  • Windows 7 Automatically Connecting To Unsecured Wireless Networks On Startup

    - by Xtend
    Most of the questions on this topic related to folks connecting to somebody else's wireless network when their own was available and could remedy the situation by going to their connections and unchecking the "connect automatically" box. See this: " Avoid automatically connecting to wireless network on windows 7 " as an example. In my situation, I've noticed that Win 7 will automatically connect to any unsecured wifi network - even if I have never connected to it in the past. If I am traveling and boot Win 7, it will start and connect to what appears to be the best signaled unsecured network without prompting me for confirmation (note: in the above link, "Naveen" seems to have same problem). Obviously, that is a security concern to me. Further, when I open "Network and Sharing" and "Manage wireless networks" the network is not displayed (probably because I labelled it a public network). Again, these are new, never connected with before, wireless networks. I always promptly disconnect from them but don't want to have to be on constant guard for an auto connection to a malicious network. This began about a month ago, as I recall, Win 7 did not behave like this in the past, I didn't monkey with wifi settings, and don't use a 3rd party connection manager. I did have to download some internet security certificates for army website access but I don't think that should mess with network settings. Any ideas how I can tell Win7 cease automatically connecting to networks or, at least, to prompt me for a confirmation before connecting?

  • Office365 Exchange: Cannot open shared two calendars in Outlook

    - by Mark Williams
    The problem: Outlook won't open the calendars on another user's mailbox and and a room mailbox, even when users have permission. Note: This problem is affecting more than one account on more than one machine. So I have a room mailbox and a personal mailbox on Exchange, both with shared calendars. There is a security group called "Scheduling Users" that have editor rights on both of these calenders. The room mailbox was created using PowerShell, per the instructions posted online (http://help.outlook.com/140/ee441202.aspx). Sharing worked on both of these folders initially. Users can still access these folders using OWA. So on to the problem. When users try to open these calendars in Outlook they receive one of the following messages. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance. Cannot open this item. Cannot open the free/busy information. The attempt to log on to Microsoft Exchange has failed. What I have tried so far: Resetting the permissions on both of the mailboxes. I deleted the security group permissions on both mailboxes, applied the change, then waited a bit and gave the permissions back. Deleted the OST file of the shared calendar from the Outlook data directory That is all I have been able to find online. Any thoughts? I have been going back and forth with the Office365 support folks for a while and they seem stumped too.

  • Lots of strange IP addresses in my Windows Firewall logs. Concern?

    - by gmoore
    Was trying to debug a Samba sharing issue with Mac OS X so I turned on logging for my Windows Firewall. I didn't expect a lot of conections but the thing filled up quickly. Here's a sample: 2009-12-21 08:49:32 OPEN-INBOUND TCP 192.168.0.4 192.168.0.3 56335 139 - - - - - - - - - 2009-12-21 08:49:33 OPEN-INBOUND TCP 192.168.0.4 192.168.0.3 56337 139 - - - - - - - - - 2009-12-21 08:50:02 OPEN UDP 192.168.0.3 68.87.73.242 1389 53 - - - - - - - - - 2009-12-21 08:50:02 CLOSE TCP 192.168.0.3 212.96.161.238 1391 80 - - - - - - - - - 2009-12-21 08:50:02 OPEN UDP 192.168.0.3 68.87.71.226 60290 53 - - - - - - - - - 2009-12-21 08:50:02 OPEN TCP 192.168.0.3 212.96.161.238 1391 80 - - - - - - - - - 2009-12-21 08:50:02 OPEN TCP 192.168.0.3 212.96.161.238 1393 80 - - - - - - - - - 2009-12-21 08:50:04 CLOSE TCP 192.168.0.3 212.96.161.238 1393 80 - - - - - - - - - 2009-12-21 08:50:41 CLOSE UDP 192.168.0.3 192.168.0.4 137 50300 - - - - - - - - - I can pick out the local IP addresses (192.168.0.3 is my Windows XP machine, 192.169.0.4 is Mac OS X) as I debug the Samba issue. But some of the others resolve to Comcast (my ISP) and others resolve to weird hosts like van-dns.com and navisite.net. It doesn't look like any connection sent/received any bytes. I used the reference here: http://technet.microsoft.com/en-us/library/cc758040%28WS.10%29.aspx. Is it a cause for concern?

