the &bitlbee window to join that groupchat. It then appears as a unique Irssi window in the status bar. This seems to work ok too, but with one exception: Since I idle in the channels 24/7 my irssi has to cope with the every-night-24h-DSL-disconnection by the ISP. After it automatically reconnects, it does kind of rejoin that XMPP-groupchat, but the traffic of the groupchat does not go back to the unique irssi window, but keeps flooding &bitlbee with messages from root telling me about a Groupchat Message from unknown JID <jid>: <message> - which is the traffic of the groupchat. The unique groupchat window is gone after the reconnect, and I will again have to go /join #room in &bitlbee to get it back. Even worse, the window number is unused before I rejoin the groupchat, and if I get a query from any network, the window nests in that unused window spot, so I will first have to remove that query from the spot, and then move the rejoined groupchat to that window number. I want my groupchat window to resume after the reconnect just like every other IRC channel too. How can I get this done? Any ideas?

• 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?

• troubleshooting really slow login on a (linux) machine

  - by Peeter Joot

  Within the last couple of weeks, any attempt to login to a specific linux server has gotten really slow. Once I've logged in, things appear to run without significant delay, but some other login like activities (like starting a new screen session) are slow. The machine's been rebooted a couple of times recently and that hasn't helped. , and it doesn't appear to be $PATH search (where $PATH can sometimes include bad NFS mounts), which I've seen historically in our environment. I've also tried completely removing my .profile/.bash*/... type of init files to rule out anything bad there. I also see slow login for at least one other userid on the system. One thing I've noticed is the following message when trying to exit from a screen terminal: Utmp slot not found -> not removed and am wondering if this is related (having a vague recollection that Utmp has something to do with login). Any idea what that message means, or how to fix it, and if it would be related? Failing that, what sort of problem determination tools are available to investigate what is slowing down this login process?

• S3sync not working

  - by user57833

  Hello, I managed to get s3sync to upload my test folder to Amazon S3 and can see it in the MWS Managment Console. Downloading the data back to a test folder results in the following error message: root@mybucketname:/var/s3sync# ./week_download.sh s3Prefix backups/weekly localPrefix /var/s3sync/testdown/weekly s3TreeRecurse mybucketname backups/weekly Creating new connection Trying command list_bucket mybucketname prefix backups/weekly max-keys 200 delimiter / with 100 retries le ft Response code: 200 prefix found: / s3TreeRecurse mybucketname backups/weekly / Trying command list_bucket mybucketname prefix backups/weekly/ max-keys 200 delimiter / with 100 retries l eft Response code: 200 S3 item backups/weekly/ s3 node object init.

Does the download script need to download to the source of Amazon S3 i.e testup folder? Was hoping on the instance of a complete failure and the original folders won't exist that it would just download everything from me. Note: changed my bucket names to "mybucketname" so that it is not public!

• After RAID failure SBS 2008 issues logging in and Exchange store does not mount

  - by Josh R

  today has been one of those days. Yesterday a hard drive in our Dell Poweredge 2900 server failed and the RAID array didn't degrade gracefully, so I called Dell (Server still under warranty) and got an engineer to work though the RAID issues with me. He was a nice guy but didn't do too much. We tried to put the RAID in a state where it was bootable and even though we only lost one disk there are still issues with the server. Once we got the server to boot there was an error message saying that the logonui.exe was corrupted and we needed to run chkdsk. I clicked through the error messages and the login screen never came up. So I power cycled the server and it chkdsk automatically but the login screen didn't appear. I tried safe mode, no difference there either. So the issues I am currently having are: 1) The server boots up, the loading windows screen comes up then it dumps me into a black screen where I can only see my mouse cursor. Ctrl+Esc doesn't work Ctrl+Alt+Del doesn't work 2) Some of the services come up: DHCP, DNS, DFS, and Print come up 3) The exchange information store and transport service don't start - I tried using mmc to connect to services.msc on the computer and start them but they throw an error message of "Can't start because group or dependency failed" Has anyone had a problem like this? Can anyone offer some guidance? Thanks a bunch!
