• Automatic o/s reset on a dedicated internet browsing Windows 7 pc.

  - by camelCase

  I have just purchased a new Acer Revo nettop PC for dedicated internet browsing. It will be the only pc on a home network. My original plan was to install one virtual PC for family browsing, another for remote web based server administration and ban browser use from the host Windows 7 o/s. The idea was that I could recover to a fresh VHD image once a week to eliminate any build up of malware inside the browser VMs. However now I am looking for alternative solutions since the Intel Atom cpu does not have hardware VT support which Windows Virtual PC requires. Would it be possible to engineer some type of routine overnight host o/s wipe and recovery? I guess cyber cafes do something like this? The only user data that would need to be retained across a recovery would be browser bookmarks but these could be exported to remote service. Edit 1: I am thinking the o/s reset could be done via some disk image recovery process. Edit 2: Just had a brainwave. Routine browsing could be done via the new Google Chrome O/S. I have just seen a video of the Google Chrome o/s booting off a usb pen drive in seconds.

• Encrypted folders and files stay encrypted when copied

  - by user66126

  Hi all, I just tried out Windows 7 feature to encrypt a folder. I found that when I access the encrypted folder from another computer (the parent folder of the encrypted folder is shared) I can see the files there but I could not open it (which is good). But when I copy the file to another folder outside the encrypted folder (regardless it is on the same remote computer or to the computer from where I am accessing the files) then I can open the file without any problem. This might be how it works ... but that's not what I need. My question is: Can I encrypt a folder (and all files inside), access those files (create, edit) seamlessly while I am logged in normally to the computer ... but make the files stays encrypted when they were copied to another directory outside the encrypted folder? Regardless they were copied to the same computer or another computer or uploaded to a remote server. If this is not a feature that Windows natively support, is there third party software that does that? Thank you.

• Can't connect to Server Manager from Windows 7

  - by SAdmin317

  I have a Windows 7 Pro 64bit with SP1 desktop that has RSAT tools installed. I opened Server Manager and can't connect to the server (Server 2008 R2 core). I followed the guide to enable everything on the server, added a registry key to enable read-only on the device manager as well. On the Windows 7 PC I turned on winrm, did the quick config, and added the server IP and name as trusted hosts. I still get an error when connecting. "Connecting to the remote server failed with the following error message: The WinRM client cannot process the requests. If the authentication scheme is different from Kerberos, or if the client computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHosts configuration setting...." I also added the name of the server to the windows 7 /etc/hosts file. Ping the server name translates to the IP of the server. Also opened up the firewall for "Remote Volume Management" Both machines are on the same Workgroup, using the same Administrator account, with the same password. Any help appreciated.

• Windows 7 caches FTP credentials?

  - by Martin Booka Weser

  On my remote maschine i have an iis 7.5 (win server 2008) and set up an ftp site with iis manager authentication. I then did active directory user isolation and isolated my users to physical folders according to their names. So far, so good. I can access with ftp cliens from everywhere with different test accounts that i previously set up in the iis manager auth. Every user connects to its own folder. When i now tested with windows 7 as a client i did the following. Explorer - computer - right click - add network address - the ip of my remote maschine - user1 - password1 Perfect - it works. I now want to connect with user2. So I deleted this network address and set up a new connection, but with user2 (or even anonymous) instead. Now the strange thing: Windows doesn't even ask me for a password again. It just connects me to the folder of the user1. I already disabled ftp caching in the IIS and i disabled the user1 account in IIS manager authentication! Still, if i set up a network connection with this windows 7 it connects to the folder user1 . No matter which username i use (anonymous, administrator, user2,...). And if i connect with other ftp clients or other computers it all works perfectly. So I assume that this one windows somehow caches the credentials... But then, why does the IIS still accepts this credentials even if i disabled this user1 account??? Thanks.

