• Cannot schedule task for domain user account

  - by Filburt

  On our Win 2008 machines I can't schedule tasks for domain users because the domain name does not resolve to network name but the AD dc name. The "network name" looks like ABCDEFGE-HIJKLM and the "dc" / "name" would look like ABCDEFGE-HIJKLMN. When selecting the domain user account the account qualifier will look like ABCDEFGE-HIJKLMN\task.user. This results in an "invalid account" error. When however keeping the currently logged in user it will display ABCDEFGE-HIJKLM\current.user. Does this behaviour result from the presumable "illegal" domain name? Is there a workaround for this?

• Block (or only allow certian) incoming IP addresses on Verizon FIOS Actiontec Router

  - by jmlumpkin

  I opened a few ports to the outside of my home network so I can get into a few of my machines from outside. When checking some logs, I noticed that I was getting scanned on some ports from various other countries. I already moved my port forward to a non-standard port. I would like to be able to block specific IP's (or even subnets) from my Verizon FIOS router. There is a little bit of documentation online, but I can't find anything specific on how to do this. To start, I just want to block a specific IP. But if it is not to hard, I would also like to know how to possibly block a range of IPs. And with the inverse of this - is there a way to allow only certain IPs or range?

• Automate Windows 8.1 Enterprise upgrade [migrated]

  - by Ben M.

  I have been trying to find the necessary command line switches for automating the upgrade for my Windows 8 clients to Windows 8.1. I have the ISO extracted and I've run setup.exe /? but that doesn't tell me enough. I can't find any relevant information from search engines. Can anyone point me to some documentation or information on how to automate the upgrade so that it keeps user data, programs, etc? I know how to do it when running the installer manually, but I obviously do not wish to do that with 100+ machines.

• Bad IIS 7.5 performance on webserver

  - by Robert P.

  I have a webpage (ASP.NET 4.0 / MVC 4). On my development machine (i5-2500 3.3 8GB Win7 VS2010 SP1 Fujitsu Esprimo P700) the page performs with 160 requests/sec on devenv webserver on my machine. The page performs with 250 requests/sec on my local IIS 7.5. (uncompiled web) The page performs with 20 requests per second on a 16core 32gb ram production server (Fujitsu RX-300 w2k8 rc2 IIS 7.5). (compiled web) Why? I think it's the IIS configuration but i can't figure out whats the problem. The page runs with 1 worker process on both machines. Web garden is not an option (it helps but the app isnt compatible with)

• Running OpenVZ virtual servers within a Xen XCP vritual server? Bad practice?

  - by Damainman

  I have a 1 server with 8GB RAM and 2xQuadcore Processors. It currently has the Xen XCP installed on it, and centos6.2 x64 running on a virtual machine. I have a server control panel software that I want to use and it allows the administration via a web interface for Openvz machines. My questions are: Would this be considered bad practice? Would there be a big performance hit? Should I avoid this all together or am I going about it all wrong? Thank you in advance.

• create symlink to another machine

  - by microchasm

  Hi, I have 2 machines. Both running CentOS. Box1 is webserver with apache, php. Box2 is mysql, and file storage. The files will only be accessible from Box1 within the webapp. I'd like to somehow create a symlink or somesuch on box1 to a folder on box2 where uploaded files can be stored and retrieved. Security in mind, what would be the best way to go about linking these 2 boxes up in a transparent (to apache) way? NB: the boxes are connected directly to each other via a crossover cable; no lan access to box2. Much thanks!

• Windows 7 RDP Problem - connecting to external zone with computer names

  - by alex

  I recently installed Windows 7, all is well so far, apart from using RDP to access computers outside my domain. We use a datacenter, outside of our domain. I was using Windows Vista before (not sure if this is relevant) - I could RDP no problem to the machines (using their machine names - Web10 for example) I have changed my IP address to be the same as it was when i was using vista We use a draytek firewall - we use DMZ Host to map my IP to an external ip- which is allowed to access the datacenter I've disabled windows firewall When i try to connect in Remote Desktop client, using Web10, I can't connect, however, if I enter the actual IP address, i can. I have run out of ideas... any help is appreciated!

• Virtualbox, merging snapshots and base disk

  - by Henrik

  Hi, I have a virtual machine with about 30 snapshots in branches. The current development path is 22 snapshots plus the base disk. The amount of files is seemingly having an impact now on IO and the dev laptop I'm using (don't know if it is host disk performance issues with the 140GB total size over a lot of fragments, or just the fact that it is hitting sectors distributed across a lot of files). I would like to merge the current development branch of snapshots together with the base disk, but I am unsure if the following command would produce the correct outcome. I am not able to boot this disk after the procedure completes (5-6 hours). vboxmanage clonehd "C:\VPC-Storage\.VirtualBox\Machines\CRM\Snapshots\{245b27ac-e658-470a-b978-8e62137c33b1}.vhd" "E:\crm-20100624.vhd" --format VHD --type normal Could anyone confirm if this is the correct approach or not?

