  • Windows file association for README, INSTALL, LICENSE and the like [closed]

    - by Lumi
    Possible Duplicate: How to set the default program for opening files without an extension in Windows? Many files originating in the UNIX world come without file extension. Popular examples include README, INSTALL, LICENSE. We know for a fact that these are text files. It is therefore a bit disappointing not to be able to just double-click them open in Explorer and see them in Notepad (actually, Notepad2 because of the UNIX line endings which silly Microsoft Notepad doesn't render correctly). Does anyone know of a way to create a file association for, say, README files without extension? This could then be replicated to cover the most frequently occurring file types, and then double-clicking them open would work. Update (Sort of in response to all your comments.) Thanks, folks, your comments and answers have helped me. @Indrek, yes, I was under the assumption that you could somehow create an association for just README or Makefile, and couldn't do so for files without extension. Turns out the contrary is true, and yes, that is a workaround that neatly solves the issue. Ultimately, I just want to be able to double-click to open a README or Makefile, that's all. @Sampo, the SendMe trick is also useful, although usability is not as great as a straight double-click. (I'm really lazy sometimes.) Turns out the following trick using ftype and ftype from an Administrator prompt does the double-click enabling job: assoc .=no_ext ftype no_ext=%SystemRoot%\system32\NOTEPAD.EXE %1 :: You can see it created some entries in the registry: reg query hkcr\no_ext /s reg query hkcr\. /s

  • Requests per second slower when using nginx for load balancing

    - by Ed Eliot
    I've set up nginx as a load balancer that reverse proxies requests to 2 Apache servers. I've benchmarked the setup with ab and am getting approx 35 requests per second with requests distributed between the 2 backend servers (not using ip_hash). What is confusing me is that if I query either of the backend servers directly via ab I get around 50 requests per second. I've experimented with a number of different values in ab the most common being 1000 requests with 100 concurrent connections. Any idea why traffic distributed across 2 servers would result in fewer requests per second than hitting either directly? Additional info: I've experimented with worker_processes values of between 1 and 8, worker_connections between 1024 and 8092 and have also tried keepalive 0 and 65. My main conf currently looks like this: user www-data; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; worker_rlimit_nofile 8192; events { worker_connections 2048; use epoll; } http { include /etc/nginx/mime.types; sendfile on; keepalive_timeout 0; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } I've got one virtual host (in sites available) that redirects everything under / to 2 backends across a local network.

  • SSL Handshake negotiation on Nginx terribly slow

    - by Paras Chopra
    I am using Nginx as a proxy to 4 apache instances. My problem is that SSL negotiation takes a lot of time (600 ms). See this as an example: http://www.webpagetest.org/result/101020_8JXS/1/details/ Here is my Nginx Conf: user www-data; worker_processes 4; events { worker_connections 2048; use epoll; } http { include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; sendfile on; keepalive_timeout 0; tcp_nodelay on; gzip on; gzip_proxied any; server_names_hash_bucket_size 128; } upstream abc { server 1.1.1.1 weight=1; server 1.1.1.2 weight=1; server 1.1.1.3 weight=1; } server { listen 443; server_name blah; keepalive_timeout 5; ssl on; ssl_certificate /blah.crt; ssl_certificate_key /blah.key; ssl_session_cache shared:SSL:10m; ssl_session_timeout 5m; ssl_protocols SSLv2 SSLv3 TLSv1; ssl_ciphers RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP; ssl_prefer_server_ciphers on; location / { proxy_pass http://abc; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } The machine is a VPS on Linode with 1 G of RAM. Can anyone please tell why SSL Hand shake is taking ages?

