• Virtualizing Firewalls/UTM

  - by TheD

  So Sophos UTM (Astaro Gateway UTM) can be virtualized in Hyper-V, VMWare, vSphere etc. Now I'm new to virtualization, so am wondering how the networking would be configured in this situation. Imagine the following (a very simple setup). A Zyxel router acting as the default gateway, standard ADSL line. This is connected directly via Ethernet to my VHost, Hyper-V in my case. Now I assume I need two virtual network adapters, one which is the "External" interface to the firewall, and the other being the "Internal" interface. But where does my switch go, since I have 5 machines (or X number of machines). Where is the switch connected, to the internal interface on the VHost? What default gateway do my clients use etc? How would the routing work if these two interfaces weren't bridged since they are virtual networks anyway. I'm a little confused! Any advice is much appreciated! Cheers

• How can browsers in VMs resolve hostnames of websites on parent PC?

  - by elliot100

  I have a number of local websites in development on my Windows PC, set up as virtual hosts within Apache, with hostnames (along the lines of dev.example.com) resolved via the hosts file, so I can test them out them with various browsers. I now want to extend browser testing to running browsers in various OSs in virtual machines, and want to be able to resolve dev.example.com from the VMs. Currently these are a mix of VMWare Server and VirtualPC. I know I can edit the hosts file on any Windows VMs, but this is a bit fiddly and I'd like a solution which is independent of the individual VMs. I think what I need is a nameserver, but what's the simplest way of going about this? I'd like everything to be self-contained on the one machine. I think I can cover firewall and Apache permissioning issues.

• how to debug mysql has gone?

  - by fefe

  I have a virtual machine(Ubuntu 12.04, MySQL 5.5) running under VMware and is dedicated to host a mysql server. I connect to this server on internal IP. I'm trying to find out why I get mysql server has gone error. One my windows machines apache it stops because of this issue. I have been trying to fine tune my mysql my.cnf with the following parameters but did not bring the desired result. # Instead of skip-networking the default is now to listen only on # localhost which is more compatible and is not less secure. bind-address = 0.0.0.0 # # * Fine Tuning # wait_timeout = 180 key_buffer = 384M max_allowed_packet = 64M thread_stack = 192K thread_cache_size = 8 # This replaces the startup script and checks MyISAM tables if needed # the first time they are touched myisam-recover = BACKUP max_connections = 500 table_cache = 64 #thread_concurrency = 10 # # * Query Cache Configuration # query_cache_limit = 1M query_cache_size = 32M how to debug this issue what is missing from configuration to avoid this error?

• Kill xserver from command line (init 3/5 does not work)

  - by Richard Martinez

  I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

• PDAnet on Android IP on PC is not public IP. Where does the NAT take place, PDAnet or Verizon?

  - by lcbrevard

  When using PDAnet on a PC (Win7 ultimate) to USB tether a Motorola Droid on Verizon 3G the IP address of the PC appears to be public - 64.245.171.115 (64-245-171-115.pools.spcsdns.net) - but connections show as coming from another public IP - 97.14.69.212 (212-sub-97.14.69.myvzw.com). Someone is performing Network Address Translation - either PDAnet or within the Verizon 3G network. Can someone tell me who is doing the NAT? Is it PDAnet or is it at Verizon? Is there any possibility of setting up port forwarding, such that connections to the public IP 97.14.69.212 (212-sub-97.14.69.myvzw.com) are forward to the PC? We are testing a network protocol that requires either a true public IP or forwarding a range of ports from the public Internet to the system on which the software runs (actually Linux hosted by VMware Player or Workstation on a PC running Windows).

• PHP 5 will not work in Centos 6 for me

  - by LaserBeak

  Just created a new install of Centos 6.0 64-bit on a virtual machine and running on Vmware workstation 8, windows host. yum install php service httpd restart And when trying to run a html file from the var\www\html dir which just has <?php phpinfo(); ?> in it or pointing browser to localhost. Nothing comes up. Also opened up httpd.conf and added: AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps Tried reinstalling, installing php-common, then php etc. to no avail. Otherwise going for the typical LAMP. installed: php.x86_64 5.3.2-6.el6_0.1 @updates php-cli.x86_64 5.3.2-6.el6_0.1 @updates php-common.x86_64 5.3.2-6.el6_0.1 @updates Yet to update to Centos 6.1 PHP5 is probably comes installed by default with Centos and I maybe stuffed it up by running yum install php?