  • Having problems VPN'ing into our Windows server network.

    - by Pure.Krome
    Hi folks, When two people (on their notebooks) try to VPN to our office, only the first user gets a connection. the second user always times out. Is it possible for VPN to allow two or more people, using / sharing the same EXTERNAL PUBLIC IP to connect/authenticate? Now for some specifics (cause those two statements are very broad). I'm not in the IT Dept. I'm a developer. Our IT Dept don't really care (sigh) so it's up to me to fix this crap. Our office is all Microsoft shop stuff - servers and clients. We also have a firewall (watchguard brand?) and some other crazy setups (yes i know, it's very vague :( ). So i'm wondering - is it possible for multiple users, from the same public IP, to connect via VPN to a windows server? i'm under the impression - yes. But it is possible that this only happens when the clients (who are all behind the single, public IP .. otherwise they will have their OWN ip's) need to have UPnP running or something? this is killing me and i need to start asking the right questions cause these guys don't know what they are doing and i can't work without this happening. I know this is a vauge question with so many 'if-what's-etc' but maybe some questions/suggestions from you guys might start to lead to solving this problem. EDIT: Network Connection: WAN Miniport (PPTP)

  • Unexpected multiple network connections on Windows Vista

    - by Jens
    My Network and Sharing Center shows multiple connections to the internet, where only one is expected: My internet access works fine, but since the "Unidentified Network" is set to public after each boot, sharing and network discovery don't work as well. Similar questions on Google point mostly to the Bonjour service, but I am sure that this is not, and never was, installed on this machine. So: How can I get rid of the unidentified network?

  • When should NTPd broadcast/broadcastclient be used instead of client/server or peer modes?

    - by Luke404
    The NTP deamon if often used in its simplest mode, which is client/server: you specify one or more server directives in your ntp.conf and your clients will use those servers. In addition to that, when you run your own NTP servers, it is good practice to peer them together, so if one of them looses connectivity to its upstream servers, it will get time from its peers. But NTPd can also work with broadcast and/or multicast distribution of time data, with the documentation stating: broadcast and multicast modes are intended for configurations involving one or a few servers and a possibly very large client population The documentation also says elsewhere: It is possible and frequently useful to configure a host as both broadcast client and broadcast server. A number of hosts configured this way and sharing a common broadcast address will automatically organize themselves in an optimum configuration based on stratum and synchronization distance. I can see one obvious administrative benefit: you don't have to manually specify and update your list of NTP servers in the clients ntp.conf, so to me it looks tempting to use broadcast mode even for a small client population (say 5+ clients with 3~4 servers). I expect network traffic to be a little higher with broadcasts instead of client/server associations, but given the usual gigabit ethernet LAN the impact should be negligible unless you have a very very large number of hosts in the same broadcast domain. At the end of the day, when should broadcast mode be used or avoided? Are there pros and cons I haven't seen?

  • Can a Windows Domain play along with a Hosted Exchange service?

    - by benzado
    I'm setting up a computer network for a small (10-20 people) company. They are currently using a Hosted Exchange service they are totally happy with. Other than that, they are starting from scratch (office doesn't even have furniture yet). They will need some kind of file sharing server set up in their office. If I set up a machine as a file server and nothing more, users will have three passwords to deal with: local machine, file server, and email. If I set up a Domain Controller, identities for local machine and file server will be the same. But what about the Hosted Exchange server? Must the users have a separate email password, or is it possible to combine the two? (I realize it might depend on the specific hosting provider, but is it possible?) If not, it seems like I have these options: Deal with it: users have a separate email password. Host Exchange on the local server: more than they want to manage in-house? Purchase a hosted VPS, make it part of the domain, and host Exchange there. (Or can/should a VPS be a domain controller?) I realize I have a lot of questions in there. The main one: is there any reason to use a Hosted Exchange service if I'm setting up other Windows services?