  • Partitioning & Linux

    - by Zac
    Every tutorial on Linux-based partitioning schemes (or, just partitioning in general) will tell you that a PC can have either 4 primary partitions, or 3 primaries and 1 extended. They will all also tell you that Linux (in my case, Ubuntu) can be installed on either. It's also come to my attention that it is not too atypical for FHS directories, such as usr/, tmp/, etc/, home/ or var/ to be mounted separately on other partitions. Several questions I am unable to find the answers to, purely for my own edification: (1) By "PC", are we really talking about common PC disk types, like IDE or SATA? I guess I'm wondering why PC uses are limited to 4 primaries or 3 primaries + 1 extended (2) I'm choking on some basic OS concepts: it is said that a partition can be mounted by a file system or an OS. So I assume this means I can somehow instruct Ubuntu to mount to 1 partition, and then any part of, say, ReiserFS, to be mounted to another partition? How? (3)(a) What about creating swap partitions? Is there too much of a good thing with swap partitioning? If I have 4GB RAM over 320GB disk, what should my swap partition size be, and why? (3)(b) Are swap files the only way to create swap partitions? Wouldn't a Linux partitioning utility allow me to define a partition as being for virtual memory only? (4) Why are partitions limited to being "mounted" by just OSes and file systems? Why couldn't I write a program to take up its own, say, 512 MB partition, and then have it invoked or uses by an OS installed on another partition? Thanks for shedding any light here... not critical that I know this stuff, but it's got me thinking incessantly. And when I think incessantly, I...can't......sleep....

  • Sane patch schedule for Windows 2003 cluster

    - by sixlettervariables
    We've got a cluster of 75 Win2k3 nodes at work in a coarse grained compute cluster. The cluster is behind a mountain of firewalls and resides in its own VLAN. Jobs of all sizes and types run on the cluster and all of the executables running are custom-made. (ed: additional notes on our executables) The jobs range from 30 seconds to 7 days in duration, and may contain one executable or 2000 sub-jobs (of short duration). Obviously we are trying to avoid the situation where our IT schedules a reboot during a 7 day production job. We have scheduling software which accomodates all of the normal tasks for a coarse grained cluster and we can control which machines are active for submission, etc. If WSUS was in some way scriptable (or the client could state it's availability for shutdown) we could coordinate the two systems and help out. Currently, the patch schedule is the Sunday after Super Tuesday regardless of what is running on the cluster. We have to ask for an exemption every time we want to delay patching a machine for a long running production job. Basically, while our group is responsible for the machines we have little control over IT's patch schedule. Is patching monthly with MS's schedule sane for a production Windows cluster? Are there software hooks in WSUS where we could say, "please don't reboot just yet"?

  • Issues with Apache redirect to www-prefixed URL

    - by lamp_scaler
    I have a website with domain mysite.com. I would like to have it so that if a user types in "mysite.com" it will redirect to "www.mysite.com". Additionally, "mysite.com/subdir" will also redirect to "www.mysite.com/subdir". I've looked and made changes with vhosts and also rewrites, but it's not working for the "mysite.com/subdir"-"www.mysite.com/subdir" case. Every time I type in "mysite.com/subdir", it will redirect to "www.mysite.com". Only "www.mysite.com/subdir" works. Not sure how to troubleshoot this. I turned on rewrite logs and didn't see anything obvious, yet. This is my config files so far. Please let me know what I'm missing. Thanks!

  • Is there a list of Windows services that can be turned off to save resources?

    - by scunliffe
    Every time I open up my task manager and look at the tasks running, it appears to me that there has got to be a bunch of junk running in there that I don't want or need and would be better off turning off (e.g. set the service to manual vs. automatic) In particular I'm running Windows XP, but I'd be interested in services for any version. e.g. Service: ThinkPad PM Service What is it: The ibmpmsvc.exe process is installed by default on IBM Notebook computers. It allows various functions of your IBM notebook to be controlled using the blue Fn keys. If you use the blue Fn keys on your Notebook, you should leave this process running. Otherwise, if it is causing problems for your system you should terminate the ibmpmsvc.exe process. (source) Thus for me, (having never used, or intending to use these buttons) - I want to turn it off. There's lots that just seem painfully unnecessary to me... I'm just not sure which ones I can "safely" stop/disable without issues... "Alerter", "ClipBook", "Messenger", "Telnet", "ATI Hotkey Poller", "Office Source Engine", etc. I'd appreciate any info on services that are truly unnecessary, or only useful to certain people/types of users.

