• Xen private networking between multiple hosts

  - by Joe

  I have two physical hosts running Xen 3.2, sharing storage via iSCSI. On these two hosts are a number of domUs and I'd like to network them in multiple private networks so they can only contact other domUs on their private network. My understanding of the xen documentation suggests it's possible to do this within one dom0 (ie create virtual networks between domUs), but I've found nothing explaining how this can be implemented across multiple dom0s on different hosts. The only thing that jumps to mind is manually creating iptable rules to route data to the other host, but this seems to lack elegance and could quickly grow cumbersome. Any suggestions? All advice is much appreciated!

• Running a command or script in terminal from anywhere by adding it to the PATH, what am I doing wrong?

  - by Joe

  On osx/linux I want to be able to run a command/script on the terminal from anywhere which links to a program. ie I want to be able to run: alloy that runs: /usr/local/share/npm/lib/node_modules/alloy/bin/alloy I'm guessing adding to .bashrc is the best way? I've tried running: export PATH="$PATH:/usr/local/share/npm/lib/node_modules/alloy/bin" and also: export PATH="$PATH:/usr/local/share/npm/lib/node_modules/alloy/bin/alloy" Then I started a new terminal window but the alloy command doesnt work. Am I missing something?

• How can I troubleshoot Virtualbox port forwarding from Windows guest to OSX host not working?

  - by joe larson

  There are a plethora of questions about virtual box port forwarding problems but none with my specific details. I have a Windows install living in Virtual Box, hosted within OSX. I've got several webservers running on localhost on different ports within the Windows install. I cannot for the life of me get port forwarding to work so I can access those webservers from OSX. My settings look like this (yes I have a NAT adapter): And in my vbox configuration file the relavent portion looks like this: <NAT> <DNS pass-domain="true" use-proxy="false" use-host-resolver="false"/> <Alias logging="false" proxy-only="false" use-same-ports="false"/> <Forwarding name="RLPWeb" proto="1" hostport="7084" guestip="127.0.0.1" guestport="7084"/> <Forwarding name="UtilWeb" proto="1" hostport="4040" guestip="127.0.0.1" guestport="4040"/> <Forwarding name="WCARLP" proto="1" hostport="8084" guestip="127.0.0.1" guestport="8084"/> <Forwarding name="WCAUtil" proto="1" hostport="4848" guestip="127.0.0.1" guestport="4848"/> </NAT> I've turned off the Windows firewall to ensure it is not interfering, and I am not running a firewall on OSX. Anyway, when I attempt to go to for example http://127.0.0.1:4040/ on any of my OSX browsers, it will eventually time out. The log file for this VM shows that it is correctly reading the settings and implying it's doing the right thing here: 00:00:08.286 NAT: set redirect TCP host port 4848 => guest port 4848 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 8084 => guest port 8084 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 4040 => guest port 4040 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 7084 => guest port 7084 @ 127.0.0.1 00:00:08.290 Changing the VM state from 'LOADING' to 'SUSPENDED'. 00:00:08.290 Changing the VM state from 'SUSPENDED' to 'RESUMING'. 00:00:08.290 Changing the VM state from 'RESUMING' to 'RUNNING'. 00:00:08.337 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=000000012017d000 w=1834 h=929 bpp=32 cbLine=0x1CA8, flags=0x1 00:00:09.139 AIOMgr: Host limits number of active IO requests to 16. Expect a performance impact. 00:00:13.454 NAT: DHCP offered IP address 10.0.2.15 I've tried setting the Host IP to 127.0.0.1, and I've tried setting Guest IP blank and also 10.0.2.15. None of these seem to help. What else can I look at to troubleshoot this issue? Details of setup: OSX 10.6.8 Windows 7 Professional 64bit VirtualBox 4.1.2

• How to remove Character Style in Word 2003

  - by joe

  I am copying text into a Word document that has its styles protected. Some of the text has a Character style applied to it that I would like to remove. I can change the style and it looks okay visually, but when you click inside the text itself you can see in the style menu that the Character style is still applied. I try to change the style using the style drop down but the Character style won't go away even if I change it to the Paragraph style. Does anyone know what I am talking about and/or have any techniques for removing Character styles? I am looking forward to your responses. Let me know if I need to clarify. Thanks! UPDATE: My issue is that the Paragraph style is changing correctly, but the Character style remains applied even though the text is displayed as if the style is not applied. See http://office.microsoft.com/en-us/word/HA011876141033.aspx if you are not sure what I meen by Character styles. There are four types of styles — paragraph, character, list, and table (list and table styles are new as of Word 2002). However, the majority of styles you'll use are paragraph styles.

