  • OS X Server - setting up a share for network home directories + fast user switching

    - by sohocoke
    I'm nearly finished setting up my Open Directory master to allow users to be managed centrally and logged in on any of the client machines at home. I found discussion suggesting that using an AFP share for the 'Users' automount would result in network users (cf. users defined locally, or Portable Home Directory users) are unable to use fast user switching, as the first user logging in would trigger the automount and mount the 'Users' share with his permissions, preventing further users from using the mount. I've also found some suggestions to configure autofs such that the 'Users' share is mounted prior to any user logging in, but not great amounts of details along these lines. I'd greatly appreciate some instructions to set up autofs - ideally, on the OpenDirectory server rather than each client's etc/fstab or equivalent location, so that it isn't required per every client machine - to get fast user switching working with network users.

  • Diagnosing extremely slow network operations.

    - by Chris Becke
    The network: * A windows 7 PC with 2 NICs - one connected to an old style ethernet hub - the other to the internet - with internet sharing enabled * An Apple iMac connected to the hub, successfully utilizing the ICS to access the internet. My problem: Using the Mac, copying from the internet is fast. However, if I connect to a SMB: share on the Windows 7 PC and try and copy anything a few kb the copy operation is appallingly slow with my network card using the Windows 7 control panel showing ~.1% utilization. The NICs are 100Mbs and show a 10x larger throughput (now ~1%) if I download large files over the internet using the Mac. WTF?

  • Setting DNS suffix for multiple network adapters in a VM

    - by arun_bh
    Is there a way to set the DNS Suffix for multiple network adapters in a VM using the sysprep file? We are trying to setup Windows 2003 VMs with 2 network adapters. In the one adapter case the sysprep we are able to set the suffix using DNSDomain. But this doesnt work in the 2 adapter case. The The VM is setup corrently though without any issues but one of our apps relies on the DNS Suffix value to work correctly. Thanks in advance.

  • IP Connflict on network

    - by PSU_Kardi
    I keep getting an IP conflict on my home network and can't figure out why. I'm running a Belkin-N wireless router that has an Ethernet connection to my 360 and a wireless connection running to my laptop. It's WPA2 encryption and I have a nice password on my router consisting of letters , numbers and special characters. But for some reason I keep getting IP conflicts at night time...By the time I look into the problem I don't see anyone else on the network. Is my router giving me false positives?

  • Mac OS X Server mobile account VS Time Machine Network Backup

    - by elhombre
    I am installing a Server @home to manage the mac client's of my family. First I wanted to make time machine Backups over the internal network to an external Hard-drive which is connected to my Mac OS X Server (10.6) but when I read about the mobile accounts and it's synchronization features I got a little bit irritated what the differences between the two Services are. So where are the differences between a mobile account and a Time Machine Backup which is made over the network? Can the synchronized mobile Account be backup to an external Harddisk, if yes, how?

  • Loss of wireless network connectivity when playing video via HDMI cable

    - by Jeff Fohl
    Hi Folks - New to Super User, so I hope this question fits in with the guidelines. Very strange problem I am having, and I am at a loss as to how to continue troubleshooting this one. The basic problem is that when I attempt to watch streamed video on a particular display device (an Optoma HD180 projector), my network connectivity drops like a stone to barely measurable levels. This is my setup: I have a Dell H2C 730x running Windows 7 64bit. This particular computer has two ATI Radeon HD 4800 video cards. I have two Samsung 22" monitors connected to one card, and an Optoma HD180 digital projector connected to the other card via an HDMI cable. My internet connection is normally a reliable 6Mbps. The problem I am having occurs when I stream video (or even just browse the web) on the Optoma Projector. When I do this, my internet connection drops to practically zero (just a few kilobits per second). When I move the browser away from the projector, and over to one of my Samsung monitors, the internet connection comes right back. Note that the Optoma projector is on and enabled as a third monitor all this time. I can move the mouse around on the projector without triggering the problem. I tried pinging my router when I was playing a movie on one of the monitors, and I get a 1 millisecond response. However, when I have the movie playing on the Optoma projecter, pinging the router gives me response times in the hundreds of milliseconds, or times out completely. So, it clearly is something local to my machine - and not some sort of throttling occurring down the line. I would think that it is possibly something to do with the HDMI driver conflicting somehow with my network driver (which is a USB-based wireless connection). This one has me really stumped. Anyone have any ideas? EDIT: I am now leaning towards the possibility that the HDMI cable is somehow interfering with the wireless network, when large amounts of data are being pushed through the cable. Is this possible?

  • Getting network interface device name in powershell

    - by Grant
    I needed a powershell 2 script to get the name and device name of each interface like it is shown in network connections in control panel. Should be easy... $interfaces = Get-WmiObject Win32_NetworkAdapter $interfaces | foreach { $friendlyname = $_ | Select-Object -ExpandProperty NetConnectionID $name = $_ | Select-Object -ExpandProperty Name } However, $name comes back as "Broadcom BCM5709C NetXtreme II GigE (NDIS VBD Client)", whereas in control panel it shows "Broadcom BCM5709C NetXtreme II GigE (NDIS VBD Client) #69", because there are multiple cards. I can't find that number anywhere in the properties. How can I get both the Name and Device Name, exactly as shown in Network Connections, in powershell 2 on windows server 2008 r2?

