  • Can a cur file have an alpha map (for high quality transparency)?

    - by Codemonkey
    I want to convert this Heroes of Newerth cursor into a cur file so I can use it as a cursor on windows and on my website. The cursor is now in a PNG file with an alpha map, and I have so far been unsuccessful in converting it to a cur file. The things I've tried is using the Photoshop cursor plugin to simply save the png as a cur. The result was a working cur file with a white background instead of a transparent one. I've also tried painting the background pure green (0, 255, 0) and saving as a cur file, in which case the background was still green when I tried using it as a windows cursor. I've also tried what's been mentioned in a few tutorials, which is selecting the area I want transparent and saving the selection in Photoshop (it then ends up as a new channel). So I selected the cursor and inverted the selection and saved it. The result was a bit odd. Instead of a transparent background, I now get a background that inverts the colours behind it, just like the "Windows inverted" mouse scheme. So is there any way to accomplish what I'm trying to do?

  • How to write rules for persistent net names?

    - by ndemou
    I know that a process generates persistent network card names based on rules found in /lib/udev/rules.d/75-persistent-net-generator.rules. I also know how to completely disable this process with a simple echo '#' > /etc/udev/rules.d/75-persistent-net-generator.rules but I've read that I "could also write my own rules file to give the interface a name — the persistent rules generator ignores the interface if a name has already been set" (/etc/udev/rules.d/README confirms that this is possible). Do you have any pointers to documentation about how to write such rules? (I mostly care about Debian/Ubuntu and a bit less for CentOS) As a specific example of why I want to write custom rules: I have two identical servers with one onboard LAN and one PCI LAN. In case of HW failure I want to be able to move disks from HW#1 to HW#2 and it's important for eth0 to continue pointing to the onboard card and eth1 to the PCI card (no one wants to mess with cabling in the middle of a HW failure panic). My current workaround works but is a lot of work[1] so I wonder if writing custom rules would allow me to express something simple like this: cards with MAC A or B should be named eth0 cards with MAC C or D should be named eth1 follow default naming scheme for anything else [1] install the OS in HW#1 and keep a copy of /etc/udev/rules.d/70-persistent-net.rules. Move the disks to HW#2 and keep a second copy of the same file. Concatenate the two copies and manually edit the NAME="ethX" part. Replace /etc/udev/rules.d/70-persistent-net.rules with my version. Finally disable auto-creation of a new 70-persistent-net.rules using echo '#' > /etc/udev/rules.d/75-persistent-net-generator.rules

  • Connect Ralink RT2571 to new PC

    - by tuelsch
    I bought a new PC with the AsRock Z77 Extreme 4m motherboard, since this has no WLAN, I extracted the WLAN card from my old PC, a Ralink RT 2571 WF, an connected it to the new board. I downloaded the driver from http://www.ralinktech.com/en/04_support/support.php?sn=500 (the RT257x USB one) and installed it. In the device manager, an unknown device shows up, but if I tell it to search its driver, it does not find it (searching in the whole C partition). The Ralink Diagnostic Test says that the WLAN Card is disabled. I'm using Windows 7 64bit professional. Can anyone suggest me a solution to get my WLAN running?

  • Storage drives is causting system crash

    - by Chad
    I'm running Centos 5.4 with 750GB(ntfs) and 2TB drives for storage. Originally I installed the 750, everything seemed fine and then I installed the 2TB drive with NTFS already partitioned. I noticed when I would copy a lot of videos it would crash (no mouse or response from server) about 20min into it. After doing some troubleshooting I noticed the 750 would also crash when doing the same task so I decided that NTFS may be the problem. I unmounted the 2TB drive and tried to partition and format it using ext2 but when using parted it would crash at this point "writing inode tables". Looking at the dmesg logs I believe this is the error "mtrr: type mismatch for e0000000,10000000 old: write-back new: write-combining". Any idea as to what could be causing this?