  • Windows Vista/7 dropping Mac Server share points

    - by Hooligancat
    My Windows Vista and Windows 7 clients are having problems maintaining access to SMB shares on a Mac server. The initial connection to the server appears to be OK, as the Windows clients can see all of the server share points. However, the client randomly drops a couple of the server share points although the clients can still see the server. For example. If I have the following share points on the Mac server: Share A Share B Share C Share D Share E The Windows client can see these shares most of the time and can access them most of the time. But randomly a couple of the shares will just get dropped or go missing from the Windows client's ability to view them so I end up with something like: Share B Share D Share E All the share points are established int the same way with the same permission settings. My Mac OSX Server is set up with the following for SMB: SMB sharing enabled Standalone Server Workgroup of `CORPORATE` Allow Guest Access = YES Client connections limit = 100 Authentication: NTLMv2 & Kerberos and NTLM Code Page is Latin US (437) This is a workgroup master browser WINS registration is set to Enable WINS server (tried with setting off) Enable virtual share points for homes YES I noticed in my SMB file service log that the clients appear to connect OK, but I get the following error which implies a reset by either the server or the client: /SourceCache/samba/samba-187.9/samba/source/lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.0.99. = Connection reset by peer I am a bit stumped as to a direction to turn to try and get this to resolve. Continued attempts to access the server from the client will reconnect to the share points, but they inevitably get dropped again in the near future. Any and all help much appreciated.

  • Using Samba to share a folder from a Linux guest with a Windows host in VirtualBox

    - by AmV
    I would like to share a folder from a Linux Guest with a Windows host (with read and write access if possible) in VirtualBox. I read in these two links: here and here that it's possible to do this using Samba, but I am a little bit lost and I need more information on how to proceed. So far, I managed to set up two network adapters (one NAT and one host-only) and install Samba on the Linux guest, but now I have the following questions: What do I need to type in samba.conf to share a folder from the Linux guest? (the tutorial provided in one of the links above only explains how to share home directories) Are there any Samba commands that need to be executed on the guest to enable sharing? How do I make sure that these folders are only available to the host OS and not on the Internet? Once the Linux guest is setup, how do I access each of the individual shared folders from the Windows host? I read that I need to mount a drive on Windows to do this, but do I use Samba logins, or Linux logins, also do I use localhost? or do I need to set up an IP for this? Thanks!

  • Mac, VNC and multiple monitors

    - by MarqueIV
    I asked a similar question here before but apparently I wasn't as clear as I had expected by the responses. That said, I'll try again. I have a Mac Pro with quad monitors which I would like to access remotely. I've been using VNC for this (either via screen sharing or a dedicated VNC client), which works, but the VNC protocol matches the physical layout/resolutions of attached monitors. One of the things I like about Microsoft's Remote Desktop (Terminal Server) client is that when you connect, it blanks out the local screens and sets the resolution to a client-specified setting. In other words, when natively running Windows, even though I'm running a physical 30" monitor flanked by 2 24" monitors as well as a 21" Cintiq monitor, I can set the Remote Desktop resolution to match my notebook's screen giving me a native, single-monitor configuration. As soon as I disconnect (and you log back in locally), the desktop un-blanks and the resolution resets back to the four physically attached monitors. Again, VNC works and yes I know I can use 5901, 5902...n to attach VNC to a specific monitor as opposed to the entire desktop, but I'm still at the mercy of trying to look at a 2560x1600 resolution on a 1280x800 screen. I'm left with either scaling (everything's too small) or panning/scrolling (it's like playing hide-and-seek with your documents!) SO... anyone know of any Mac-based remote software (client and server) that will let me connect to my Mac Pro and reset the resolution by the client, just like you can in Windows, or am I SOL?

  • While using an ntfs smb share for mac users, do symbolic links and extended attributes work?

    - by scape
    We have a majority of mac users but we'd rather support their file sharing using a Windows server with an ntfs drive, or at least a Linux server with ext3. We've had trouble, much trouble, utilizing the OS X server software and after the years are now looking to abandon it. What's mostly holding us back is the fact that the mac users very often utilize symbolic links and other special features that exist for an HFS+ partition. The shared locations are mostly primary storage and not just used as an archive storage location. While there is an option to create symbolic links under ntfs, I'm curious if there is anything I need to look out for if I were to move the files over to a new partition that's hosted from a Windows server from the HFS+ partition; in addition, how well creating a symbolic link from a mac might work. I am also worried about windows backup software and if it will ruin these special sym links, and how placing permissions on sub-folders will work. Alternatively I could remotely backup the files using a mac and Bru, nonetheless I still want to get away from mac server for hosting the shares.

