• extreme slowness with a remote database in Drupal

  - by ceejayoz

  We're attempting to scale our Drupal installations up and have decided on some dedicated MySQL boxes. Unfortunately, we're running into extreme slowness when we attempt to use the remote DB - page load times go from ~200 milliseconds to 5-10 seconds. Latency between the servers is minimal - a tenth or two of a millisecond. PING 10.37.66.175 (10.37.66.175) 56(84) bytes of data. 64 bytes from 10.37.66.175: icmp_seq=1 ttl=64 time=0.145 ms 64 bytes from 10.37.66.175: icmp_seq=2 ttl=64 time=0.157 ms 64 bytes from 10.37.66.175: icmp_seq=3 ttl=64 time=0.157 ms 64 bytes from 10.37.66.175: icmp_seq=4 ttl=64 time=0.144 ms 64 bytes from 10.37.66.175: icmp_seq=5 ttl=64 time=0.121 ms 64 bytes from 10.37.66.175: icmp_seq=6 ttl=64 time=0.122 ms 64 bytes from 10.37.66.175: icmp_seq=7 ttl=64 time=0.163 ms 64 bytes from 10.37.66.175: icmp_seq=8 ttl=64 time=0.115 ms 64 bytes from 10.37.66.175: icmp_seq=9 ttl=64 time=0.484 ms 64 bytes from 10.37.66.175: icmp_seq=10 ttl=64 time=0.156 ms --- 10.37.66.175 ping statistics --- 10 packets transmitted, 10 received, 0% packet loss, time 8998ms rtt min/avg/max/mdev = 0.115/0.176/0.484/0.104 ms Drupal's devel.module timers show the database queries aren't running any slower on the remote DB - about 150 microseconds whether it's the local or the remote server. Profiling with XHProf shows PHP execution times that aren't out of whack, either. Number of queries doesn't seem to make a difference - we seem the same 5-10 second delay whether a page has 12 queries or 250. Any suggestions about where I should start troubleshooting here? I'm quite confused.

• How to resolve Windows Update Error 8024402F on Windows 7 Home Premium 64bit?

  - by Day

  I have been having the same problem with Windows Updates on 2 of my machines at home, both running Windows 7 Home Premium 64-bit. One of the 2 machines is a brand new install, the other has run Windows Update in the past, but is also not working now. When I manually check for updates using the Control Panel, I get error code 8024402F: I followed the link to "Get help with this error", which brings up several articles in Windows Help and Support, none of which are for this specific error code. From the help and general googling I've tried: Checking internet connectivity. Most of the help suggests that this error is caused by a general internet connectivity problem. But if you're reading this, my connection is definitely working fine. Disabling antivirus temporarily and trying to run Windows Update. This didn't help (I run AVG free) Running Control Panel - Troubleshooting - Security Systems - Fix Problems with Windows Update. This said it detected and resolved problems, but didn't help. Update using IE (as I used to in XP). Go to http://windowsupdate.microsoft.com/ redirects me to http://test.update.microsoft.com/windowsupdate/v6/vistadefault.aspx for which IE displays a "connection problem" (i.e. site unreachable) I've had the same problem for 24 hours now, so surely the Windows Update servers haven't been down this whole time? A quick check on twitter shows no worldwide outcry about Windows Update being unavailable, so is it just me? I'm based in the UK, but I notice that the http://test.update.microsoft.com/windowsupdate/v6/vistadefault.aspx URL is also unavailable using ''wget'' from my webserver in Chicago. day@ord1:~$ wget http://test.update.microsoft.com/windowsupdate/v6/vistadefault.aspx --2011-03-17 00:01:27-- http://test.update.microsoft.com/windowsupdate/v6/vistadefault.aspx Resolving test.update.microsoft.com... failed: Name or service not known. wget: unable to resolve host address `test.update.microsoft.com' day@ord1:~$ host test.update.microsoft.com Host test.update.microsoft.com not found: 3(NXDOMAIN)