  • HTTPS Proxy which answers CONNECT with own certificate

    - by user1109542
    I'm configuring a DMZ which has the following Scheme: Internet - Server A - Security Appliance - Server B - Intranet In this DMZ I need a Proxy server for http(s) connections from the Intranet to Internet. The Problem is, that all Traffic should be scanned by the Security Appliance. For this I have to terminate the SSL Connection at Server B, proxy it as plain http to Server A through the Security Appliance and then further as https into the Internet. An encryption is then persistent between the Client and Server B and the Target Server and Server A. The communication between Server A and Server B is unencrypted. I know about the security risks and that the client will see some warning about the unknown CA of Server B's certificate. As Software I want to use Apache Web Servers on Server A and Server B. As first step I tried to configure Server B that it serves as endpoint for the SSL Encryption. So it has to establish the encryption with the client (answering HTTP CONNECT). Listen 8443 <VirtualHost *:8443> ProxyRequests On ProxyPreserveHost On AllowCONNECT 443 # SSL ErrorLog logs/ssl_error_log TransferLog logs/ssl_access_log LogLevel debug SSLProxyEngine on SSLProxyMachineCertificateFile /etc/pki/tls/certs/localhost_private_public.crt <Proxy *> Order deny,allow Deny from all Allow from 192.168.0.0/22 </Proxy> </VirtualHost> With this Proxy only the CONNECT request is passed through and an encrypted Connection between the client and the target is established. Unfortunately there is no possibility to configure mod_proxy_connect to decrypt the SSL connection. Is there any possibility to accomplish that kind of proxying with Apache?

  • Grub loading, please wait. . . Error 22

    - by Aexyn
    Yesterday I got a problem which I posted here. Trying to solve it, I installed slitaz live CD to desktop. After that I tried to use boot other live CD's (Ubuntu, Tiny core) but they didn't boot. So I deleted the the slitaz partition through gparted(or something like that) and restarted. After that I am seeing this error message:` GRUB Loading stage 1.5. Starting cmain() ... GRUB loading, please wait... Error 22` UPDATE: I have tried Backtrack live CD to live boot laptop but that doesn't work too.

  • Deleted All Snapshots, Now Won't Boot VM with Snapshot not found error

    - by Jharwood
    I've just tried deleting the snapshots from this virtual machine running ESXI5, so that I can grow the Thick Partition. I've now got the below error message when I try to start the VM, the VM also can't be grown above 0 MB i assume for the same reason as below. I've checked the datastore and the original VMDK is still there. Reason: The system cannot find the file specified. Cannot open the disk 'VM1-PG-000002.vmdk' or one of the snapshot disks it depends on. VMware ESX cannot find the virtual disk "VM1-PG-000002.vmdk". Verify the path is valid and try again. How do i tell ESXI5 to use the proper VMDK?

  • Skipping nginx PHP cache for certain areas of a site?

    - by DisgruntledGoat
    I have just set up a new server with nginx (which I am new to) and PHP. On my site there are essentially 3 different types of files: static content like CSS, JS, and some images (most images are on an external CDN) main PHP/MySQL database-driven website which essentially acts like a static site dynamic PHP/MySQL forum It is my understanding from this question and this page that the static files need no special treatment and will be served as fast as possible. I followed the answer from the above question to set up caching for PHP files and now I have a config like this: location ~ \.php$ { try_files $uri =404; fastcgi_cache one; fastcgi_cache_key $scheme$host$request_uri; fastcgi_cache_valid 200 302 304 30m; fastcgi_cache_valid 301 1h; include /etc/nginx/fastcgi_params; fastcgi_pass unix:/var/run/php-fastcgi/php-fastcgi.socket; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/example$fastcgi_script_name; fastcgi_param HTTPS off; } However, now I want to prevent caching on the forum (either for everyone or only for logged-in users - haven't checked if the latter is feasible with the forum software). I've heard that "if is evil" inside location blocks, so I am unsure how to proceed. With the if inside the location block I would probably add this in the middle: if ($request_uri ~* "^/forum/") { fastcgi_cache_bypass 1; } # or possible this, if I'm able to cache pages for anonymous visitors if ($request_uri ~* "^/forum/" && $http_cookie ~* "loggedincookie") { fastcgi_cache_bypass 1; } Will that work fine, or is there a better way to achieve this?

  • PassEnv does not find ENV variables

    - by quodlibetor
    I've got this /etc/profile.d/myfile.sh: export MYVAR=myval I also have a PassEnv MYVAR line in a <virtualhost> section of an apache conf dir. That lets me do things like: $ echo $MYVAR myval $ python >>> import os; os.getenv('MYVAR') 'myval' $ sudo echo $MYVAR myval $ sudo -i root# echo $MYVAR myval But then, despite that being the case I get: root# /sbin/service httpd restart /sbin/service httpd restart Stopping httpd: [ OK ] Starting httpd: [Mon Oct 22 14:44:02 2012] [warn] PassEnv variable MYVAR was undefined [ OK ] And all of my attempts to access MYVAR from within my wsgi scripts just don't work. Thoughts? Am I doing something obviously wrong? EDIT for more detail I've got a swarm of computers/VMs and a swarm of developers working on a swarm of projects. I need a simple central place to keep environment information, the most common is the "environment" (dev/stage/prod). The scheme that we've got (modifying *.wsgi programmatically) is turning out to be more fragile than we'd like. The main options that I see are: put things in the shell environment put things in other config files Getting things into the shell environment is the best, because we won't need to write yet more duplicated "what is my environment" code.

