• Virtual Machine Network Services causes networking problems in Vista Enterprise 64 bit install

  - by Bill

  I have a Quad-core/8GB Vista Enterprise 64-bit (SP2) installation on which I installed Virtual PC 2007. I have a problem that is opposite of all that I found searching around the Internet--everybody has problems making network connections from their guest VM. When Virtual Machine Network Services is enabled in the protocol stack for my network card across a reboot, it causes access problems to the network. The amount of time to login in using a domain credentialed account is upwards of 3 minutes, then after reaching the desktop the network and sharing center shows that my connection to the domain is unauthenticated. Disabling and re-enabling the Virtual Machine Network Services (uncheck in network properties/apply/recheck/apply) fixes the problem. And as long as I have the VMNS disabled when I shutdown the restart runs smoothly. I just have to remember to enable after login and disable before shutdown. I have un-installed and re-installed Virtual PC 2007 multiple times with restarts between. The install consists of the SP1 + a KB patch for guest resolution fix. Any help would be greatly appreciated. Some additional information... At one point during my hairpulling and teethgnashing with this, I tried to ping my primary DC and observed some weird responses: (Our DC is 10.10.10.25, my dynamic IP was 10.10.10.203) Reply from 10.10.10.203, Destination host unreachable. Request timed out. Reply from 10.10.10.25: ... This is not consistently repeatable, but thought it might strike a chord with someone.

• XenServer VMs can't reach network

  - by toto

  I'm currently trying to setup a small cloud architecture , I'm using in the installation CloudStack 2.2.14 which need two node : a management server (as node1) to provision the cloud and a hyperviser XenServer 5.6 SP2 to host the VMs (as node2). I succeded to create both node1 and node2 into an ESXi 5 VMWare as VMs. So The ESXi 5 is hosting two VMs node1 + node2 , and node2 which is the XenServer will host also VMs (such as ubuntu or Centos). Both node1 and node2 can ping each other and can get the internet connection from Esxi5 ,but My problem is : that VMs into the node2(XenServer) can't reach the network (can't ping node1 or Esxi or get an internet connection but they can ping VMs IN the node2(XenServer). So I tried to: 1-Setup a DHCP server as node3 in ESXi5 and connect node2(Xenserver) to him , but always the VMs into to node2 can't reach the outer network. 2-Setup a DCHP server into node2 , but always the same problem. So , 1-is there any other configuration i'm missing in node2 (considering that I'm sure about DNS , GW , NETMASK configuration)?. 2-Is it the problem because i'm Creating VMs into node2(XenSever) which is a VM into ESXi 5 ?

• How do I log back into a Windows Server 2003 guest OS after Hyper-V integration services installs and breaks my domain logins?

  - by Warren P

  After installing Hyper-V integration services, I appear to have a problem with logging in to my Windows Server 2003 virtual machine. Incorrect passwords and logins give the usual error message, but a correct login/password gives me this message: Windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not found. Please try again later. If this message continues to appear, contact your system administrator for assistance. Nothing pleases me more than Microsoft telling me (the ersatz system administrator) to contact my system administrator for help, when I suspect that I'm hooped. The virtual machine has a valid network connection, and has decided to invalidate all my previous logins on this account, so I can't log in and remotely fix anything, and I can't remotely connect to it from outside either. This appears to be a catch 22. Unfortunately I don't know any non-domain local logins for this virtual machine, so I suspect I am basically hooped, or that I need ophcrack. is there any alternative to ophcrack? Second and related question; I used Disk2VHD to do the conversion, and I could log in fine several times, until after the Hyper-V integration services were installed, then suddenly this happens and I can't log in now - was there something I did wrong? I can't get networking working inside the VM BEFORE I install integration services, and at the very moment that integration services is being installed, I'm getting locked out like this. I probably should always know the local login of any machine I'm upgrading so I don't get stuck like this in the future.... great. Now I am reminded again of this.

