  • Adding cygwin on right click on windows explorer

    - by PushpRaj
    I wish to add a command on right click menu in explorer that opens current directory with cygwin. For same I have successfully added these registries: [HKEY_CURRENT_USER\software\classes\directory\shell\cygwin] @="c:\\cygwin\\bin\\bash.exe --login -i -c \"cd '%1'; bash\"" [HKEY_CURRENT_USER\software\classes\drive\shell\cygwin] @="c:\\cygwin\\bin\\bash.exe --login -i -c \"cd '%1'; bash\"" but this adds the command only when on some folder or drive. I want generic right click on explorer, on which, search gives me this registry to edit: [HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin] @="c:\\cygwin\\bin\\bash.exe --login -i -c \"cd '%1'; bash\"" My problem lies with the value of the key, which doesnt work on %1 but on some static value like /cygdrive/c Could someone please tell me the proper way to pass current directory to the command, also please refer me some basic and advanced pages for same. Thank you.

  • Setting up scripts in Amazon EC2 Cloud

    - by racket99
    Hello, I am currently running a few perl and python scripts on a windows pc and would like to port over to the Amazon EC2 servers running 64-bit LINUX. The scripts are basic web scrapers that go to a variety of websites, get data and then save daily as csv files. I would like to install these in the cloud and get them running in an automated way so that they will run without my intervention. Also given that I don't want to lose all the data if the instance crashes, I should also upload the csv files to Amazon S3. Any idea how I can do this? I am not terribly versed in LINUX nor do I know Perl/Python well. What is the best way for me to tackle thi

  • CHROOT for shell script testing

    - by Josh
    I am looking at setting up a shell script in order to properly document and automate the process I am using to setup a few servers we have. In order to test the shell script through its different stages I was thinking a CHROOT would be ideal, since I can wipe out the "virtual root" and create it on the fly. I have never used CHROOT before, however. I was just curious what are the exact steps I would need to follow to implement this process of creating a chroot (with the basic core functions that would be needed to install apache/php/etc.)? and then destroying it?

  • Cisco NAT + IPSec + Web Server Configuration Question

    - by zagman76
    Hello - I currently have a Cisco 881W, and it is configured with one of our static IPs to do basic NAT for the network. We also have a web server that needs it's own IP. I configured the NAT for the 2nd IP, however now traffic through our IPSec VPN doesn't route to the web server properly (well, it routes to the internet, rather than through the Tunnel). I followed the instructions here: http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080094634.shtml But now the outbound NAT doesn't seem to be working properly - it keeps going to the NAT of the Cisco, and not the designated IP address. If anyone can assist, I would appreciate it greatly. Let me know what you need, and I'll get it to you! Thanks!

  • Extremely slow startup of tomcat

    - by Henrik
    I have a tomcat 7 installation on a Solaris 10 server. My problem is that starting the server (or deploying a new war) is extremely slow. It usually take 30 - 60 minutes. The war application is a medium sized grails application so there are quite a a lot of files. The server is running other server applications as well but from my basic skills I don't see this as a problem. Can anyone give me some tips on how to analyse this? Settings in Tomcat, java, server, disc access or something else? I use these parameters to tomcat: CATALINA_OPTS="-Dcom.sun.management.jmxremote=true -Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=512m -XX:MaxPermSize=512m -XX:+DisableExplicitGC" And I use a 32 bit java 1.6.

  • deploying skype for 50 nationwide users with preset usernames

    - by kevyn
    Is there a way to sign up a large group of skype names at once? is there a way to enable the users to be given a skype username based on their own e-mail addresses? What I would like to do is roll out skype in an office in every county in UK with a pre defined username such as 'mycompanyname-warwickshire', 'mycompanyname-bedfordshire' and so on. Our users are only basic computer users, so I would ideally like this done with as least fuss as possible for them! Thanks in advance ps. if anyone has a good way of doing this by using any alternative software, I'm open to suggestions

  • Terminal Server 2003 Performance Troubleshooting

    - by MikeM
    Let me get your thoughts on terminal server performance problems. The server hosts average 25 users which, after running some numbers, on average use 600MB memory with their main applications running (web browser, adobe reader, IP phone client). All users are on the same LAN as server. We constantly experience slow response and short session lockups. Combined CPU usage is on average 10%. What appears strange to me is that the system shows 29GB physical memory with 25GB of it free. The page file usage is about 50% averaging 9GB used. Some server specs OS: Server 2003 32bit Enterprise with /PAE flag RAM: 32GB CPU: 2xQuad Core @ 2.27Ghz HD: RAID5 1.2GB After doing basic troubleshooting using performance monitor it leads me to believe that the performance problems are caused by the 32bit OS limitation in addressing full 32GB of physical memory even though the /PAE flag is used. Can anyone suggest something, troubleshooting steps that can lead to a more conclusive answer? Thanks

  • Are there any command line utilities which can calculate and/or limit how fast a pipe is running?