  • Removing 'bundled' software to make a slow laptop faster?

    - by spdegabrielle
    My brother-in-law has a cheap HP laptop used by his kids for schoolwork. It had got into a bit of a state and was running slowly with some dubious software. I removed a bunch of stuff that had been installed, that was obviously not required (three different driver scanners!), had been downloaded in error or looked like malware. I also disabled as many 'start on login' apps as I could and removed AVG replacing it with MSE. (AVG is uninstalled and replaced with MSE after failing to detect malware) What remains is a significant quantity of bundled HP and 'nero backup' software, including a HP restore utility (apparently something like the osx hidden partition restore), the trackpad driver. is there anything else I can do to breath a little more life into the old 'celeron' laptop? Should I bit the bullet and just put win8 on it? Will the trackpad still work?

  • Linux cannot see Windows 7 partitions on install

    - by Nash0
    I've been trying to install Linux as a dual boot with Windows 7 on my Dell latitude e6510. It is currently running Windows 7 and I have used the MS disk tools to shrink the Win 7 NTFS partition to make room for Linux. The issue I'm having is that when I run Linux installers by boot from CD they see the entire hard drive as unallocated space. I have tried Ubuntu 10.10, Kbuntu 10.10 and Fedora 14 and they all have the same problem. I have also tried the Ubuntu "install in Windows" option and could not get it to work. EDIT: Booting Gparted 0.8.0 from a usb drive did not work. It reported the entire drive as unpartitioned.

  • How can I delete Time Machine files using the commandline

    - by Tim
    I want to delete some files/directories from my Time Machine Partition using rm, but am unable to do so. I'm pretty sure the problem is related to some sort of access control extended attributes on files in the backup, but do not know how to override/disable them in order to get rm to work. An example of the error I'm getting is: % sudo rm -rf Backups.backupdb/MacBook/Latest/MacBook/somedir rm: Backups.backupdb/MacBook/Latest/MacBook/somedir: Directory not empty rm: Backups.backupdb/MacBook/Latest/MacBook/somedir/somefile: Operation not permitted There are a number of reasons I do not want to use either the Time Machine GUI or Finder for this. If possible, I'd like to be able to maintain the extended protection for all other files (I'd like not to disable them globally, unless I can re-enable once I've done my work).

  • What's the best way to be able to reimage windows computers?

    - by mos
    I've got a low-end machine for testing our software. It needs to be tested under various versions of Windows, so I was planning installing each one on its own partition. Then I realized that after testing our software, I'd want to roll back to the previous, clean state. I don't want to use any virtualization software because it tends to interfere with the workings of our app. That said, what's the best way to achieve my goal? Norton Ghost? Edit: I work for a pretty monstrously huge organization. Money is no object here (and sometimes, if the wrong people get wind of it, "open source" software is bad).

  • Where to look for regular scripts?

    - by fontan
    It seems to me that our server freezes every 30 days around noon due to the huge utilization of xvda data transfer partition - writes are 50 times higher than normally (according to the health monitor in plesk). This seems to me as the reason why the apache & co becomes instable as (for example) all apache's processes are waiting to write their log (according to the service's full status). I am, however, unable to find any scheduled task that would be executed during that period. I have checked both cron and anacron setup and there is only one monthly anacron task which is not executed (according to the /var/log/cron - and there is nothing unusual) around noon. Are there any other places where to look for periodical processes? (I am just about to ask server's provider the same question about any external maintenance run around this time but I don't expect them to run anything time/resource consuming during the day.)

  • Minimal backup for Windows 7 system recovery [migrated]

    - by JIm
    There might not be an answer to this, but for a home Win7 system, what files/directories must be backed up to recover after a windows crash? I can reinstall software, and I keep data files elsewhere. When I use acronis home backup software to backup my "critical" files it seems to choose the entire partition. Updates are mostly browser cache files and the like. Or, after a crash, should I just reinstall windows. I dread the hours of windows updates that would require. Thanks.