• Issues with doing a P2V on Exchange 2007

  - by PokermUNKEE

  I shutdown all Exchange services on the physical box and did a convert. Everything converted fine. Server booted up no issues and I could receive email from the outside world with no issues. But I am unable to send emails internally or externally. They just sit in the Outbox. I also disabled the DHCPClient service as I didn't want the server to get an IP address from DHCP when it first came online. It came online with no IP, then I used console to assign the correct static IP address (same one on the physical server) and rebooted. I ran the Exchange Troubleshooting Agent and it gave me the following errors: The value for the '\MSExchangeIS Mailbox\Messages Queued For Submission' counter on server exchange is greater than zero (average value is 8.8) and it appears that 'MSExchangeMailSubmission' is failing to submit messages to at least one computer with the Hub Transport server role installed over the last minute. Found 1 computers with the Hub Transport server role installed in the same Active Directory site as server exchange using local Active Directory site GUID 'ce8a4367-1bf6-4825-9cac-c4e2b115c450'. Check Local Active Directory Site Hub Transport Server Role Health (Mailflow_CheckLocalBhHealth1.1.1.1.1.1.1.1) I have one Exchange server with all the roles on it. Has anyone see this before when doing a convert? Please help :(

• Nginx, memcached and cakephp: memcached module always misses cache

  - by Tim

  I've got a simple nginx configuration; server{ servername localhost; root /var/www/webroot; location / { set $memcached_key $uri; index index.php index.html; try_files $uri $uri/ @cache; } location @cache { memcached_pass localhost:11211; default_type text/html; error_page 404 @fallback; } location @fallback{ try_files $uri $uri/ /index.php?url=$uri&$args; } location ~ \.php$ { fastcgi_param MEM_KEY $memcached_key; include /etc/nginx/fastcgi.conf; fastcgi_index index.php; fastcgi_intercept_errors on; fastcgi_pass unix:/var/run/php5-fpm.sock; } } I've got a CakePHP helper that saves the view into memcached using the MEM_KEY parameter. I have tested it and it's working, however, nginx is always going to the @fallback direction. How can I go about troubleshooting this behavior? Would could the problem be?

• ASP.Net application can no longer write to DB after having run out of disk space

  - by remi.despres-smyth

  I'm a software developer troubleshooting a sticky problem on a client's production server, and I've got a bit of a problem. They have a virtual server running Windows Server 2008, SQL Server 2008 R1 and IIS7. It was provisioned with two partitions: one that has the OS (~15 Gig), and the other has IIS' web sites (another ~15 Gig). My application that's running this server has been running perfectly well, up until about an hour ago, when it started throwing System.IO.IOException: "There is not enough space on disk". As soon as my client notified me, I cleared up some space on C:\, emptied the recycle bin, and restarted SQL Server and IIS. The web server came back up and the application was running, but it no longer saves information to the database. No error message is coming up, the application can get information out of the DB, but it can no longer save data back to it. I rebooted the server, to no effect. I spoke with a sys admin at the hosting company, and he says SQL Server appears to have come up fine and the database is not in read-only mode. I confirmed that, as I can add records to tables from SQL Server Management Studio. I looked at the event log immediately after trying to save an edited record in the app, and no new events appear in there that I can tell. I'm assuming this is related to having run out of space, as it was all working fine prior to that, but I'm at a bit of a loss as to what exactly needs a kick in the pants to get going again. Can anyone help me out? What the heck is going on here?

