• Vista install works on one computer, but bluescreens another (on which Vista is known to work)

  - by Ken

  I hope my explanations make some sense -- please ask for clarification if they don't. I had a computer running Windows Vista (Ultimate, 64-bit). All was well! Then one day there was a nasty power surge at the office, and it died. (We didn't have surge protectors at the office, unfortunately. I assumed our lines were conditioned elsewhere, or was not an issue here. Oops.) After some testing, it was determined that the PSU, motherboard, and RAM were bad. While waiting for new hardware to arrive, I put my hard disk in a spare PC which had identical parts (mobo/CPU/RAM/PSU/video). Everything worked perfectly. The only way I could even tell it wasn't my computer is because Vista asked to re-activate itself with the new hardware, which worked fine, too. So the hard disk seems OK. Then the new parts arrived. The old motherboard model is no longer manufactured, so it's a new one with the same CPU/RAM/videocard/etc. slots. The PSU is also new, while the RAM I'm using is from the spare PC mentioned above. When I put it together and tried booting with my old hard disk, it starts to boot Windows, and then (fairly early in the process) gives a bluescreen and immediately reboots (so I can't see whatever the bluescreen is trying to tell me). I tried "safe mode", which also bluescreened. I tried booting the Vista DVD and running the repair utility, which found a Vista install, confirmed that it would not boot, and, eventually, declared that it was unable to repair it. I installed Vista fresh on a new hard disk, with the new mobo/etc., and it works perfectly. (That's what I'm running now.) I've also booted a Linux CD here, which ran great, and I've run Memtest86+ for a while, which found no errors. So all the hardware apart from the old hard disk seems OK, too. I don't think the problem is with my old Vista hard disk, since I used that with another mobo/CPU just fine. I don't think it's any other part of the new hardware, since I'm able to use it (and test it) with no trouble. It's just the combination of my old Vista install plus the new PC hardware that's not happy. I can get my data off my old hard disk and onto my new hard disk, and reinstall my apps, but it would be nice if I could fix things so I could continue to use my old hard disk as before. The latest hypothesis I've heard is that Vista had trouble with the new hardware (i.e., motherboard), but we have no idea what to do about that (except Safe Mode, which didn't work). Suggestions? Hypotheses for what's not right about this combination of Vista install and motherboard? Thanks!

• Too many Tunnel Adapter Interfaces

  - by Tomas Lycken

  If I open a command prompt on my machine and type ipconfig /all, I see lots of Tunnel adapter Local Area Connection* 9: Media state . . . . . . . . . . . . . : Media disconnected Connection-specific DNS Sufficx . . . : Description . . . . . . . . . . . . . : Microsoft 6to4 Adapter #5 Physical address. . . . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . . . : No Autoconfiguration Enabled . . . . . . : Yes In fact, they're so many that my "real" adapters are pushed out of the stack, and can't be seen anymore. Is there any flag I can use on ipconfig to hide all virtual interfaces? Or is there some other way around this problem? Since they always say "Media disconnected" I suppose disabling could be an option, but if possible I'd rather not turn any functionality off. I just want to control what output I get from ipconfig. Also, I know these are related to IPv6 stuff. However, most of what I find on google merely states what these are, and that they're harmless - nothing about hiding/removing them.

• Best available technology for layered disk cache in linux

  - by SpliFF

  I've just bought a 6-core Phenom with 16G of RAM. I use it primarily for compiling and video encoding (and occassional web/db). I'm finding all activities get disk-bound and I just can't keep all 6 cores fed. I'm buying an SSD raid to sit between the HDD and tmpfs. I want to setup a "layered" filesystem where reads are cached on tmpfs but writes safely go through to the SSD. I want files (or blocks) that haven't been read lately on the SSD to then be written back to a HDD using a compressed FS or block layer. So basically reads: - Check tmpfs - Check SSD - Check HD And writes: - Straight to SSD (for safety), then tmpfs (for speed) And periodically, or when space gets low: - Move least frequently accessed files down one layer. I've seen a few projects of interest. CacheFS, cachefsd, bcache seem pretty close but I'm having trouble determining which are practical. bcache seems a little risky (early adoption), cachefs seems tied to specific network filesystems. There are "union" projects unionfs and aufs that let you mount filesystems over each other (USB device over a DVD usually) but both are distributed as a patch and I get the impression this sort of "transparent" mounting was going to become a kernel feature rather than a FS. I know the kernel has a built-in disk cache but it doesn't seem to work well with compiling. I see a 20x speed improvement when I move my source files to tmpfs. I think it's because the standard buffers are dedicated to a specific process and compiling creates and destroys thousands of processes during a build (just guessing there). It looks like I really want those files precached. I've read tmpfs can use virtual memory. In that case is it practical to create a giant tmpfs with swap on the SSD? I don't need to boot off the resulting layered filesystem. I can load grub, kernel and initrd from elsewhere if needed. So that's the background. The question has several components I guess: Recommended FS and/or block layer for the SSD and compressed HDD. Recommended mkfs parameters (block size, options etc...) Recommended cache/mount technology to bind the layers transparently Required mount parameters Required kernel options / patches, etc..

• Simple Backup Strategy for Amazon EC2 instances / volumes?

