• IPCop Packet Mangling

  - by Zenham

  I've found myself in a pickle replacing an old firewall for a client this afternoon. I'm configuring their new IPCop firewall (1.4.21), Zerina OpenVPN addon is installed. What I need to do: There are three network interfaces, currently set up as red (WAN), green (LAN, 192.168.20.0/24) and orange (remote network 10.1.20.0/24). The orange interface is a direct fiber link to another organization. Simple description: Traffic and networks appear to be properly configured at this point, but I have many (150+) specific IPs on the LAN which, when accessing the resources on the 10.1.20.x network, need to be mangled to appear to be coming from the 10.1.20.0/24 network (and return traffic properly delivered). The routing on the far side was configured earlier and should be fine, but I need to redirect any packets coming across destined for those IPs to end up at their proper destination. The addressing is fixed and predictable (ie. 192.168.20.125 - 10.1.20.125). I need to insert whatever rules I have into the IPCop ruleset through /etc/rc.local I know, I'm just not sure about how I should structure this. There's CUSTOMOUTPUT and CUSTOMINPUT targets, both which currently just consist of the single rule redirecting packets to the OVPNOUTPUT/OVPNINPUT targets, so I'm guessing I should insert a rule matching outbound packets destined for the 10.1.20.x network and redirecting to a new target (maybe called TO-ORANGE) and a rule at the top of CUSTOMINPUT which redirects to a FROM-ORANGE target. Under those targets, I would have rules which do the IP matching and mangling. Am I approaching this right? If so, I'm not very familiar with mangle, and would appreciate seeing examples of how to write that source-IP rewrite. If not, how would you suggest doing this? TIA! edit: I notice additionally that the nat table has CUSTOMPREROUTING and CUSTOMPOSTROUTING targets, I guess I could alternatively post the rules in there....

• Wildcard DNS, VirtualHosts on apache2, 404 for unused subdomains

  - by niel

  On an Apache2 server linked to by a DNS that includes a wildcard entry, e.g. *.example.com, subdomains that are not defined as ServerNames in any VirtualHosts point to the first defined VirtualHost, in my example this is 000-default. My Question:How would one get unused subdomains (subdomains not used in any virtualhosts) to return a 404 error to the requesting client? This must preferably show in server logs as a 404 as well. I have looked into the following possibilities: Redirecting any invalid subdomain to the home page or some other page.The problem with this method is, when someone links to your site as this.company.sucks.example.com, the client will see your home page or in my case 000-default if I do not redirect. Thanks, to Mike for pointing this out. (regex for "suck", etc definately not an option) Let the default VirtualHost point to a non-existent directory.Apache does not like this one bit, warning with every reload. Beyond the warning, everything seems fine. This seems like a hack. Does this seem like a problem (however small) to anyone? Point the default VirtualHost to a folder where the index.php is forbidden, thus creating a 403 status code.This is confusing and makes things like the following overly complicated: Say, for example, you use a subdomain per user (a big reason to use wildcard DNS, apparently), and users have the ability to view each others profiles at username.example.com. This solution is confusing to the user and completely not what I want to do. My ideal sollution will let the user know there is nothing to view at the url he entered. Preferably with a 404 and an error log entry for the address entered (not some other address). Any help would be greatly appreciated!

• How come the ls command prints in multiple columns on tty but only one column everywhere else?

  - by David Lou

  Even after using Unix-like OSes for a couple years, this behaviour still baffles me. When I use the ls command in a directory that has lots of files, the output is usually nicely formatted into multiple columns. Here's an example: $ ls a.txt C.txt f.txt H.txt k.txt M.txt p.txt R.txt u.txt W.txt z.txt A.txt d.txt F.txt i.txt K.txt n.txt P.txt s.txt U.txt x.txt Z.txt b.txt D.txt g.txt I.txt l.txt N.txt q.txt S.txt v.txt X.txt B.txt e.txt G.txt j.txt L.txt o.txt Q.txt t.txt V.txt y.txt c.txt E.txt h.txt J.txt m.txt O.txt r.txt T.txt w.txt Y.txt However, if I try to redirect the output to a file, or pipe it to another command, only a single column appears in the output. Using the same example directory as above, here's what I get when I pipe ls to wc: $ ls | wc 52 52 312 In other words, wc thinks there are 52 lines, even though the output to the terminal has only 5. I haven't observed this behaviour in any other command. Would you like to explain this to me?