  • Visual Studio Development on Virtual Box, Boot Camp, or VMWare Fusion

    - by Eli
    I currently have a Mac, 2ghz and 2 gigs of ram, running OS X Leopard and Virtual Box with a Windows 7 Pro 32bit virtual machine. Performance on the virtual machine is fine for minor tasks but is very clunky while trying to multi-task or develop in Visual Studio 2008. What would be my best option for being able to use Visual Studio, keeping cost and time in mind? 1) Upgrade ram to 4 gigs ($100). Will this really improve my performance enough to use Visual Studio in a Windows 7 vm? Or am I just wasting time/money? 2) Reinstall/restore Windows 7 disk image as a Boot Camp partition. I assume this should improve my performance, yes? 3) Purchase VMWare fusion instead of VirtualBox. Does Fusion require less resources to run? I am open to any suggestions. Thanks in advance

  • How can I restore GRUB without a live CD?

    - by Looterguf
    I realize that this is a duplicate of a question asked before, but in that question the asker managed to find his live CD and no real answer appeared, thus I am re-asking it. I managed to screw up my GRUB by deleting two linux partitions on my hard drive from windows. After this, GRUB gives the error "partition not found", and gives me the grub-rescue prompt. The only command I have found to work in this is 'ls', which spits out my partitions. I would use the live CD fix, but I am in India, and all my live CDs are back home in the US... What I've got is an internet connection, a 4GB flash drive with Flow OS installed (which I am currently using but can wipe if need be), and a working laptop that I can borrow. What should I do?

  • Can software operation damage an SD card?

    - by Borek
    My SD card has a broken boot sector and the tools I've tried say that it's not repairable (I've tried TestDisk, DriveRestore Pro and Easeus Partition Recovery). The card was in my Android phone and at one point, it simply shut down and I had to reboot it. After I rebooted it, the SD card was not recognized and since then I've tried to recover it (I don't want to format the card as it contains some data I'd like not to lose although it's nothing critical). My question is, can some software error in Android, or a sudden crash of a system, damage the SD card? Or was it the other way around, the card first died and it brought the system down?

  • Development environment clean installation

    - by ruigoncalves
    Hi there! I'm about to install a new and clean development environment. To accomplish that, I would like a Windows operating system (possibly Windows 7) and a Ubuntu one (possibly the most recent, 10.04). To allow sharing data between the two operating systems, I'm thinking to create a partition (workspace, for example) with using NTFS to format it and that be automatically mounted by Ubuntu. In terms of the partitioning schema, how would be better to organize the previous mentioned partitions? Thanks in advance, Best regards!

  • how to restore windows 7 to a know working state every time it boots

    - by Artanis
    A couple of days ago my mother asked me to set up a computer at his house, she wants to use it to basic web browsing, video chat and nothing more. The problem is, neither my mother nor my sister know anything about using or maintaining a computer. What I want is to have a working base install of windows 7 and just discard everything installed, downloaded, ... when it reboots. That way I can set up a partition just for saving files and whatever they do the computer will always return to a working state at start up. can that be done? PS: Sadly linux is not an option since my sister wants to be able to play some games with my steam account and not all of them run with wine.

  • Running commands on FreeBSD Live CD

    - by jmc
    I'm running FreeBSD 9.1-PRERELEASE on a vps running on XEN virtualization, I tried to update it to 9.1-RELEASE but mergemaster toasted my /etc/master.passwd and /etc/passwd so what i have now is a blank copies of the two files. What i did is use a mounted Live CD and mount my root partition to /mnt and manually re listed every entry to /mnt/etc/master.passwd and /mnt/etc/passwd from another freebsd server. I believe that everytime you edit master.passwd and passwd you have to run pwd_mkdb but this gives me "Read Only File" error. What I plan to do is enable PermitRootLogin and PermitEmptyPassword first so I can login as root first before I redo necessary changes again. But i have to run pwd_mkdb, so is there a way to run this command from Live CD?

  • How do I delete Windows.old in Windows 7?

    - by CRK
    I used to run Windows 7 32 bit, but installed the 64 bit version because of a RAM upgrade. During the installation I got this message: The partition you selected might contain files from a previous Windows installation. If it does, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will not be able to use your previous version of Windows. The C:\ drive now has two (2) Windows folders: Windows (15.3 GB) Windows.old (15.7 GB) Don't see why I need the Windows.old taking over 15GB of space on my hard drive so I tried to delete it. It didn't work. How can I safely delete this folder?