  - by minerj

  You have entered Introductory Backups for Amazon EC2 EBS-backed Windows Images 010... I have been browsing my brains out to find a simple backup strategy for our single windows 2008 server running SharePoint Services. This is an EBS-backed image of one server with one data volume. I don’t need anything exotic. I only need a “daily” backup (losing a day’s worth of data is not catastrophic). We have created and saved an EBS backed AMI image (Windows 2008) we are comfortable using. We started off making backups by simply creating a new EBS AMI image. This is really simple, but the running server is put offline during the first 10 – 15 minutes of creating the image – not ideal. The standard way of creating backups would seem to be creating snapshots of volumes attached to a running instance. Again it’s pretty simple and the server remains usable during the snapshot generation. The apparent Catch-22 is that you can’t simply launch a new instance directly from a snapshot. I know how to bundle a running instance to S3 storage and then register the AMI from the S3 bucket. This does allow me to capture a backup of a running instance and, if the running instance is lost, register the AMI from the S3 bucket and launch the new AMI to recover the instance, but this seems really convoluted and it seems ridiculous to have to juggle back and forth between the AWS Console and the S3 Organizer plug-in for Firefox to get this accomplished. (Please don't mention the command line approach, this is an 010 level course). From playing around with EBS-backed images, the following approach appears to work for me (all done within the AWS Console): 1.For your backups, simply snapshot the system volume (/dev/sda1) as needed. 2.If you lose your running instance, do the following: a.Create a new volume from your last snapshot backup b.Launch another instance of your starting AMI (must be EBS-backed) c.Stop this instance. d.Detach the existing system volume from the new stopped instance and discard. e.Attach the newly created volume as system volume (/dev/sda1) to the stopped instance. f.Re-start the new instance. I have tested this out a couple of times and it seems to work for me. Question: Is there anything wrong with this approach?

• dhcp-snooping option 82 drops valid dhcp requests on 2610 series Procurve switches

  - by kce

  We are slowly starting to implement dhcp-snooping on our HP ProCurve 2610 series switches, all running the R.11.72 firmware. I'm seeing some strange behavior where dhcp-request or dhcp-renew packets are dropped when originating from "downstream" switches due "untrusted relay information from client". The full error: Received untrusted relay information from client <mac-address> on port <port-number> In more detail we have a 48 port HP2610 (Switch A) and a 24 port HP2610 (Switch B). Switch B is "downstream" of Switch A by virtue of a DSL connection to one of Switch A ports. The dhcp server is connected to Switch A. The relevant bits are as follows: Switch A dhcp-snooping dhcp-snooping authorized-server 192.168.0.254 dhcp-snooping vlan 1 168 interface 25 name "Server" dhcp-snooping trust exit Switch B dhcp-snooping dhcp-snooping authorized-server 192.168.0.254 dhcp-snooping vlan 1 interface Trk1 dhcp-snooping trust exit The switches are set to trust BOTH the port the authorized dhcp server is attached to and its IP address. This is all well and good for the clients attached to Switch A, but the clients attached to Switch B get denied due to the "untrusted relay information" error. This is odd for a few reasons 1) dhcp-relay is not configured on either switch, 2) the Layer-3 network here is flat, same subnet. DHCP packets should not have a modified option 82 attribute. dhcp-relay does appear to be enabled by default however: SWITCH A# show dhcp-relay DHCP Relay Agent : Enabled Option 82 : Disabled Response validation : Disabled Option 82 handle policy : append Remote ID : mac Client Requests Server Responses Valid Dropped Valid Dropped ---------- ---------- ---------- ---------- 0 0 0 0 SWITCH B# show dhcp-relay DHCP Relay Agent : Enabled Option 82 : Disabled Response validation : Disabled Option 82 handle policy : append Remote ID : mac Client Requests Server Responses Valid Dropped Valid Dropped ---------- ---------- ---------- ---------- 40156 0 0 0 And interestingly enough the dhcp-relay agent seems very busy on Switch B, but why? As far as I can tell there is no reason why dhcp requests need a relay with this topology. And furthermore I can't tell why the upstream switch is dropping legitimate dhcp requests for untrusted relay information when the relay agent in question (on Switch B) isn't modifying the option 82 attributes anyway. Adding the no dhcp-snooping option 82 on Switch A allows the dhcp traffic from Switch B to be approved by Switch A, by virtue of just turning off that feature. What are the repercussions of not validating option 82 modified dhcp traffic? If I disable option 82 on all my "upstream" switches - will they pass dhcp traffic from any downstream switch regardless of that traffic's legitimacy? This behavior is client operating system agnostic. I see it with both Windows and Linux clients. Our DHCP servers are either Windows Server 2003 or Windows Server 2008 R2 machines. I see this behavior regardless of the DHCP servers' operating system. Can anyone shed some light on what's happening here and give me some recommendations on how I should proceed with configuring the option 82 setting? I feel like i just haven't completely grokked dhcp-relaying and option 82 attributes.

• Windows 7 is shutting down unexpectedly, according to the logs.

  - by dlamblin

  Here's a message from my eventvwr EventLog (Windows Logs System): The previous system shutdown at 11:51:15 AM on ?7/?29/?2009 was unexpected. This is funny because I was wondering why the system shut down while I was playing Civilizations IV full screen. Now I know. It was unexpected. Has anyone encountered and resolved this? A little background: I am running Windows 7 RC inside VMWare Fusion 2 (just updated a few months back) on a MacBook (Bitterly not Pro) aluminum-body. Windows 7 occasionally will shut down. This isn't a quick turn-off, it's a shutdown where all the programs are exited, the system waits until they quit (and Civ4 doesn't prompt me to save), it even installed Windows Updates before restarting. And yes it is restarting right after the shutdown. Because I run a game in full screen mode I do not notice any dialog with a countdown timer or anything like that that might be a warning. As I have iStat on my dashboard widgets I can see about 8 temperature monitors. I have seen the CPU get up to 74C before, but during the shutdown, though it seemed hot to the touch (always is), it read 61C for the CPU, 60C for heatsink A, 50C for heatsink B and in the 30s-40s for the enclosure and harddrives. As I type this now, the temps are actually higher, so I don't think the temperature caused it. I have at least six such events dating first from 5/17 which was a week after installing Windows 7. I did find one information level warning from USER32 in the system log that says: The process C:\Windows\system32\svchost.exe (DLAMBLIN-WIN7) has initiated the restart of computer DLAMBLIN-WIN7 on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Recovery (Planned) Reason Code: 0x80020002 Shutdown Type: restart Comment: And another 15 minutes before that from Windows Update: Restart Required: To complete the installation of the following updates, the computer will be restarted within 15 minutes: - Cumulative Security Update for Internet Explorer 8 for Windows 7 Release Candidate for x64-based Systems (KB972260) Which I think kind of explains it. Though I don't know why restarting after an update would create an error event of "shutdown was unexpected", isn't that pretty odd? Now, how do I set it to never restart after an update unless I click something. Application of solution: As fretje reminded me, there's a couple of configurable settings for this, in windows 7 they're much in the same place as in Windows 2000 SP3 and XP SP1. Running gpedit.msc pops up a window that looks like: Windows 7 has changed the order and added a couple of newer options I've italicized: Do not display 'Install Updates and Shut Down' in Shut Down Windows dialog box Do not adjust default option to 'Install Updates and Shut Down' in Shut Down Windows dialog box Enabling Windows Power Management to automatically wake up the system to install scheduled updates Configure Automatic Updates Specify intranet Microsoft update service location Automatic Updates detection frequency Allow non-administrators to receive update notifications Turn on Software Notifications Allow Automatic Updates immediate installation Turn on recommended updates via Automatic Updates No auto-restart with logged-on users for scheduled Automatic Updates Re-prompt for restart with scheduled installations.