• Apache2 - mod_rewrite : RequestHeader and environment variables

  - by Guillaume

  I try to get the value of the request parameter "authorization" and to store it in the header "Authorization" of the request. The first rewrite rule works fine. In the second rewrite rule the value of $2 does not seem to be stored in the environement variable. As a consequence the request header "Authorization" is empty. Any idea ? Thanks. <VirtualHost *:8010> RewriteLog "/var/apache2/logs/rewrite.log" RewriteLogLevel 9 RewriteEngine On RewriteRule ^/(.*)&authorization=@(.*)@(.*) http://<ip>:<port>/$1&authorization=@$2@$3 [L,P] RewriteRule ^/(.*)&authorization=@(.*)@(.*) - [E=AUTHORIZATION:$2,NE] RequestHeader add "Authorization" "%{AUTHORIZATION}e" </VirtualHost> I need to handle several cases because sometimes parameters are in the path and sometines they are in the query. Depending on the user. This last case fails. The header value for AUTHORIZATION looks empty. # if the query string includes the authorization parameter RewriteCond %{QUERY_STRING} ^(.*)authorization=@(.*)@(.*)$ # keep the value of the parameter in the AUTHORIZATION variable and redirect RewriteRule ^/(.*) http://<ip>:<port>/ [E=AUTHORIZATION:%2,NE,L,P] # add the value of AUTHORIZATION in the header RequestHeader add "Authorization" "%{AUTHORIZATION}e"

• Two hosting providers running simultaneously... possible / not possible? good practice / unnecessary?

  - by user29600

  For the sake of their reputation, I won't mention the names. But I'll just use: Business I worked for previously - ABC Web Dev Hosting company they used - XYZ Hosting I recently found out that XYZ Hosting had some sort of incident where they ended up losing a lot of their client's data - including ABC Web Dev's. ABC Web Dev was able to recover some of their customer's websites, after pulling them from their local development computers and putting them up on another hosting provider. They ended up losing a lot of clients because of it and their reputation ruined. I'm starting my own web dev company and I don't want to run into this same issue. I'm planning on using Rackspace but, although they are a great company, according to wikipedia they still have had downtime in their past. I thought it might be a good idea to try to run two providers at once, to ensure that if anything happened in one the websites would still be live because of the other. I know the websites would have to be pulling from one server at all times, but if there's a way to redirect requests to the second server if the first one is down that would solve my issue. As a note, we will have a staging environment setup locally which will allow for quick recovery if a provider did have any issues, however I'd like to avoid any downtime at all if possible. So my questions are: Has anyone tried running two providers simultaneously? Would this be considered good practice or am I going too far? Is there really any way to run two simultaneously where one server acts as a backup?

• Monitor Exchange Email Address and run scripts

  - by WernerCD

  Okay... Not sure how "out there" this thought is... Right now to send a pager message (aka text message), a user logs into our AS400... logs into the program... enters user name and message and hit's F10 to send. With a little looking, it seems that you can run remote commands to the AS400 via FTP. So I'm working on building a script (batch or otherwise) that, given two parameters (user, message), will FTP into the AS400 and run a remote command: c:\>ftp server user: admin password: ***** ftp> quote rcmd SNDPGRMSG TOPGR(JDOE) MSG('This is a Test') ftp> quit So... what I want to do is setup an email account on our Exchange server Monitor the account for incoming mail upon receipt of incoming mail, parse it... say for example subject is defined as "Recipient" and email text is defined as "Pager message" run a batch that uses the above mentioned TOPGR and MSG as parameters... via FTP to the AS400 mark email as "read" The main thing I'm not sure about is monitoring an exchange account and running a script on incoming emails. I'm sure what I want to do is possible... but where would I start? EDIT: Clarification The main reasons for using this four part system are logging (messages sent via this are logged and reported by the AS400 program) and the existing scheduler for redirecting pages (For example, the weekly on-call person = TOPGR(oncall) gets updated by the AS400 program). I'm also trying to remove duplicate work. If I can get this setup working, I can redirect pages from OTHER systems into this one. I then don't have to update 2, soon to be 3, systems with current phone numbers, carriers, on-call schedules, etc. System #2 and #3 can just "email" [email protected].

