  • Multiple Session using port 1081 in one box using SSH

    - by regmaster
    Hi Guru's, I am setting Linux Hopping Station to another different servers. My current config to connect to another servers is using different port to connect. e.g ssh -D 1080 -p 22 [email protected] ssh -D 1081 -p 22 [email protected] Now what I would like to have to share the same port from the same box. ssh -D 1080 -p 22 [email protected] ssh -D 1080 -p 22 [email protected] But when I share it, I will get below error: bind: Address already in use channel_setup_fwd_listener: cannot listen to port: 1080 Could not request local forwarding. How could I configure the same port? help. thank you. I want to share the same port because this is needed when configuring firewall in Citrix Firewall on other machine, not needed to many many ports and keep changing when changing connection. thank you.

  • Samba Permissions

    - by Nelson
    I have Samba set up on a Fedora 15 Machine. All looks well except that there's something nagging and I don't know what exactly is causing it. I have a public share on the server which is accessible by everyone and its permissions is set to 777. When one person opens a document under that share and closes it after working, the other person who opens it can't edit or save it because it opens in read only and shows that it's still open on another computer. What might be causing this and how can I resolve this?

  • Grub2 menu after vmware gust customization

    - by poopa
    Hi, I have ubuntu 9.10 desktop VMware VM with the default grub2 installed. There is some weird problem with this VM. When you clone this vm and have a customization script run, the cloned machine crashes at first boot (VMware does not officially suport customizaing Ubuntu newer than 8.04). After the creash the Grub boot menu is displayed but there is not time out. I checked /boot/grub/grub.cfg and it does indeed show a timeout of 10 seconds. Nothing happens till I select an option with the keyboard. The second time the Ubuntu loads, it does not crash. My question is, how do I make the grub menu timeout in that case? Thanks.

  • Virtualise Excel in a browser

    - by Macros
    Is it possible to give users access to a virtualised instance of Excel - I don't want to give them access to a full OS (although this will clearly be running in the background, all they can access is Excel - they don't even see any other screens)? Secondly, if it is possible, is it possible to do within a browser? Edit I am building a system which is designed to test candidates skills in Excel and for this reason needs to use the full desktop version and not a web app. I don't want to have to ensure Excel is installed on the client machine as there will be issues around differing versions and security as the workbook(s) that are used in the test use VBA extensively to customise and mark the exercises. Ideally my web app would be able to open a session to the server which then just puts the user into an instance of Excel without ever seeing a desktop. I would also need to be able to pass in command line parameters in order to define which workbook to open and also pass in a unique token to identify the user

  • MS 2008 R2 Drops Remote Desktop Sessions in 10 seconds or less every time

    - by mike42
    I'm adding a new 64-bit server to our domain. Everything seems fine except when accessing the machine using remote desktop, after a few seconds the connection is lost. The error message is "This computer can't connect to the remote computer." "Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator." A similar result with Telnet on port 3389. I am able to connect but if I hit a key the connection to host lost. The event log shows the successful login. No errors. Any ideas?

  • EC2 Image to start

    - by HD.
    I'm starting to test EC2 for a couple of new projects. I need to choose an AMI (Amazon Machine Image) and Amazon offered me as first option Fedora Core 8, which is a very old version of one of my favorites distributions. There is a lot of choices, but it's not clear for me which one is the better option. I have my own reasons in order to choice a distro and a version when I need to install a new server but I don't know If I can apply the same for EC2. I know there is a beta for RHEL, how stable is this beta?, How can I choose between all the CentOS AMIs in the list? So this is my question: Do you recommend an AMI to start with EC2? Thanks

  • Running a service as root

    - by kovica
    I have a java program that I use to automate the process of creating VPN settings for clients. The program calls couple of bash scripts, create and copies files around. I have to run it under root user because the whole VPN config is under /etc/openvpn. For this directory I need root privileges. On the same machine I have Glassfish application server and it will call the mentioned Java program. Glassfish is run under non-root user. What is the best, most secure way of running a program as a root user of course without entering a password if I run it via sudo?

  • Mount a remote Linux hard drive as another Windows 7 partition during boot?