• Reverse Proxies and AJAX

  - by osij2is

  A client of ours is using IBM/Tivoli WebSEAL, a reverse-proxy server for some of their internal users. Our web application (ASP.NET 2.0) and is a fairly straightforward web/database application. Currently, our client users that are going through the WebSEAL proxy are having problems with a .NET 3rd party control. Users who are not going through the proxy have no issues. The 3rd party control is nothing more than an AJAX dynamic tree that on each click requests all the nodes for each leaf. Now our clients claim that once users click on a node in the control, the control itself freezes in such a way that they don't see anything populate. Users see "Loading..." message appear but no new activity there afterwards. They have to leave the page and go back to the original page in order to view the new nodes. I've never worked with a reverse proxy before so I have googled quite a bit on the subject even found an article on SF. IBM/Tivoli has mentioned this issue before but this is about all they mention at all. While the IBM doc is very helpful, all of our AJAX is from the 3rd party control. I've tried troubleshooting using Firebug but by not being behind the reverse proxy, I'm unable to truly replicate the problem. My question is: does anyone have experience with reverse proxies and issues with AJAX sites? How can I go about proving what the exact issue is? Currently we're negotiating remote access so assume for the greater part that I will have access to a machine that's using the WebSEAL proxy. P.S. I realize this question might teeter on the StackOverFlow/ServerFault jurisdictional debate, but I'm trying to investigate from the systems perspective. I have no experience with reverse proxies (and I'm unclear on the benefits) and little with forwarding proxies.

• eMachine W5243 won't POST; fans run but optical drive will not open.

  - by NicciAdonai

  Symptoms are what is described in the title. The machine reacts to the power button being hit by spinning up the two fans: CPU and PSU. The hard drive (SATA) spins up as well. No other reaction. This one symptom is particularly weird, though: the optical drive will not open with the IDE cable attached, but if I unplug it from the mobo it will. I can turn the PC on with it attached, won't open; then unplug IDE while it is still on, WILL open; then plug IDE back in with the PC STILL ON, WON'T open. I have disconnected every peripheral unnecessary to POST. These include: mouse/keyboard, PCI modem, the IDE optical drive (power and data), and the SATA HDD (power and data). Video is onboard. The only two things connected are DB15 video and power cable. There were 2 512 MB DDR2 sticks of RAM in it. I have tried running it with just one of them, then switched the other in. Currently seated is a completely different 1 GB stick that I keep around for troubleshooting purposes, and I have tried it in both slots. I have replaced the CMOS battery with a used one I had lying around, and which worked in the computer it came out of. I have tested the PSU with a tester to confirm it was good, then tried connecting another PSU just in case--same symptoms. I have even tried a suggestion I found elsewhere on this site wherein one disconnects power from the PSU and then presses the PC's power button twice, thereby "resetting" the PSU. Currently I am trying yet another suggestion: turn it on and wait an inordinate amount of time for POST. Any help would be appreciated.

• RPCSS kerberos issues on imaged Windows workstations

  - by sysadmin1138

  While doing some unrelated troubleshooting I came across a set of Event Log entries that have me concerned. Machine Name: labcomputer82 Source: Security-Kerberos Event ID: 4 Event Description: The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server labcomputer143$. The target name used was RPCSS/imagemaster4.ad.domain.edu. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Please ensure that the target SPN is registered on, and only registered on, the account used by the server. This error can also happen when the target service is using a different password for the target service account than what the Kerberos Key Distribution Center (KDC) has for the target service account. Please ensure that the service on the server and the KDC are both updated to use the current password. If the server name is not fully qualified, and the target domain (AD.DOMAIN.EDU) is different from the client domain (AD.DOMAIN.EDU), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server. There are three machine names used in this message. It's generated on labcomputer82, it's attempting to talk to another lab workstation called labcomputer143, and the service in question (RPCSS) refers to the name of the machine that this machine was imaged from (and possibly also that of labcomputer143, I'm not sure). The thing that has me raising both eyebrows is that the machine named labcomputer82 is attempting to use an SPN of RPCSS/imagemaster4.ad.domain.edu. The SPN attribute on the computer object in AD looks just fine. It has all the names it should have. Of the over 3,000 computer objects in our AD domain, somewhere around 1,700 of the are computer-lab seats that are frequently imaged. If we're doing something wrong, I'd like to know in time to get our procedures modified (and people retrained) for fall quarter. But if this is normal for imaged machines, I'll just continue ignoring these.

• Iverter, inverter cable, or a display cable?

