• how to remotely setup powershell to accept Enter-PSSession

  - by user1399195

  I have some computers I'm trying to remotely execute powershell commands but I'm running into some snags. For one thing, the computers do not have Enable-PSRemoting enabled so I am unable to simply Enter-PSSession. I tried to run a powershell script through psexec but I have yet to Set-Execution Policy on the machine. My thoughts were to execute a powershell logon script that accomplished this but before I tried this I was going to see if there were any other methods to enable-psremoting on a machine. Thanks in advance!

• Help, my CentOS servers keep going down , No route to host after a random uptime

  - by user249071

  Hello , I have a couple of Centos linux servers, that have a very simple task, they run nginx + fastcgi for php , and some NFS mounts between them, readonly They have some RPC commands to start some downloading processes with wget, nothing fancy , from a main server, but their behavior is very unstable, they simply go down, we tried to monitor ram , processor usage, even network connections, they don't load up so much, max network connections up to... 250 max, 15% processor usage and memory , well, doesn't even fill up, 2.5GB from 8GB max , I have no ideea why can a linux server go down like that, they aren't even public servers, no domain names installed no public serving, for sites. The only thing that I've discovered was that if i didn't restart the network service every couple of hours or so... the servers were becoming very slow, starting apps very slow, but not repoting a high usage of resources...Maybe Centos doesn't free the timeout connections, or something like that...It's based on Red Hat right? I'm not a linux expert , but I'm sure that there are a few guys out there that can easily have an answer to this , or even have some leads to what i can do ... I haven't installed snort, or other things to view if we have some DOS attacks, still the scheduled script that restarts the network each hour should put the system back online, and it doesn't.... Thank you in advance

• Cannot acess the new cloned server even after new IP address assignment

  - by tough

  I was able to clone a Ubuntu 10.04 server residing in Cloud. It appeared that I was not getting some IP for the new VM so I followed some of these: # cd /etc/udev/rules.d # cp 70-persistent-net.rules /root/ # rm 70-persistent-net.rules # reboot I didn't follow the later commands as I was unable to see two eth MACs as available in the referenced site. After this I am able to see some the IP for it, and is different form the original IP, I have added new IP to DNS server. Now when I try to access it with its assigned(new) domain it is directed to the old server. I can see both the VMs running with different IP. Where I might have gone wrong, I am new to this admin thing.

• VBA - Instead of ActiveExplorer.Selection to set folder, explicitly set folder path

  - by Mike

  Sub MoveItems() Dim Messages As Selection Dim Msg As MailItem Dim NS As NameSpace Set NS = Application.GetNamespace("MAPI") Set Messages = ActiveExplorer.Selection If Messages.Count = 0 Then Exit Sub End If For Each Msg In Messages Msg.Move NS.Folders("Personal Folders").Folders("SavedMail") Next End Sub This code will move all email messages from the currently selected folder in outlook to another folder (SavedMail). I would like to edit the code so that instead of using the currently selected folder as the source for the messages, there would be a hard-coded folder - something like Set Messages = NS.Folders("Personal Folders").Folders("Moved"). I'm a VBA rookie and tried just replacing the Set Messages line with this which resulted in a Run-time error '13': Type mismatch which I think refers to a mismatch of the Dim Messages and the Set Messages commands. I've tried using different Dim definitions with no luck. I'm guessing that someone who knows VBA will see the way to do this right away. Any help would be greatly appreciated. Thanks.

• Enable 8th bit as Meta in zsh without a warning

  - by Bostonvaulter

  In my quest to configure my shell to work exactly how I want it with respect to the alt/meta key I am having some trouble. Recently I added "bindkey -m" to my .zshrc and now whenever I start a zsh shell (ie open a terminal window) I get this error "warning: `bindkey -m' disables multibyte support". Now since I don't care much about multibyte support atm, is there a way I can disable just this warning? Even better would be a way to use 8th-bit meta as well as multibyte. Also note that this happens on a clean zsh install on 4.3.9 and 4.3.10 My reasoning for wanting bindkey -m vim: alt mappings (my own personal commands/mappings) zsh: alt mappings (such as Alt-. to recall the last argument of the previous command) emacs: alt mappings (lots of built-ins) So, is there any way to disable this warning or otherwise accomplish what I'm trying to do?

• Remote desktop to my KVM virtual machine

  - by user6

  I've got a dedicated server running Debian 6. I've set up a windows 7 virtual machine using KVM. Now I'm trying to get Remote desktop working. I'm guessing i have to do some port forwarding. The virtual machine is in a NAT. Remote desktop is already set up on it (another virtual machine can connect). I've tried using the iptables and countless of virsh commands of which I'm not even sure what they did. Anyone knows how to get this working?

• IDE Motherboard to Boot from a SATA 1T Hdd

  - by JavaMan

  I want to use my SATA HDD in my very old ASUS A7V8X-X motherboard (made in 2003). I intended to buy a cheap adapter for this. Say something similar to this one: http://www.cooldrives.com/satoidecofor.html But would there be any issue if I want to boot from this SATA drive? My impression is that these kind of adapters convert SATA signal and commands to PATA directly and such a low level conversion should be transparent to the motherboard and BIOS - in case the BIOS doesn't support SATA. And, for my motherboard, it sure doesn't. Does anyone ever used such a kind of adapter to support a boot drive? Any success sorry?

