  • Virtual Hard Drive not booting - VMWare

    - by Chloraphil
    I have a .vmdk (VMWare hard disk) file that I cannot use as the lone disk in a new virtual machine. If I attach it to an existing virtual machine then it works fine. It has Windows Server 2003 on it. When I attempt to boot the new VM it attempts a network boot. EDIT: VMWare Workstation 6.5 I could not find a PXE option in the settings, and I did look in the VM config file for "PXE" but did not find one.

  • How to boot more than 1 linux distro along with windows?

    - by BD at Rivenhill
    I have a machine that currently has Windows Vista living peacefully with Ubuntu 10.04 but I would like to test out another distro outside of a virtual machine without destroying my current Ubuntu or Windows installs. Is this possible? If so, any recommendations on how to arrange the partitions? I was thinking of moving user home areas to a separate partition and having 1 partition for all Ubuntu files and 1 for all files associated with the other distro.

  • How to associate localhost in Snow Leopard to a specific ip ?

    - by Patrick
    I've disabled the web server on Snow Leopard, and I'm using an emulated Ubuntu with Lighttpd web server. In order to access to the web pages I need to specify the ip of the emulated machine. However I now need to associated such ip with "localhost" in Leopard environment. When I type localhost in Leopard I actually want to visit the localhost on the Ubuntu machine. Do I need apache on leopard to make the forward or can I change network settings in Leopard or what ? thanks

  • Configuration to point an X tty to a separate system?

    - by buu700
    Specifically, I have an Ubuntu 10.04 system with a headless Ubuntu 12.04 virtual machine, and I'm looking for a way to have it set up so pressing ctrl+alt+F8 will take me into another X client which is connected to an X server on the vm (with gdm appropriately displayed at startup, etc.). As in, my startup script should spin up the headless machine and then immediately perform a "startx" pointed at the vm.

  • Is this iptables NAT exploitable from the external side?

    - by Karma Fusebox
    Could you please have a short look on this simple iptables/NAT-Setup, I believe it has a fairly serious security issue (due to being too simple). On this network there is one internet-connected machine (running Debian Squeeze/2.6.32-5 with iptables 1.4.8) acting as NAT/Gateway for the handful of clients in 192.168/24. The machine has two NICs: eth0: internet-faced eth1: LAN-faced, 192.168.0.1, the default GW for 192.168/24 Routing table is two-NICs-default without manual changes: Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 (externalNet) 0.0.0.0 255.255.252.0 U 0 0 0 eth0 0.0.0.0 (externalGW) 0.0.0.0 UG 0 0 0 eth0 The NAT is then enabled only and merely by these actions, there are no more iptables rules: echo 1 > /proc/sys/net/ipv4/ip_forward /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # (all iptables policies are ACCEPT) This does the job, but I miss several things here which I believe could be a security issue: there is no restriction about allowed source interfaces or source networks at all there is no firewalling part such as: (set policies to DROP) /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT And thus, the questions of my sleepless nights are: Is this NAT-service available to anyone in the world who sets this machine as his default gateway? I'd say yes it is, because there is nothing indicating that an incoming external connection (via eth0) should be handled any different than an incoming internal connection (via eth1) as long as the output-interface is eth0 - and routing-wise that holds true for both external und internal clients that want to access the internet. So if I am right, anyone could use this machine as open proxy by having his packets NATted here. So please tell me if that's right or why it is not. As a "hotfix" I have added a "-s 192.168.0.0/24" option to the NAT-starting command. I would like to know if not using this option was indeed a security issue or just irrelevant thanks to some mechanism I am not aware of. As the policies are all ACCEPT, there is currently no restriction on forwarding eth1 to eth0 (internal to external). But what are the effective implications of currently NOT having the restriction that only RELATED and ESTABLISHED states are forwarded from eth0 to eth1 (external to internal)? In other words, should I rather change the policies to DROP and apply the two "firewalling" rules I mentioned above or is the lack of them not affecting security? Thanks for clarification!