  • Linux Startup Script after Gnome Login

    - by Eric
    I have a Fedora server that I want to spawn an interactive python script after the user logs on. This script will ask the user for various types of information for configuring the system or it will search for the previous config file and show them the predefined information. Originally I was going to put this in rc.local or make it run with init.d but that messed up the boot due to how the script is spawned. So I would like this script to run as soon as the user logs in to Gnome. I've searched around quite a bit and found this answer which appears to be exactly what I want, but it isn't working the way I want it to. Below is my entry. [Desktop Entry] Name=MyScript GenericName=Script for initial configuration Comment=I really want this to work Exec=/usr/local/bin/myscript.sh Terminal=true Type=Application X-GNOME-Autostart-enabled=true Whenever I login, nothing happens. So I then did a test to modified "myscript.sh" to just echo some text to a file and it worked fine. So it appears the portion that isn't working is the script popping open a terminal and waiting for the users input. Are there any additional options I need to add to make this work? I can confirm when I run /usr/local/bin/myscript.sh from the CLI it works fine. I have also tried adding "StartupNotify=true" and still no luck. Edit @John - I tried moving my Exec= to /usr/local/bin/myscript-test and this is what myscript-test contains. #!/bin/bash xterm -e /usr/local/bin/myscript.sh Yet again, when I just run the myscript-test it works fine. However when I put that in my autostart, nothing happens. Edit 2 - I did a few more tests and it did start working but I had to remove Terminal=True before the xterm would pop. Thanks for your help.

  • Using IIS6 to run kill process. Executable hangs

    - by David
    I'm using the following code (any tried many variations) in a web page that is supposed to kill a process on the server: Process scriptProc = new Process(); SecureString password = new SecureString(); password.AppendChar('p'); password.AppendChar('s'); password.AppendChar('s'); password.AppendChar('w'); password.AppendChar('d'); scriptProc.StartInfo.UserName = "mylocaluser"; scriptProc.StartInfo.Password = password; scriptProc.StartInfo.FileName = @"C:\WINDOWS\System32\WScript.exe"; scriptProc.StartInfo.Arguments = @"c:\windows\system32\killMyApp.vbs"; scriptProc.StartInfo.UseShellExecute = false; scriptProc.Start(); scriptProc.WaitForExit(); scriptProc.Close(); The VBS file is supposed to kill a w3wp.exe process, but never works. There are no errors in the application log. It works locally. I noticed WScript.exe is in task manager every time I run the page, and never goes away. The process WScript.exe (and I tried others such a psexec.exe) is being run as a local user with admin rights (and I tried other types of users including domain admins) when run from IIS, but it works when run from the command line on the server.

  • Using NFS for scalable PHP/MySQL web application

    - by Jeroen Moons
    Here's the situation: I have a PHP/MySQL web application that accepts user uploads (pdf files). From these pdf files' pages a preview image is made on the fly and presented to the web app's users. Some pdfs might be on the large side, most will be under 50 MB but some extreme cases could be as large as a few hundred MB. A little waiting for the preview image for large pdf files is acceptable but no more than a minute let's say. Everything is running on one server for now, but soon the app will hit the server's limit on both storage and processing power. My idea to solve the problem: To deal with this situation I had the idea of having one or more pdf processing servers as needed, and one or more file storage servers. These two types of servers are mounted to the server on which the actual app runs using NFS. The app could then use GearMan to delegate pdf processing tasks to these processing servers. The processing server can mount the storage server and read the file stored there, process it and write its output to that server. The servers I'm talking about will be amazon ec2 instances. The web app returns a link to the resulting pdf preview image on the storage server that was used which can then be used on the front end to show the image to the user. My question: I have zero experience with apps that use multiple servers, is this idea viable or is there a better way to do it? Is an NFS setup fast and reliable enough for this situation?

  • Trouble with nginx and serving from multiple directories under the same domain

    - by Phase
    I have nginx setup to serve from /usr/share/nginx/html, and it does this fine. I also want to add it to serve from /home/user/public_html/map on the same domain.

  • Apache2: Limit simultaneous requests & throttle bandwidth per IP/client?

    - by xentek
    I want to limit simultaneous requests & throttle bandwidth per IP/Client on a single apache vhost. In other words, I want to ensure that this site, which hosts large media files, doesn't get hammered by someone trying to download everything all at once (just happened the other night). I'd like to limit the outgoing transfer speed overall for this site, as well as limit the number of connections a single IP can make to the server to a sane default (i.e. within normal browser limits for multiple requests so page loads aren't effected too much). Bonus points if I can actually scope it to file types (i.e. leave web files alone, but apply these rules to just the media files). We're running Ubuntu 9.04 on all the servers, and have two apache/php servers being load balanced via Round Robin by a squid proxy server. MySQL is running on its own box as well. We've got plenty of bandwidth to give them, so I don't really want overall caps, but just want to throttle the amount of memory/CPU it takes to serve this site. There other sites on these servers that we don't want to apply these rules too, just want to keep this one from hogging all the resources. Let me know if you need more info! Thanks in advance for your suggestions!