  • how to change interface ip in ifconfig with /etc/network/interfaces

    - by user2478348

  • Does Cisco anyconnect replace original network connection session?

    - by Stan
    When using Cisco anyconnect VPN, it seems the existing network connection is still going through old connection session (Is there any way to find out)? The reason is because when using Cisco VPN client connect to gateway, usually the Messenger Live, Skype will be disconnected and requires to reconnect. But using anyconnect doesn't need to reconnect. So I am guessing if those old sessions still go through original network connection. Which means, both connection is existing at the same time. Take my case for example: connection 1: wireless NIC - cable modem - my cable ISP - internet connection 2: anyconnect - wireless NIC - cable modem - my cable ISP - VPN gateway - internet Am I correct? Is there any way to check this? Thanks.

  • Setting up Kerberos SSO in Windows 2008 network

    - by Arturs Licis
    We recently introduced Kerberos (SPNEGO) Single Sign-on in our web-portal, and tested it on a Windows network with Windows 2003 domain controller. Now, trying to test it on Windows 2008 R2 controlled network, SSO just doesn't work due to defective tokens. Up to the moment I was pretty sure that there's something wrong about environment and that were NTLM tokens. We double checked IE settings etc, but nothing helped. Then we checked the following settings for both users (logged on a client test-machine, and the one used as a Service Principal): This account supports Kerberos AES 128 bit encryption. This account supports Kerberos AES 256 bit encryption. .. and error message changed to ' GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256CTS mode with HMAC SHA1-96 is not supported/enabled) It makes me think that Internet Explorer receives Kerberos tokens at all times, and there's just some configuration missing, or it was ktpass.exe to be incorrectly executed. Here's how ktpass.exe was invoked: C:ktpass /out portal1.keytab /mapuser USER /princ HTTP/[email protected] /pass *

  • Add a netbook to an existing Windows XP home network

    - by GorillaSandwich
    I've got a home network set up with a couple of Windows XP computers. I'm now trying to add our new netbook to it - also running XP. (The goal is to share files and a printer.) I have run the Network Setup Wizard and made sure that the workgroup name is the same as the others, and have rebooted several times, but whenever I try to 'view workgroup computers,' the only one on it is the netbook. I have a Windows XP CD, but the netbook has no drive. The wizard has some options for floppy disks, but that's useless to me these days. What is this wizard actually trying to do, and can I do it manually? Surely it can't be this hard.

  • Speed up file access on home network

    - by kurasa
    I have 2 PCs (Windows 7 Ultimate) and a Mac running Windows 7 using vmware fusion on my home network tied together using WRN1000 NETGEAR Router On one of the PC's I have a set of file (MYOB .myo). These use a data source to access the data in the files. Operations (reading,writing) to the .myo on the PC which hosts the files is fine but the other 2 it is painfully slow/unreliable and I am wondering what I can do to speed this up. Some ideas I have are 1. Turn off the Windows firewall on all the windows installations on the home network 2. Buy another router. Specifically a router which I can connect a USB flash drive on the back where I can put the .myo files and all the PC can access the files from the USB flash drive on the router (does this speed things up?) Any advice greatly appreciated on how I can speed up this access to data

  • See network computer description in Explorer

    - by John Gardeniers
    When viewing the list of network computers in Windows Explorer on a Win 7 machine there appears to be no way of readily seeing the description field, which makes that pretty well useless. I believe this problem started with Vista but I'm seeing it for the first time because I was fortunate enough to skip over Vista. We're currently rolling out Win 7 on new boxes and although I'm changing the naming system to something more sensible, the old boxes have names such as FWS01, FWS02, etc. Managing a network of computers with such names is made more difficult when you can't readily see who's machine each one is. Googling the problem brought up a workaround involving creating a shortcut on an XP machine and copying that to the Win 7 box but that's a long way from ideal. Is there some kind of hack that can be applied to machines, the operator of which needs to be able to see the description field?

  • 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?