    - by zhuanyi
    I would like to mount a hard drive on a remote computer (running on CentOS 6) as a Windows drive so that I can install programs to that drive. The primary hard drive for my Windows machine (which is at home) is pretty small, I have a Linux server sitting in a remote data center with a much larger hard drive and allow me to install more stuff. I know most of you are going to say Samba, unfortunately the biggest problem for me in this case is that I can not mount Samba as a network share unless I start OpenVPN or SSH tunneling first, which is not good for my case because I will install some startup programs to the remote drive as well. Therefore, the remote drive has to be ready and work just like another drive BEFORE any of the startup programs start to load. Is that possible? My home PC has Windows 7 Professional 32 bit installed and the remote server is a Xen virtual server running on CentOS 6. I have admin/root permissions for both. Thanks a lot!

  • How can I fix a computer that is infested with malware and is extremely unresponsive? [closed]

    - by fredley
    Possible Duplicate: How do I get rid of malicious spyware, malware, viruses or rootkits from my PC? I'm troubleshooting a Windows 7 PC for a friend. A couple of days ago it started running 'slow'. It turns out 'slow' is about 15 minutes to the first glimpse of the desktop, and another 30 to show icons. It is possible to open Task Manager, and nothing seems awry, CPU usage at 1-5%, plenty of memory free. The machine is clearly infested with malware though, in particular a program called 'Optimizer Pro' is demanding money to 'remove 5102 files slowing down my computer'. This seems highly suspicious. My problem is though, that I can't access msconfig (I left it for a couple of hours after having hopefully typed it into the Start Menu and hit enter - nothing seems to have loaded), or anything at all basically. I can boot from a Linux Live CD, but can I actually do anything useful from there? System Restore hasn't fixed it either, and Safe Mode exhibits the same behavior.

  • How to dual boot Ubuntu 12.10 and Windows XP sp3 on Dell Dimension 8250 desktop using 2 hard drives

    - by user106055
    I'd like instructions to dual boot Ubuntu 12.10 and Windows XP (sp3) on my desktop Dell Dimension 8250 (this is old and has 1.5 GB RAM which is maximum). I will be using 2 hard drives. Windows XP is already on a 120 GB drive and and Ubuntu 12.10 will go on a separate 80 GB hard drive. Both drives are IDE using a 80 conductor cable where the 40 pin blue connector connects to the motherboard. The middle connector is gray and is "normally" used for slave (device 1) and the black connector at the very end of the cable is meant for the master drive (device 0) or a single drive if only one is used. First, I do not wish the XP drive to have its boot modified by Ubuntu in any way. It should remain untouched...virgin. Let me know where the XP drive and the Ubuntu drive should be connected based upon the cable I've mentioned above, as well as jumper settings for both during the whole process. I'm just guessing, but should I remove the XP drive and put the empty Ubuntu drive in its place and install Ubuntu? By the way, I already have made the DVD ISO disk. For your information, the BIOS for this machine is version A03. When I tap F12 to get to the boot menu, I have the following choices: Normal (this will take me to a black screen with white type giving me the choice to boot to XP or to my external USB backup recovery drive) Diskette Drive Hard-Disk Drive c: IDE CD-ROM Drive (Note that if the CD Drive is empty, it will then go to the DVD drive) System Setup IDE Drive Diagnostics Boot to Utility Partition (This is Dell's various testing utilities) Thank you in advance for your help.

  • Does Windows 8 include the Windows Help program (WinHlp32.exe)?

    - by amiregelz
    In 2011, Symantec reported on the use of the Windows Help File (.hlp) extension as an attack vector in targeted attacks. The functionality of the help file permits a call to the Windows API which, in turn, permits shell code execution and the installation of malicious payload files. This functionality is not an exploit, but there by design. Here's the malicious WinHelp files (Bloodhound.HLP.1 & Bloodhound.HLP.2) detection heat map: I would like to know if the Windows Help program exists on my Windows 8 machine by default, because if it does I might need to remove it for security reasons. Does Windows 8 include the Windows Help program (WinHlp32.exe)?