• Disable user accounts after a certain time period

  - by Joe Taylor

  Is there a way to create a local user account on a Windows 7 Professional machine that stays active only for a certain length of time e.g 12 months? The reason for doing this is we loan out laptops for 12 months to students, however some are less than prompt at bringing them back, if they were locked out of the laptop this would force them to bring the machine back in if they hoped to continue using the laptop. Also a warning would be helpful, although I could do this with a scheduled task.

• How can I get VirtualBox to run at 1366x768?

  - by Joe White

  I'm trying to run Windows 8 in VirtualBox. My laptop's display is exactly 1366x768. Windows 8 disables some of its features if the resolution is less than 1366x768, so I need to run the guest OS fullscreen. The problem is, VirtualBox refuses to run the guest at 1366x768. When VirtualBox is "fullscreen", the guest is only 1360x768 -- six pixels too narrow. So there's a three-pixel black bar at the left and right sides of the display. This user had the same problem, but the accepted answer is "install the Guest Additions", which I've already done; that got me to 1360, but not to 1366. According to the VirtualBox ticket tracker, there used to be a bug where the guest's screen width would be rounded down to the nearest multiple of 8, but they claim to have fixed the bug in version 3.2.12. I'm using version 4.1.18 and seeing the same problem they claim to have fixed, so either they broke it again, they were wrong about ever having fixed it, or my problem is something else entirely. This answer suggested giving the VM 128MB of video memory, and claimed no problems getting 1366x768 afterward. When I created the VM, its display memory was already defaulted to 128 MB. I tried increasing it to 256MB, but with no effect: the guest is still six pixels too narrow. My host OS is Windows 7 64-bit, and I'm running VirtualBox 4.1.18. How can I get VirtualBox to run my guest OS fullscreen at my display's native resolution of 1366x768?

• Experiences with Autonomy IDOL

  - by Joe Doyle

  We're currently looking at implementing Autonomy IDOL in our environment. Does anyone have any recommendations or gotchas that we should be aware of? Are other companies using IDOL successfully? I'm curious to get some real-world impressions beyond the case studies we've been provided with.

• What can I do to prevent system power downs?

  - by Joe King

  Yesterday I was given my brother's old laptop - core i7, 2.67GHz, 8GB RAM, 128GB SSD, Win7 64 bit. It's a Sony Vaio Z11. Approx 18 months old. When running something computationally intensive, the fan starts up and after about 30 secs it just powers itself down with no warning. I guess it is overheating. There is nothing in the event logs to suggest what is causing it - the only thing I see is "the last system shutdown was unexpected" or something similar. This is a problem for me because I use a lot of number crunching apps, which pretty much makes it useless to me. I would like to know if there is anything I can do, other than the obvious things I've done already - open up and clean out dust, re-install the OS. According to my brother, this problem started about 6 months ago when it was already outside warranty. If it's just used for simple things - web browsing, word processing etc, the problem does not occur. Any ideas for what I can do to fix this ? Update: I found that the laptop has 2 hardware settings for graphics: Speed and Stamina - the Speed setting seems to use an nvidia GEforce GT 330M, while the Stamina setting uses an Intel chipset. With the setting on Speed, I can hear the fan the whole time, and the system powers down after a short while (5-10 mins) even just doing basic tasks (browsing this site for example), but doesn't shut down if I just leave it switched on. In this mode it also sometimes just freezes the screen and I have to power off myself. However on Stamina setting it only powers down when doing number crunching and never freezes the screen.