• One server with multiple desktops "heads" with VNC

  - by Alexis K

  I am managing a system of kiosks. Each kiosk currently is running a web browser with the application for the kiosk running in the browser. Each kiosk needs to be able to display separate content. At times, the application running in the web browser freezes. Thus, I have to go out to the site to refresh the page. I want to see if there is a way to have one central server that has multiple browser heads. Then each kiosk would run a program like VNC to display one of the heads. This way when the program freezes, I just have to login to the central server and refresh the page. Getting VNC or another remote desktop software installed on the clients is no problem. What I am looking for is a way to have VNC remote into a specific head of a head of a web browser. Does such a thing exist? Or do I have to run a VM for each kiosk to remote into? Any advice, pointers, or solutions would be helpful.

• Defragging Host OS of VMWare

  - by JackLocke

  Hi All, I want to ask something that has been puzzling me from last few days. I will try to explain my problem as clear as I can ... I have VMWare Workstation installed in my machine. And I use one separate 100Gb drive which stores all of my virtual machines, nothing else. Now, last week I was playing with a De-fragmentation tool called "Smart Defrag" which showed me in its analysis report that my drive where I am currently storing all of my Virtual Machines has more than 80% of fragmentation !!! Now my question is ... What will be the effect on my Guest / VM machine performance if I defrag my Host machine ... I mean this Host machine is essentially storing those virtual machines, but still dont have any direct access to what ever is stored in those machines ... so defraging the host should not cause any problem. But before proceeding, I want to hear from other people who may have met same problem. I will really appreciate any help ... BTW, I am using Windows 7 as Host and the guest machines I am using are Windows 2008 & 2003 & Ubuntu 10.04 THanks, Jack

• Safely remove external USB drive fails due to $extend

  - by moontear

  When connecting an external USB 3.0 hard drive to my USB 3.0 ports I can never safely remove it. Somehow windows always keeps the journal files open: "Always" as in this time I only connected the drive, copied a 10GB VM and wanted to disconnect it afterwards (like 15 minutes after copying, so all copying was done). As you can see there is no other program keeping a handle on the disk besides System. I tried restarting explorer.exe as well as RemoveDrive.exe from Uwe Sieber. No luck, the locks on the hard drive always remain. My only solution is just unplugging it (whereas I'm afraid of damaging the data?) or restarting the computer (always helps, doesn't it?). Might it have something to do with me only having a SSD hard drive and the external disk is a regular drive? Might it have something to do with the USB 3.0 drivers (NEC Electronics USB Hub)? I never have this problem when using the regular USB 2.0 ports. Any ideas on how to properly unmount the disk?

• Can't Install Win2k8 On KVM - Classic 0x80070013 error

  - by javano

  I am trying to install Win2k8 Std as a KVM guest on Debian Squeeze. As you can see from these screen shots; No drives are detected (I have blanked out a 20GB image for testing) - screenshot1 I am using this driver CD: - screenshot2 I have signed the Win7 driver (I assume this was the most appropriate one?) - screenshot3 I can now see an unpartitioned drive - screenshot4 But I can't create a new partition on here, getting the error code 0x80070013 - screenshot5 I have had this error code before but only on a physical server. If I remember correctly it was complaining because the disks were partitioned as GPT (because it was a server that was being re-purposed) so repartitioning with an MS-DOS table fixed that. This is a blank disk image though. What is wrong here, and how can I correct this? Thank you. UPDATE I have booted the VM with a Gparted-Live disk and formatted this volume with an MS-DOS partitioning scheme, and a single 20GB NTFS file system. Now when I boot the Win2k8 CD, load my drivers, I get a different error. As you can see at the bottom of screenshot6 "Windows cannot be installed on this hard drive space. Windows must be installed to a partition formatted as NTFS". Clicking format produces the error (0x80004005) on the screen, so I think this is still a driver issue because Windows can see the drive but not interact with it properly. Is that insane thinking?

• How do I enable additional debugging output from Ansible and Vagrant?

  - by Brian Lyttle

  I'm investigating Ansible for server and application provisioning. My application is currently provisioned with shell scripts in Vagrant. Rather than rewrite my scripts I've taken a sample and attempted to deploy it. It appears to deploy fine, but I've seeing a failure message after what looks like a series of successful steps: » vagrant provision ~/vm/blvagrant 1 ? [default] Running provisioner: ansible...