  • use correct-resolution background desktop image

    - by Rob Bos
    I have a desktop background image (a picture) in a half-dozen different resolutions, that I'd like to deploy to a disparate collection of computers with different monitors and video cards and whatnot. Laptops, netbooks, desktops, widescreen, and even a couple of "tall" screens. I have images to cover most of the cases. I would like Windows 7 to correctly pick the correct desktop background image via group policy. Now, the logon screen is already done. The OEMBackground method is rather clever, and lets you copy files of different resolutions to the machine, and the logon app will calculate the aspect ratio of the monitor and match it to a file as closely as possible. Is there any way to have that functionality on the desktop background as well?

  • What is the easiest way to make a backup of an entire hard disk

    - by Solignis
    Hi there, I got myself a dell laptop from the local computer store. Its a used machine with Windows Vista Home Basic on it. I want to load Ubuntu Desktop 10.10 though so I can do perl development. BUT I want to keep a copy of the entire harddrive with the dell utility partition and Windows Vista in case I want to go back. I was thinking I could image the drive but I not sure what to use, I don't have Ghost or anything, Someone had told me about Clonezilla. Would that work for me? Is it hard to use? Also I want to burn the data to a DVD or something more storable than a harddisk.

  • Mac OS X Server 10.6.6 "disables" CPU in VMware Fusion [closed]

    - by wjlafrance
    Hello! I installed Mac OS X Server 10.6.0 in VMWare Fusion the other night and it worked perfectly, until I ran Software Update. I upgraded to 10.6.6 through the combo updater, and now when I start the VM it says: "The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point." I've switched the operating system in the options to OS X Server 32bit, 64bit, and even to Windows 7, and nothing has worked. Does anyone have any ideas?

  • VGA passthrough and desktop virtualization

    - by Zacariaz
    In short, my dream is to have one machine with multiple paravirtualized desktop and server guests, one of which has to be a Windows desktop with powerful graphics. As Windows can't be paravirtualized in the normal sense of the word, I was quite happy when I heard about VGA passthrough, but then I read on. As I understand it, such a setup would mean that the Graphics will be dedicated to one particular guest, thus you wouldn't be able to switch between guests. If this is in fact so, would someone please explain to me what the purpose/use of VGA passthrough is? I can think of no real use for it. Yes it's a cool technology, but to me it seems pointless. It's true that it's possible to passthrough individual VMs to separate GPUs, which is also cool, but in the end I should think that two seperate computers would make life a whole lot simpler. Again it seems rather pointless.

  • Opensolaris, ZFS shares

    - by Random
    I've recently updated to OpenSolaris 2010.05 from 2009.06. Its currently set up to share one of the the ZFS zpools to the other machines on my network. However, only a single account is able to access these shares. My other accounts get refused when attempting to connect. File permissions are all correct - When logging into the machine directly with the other logins, I can see, and play with the files and directories as normal - Its just the share that gets refused. The interesting thing is, I could access the shares prior to upgrading. Nothing else was changed other than the straight upgrade. I am pretty sure there is no user specific sharing going on. What could be preventing others from accessing this zpool?

  • Unable to install visual studio 2012 on windows 7

    - by Nirvan
    I was attempting to install Visual Studio 2012 Express Version on windows 7, but got the following error. The error talks about some Interop Assem, which I believe is related to Microsoft Office. I tried to install the Interop Assem, but it seems that they cannot be installed for Starter Versions of the Microsoft Office. So, how do I go about installing Visual Studio 2012 on my Windows 7 machine, without full version of Microsoft Office installed, Or the error is related to something else. Update: I have tried to install the following Interop Assem but the installation terminates without any status.

  • Flash Player is creating thousands of .tmp files

    - by Ed Manet
    We have seen a number of machines in our environment (XP Pro SP3) that have been running out of disk space because of .TMP files in the windows\temp folder. One machine had 6GB of .TMP files on it starting from around August 2010. The files are all 305kb in size and they seem to get created every 10 minutes. The files appear to be either .EXEs or .DLLs when opened in a hex editor. The words "this program can not be run in DOS mode" are at the beginning of the file and the words "Adobe Flash Player" are scattered all over the end of the file (probably the string table). While it's easy enough to clean them up, I'd like to find root cause for the issue. Has anybody else seen this?

  • Safest snapshot of a failing harddrive?