  - by krebshack

  I was recently hired at a small repair shop. I work indoors while my boss does on site calls for small businesses. I have to troubleshoot and fix laptop screens a few times a week and this is why I'm posting this question. I'm having trouble figuring out how to stream line the troubleshooting process. For example, how do I determine whether the inverter is broken while also determining that the inverter cable is not. How can I quickly decide that the inverter cable is broken while knowing that the inverter is most likely not broke. Or how do I know that it's just the display cable? It seems like this is a good way to approach things: "It could be the inverter, backlight, or the LCD panel itself. Backlight failure is usually hinted at by a pink hue to everything. Inverter failure usually results in the dimming of images on the screen to the point where the backlight is not even on (the inverter provides power to the backlight)" Source. While remembering that things "like flickering, screen freeze in dark image and [a] corner starts to get brighter" point to a "failure in the LCD panel itself, though it could just as easily be a loose data cable connected to the back of the LCD." Source. In short, I'm soliciting advice that anyone might have on how to quickly make the best decision about what's causing problems with laptops display. Thank you.

• some PDF's to iPhones via ActiveSync are corrupt

  - by longneck

  we have two server applications (one .NET/ASP web app, the other a native Windows app) that generate PDF's that are then emailed to our users on Exchange 2010. the apps deliver the emails to the Exchange server via SMTP, and our iPhone/iPad users receive their email via activesync. pretty much all of the PDF's generated by the web app and many of the PDF's generated by the Windows app fail to open on an iPhone or iPad. tapping the attachment shows the screen that would display the PDF with the name of the file at the top but the bottom of the screen is completely grey. one thing i have figured out is that the attachment on the iPad is uuencoded. forwarding the attachment to another email address shows the uuencoded format. here's a sample: begin 600 unknown M)5!$1BTQ+C0-)>+CS],-"C8@,"!O8FH\/"](6S8U-B`Q-#A=+TQI;F5A<FEZ M960@,2]%(#DQ-#8O3"`Q,S`Q.2].(#$O3R`Y+U0@,3(X-3,^/@UE;F1O8FH- ---snip--- M,C8T,"`P,#`P,"!N#0IT<F%I;&5R#0H\/"]3:7IE(#8^/@T*<W1A<G1X<F5F .#0HQ,38-"B4E14]&#0H` ` end whereas the normal version of the file looks like a normal PDF: %PDF-1.4 %âãÏÓ 6 0 obj<</H[656 147]/Linearized 1/E 9698/L 13571/N 1/O 9/T 13405>> ---snip--- trailer <</Size 6>> startxref 116 %%EOF so i think the problem is that the attachment is being double uuencoded somewhere, or the iPhone is failing to recognize that the attachment is uuencoded and not decoding it. any suggestions on where to begin troubleshooting this problem?

• High load average, low CPU and IO (Centos 5.7)

  - by Ben

  A Drupal 7 site with CiviCRM, after running smoothly for a year on a 1&1 VPS suddenly became unresponsive. Now pages eventually load, but can take more than a minute. Looking at resource use in Virtuozzo, the load average carries a warning, and has remained above 1. While I understand this isn't particularly high, this is a change from when the site was working. Here is a typical snapshot of top: top - 03:10:32 up 3:21, 1 user, load average: 1.16, 1.22, 1.30 Tasks: 43 total, 1 running, 42 sleeping, 0 stopped, 0 zombie Cpu(s): 0.1%us, 0.1%sy, 0.1%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2097152k total, 1015112k used, 1082040k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached CPU idle level never seems to go much below 70%. wa is virtually always at 0. There appears to be lots of free memory.

Instead they suggested an upgrade :) I've looked for processes that might be causing this, examined MySQL showprocesslist, and restarted the container with no result. Does anyone have more troubleshooting suggestions or insights?