• Double Layer DVD+R burning problem - I/O Error

  - by Mehper C. Palavuzlar

  I have a modern PC (Quad Core CPU, 4 GB RAM, Win7 Home Premium 64-bit) but I have a problem with burning .dvd images to Double Layer (8.5 GB) DVDs. I wasted too many DVD+R DL discs but to no avail. Here is a short explanation of what I did: I'm using ImgBurn v2.5.0.0 (latest version). I'm trying to burn an image file (.dvd) which is together with the related .iso file in the same folder. In ImgBurn, I select the file with .dvd extension, and set writing speed to 2.4x. Burning process starts normally, but around 7% of the process, it gives a I/O Write Error, which is as follows: I wasted 3 discs (Magic, Made in Taiwan, DVD+R DL, 8.5 GB) trying the same thing. My DVD writer is LG GH22NP20 with IDE connection type. I updated its firmware from 1.04 to 2.00 but no success in burning again. Then my cousin brought his LG (an older model) which, he claims, was successful in writing DL discs with the same brand (Magic). I plugged off my LG and plugged the older one in, and tried to burn the image again. It also gave an I/O Error even without standing till 7%. I tried another burning program (CloneCD), but failed again. Then I bought other brands (TDK and VERBATIM) and tried to burn the image. Burning process started successfully, but around 14% (for Verbatim) and 25% (for TDK) failed again. Here is a screeny from ImgBurn: I've burned lots of 4.7 GB DVD+Rs and DVD-Rs successfully, even without a single error, with this LG DVD writer, but this case is very bothering for me. What should I do? Should I buy a new DVD writer other than LG? Could this be related to Windows or my hardware configuration? Thanks for your help. Edit: My burner works on my cousin's machine. So the problem must be related to my system. What could be the reason? Latest news: I borrowed an external USB DVD writer from a friend, which is PHILIPS SPD3000CC (an old model). Guess what! It's burning DVD+R DLs successfully! How come an internal DVD writer of a brand new computer system cannot burn DL DVDs? Now I'm considering buying a new internal DVD writer with not IDE, but SATA connection...

• How to know the source of certain TCP traffic on AIX

  - by A.Rashad

  We have two AIX boxes, one for production system and another for testing. both systems are running ATM machine switches, where the ATM device is connected via TCP socket. we had an issue on production system where the machine would power off or get disconnected but the netstat -na | grep <IP of machine > would still mention that the socket is up when simulated that case on the UAT environment, the problem did not happen, where the socket would terminate in 3 to 5 minutes. when sniffed on the traffic between the machine and ATM we found that no traffic takes place on production while there is some sort of heartbeat on UAT. but it is not initiated by the application. $>tcpdump | grep -v "10.2.2.71" | grep -v "HSRP" | grep "10.3.1.30" tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en6, link-type 1, capture size 96 bytes 09:08:13.323421 IP server073.afs3-callback > 10.3.1.30.impera: . 278204201:278204202(1) ack 3307884029 win 164 09:08:13.335334 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:08:23.425771 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:08:23.425789 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 09:09:13.628985 IP server073.afs3-callback > 10.3.1.30.impera: . 0:1(1) ack 1 win 164 09:09:13.633900 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:09:23.373634 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:09:23.373647 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 while on production, that traffic is not there. we want to know where this traffic is initiated from to implement on production to sense disconnection our comms parameters are: tcp_keepcnt = 2 tcp_keepidle = 100 tcp_keepinit = 150 tcp_keepintvl = 150 tcp_finwait2 = 1200 can anyone help?

• swapping or thrashing with vast amounts of unmapped pagecache

  - by Marco

  EDIT: I noticed that this is more appropriate for superuser.com, I apologize. I don't know how to delete this question. I'm using kubuntu jaunty (i386 32bit), kernel 2.6.28-13-generic. I've 4Gb of RAM, of which only 3317Mb are seen by the system (I guess because of the 32bit system). I'm seeing that the pagecache utilization is continually growing, up to the point that the system is unusable (after a few days). This happens also when I don't do anything (all user applications closed and the bare minimum of services enabled). If enabled, the system starts to use swap space (using it all in the end). Even if swap is disabled, disk activity becomes continuous, with the system unresponsive.