  • Desktop Provisioning for a Small Linux Software Development Team

    - by deakblue
    Goal: Get a small team using a standard development image rather than 4 software devs setting up their own environments. Why: it takes a day or days to install a distro, build-specific libraries, tools like editors and IDEs, mysql, couchdb, java, maven, python, android-sdk, etc. It's a giant PITA that when repeated 4 times by 4 developers (not sys admins) wastes time and generates annoying divergences that crop up later (it-builds-on-my-box syndrome). There's no sharing of productivity, settings, tricks, scripts, set-ups. Some of this is helped by segregating the build systems into headless virtualbox images. This doesn't really address tooling though or the GUI-desktop dev that needs doing. So I see three basic strategies, ghosting, virtualization, and finally creating a kind of in-house linux distro (I guess Google does something like this). The target dev environment is based on Debian OpenBox and must allow a mix of 3rd gen Core i7 notebooks 8GB-minimum to work both single and multihead. Important, the lappies are not the same, but a mix of 2012 macbooks and PCs. So: virtualization: is doing all of your work within a VM, like VirtualBox, practical on this hardware or annoying. ghosting: will laptops from different manufacturers make this impractical. DIY distro: short of scripting a bunch of package installs, I don't know if there's any "distro-maker" that could keep this from being an epic project of scripting package installs. So any advice?

  • Replacing HD in an MacOS 10.6.8 server caused all shares to fail

    - by Cheesus
    I'm hoping someone might have a helpful suggestion about this problem. We have 2 MacOSX servers available for file sharing. (quad Xeons - 2GB RAM, both 10.6.8), No.1 is an Open Directory Master with 50+ user accounts, No.2 has only 2 local accounts (/local/Default) and looks at the OD Master for all user accounts (/LDAPv3/10.x.x.20/) Both servers have 3 internal HD's, The boot volume with only Server OS and minimal Apps. A 'DataShare' HD (500GB) and a backup drive (500GB). After upgrading the DataShare HD in Server No.2 from a small internal HD (500GB) to larger capacity (2TB) drive, users are unable to connect to shares on Server No.2. Users get an error "There are no shares available or you are not allowed to access them on the server" The process I followed was to use Carbon Copy Cloner to create an exact copy of the original data drive (keeps all ownership data, UID, permissions, last edit date and time). Everything booted up ok, no indication there was any issues. (Paths to the sharepoint look good) Notes during troubleshooting - Server1 is operating perfectly, all users can access shares and authenticate etc. - I've checked the SACL (Server Access Control List) settings is ok. - On Server2 in the Server Admin' app, I can see all the shares listed ok. The paths seem valid, I can disable / reenable the shares, no errors. - On Server2 'workgroup manager' lists all the accounts from the OD Master in the LDAP dir view. All seems fine from here. Basically everything looks normal but no file shares on Server2 can be accessed from regular users.

  • Files being rolled back on server 2008 R2

    - by Gary
    I've got a weird situation occurring on my dev server. Randomly, and for no reason that I can see, files are being rolled back to an earlier version! This has happened twice now - the first time I assumed I'd done something wrong somewhere, restored the file I was after from a backup and gave it no further thought. The second time, just now, it happened to a folder containing just a few files that I was working on - suddenly all the changes I'd made over the last day or two were gone! (I know, commit more often, ay?). Thankfully I have a daily backup and so have recovered my files, but I'm very concerned about this and need to understand how and why it's happened. The only change made between file states is that I enabled sharing on a completely unrelated folder. I'm developing an app on Railo, which is running on Tomcat. The code was all fine and in c:\websites\appname. I shared the 'Railo' folder, which is c:\railo in order to allow my IDE access to the logs generated by the app (contained in c:\railo\tomcat\logs) and when I reloaded the app, the code was reverted to a few days ago! I'm at a complete loss here. Can anyone point me in the right direction? Thanks.