• Embedded Spotlight does not function in Outlook 2011

  - by syntaxcollector

  I have a rather strange problem. I manage a network of about 35 Mac, and we all recently switched from Mail.app to Outlook 2011 (Please don't debate this, I've already had this conversation ad nauseum) We are using network home directories (NHD) server from a Windows file server over the SMB protocol. The problem I'm having is Spotlight does not function inside of Outlook. But ONLY inside of Outlook. The global Spotlight can find all email and contacts with Outlook, but the embedded Spotlight cannot. As a test, I took one of my users and switched them from a network home directory to a portable home directory (PHD) (this means the home folder was copied to the local hard drive). This resulted in a working Spotlight within Outlook, as soon as I switched the user back to an NHD, however, it stopped working. I have already tried erasing the Spotlight index and killing the process to force re-indexing. I have exhausted all Spotlight troubleshooting, and since the global is working that is obviously not the issue. I believe it has something to do with the Spotlight plugin Microsoft wrote that is located in /Library/Spotlight. Any ideas?

• Windows roaming profile when creating a new user profile

  - by molecule

  When a particular user is having a lot of problems with Windows XP e.g. applications crashing, unresponsive applications (which used to work), and as a general troubleshooting practice for a domain user, I normally rename that user's old profile and get him/her to logon to create a "fresh" profile (on the same PC). More often than not, this will solve the problem albeit some reconfiguration i.e. Outlook, Excel add-ins etc. As I took over the systems admin role from another administrator, I would like to know what is the easiest way to find out (either through a third party or some Windows administrative tool) what settings are carried over if the profile is a Roaming Profile. I tested creating a new user profile for one of my users and it seems basic Outlook settings such as the user's mailbox and PSTs are carried over automatically when I create a new user profile. I suspect this is done through a batch file loaded as part of the login script. However, my knowledge of scripting is limited and I don't want any corruptions to be carried over to the new profile. Can someone share their experiences on this? Thanks in advance.

• How to create an MST for silent install using Orca?

  - by Sanarothe

  Hi. I'm trying to deploy 7zip via GPO; I assigned the original MSI, but the package installation simply doesn't take place. What I've gathered is that I need to create an MST. In the spirit of trying to learn as much as possible about it, I've opted to use Orca rather than a third-party automagic tool, but I'm at a loss as to which fields to edit. So far the only change that I've made is to give the license accepted checkbox a value of "1" instead of pointing to another key that, still, just gave it a value of "1." So, to give this some structure, How does (Or what criteria should I consider) creating a MST make the install noninteractive/silent? Do you have to manually reconfigure the MSI to simply not perform the GUI aspects? Or do I have to execute the program in silent mode after defining the variables the the installer requests? (Though, of course, it seems that would defeat the purpose of the MST) How do I determine which fields I need to edit? I've loaded the installer and it takes three inputs: License acceptance, feature set and installation location. I want all of the default values: I'm just trying to deploy it at all, not customize the installation. I BELIEVE that I should be messing with some values in the Registry table, but I really don't know. If I'm not asking the right questions, can someone point me to a THOROUGH resource or documentation for this process? I've already gone over the technet articles on basic Orca use and deployment, but I couldn't really find anything on creating MST that didn't involve a third party program in which one runs a 'dummy' installer to get the before and after snapshots. Thank you very much, Cameron UPDATE: After spending the day troubleshooting, I finally got my server to send out 7zip, but not until I had also assigned firefox. Not sure why it didn't want to send out 7zip by itself, but I also had some domain naming problems. Thanks for the input (GPResult helped enormously.)

• How do I troubleshoot a segfault in Ubuntu that occurs when typing a bogus command?