• load syntax as per file prefix

  - by Richo

  Firstly, I hope that this is the right place. I couldn't decide between here and superuser. My home directory lives in an svn repo. all my dotfiles are in version control so that I can track them across multiple machines, and they all source an unversioned .local (ie, .screenrc.local, .vimrc.local etc) which can override/make local changes to the environment in a machine specific way. The problem is that vim understands how I want to edit many of these config files, but loses it's mind when I open a .local, and honestly, I'm not really sure what it does to work out how to syntax highlight etc a file like .screenrc the pseudocode for what I'm after is: if OpenedFile.ends_with(".local") behave_as_per OpenedFile[0:-6] endif I hope this makes sense and hopefully someone can shed light on whether or not this is possible.

• netsh advfirewall firewall

  - by lehn0058

  I am trying to write a script to configure a windows firewall (server 2008 & 2012 only) to adjust certain firewall settings after a machine has been added to a domain. I need to do this because one of the pre-installed programs on these machines we get only has the firewall rules setup for the public and private firewall profile. This script will be pushed out for other admins to use, and some of the machine will be in other languages. The command to change an existing firewall rule is as follows: netsh advfirewall firewall set rule name = "rule name goes here" new profile=domain This command works great. However, I need to do this for about 10 firewall ports AND since the program could be installed on computers with different languages, I can not just pass the name of all of the firewall rules. Is their some way to do this by supplying the port number? Or some way to specify a regular expression so I could use any rule that has a name LIKE 'test'?

• How to setup wireless radio to network using 2 nics?

  - by CptanPanic

  I am having problems setting up this network, hopefully someone can help me. Laptop <- Wireless Radio <- ... - Wireless Radio <- CPU1( NIC1,NIC2) <- SWITCH <- CPU2 I have a computer with 2 NICs (CPU1). One goes to a wireless radio that connects to a wireless laptop, the other NIC goes to network switch. I can't connect Wireless Radio to switch due to space constraints. All the machines and radios are on same network addresses. I tried using Window's Bridge network which did allow Laptop to reach CPU2, but not CPU1. What is the way to get this to work so all the computers can talk to each other?

• Network Role based routing

  - by Steve Butler

  Apologies my networking skills are a tad rusty. I'm looking for a way to setup a system that gives me the ability to setup Role-based access to specific network resources. For example, i have three private subnets for specific groups, users will need access to one one or more subnets. I'd like to have all client machines on the same subnet/vlan, and then use 802.1x to authorize into a router(NAC device/whatever), the router would then see what user had authenticated(huge plus if it could determine AD group), and then allow routing to one or more of the three private subnets based upon their group membership. I've looked at packetFence, and it appears to work by assigning a client to a VLAN, but i'd still need a way to route some users into different back-end networks.

• Catch headset pause/play keypresses in Windows

  - by akshay2000

  I have a new Ultrabook which has single audio jack for input and output instead for separate 3.5 mm jacks we used to have on older machines. The jack is probably similar to American Audio Jack specification or like the one found on Macbook Pro. I have tried to use it with the Apple, HTC, Nokia earphones which ship with most of the smartphones. Microphone on the headset works the way it should. Thing is that the headsets also come with remote controls to control volume and playback. I am sure that those key presses are sent to the Windows. I was hoping to catch those events and bind those to actual media keys so that I can control music playback. I guess this happens on Macs. I want to do the similar thing on the Windows. I'm just not sure where I can catch the events. Driver level? Application level?

• Is there a way to force/manage file locking in windows?

  - by JPbuntu

  I have a 2 Windows machines networked and I am having trouble with simultaneous access to files. I would like only one user to be able to open a file at a time, which I thought was automatic, using file locks.... if the program used to access the file is locking the file. I believe the problem I am having is some of the programs I use, don't lock the file, and there for can be modified simultaneously by multiple users, which is very much not desired. Currently I am having this problem with only two computers, although as soon as I can figure out a solution to this problem the network is going to be expanded to 6 computers, which will include Windows 7, Vista, and XP, as well as a central file server (Samba). Is there a way to ensure that all files opened in windows get locked? Any suggestions are appreciated, thanks.

• Sun OS 5.10 not honoring .hushlogin

  - by nixomose

  I scp and ssh a zillion times a day, and because of our corporate policy I can't get rid of /etc/issue or /etc/motd on the destination machines. So whereas I just want to see the results of my scp or ssh, all I ever end up seeing is thousands of copies of the motd. .hushlogin doesn't seem to be honored. Any other ideas on how to get rid of the message display? Is there some sshd config setting I don't know about (though I probably couldn't change that either)? Is there some curiously sunos/solaris specific way to achieve the goal?

• Why Java applicaiton is running slow for clients on Linux

  - by Darshani

  We have two linux servers which have Apache Tomcat Installed. One is running the Database, the other is running with Java application. More than 100 users are connected to the servers. Server machines are quad core normal PC's which have 4 GB memory. It was running properly for the last 6 months but the application has recently started to run slowly . Suddenly the Java application is getting stuck & users cannot work for some time. There is no network issue. I am trying to identify the reason for this, whether it is a machine problem or the problem is in the Java application. Can any body help me with this?

