• how to setup a ssh acount with no terminal but port forwarding?

  - by admalledd

  I am trying to set up a new user account I can give to friends so they can SSH into my forward computer, and only allow forwarding of certain ports. I do not want my friends to have a shell, or be able to change what ports to where they are allowed to forward. example session: joe(friend) connects using PuTTY (that I have pre-set, he isn't good with computers) to example.com(my Internet facing computer) forwarding ports 8080,1990,25565 to him(with what ever end ports he wants, preferably they stay the same numbers) example ssh command to do similar (but he can still change the ports on my computer!) ssh -N [email protected] -p443 -L8080:192.168.1.2:8080 -L1990:127.0.0.1:1990 -L25565:127.0.0.1:25565 then, same story with other friend smith(same ports, same user even) except he is using linux, so cant use putty. is it possible to also leave default SSH functinality for all other users but this one? I found this when I was searching google, but alas, I did not quite understand what was being suggested, and I don't think they covered restricting port forwarding

• Map path server with workgroup to other server with domain

  - by bzamfir

  I have the following situation, and I need some help to setup properly I have two VPS (hosted with the same provider, maximumasp). Server A is 2008R2, set with WORKGROUP, and server B is 2012, set with domain, maximumasp.local. On server A I have an old web app, which uses a special folder, c:\MyUploads, to store uploaded files. App is using this using an appSetting. It will be kept running for a while for safety / compatibility reasons. I installed a new version of the application on server B, running under AppPoolIdentity. Both instances of the app (A and B) will connect to the same database, so I need them to share also the access to upload folder c:\MyUploads. How should I setup the app on machine B to access the folder c:\MyUploads ? My idea is to share the folder as \A\MyUploads, and then map it to server B. But the problem is, I don't know to give Read/write to c:\MyUploads on machine A to IIS AppPools\ on machine B I was trying a test, and shared the c:\MyUploads to Everyone, ReadWrite. I was able to access it from machine B using \\MyUploads But when app from machine B tried to access a file, it gave error. Any idea how can I accomplish this? Some advice on best practices for such situation would be great. Thank you

• DNS point to server on ISP and keep shared host too?

  - by Dwayne

  I know this is probably quite easy to do, but I might just have the right search sorted out... so here is the situation: We have example.com set up as a hosted server along with app1.example.com, app2.example.com and a few others. What I would like to do is set up the right zone file to also make our internal server addressable from the outside world as internalapp.example.com. This server sits behind a firewall (pfsense) and is hooked up to the world via a cable modem that is technically on DHCP from our ISP, but has had the same external IP for the past 15 months so far. What would be the best way to set this up?

• Is Apache ReverseProxy to Passenger Standalone an acceptable production deployment?

  - by davetron5000

  I have the need to deploy Rails 3 apps, using RVM and gemsets, and am expecting “public” traffic (i.e. this is not an internal-only app). I also must use Apache as the public interface to my app. I understand that Passenger Standalone can help accomplish the rails/RVM end, and I have successfully set it up in my development environment. My question is how viable this setup is for a production deployment. Is deploying via Apache configured to ReverseProxy to my passenger-powered Rails app going to create problems? Since I'm designing the production deployment now, I want to understand if I should spend the additional time to set up Passenger connected to Apache and have that Passenger communicate with Passenger Standalone instance running my Rails app. So, I'm looking for one of I guess three answers: Apache Reverse Proxy to Passenger Standalone will be generally fine You should not use the Apache/Passenger Standalone configuration, but set up Passenger on the Apache side as well Your entire setup is just Wrong, please RTFM (and include link to "FM")