  - by Alan

  We've got a production server running Ubuntu 11.10. We're encountering segfaults that appear under various conditions. The simplest reproducible case is when we login to an ssh session as our administrative user and enter a bogus command. You'd expect the standard "command not found" error message. Instead, we get a segfault in python. The user's default shell is /bin/bash. For example: $ asdf Segmentation fault Info from /var/log/syslog: Jul 6 15:39:20 PROD001 kernel: [2155960.605695] python[7873]: segfault at 0 ip (null) sp 00007fffd030b808 error 14 in python2.7[400000+233000] Some details about the server: $ uname -a Linux PROD001 3.0.0-16-server #29-Ubuntu SMP Tue Feb 14 13:08:12 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/issue Ubuntu 11.10 \n \l Before we ask the IT department to reinstall the O.S., I'd like to understand what got us here. The system and/or this particular user's environment is suspect. Many people have touched this server over the past year, so I'm wondering if it is missing libraries, incorrectly installed packages, etc. I'm hoping that if we can understand what's going wrong in this case, it will help explain why we're getting segfaults in a couple of other scenarios. Any tips on troubleshooting this segfault will be appreciated!

• DFS replication and the SYSTEM user (NTFS permissions)

  - by HopelessN00b

  Question for which I'm having trouble finding an answer on Google or Technet... Does granting the SYSTEM user permissions to DFS-shared files and folders have any effect on DFS replication? (And while we're at it, is there any good reason not to let SYSTEM have permissions to DFS-shared files?) It comes up because I have a collection of DFS namespaces and folders that I'm not able to make someone else's problem, and while troubleshooting a problem where one DFS replica just wasn't replicating with another for no discernible reason, I observed that the SYSTEM didn't have any permissions granted to any of the files or folders in the folder in question. So I set SYSTEM to have full control and propagated it down, and our DFS health diagnostic reports went from showing a backlog of ~80 files to a backlog of ~100,000... and things started replicating, including a number of files that had been missing on one server or the other (so more than just the permissions changes started replicating). Naturally, this made me curious as to whether or not DFS needs the SYSTEM account to have permissions to do its work, or if perhaps it was just any change to folder tree in question that prompted DFS to jump into action. If it matters, our DFS namespaces were set up under 2000/2003, and I have just recently finished upgrading all the servers to 2008 R2 or 2012 (with UAC enabled, blech), but have not yet gotten around to raising the DFS namespace functional levels to Server 2008. (And bonus points if anyone has an official Microsoft article on NTFS file permissions and the SYSTEM account as it pertains to DFS or network files.)

• Fedora 17 - Dropping into debug shell after attempted partitioning

  - by i.h4d35

  So I tried creating a new partition on Fedora 17 using fdisk as follows: Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (2048-823215039, default 2048): Using default value 2048 Last cylinder or +size or +sizeM or +sizeK (1-9039, default 9039): +15G Once this was done,instead of formatting the partition I created, I ran the partprobe command to write the changes to the partition table. On rebooting the computer, it drops to the debug shell and gives me the error as follows: dracut warning:unable to process initqueue dracut warning:/dev/disk/by-uuid/vg_mymachine does not exist dropping to debug shell dracut:/# While trying to run fsck on the said partition from the debug shell, it says "etc/fstab not found" and inside /etc I see a fstab.empty file. Is it now possible to retrieve what I have from the computer? Any help would be appreciated. Thanks in advance Edit: I've also tried the following steps for additional troubleshooting: I tried to boot using the Fedora disk and tried the rescue mode - says no Linux partition detected. I tried to create an fstab file by combining the entries from blkid and the /etc/mtab file and using the UUIDs from the mtab file - It didn't work. As soon as I rebooted the machine, it promptly dropped me in to the debug shell and the fstab file which i created wansn't there anymore in /etc (part of this solution)

• Windows roaming profile when creating a new user profile

  - by molecule

  Hi all, When a particular user is having a lot of problems with Windows XP e.g. applications crashing, unresponsive applications (which used to work), and as a general troubleshooting practice for a domain user, I normally rename that user's old profile and get him/her to logon to create a "fresh" profile (on the same PC). More often than not, this will solve the problem albeit some reconfiguration i.e. Outlook, Excel add-ins etc. As I took over the systems admin role from another administrator, I would like to know what is the easiest way to find out (either through a third party or some Windows administrative tool) what settings are carried over if the profile is a Roaming Profile. I tested creating a new user profile for one of my users and it seems basic Outlook settings such as the user's mailbox and PSTs are carried over automatically when I create a new user profile. I suspect this is done through a batch file loaded as part of the login script. However, my knowledge of scripting is limited and I don't want any corruptions to be carried over to the new profile. Can someone share their experiences on this? Thanks in advance.