• Setting up virtual network in VMware workstation

  - by Saif Bechan

  I am playing around with VMware workstation and am trying to set up a small virtual network. I am having a little trouble with this I hope somebody can help me out. I want to have all the different virtual machines to have different internal IP adresses so I can ping them SSH etc, from within my windows machine. I am directly connected to the internet without a router, so using a bridged connection does not seem to work. The other options NAT and host-only do not seem to work also. I think i need to create a new adapter. I am testing this out with a virtual image of linux debain 5.0 lenny. I have WMware Workstation 7 with virtual network editor. Can anyone guide me in the right direction.

• How do I know when my on-board ethernet is dead? (Realtek 8112L LAN controller w/ AI NET2 )

  - by Usagi

  So I have an ASUS P7P55D-E Pro motherboard. It has an on-board Realtek 8112L LAN controller w/ AI NET2. I suspect that my LAN controller is dead but I don't really know for sure. This is what I know thus far: Everything was working, I have a triple booted system and ethernet was functional under Linux, Win7, and OSX. My ethernet is no longer functional under all three of the operating systems. I was experiencing random momentary internet outages before everything finally went dark. I don't know much about the AI NET BIOS tool but I believe it just checks for ethernet problems before you boot into an operating system. In any case, it doesn't find a connection upon boot. I've checked the connection on a couple of other machines and everything worked fine. I think I already know the answer to my question, but are there any other possible explanations, or is it dead?

• Esxi with iSCSI SAN slows down with many multiple VMs running

  - by varesa

  I have a server with ESXi 5 and iSCSI attached network storage(4x1Tb Raid-Z on freenas). Those two machines are connected to each other with Gigabit ethernet, and a procurve switch in between. After a while, if I have many(4-5 or more) vms running, they start to get un-responsive (long delays before anything happens). We are trying to find the reason behind this. Today we looked at esxtop, and found that DAVG of that iSCSI LUN stays at 70-80. I read that +30 is critical! What could be causing those high response-times?

• Log into AD account through Command Line

  - by CranialPain

  Our SBS2003 server likes to lose connection every so often. This appears to 'kick' everyone out, so that no-one can access the server or its shared folders without a log off log in. It usually brings up an error message stating that Windows 7 (on the client machines) cannot find the server, even though its ping-able. Is there a way to login through the command line so I can just write a batch file and have the users double-click it and enter their credentials instead of closing down programs and logging out/in over and over?

• Is there a way to share a scanner with an Airport Extreme?

  - by Electrons_Ahoy

  I've got an Airport Extreme as my home network's router. (Sidebar: I love it.) The printer sharing is pretty phenomenal - I've got my printer hooked up to the base station and all the machines in the house can print to it just fine. However, I have one of those combined scanner/printers, and nothing on the lan seems to be able to see the scanner. Is there a way to get the Airport Extreme / Bonjour to also share the scanner half of the device? For the record, this is an all Windows LAN, so I'm using Bonjour for Windows to get the print sharing to work. Also, I'm hoping to not add a whole stack of extra software to the ecosystem - only one machine in the house needs the scanner, so I can just plug the printer back into that machine and share the printer that way. Still, the Airport and Bonjour seem fancy enough that this seems like it should be doable.

• Windows 7, connecting to Samba shares

  - by Colin Pickard

  How can I connect to a Samba share with authentication using Windows 7? We have a bunch of Linux, HP-UX and AIX servers on our network with folders shared using Samba. These are not connected to our Active Directory or anything, we just type a user name and password when we connect to them. They still all work fine from Windows XP, but we've upgraded a couple of machines to Windows 7 and they can't access the shares. You get prompted for a password but it says "The specified network password is incorrect" (it's not).

• Access Linux Samba-Share from Snow Leopard

  - by Space_C0wb0y

  Hello there! I have a linux machine with a samba-share. Other windows machines can access that samba-share no problem. Now I have a new MacBook running Snow Leopard and I have no clue on how to access it. In finder it shows the linux-machine, but I have no idea how to access it. In some blog it said that this: `smbclient -U <username> -L <hostname>` can be used to list samba-shares. When I do it, I get `session setup failed: NT_STATUS_LOGON_FAILURE` I am at a loss here. Any help on how to approach that problem would be appreciated. Can you provide some hints or point me to some good howto?

• Creating New WebSphere cluster

  - by user154561

  I need to improve WAS perfomance and want to make cluster. I have two separate machines with WebSpphere 7 on it. As I see to do this, I need to add node from my second (remote) WAS to the first one. I try to use "Add node" from console, but without success. It can't find host when I try to execute it. WAS help says about host: Specifies the host name or IP address of the node to add to the cell. A WebSphere Application Server instance must be running on this machine. Does that mean that I cannot add node from a remote machine with "add node?"

• Super simple high performance http server

  - by masylum

  I´m building a url shortener web application and I would like to know the best architecture to do it in order to provide a fast and reliable service. I would like to have two separate servicies in different machines. The first machine will have the application itself with a apache, nginx, whatever.. The second one will contain the database. The third one will be the one that will be responsible to handle the short url petitions. For the third machine I just need to accept one kind of http petition (GET www.domain.com/shorturl), but it have to do it really fast and it should be stable enough. Which server do you recommend me? Thank's in advance and sorry for my english