• Should I keep my ex-employer's data?

  - by Jurily

  Following my brief reign as System Monkey, I am now faced with a dilemma: I did successfully create a backup and a test VM, both on my laptop, as no computer at work had enough free disk space. I didn't delete the backup yet, as it's still the only one of its kind in the company's history. The original is running on a hard drive in continuous use since 2006. There is now only one person left at the company, who knows what a backup is, and they're unlikely to hire someone else, for reasons very closely related to my departure. Last time I tried to talk to them about the importance of backups, they thought I was threatening them. Should I keep it? Pros: I get to save people from their own stupidity (the unofficial sysadmin motto, as far as I know) I get to say "I told you so" when they come begging for help, and feel good about it I get to say nice things about myself on my next job interview Nice clean conscience Bonus rep with the appropriate deities Cons: Legal problems: even if I do help them out with it, they might just sue me for keeping it anyway, although given the circumstances I think I have a good case Legal problems: given the nature of the job and their security, if something leaks, I'm a likely target for retaliation Legal problems: whatever else I didn't think about I need more space for porn. Legal problems. What would you do?

• linux "date -s" command not working to change date on a server

• Windows 8 x64 with VMWare Workstation or inside ESXi

  - by Dommer

  I need to run several virtual machines on a core i7-920 box with 12GB or RAM and a 256GB SSD to host the VMs. It also has a Highpoint RocketRaid 2720SGL RAID controller with a 12TB RAID 5 array. I want one of my VMs to run Windows 8 x64, to have access to the RAID array as a native disk (not as networked drives and it needs to run at full speed) and to be able to send files quickly across the network. Initially I thought I'd try to do this using ESXi 5, but I have been unable to find any working RAID drivers for the RR2720SGL and it is not on the HCL for ESXi 5. In light of this, I have installed Windows 8 x64 on the hardware and am thinking of installing VMWare Workstation and running my VMs inside there. I guess my questions are these: How does VMWare Workstation 9 perform compared to ESXi 5? In the real world I mean? Presumably installing Win 8 as the host OS will give me way better performance for that Win 8 machine than Win 8 running under ESXi? I should stick with Windows 8 x64 as the host OS, right? If I install a domain controller VM inside my Win 8 box and join the Win 8 machine to that domain, am I insane (I would guess the Win 8 machine wouldn't see the domain controller until it finished starting everything up, but I don't think that matters)?! is it feasible to give metrics like this and if so, what is the likely value of x? 25%? 50%? 75%? Win 8 under ESXi runs x% as fast as Win 8 installed bare metal.

• Instructions to setup primary and only domain controller

  - by Robert Koritnik

  Where could I get best step by step instructions (with some simple explanations) how to setup domain controller on Windows Server 2008 R2 Server Core? I don't know what do I need? Do I need DNS as well and AD and so on and so forth. I don't know enough about these things, but I need to set them up to prepare development environment. I would also like to know how to configure firewall on DC machine, to make it visible on other machines because I've setup DC somehow but I can't connect to it... This is my HW config: Linksys internet router with DHCP my dev machine is Windows 7 my DC machine is a VM in my dev machine my dev machine has a hw network adapter to linksys and a virtual network adapter to DC DC machine has two network adapters: one to linksys (to be internet connected so it can be updated etc.) and one to host (my dev Win7 machine) Edit My development machine should access domain controller and logon using domain credentials. Development machine would access internet directly via Linksys router. My domain controller machine would only serve authentication (and if I'm able to configure it right) should also have Active Directory Federation Services in a workable condition. I hope this is a bit more clear now. At least a small bit.

• Problem with Strange VMWare behaviour when shutting down guest.