• Dual booting Linux/Win7, Grub refuses to load Win7

  - by JohnB

  Decided to give Linux Mint a try (Ubuntu's interface annoys me), so I installed it with the intention of dual booting with Windows 7. Installation went fine, but now I can only boot into Linux Mint. Grub lists two Windows 7 menu options, but selecting either of them causes an "unknown file system" error and dumps me into a Grub recovery prompt. There, I have to manually reset the root and prefix options, as they reset hd0,msdos6 when they should be hd0,msdos5. I ran Boot Repair twice, once to fix grub errors, once to rebuild the MBR, but it didn't fix anything. Here is the log: http://paste.ubuntu.com/1029675/ fdisk output: Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 1486249145 743021149 7 HPFS/NTFS/exFAT /dev/sda3 1486249982 1953523711 233636865 5 Extended /dev/sda5 1486249984 1945141247 229445632 83 Linux /dev/sda6 1945143296 1953523711 4190208 82 Linux swap / Solaris grub.cfg: ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os { insmod part_msdos insmod ntfs set root='(hd0,msdos1)' search --no-floppy --fs-uuid --set=root 86184D18184D091F chainloader +1 } menuentry "Windows 7 (loader) (on /dev/sda2)" --class windows --class os { insmod part_msdos insmod ntfs set root='(hd0,msdos2)' search --no-floppy --fs-uuid --set=root 56D84F84D84F60FB chainloader +1 } ### END /etc/grub.d/30_os-prober ### I have found a few similar troubleshooting guides so far, but so far no amount of updating/configuring Grub has been successful. Last resort is, I suppose, use the W7 recovery disc and start over. Thanks in advance! Linux Mint 13 Maya, 64-bit Windows 7 Home Edition, 64-bit

• Windows Server 2008 network speed slow, Xen 3.4.3 HVM ISO

  - by Elliot.Bradshaw

  I've setup a VM running Windows Server 2008 on a host node running Xen 3.4.3-5 and the following kernel: 2.6.18-308.1.1.el5xen #1 SMP Wed Mar 7 05:38:01 EST 2012 i686 i686 i386 GNU/Linux The network speed on the VM is very slow--using the online speed tests I can only get it up to 8-9mbps. The line is 100mbps burstable and the host node has no problem achieving those speeds. If it setup a VM running CentOS, it too has no problems achieving those speeds. I've done some pretty exhaustive troubleshooting, but nothing has helped: New VM installations of Win2k8 do have the same network problem. Upgrading to most recent kernel-xen did not help (2.6.18-308.1.1.el5xen). Upgrading from xen 3.4.0 to xen 3.4.3-5 did not help. Disabling Windows firewall, etc did not help. Changing network card device config from auto negotiation to manually be 100mbps full duplex did not help. Changing the network receive buffer packet size did not help (tried all combos from 64k to 8k). At this point I'm pretty much out of ideas--any help would be appreciated!

• Authenticating Active Directory Users to Mac OS X Mavericks Server L2TP VPN Service

  - by dean

  We have a Windows Server 2012 Active Directory Infrastructure that consists of two domain controllers. Bound to the Active Directory Domain is a Mac OS X Mavericks Server 10.9.3. The server runs Profile Manager and VPN Services. My Active Directory users are able to authenticate to the Profile Manager, but not the VPN. I have found several threads on other forums of other users reporting similar issues, here is just one of many references: https://discussions.apple.com/thread/5174619 It appears as though the issue is related to a CHAP authentication failure. Can anyone suggest what next troubleshooting steps I might take? Is there a way to liberalize the authentication mechanism to include MSCHAP? Here is an excerpt of the transaction from the logs.