  • Windows 7 Professional Cannot Connect to Share - Wrong password

    - by henryford
    I know that this question has actually been asked a few times before, but every solution I found didn't yield any results on my end, I can't get my head around it: When I am trying to connect to a share on the network, I always get the response "The specified network password is incorrect". However, the password is definetly correct and it works if I connect from another machine. I changed the LAN Manager authentication level to "Send LM & NTLM - use NTLMv2 session security if negiotated", I configured Kerberos encryption types to include all suites, rebooted (several times), but still - no luck. I can connect if I use my regular account with which I am logged in, but I need to connect with a different user since my log-in user has not enough privileges on the share. When I do that, the error above comes up. I'm really frustrated at the moment, this problem is driving me crazy. I'd be gladful for any possible solution to this. At the moment I'm using a workaround: I connect to a different machine via RDP, login with the user I have to use for the network-share connection and then I can map the drive and copy/paste from the RDP session to my local workstation. This is also working when I am connecting via RDP with my current login user and map the drive with the other user who has sufficent privileges. Tanks in advance, Thomas

  • Windows desktop virutalization instead of replacing work stations

    - by Chris Marisic
    I'm head of the IT department at the small business I work for, however I am primarily a software architect and all of my system administration experience and knowledge is ancillary to software development. At some point this year or next we will be looking at upgrading our workstation environment to a uniform Windows 7 / Office 2010 environment as opposed to the hodge podge collection of various OEM licensed editions of software that are on each different machine. It occurred to me that it is probably possible to forgo upgrading each workstation and instead have it be a dumb terminal to access a virutalization server and have their entire virtual workstation hosted on the server. Now I know basically anything is possible but is this a feasible solution for a small business (25-50 work stations)? Assuming that this is feasible, what type of rough guidelines exist for calculating the required server resources needed for this. How exactly do solutions handle a user accessing their VM, do they log on normally to their physical workstation and then use remote desktop to access their VM, or is it usually done with a client piece of software to negotiate this? What types of software available for administering and monitoring these VM's, can this functionality be achieved out of box with Microsoft Server 2008? I'm mostly interested in these questions relating to Server 2008 with Hyper-V but fell free to offer insight with VMware's product line up, especially if there's any compelling reasons to choose them over Hyper-V in a Microsoft shop. Edit: Just to add some more information on implementation goals would be to upgrade our platform from a Win2k3 / XP environment to a full Windows 2008 / Win7 platform without having to perform any of that associated work with our each differently configured workstation. Also could anyone offer any realistic guidelines for how big of hardware is needed to support 25-50 workstations virtually? The majority the workstations do nothing except Office, Outlook and web. The only high demand workstations are the development workstations which would keep everything local.

  • Home Server: storage virtualisation, what to choose?

    - by Huygens
    I'm looking for virtualisation solutions for storage and OS for a home server. A sort of private cloud where I manage the storage space independently of the VM one. This question focus on storage management. (I have another question related to the VM/compute instance management). Here my environement and wishes. Server: HP Proliant MicroServer with 8 GB RAM (AMD Turion dual core with AMD-V technology) with 1 250GB system disk and up to 4 HDD (2 TB) for "data" OS types: only Linux (perhaps a *BSD VM in the future) Linux distributions do not matter, I'm familiar with RHEL, Fedora, Suse, Ubuntu, but any other recommandation will be fine The 4 HDD is going to be a software RAID array, probably RAID 5. storage should be "virtualised/cloudified": easy to extend: if I add a NAS on the network, I can include the NAS space capacity within this storage space as one virtual disk. This can be a NAS, an external HDD or another server. cluster FS or S3 style space or OpenStack block storage? Whatever is easier to manage/maintain and easy to integrate/plug to VM/compute instance. I would prefer free (libre, as in a free speach) and open source tools. But it does not have to be free as in a free beer. Note: the VMs I intend to run on top of this server are one dedicated to backup, one for a "owncloud/dropbox"-like service and perhaps one for media server (hosting video and photos). I'm not sure if traditional VMs or compute instance are the most suitable for this.