• Can't reliably ping 6224 router from directly-attached system

  - by David Mackintosh

  OK, here's my situation. This is on the internet. The 6224 is the router in this picture and physically resides in Kanata. Both VLAN 1697 and 3994 are provided by an internet service provider. These VLANs are provided through a single 1Gb ethernet wire. The Kanata hosts are directly attached to the 6224; the other two sites are remote. VLAN 3994 is a single IP address space, so theoretically it shouldn't matter physically where the hosts on that subnet are. Here's the problem. I have a monitoring system which is connected further into the internet, so probes from the monitor would come in to this diagram on the 1697 VLAN. When I ping hosts at Albert or Bells Corners from the internet, there is 0 loss. The connection looks perfect. When I ping hosts at Kanata, I lose anywhere from 10 to 40% of the pings. The loss is not predictable, but: when I do lose them, I always lose at least 3, usually 4, rarely more, pings in a bunch. I have attached a monitor directly to the 6224 in Kanata on 3994.. When the monitor pings the 6224 routing interface, I see exactly the same loss pattern -- but NOT at the same time as the loss from the remote system. Ping time is around 1ms. When the monitor pings another system directly attached to the 6224, there is 0 loss. Ping time is about 0.1ms, one-tenth of the time to ping the router. Anyone know what is going on here?

• What can I do with a home server?

  - by Joel Coehoorn

  I have an old 700 Mhz Pentium III at home running Windows 2000 Server, with a home router set up to pass incoming requests to it and a DynDNS account set up so it's easy to find. Right now I'm using it for a number of things: Shared folders + backup inside the home network Shared Printer inside the home network Domain Controller, just because I feel like it and because it's useful to me as practice to keep those "enterprise" administration skills. Web Server FTP remote access for my files. I abandoned this for security reasons, but it's still worth leaving visible. Remote Desktop in to the home network (thinking about adding VPN service) SVN repository MySQL - Will be moving to SQL Server 2008 Standard soon. After I upgrade my wife's laptop from home to pro later this year it will also become a domain controller It's the only place I still have access to Internet Explorer 6 any more without setting up a new virtual machine, so I use it for testing code with that browser. The question is: What else could I be doing with this machine? Update Additional ideas based on the suggestions: Media Server/DVR Build server PBX SSH Proxy Server Continuous Integration Server Personal OpenID Provider Update2 Just a note that this server was recently upgraded to an Atom330 with 2 GB ram and bigger hard drive. For all that's slow for a "modern" cpu, it should still be much faster than the old Pentium III and the expected power savings should make the upgrade essentially free over the course of the next year or two. Also, it's now running Windows Server 2008.

• Connection between Asp.Net and Oracle 10g Express Edition

  - by l3gion

  Hello, I'm struggling to find a way to connect my Asp .Net + C# application with my Oracle 10g Express Edition. Here's my scenario, I'm at Mac OS and I have 2 Virtual machines, one for Win 7 (VS 2010 app) and another with a Parallels Virtual Appliance with Oracle 10g Express Edition 1.1. Which provider (Oledb, ODP.NET, etc..) should I use? How to make the connection to the server in C#? Right now I have this: <appSettings> <add key="conn" value="Data Source=10.211.55.11;Persist Security Info=True;User ID=l3gion;Password=l3gion;" /> </appSettings> And at the .cs file: SqlCommand cmd = new SqlCommand("insert_thing", new SqlConnection(ConfigurationManager.AppSettings["conn"])); cmd.CommandType = CommandType.StoredProcedure; *insert_thing is a stored procedure Using this I got this error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I've searched for some possible solutions. Tried some, including: firewall disabled, allow remote connection at oracle express edition using this cmd line ("EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);").. The error persists. Can anyone guide me into the right direction? I'm a newbie with this type of things. Thank you for your patience. regards

• iis not listening on port 80

  - by Holian

  Hello, We have server 2003 and ISA 2004 with IIS 6 on same machnie. Everything worked well till yesterday, when we try to make some new rule in ISA..but this is a long story... Unfortunatelly something happend with our intranet site. Our site is on the port 80, but if we try to open on this client machines then we got and error page (which error page is our provider): 403-forbidden; Remote host not listening, the remote host is not prepared to acceppt the connection request. On the server i can open the site with port 80. If i change the port number in the iis and try to open the site with the port, then works well. I try to shut down IIS and start apache with a simple page. On the server works well but in clients the problem is the same, so i think this is not an IIS related problem. In the ISA we have a web pub rule, with port 80, no auth. Im pulling out my hair, please help.

• How do I get started with the M-Project is a Mobile HTML5 JavaScript Framework on Windows?