• haproxy + nginx: https trailing slashes redirected to http

  - by user1719907

  I have a setup where HTTP(S) traffic goes from HAProxy to nginx. HAProxy nginx HTTP -----> :80 ----> :9080 HTTPS ----> :443 ----> :9443 I'm having troubles with implicit redirects caused by trailing slashes going from https to http, like this: $ curl -k -I https://www.example.com/subdir HTTP/1.1 301 Moved Permanently Server: nginx/1.2.4 Date: Thu, 04 Oct 2012 12:52:39 GMT Content-Type: text/html Content-Length: 184 Location: http://www.example.com/subdir/ The reason obviously is HAProxy working as SSL unwrapper, and nginx sees only http requests. I've tried setting up the X-Forwarded-Proto to https on HAProxy config, but it does nothing. My nginx setup is as follows: server { listen 127.0.0.1:9443; server_name www.example.com; port_in_redirect off; root /var/www/example; index index.html index.htm; } And the relevant parts from HAProxy config: frontend https-in bind *:443 ssl crt /etc/example.pem prefer-server-ciphers default_backend nginxssl backend nginxssl balance roundrobin option forwardfor reqadd X-Forwarded-Proto:\ https server nginxssl1 127.0.0.1:9443

• How to dump the Subject Alternative Name (SAN) from an SSL certificate file

  - by LonelyPixel

  I know that I can dump the entire information from a PEM certificate file with this command: openssl x509 -in certfile -noout -text And I've already found another direct parameter to show me only the expiry date of a certificate: openssl x509 -in certfile -noout -enddate But is there also a shortcut to get only the alternative names? Like when a certificate can be used for example.com as well as www.example.com. In the full dump, it's here: Certificate: Data: X509v3 extensions: X509v3 Subject Alternative Name: DNS:www.example.com, DNS:example.com I'd just like to save me the hassle to parse this output and get the domain names only. Is that possible? Otherwise, what would be best practices to parse this output? What can be assumed, what may change? Could I use a regexp like X509v3 Subject Alternative Name:\s*DNS:(\S+)(?:, DNS:(\S+))*?

• IIS returning plain Forbidden response. No HTTP code

  - by Alex Pineda

  I'm running a ServiceStack application on IIS. My regular services work fine and have not had any problems with permissions. My new project involves providing generated pdfs. I gave IIS_IUSRS read/write permissions to the Temp directory under my app directory. I also allow non SSL connections to this directory. When I browse to the file which ServiceStack is supposed to automatically serve up (eg. http://ryu.com/Temp/201310171723337631.pdf ) I get this: Forbidden Request.HttpMethod: GET Request.PathInfo: Request.QueryString: Request.RawUrl: /ryu/Temp/201310171723337631.pdf App.IsIntegratedPipeline: True App.WebHostPhysicalPath: C:\inetpub\ryu App.WebHostRootFileNames: [global.asax,global.asax.cs,web.config,bin,temp] Now this doesn't look like a ServiceStack error message, more like IIS, but I'm not certain as to how to get to the bottom of this. Authorization settings are Allow All.

• Serving protected files using Nginx's X-Accel-Redirect header

  - by andybak

  I'm trying to serve protected files using this directive in my nginx.conf: location /secure/ { internal; alias /home/ldr/webapps/nginx/app/secure/; } I'm passing in paths in the form: "/myfile.doc" and the file's path would be: /home/ldr/webapps/nginx/app/secure/myfile.doc I just get 404's when I access "http: //myserver/secure/myfile.doc" (space inserted after http to stop ServerFault converting it to a link) I've tried taking the trailing / off the location directive and that makes no difference. Two questions: How do I fix it! How can I debug problems like this myself? How can I get Nginx to report which path it's looking for? error.log shows nothing and access.log just tells me which url is being requested - this is the bit I already know! It's no fun trying things randomly without any feedback. Here's my entire nginx.conf: daemon off; worker_processes 2; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; server { listen 21534; server_name my.server.com; client_max_body_size 5m; location /media/ { alias /home/ldr/webapps/nginx/app/media/; } location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; fastcgi_pass unix:/home/ldr/webapps/nginx/app/myproject/django.sock; fastcgi_pass_header Authorization; fastcgi_hide_header X-Accel-Redirect; fastcgi_hide_header X-Sendfile; fastcgi_intercept_errors off; include fastcgi_params; } location /secure { internal; alias /home/ldr/webapps/nginx/app/secure/; } } } EDIT: I'm trying some of the suggestions here So I've tried: location /secure/ { internal; alias /home/ldr/webapps/nginx/app/; } both with and without the trailing slash on location. I've also tried moving this block before the "location /" directive. The page I linked to has ^~ after 'location' giving: location ^~ /secure/ { ...etc... Not sure what that signifies but it didn't work either!