• E-mail hosting provider that can set up aliases with wildcards

  - by Richard Downer

  I am looking for an e-mail hosting provider that allow e-mail aliases containing wildcards. In more detail: I own my own domain. I want an e-mail hosting provider to manager e-mail for my domain. Now, to help deal with spam, I often give different e-mail addresses to different organisations. These e-mail addresses always start with the same prefix, but then differ. So, for example, I might give out these e-mail addresses: [email protected] [email protected] [email protected] I want to be able to go to the e-mail provider's control panel and set up an e-mail alias like this: [email protected] -- bounce/discard (because this address has been sold to spammers) joe-*@sample.com -- redirect to [email protected] What's I don't want to do is either have to set up every single e-mail address individually (because I make them up whenever I need them), nor do I want to have a general catch-all for any unrecognised address in my domain (because I don't want to be carpet-bombed with spam when a spammer runs a dictionary attack against my domain name.) Although this seems like a useful feature to have, it seems to be a little-known feature and I've not seen anybody advertise this feature. My current hosting provider offer this but I want to move away from them, so I need another provider that will continue to work with all the e-mail addresses I've been using for years. Alternatively, I could use mail server software that runs on Windows - I have seen some commercial packages offering this feature but they cost more than I can afford - are there any suggestions for low-cost software packages?

• Domain with www pointing yo another site

  - by ntechi

  Recently I started Multi Sites on my VPS which is having Centos 64 bit. Currently I am having two sites live and each is working fine, Now the problem is in the URL I have the following sites: http://mbas.co.in http://u-k.in mbas was the very first site on my VPS Now in URL if I type http://mbas.co.in or http://www.mbas.co.in both redirect to my mbas website But for the second website, If in URL I type http://u-k.in then it redirects to the u-k website correctly but if I type http://www.u-k.in then it redirects me to mbas website. You can try that I have configured my DNS in this way, see the image http://i55.tinypic.com/14vlpxl.jpg And my Multi Site code is this <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /var/www/html/www.mbas.co.in ServerName mbas.co.in ErrorLog logs/mbas.co.in-error_log CustomLog logs/mbas.co.in-access_log common </VirtualHost> <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /var/www/html/u-k.in ServerName u-k.in ErrorLog logs/u-k-error_log CustomLog logs/u-k-access_log common </VirtualHost>

• How to completely disable laptop sound?

  - by Alvaro Rodriguez

  I have a HP Pavillion DV7 laptop with win 8 pro. The laptop has an unidentified problem with sound drivers or hardware that sometimes causes volume to constantly jiggle up and down. This is very annoying because of these consequences: Renders mute unusable - as the volume changes the sound unmutes automatically Causes an annoying win 8 "surface UI" notification to appear constantly in the upper left corner, which is distracting enough by itself, but more importantly Renders the whole "surface UI" unusable, because it loses focus whenever the sound changing notification appears When the jiggling happens, the laptop also loses the ability to redirect sound to earphones - sound comes out of the speakers even if earphones are connected. To solve these issues I want to completely disable sound in the laptop (I've tried reinstalling drivers several times to no end). I have tried disabling all sound related drivers and devices in the Device Manager but Windows re-enables those automatically whenever I restart the laptop. The BIOS doesn't have any settings to disable sound hardware either. Please don't suggest having the laptop sound serviced or fixed. It's not worth the expense. I just want to remove sound support so I can use it normally. It is very unusable as it is now.

• Active Directory Domain Services - Network Name Cannot be Found

  - by Arief

  I have really weird problem that I could not explain. I am trying to redirect all users home folder to the new server. I have copied all the files including the permissions to the new server. All I need to do is to update the user profile for home folder by changing the server name. However, I got this message when I enter the new server name: My server that serving as AD can resolve the name by ping and nslookup of the server name. The only thing that I don't understand why the MMC cannot resolve the name. I did change with the IP Address and I still get the same error message. Thank you so much for your help. UPDATE: I know what seems to be a problem, but I don't know how to fix it. The new server that will serve all Home folder is actually sitting in the cloud with different IP Address as the Domain Controller. The Domain Controller is sitting locally in the office with 10.0.0.0/24 IP Addresses. The new server that is sitting in on Data Centre is on 172.10.10.10/24 IP Addresses. The static route has been set up on both end, and the DNS as well. I believe this is the issue. Does anyone how to overcome this situation? Thank you.

• Apache mod_rewrite weird behavior in Internet Explorer

  - by morrty

  I'm attempting to setup redirection for a couple of root domains. Firstly, here is the code in my httpd-vhosts.conf file: <VirtualHost *:80> ServerAdmin ****@example.com ServerName example.com ServerAlias example2.com RewriteEngine On RewriteCond %{HTTP_HOST} !^192\.168\.0\.1$ # This is our WAN IP RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteCond %{HTTP_HOST} !^$ RewriteRule ^/?(.*) http://www.%{HTTP_HOST}/$1 [L,R,NE] </VirtualHost> What this does is redirect the root domain of example.com or example2.com or any host other than www to www.example(2).com The part I'm having a problem with is the RewriteRule itself. the $1 is supposed to match the pattern of the RewriteRule and add it in the substitution. For example: "http://example.com/test.html" should rewrite to "http://www.example.com/test.html" It works in all modern browsers like it's supposed to except for IE8 or IE9 (I didn't test other IE versions). In IE, this works: "http://example.com" to "http://www.example.com" In IE, this does not work: "http://example.com/test.html" to "http://www.example.com/test.html" Does anyone have an explanation for this behavior? I hope I've explained it well enough. Thank you.