  - by Bruce Whealton

  This website for this great tool, call the M-Project says that I will need to add a doskey like this: doskey espresso=node C:\Path\To\Espresso\bin\espresso.js $1 $2 $3 $4 (It is a tool for creating Native mobile apps with the Phonegap/Cordova library, and it seems to be something that would be very helpful in this process). If I enter that at a command prompt in Windows 7 or 8, it's not going to stick around or persist. Is it an Environment Variable? Then it says at this page: http://www.the-m-project.org/ that it will work with Windows with some additional tools installed. The next line says that Node.js is needed, so I don't know if that is the additional tools mentioned above. Also, in an old discussion I read that one could just install cygwin. What would that do? It doesn't actually install any of the Linux distributions. I did install Ubuntu 12.04 server with VirtualBox because I thought it would be good to learn more about using Linux as I manage websites that are on a dedicated host. Anyway, the suggestion to install cygwin did not go into any details... I guess it would allow one to create a bash profile?? which would only work in a cygwin Command Line Window. Is that right? Isn't there a similar file that one could use in Windows or an Environment Variable that one could set to be able to achieve the same result? Thanks, Bruce

• How to setup the Mac OS X Terminal so it's *just peachy*?

  - by kch

  Hi all, My Terminal is awesome, has every detail just right (for me anyway), and now I'm setting up a few new macs around here and I have no idea whatsoever how to get their terminals to a pretty state. My user account is rather old, has been migrated over many OS X releases and machines, so my Terminal setup has grown rather organically over the years. What I need is a recipe to start from scratch, so 1) I know what I've done, and 2) I can reproduce it anywhere. Things I'm looking for: Full UTF8 support. Setting LC_*, displaying characters correctly, accepting input… I hear this got much easier in 10.5, maybe it all works out of the box now? Setup of OS X-style keyboard text navigation (option-arrows, etc) How you particularly handle meta-key support? (other than ESC'ing your way around) Other things to help our n00bs get around in the shell, such as: List of useful default key bindings (^A, ^D, etc…) Mac-specific .profile, .inputrc goodness Mac-specific tools such as pbpaste & pbcopy, Open Terminal Here, etc If at all possible, a list of files to copy over to another machine that encompasses all the changes made to tune the Terminal. (dotrc files, plists, etc) And, well, anything else really. Just keep the scope on the Mac OS X Terminal application, rather than general unix setup and tools. I think a collection of incomplete answers would be a good start. Post one or two things you remember having done, we'll vote them up, and after a few days I'll try to compile it all into a summary answer.

• RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

  - by Ed

  I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

• Is it possible to use rsync over sftp (without an ssh shell) ?

  - by Tom Feiner

  Rsync over ssh, works great every time. However, trying to rsync to a host which allows only sftp logins, but not ssh logins, provides the following error: rsync -av /source ssh user@remotehost:/target/ protocol version mismatch -- is your shell clean? (see the rsync man page for an explanation) rsync error: protocol incompatibility (code 2) at compat.c(171) [sender=3.0.6] Here's the relevant section from the rsync man page: This message is usually caused by your startup scripts or remote shell facility producing unwanted garbage on the stream that rsync is using for its transport. The way to diagnose this problem is to run your remote shell like this: ssh remotehost /bin/true > out.dat then look at out.dat. If everything is working correctly then out.dat should be a zero length file. If you are getting the above error from rsync then you will probably find that out.dat contains some text or data. Look at the contents and try to work out what is producing it. The most com- mon cause is incorrectly configured shell startup scripts (such as .cshrc or .profile) that contain output statements for non-interactive logins. Trying this on my system produced the following in out.dat: ssh-dummy-shell: Command not allowed. As I thought, the host is not allowing ssh logins. The following link shows that it is possible to accomplish this task using fuse with sshfs - however it is extremely slow, and not fit for production use. Is there any chance of getting rsync sftp to work?

• Why is ssh agent forwarding not working?

  - by J. Pablo Fernández

  In my own computer, running MacOSX, I have this in ~/.ssh/config Host * ForwardAgent yes Host b1 ForwardAgent yes b1 is a virtual machine running Ubuntu 12.04. I ssh to it like this: ssh pupeno@b1 and I get logged in without being asked for a password because I already copied my public key.