• svn 503 error when commit new files

  - by philipp

  I am struggling with a strange error when I try to commit my repository. I have a V-server with webmin installed on it. Via Webmin I installed an svn module, created repositories and everything worked fine until three days ago. Trying to commit brings the following error: Commit failed (details follow): Server sent unexpected return value (503 Service unavailable) in response to PROPFIND request for '/svn/rle/!svn/wrk/a1f963a7-0a33-fa48-bfde-183ea06ab958/RLE/.htaccess' Server sent unexpected return value (503 Service unavailable) in response to PROPFIND request for '/svn/rle/RLE/.htaccess' I google everywhere and found only very few solutions. One indicated that a wrong error document is set, another one dealt about the problem that filenames might cause this error and last but not least a wrong proxy configuration in the local svn config could be the reason. After trying all of the solutions suggested I could not reach anything. Only after a server reboot there was a little difference in the error-message, telling me that the server was not able to move a temp file, because the operation was permitted. So I also controlled the permissions of the svn directory, but also with no success. An svn update than restored the "normal" error from above and nothing changed since then. The only change I made on the server, I guess that this could be the reason why svn does not work anymore, was to install the php5_mysql module for apache via apt-get install php5_mysql. Atg the moment I have totally no idea where I could search. I don't know if the problem is on my server or in my repository and I would be glad to get any hint to solve this. Thanks in advance Greetings philipp error log: [Tue Oct 25 19:23:02 2011] [error] [client 217.50.254.18] Could not create activity /svn/rle/!svn/act/d8dd436f-d014-f047-8e87-01baac46a593.

I think this is part of the repository. So, I just just want to admit that i tried to reach the repository via Browser and i worked, I could see everything, so the error only occurs when I try to commit new files. I also created a second repository and tried to commit files in there, what gave me the same error.

• Linux HA cluster w/Xen, Heartbeat, Pacemaker. domU does not failover to secondary node

  - by Kendall

  I am having the followig problem with an OenSuSE + Heartbeat + Pacemaker + Xen HA cluster: when the node a Xen domU is running on is "dead" the Xen domU running on it is not restarted on the second node. The cluster is setup with two nodes, each running OpenSuSE-11.3, Heartbeat 3.0, and Pacemaker 1.0 in CRM mode. For storage I am using a LUN on an iSCSI SAN device; the LUN is formatted with OCFS2 and managed with LVM. The Xen domU has two logical volumes; one for root and the other for swap. I am using IPMI cards for STONITH devices, and a dedicated ethernet link for heartbeat communications. The ha.cf file is as follows: keepalive 1 deadtime 10 warntime 5 udpport 694 ucast eth1 auto_failback off node dhcp-166 node stage use_logd yes crm yes My resources look as follows: shocrm(live)configure# show node $id="5c1aa924-bba4-4f95-a367-6c9a58ac4a38" dhcp-166 node $id="cebc92eb-af24-4833-aaf0-672adf80b58e" stage primitive Xen-Util ocf:heartbeat:Xen \ meta target-role="Started" \ operations $id="Xen-Util-operations" \ op start interval="0" timeout="60" start-delay="0" \ op stop interval="0" timeout="120" \ params xmfile="/etc/xen/vm/xen-util" primitive my-stonith stonith:external/ipmi \ params hostname="dhcp-166" ipaddr="192.168.3.106" userid="ADMIN" passwd="xxx" \ op monitor interval="2m" timeout="60s" primitive my-stonith2 stonith:external/ipmi \ params hostname="stage" ipaddr="192.168.3.105" userid="ADMIN" passwd="xxx" \ op monitor interval="2m" timeout="60s" property $id="cib-bootstrap-options" \ dc-version="1.0.9-89bd754939df5150de7cd76835f98fe90851b677" \ cluster-infrastructure="Heartbeat" The Xen domU config file is as follows: name = "xen-util" bootloader = "/usr/lib/xen/boot/domUloader.py" #bootargs = "xvda1:/vmlinuz-xen,/initrd-xen" bootargs = "--entry=xvda1:/boot/vmlinuz-xen,/boot/initrd-xen" memory = 4096 disk = [ 'phy:vg_xen/xen-util-root,xvda1,w', 'phy:vg_xen/xen-util-swap,xvda2,w', ] root = "/dev/xvda1" vif = [ 'mac=00:16:3e:42:42:06' ] #vfb = [ 'type=vnc,vncunused=0,vnclisten=192.168.3.172' ] extra = "" Say domU "Xen-Util" is running on node "stage"; if "stage" goes down, "Xen-Util" does not restart on node "dhcp-166". It seems to want to try as an "xm list" will show it for a few seconds and if you "xm console xen-util" it will give a message like "copying /boot/kernel.gz from xvda1 to /var/lib/xen/tmp/kernel.a53gs for booting". However, it never gets past that, eventually gives up, and no longer appears in "xm list". Now, when node "stage" comes back online after being power cycled, it detects that "Xen-Util" isn't running, and starts it (on stage). I've tried starting "Xen-Util" on node "dhcp-166" without the cluster running, and it works fine. No problems. So, I know it works in that respect. Any ideas? Thanks!

• How to allow local LAN access while connected to Cisco VPN?

  - by Ian Boyd

  How can I maintain local LAN access while connected to Cisco VPN? When connecting using Cisco VPN, the server has to ability to instruct the client to prevent local LAN access. Assuming this server-side option cannot be turned off, how can allow local LAN access while connected with a Cisco VPN client? I used to think it was simply a matter of routes being added that capture LAN traffic with a higher metric, for example: Network Destination Netmask Gateway Interface Metric 10.0.0.0 255.255.0.0 10.0.0.3 10.0.0.3 20 <--Local LAN 10.0.0.0 255.255.0.0 192.168.199.1 192.168.199.12 1 <--VPN Link And trying to delete the 10.0.x.x -> 192.168.199.12 route don't have any effect: >route delete 10.0.0.0 >route delete 10.0.0.0 mask 255.255.0.0 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 192.168.199.12 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 0x3 And while it still might simply be a routing issue, attempts to add or delete routes fail. At what level is Cisco VPN client driver doing what in the networking stack that takes overrides a local administrator's ability to administer their machine? The Cisco VPN client cannot be employing magic. It's still software running on my computer. What mechanism is it using to interfere with my machine's network? What happens when an IP/ICMP packet arrives on the network? Where in the networking stack is the packet getting eaten? See also No internet connection with Cisco VPN Cisco VPN Client interrupts connectivity to my LDAP server Cisco VPN stops Windows 7 Browsing How can I prohibit the creation of a route in Windows XP upon connection to Cisco VPN? Rerouting local LAN and Internet traffic when in VPN VPN Client "Allow local LAN Access" Allow Local LAN Access for VPN Clients on the VPN 3000 Concentrator Configuration Example LAN access gone when I connect to VPN Windows XP Documentation: Route Edit: Things I've not yet tried: >route delete 10.0.* Update: Since Cisco has abandoned their old client, in favor of AnyConnect (HTTP SSL based VPN), this question, unsolved, can be left as a relic of history. Going forward, we can try to solve the same problem with their new client.