• Apache > 2.2.22 rewrite rule not working?

  - by EBAH

  since yesterday I'm trying to figure out how to fix the following: running phpipam (http://www.phpipam.net/) with WAMP (Windows environment). The problem I am facing is related with RewriteRule functionality, so forget phpipam for a moment and concentrate on few lines of code. Here is the directory structure of my test website that emulate the first steps phpipam does (you can download http://goo.gl/ksvuGc): C:\wamp\www\rewrite-tst\ C:\wamp\www\rewrite-tst\.htaccess C:\wamp\www\rewrite-tst\index.php C:\wamp\www\rewrite-tst\install C:\wamp\www\rewrite-tst\install\index.php It seems that the following rewrite rule in .htaccess doesn't work: C:\wamp\www\rewrite-tst\.htaccess # install RewriteRule ^install$ install/ [R] RewriteRule ^install/$ index.php?page=install When opening C:\wamp\www\rewrite-tst\index.php the first step check the URL for "install" argument. Since the URL is: http://localhost/rewrite-tst no arguments are supplied and the browser is redirected to: header("Location: /rewrite-tst/install/") At this point the browser opens the page: C:\wamp\www\rewrite-tst\install\index.php >> http://localhost/rewrite-tst/install Apache, thanks to C:\wamp\www\rewrite-tst.htaccess should intercept this URL and redirect to: http://localhost/rewrite-tst/index.php?page=install Here are my tries: Win Apache 2.2.22: works Win Apache 2.4.4: KO Win Apache 2.4.6: KO In the attached zip file you can also find two traces from apache RewriteLog which I can't understand very well. Why Apache 2.4 doesn't work on Windows? Is it possible that there's a bug on Windows version of Apache (2.4.4 and 2.4.6) or am I wrong someway? Thanks for your help!!! Evan -- UPDATE 12 oct 2013 Now I'm really confused! Working on Linux, Kubuntu 13.04. Linux Apache 2.2.22: works Linux Apache 2.4.6: KO I guess there's something wrong in my rules at this point, or some change happened from Apache 2.2 to 2.4 ...

• IIS 7 rewriting subdomain to point at a specific port

  - by Tommy Jakobsen

  Having installed Team Foundation Server 2010 on Windows Server 2008, I need an easy URL for our developers to access their repositories. The default URL for the TFS repositories is http://localhost:8080/tfs Now I want the subdomain domain tfs.server.domain.com to point at http://localhost:8080/tfs. And when you access tfs.server.domain.com/repos_name it should redirect to http://localhost:8080/tfs/repos_name. How can I do this in IIS7? I already tried using the following rule, but it does not work. I get a 404. <rewrite> <globalRules> <rule name="TFS" stopProcessing="true"> <match url="^(?:tfs/)?(.*)" /> <conditions> <add input="{HTTP_HOST}" pattern="^tfs.server.domain.com$" /> </conditions> <action type="Rewrite" url="http://localhost:8080/tfs/{R:1}" /> </rule> </globalRules> </rewrite> EDIT I actually got this working by adding a binding for the site on port 80 with host name tfs.server.domain.com. But using tfs.server.domain.com, I can't authenticate using Windows Authentication. Is there something that I need to configure for Windows Authentication? You can see a trace here: http://pastebin.com/k0QrnL0m

• How to setup equivalent USVIDEO.ORG DNS-Proxy on Linux

  - by Gary

  I have a VPS in the USA running Ubuntu. I want to setup something similar to http://www.usvideo.org Basically, USVIDEO is a DNS service that allows Canadians to access American content like Hulu, Netflix, NBC, and etc (restricted by geographical IP). Here is how I think USVideo does it: Clients (PS3, XBOX, PC) specifies the DNS server(s) as specified on USVIDEO.org's website. If the DNS request is a video/audio site such as Netflix or Pandora, forward the request to a proxy. Otherwise, for all other requests, forward it to a different DNS server. If the specific video/audio URL is requested, return the address of the proxy server, which in turn relays traffic to the destination video/audio domain via the U.S. gateway so that it appears that the access is coming from a U.S. IP address. Once the DNS request has passed the U.S. IP address check, their proxy server steps out of the loop and lets the video streaming site contact you directly to start the video stream. This trick relies on the way that the video streaming sites check the country of your IP address once up front, but don't actually check the country of the destination IP address while the video is streaming. What is elegant about this solution is that a VPN Tunnel is not required to bypass geographical IP checks from certain websites. All that is required on the client side is to specify the DNS server (the VPS). If a certain site is geographically locked, just forward the traffic to a proxy, and that's it. These sites can be specified in the DNS entries, or perhaps in the proxy service to redirect the DNS request to its own proxy. I believe what I need to setup something similar is Squid Proxy, IPTables, and DNS. What I need help is how to exactly approach this? Would Squid Proxy be setup as a transparent proxy?