• X58 RAID 10 - Am I forced to use Sata2?

  - by Avi

  I'm building a new dev computer. It will be running a few VMWare Worksation virtual machines. I was advised on Serverfault to use Raid10 for performance. Raid 10 uses 4 disks. I contacted my supplier who suggested a gigabyte X58A motherboard and 4 Western Digital Caviar black 6Gb/s disks. I have checked the spec for the X58A board, however, and it says: SATA 3Gb/s: RAID 0, RAID 1, RAID 5, and RAID 10 SATA 6Gb/s: RAID 0, and RAID 1. I'm losing half the bandwidth because I'm forced to use SATA2! What should I do?

• OpenVZ kernel panic

  - by GtoXic

  I recently installed OpenVZ on my VMWare box (To do some testing) and I get the following: https://www.dropbox.com/s/p38btkv5j84bvsh/Capture.JPG the GRUB config is as follows: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.

• Cannot add Windows 7 client to SBS 2008

  - by Sandokan

  I have just installed SBS 2008 R2 Standard on VMware Workstation 9 along with Windows 7 Pro N. Both are activated and running fine. I have followed the steps to configure SBS 2008 and am now at the point where I'm to add a computer to the domain. Here is where the problem begins. I have gone through the steps of using the webinterface. On the client I downloaded Launcher.exe. I then run it and get the error "Check computer requirements - Failed" (translated from swedish): "This computer doesn't reach the requirements for connecting to the network." "The computer doesn't reach the maximum requirements for the operating system with regards to connect to the network" The provided link for More information only leads to a general supportpage and doesn't handle this specific error. I have also checked the time settings and they are correct. Any clue as to what this problem could be?

• Proper way to partition filesystem with Xen

  - by luckytaxi

  I'm coming from a vmware environment, wanting to play with Xen. I have a server with 2 x 500G SATA drives (no hardware RAID available, have to use software-based RAID1). My partitions are all RAID1 except for swap. I left a little over 400G for my VMs and I would like to use LVM for the disk images. For domU's swap, should I allocate that from the 400G or should that be coming from dom0's partition? I asked because I've seen numerous config options that shows either or.

• Why does OVFTool hang randomly?

  - by Billy ONeal

  Hello everyone :) Some great helpers here have shown me the VMWare OVF tool for template deployment. My problem is that the tool itself stops at the "Disk Transfer Completed" step half the time I use it. This seems to be random, and when it happens I have to terminate OVFTool and start the transfer over again. The second attempt usually succeeds. Is there something I have broken on the server that might affect this? I'm using the free edition of ESXi 4.0. Billy3

• Storage replication/mirror over WAN

  - by galitz

  Hello, We are looking at storage replication between two data centers (600km apart) to support an active-passive cluster design for disaster recovery. The OS layer will be mostly Windows Server 2003/2008 with some OpenSuSE Linux used for performance monitoring on VMWare or possibly XenServer. The primary application service to replicate is Nvision. Datacenter 1 will have two storage systems for local active-passive or perhaps active-active replication with Datacenter 2 used as a last resport disaster recovery site. We have a handle on most aspects, but I am looking for specific recommendations on storage platforms that can handle remote replication cleanly. Thanks.

• Does Apache 2.2 (windows) have any default bandwidth limit?