    - by stsquad
    I'm doing some basic stress testing of a Linux kernel network IWF with netcat. The set-up is fairly simple. On the target side: nc -l -p 10000 > /dev/null And on my desktop I was running: cat /dev/urandom | nc 192.168.0.20 10000 I'm using urandom for some poor-mans fuzz testing. However I find that even at this rate I can break something quite quickly. EDIT So I've been playing with trickle to rate limit how fast I'm generating data: cat /dev/urandom | trickle -u 10 nc 192.168.0.20 10000 But it's hard to tell if this is working. What would be really useful is a the pv equivilent of trickle that can work with pipes.

  • Are there other application layer firewalls like Microfot TMG (ISA) that do advanced http rules?

    - by Bret Fisher
    Since the old days ISA and now TMG have had several great features that I often want to deploy to my customers because of the enhanced functionality and security, but often the cost of an additinal server HW, Windows Server, and TMG license is too much to justify when compaired to a $300-500 appliance. Are there other gateway firewalls that can perform one or more of these application layer features: pre-auth incoming http traffic against AD/LDAP before sending packets to internal server (forms auth or basic creds popup)? read host headers of incoming http traffic (even on https) to a single public IP and route packets to different internal servers based on that host header?

  • emacs not load (.emacs) configuration file

    - by ant2009
    I am using emacs on ubuntu 9.04. I have my emacs configuration file in ~/.emacs.d directory. My emacs file is called .emacs I have some basic configuration. However, everytime I start emacs it never loads my configuration and I have to keep doing it manually using i.e. M-X Transient-mark-mode My emacs file is listed below: ;; Emac customization file path (add-to-list 'load-path "~/emacs.d") ;; Use font lock mode (global-font-lock-mode t) ;; Highlight cursor line (global-hl-line-mode t) ;; Highlight selected region (transient-mark-mode t) I want to add to this configuration instead of manually added entries. Many thanks for any advice,

  • Getting rid of GNU Emacs's menu bar in terminal windows

    - by Ernest A
    How to get rid of Emacs's menu bar in terminal windows? The standard answer is to put (when (not (display-graphic-p)) (menu-bar-mode -1)) in init.el. However, this solution is not good, because all it does is remove the menu bar after the fact. You can still see it for a split second. It's very annoying. Looking at the source code in startup.el I don't see an obvious solution to this problem. I think the only way is to use before-init-hook. Maybe this could do the trick? (add-hook 'before-init-hook (lambda () (setq emacs-basic-display t))) But this hook is run before init.el and other init files are evaluated, so how is one supposed to use it?

  • Windows 8.1 & manual removal of "Sentinel Runtime Drivers"

    - by uos??
    I'm trying to install Windows 8.1 (basic upgrade from Windows 8). It is complaining of Sentinel Runtime Drivers incompatibility. I've looked for it in my Programs & Features list, but it's not there by that name nor SafeNet (as related by google search) nor do I see any obvious candidates for it having been bundled with another listed application. I tried the "Sentinel Runtime Driver Cleanup" program from the SafeNet website. It ran but was ineffective, even after a reboot. Do you recognize this "Sentinel Runtime Drivers"? I ran MalwareBytes too, just in case, but it found nothing.

  • apache2 Webdav using VirtualDocumentRoot

    - by picca
    I'm trying to get up dynamical WebDav on my virtual hosts <VirtualHost *:80> # http://www.example.com/test.txt -> /var/www/example.com/www/test.txt VirtualDocumentRoot /var/www/%-2.0.%-1.0/%-3+/ <Location /webdav> Dav On AuthType Basic AuthName "example.com" AuthUserFile /var/www/[PROBLEM-1]/passwd.dav Require valid-user </Location> </VirtualHost> Is there any way I can set dynamically PROBLEM-1 placeholder based on whatever comes with *HTTP_HOST*? More precisely part of it? Example: HTTP_HOST = www.example.com - PROBLEM-1 = example.com HTTP_HOST = example.com - PROBLEM-1 = example.com What I'm trying to do here is to load dav passwd file dynamically based on which domain is requested. It is something like "groups" if you wish. So that owner of domainA is not allowed to access files of domainB. So maybe there is some other solution based on AuthGroupFile directive?

  • USB keyboard not working under Windows 7 x64?

    - by Comboo
    I have two USB keyboards, one no-name cheap thing and an old Logitech. When I plug them in to my computer they pop up in Device Manager as an "Unknown device" and "USB-receiver", respectively. Both of them fail to install any drivers, neither automatically or through Windows Update. Both keyboards work perfectly on another computer I have with Windows Vista 32-bit. Can this be one of those cases where a device does not work in a 64-bit version of Windows? I doubt it though since I've never had that problem before with any device and I thought that basic things like keyboards would be kind of failsafe. I don't really know how to start debugging this issue. I've tried all the obvious, rebooting, changing the USB port, etc. Are there any generic x64 keyboard drivers you can use? Is there any way to find the manufacturer of the keyboard over USB? There is nothing written on it.