• Is there any proper documentation for mod-evasive?

  - by Question Overflow

  mod_evasive20 is one of the loaded modules on my httpd server. I read good things about how it can stop a DOS attack and wanted to try it out on my localhost. A search for mod_evasive turns up a blog post by the author which briefly describes what it does. Other than that, I can't seem to find a reference or a documentation on the apache modules site. I was wondering whether it is a module recognised by Apache since there is no mention of it on its website. I have a mod_evasive.conf file sitting in the /etc/http/conf.d folder that contains the following lines: LoadModule evasive20_module modules/mod_evasive20.so <IfModule mod_evasive20.c> DOSHashTableSize 3097 DOSPageCount 2 DOSSiteCount 50 DOSPageInterval 1 DOSSiteInterval 1 DOSBlockingPeriod 10 </IfModule> My understanding from the setting is that if I were to click refresh or send a form more than two times in a one second interval, apache will issue a 403 error and bar me from the site for 10 seconds. But that is not happening on my localhost. And I would like to know the reason. Thanks.

• Moving FederatedEmail/SystemMailbox from One Store to Another - Exchange 2010

  - by ThaKidd

  Hello all. Just upgraded from Exchange 2003 to 2010. Somehow, I have two mailbox databases on my single Exchange 2010 server. One database contains all of the mailboxes I had moved from the 2003 exchange server; the other contains two SystemMailboxes and one FederatedEmail box. I am just starting to get a grasp on the commands used in the EMS. I was wondering if someone could point me in the right direction to move these three "system" mailboxes into my actual mailbox database so I can eliminate the second database. Just trying to sure up this one server before I role out my backup Exchange server. Thanks in advance! Your help and ideas are greatly appreciated as I try to make this setup as simple as possible.

• View Public Key in Domain Key for a Domain

  - by Josh

  Using Jeff's blog post I'm creating domain keys for my account. I wanted to verify the setup using Get or Host command with Bind for Windows but I'm lost one of the commands. I can see view the _domainkey. txt file with this command: host -t txt _domainkey.stackoverflow.com but I'm at a loss at how I'd find the selector record. Jeff points out it can be anything before the before the period in "._domainkey.domain.com" but how would I list all records if I didn't know the exact query name? Is there a wildcard I could use to view all TXT or all records under this section?

• Connect through SSH and type in password automatically, without using a public key

  - by binary255

  A server allows SSH connections, but not using public key authentication. It's not within my power to change this at the moment (due to technical difficulties, not organizational) but I will get on it as soon as possible! What I need now is to execute commands on the server using plain old account+password authentication from a script. That is, I need to do it in a non-interactive way. Is it possible? And how do I do it? The client which will be executing the script runs Ubuntu Server 8.04. The server runs Cygwin and OpenSSH.

• Am I using too much memory? (Rails on EC2 with Resque)

  I am looking at the memory usage of the Rails application (it uses background processes via Resque) and since the common answer to the question, "how many workers is too many" was "test and see", I ran some memory commands and wonder if someone can help figuring if the memory usage is high enough already, or I can still add some extra workers.. so (this is all under the maximum load): $ free -t -m total used free shared buffers cached Mem: 1756 1532 223 0 12 229 -/+ buffers/cache: 1291 464 Swap: 895 10 885 Total: 2652 1543 1108 $ vmstat procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 10588 156172 13400 326476 1 6 4 0 5 4 1 0 99 0 If there is any extra info I can provide to help answer this, I would be happy to do so.

• Is it possible to install and use a printer in Azure Worker Roles?

  - by lurkerbelow

  I'd like to know if it's possible to create and use a printer in Azure Worker Roles. I do know that I can install printers with basic batch commands. So I could define a batch script that would run as a startup task. something like: rundll32 printui.dll,PrintUIEntry /if /b "printer" /f %windir%\inf\ntprint.inf /r "file:" /m "printername") Question: Can I use a printer to print to file, maybe to local storage? I do need the function to print to file or atleast to have a printer installed, because I have to get the PCL output from different installed printers. Sadly I can not test it by myself. I do not have a CC to join the 90 days trial.

• Is it possible to use different keyboards for different applications?

  - by Paperflyer

  What I would like is this: I would have two keyboards. One of them is "connected" to Matlab, the other is "connected" to my text editor of choice. This way, I could edit some script and still test some commands in Matlab without having to constantly switch between the applications. Basically, I would want to have an additional keyboard attached to my computer that solely controlled Matlab. That would be awesome! Is there any way to do this? Preferably with OSX, but it would be fun on Windows or Linux, too.

• Debian/Ubuntu apt or pbuilder without root privileges?