  - by igino manfre'

  I'm running Apache on a server in cloud (Windows server 2008 R2 on VMware, 1 Gbps of BW, http://95.110.164.61 ). I'm streaming many live DVB MPEG Transport Stream, precompressed in loop, (not flash) generated by VLC on port 640xx and then reverse proxied by Apache on port 80. The server's firewall is open for VLC and Apache on all ports. Above 1.5 Mbps the reproduction is affected by continous stop & go. Please note that if you request a stream generated by VLC directly at http://95.110.164.61:64087/mpg2_6.4 you see a correct stream, while if you request http://95.110.164.61/mpg2_6.4 you do not. I know that Flash streaming Server uses Apache to stream on port 80 (and it works). I'm not an expert with Apache, can anyone tell me if any "special" module is required to increase the bandwidth?

• Create a web interface that starts VM's on the server side

  - by xdragonforce

  I am creating a service called TorCompute which allows for creating virtual Tor Hidden Service servers on my infrastructure (I say infrastructure, by that I mean just the 3x 32GB RAM machines waiting to be purchased). What I would like to be able to do is for users to log on, access the web interface and spin up a VM with a variable about of RAM/Disk Space. I've written the PHP for logging in and have a nice web interface, just I need the code to actually create them! How would I go about doing this? Thanks, Stewart EDIT: I will run them with VMWare Server, with vmrun

• Using Hamachi VPN to connect to Linux VM at home

  - by Cameron Verotti

  I have a CentOS 5.10 Linux box at home running on VMWare, with Windows 2008 as the host. I have set up a Hamachi VPN so that I can connect to the Host server from work, I attempted to add a second VNIC to the VM and bridged it to the hamachi Network Interface. I spun up the VM and checked eth1 with ifconfig and its throwing me a ipv6 address not a ipv4. I want to hook this VM up so that I can run a ssh command from work to the VM. MY network at home is all on Local 198.168.. hence the need to make a VPN network like Hamachi. I cannot seem to find anything that tells me or helps me with tunneling my Linux VM via Hamachi. Any help would be fantastic!

• Maintaining a set of (virtual) windows XP machines

  - by Frank Meulenaar

  I have a small set (currently 3, going to 6, not going to be more than 10) of (virtual, vmware workstation) windows XP machine's. They are similar but not exactly the same. I'm currently rolling out windows updates etc by hand: start machine 1, update, close, etc; I'd like to review the updates first before the clients can install them. Incidentally there are also other updates to be performed: changes some files on all machines, install new Java versions, etc. What's a good way of doing this automatic? I tried to search for this but things like Active Directory seem overkill to me.

• Does Citrix XenServer have storage Migration

  - by Entity_Razer

  I'm trying to find out. I can't seem to find a defenitive yes / no answers so I thought I'd ask the ServerFault community this simple question: Does XenServer (in any version) support Storage migration such as VMWare's Storage VMotion capability, or Hyper-V's storage migration ? I'm trying to do a comparative study of all platforms but I can't find a website (preff. Citrix supported or any other "legit" source) where it say's a defenitive yes or no. Anyone able to answer this one for me ? Cheers !

• Mac OS X Lion (10.7.3) Virtual Machine?

  - by Ben Hooper

  I have been looking into this for a while and have attempted quite a few "solutions" (hackintosh boot images, universal unlockers, etc) before I gave in and asked for help. I know this is extremely difficult to accomplish, especially with an AMD CPU, but it has been done and it can't hurt to ask. Question Does anyone know of any way to actually get Mac OS X Lion (10.7.3) to boot in VMware Workstation 8.0.2? I know that Mac OS X is heavily dependant on hardware configuration, so I will post my PC's hardware below, if it helps. As far as I know it's only reliant on the CPU, but I will post it all just in case. PC Hardware Motherboard: ASUS M4A77T CPU: AMD Phenom II x4 955 Black Edition Graphics Card: Palit Sonic Platinum nVIDIA Geforce GTX 460 Memory: G-Skill [RipjawsX F3-12800CL9D-8GBXL] 8GB PSU: Arctic Power 700(W) Hard Drive: SAMSUNG HD204UI 2TB Thanks in advance. :)

