  • screen resume works on top of VPN

    - by michael
    I connect to my network using VPN. I have screen running and 'ssh' to a server. I then kill my shell and I was able to 'resume' by 'screen -r'. This works as expect. But when I disconnect VPN and re-connect VPN, and type 'screen -r' again. I was not able to get my last screen again. And I see "Write failed: Connection reset by peer46.11 MiB | 642 KiB/s" in the screen. Can you please tell me if it possible to reconnect 'screen' if my VPN is disconnect. Thank you.

  • Is there a way to make software available for remote installation in Windows Server?

    - by Michael J. Gray
    I've heard of folks having a sort of "software repository" which contains a database of product keys and then network installation media for operating systems and other Microsoft software, such as Office. With this, they were then able to join a computer to the domain and grant that user privileges to a set of software and then the client was able to use it either remotely or locally on their machine. I believe it installed from the server on to their local machine. Does anyone happen to know what this is?

  • WinXP How to Tunnel LPT over USB

    - by Michael Pruitt
    I have a windows program that accesses a device connected to a LPT (1-3) 25 pin port. The communication is bidirectional, and I suspected the control lines are also accessed directly. I would like to migrate the device to a machine that does not have a LPT port. I saw the dos2usb software, but that takes the output (from a DOS program) and 'prints' it formatted for a specific printer. I need a raw LPT connection, and a cable that provides access to all the control signals. I do have a USB to 36-pin Centronics that may have the extra signals. I use it with a vinyl cutter that doesn't like most of the USB dongles. It comes up as USB001. Would adding and sharing a generic printer, then mapping LPT1 to the share get me closer? Would that work for a parallel port scanner? My preferred solution is a USB cable with a driver that will map it to LPT1, LPT2, or LPT3.

  • NTFS file size, how do you guys refresh it to view its current correct size

    - by Michael Goldshteyn
    I work in a command prompt quite often and around many large (remote) log files. Unfortunatelly, the sizes of these files do not update as the logs grow, unless it would appear the files are touched. I usually use hacks like the following from Cygwin to "touch" the file so that its file size updates: stat file.txt or head -c0 file.txt Are there any native Windows constructs that can refresh the file size from the command prompt, as unintrusively as possible and preferrably without transferring any (remote) data, since I often need to refresh the sizes of very large files remotely, to see how large they have grown.

  • Why do I get xfs_freeze "Operation not supported" error with ec2-consistent-snapshot? Debian Squeeze w/ext4 filesystem

    - by Michael Endsley
    I'm running the following command: [root@somehost ~]# ec2-consistent-snapshot --aws-credentials-file '/some/dir/file' --mysql --mysql-socket '/var/run/mysqld/mysql.sock' --mysql-username 'backup' --mysql-password 'password' --freeze-filesystem '/dev/xvda1' vol-xxxxxx It returns this error: xfs_freeze: cannot freeze filesystem at /dev/xvda1: Operation not supported ec2-consistent-snapshot: ERROR: xfs_freeze -f /dev/xvda1: failed(256) snap-eeb66393 xfs_freeze: cannot unfreeze filesystem mounted at /dev/xvda1: Invalid argument ec2-consistent-snapshot: ERROR: xfs_freeze -u /dev/xvda1: failed(256) This is being run on Debian Squeeze with the ext4 Linux filesystem. Can anyone explain this error to me, or what might be its cause? When googling, I found information about it needing to be executed with sudo, but I'm performing the entire operation as root. I also found some posts about trying to run it after a CentOS upgrade using yum, but the situation appeared dissimilar. It's difficult to find things referring to this situation exactly. xfs_freeze is available for use on the filesystem. Is it possible that the filesystem, despite being ext4, somehow doesn't support freezing? Sorry if I've missed some bit of StackExchange etiquette with this post -- it's my first venture here!

  • Recommendations for secure business collaboration tools

    - by Michael Prescott
    I'm searching for a secure and easy way for business partners to collaboratively edit and exchange documents, share calendars, create schedules, and assign tasks. I speculate that the ideal collaboration environment or work-flow would actually involve several technologies and services. My co-workers and I have tried a variety of things from Google Apps to Wiki's, but nothing feels very fluid or complete. I suppose defining what we need and our constraints is probably in order: collaboratively edit basic text documents and spreadsheets exchange documents like flow-charts, graphs, and files generated by our other desktop applications, but not source code assign tasks to each other and ourselves and track the history of those tasks easily see when relevant documents have been modified since last viewing and ability to easily push notifications to relevant workers (a clean front page that shows updates would probably suffice) provide limited access to contract workers and guests users if a remote user system is compromised (keystroke logger or other spyware) we don't want the criminal to be able to gain access to all business documents (processes, trade-secrets, customer lists, etc.) simply because they gained access to a single Google account (or whatever web service) Cannot be a difficult to administer VPN infrastructure Cannot cost more than $100 per month (yeah, money is tight) Needs to support up to 25 users We can host our own web applications, but it must be low maintenance solution

  • Is VBoxManage guestcontrol passing parameters incorrectly?