  - by adza77

  Hi, I've been having a problem for a while now with VMWare Workstaion. (Originally with 6.5, but now with 7.0 and 7.0.1 too). The problem occurs when I choose to shut down a guest. VMWare itself seems to hang. If I choose to shut down a guest that's opened full screen, and during the process I minimise the screen to work on other applications in the host, often (not all the time) when I return to the guest I have a 'greyed out' screen and the system becomes unresponsive. The host O/S still seems to be working, but I am unable to switch to other applications. (I can bring up the taskbar on the host and 'see' other applications and even switch to them, but VMWare still stays 'on top' being unresponsive). I can not terminate VMWare even when windows says that the application has become unresponsive and gives me the option to terminate. VMWare stays on top, and I'm forced to either shutdown, or log off and log back on in order to regain control of my computer. This happens with both Windows 7 and Windows Vista guest operating systems (32 bit), and I have had it happen on multiple host machines, and multiple guest machines too. Current Host: Windows 7 64 bit, 8GB Ram, 500GB HDD, i7 Processor. I have been searching for more than 6 months for a solution but have found none, so finally decided to post here. Does anyone know what might be causing the problem (+or even how to minimize the VM so I can at least access any other applications and save work before forcing a logoff / reboot+) would be extrememly handly. If I know the correct keystrokes to save and close in an application on the host I can do this by task-switching to the desired app to save and close successfully, but I can't see what I'm doing because VMWare Workstation is still on-top 'greyed' out. Cheers Adam.

• RTNETLINK answers: File exists... maybe because assigned a new mac adress

  - by steven

  I got a "RTNETLINK answers: File exists Failed to bring up eth0:1" on "ifup eth0:1". I suspect it happens because i assigned a new mac adress in my VM's network adapter. Can you tell me how to fix the issue? My configuration looks like this: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.1.80 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.1 # Alias being connected to 192.168.10.x Network auto eth0:1 allow-hotplug eth0:1 iface eth0:1 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 Why do I get "RTNETLINK answer: File exists.." suddenly? I worked with this configuration before without problems. All i did in the past is to renew the adapters mac adress. At the moment I am connected to the 192.168.10.x Network and if I do /etc/init.d/networking stop /etc/init.d/networking start then i got "RTNETLINK [...] falied to bring up eth0:1" but the strage thing is that i am able to connect to 192.168.10.83 via ssh from my host machine. But I cannot reach the internet from the debian client. I hope it is clear what my problem is, now. update if i change my /etc/network/interfaces like this then "ifup eth0" fails, too with the same error! # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 with verbose option enabled i got: Configuring interfache eth0=eth0 (inet) run-parts --verbose /etc/network/if-pre-up.d ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0 RTNETLINK answers: File exists Failed to bring up eth0. same if i type this manually: ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0

• Windows VirtualBox failed to attach USB device to Linux Guest

  - by joltmode

  I have Windows 7 64bit Host system, and I am using VirtualBox 4.1.18 (r78361). I have an Arch Linux Guest OS. I have installed VirtualBox Extension Pack (to enable USB2 support) and added my USB device filter to VM. I have also installed the Guest Additions provided by Arch: virtualbox-archlinux-additions (but I have no idea whether it's actually needed for my environment). I can see my USB device from VirtualBox Devices menu. Whenever I am trying to access it, I end up with: Failed to attach the USB device Kingston DT 100 G2 [0100] to the virtual machine Archlinux. USB device 'Kingston DT 100 G2' with UUID {a836ec33-0f41-4ca7-a31d-09cceaf5d173} is busy with a previous request. Please try again later. Details ? Result Code:    E_INVALIDARG (0x80070057) Component:      HostUSBDevice Interface:      IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a} Callee:         IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} From what I have googled, most guides shows how to solve this the other way around - Linux Host to Windows Guest. How do I resolve this? Update I have tried to Eject (virtually, not physically) the device from my Windows Host system and then try to access the Device from Guest. Same error.

• Why do I need to set up Autologon values in registry twice before it works and can i fix this?