  • Windows Server not installing audio drivers properly

    - by Adrian
    I am trying to install a dummy sound card on a Windows Server machine (in Amazon EC2 cloud) in order for one of my application to work. I'm trying to accomplish that with Virtual Audio Cable and REAUDIO3. Both tools managed to install a new device on my Windows XP machine, but on Windows Server, no new devices appear. Windows Audio and Plug and Play services are Started and Automatic. ANY ideas are greatly appreciated.

  • Available shells in plesk

    - by jr0d
    Does anyone know where plesk pulls its list of available shells under the domain setup page? I am on a box which is missing /bin/bash (chroot), though the majority of the system users on the machine have the shell: /usr/local/psa/bin/chrootsh On a redhat/centos machine, chrootsh is provided by the base psa package. I have also checked that chrootsh is specified in /etc/shells. I have poked around the psa database, but have not been able to ascertain where the drop down box is populated from.

  • Cross-reference of computers having virtualization technology [closed]

    - by msorens
    When considering obtaining a new computer one of my prerequisites is the ability to load Windows 8 in a virtual machine (using VirtualBox). A prerequisite for that is that the host computer have virtualization technology. I located an Intel cross reference of chips having virtualization technology but I am trying to find a "higher level" cross reference between computer models and virtualization technology availability, skipping the extra step of having to first look up what CPU chip is in a machine, then cross-referencing that on Intel's list.

  • How can I direct rsync output / log to the remote server?

    - by Guest
    I am able to output rsync logs on the client machine using --log-file=FILE but I want the output to be sent to the server instead. The client is a W7 machine (cygwin) and the server a Linux NAS. This is the command I use which successfully logs the file on the client. I'm looking to have the file sent to the server instead: rsync -PavOs --delete --log-file=/somepath/rsynclog.txt -e "ssh -i /somepath/keyfile -p 1000" "/somepath/User/" [email protected]:/somepath/User/ Thanks

  • Moving a Domain Controller VM from one server to another

    - by Mike
    I have a Hyper-V Virtual Machine that is a Domain Controller, specifically it is our main DC and holds all 5 FSMO roles. If I wanted to move this Virtual Machine to another VM Server than the one it is on currently, is it as simple as taking the .VHD, moving it to another server, and creating a VM in Hyper-V on the new server for it? Or are there other things to consider that could get screwed up from doing this? Thanks

  • monitoring service to detect when email is not received

    - by DGM
    I would like to monitor an email server - not whether the port is open and receiving, but rather that a "canary" message sent every so often actually arrives somewhere else. I have had a problem with a server getting firewalled off and no one noticing that cron jobs are not coming from the machine for a few weeks. Of course, the machine itself cannot send out a notification if it is having problems, so this requires an outside service. Any ideas?

Is there any default firewall settings that I have to change?

  • For how long should I expect my hardware to work?

    - by Makach
    I got this old box with windows xp home. It works perfectly, except the occasional blue-screen when shutting down the machine. How long should I expect this, or any, machine to work, when will the hardware start failing and should I worry about silly things like upgrading the os? What is the TTL on HW you purchase today?

  • Remote Server: Please wait for the System Event Notification Service

    - by Jeff Handley
    I was rebooting a remote server (Windows Server 2008 R2 Standard) over remote desktop and the session now shows the blue screen during the shutdown sequence, and the message "Please wait for the System Event Notification Service..." It seems that everything is still running on the server (for instance, http://jeffhandley.com is still responding), but I need to get the machine to finish the reboot sequence. How can I force the machine past this point? It's been stuck there for about 30 minutes.

  • Outlook 2007 + Windows 7 + Exchange Server = slow sync

    - by wacky_doug
    I just upgraded a Vista machine to Windows 7. The machine is running Outlook 2007 SP2 with the KB970944 performance hot fix. Now, syncing to the Exchange server can take 20 minutes, whereas it was very fast before the Windows 7 upgrade. I believe we're running Exchange 2003, but I'm not 100% sure. Anyone else seeing this? Any fixes yet?