    - by Dan Jones
    I had an idea of using my Windows VM (on a Ubuntu host) to open itms:// links (for iTunes) from the host. So, I'm using vboxmanage guestcontrol to make this happen. I have a script (win_vm_launcher.sh) that takes a link as the argument, and passes it to the host like this: vboxmanage guestcontrol "$VM" exec --image 'C:\Windows\System32\cmd.exe' --username "$USER" --password "$PASSWORD" -- /c start "$@" This works if I copy a link from my browser, and change http to itms. E.g., for https://itunes.apple.com/us/album/new-york-city/id3202598, I can do win_vm_launcher.sh itmss://itunes.apple.com/us/album/new-york-city/id3202598 and it works fine. The album opens up in iTunes on my VM. However, when I click a "View in iTunes" link from the iTunes site, it adds an extra parameter to the URI (specifically, the referrer), so it looks something like itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739 Unfortunately, if I try to run win_vm_launcher.sh itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739 it insteads opens up a regular Command Prompt window with the title "itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739". I don't even know how to set the command prompt window title, so I'm not sure how that's happening. If I run the command in the guest, it works fine, opening the album in iTunes: cmd /c start itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739 I found a VirtualBox bug that seems somewhat related, but not exactly. It probably doesn't matter, but my host is Ubuntu 12.04, and my guest is Windows 7. So, any idea if vboxmanage is incorrectly passing the arguments, and if so, is there a way around it? If I can't figure out the right way to do it, I'll end up having to process each argument, and stripping out any parameters on any URIs. P.S. I tried creating a batch script (out.bat) like this: echo %1 > %TEMP%/testing.txt and then running it from the host like this: vboxmanage guestcontrol "$VM" exec --image 'C:\Windows\System32\cmd.exe' --username "$USER" --password "$PASSWORD" -- /c "C:\path\to\out.bat" "itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739" It ran as expected, and when I open %TEMP%/testing.txt, it contained: "itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739" including the quotes. So, it sort of passed the parameter correctly (not sure why it still had quotes), so maybe the problem is with cmd.exe, or even the start command. I'm stymied.

  • Intel 520 SSD drives not working with lsi controller on VMware esxi 5

    - by Michael
    We have a problem with our LSI 9266 controller. LSI have vmware drivers which normally show the health status of connected drives, raid controller, battery etc from within the vSphere Client. This driver also allows connectivity from the LSI MSM utility from a windows workstation. The problem is as soon as I connect my intel 520 SSD drives the health status in the vsphere client disappears, also we lose connectivity via the LSI MSM utlity. Any other drives we test are fine, 1TB SAS drives, other SSD drives etc are all OK. The Intel drives are on the compatability list and are supported by LSI but dont work with the VMware driver. If I install a windows OS on the physical server we have no problems. I have logged a ticket with LSI but they havent been very helpful. I am trying to find other people that may have had the same issue and maybe even a fix

  • custom route not working on windows

    - by Michael Closson
    My windows laptop is directly connected to 192.168.1.0/24 (wireless lan). I access 10.21.0.0/16 though a router that is connected to both networks. The routing works fine with this configuration. I have a VPN, that connects to 10.0.0.0/8. The VPN network doesn't actually use any IPs in the 10.21.0.0/16 range. So I should be able to configure my routing table to route all the 10.21.0.0/16 IPs through the wireless lan, and all other 10.0.0.0/8 through the VPN. My understanding is that I can do this if the metric for the 10.21.0.0 is lower than that of the 10.0.0.0. The VPN (10.0.0.0) is automatically assigned metric 20. I have manually assigned the WLAN a metric of 1. I manually add an entry to the routing table with this command: route add 10.21.0.0 mask 255.255.0.0 192.168.1.201 metric 1 The route is then assigned a metric of 2 (which is expected). The problem is that it doesn't work. I can't ping any machine on the 10.21.0.0 network. But I can access other stuff on the 10.0.0.0. I can also access stuff on the 192.168.1.0. To debug this i've done the following. Run tcpdump on the router (192.168.1.201). I can verify that no packets for 10.21.0.0 arrive on that interface. Disable iptables on the router. Disable the windows firewall. Run wireshark on my laptop, to try and see which interface the ping requests go to. But I can't see them go anywhere!! The ping command doesn't receive any 'destination unreachable' messages. Here is the relevant section of the routing table. IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.201 192.168.1.18 2 10.0.0.0 255.0.0.0 On-link 10.55.44.203 20 10.21.0.0 255.255.0.0 192.168.1.201 192.168.1.18 2

  • Best way to create a common folder when creating new users that is a drop box, readable and writeable by all users

    - by Michael Prescott
    What is the best way to provide a common drop box for all users, so that any user that is a part of a particular group can read and write to and from the directory? I thought of creating a directory outside of the /home directory, creating a group specifically for accessing the directory, then adding all desired users to that group, and finally adding a symlink to the home directory of each user that points to the drop box folder. That seems like a lot of work. Is there a better way? I'm running ubuntu 10.04 LTS.