  - by Tem Pora

  I want to use apt or pbuilder to build a package in user's home directory. The home directory has enough space to hold the package's source, its dependencies and binary output. But the apt and pbuilder documents say that you have to be a root user (sudo) to use it. It's frustrating, as the only way now I have at my disposal is to build the package from source or use the dumba$$ (sorry for bad language) dpkg and in both cases figure out every dependency manually, create the dir layout manually and install the built things manually. Now if I can do all these things manually, why the tool writers (apt) think that doing so using their tool (apt) is somehow more special/dangerous? I don't want to use root privileges JUST to build and test a user-land package. If I am NOT allowed to do anything outside my home dir then why NOT the apt or pbuilder type commands be allowed to "build" something in my home dir without root privileges? I just want to use their functionality. It seems there is nothing like Gentoo Prefix from Debian

• How to create a filesystem mountable by windows in linux?

  - by wcoenen

  I have attached an external USB disk to my debian gnu/linux system. The disk showed up as device /dev/sdc, and I prepared it like this: created a single partition with fdisk /dev/sdc (and some more commands in the interactive session that follows) formatted the partition with mkfs.msdos /dev/sdc1 If I then attach the USB disk to a Windows XP or Vista system, then no new drive becomes available. The disk and its partition show up fine in the disk managment tool under "computer management", but apparently the file system in the partition is not recognized. How do I create a FAT32 file system which can actually be used in windows? edit: I've given up on this and went with a NTFS file system created by windows. In debian lenny this can be mounted read-write but apparently it requires you to install the "ntfs-3g" package and explicitly pass the -t ntfs-3g option to the mount command.

• Using VLC to Unicast High Definition Webcam over local gigabit LAN with low/zero delay

  - by Robin Day

  We're setting up a webcam "window" between two offices in the same buildilng. The two PC's are connected to the same gigabit switch. We're using VLC to stream the webcam over HTTP using the following commands. vlc dshow:// :dshow-caching="0" :dshow-size="640x480" :sout=#transcode{vcodec=h264,vb=0,scale=0}:http{mux=ffmpeg{mux=flv},dst=:8080/} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep vlc http://192.168.0.1:8080 :http-caching="0" Even with the caching set to zero, the delay in the image is a good 2-3 seconds. The CPU usage of each pc is also maxed. I'm guessing it's the transcoding that's causing much of the delay. Can anyone give me some changes to these command lines that will reduce the transcoding power, or send the webcam over a different protocol, or anything that will reduce the delay of the cameras? Bandwidth is not an issue at all as the pc's can be connected to a dedicated switch/vlan if required.

• Dead-simple USB-based Windows partition cloner?

  - by OverTheRainbow

  Clonezilla is a fine open-source tool, but it requires going through several screens. Since I need to save/restore the same Windows partition, I was wondering if someone knew of a tool (open-source or not) that is easier to use and boots off a USB keydrive. Ideally, it'll save the two commands to save/restore a partition, so I just need to boot the host from the USB key, choose the command, and it'll take care of business. Are there solutions that look like this? Thank you. Edit: Here's one among other articles that shows how to tell CZ to run a script to avoid the multiple screens.

• How do I check to see if an apt lock file is locked?

  - by gondoi

  I am writing a script to do some apt commands, but I am running into potential issues of the apt/dpkg databases being locked so my script bails. I want to check the lock files (i.e. /var/lib/dpkg/lock) before doing anything just like apt does when it runs it's command, but I can't figure out how apt is performing the lock. The lock file is always there, and apt-get is not doing a flock on the file. How else would it be checking to see if it is in use? From an strace I see that apt-get opens the file, but that is it. In my script, I can open the file while apt-get has it open as well.

• Ubuntu doesn't start and I can't login [migrated]

  - by Meph00

  My ubuntu 13.04 doesn't boot anymore. Eternal black screen. If I press ALT+CTRL+F1 I see that it's stucked on "Checking battery state [OK]." I'd like to try to go with sudo apt-get install gdm but I can't login on terminal tty2, tty3 etc. They correctly ask for my nickname, then they make me wait a lot, ask for password and make me wait again. After a lot of time (... a lot) the best I could achieve was visualizing "Documentantion https://help.ubuntu.com". I can never reach the point where I can give commands. Plus, during the long pauses, every 2 minutes it gives a messagge like this: INFO: task XXX blocked for more than 120 seconds. Any suggestion? Sorry for my bad english and thanks everyone for the attention.

• esx 4 - c7000 - cisco 3020

  - by gdavid

  I have 4 blades with esx 4 installed in a HP c7000 enclosure. They have 6 cisco 3020 for hp switches in the backend. The plan was to use 2 switches for iSCSI traffic and the other 4 for data traffic. I am having a problem trunking the switches to our existing environment. The documentation i keep finding online has commands/features that are not available on the 3020 switch. Does anyone have this setup anywhere? I am looking to do Virtual Switch Tagging (VST) so i can control the machines vlan via the port groups. The only time any configuration worked for us was when our network team placed the command switchport native vlan x this setup only allowed vlan x to pass traffic and only when the port group was in vlan 0. Ideas? thanks for any help. -GD