  • Suddenly getting lock timeouts with MySQL

    - by Marc Hughes
    We've got a web app hosted on Amazon Web services. Our database is a multi-az RDS MySQL server running 5.1.57 and 3-4 app servers talk to it. Today, we started seeing a lot of errors along the lines of "Lock wait timeout exceeded; try restarting transaction" - almost 1% of POST requests are seeing this. There have been no modifications to the code running on the site. There have been no schema changes. We haven't had a big spike in traffic. I've been looking at the processes running, and none seem out of control. I tried scaling our RDS instance from a small to a large, with no effect. Two days ago, Amazon had some outages. As part of the recovery from that, our RDS server, and our app servers ended up in different availability zones, but all within the same region. But yesterday, everything was fine so I'm not convinced that's related. The lock timeouts are in different types of requests and occur in different InnoDB tables. I have noticed the number of open connections jumped when we started seeing problems, but they may be a symptom and not a cause. What are my next steps in debugging this?

  • What does "incoming" and "outgoing" traffic mean?

    - by mgibsonbr
    I've seen many resources explaining how to set up a server's firewall to allow incoming and outgoing traffic on HTTP standard ports (80 and 443), but I can't figure out why I would need either of them. Do I need to unblock both for a "regular" web site to work? For file uploads to work? Are there situations where it would be advisable to unblock one and leave the other blocked? Sorry if that's a basic question, but I couldn't find it explained anywhere (also I'm not a native english speaker). I know in a "regular" web site the client is always the one who initiates a request, so I'm assuming a web server must accept incoming traffic on those ports, and my common sense tells me the server is allowed to send a response without unblocking anything else (otherwise it wouldn't make sense to have two types of rules). Is that correct? But what is an outgoing web (service) traffic, and what would be its use? AFAIK if the server wanted to initiate a connection with another machine, the specific port that matters is the one in the other end (i.e. the destination port would be 80), on its end any free port could be used (the source port would be random). I can open HTTP requests from my server (using wget for instance) without unblocking anything. So I'm assuming my concepts of "incoming" and "outgoing" are wrong somehow.

  • Outlook 2007 + Exchange 2010 (Save All Attachments)

    - by RobertPitt
    About 3 weeks back our company upgraded our mail system to Exchange 2010, all went smooth, few issues but nothing major. A few days ago we had a call from a colleague where he was unable to save all attachments, From File > Save As > Save All Attachments. When the email has a single attachment it works perfectly normal, and depending on the file type it allows you to save multiple attachments. But there's a lot of file types that will not work, such as zip, pdf, doc etc, Usually we get a location box open up asking where we would like to drop the attachments, but it does nothing, You click Save All Attachments and nothing happens. After hours of research I have come across mixed results, a lot of people on forums have been explaining that they have recently crossed over to Exchange 2010 and there issues started there. But on the other hand Microsoft released a KB (278188) which was depressing if that, but that article was published in 2007, as stated by the time stamp, and Exchange 2010 has only come out recently. Im looking to see if you guys have any clues what could be causing this, anything server side that I can take a look at (AD, Exchange, ...). Any help on this is greatly supported

  • Winamp has slow /skipping video playback on Windows 7

    - by Roy Rico
    Hello, I have Windows 7 x64 (7600 90-day trial version) and Winamp 5.6 installed. When I play a video in Windows Media Player, the video plays smooth, however when I play a video in winamp, the video is mostly ok when played back at the original size (but not completely), but if I play it back in fullscreen, the playback gets really slow. The video's audio track plays just fine. I have a DELL XPS 420 computer (8GB of RAM) with a Nvidia GeForce 8800 CTS 512 video card. I've updated to the latest drivers. I have the default Windows 7 codecs, and the CCCP codec pack which used to be all I needed under Windows XP to play all types of videos. Are the codecs needed for Windows Y the same? What's going on? UPDATE: As suggested, I turned off Aero and winamp ran just fine again. So I just have to wait for winamp to be rewritten to work with the way Vista/Windows 7 runs? UPDATE 2: Winamp has updated their player, and it works great with Windows 7 now.