• Nagios dropping ICMP packets

  - by Ankh2054

  I am running a Nagios server on vmware 4.0 and every now and again during the day it alerts that some of servers cannot be reached via ICMP, clearly staging that a certain percentage of packets send are lost. This does not happen to all servers. I know the servers are actually up, because I have done a parallel test from another windows box, just using simple ping and no packets were lost. I also now from the way we monitor out switch that no packets were lost on those particular ports. Could anyone suggest a way to troubelshoot this further ? AT present this points to the nagios server itself loosing packets. thanks

• Windows 7 + NVidia == 640x480 on external projectors

  - by ben2004uk

  Hello, I'm having a major problem and I really need your help! I have a MacBook Air which has the NVidia 9400M. The problem is, when I connect it to an external projector Windows 7 (and Vista) only allow me to connect at 640x480. I need it to use the laptop to present at conferences, as such I need it to work on a number of different projectors - at the moment I need to use OSX and VMWare but it's painfully slow and really doesn't work. At the moment, I'm considering buying a new laptop :( Is there any way to override the screen resolutions provided? I've saw some information around EDID? Thanks Ben

  I can't access any share from my operating system, including \\localhost and \\127.0.0.1. I have Windows 7. NetBIOS over IP is enabled, other computers in the network can access my shares and other computer's shares, but my operating system cannot access any share. I have installed Windows XP within VMware, and the virtual windows xp can access all shares including the host shares. I can communicate in other ways like TCP, HTTP and gaming, but not access shares. How to solve this problem?

• How do I remove Windows Update uninstall files on Windows Server 2008?

  - by Robert Koritnik

  I'm running Windows Server 2008 Standard running in VMware. It has 2 disks: system disk: 16 GB data disk: 500 MB I installed Visual Studio 2008 SP1 + MSDN and some small tools and libraries that don't take much space. Over time the system disk's free space has been going down (I suspect because of regular system updates - NetFx (.NET), service packs, and regular updates). Questions 1 How do you remove Windows Update uninstall files from Windows Server 2008? Question 2 I also found lots of files in C:/Windows/Installer folder. Is it possible to determine which .msp file goes with which patch? I would like to delete some of them, because they do take a lot of space.

• Managing MS Exchange server-side email rules on Mac OS X?

  - by Doug Harris

  Has anybody found an easy way to manage server-side rules from Mac OS X? Here's a brief list of what I know doesn't work: Entourage 2008 - it supports client rules, but not server rules. No good, there are certain actions that should happen before I open my laptop or check my email on my iPhone. Apple Mail - same as Entourage, but at least I don't get as frustrated since, unlike Entourage, this isn't a Microsoft product. Web mail (aka Outlook Web Access) - perhaps you can manage rule in the fancy version which Exchange serves to IE, but not with the browsers available on a Mac. I manage this now by launching a VMWare virtual machine running Windows XP and Outlook. I don't count that as an easy way. Update, post release of Office 2011 Does MS Outlook 2011 have the ability to manage server-side rules? Update, post installation of Office 2011 No. Outlook 2011 doesn't have this ability. I've already removed my account from Outlook and switched back to Apple Mail and iCal

• How can I access a Web server in a VM from an iPad?

  - by Nick Haslam

  I have a virtual machine (running Windows Server 2012, if it's relevant), on VMware Workstation. It is running an Apache Tomcat web server, and I'm wanting to access that webserver from an iPad. Is this feasible, or even possible ? I have tried running Connectify Hotspot on the host machine, but that only gets me as far as being able to access a webpage on the host machine. It doesn't look to pass the connection through to the VM as they are on different subnets. Any thoughts are gratefully received.

• VPN server on Windows Server 2008 for a small office

  - by cmbrnt

  I'm going to refurbish the IT-infrastructure for a small organization with one single office, and I'm not sure what VPN server to use. In your opinion, would the built-in Windows Server 2008 VPN server suffice or are there any specific problems with it as opposed to, for example, OpenVPN? I'd rather run a Windows native VPN server, but if there are few (preferably free) good alternatives, I could install VMware ESXi and virtualize both Windows and an OpenVPN-server. By the way, because of a low budget this office runs a solution with only one physical server. Any advice would be great to help me grasp this field of which I'm quite a novice. Thank you!