  • If using a bootable Ubuntu USB drive, can I use the internal hard drive as a temporary download and

    - by NoCatharsis
    I am new to Linux, so this is probably a basic problem... My flash drive is only 4GB in size and that is not enough to hold kernel and other package updates, even if only temporary. I am actually using Kubuntu, but I don't think this would change the nature of the question...? I would just like to be able to set my download directory to the internal drive to download the upgrades, then replace the old versions installed on the USB. Of course I have no use for keeping the older versions, so would I also have to manually remove those after upgrading?

  • Modifying the install environment for RH-like installations

    - by javanix
    I am trying to modify the basic installation environment (ie, what Anaconda runs in) for a customized CentOS distribution. For the first try, I would just like to modify a few of the splash images. My initial attempt to do this entailed: 1) Mount images/install.img to a directory ~/img/ 2) Copy all files from img/ to ~/tmpimg/ 3) Modify the splash images 4) mkisofs -o ~/final/install.img 5) cp ~/final/install.img back to my ~/cdroot/ folder and remake the iso. However, the generated .img in step 4 doesn't even come close to matching the file size from the original install.img (meaning that install.img must be created in some other fashion using compression), and it fails when I boot my iso. What settings should I be using to make the install.img file? Is there some other technique for modifying CentOS install environments?

  • .htaccess enabled, but not working.

    - by Aristotle
    I been having some very frustrating issues with getting .htaccess to work on my new server. I'm not very experienced in managing a server, but I've spent the last three days pouring over documentation and every resource I can get my hands on. I've attempted to try a very basic application of .htaccess, and yet it fails to give the expected results. I've setup a test over at http://173.201.185.217/test/. Immediately within this directory is an .htaccess file with the following command: deny from all If I'm not mistaken, this should deny access to /test, but it doesn't. It just sits there allowing anybody to view the contents. What could be wrong with my server/configuration? The server is running CentOS.

  • ADD ROUTE command in windows 2008R2

    - by Mehrdad Kamelzadeh
    I don't know much about Networking, So excuse me if I am raising some basic issues. I have a LAN where there is a Windows Server 2008R2 with some clients connected to it. The clients are not joined to the domain of the Server (they are in a WORKGROUP). I have set up a VPS on the server machine (PPTP) with a Static address pool of range 10.0.0.1 - 10.0.0.10 but the LAN range itself is 192.168.1.1 - 192.168.1.254. When I connect to the server from another location over the internet, I can just see the server and I can not see the other clients which are in the same LAN as the server. what to do to see the other clients? a friend of mine said that you should use the ADD ROUTE command. Beacuse of that I used this command as my title. What would be the best way to address this problem? Thanks

  • How can I send a Wake on Wireless LAN (WoWLAN) / Wake on Demand request manually?

    - by pioto
    This is similar to, but not the same as, http://serverfault.com/questions/1721/is-wireless-wake-on-lan-possible. I know it is supposed to be possible. The question is, how do I do whatever the AirPort Basestation will do? All I can find so far is that supposedly I need to send something with Wireless Multimedia Extensions (WMM): Basically, I want to be able to wake up my Mac Mini remotely, probably using my Linux laptop. Does anyone know of a tool to do this? Basic Wake on LAN tools do not seem to be the right thing. I don't need the Sleep Proxy Service bit, because I already know the MAC address of the system I want to wake up.

  • Is it bad to have a very full hard drive on a high traffic database server?

    - by MikeN
    Running an Ubuntu server with MySQL for a high traffic production database server. Nothing else is running on the machine except the MySQL instance. We store daily database backups on the DB server, is there any performance hit or reason why we should keep the hard disk relatively empty? If the disk is filled up to 86%+ with the database and all of the backups, does it hurt performance at all? So would the DB server running with 86-90%+ full capacity perform less well in any way than the server running with only a 10% full disk? The total disk size on the server is over 1 TB so even 10% of the disk should be enough for basic O/S swapping and such.

  • estimating size of reply HTTP headers

    - by Guanidene
    I am trying to download a file via a basic socket connection, using a HTTP GET request. So, I have to specify how many bytes of data coming in I have to read from the socket. However, I am having trouble deciding the amount of data (say, in bytes) the server would reply back with. I know that there is a "Content-Length" field in the reply sent by server, but that gives me the size of the actual data (without the http headers). Is there a way to get the exact size of HTTP headers sent by the server or an estimation is required? (I am doing this for downloading on a mobile network, where every bit of data matters in terms of time and money, so I don't wish to make an unnecessary larger estimate of the header size.)

  • What is a safe way to dispose of personal info on an old laptop and what to do with said laptop?

    - by MikeN
    I have an old laptop someone gave me that only has 64Megs of RAM on it and runs WIN XP. I wanted to wipe the drive clean by installing Ubuntu Desktop to remove any shred of personal information on it and to make it useful to someone else. But the Ubuntu installer keeps failing because there is not enough RAM. Is there another version of Linux that would easily install on a 64 Megs of RAM system? 2nd part of question, what do I do with this old laptop? It doesn't have a battery anymore and has to be plugged into the wall to run. Assuming I can install a good Linux distro on it, who do I give it to? Salvation Army? I'm looking to just have it be useful to someone or some organization for spare parts or some basic computer usage.