• Create "raw disk file" from WIM file

  - by Joe Baltimore

  First timer here. I've searched around here, but haven't found a question like the one I have. Apologies if I missed it. The challenge at hand: produce a "raw disk image file" from a given WIM file. What I am pursuing so far is to use imagex.exe with the "/apply" operation to take the WIM and lay it down in a directory on a server. That seems to produce all the necessary "stuff" I need in that directory. How would I take that content and produce a "raw disk image file"? I'm told the definition of "raw disk image file" is a block-by-block copy of the disk image, which I hope is the output of the "imagex.exe /apply" command I use currently, but stored in a single file I can hand back to another system in our solution. imagex.exe /apply image.wim 1 R:\WimImagePoint I would like to take the contents of R:\WimImagePoint and produce the elusive (to me) "raw disk image file". ISO is not what they want, nor is anything requiring winPE. Any pointers? External utilities' references are welcome. Would like to avoid unmanaged code solutions as much as possible, but will entertain them if that's the only route. Also, I am not married to the idea of imagex /apply as the starting point, it's just the comfort zone so far.

• Moving the OS X swap file to a faster drive

  - by Milky Joe

  I have a new Mac Mini that's running the latest version of Snow Leopard. The internal drive is a bit of a slouch. I'd like to move the swap file (or whatever it's called is OS X) to my faster external drive (Firewire 800, permanently connected). Is this possible? I've read that the old solutions aren't working in 10.6. My Mac has 2GB of RAM, so the swap file is used quite a bit when I'm doing intensive work (Photoshop etc).

• Blue screen - BCCode: 7F

  - by Joe

  I've recently bought a refurbished Toshiba Satellite A660 11M and I get the blue screen of death appearing fairly frequently now, and I can't seem to work out why or how to prevent/cure it. Firstly I thought it was due to Zone Alarm from what I read on the net, but then I thought it was a memory issue after it crashed whilst I was running Memtest. But after I ran Memtest a second time, it completed without any errors... Here are my computer specs - Toshiba Satellite A660 11M 500 GB hard disk 4 GB RAM Windows 7 Premium Nvidia GeForce GT 330M and here is more info regarding the crashes I keep getting - Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7600.2.0.0.768.3 Locale ID: 2057 Additional information about the problem: BCCode: 7f BCP1: 0000000000000008 BCP2: 0000000080050033 BCP3: 00000000000006F8 BCP4: FFFFF80003040EC0 OS Version: 6_1_7600 Service Pack: 0_0 Product: 768_1

• Change Envelope From to match From header in Postfix

  - by lid

  I am using Postfix as a gateway for my domain and need it to change or rewrite the Envelope From address to match the From header. For example, the From: header is "[email protected]" and the Envelope From is "[email protected]". I want Postfix to make the Envelope From "[email protected]" before relaying it on. I took a look at the Postfix Address Rewriting document but couldn't find anything that matched my use case. (In case you're curious why I need to do this: Gmail uses the same Envelope From when sending from a particular account, no matter which From: address you choose to use. I would prefer not to disclose the account being used to send the email. Also, it messes with SPF/DMARC domain alignment - see 4.2.2 of the DMARC draft spec.)

• Can storage-spaces drives be moved to a replacement server when there is a failure

  - by Joe C

  I have tried to search here and Google, but cannot find a case explaining this. Storage spaces is similar to software raid. If the server fails due to motherboard or some other issue, can the drives that comprise that storage spaces config be moved to another win2k12 server without restoring from backup? This can be done in linux software raid. If so, does the storage space config have to be re-created prior to the move, or do the drives hold the config so they are essentially plug and play? Thanks.

• Connecting to my home router web interface from work

  - by Joe

  Hi, I'm trying to connect to my home router web interface from work. I use dyndns, because I don't have a static IP at home, and it works perfectly from any other place except my workplace (update: I made a mistake, see edit below). When trying to access the web interface from work I get a "500 Server Error" with the code: SERVER_RESPONSE_RESET. I'm not trying to use any protocols such as remote desktop, I'm only trying to access the web interface. I can access any other web page from my workplace with no problems, and I think my router web interface is like any other web page, isn't it? I thought maybe my work place proxy blocks addresses of services like dyndns, so I also applied another trick. Since I have a web page on my own domain (say www.mydomain.com) which I can access from work, I tried adding a CNAME to my domain which is linked to the dyndns address (router.mydomain.com). This way if anyone enters the address router.mydomain.com from anywhere, they reach my home router web interface, and there's no way of knowing it's a dyndns address (or is there?). However, it still doesn't work from my workplace (I get the same error message). Any ides? Edit: I'm sorry to say I made a mistake earlier. I used to be able to access my home router web interface from my old workplace, and I thought it was still possible since I don't recall making any configuration changes. However, after reading the replies, I went over to my old workplace and checked, and it doesn't work from there either. I'm very sorry for giving out wrong and misleading information about my problem. So to summarize: my problem is that I can't access my home router web interface from anywhere.