  - by jJack

  Background: As part an automated testing suite I am building, I need to set up Autologon on my virtual machines 'on demand'. By on demand, I mean that I don't want to necessarily pre-configure my VM or any snapshot to have Autologon set up already, for security reasons and also a huge business case. My solution so far: I'm copying a script to the guest machine and then using Sysinternals PsExec to execute it. The script is: reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultUserName /t REG_SZ /d myusername reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultPassword /t REG_SZ /d myfakepassword reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultDomainName /t REG_SZ /d mydomain reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v ForceAutoLogon /t REG_SZ /d 1 reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v AutoAdminLogon /t REG_SZ /d 1 reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoLogonChecked" /f /ve /d 1 Note: I don't believe AutoLogonChecked is required for machines post Windows 2000 but I'm doing it just in case for now. Maybe ForceAutoLogon isn't either, not sure yet. The Problem: I see PsExec executes this properly and all the values are in the registry, however when I restart the machine, the user isn't automatically logged on...When I run this a second time then restart the machine, the user is finally logged on. A diff between the registry states shows that the first time I run this, it is missing both the "1" for AutoAdminLogon, and also the DefaultPassword key. The second time I execute it, these values are correctly intact as I intended. So, what is going on here? Is this expected? This post claims in the end that it really all just works (the problem was that a logoff script was setting off the values). Doesn't seem to work for me however.

• What games work well on MacBook Pro (i7/GeForce GT 330M) within VMWare Fusion?

  - by webworm

  I have a 15" MacBook Pro (2.66 i7 with 8 GB RAM) with the GeForce GT 330M 512 MB graphics card. I use it primarily for development (Mac/Web/Windows) though I would like to play the occasional game with my son who uses a desktop PC system at home. I prefer to use VMWare Fusion for virtualization rather than BootCamp for a number of reasons. Heat/Fan issues with i7 under BootCamp Prefer to retain virtual machine as single file rather than dedicated partition (easier to move a nd backup) I have heard that Windows support of the GeForce GT 330 in BootCamp is not all that good. So that being said I was wondering what sort of games I would be able to play within the Fusion environment running Windows 7. I have 8 GB RAM and usually dedicate 4 GB to the virtual machine. I don't expect to be able to play the latest FPS games such as BattleField: Bad Company 2 or Call of Duty, rather I am looking at games such a Total War II, Civilizations IV, Supreme Commander, and other RTS type games. I should mention the native screen resolution of my MacBook Pro is 1680x1050, which is what I would be most likely running the VM at (fullscreen). Thank you for any advice.

• Missing drive space in Server 2003

  - by Tim Brigham

  I have two drives used for SQL backups which for the last week have been acting strange - the free space indicated by windows is far off from what windirstat, etc indicates. There should only be about 60 GB of drive space used and there is about 160. This would match the utilization if the two last backup files were still residing on disk. SQL server is 2000, OS Server 2003 x64. Running on a VMware 5.0 cluster. OSSEC and McAfee for this system shows clean. My current plan is to temporarily attach one of these drives this drive to another VM for analysis. Is there anything more I should be looking at? There were a lot of pages on the net when I was looking for documentation on this issue but I haven't found this case described. EDIT: Unfortunately even a full reboot did not clear this behavior. I also used process explorer to look for open file handles. No dice.

• MAMP Pro mysqld won't start on os x lion

I can't find where MAMP has set --skip-locking set, my.cnf doesnt have it anywhere. Activity monitor gives me a mysqld process running by me, and everytime i KILL the process both via Activity Monitor and via kill =9 pid it starts right back up.. Sampling the process points back to the MAMP mysqld.. wtf?! About to throw MAMP out the window and boot up a VM of CentOS =)

• Adding subnet to a vsphere with single vcenter and esxi host

  - by Ilya Rakhlin

  Let me start of by saying that I do not specialize in networking, I am in the process of adding additional VMs to a testing environment and wanted some recommendations. In this case I am running a single ESXI 5.1 host and a single Vcenter management server. The problem is, I need another range of IP addresses added to the existing setup; hopefully without reconfiguring everything. Currently the esxi host is configured to IP: 192.168.100.200, gateway: 192.168.100.1 and subnet: 255.255.255.0. All of the VMs are running some version of linux with hard coded IP addresses in that range, and using that subnet. The VMs I am about to deploy I want to be on the 192.168.101.X network. Is it possible to add an additional subnet to this existing system that will also communicate with the current subnet? The esxi host has 6 physical NICs but only one connected as it is only a testing system; not sure if that matters. Are there any other ways to accomplish this hopefully without restarting or at least reconfiguring the IP addresses for each VM? Reason: Due to the configuration of the VMs to run the applications that we need I am using a large amount of the current IPs in the potential range (mostly VIPs). I will be setting up a new version of this “environment” while keeping the old one, thus potentially running out of IP addresses.