• How to reinstall OEM Windows 98 SE?

  - by Sammy

  I'm trying to install Windows 98 SE on an old PC and it's not going well. I run into this problem. Searching for Boot Record from Floppy..OK Starting Windows 98... TOSHIBA Enhanced-IDE CD/DVD-ROM Device Driver (ATAPI) Version 2.24 (C)Copyright Toshiba Corp. 1995-1999. All rights reserved. Device Name : TOSCD001 Number of units : 1 MSCDEX Version 2.25 Copyright (C) MIcrosoft Corp. 1986-1995. All rights reserved. Drive Z: = Driver TOSCD001 unit 0 TOSHIBA MACHINE Invalid drive specification Path not found - C:\TOOLS\CDROMDRV.SYS Invalid drive specification Invalid drive specification After that last line, it leaves me at a bitmap image displaying instructions to reboot with Ctrl+Alt+Del. It doesn't say why I have to reboot, and it doesn't state any error type, it just want's me to reboot for no apparent reason. After reboot, it just boots up from Floppy again and it cycles through the same thing all over again. The computer has been restored to original specification. Original system recovery "CD-ROM" discs are available and they are not scratched or anything, they are in very good condition. It's a set of 3 CDs, and the first disc labeled "1/3" should be the one holding the OEM version of Windows 98 SE. There is also a boot disk for Windows 98. I'm not sure what the other two discs are for. This computer came with three language support, so those could be holding different language versions or additional OEM discs. But I'm quite sure that the first disc holds the main operating system. BIOS has been set to optimized defaults. Boot priority is as follows; Floppy, IDE-0, CD-ROM. Under Standard CMOS settings, BIOS scans and autoconfigures both the hard drive and the CD/DVD drive. On POST it finds them both, and it finds the DOS bootdisk and starts preparing for installation, as you can see above. So what's this "invalid drive specification" about? Why isn't the installation starting? Updates Update 1 Booting from CD disc 2 In desperation I tried booting from the second CD. Boot order was; Floppy, CD-ROM, IDE-0. It boots normally from floppy disk, just like above, but then returns following. File not found - Z:\3LNGINST\TOOLS\PARTINFO.TXT I accidentally pressed some key on the keyboard, and before I knew it, the following screen showed up. Create Primary DOS Partition Current fixed disk drive: 1 Verifying drive integrity, 16% complete. After completion another screen showed up. Create Primary DOS Partition Current fixed disk drive: 1 Do you wish to use the maximum available size for a Primary DOS Partition and make the partition active (Y/N)?....................? [Y] Verifying drive integrity, 7% complete. I didn't choose Yes, it was set automatically. After completion the computer was automatically rebooted. Then I got a new screen. This is in Norwegian/Swedish/Finnish. Here's the message in Swedish. Hårddisken är inte klar för återställning av programvara. Installationsprogrammet måste skapa nya partitioner (C:, D:, ...). VARNING! ALLT INNEHÅLL PÅ HÅRDDISKEN KOMMER ATT RADERAS! Tryck på en tangent om du vill fortsätta (eller CTRL-C för att avbryta). Let me translate that. Hard drive is not ready for restoring the software. Setup program has to create new partitions (C:, D:, ...). WARNING! ALL CONTENTS ON THE HARD DRIVE WILL BE ERASED! Press any key to continue (or CTRL-C to cancel). I pressed Enter and it started formatting the hard drive. WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE c: WILL BE LOST! Proceed with Format (Y/N)?y Formatting 14,67.53M 1 percent completed. It automatically sets the "y" option and starts formatting. Rebooting with CD disc 1 After completing this operation it rebooted automatically. I inserted CD disc 1 and there was no issue with "invalid drive specification" anymore. Instead, a bitmap menu was displayed where it asked me to choose a language. And I thought I had it there for a while but it didn't work out. After choosing the language, another menu was displayed asking me to choose a type of recovery (restore pre-installed software OR restore hard drive partitions and pre-installed software). I opted for the second option. Then a data destruction warning showed up where I just pressed 1 to Continue. It did something and then just rebooted and the same formatting screen shows up as before. So something is not right. Am I doing it wrong? I seem to have come past the CD-ROM driver issue at least. But now I'm stuck with this problem... it seems to have something to do with the hard drive. Like... why is is it always trying to format it? Isn't it enough to format it once? By the way, it needs to be formatted as FAT32, right? Windows 98 doesn't support NTFS? I think FDISK should have taken care of this already. I know this is an old hard drive, but I connected to my main computer and it was able to read and write to it without a problem. It does have bad sectors though, but it's expected on an old hard drive like this. Any ideas?.. Update 2 I seem to be repeatedly getting stuck at the format screen where it asks to press any key to continue. So tried to cancel it this time with Ctrl+C. This leaves me at: A:\TOOLS> I can do DIR and CD and I tried to change to Z: drive. I tried running "setup" but there is no such thing.

• Why can't I play DVDs on Windows 8 Pro with Media Center Pack?