  • Nginx + Ubuntu 9.10, gzip not functioning

    - by Matt
    Hey there, So I installed and configured Nginx 0.7.62 on a new Slicehost Ubuntu 9.10 slice. All seems to work fine with the server, except that gzip isn't working for one reason or another. I made sure that it's setting were correct in /etc/nginx/nginx.conf: user www-data; worker_processes 3; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; # multi_accept on; } http { include /etc/nginx/mime.types; access_log /var/log/nginx/access.log; sendfile on; #tcp_nopush on; keepalive_timeout 2; tcp_nodelay on; gzip on; gzip_comp_level 2; gzip_proxied any; gzip_types text/plain text/css application/x-javascript; gzip_disable "MSIE [1-6]\."; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } This normally wouldn't be a big deal, but gzip support could save considerable bandwidth for my site. Does anyone have any ideas of what to check, or has anyone else run into this problem?

  • Web Hosting: Any web host that supports files more than 50,000 in number?

    - by Devner
    Hi all, For my PHP & mySQL based application, I am trying to buy website hosting from a host who does not have a limit on the number of files I carry in my hosting account. Almost all the websites have a common limit of 50,000 files (some websites call it 50,000 nodes). The rest(to the extent of my search) are not even close. I have gone through the various websites, Googled lot of information, have spoken with the customer service of the hosting companies and they said that they have a limit of 50,000 files and that's why they call it the LIMIT. Now I have my application, which is a kind of social networking website, where people can upload various files of varying file size. So say if 50,000 users were to join the website and upload 1 file each, the limit of 50,000 will be reached very easily and my 50,001 customer will start facing file upload problems (& so will my account). So I would like to know if there's any website hosting services that do NOT levy such restrictions. In summary, I need the following options: No maximum file limit (more than 50,000 files in account). No maximum file upload limit in server setting (10MB, 12MB, 15MB, 20MB, etc.). Ability to upload files of various types (zip, flv, jg, png, etc.). Ability to stream Audio and Video (live audio & video not necessary). Access to .htaccess Access to php.ini, my.cnf or my.ini (this would be a plus) Supports SSL. Provides dedicated hosting(& IP) as well. Monthly payments without contracts are a plus. If you know of any such website hosting services, please post a reply ( a link to the same will be appreciated ). Thank you.

  • Windows 7 System File Checker (sfc) not working

    - by Andrew
    I have a strange problem with Windows 7 RTM. I'm running Ultimate 64-bit edition. Whenever I run sfc /scannow I get this error: Windows Resource Protection could not start the repair service. My research so far has told me that I need to set the Windows Module Installer and Windows Installer services' startup types to Manual. They already were, so I manually started those services and tried again. No luck. I've even booted into my Windows 7 repair disc and tried running sfc /scannow from that. All I get is this: A repair operation is already pending. Restart and try again. History: I'm trying to run sfc because I am unable to open any images in Windows Photo Viewer. Whenever I try, I get the error "Class not registered." I believe the problem started after I installed Gladinet, but I can't be sure. I've uninstalled Gladinet, but the problem remains. System Restore was disabled (yes, I know I'm stupid - you don't have to remind me). Please help. Thanks.

  • How do I get ftype & assoc to match Windows Explorer?

    - by Gauthier
    I changed the association to use upon launching a .py file, via Windows Explorer: Tools - Folders - File types. Then browse to .py. Change the association to Wordpad. Now when I type the name of a py file in the command line, Wordpad opens it. But assoc and ftype in the command line still return the following: C:\> assoc .py .py = Python.File C:\> ftype Python.File Python.File = "C:\Program\Python27\python.exe" "%1" %* How come the association is working, but assoc and ftype are not aware of it? I did restart the prompt. More info from my registry: HKEY_CLASSES_ROOT\.py = Python.File HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\Application = wordpad.exe HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\OpenWithProgids\Python.File = HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.py\(Standard) = Python.File More registry: HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command\(Standard) = "C:\Program\Python27\python.exe" "%1" %*` I suppose this is what is showing up in ftype Python.File. But it does not seem to get used. (I am doing this for testing, so I can eventually choose my default version of Python easily).

  • Nginx order of servers

    - by scrat
    I have 3 sites on my server. All are running on gunicorn and use unix sockets to communicate with nginx which routes requests. I got three records in nginx.conf like: server { listen 80; server_name site1.com; location / { proxy_pass http://unix:/tmp/site1.sock; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } For site1, site2, site3. If they are ordered as config for site1 goes first, and then goes config for site2 and site3 everything works good. But when I change the order for example to site2, site1, site3, then site1 becomes routed to site2. What am I doing wrong? Full server nginx.conf before servers configs: user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_types text/css application/x-javascript text/x-component text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;