• In search of a good audio player for Ubuntu 9.10

  - by Joe Casadonte

  If this should be marked Community Wiki, please let me know. I'm switching from XP to Ubuntu, and I have been very disappointed with the selection of media players available. I'm primarily interested in an audio player, but integrated video and library management is OK, too. My criteria: Must be able to play audio CDs (I'm shocked how many apps this does away with, right away) Must be able to play MP3 & WAV; OGG, SHN, FLAC are all bonuses Repeat and Shuffle modes are a must FreeDB / GraceNote through a proxy is a must (if it can read a PAC file, that would be awesome) It needs to be really small, e.g. skinnable or an applet Ability to execute a playlist is a plus Gapless MP3 playback a plus I'm running Gnome, but I'm not totally adverse to a KDE app. Command-line only is also a viable option. Some that I've tried: RhythmBox - probably the best of the lot that I've tried; I don't like its mini mode (doesn't show the song being played) and I can't figure out how to get it to hit FreeDB/GraceNote through a proxy Songbird - can't play CDs, playlist management is atrocious Banshee Jajuk Maybe a couple of more. Thanks! UPDATE I tried out VLC, Amarok and Songbord (again). VLC I eventually got to work (I had some kind of bad configuration). It seemed way more involved than I was looking for out of a music player, and in general more geared to video than audio. I couldn't fathom its library management, which I think it has; maybe it doesn't, and that's why I couldn't figure it out. Amaork looked very promising but the library management was not to my liking, and the way it handled a playlist with both MP3 and WAV is inexplicable at best. I did like some aspects of the UI, but not enough to keep it. Songbird is very finicky, but I like the library management. Sort of. It kept telling me my Watch folder was invalid, even thought it clearly was accessible. Playlist management is bizarre, and the message that it was deleting source files whenever I deleted a playlist had me too worried to keep using it. Had it been able to play CDs, maybe I would have persevered. Audacious, while a bit odd at times, does seem to do what I want. If it had a library manager, I wouldn't have bothered trying any of the others. Thanks for the help, everyone!

• XP User account cannot write to USB

  - by Quick Joe Smith

  Is there a local security policy setting or somesuch to allow limited user accounts to modify the contents of USB drives? Currently I get an "Access denied" error, further saying "Make sure the disk is not full or write-protected and that the file is not currently in use." The Administrator account has no such obstacles. Update: The problem is at least solvable by altering NTFS permissions (granting Full Control to Users), and therefore I'm losing hope that there is a more global solution.

• Un-table a cell range in Excel 2007

  - by Joe

  In Excel 2007, if you highlight a block of cells and then "Format as Table", it doesn't just apply colors and formatting, it somehow marks those cells as being a table. Now I want to get rid of the table, but keep all the cells (i.e. keep the data). So I tried clearing the table style and formatting, but Excel still recognizes those cells as being a table. I can tell because: When I select a cell that was in the table, Excel still displays the "Table Tools / Design" tab I cannot merge cells that were in the table <- this is what's annoying me So, how do I un-table those cells? I want to keep all the cell data and formatting, but have Excel not recognize them as a table.

• Update a bootable OS X drive clone with rsync?

  - by Joe

  The question: is it possible to keep a boot-able backup drive clone of OS X updated with rsync? If rsync is not a viable option are there alternatives? The Setup: My situation is as shown above. One internal Samsung 840 SSD [120g] in use as my OS X 10.8 boot disk on a recent model Mac Mini. I have successfully cloned that drive with disk utility to a 125g partition of another HDD in an external USB 3 enclosure and at that point I am able to boot to it. The Goal: As my last system went out in a fiery blaze taking much valuable data with it, I have a new respect for a proper backup solution and really want to do this right. My goal is to achieve an automated differential backup/update from Disk A to Disk B while most importantly maintaining boot-ability on the external drive. And I would prefer to do this differentially to minimize stress on the drives. Hence rsync was the first thing to come to mind. What I have tried: following along with Jamie Zawinski's differential mac bootable backup solution running this manually initially worked - i tested it with only very miniscule file change and everything was fine / external booted and all. now after subsequent passes rsync fails throwing errors particularly relating to updating 'boot.efi' (not at the machine currently I will update the precise log message once I return home) is this a drive partition size issue? does rsync require more space? if it cant be done, are there any alternatives? i've heard whispers of dd