• Is there a portable version of Spybot Search & Destroy?

  - by NoCatharsis

  I'm trying to make everything portable, as my office IT has cracked down on native app installation. One of my favorites (and a good CYA app in this case) is Spybot. All I can find are directions on how to alter the installation to make it portable. Is there a single download out there that would put the app right onto my USB drive?

• postfix email gateway

  - by k-h

  I am setting up a postfix email gateway. It will not hold any mail but will accept email for my domain and forward it to another internal mailserver and relay mail out from the internal server. One of the main problems is that I am working on a live running system and this will be an upgrade so I am using a test domain which I will change at some point to the real domain. I tried various methods but found the simplest way (that worked) was to use a script to create an aliases file (from ldap entries). There are various problems with this method. The main one being that the entries can't be of the simple form [email protected] because the gateway doesn't know where to send them. They have to be of the form: user@realmailserver.example.com. What I would like doesn't seem hard but I can't get my head around the postfix documentation. There seem to be various ways but none of them seem to work. Most of the examples I have found on the web assume the mail is going to end up on the server. I want a list of users somewhere, preferably of the form: user1, user2, etc rather than [email protected] (I can easily generate this list) and I would like postfix to forward all email to example.com to a particular server: ie realmailserver.example.com. Can anyone suggest clues as to how I might do this?

• Ubuntu in Virtualbox - web server very slow when using local IP address

  - by Lenny Marnham

  I'm using Ubuntu (Lucid Lynx) to learn Ruby On Rails. I'm running Ubuntu in VirtualBox (the host is Windows 7 Ultimate), using bridged networking. When I run my Rails app and point the browser at it using localhost:3000, the app responds immediately and my page is rendered in a second or two. However, if I use 10.0.0.5:3000 (where 10.0.0.5 is my IP address reported using ifconfig), the response from my rails app is incredibly slow - maybe 30 seconds or more for the server to respond and render the page. This happens in both Firefox and Chrome. Also, when I hit the Rails app from the host (to test it in IE), I get the same slooooooow response. Any ideas what might be going on? I've tried it with two different routers, and on two different networks (work and home) with the same result. Cheers all.

• Nginx conditional not evaluating correctly

  - by cjc

  I'm running into a weird problem with nginx and how it evaluates conditionals. Here's the relevant configuration: set $cors FALSE; if ($http_origin ~* (http://example.com|http://dev.example.com:8000|http://dev2.example.com)) { set $cors TRUE; } if ($request_method = 'OPTIONS') { set $cors $cors$request_method; } if ($cors = 'TRUE') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Max-Age' '1728000'; } if ($cors = 'TRUEOPTIONS') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'X-Requested-With, X-Prototype-Version'; add_header 'Access-Control-Max-Age' '1728000'; add_header 'Content-Type' 'text/plain'; } So, the conditional blocks never trigger. When I remove the conditions, I see that the "Access-Test" header and the "Access-Control-Allow-Origin" set correctly, but, as noted, enabling the conditionals causes the headers not to be sent. I'm testing by running: curl -Iv -i --request "OPTIONS" -H "Origin: http://example.com" http://staging.example.com/ Am I missing something obvious? I've tried the "if" with and without quotes, etc. This is nginx 1.2.9.