  - by ligos

  I have a laptop with Windows 8 Pro with Media Center (64 bit), but neither Media Player or Media Center can play DVDs. Have I done something wrong? Did the Feature Pack not install correctly? Should this work? Can I somehow uninstall and reinstall the Media Pack? Details So I upgraded by Windows 7 Home Premium laptop to Windows 8 Pro based on Microsoft's low pricing. I also grabbed my free upgrade to Media Pack and followed the instructions on that page to add my feature pack. Alas! I still cannot play DVDs via either Media Center or Player. Various Context Thinking I might need to re-install the pack, I found that I could no longer add any more feature packs (searching for add features settings only shows Turn Windows Features On and Off). Media Centre and Media Player are both enabled in Windows Features. I cannot see any way to remove or downgrade from the Media Pack, nor to add any more feature packs. I installed a codec pack (32bit) from Shark007, which has not allowed me to play DVDs (although did allow me to play various other media files). Media Player can play DTV recorded on another Windows 7 box, but Media Center cannot. VLC plays DVDs OK, but I'd prefer to figure out what the root cause of this problem is. There were no errors or other indications that the Media Pack failed to install; the installation itself was quite smooth. Although I have not checked my event log in detail. Before upgrading to Windows 7, I could play DVDs OK. Screenshots System Information, showing I have Windows 8 Pro with Media Center When playing a DVD, Media Player gives and error: The selected file has an extension that is not recognised by windows... When you click Yes, it fails saying: Windows Media Player cannot find the file... Media Center says: The file type is not recognisd and cannot be played, along with some codec related stuff. I can browse the files OK via My Computer on any video DVD.

• IRP_MJ_WRITE latency up to 15 seconds

  - by racitup

  We have written an application that performs small (22kB) writes to multiple files at once (one thread performing asynchronous queued writes to multiple locations on behalf of other threads) on the same local volume (RAID1). 99.9% of the writes are low-latency but occasionally (maybe every minute or two) we get one or two huge latency writes (I have seen 10 seconds and above) without any real explanation. Platform: Win2003 Server with NTFS. Monitoring: Sysinternals Process Monitor (see link below) and our own application logging. We have tried multiple things to try and solve this that have been gleaned from a few websites, e.g.: Making the first part of file names unique to aid 8.3 name generation Writing files to multiple directories Changing Intel Disk Write Caching Windows File/Printer Sharing Minimize memory used Balance Maximize data throughput for file sharing Maximize data throughput for network applications System-Advanced-Performance-Advanced NtfsDisableLastAccessUpdate - use fsutil behavior set disablelastaccess 1 disable 8.3 name generation - use "fsutil behavior set disable8dot3 1" + restart Enable a large size file system cache Disable paging of the kernel code IO Page Lock Limit Turn Off (or On) the Indexing Service But nothing seems to make much difference. There's a whole host of things we haven't tried yet but we wondered if anyone had come across the same problem, a reason and a solution (programmatic or not)? We can reproduce the problem using IOMeter and a simple setup: Start IOMeter and remove all but the first worker thread in 'Topology' using the disconnect button. Select the Worker thread and put a cross in the box next to the disk you want to use in the Disk Targets tab and put '2000000' in Maximum Disk Size (NOTE: must have at least 1GB free space; sector size is 512 bytes) Next create a new access specification and add it to the worker thread: Transfer Request Size = 22kB 100% Sequential Percent of Access Spec = 100% Percent Read/Write = 100% Write Change Results Display Update Frequency to 5 seconds, Test Setup Run Time to 20 seconds and both 'Number of Workers to Spawn Automatically' settings to zero. Select the Worker Thread in the Topology panel and hit the Duplicate Worker button 59 times to create 60 threads with identical settings. Hit the 'Go' button (green flag) and monitor the Results tab. The 'Maximum I/O Response Time (ms)' always hits at least 3500 on our machine. Our machine isn't exactly slow (Xeon 8 core rack server with 4GB and onboard RAID). I'd be interested to see what other people get. We have a feeling it might be something to do with the NTFS filesystem (ours is currently 75% full of fragmented files) and we are going to try a few things around this principle. But it is also related to disk performance since we don't see it on a RAMDisk and it's not as severe on a RAID10 array. Any help is much appreciated.

• Laptop LCD sometimes stops working on reboot. Please help.

  - by J Ringle

  I have a Gateway P-6831FX Laptop with Vista Ultimate. The Laptop LCD will sometimes not come on after I reboot the computer. I don't even close the lid and it happens. It isn't dim, it doesn't come on at all. No posting of CMOS (BIOS), nothing. Please note... this happens sometimes, not every time. Frustrating! When plugged into an external monitor, which works fine, Vista display properties can't even "sense" the laptop LCD. I try to enable the laptop LCD for dual display, turning on the laptop LCD, and it does nothing. It's like the laptop LCD is not even there. Manually taking a magnet in my hand to the laptop lid sensing switch (the sensor that turns off display/sleep mode when you close lid), sometimes causes the LCD backlight to "turn on" but not display any images. By "turn on" I mean I can see the screen backlight turn on to a 'dark gray' screen instead of pitch black. Subsequent reboot the laptop display is not working again! Here are the facts: Only happens at random and only after a reboot. Waking from Sleep mode isn't a problem. Pressing F4 function key for dual display does nothing when this happens. Closing lid doesn't seem to be related. (unless it is only after reboot.) using external magnet from laptop screen sensor sometimes triggers backlight to turn on but reboot back to square one with no LCD display. an external display always works fine. I have taken apart LCD, checked all wires and ribbons for loose connections or damage. I have replaced the Inverter. It doesn't seem to be heat related as I can put in sleep mode and resume fine when very hot. (external monitor works fine too). Sometimes the screen works fine as if there is not a problem at all. Even after a reboot... This is random. Any ideas out there? If it is a bad part... which one? The LCD seems to be fine. What are the odds of 2 bad inverters? The backlight is fine. The LCD wires/ribbons seem to be fine. I am at a loss. No warranty left and Gateway tech support is clueless. Thanks for any feedback that might help.