  • Basic connectivity issues between Win 7 and XP mixed wired/wireless network.

    - by Pulse
    Setup: Windows 7 x64 Ultimate desktop hard wired to Asus WL500gp router (WL500gpv2-1.9.2.7-d-r1445 firmware) Several Bridged VirtualBox VM's running XP, 7, ubuntu server 10.04, Mint 9 and SuSE 11.2 Win XP Pro SP3 notebook with D-Link Airplus wireless network card. No firewall or other security software currently running on either platform (at least for the duration of the test) Situation: Router is acting DHCP server Clients are receiving correct addresses and additional parameters Internet connectivity is available from all clients Windows 7 sharing is set to Network type = work (not home group) NetBT is disabled on all clients using smb over TCP What I can do: I can ping the router and internet addresses from the wireless XP notebook I can ping the Win 7 desktop and any VM from the XP wireless notebook I can ping all devices from the router All VM's and 7 can ping each other and the router as well as Internet addresses What I can't do: I cannot ping the XP wireless notebook from either The Win 7 desktop or the VM's it alwats returns a destination host unreachable. Tracert resolves the name or the XP notebook but also returns a destination host unreachable. From the above it would seem that something is blocking connectivity in a single direction (from the Win 7 box to the Win XP notebook) only but the router can ping the XP notebook. Some fresh input would be most welcome, as this is beginning to drive me batty. Thanks

  • Super slow opening my downloads folder

    - by Mark
    I have an exe file in my download folder that I half downloaded through utorrent (it's not piracy, a legit file from people who use bittorrent to distribute large files). I think I tried to open it while it was still sharing, that is, did not stop the upload. That actually froze my computer. When I restart in utorrent I set the file to be deleted. Unfortunately even though utorrent doesn't see that file anymore, it's still visible in my download folder. Whenever I try to open my download folder it literally takes 10 minutes or more. It opens, but is empty and the blue progress bar needs a long time to complete. After completion I can use the download folder normally, but opening and closing things in that folder takes a long time. I see the exe that I tried to download. I tried to delete it. But it was taking so long 30+ minutes that I eventually just hit cancel. That doesn't even work, and it was slowing down the computer. Couldn't figure out how to stop the delete so I just pulled the plug. Should I just forget about that dl folder and set a new one? Is there something I can do? Thanks.

  • virtual machines, dual booting and data disks on SSD

    - by stevemarvell
    This is in planning, so if I've got the strategy wrong, please let me know. There are multiple questions here, but I think they all degenerate to the same answers. The hardware is a laptop with a single SSD. I'm trying to not lose the performance of the SSD. I plan a native dual booting Windows (plus cygwin) and Linux machine which is my BYOD and represents the development environment. I keep the codebase on a shared partition (though sometimes this is an external thunderbolt SSD) which can be natively "mounted" by whichever OS is in operation. I boot into one or the other environments depending on the task in hand. Sometime I have to develop with windows tools, but generally, Linux is my preferred development environment. It would be ideal if I could VM the other OS and run either in either. I'm going to assume, because I've not found a sensible VM based solution, that I have get samba involved to share the code partition between VMs. Is this going to blow my SSD performance in the VM? The client also supplies me with a VM for the target environment, usually linux. This is not often suited to development and is used for testing only. I normally keep two copies of this, one as a sandbox and one which I deploy to using the client's preferred method. I keep these VM snapshots on the shared partition. The latter is interacted with over the network and so has no disk sharing requirements. However, it would be useful for the sandbox to be able to "mount" the code base from the natively running OS. Is this samba or nfs again, depending on the native OS? Am I missing a trick which allows this to all work smoothly with all four environments running at once without loosing the SSD performance?

  • Find routers IP address on the other side

    - by corsiKa
    Here's the basic setup of my network In this diagram: 1: The internet c: cable 2: Wireless router w: wireless connection 3: A win7 box with internet connection sharing enabled 4: A wireless router, but I'm only using its LAN capabilities to connect box 5 to the internet. 5: A win7 box, the computer I'm using to make this post. So its internet works just fine. Now if I'm on box 5, and I ping 192.168.1.1, I hit 4. If I'm on box 3 and I ping 192.168.1.1, I hit 2. Now obviously box 3 does not think 4's IP address is 192.168.1.1, or I wouldn't be able to connect to the internet. Okay, now that you know as much as I do about my network, here's my question: If I was on box 3, how would I determine the IP address of 4? Basically I'm running a webserver on box 5 and want to access this webserver on box 3 and other boxes. So that's the end goal. If there's other information there that can help, I'd appreciate it. Thanks!