    - by ironfroggy
    I have a headless machine that stopped booting, so I pulled it out for diagnostics and got a message that one of the harddrives was about to fail, so I pulled them all out and I need to get everything off, before figuring out which I need to get rid of. I wasn't sure which drive was failing, because it only said "Harddrive 1" and I don't know which it referred to. I'm wondering the best way to get everything off. I'm worried if I copy everything, I could get corrupt data and not realize some files are wrong until the drive is completely out of commission. What are my best options to get everything off in a way I can safely move to new storage?

  • Free firewall for Windows Server 2003

    - by n00b_Admin
    We have a Windows Server 2003 R2 Machine here at work that I need to ensure is accessible only from specific set of IP Addresses. The Server is on a LAN and I am aware that one of the possible solutions maybe limit access to the Server's VLAN. However that is not feasible at the moment. I've been searching for a firewall that could do this, Windows' Firewall is pretty limited and I don't see an option in it to limit incoming data based on Source IP addresses. Most free firewalls like Comodo and ZoneAlarm don't work on Windows Server. Any ideas on how to accomplish this would be of great help. Thanks in advance.

  • Wifi and eth behavior

    - by r00ster
    I have a wireless router 150M Wireless Lite N Router Model No. TL-WR740N / TL-WR740ND. Normally, when I'm connected to the local network using eth0 I can ping other machines by issuing ping name. When I'm connected through wifi I have to issue ping name.domain.com. The machine is only visible in intranet. How to achieve the same behavior with wifi? The second problem is, that I can not connect to some external sites through wifi but through eth everything is ok. I guess that is related to some port forwarding, but I'm not sure. How can I resolve this issue? EDIT: I'm using Linux Mint.

  • Error sysprepping Windows 8 Enterprise 90-day trial

    - by Philip
    I am using the Windows 8 Enterprise 90-day trial to evaluate the latest version of Windows for a private school. The way I work is that I use sysprep to prepare an generalized image, then I clone it to the school's computers. When I follow the instructions and try sysprep on my installation of Windows 8 in VirtualBox, sysprep thinks briefly and gives me an error message: Fatal error occurred while trying to sysprep the machine. Once I acknowledge it, sysprep closes. I checked the Windows Event Log, and there's nothing there that I could see. I also followed some instructions to cure this problem, but nothing changed. The error remains. My best guess is that the 90-day trial prohibits the use of sysprep, but I can't be sure. It might also be my use of VirtualBox, or who-knows-what. Has anyone had success with this, or encountered the same issue on real hardware?

  • Squid 2.7.6 not honoring ACL rules

    - by peppery
    Hello there, I have a /24 block of IP addresses assigned to a single server that I have been attempting to install Squid on an Ubuntu server machine. All of the IP addresses are set up correctly (aliases of eth0) in /etc/networking and work as they should be, using cURL I can specify an interface and it goes out on the correct address as it should be. I would like Squid to take the incoming IP address the request was sourced to and proxy the request out on the same IP (e.g incoming 123.123.123.1:3128 - 123.123.123.1, .2 - .2, etc) and have set up these ACL rules in /etc/squid.conf acl ip1 myip x.x.x.1 tcp_outgoing_address x.x.x.1 ip1 acl ip2 myip x.x.x.2 tcp_outgoing_address x.x.x.2 ip2 acl ip3 myip x.x.x.3 tcp_outgoing_address x.x.x.3 ip3 and so on, as this seems to be the only way to do what I want (from research). However, after much frustration, Squid seems to be ignoring these rules and sending requests out on the default interface. Does anybody have any suggestions? Thanks.

  • Reducing the size of the EDB file.

    - by Toby
    I have hit an issue on a MS SBS machine where every morning the datastore for the exchange mailboxes dismounts itself. We believe the issue is that it has grown too large over time and needs cut down a bit. As part of this we have removed (purged) some mail files that were no longer needed, which should have given us a saving of roughly 3GB (more than enough saving for what we need). So I deleted the mailboxes, then purged them and noticed that the .edb file was still reporting the same size, I dismounted and remounted it to see if that would have any effect but it did not. Am I missing a step? I have read online that you can run offline defrag on the file but that seems to only save you a small amount of whitespace. Any help would be greatly appreciated.