  • Steps to make sure network is not blacklisted...Again

    - by msindle
    I have an interesting issue. I have a client that just got blacklisted due to spam being sent out over the last 2 days. I have my firewall configured to only allow mail to go outbound on port 25 from our mail server (Exchange 2010) exclusively and I have verified that there are no open relay's on our transport rules. We are running Vipre Business and after running deep scans with updated definitions all computers come back clean. I ran a message tracking report on our Exchange server that shows all mail sent via the mail server over the last couple of weeks and didn't see anything malicious or out of the ordinary. I have also verified that there are no home devices or rouge computers on the network. For all practical purposes it appears that the network is clean, but we still wound up on 5 or 6 blacklists...Where should I start looking next? Is there a "best practices" guide that can help eradicate this issue? Thanks in advance! msindle

  • Some domain names not resolving on local network

    - by Solignis
    I am not really sure where to start with this one... I have a small network setup with some linux servers (Ubuntu 11.04 Server). 2 servers are running BIND 9 (NS01, NS02), they are configured as master and slave respectively. 1 server is running Zimbra ZCS 7.1.1 (MX01), it has a private BIND 9 server running to achieve a split DNS configuration. This DNS server does not interact with the other two, it forwards queries it can resolve to the other 2 that is it. No zone transfers. Zimbra is hosting 3 domains at the moment, solignis.local, solignis.com, campbellsurvey.net. The problem From with in my network I cannot connect to mail.campbellsurvey.net. When I mean I cannot connect, I mean if I open firefox and type https://mail.campbellsurvey.net I go nowhere, the address is supposed to connect to my Zimbra webmail. But it goes nowhere, the odd thing is if I try the same task from outside of the network it brings the website up like normal. If I try to create an account in thunderbird to connect to the same server using IMAP4 or POP3 I get an error saying that thunderbird cannot find the domain name. Even the zimbra client fails too. It is like from with in my own walls that campbellsurvey.net does not exist. But if step outside I can get it work with no problem at all. I had thought maybe the problem was with the DNS server (BIND 9), so just to eliminate it as a possibility I configured a windows server I use for VMware VCenter as a DNS server to see what would happen. The result was the same, its like something is preventing connections to those domains, but I have checked various firewalls and such. I checked port forwards, etc. So I am running out of ideas I know this is not a lot of information to work from and I can give more details about certain things as needed. I am just trying to figure out what could be going wrong. Any help you could offer would be much appreciated.

  • Windows 7 wifi reports "no network access" and "no internet access" but connects in fedora

    - by rick2047
    I am running windows 7 home basic (64bit) on a Acer 5742G laptop with Atheos wifi adapter in it. Yesterday, I hiberneted my computer as I always do and up untill then the wifi was working fine. When I booted my computer up again today I started having a strange problem: It detects my wifi but after connecting to it, it keeps on oscillating between states of no network access and no internet access. I can't connect to anything (the internet or my router). I tried to reset my internet protocol stack using this fixit file. I also tried to uninstall and reinstall my network driver. Neither helped. I am using the same laptop's fedora installation right now and the wifi is working perfectly fine. Please help. Edit To add additional details, I have Microsoft Security essentials as my antivirus software and I haven't messed with the firewall or the router configurations.

  • Install a program from the network

    - by Gomibushi
    In Windows there is a place under the Control Panel called Get Programs and Install a program from the network (in Win 7 at least), possibly a slightly different name in Vista, but it was there too. The question is basically: How do you publish programs to that so users can go there and install? Bonus follow up: Is it a good way to deploy optional programs? (Compared to using GPO's.) In Windows 7 you can go to Control Panel, Programs, Programs and Features, and on the left hand menu: Install a program from the network.

  • Can a virtual mikrotik box bridge a hyper-v internal network with a hyper-v external network?

    - by mcfrosty
    I am trying to set up a Mikrotik router as a transparent firewall on my network. I got the machine working on a hardware MT box, but my boss wants the MT virtualized. I have been trying the set up where my virtual windows box talks to the Mikrotik via private or internal network on the Hyper-V host. I can get the two machines to talk, but as soon as I set up a bridge on the MT, all traffic ceases between the two. Is it possible to create a bridge for this purpose (having the MT silently in front of my firewalled server)? I could really use some help.

  • fstab mount after network initialization

    - by Philip
    I'm automatically mounting a NFS with fstab. Sometimes the mount fails because the hostname of the NFS mount cannot be resolved (getaddrinfo failed). I'm assuming that this happens because the network initialization is slower than the mounts. Is there any way to initialize the network before mounting any devices? I'm already using _netdev as a mount option but this does not help. This is my current fstab file: # <file system> <mount point> <type> <options> <dump> <pass> /dev/md2 / ext3 errors=remount-ro 0 1 /dev/md1 /boot ext3 errors=remount-ro 0 1 /dev/sda3 swap swap defaults 0 0 /dev/sdb3 swap swap defaults 0 0 connect.mygluster.net:/data /var/gluster/data glusterfs ro,_netdev 0

  • How can I use mobile network account at server so home sync works

    - by Mike Gallagher
    I would like to be able to use a mobile network account while sitting at my server. I had os x server 10.6 running on a mac mini server but recently got a new quad core iMac and want to take advantage of the extra power. My problem - I can sit at the server and log into the mobile network account but can not get it to sync back. When I attempt to sync it get error message that the afp share point is unavailable and that the files are hosted locally. My goal is to be able to use the new iMac as the server and set a user account so that it remains synced so when the account is accessed from other clients, particularly my macbook pro. Is mobile account the best route? Would an external account be a better option. Any advice or ideas of where to read up on this would be much appreciated.