• Xamp on ubuntu serves php source for root url only

  - by mazaryk

  Hey, Okay, so installed xamp on my ubuntu machine, started it up and everything worked. Apache ran my php app just fine (including requests to the root url "/"). However, after the first reboot since installing, when I request "http://localhost/" apache serves up the index php page as a phtml source file. All other urls (like "http://localhost/login") work as expected. Backgound: The only modification I made to xamp was to setup a vhost for my app. The app uses an .htaccess file where I define some rewrite rules (the app is an MVC framework and all urls are rewritten to a single entry point php file). I'm using Xamp because I need php = 5.3.0. I know apache will serve up the source of a php file when it doesn't know to process php files. But the config does indeed have "AddType application/x-httpd-php .php" and as I said, the app works for all urls except the root "/" (and only since I've rebooted). The .htaccess file does contain a DirectoryIndex directive. xamp 1.3.7a Ubuntu 9.10 Any ideas?

• Rewrite the Base URL with mod_rewrite

  - by rotespferd

  My Domain example.com points to the directory public_html. In the directory public_html/php is my index.php file. Now I want that the URL example.com points to *public_html/php/index.php*. I must do this with mod_rewrite because I have no access to the httpd.conf to do something wth Alias oder DocumentBase. In the directory public_html is my .htacces filewith the following content: RewriteEngine on RewriteCond %{HTTP_HOST} exaple.com$ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /php/index.php [L,QSA] This do half of the job, because when I enter something like example.com/s in my browser it points to *public_html/php/index.php* as I want it to do. But when I just enter example.com it points to *public_html*. What can I do to fix this?

• Trouble running multiple Firefox versions on OS X Lion

  - by politicus

  I am trying to use two versions of Firefox (11 and 13) on OS X Lion. I don't especially want to run two versions at the same time. I want to be able to run the version 11 when I choose the version 11 via the profile manager. The same for the version 13. Every time, I want to launch the version 11, the launcher launches the version 13... When I select the version 11 via the profile manager, Firefox 13 is launched. I created 2 automators apps (FF11.app and FF13.app) to launch Firefox : /Applications/Firefox11.app/Contents/MacOS/firefox-bin -no-remote -P FF11 & /dev/null & /Applications/Firefox13.app/Contents/MacOS/firefox-bin -no-remote -P FF13 & /dev/null & Any help would be greatly appreciated.

  say I have a wordpress site: https://www.foobar.com and I want to have an entry point to a rails app at a certain subdirectory within that same domain: https://www.foobar.com/rails_app I know this is possible if both the wordpress app and the rails app are hosted on the same box, but is this in anyway possible if they are hosted on different boxes? I do not want to use subdomains because I am trying to allow ajax post requests from one to the other and not having to deal with single origin policy stuff.

• Tweaking "Most visited sites" button in Firefox

  - by Mehper C. Palavuzlar

  It is sometimes practical to use "Most Visited" sites which stands on the left hand side of Firefox window. When I click on it, I can see maximum 10 URLs. At that point, I have 2 questions: Is it possible to increase the number of maximum most visited sites (say, 30)? Let's say example.com is one of the most visited domains. In the most visited list, there are other pages from this domain, like example.com/intro, example.com/info, example.com/help etc. So those sub-addresses are also in the list, but I just want to see max 1 (or maybe 2) pages from the same domain in the list. Is it possible to arrange the list this way?

• Should I be using www. when setting up virtual hosts on apache?

  - by MAZUMA

  Does it matter whether or not I include the www. sub-domain when creating new virtual hosts on apache? So is this? /etc/apache2/sites-available/www.example.com better than this? /etc/apache2/sites-available/example.com I would assume I'd need to a2ensite either www.example.com or example.com. Depending on whichever method used? This might be a a fairly basic question But, I have no one else to ask. And, want to do it right.

• Varnish with multiple hosts/subdomains

  - by jerhinesmith

  I'm new to Varnish, and I'm hoping it already does this "out of the box", but I'd like to clarify before I consider using it in production: Here's my setup: I have multiple sites running off of the same machine that vary by subdomain (i.e. user1.example.com, user2.example.com, etc.) Each "site" has a profile picture that has the same name (i.e. user1.example.com/profile.png, user2.example.com/profile.png) Will Varnish recognize these as separate resources and cache them accordingly? Or will I need to change something in the VCL to tell it include the full host url when looking up cache hits?