• Imac g5 with no OS nor CD drive

  - by sinekonata

  What I want: Ubuntu on a g5 Imac. What I have: An empty PC (Intel g5 17" Imac) with broken CD drive. Its model is A1173. This PC with Ubuntu 12.04 and an old Vista partition. a usb flash drive. Problems: No CD means the only boot Drive I could use is USB. There are no BIOS on Macs so I can't set boot settings or even see if it detects my USB drive. When I start the machine and press ALT the first and only thing I see is an old corrupted winXP partition and not a single option or additional information. So assuming blindly that the Mac hardware/firmware works normally, I don't have any Mac OS to use any of the tools that I found on different tutorials for building a bootable .img drive for macs. I can't find much software on Linux/Windows to substitute to those tools, for example among others converting an .iso file (win/linux) to .img (mac I guess). Which makes me think that the scenario where someone like me has Mac hardware but no Mac OS is extremely rare. So other than finding someone that has a Mac I have no solution. So I ask what would you do? the only thing is it should not involve any money (I know mac soft is rarely free) which also excludes getting any MacOS unless I can use a free macos.img for VM or restore the original Mac for free. Thank you

• Disk doesn't contain a valid partition table

• Web based KVM management for Ubuntu

  - by Tim

  We've got a single Ubuntu 9.10 root server on which we want to run multiple KVM virtual machines. To administer these virtual machines I'd like a web based KVM management tool, but I don't know which one to choose from the list of tools mentioned on linux-kvm.org. I've used virsh & virt-manager on my desktop, but would like a web interface for the server. I tested ConVirt on my desktop, but it failed to pickup KVM machines from virsh / virt-manager, and I could not get KVM virtual machine import to work (only Xen). oVirt looks good, but I can't find out if and how I can install it on Ubuntu 9.10.. (And I'd really rather not waste another few days on testing stuff that might not work in the end.) Can anyone recommend any good web based KVM management tools that are easy to install on Ubuntu 9.10? I'm looking for something that will also allow me to run other services like apache and postgresql besides hosting virtual machines, so preferably fairly lightweight & no dedicated OS installs. We don't need any professional clustering / migration or anything, just something that will let us create, start, inspect, administer & stop virtual machines from a web page. Best regards, Tim Update: Anyone have any suggestions? It's awfully quiet here..

• Password-less login into localhost

• virtualized windows 2003 domain with CentOS 5.3 and poor connectivity

  - by Chris Gow

  I have a test lab set up running a virtualized windows 2003 domain on a CentOS 5.3(xen) host and am experiencing connectivity problems with guests running on other hosts that are part of the same domain. Here's the setup: On Computer A I have CentOS 5.3 running as the host and have virtualized windows 2003 servers for a primary domain controller, a backup domain controller and an exchange server. The primary domain controller also acts as a WINS and dns server. The windows domain appears on a separate subnet from my company's corporate network. Connectivity to any of the virtualized guests on Computer A is fine (remote desktop, ping, what have you). I have another host computer (Computer B) that also has a virtualized Windows 2003 server guest that is part of the same domain. However, connectivity to that guest is flaky at best. I continuously get at least 60% packet loss when I try to ping the guest, and due to that flakiness I can not access any of the services that it runs (remote desktop, web). Now here's the interesting part. It seems to affect only machines running on a different computer than the domain controller that are in the same domain. On Computer B there is another Windows 2003 guest that is not part of the test domain and is on my corporate network. There's no connectivity issues with that guest machine. The problem does not seem to be specific to Computer B either. I created a test VM on my local computer within the test domain and it exhibits the same behaviour as the guest in Computer B. A couple of items to note: - Host OS on both Computer A and B are the same CentOS 5.3 64 bit - Guest OS is Windows 2003 64 bit and 32 bit (the guest on Computer B is 32 bit) - Guest OSes are all up to date (as of Monday) - Host OS on Computer A was upgraded from CentOS 5.2 to 5.3 Update: Sorry I did not follow up with the comments from below. Computer A and B have been moved to their own dedicated switch and the problem has gone away. I'm not sure what the underlying problem(s) were though