• OS X: Finder error -36 when using SMB shares on a Samba server bound to AD

  - by Frenchie

  We're looking at deploying SMB homes on Debian (5.0.3) for our mac clients rather than purchasing four new Xserves. We've got our test servers built and functioning properly. Windows clients behave perfectly, but we've run into an issue with OS X (10.6.x and 10.5.x). We're going this route instead of Windows file servers due to a whole bunch of other issues that arise when going that way. Specifically, when mounting a SMB share with unix extensions switched on and the remote server bound to AD, the finder cannot save files on the share, instead touching the file and then bombing out with a -36 IO error, folder creation is fine. Copying files in the terminal behaves fine and the problem seems to be limited to the finder. The issue arises (I think) as the remote UID/GID is passed across when using unix extensions. OS X uses its own winbind idmap (odsam) to work out the effective UID/GID from AD users and groups whilst we're using a rid map on the server. Consequently, there is a mismatch in ownership which the finder chooses to honour. How OS X appears to handle this is to use the remote uid and gid at the file permission level (see below) and then set an OS X acl granting the local uid/gid to have the appropriate permissions on the file. I think the finder touches the file (which the kernel allows because of the ACL) and then checks the filesystem perms and drops out with the IO error.

This works for most things but is causing a few apps that expect certain perms to break in subtle ways. Worst case scenario is that we'll continue running in this way but we would like to have the unix extensions on. Regards.

• openstack, bridging, netfilter and dnat

  - by Craig Sanders

  In a recent upgrade (from Openstack Diablo on Ubuntu Lucid to Openstack Essex on Ubuntu Precise), we found that DNS packets were frequently (almost always) dropped on the bridge interface (br100). For our compute-node hosts, that's a Mellanox MT26428 using the mlx4_en driver module. We've found two workarounds for this: Use an old lucid kernel (e.g. 2.6.32-41-generic). This causes other problems, in particular the lack of cgroups and the old version of the kvm and kvm_amd modules (we suspect the kvm module version is the source of a bug we're seeing where occasionally a VM will use 100% CPU). We've been running with this for the last few months, but can't stay here forever. With the newer Ubuntu Precise kernels (3.2.x), we've found that if we use sysctl to disable netfilter on bridge (see sysctl settings below) that DNS started working perfectly again. We thought this was the solution to our problem until we realised that turning off netfilter on the bridge interface will, of course, mean that the DNAT rule to redirect VM requests for the nova-api-metadata server (i.e. redirect packets destined for 169.254.169.254:80 to compute-node's-IP:8775) will be completely bypassed. Long-story short: with 3.x kernels, we can have reliable networking and broken metadata service or we can have broken networking and a metadata service that would work fine if there were any VMs to service. We haven't yet found a way to have both. Anyone seen this problem or anything like it before? got a fix? or a pointer in the right direction? Our suspicion is that it's specific to the Mellanox driver, but we're not sure of that (we've tried several different versions of the mlx4_en driver, starting with the version built-in to the 3.2.x kernels all the way up to the latest 1.5.8.3 driver from the mellanox web site. The mlx4_en driver in the 3.5.x kernel from Quantal doesn't work at all) BTW, our compute nodes have supermicro H8DGT motherboards with built-in mellanox NIC: 02:00.0 InfiniBand: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE] (rev b0) we're not using the other two NICs in the system, only the Mellanox and the IPMI card are connected. Bridge netfilter sysctl settings: net.bridge.bridge-nf-call-arptables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-ip6tables = 0 Since discovering this bridge-nf sysctl workaround, we've found a few pages on the net recommending exactly this (including Openstack's latest network troubleshooting page and a launchpad bug report that linked to this blog-post that has a great description of the problem and the solution)....it's easier to find stuff when you know what to search for :), but we haven't found anything on the DNAT issue that it causes.

• PSTN Trunk TDM400P Install on Asterisk / Trixbox

The FXO module is directly connected to our phone line from BT via a BT-RJ11 cable. I'm guessing I've missed a configuration step somewhere but no idea where, any help greatly appreciated.