• Server 2003 RAS Server Utilising High WAN Traffic

  - by Joe Sergeant

  We have Routing and Remote Access configured on Server 2003 (also our primary domain controller), allowing users to connect in remotely to access files, email, etc. With one user, the RAS Server is constantly sending data to that user's remote computer. From 9am this morning it has transferred almost 800MB. The user isn't transferring any files remotely, certainly not enough to total 800MB anyway. None of the other remote users have had this issue. We have ensured that the user in question has "Use default gateway on remote network" disabled for both IPv4 and IPv6 and we are fairly confident that Offline Files isn't trying to synchronise with the server remotely, too. My question is two-fold. Firstly, has anyone had a similar experience? Secondly, what would be the best software to discover exactly what data is being sent to the remote user?

• Five stars of open data - example and review

  - by Joe

  (there may be a more suited SE site for this question so feel free to shift) I have some data I'd like to make open to the public - It's synatesis of some related data retrived from freedom of infomation requests over the last year. The data itself is at http://www.cs.rhul.ac.uk/home/joseph/domesday/Domesday-Scotland.csv or for fans of Excel, at http://www.cs.rhul.ac.uk/home/joseph/domesday/Domesday-Scotland.xlsx . It's no more than a table with about five columns. I'd like to make this properly open data, so I was looking at the 5 star deployment scheme for Open Data. Much of which is fine but I'm confused towards the end and I could do with an explenation from people who know the answers. So to get achieve the star levels I need: "make your stuff available on the Web (whatever format) under an open license" trival - all I have to do is put the notes up on the page that will give the provance of the data. "make it available as structured data (e.g., Excel instead of image scan of a table)"… done… "use non-proprietary formats (e.g., CSV instead of Excel)" - done… "use URIs to identify things, so that people can point at your stuff" - this is where I start to get a bit hazy - does this mean there should be an URI for every line in the table? "link your data to other data to provide context" - this isn't massively clear to me - does this mean to give the provence of the data? One column of the data I've put out is a link to where the data came from - is that the sort of thing we're looking at? Any and all information and answers welcome… EDIT - or if anyone wants to recommend a place SE or other place to ask the question - that would be cool...

• Auto switching between wired and wireless connections

  - by Joe

  How about this situation. Our business deals a lot with medical information. And some of our clients have demands based off HIPPA, etc. There is one now where they do not want an employee to have both wired and wireless on at same time. If the wireless is on the wired needs to be turned off automatically and vice versa. However, this can not be up to the end user to manage! I have looked for third party applications and only have found http://www.wirelessautoswitch.com Does anyone know of anything else that is out there? Or possible something that can be done via group policy, etc.?

• Blank list of windows services

  - by Joe

  Recently when I open windows services (always as administrator) I get a blank list of services: When I try and click on one of the empty lines I get this "Script Error" message: This happens over and over again, after several times I restarted my computer. I can't pinpoint exactly when this started happening or if I made any specific changes to my computer at that time. Someone told my to try running scf /scannow as administrator, but when I try to do that the scan stops at 34% and I get the message: "Windows Resource Protection could not perform the requested operation." I am running Windows 7 Enterprise 64 bit, and I would really like to avoid reinstalling windows. Does anyone know how to fix this? Edit - Here is another attempt I made and some more information that might help: Following WhoIsRich's suggestion, I tried the command sfc /scannow /offbootdir=c:\ /offwindir=c:\windows. This gave the error message "The arguments passed to sfc are invalid. The offline windows directory specified points to the online system", and then I realized this command is meant to be run after booting from another system. Since I don't have my windows installation disk right now, I used my own system to create a recovery disk, and then restarted my computer and used the recovery disk to boot. I then ran the above command, and I got the following message: "Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log". I then restarted my computer and let it boot up normally. The problem with windows services persists, and the CBS.log file is a long log file with many entries, and I don't know if there is useful information in it, and if there is, how to find it.