• Ubuntu odd mouse and keyboard behavior when window gains inner focus

  - by Scott

  This morning on my Ubuntu 10.10 system when I open a window - for example, system-preferences-about me, if I click in to a field such as "work email", I can no longer close the window with the mouse! Clicking the X on the window will not work. Also, I loose the ability to click on anything else - clicking on the desktop, icons, menus, workspaces, etc. do not work. Even the effect when you hover over a folder on the desktop and that folder highlights - that stops until the window is closed. If I open this same screen but do not click in to a field, everything is fine - I can close the window with the X and everything else works fine. Same thing happens with several other windows I tried. Even calculator - I can open it, everything is fine until I click on a button in the calculator - then no ability to click on anything else. Have to Alt-F4 to close the window. The system is only about a week old from a fresh install (64 bit ubuntu - quad core amd machine). I uninstalled wine, turned off remote desktop/disabled in startup, also in startup disabled visual assistance, bluetooth, dropbox, klipper. Reboot, no difference. The only other thing non-standard I see in startup is nvidia. Using a logitec usb mouse, saitek usb keyboard. Was working fine yesterday. I can not think of anything I did / installed yesterday. I switched themse, then went to update manager and saw two x server / x org related updates and installed them, reboot and NOW IT IS FINE! However, then I re-enabled dropbox, klipper and remote desktop rebooted and the problem is back. Again I disabled and rebooted. Problem is still there!! So somehow I fixed it at least for a few minutes, but now it is back and I am out of ideas.

• SSH does not allow the use of a key with group readable permissions

  - by scjr

  I have a development git server that deploys to a live server when the live branch is pushed to. Every user has their own login and therefore the post-receive hook which does the live deployment is run under their own user. Because I don't want to have to maintain the users public keys as authorized keys on the remote live server I have made up a set of keys that 'belong's to the git system to add to remote live servers (In the post-receive hook I am using $GIT_SSH to set the private key with the -i option). My problem is that because of all the users might want to deploy to live, the git system's private key has to be at least group readable and SSH really doesn't like this. Here's a sample of the error: XXXX@XXXX /srv/git/identity % ssh -i id_rsa XXXXX@XXXXX @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0640 for 'id_rsa' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: id_rsa I've looked around expecting to find something in the way of forcing ssh to just go through with the connection but I've found nothing but people blindly saying that you just shouldn't allow access to anything but a single user.

• Port mirroring on multiple switches

  - by Matt

  So here is the deal, I have a server on switch A where port 3 is monitoring traffic for most of the ports on switch A. However I have other users on switch B that needs to have port 3 on switch A monitor as well. Is this possible? I have been reading about rspan but doesnt seem to work. Switch A: monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 (this works great for switch A, I need a solution to get switch B to also have some ports sent to port 3 on switch A for monitoring.) Onxx, All the traffic on switch A is fine, there will be about 10-15 ports on switch B that I need to send to fa0/3 on switch A as the destination. I have the switches connected with a ethernet cable with a trunk port on both switches on port 48 on switch B and A and port 47 on A connects to our sonicwall. So I am assuming they are daisy chained? What if I did the following: Switch A monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 Put all of the ports on vlan 10 because I made an rspan vlan 10 On switch B monitor the ports I need will say 1-10 monitor session 1 source interface fast0/1 - 10 monitor session 1 destination remote vlan 10 as a prerequisite I would have created vlan 10 as a rspan vlan on switch B. Switch A Monitor session 1 destination remote vlan 10 Would this work? By the way I am working with cisco catalyst 3560 switches.

• Port(s) not forwarding?

  - by user11189

  I have cable internet service through Charter Communications and feed two desktop computers through a Linksys RP614v3 router. One system is my wife's running WinXP Home Edition and the other is mine, running Vista Home Premium (sp1). I have port forwarding configured in the Linksys so I can access the Vista system remotely using TightVNC. Initially, it worked great and I was able to remotely tend email and access local files while out of town for work. Lately, the cable internet service appears to flicker intermittently and upon return, my Mailwasher program loses ability to access the net and I've been unable to make the remote connection. When I reset the port forwarded for email in the router control panel, Mailwasher functionality returns but as I'm home when that happens, I have no easy way to check remote access until the next time I'm on the road or at work. I'm at my wit's end -- the TightVNC client accesses fine from my wife's system from behind the modem/router setup but I don't know how to maintain whatever gets reset when I fiddle with the control panel and the need to do so at all is new. I accessed it fine for a week off and on while out of town a month ago and now I can't leave home and access it from work an hour later.

• SSH from ubuntu server to Windows 2008 repeatedly asks for password

  - by jrizos

  I am trying to setup GIT using SSH mode. The central GIT repository is on a NAS device running Windows 2008 server and the user GIT repository is on ubuntu 12.04. When I try to SSH to the windows machine however I am not able to successfully get in. SSH keays are not setup but I think the problem is even before that since I cant get in just by providing the correct password. The output from the SSH command is below.