  • Ask the Readers: How Many Monitors Do You Use with Your Computer?

    - by Asian Angel
    Most people have a single monitor for their computers, many have two, and some individuals enjoy “3 monitor plus” goodness. This week we would like to know how many monitors you use with your computer. Photo by DamnedNice. A good majority of people have a single monitor that they use with their computers and that single monitor serves their needs very well. It could be that these individuals do not engage in a heavy amount of work or play on their computers…they just need to do the basics like checking e-mail, using I.M., working with photos, etc. Another possibility is the use of virtual desktop software such as Dexpot, Yodm 3D, or Sysinternals Desktops on Windows systems. Linux systems such as Ubuntu already have that wonderful multi-desktop functionality built in. The wonderful part about virtual desktops is that a single monitor can feel equivalent to a small army of monitors. The ability to separate your open windows into “categories” and spread them out across multiple desktops is definitely nice. With each passing year dual monitor setups are becoming more common. Having twice the screen real-estate visible at the same time can be extremely convenient when you are multi-tasking. Perhaps you like to monitor your system’s stats and an e-mail account on the second monitor while working with software on the first. It certainly beats having windows popping up and down on your screen constantly while keeping on top of everything! Next we have the people who have three or more monitors in use with their computers. This may be a result of the type of work they do, an experiment to see if multiple monitors are right for them, or the cool, geeky factor that comes with having all those monitors. Needless to say these individuals can induce a good amount of envy and/or inspiration in the rest of us when we see their awesome setups. Are you perfectly content with a single monitor?

  • Using the same Windows 8 Upgrade installer on multiple PCs

    - by Karan
    As per this article: You may transfer the software to another computer that belongs to you. … You may not transfer the software to share licenses between computers. But what if I have a bunch of PCs with a mix of XP/Vista/Windows 7? Can I purchase either the Windows 8 Pro Upgrade $40 (download only) or $70 (DVD) version (both of which come without a key) only once and use it to upgrade all the PCs? Since I'm not sharing the license and each PC has its own valid genuine license, it should be allowed, right, or is it illegal? Even if they want people to shell out $40/$70 for each PC, how would they enforce the use of the installer/media on only one PC each? EDIT: I have been given to believe by a source that the installer will only check for the previous OS' key, which is what is confusing me (I have never purchased an upgrade version before this, only full retail or pre-installed versions). Is this true or will I need to enter two keys to make the upgrade work, one for the previous version and then one for Windows 8? If the latter is the case, then the issue is solved since obviously the same Windows 8 key will not be valid for multiple PCs.

  • How to connect the virtual networks of vmware guests running on different hosts?

    - by gyrolf
    In a test setup, we are running several virtual machines on a single vmware workstation host. All virtual machines are connected via a "host only" network. This runs fine up to 2 or 3 virtual machines (depending on the host hardware). To allow more virtual machines, we want to use more host machines. Details about the environment and applications: Host PCs are running Windows XP in a corporate intranet. VMware used is Workstation 6.5 Guests are running Windows Server 2003 All guests act as Web Servers One of the guests additionally acts as Windows File server, offering shared folders for the other guests to connect to. Restrictions: VMware guests shall not be visible from the intranet. Changes to the host PC are restricted by corporate policy. In the virtual network, no domain controller exists. All virtual machines are member of the same workgroup. Running the virtual network as NAT is possible. Port forwarding might be used if it does not conflict with ports used by the host PC. Looking for a solution, I found hints about using router or vpn software on the hosts, but without any details how to setup. (I found a similar question Sharing the network between 2 VMware hosts, but the answer was not sufficient for me.)

  • Does ICS modify windows firewall policies in the registry?