• Slow browsing through IE on Windows Server 2012

  - by Volodymyr

  We've run into strange issue on the freshly installed servers. H/W: IBM server X3550 M4 7914; OS: Windows Server 2012 Std. Then we try to browse on the servers thru IE, not all sites are opened or it takes too long time to open the page, i.e. very few of them can be opened. Local FW are disabled. Servers are in a new subnet and traffic is allowed for it. VLAN is configured properly Another Windows Server 2012 host is running OK and Internet access works fine, but it is VM running on Hyper-V 2012. No proxy is used on the network. At the same time, if one tries to establish telnet session to any site on 80/443 ports - it does work. Google works as well. I've tried to configure single Qlogic adapter to check if the issue remains - it does. Teaming is configured with the means of QLogic, not by built-in functionality. IE Enhanced Security is disabled. IE settings were reset, more than once. Why would certain sites work while others not - Idk. I also tried to disable ecncapability and restart server - no luck netsh int tcp set global ecncapability=disabled Any thoughts? UPD1 VMQ is disabled. Servers are not running Hyper-V. UPD2 Servers were rebuilt from scratch, got a mail a few mins ago. Issue still remains. Teaming is now configured with the means of Windows Server 2012.

• Setting Remote Desktop to allows IPv6 connections

  - by Garrett

  Setup: Basically I have 3 machines (2 virtual and 1 physical) that I would like to be able to RDP in to from outside my NAT (a router). The VMs are Windows 7 and Windows XP, both fully patched with Teredo installed and working, both running in VirtualBox (their host also has Teredo working, though I'm not sure if that matters). They both have bridged network adapters with promiscuous mode enabled. The physical machine is Windows 7 fully patched with an HFS server running on it and a dynamic DNS set up for my public IPv4 address and port forwarded. It also has Teredo installed and working. Symptoms: According to http://test-ipv6.com/ all 3 have public IPv6 addresses, and they can all connect to http://ipv6.google.com/. I can ping the XP VM from the host it's running on but I cannot ping it from any other machine. Also, I cannot ping either of the other machines from anywhere. I cannot connect to any of them over RDP from IPv6, however I can connect to all of them through IPv4. Any ideas what is going wrong?

• How can I setup a Proxy I can sniff traffic from using an ESX vswitch in promiscuous mode?

  - by sandroid

  I have a pretty specific requirement, detailed below. Here's what I'm not looking for help for, to keep things tidy and on topic: How to configure a standard proxy Any ESX setup required to facilitate traffic sniffing How to sniff traffic Any changes in design (my scope limits me) I need to setup a test environment for a network-sniffing based HTTP app monitoring tool, and I need to troubleshoot a client issue but he only has a prod network, so making changes to the config on client's system "just to try" is costly. The goal here is to create a similar system in my lab, and hit the client's webapp and redirect my traffic - using a proxy - into the lab environment. The reason I want to use a proxy is so that only this specific traffic is redirected for all to see, and not all my web traffic (like my visits to serverfault :P). Everything will run inside an ESX 4.1 machine. In there, there is a traffic collection vswitch in promiscuous mode that is not on the local network for security reasons. The VM containing our listening agent is connected to this vswitch. On the same ESX host, I will setup a basic linux server and install a proxy (either apache + mod_proxy or squid, doesn't matter). I'm looking for ideas on how to deploy this for my needs so I can then figure out how to set it up accordingly. Some ideas I've had were to setup two proxies, and have them talk to eachother through this vswitch in promiscuous mode, but it seems like alot of work. Another idea is a dual-homed proxy, but I've never seen/done that before so I'm not sure how doable it is for what I'd like. I am OK with setting up a second vswitch in promiscuous mode to facilitate this if need be, but I cannot put the vswitch on the lan (which is used so my browser would communicate with the proxy) in promiscuous mode. Any ideas are welcome.