• Apache taking up too much CPU

  - by andrewtweber

  I'm trying to manage a server on Amazon for a network of sites that receives about 100 million pageviews per month. Unfortunately, nobody out of my team of 5 developers has much server admin experience. Right now we have the MaxClients set to 1400. Currently our traffic is about average, and we have 1150 total Apache processes running, which use about 2% CPU each! Out of those 1150, 800 of them are currently sleeping, but still taking up CPU. I'm sure there are ways to optimize this. I have a few thoughts: It appears Apache is creating a new process for every single connection. Is this normal? Is there a way to more quickly kill the sleeping processes? Should we turn KeepAlive on? Each page loads about 15-20 medium-sized graphics and a lot of javascript/css. So, here's our Apache setup. We do plan on contracting a server admin asap, but I would really appreciate some advice until we can find someone. Timeout 25 KeepAlive Off MaxKeepAliveRequests 200 KeepAliveTimeout 5 <IfModule prefork.c> StartServers 100 MinSpareServers 20 MaxSpareServers 50 ServerLimit 1400 MaxClients 1400 MaxRequestsPerChild 5000 </IfModule> <IfModule worker.c> StartServers 4 MaxClients 400 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> Full top output: top - 23:44:36 up 1 day, 6:43, 4 users, load average: 379.14, 379.17, 377.22 Tasks: 1153 total, 379 running, 774 sleeping, 0 stopped, 0 zombie Cpu(s): 71.9%us, 26.2%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 1.9%si, 0.0%st Mem: 70343000k total, 23768448k used, 46574552k free, 527376k buffers Swap: 0k total, 0k used, 0k free, 10054596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1756 mysql 20 0 10.2g 1.8g 5256 S 19.8 2.7 904:41.13 mysqld 21515 apache 20 0 396m 18m 4512 R 2.1 0.0 0:34.42 httpd 21524 apache 20 0 396m 18m 4032 R 2.1 0.0 0:32.63 httpd 21544 apache 20 0 394m 16m 4084 R 2.1 0.0 0:36.38 httpd 21643 apache 20 0 396m 18m 4360 R 2.1 0.0 0:34.20 httpd 21817 apache 20 0 396m 17m 4064 R 2.1 0.0 0:38.22 httpd 22134 apache 20 0 395m 17m 4584 R 2.1 0.0 0:35.62 httpd 22211 apache 20 0 397m 18m 4104 R 2.1 0.0 0:29.91 httpd 22267 apache 20 0 396m 18m 4636 R 2.1 0.0 0:35.29 httpd 22334 apache 20 0 397m 18m 4096 R 2.1 0.0 0:34.86 httpd 22549 apache 20 0 395m 17m 4056 R 2.1 0.0 0:31.01 httpd 22612 apache 20 0 397m 19m 4152 R 2.1 0.0 0:34.34 httpd 22721 apache 20 0 396m 18m 4060 R 2.1 0.0 0:32.76 httpd 22932 apache 20 0 396m 17m 4020 R 2.1 0.0 0:37.34 httpd 22933 apache 20 0 396m 18m 4060 R 2.1 0.0 0:34.77 httpd 22949 apache 20 0 396m 18m 4060 R 2.1 0.0 0:34.61 httpd 22956 apache 20 0 402m 24m 4072 R 2.1 0.0 0:41.45 httpd

  How do I call the xrandr command? I want to rotate my screen 90 deg. clockwise.

• Benchmarking hosting providers IO with Bonnie

  - by Derek Organ

  Ok, because of a bunch of projects I'm working on I've access to dedicated Servers on a 3 hosting providers. As an experiment and for educational purposes I decided to see if I could benchmark how good the IO is with each. Bit of research lead me to Bonnie++ So I installed it on the server and ran this simple command /usr/sbin/bonnie -d /tmp/foo The 3 machines in different hosting providers are all dedicated machines, one is a VPS, other two are on some cloud platform e.g. VMWare / Xen using some kind of clustered SAN for storage This might be a naive thing to do but here are the results I found. HOST A Version 1.03c ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP xxxxxxxxxxxxxxxx 1G 45081 88 56244 14 19167 4 20965 40 67110 6 67.2 0 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP 16 15264 28 +++++ +++ +++++ +++ +++++ +++ +++++ +++ +++++ +++ xxxxxxxx,1G,45081,88,56244,14,19167,4,20965,40,67110,6,67.2,0,16,15264,28,+++++,+++,+++++,+++,+++++,+++,+++++,+++,+++++,+++ HOST B Version 1.03d ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP xxxxxxxxxxxx 4G 43070 91 64510 15 19092 0 29276 47 39169 0 448.2 0 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP 16 24799 52 +++++ +++ +++++ +++ 25443 54 +++++ +++ +++++ +++ xxxxxxx,4G,43070,91,64510,15,19092,0,29276,47,39169,0,448.2,0,16,24799,52,+++++,+++,+++++,+++,25443,54,+++++,+++,+++++,+++ HOST C Version 1.03c ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP xxxxxxxxxxxxx 1536M 15598 22 85698 13 258969 20 16194 22 723655 21 +++++ +++ ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP 16 14142 22 +++++ +++ 18621 22 13544 22 +++++ +++ 17363 21 xxxxxxxx,1536M,15598,22,85698,13,258969,20,16194,22,723655,21,+++++,+++,16,14142,22,+++++,+++,18621,22,13544,22,+++++,+++,17363,21 Ok, so first off what is the best way to read the figures and are there any issues with really comparing these numbers? Is this in any way a true representation of IO Speed? If not is there any way for me to test that? Note: these 3 machines are using either Ubuntu or Debian (I presume that doesn't really matter)

• Sending text messages from Raspberry Pi via email fails

  - by vgm64

  I'm using mailx on my raspberry pi to try to send text messages updates for event monitoring. My phone number: 9876543210 My phone's email-to-text gateway address: [email protected] I can 1) Send emails from my raspberry pi to various email addresses. mail -r [email protected] -s "My Subject" [email protected] < body.txt and off it goes and is successfully delivered. 2) Send emails from various email address (not on RPi) using mailx to the above phone-email address and have them delivered as text messages. However, when sending emails to [email protected] from the Raspberry Pi using mailx the emails seem to spiral into the void and are never heard of again (no errors, no undeliverable messages, nothing). Does anyone know what could be causing this to go awry? Something about the basic deployment of the mail server on the pi? EDIT Based on @kobaltz's suggestion, I used sendmail instead. This led to a hang, then an error that stated that I lacked a fully qualified domain name (FQDN). I then used this website's instructions to add a domain name to the RPi. To paraphrase: I have set the FQDN in /etc/hostname: my-host-name.my-domain.com and /etc/hosts: 127.0.0.1 localhost.localdomain localhost 192.168.0.5 my-host-name.my-domain.com my-host-name Then add to /etc/mail/sendmail.cf: MASQUERADE_AS(`my-domain.com') MASQUERADE_DOMAIN(`my-host-name.my-domain.com') FEATURE(`masquerade_entire_domain') FEATURE(`masquerade_envelope') I put this in /etc/mail/sendmail.cf, BEFORE the MAILER() lines, ran sendmailconfig, answered Yes to the questions about using the existing files, and restarted sendmail. Emails now have the proper domain name. Progress, however, I am now stuck at the following error: 354 Enter mail, end with "." on a line by itself >>> . 050 <[email protected]>... Connecting to mxx.cingularme.com. via esmtp... 050 421 Service not available 050 >>> QUIT 050 <[email protected]>...