  • Supervisord appears to be running, but monitored programs aren't launched

    - by Brad Montgomery
    I've got supervisord 3.0a8 installed from the system package on ubuntu 10.04 (64bit). The supervisor service appears to be running, but it's not launching the configured programs.

  • Issue varnish purge through CloudFlare to Varnish

    - by Michael
    I've been working on this for a while and can't seem to find any solution. I have varnish sitting in front of my nginx server, with CloudFlare sitting in front. When I issue a curl -X PURGE host CloudFlare picks it up and of course denies it with a 503 error. If I use direct.host to bypass CloudFlare it hits the Varnish server and it accepts the request but it does nothing since direct.host isn't used so there is nothing in the cache for that url. I am using WordPress and there is a WordPress Varnish Purge plugin, it says to add the following line to wp-config.php: define('VHP_VARNISH_IP','127.0.0.1') This is specifically to work with proxy servers and/or CloudFlare to make sure the request goes to the Varnish server rather than CloudFlare, but that doesn't seem to help. Anyone see this before and have any idea?

  • Mac - Run java program at launch

    - by emd
    I want to launch a java program (server program) at computer start up. I can run it from the command line perfectly. I created /Library/Server/startFS.sh. The file is executable by root and contains: cd /Library/Server/FiloSync /usr/bin/java -jar /Library/Server/FiloSync/filosync-server-latest.jar -p 7000 -s 7001 I can't get my launchd plist included here, the formatting is all off. I can run it fine from the command line: './startFS.sh' but when I put create the plist (via Lingon), nothing happens. Now, when run, it outputs a few lines to the console. Might that be problem?? I have tried prepending 'nohup' and post pending '&', but no combination seems to work. Help please.

For each user, do i have to both assign one of the global roles for him and also assign a specific project role ? Also, how do i assign a user to a group ? instead of assigning each user a global role i want to assign a group a global role. not so trivial, Can someone please help me ? Thanks.

  • Generating Thermal Printer (Zebra Printer) Sized PDFs for FedEx Labels

    - by Michael Hart
    Background I own a company which does a lot of FedEx Ground shipping. We have a 3rd party fulfillment center, which stores some of our inventory and at our request ships it. Zebra/Thermal printers are the most cost effective shipping label printers available and our 3rd party fulfillment center has one. I want to generate the labels locally then e-mail the 3rd party fulfillment center a PDF of the labels which they can then print out on their printer. Problem The trouble is, I can't seem to figure out how to print these 4" x 6" labels to a PDF, as FedEx (both ship manager and fedex.com) uses javascript to detect what printer I have. Question What's a clever way to send my 3rd party fulfillment center a PDF (or equivalent) of our 4" x 6" zebra thermal printer labels so they can print them out without re-entering the data?

  • With the Supermicro Embeded BMC, is it possible to connect to Serial Over Lan via SSH?

  • How do I disable other monitors while running games in Wine?

    - by Michael Cheng
    My current setup is: * Dual GTS 250 video cards * 3 Monitors * Used nvidia-settings to run each monitor as a separate x session * This is all running on Linux Mint Debian Edition When running games (Starcraft II) in Wine via PlayOnLinux, I've found that the mouse does not get locked. I already tried various solutions littered across the web and none work so I'd rather just disable my other two monitors while playing. Does anyone know of a method where I can turn off my other two monitors (not my primary monitor) while running Wine and then turn then back on afterwards? I don't mind having to manually run a script before and after gaming. Thanks.

  • How to pass bash script arguments to a subshell

    - by Ralf Holly
    I have a wrapper script that does some work and then passes the original parameters on to another tool: #!/bin/bash # ... other_tool -a -b "$@" This works fine, unless the "other tool" is run in a subshell: #!/bin/bash # ... bash -c "other_tool -a -b $@" If I call my wrapper script like this: wrapper.sh -x "blah blup" then, only the first orginal argument (-x) is handed to "other_tool". In reality, I do not create a subshell, but pass the original arguments to a shell on an Android phone, which shouldn't make any difference: #!/bin/bash # ... adb sh -c "other_tool -a -b $@"