    - by insipid
    I had a host machine I wanted to enable ICS on. First I realized that doing so was not possible until I enabled the Windows Firewall. Once I enabled the firewall and set up ICS, I noticed due to group policy I could no longer disable the firewall. Also, any ports I tried to open seemed to be ignored. Although nothing seemed to be configured when I used the mmc snap-in to view local computer policy, when I checked the registry I noticed several policies set there in HKLM (such as disabling AllowLocalPolicyMerge). I was able to remove the policies from the registry and my open ports worked, but they were eventually re-added without my input. The network I am sharing the internet from is an "unsecured" wireless network with an authentication page, is it possible that this is causing those policies to be set? Did ICS set those policies? When you go to the properties of the ICS enabled adapter and go to the ICS settings it takes you to a tab called services where you can add and remove "services running on your network that internet users can access". Is this related to the windows firewall?

  • Memory overcommitment on VmWare ESXi 5.0

    - by Tibor
    I would like to understand better the possibilities of VmWare ESXi memory overcommitment. I've read this paper from VmWare, so I am familiar with general concepts, such as hypervisor swapping, memory balooning and page sharing. It seems that a combination of these techniques allows for quite a large degree of overcommitment. However, I am not sure. I am deploying a virtual test lab comprising of 4 identical sets of virtual servers and workstations and a couple of virtual router instances. Overall, I expect to be running around 20 virtual machines with Windows XP, Windows 7 and Ubuntu for workstation hosts as well as CentOS and Windows 2008 Server instances for servers. The problem is, however, that the host machine only has 12GB of RAM and I don't have an option to stuff in some more. I would like to know what is the best option to configure hosts in order to achieve reasonable performance within the constrains. I have these two options: Allocate as little as possible of RAM to each virtual machine. Allocate an extraordinary amount (such as 4 GB per instance) and let the baloon driver do the rest. Something else? Which would work better? Machines will mostly be idle, so I don't have any major performance expectations, but they should run reasonably smoothly nevertheless.

  • Assigning cores to VM in vSphere

    - by user114933
    Complete vSphere newbie here... Background: So, I have a 12 core machine with 24 VMs on it. Currently, all the processing power is shared between these VMs equally. The question: Can I configure one VM to be given two CPU's worth processing no matter what's happening on the other machines? My Research: I tried two things in vSphere... I set the reservation and limit on one VM to equal the same as two cores. To test if my objective was being reached, I measured the time it would take to gzip a file when other VMs were running nothing and when other VMs were running CPU intensive operations. I expected the time to gzip the file would be the same because this VM gets priority for some processing. Unfortunately, the time taken to gzip the file when other VMs were running something was significantly more than when other VMs were not running anything. I tried setting the Hyperthreaded Core Sharing mode to Internal hoping that this would mean that my VM would get at least an entire core to itself. This did not work either. Thanks in advance!

  • Cisco configuration for public library internet

    - by AlternateZ
    I'm a C/C++ computer programmer turned IT support guy working for a public library. My day is usually spent helping random grandparents learn how to use email, so my networking knowledge is limited to what I can glean from google. Here's the situation. We have a public library with 20 PCs on a LAN and also public wifi access. Previously we were running all of this on 1 ADSL connection and people complained about low speeds. We hired a networking company to set up a Cisco dual-WAN router for us, and purchased an additional ADSL connection. The intention was to give the LAN PCs a guaranteed amount of bandwidth each, and then let the wifi users split the rest. The results were far worse than what we expected, and all we got from the company was excuses and they've since washed their hands of us. During busy periods, net performance on the LAN PCs are so poor that attaching files to gmail etc often times out and fails - far from the "guaranteed amount of bandwidth each" that we hope for! Sometimes it feels like performance is worse than before when we had 1 ADSL link and an unconfigured router? Anyways, surely this is a problem encountered a million times over across the world? (Sharing internet across many users effectively.) What are standard solutions for something like this? I admit to not even knowing the right jargon to google for (load balancing?) I'd appreciate any links to resources/guides that might help me get a better understanding of the problem/solutions, and perhaps some stories of your own experience in solving similar problems. This will help us evaluate and negotiate with network consultants in the future. If its relevant, our router config contains a section "policy-map" with "bandwidth percent" for each class of user (LAN, wifi), and "fair queue".