• Is one server on a vlan unnecessary?

  - by moomoochoo

  DETAILS I've been researching web hosting solutions in Japan. Based on this question one of the services available seems to be a VLAN. I've read about the advantages of such a system for a large organization, but there doesn't seem to be much information regarding smaller setups. I take that to mean that for one server it is likely to be unnecessary? My concern is that I don't know how many other servers are on the WAN, so regardless of how many servers I use a VLAN might still be a good idea. SERVER INFO One dedicated server would be used. It would not be virtualized. My Research so far Based on comments here, a VLAN would be useful for mitigating these problems. A user on another server could, either mistakenly or maliciously, assign one of your IP addresses to their server, resulting in a "duplicate IP" situation that would cause connectivity issues. A user on another server could poison the arp cache and potentially redirect traffic to snoop on communication intended to/from your server. (later in the discussion this point was said to be unrealistic.) QUESTION Is it worthwhile getting a vlan for one dedicated server? Will it be easier/the same/ harder to manage?

• IIS 7.5 Siteminder Does not protect ASP.net MVC requests

  - by HariM

  We are trying to use ASP.Net MVC with Siteminder for Single Sign on. This is on Windows Server 2008 R2 with IIS 7.5. Siteminder Agent version 6QMR6. Problem : Siteminder protects physical files that are exist. And it is not protecting the folder when we try to access a non existed file. It must redirect to login page even if the file doesn't exist when the user is accessing a protected folder. How to configure in IIS 7.5 that Do not verify a file exist, before authentication by siteminder. SiteMinderWebAgent is a Handler(WildCard Script Map) we created using the ISAPI6WebAgent.dll How to Protect ASP.Net MVC Request with Siteminder? (Added this as My previous question did not solve the problem). MVC Request shows up in IIS Log but not in Siteminder log. Update : Microsoft Support says currently IIS7.5, even in earlier versions doesnt support wildcard mappings on any two Isapi Handlers with * wild card. Currently in my case Siteminder has * wildcard and asp.net mvc (handler is aspnet_isapi) has * wildcard to handle the reqeusts. Ordered priority doesnt work in the wild card mappings case with Just *. Did not convinced with the answer but will wait till tomorrow for them to get back.

• Cannot connect on TFS 2012 server through SSL with invalid certificate

  - by DaveWut

  I saw the problem on some forums and even here, but not as specific as mine. So here's the thing, So I've configured a TFS 2012 server, on one of my personnel server at home, and now, I'm trying to make it available through the internet, with the help of apache2 on a different UNIX based, physical server. The thing is working perfectly, I don't have any problem accessing the address https://tfs.something.com/tfs through my browser. The address can be pinged and I do have access to the TFS control panel through it. How does it work? Well, with apache2 you can set a virtual host and set up the ProxyPass and ProxyPassReserver setting, so the traffic can externally comes from a secure SSL connection, through a specified domain or sub-domain, but it can be locally redirect on a clear http session on a different port. This is my current setup. As I already said, I can access the web interface, but when I'm trying to connect with Visual Studio 2012, it can't be done. Here's the error I receive: http://i.imgur.com/TLQIn.png The technical information tells me: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. My SSL certificate is invalid and was automatically generated on my UNIX server. Even if I try to add it in the Trusted Root Certification Authorities either on my TFS server or on my local workstation, it doesn't work. I still receive the same error. Is there's a way to completely ignore certificate validation? If not, what's have I done? I mean, I've added the certificate in the trusted root certificates, it should works as mentioned on some forums... If you need more information, please ask me, I'll be pleased to provide you more.

• iptables configuration to work with apache2 mod_proxy

  - by swdalex

  Hello! I have iptables config like this: iptables -F INPUT iptables -F OUTPUT iptables -F FORWARD iptables -P INPUT DROP iptables -P OUTPUT DROP iptables -P FORWARD DROP iptables -A INPUT -p tcp --dport 22 -j ACCEPT iptables -A OUTPUT -p tcp --sport 22 -j ACCEPT iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -A OUTPUT -p tcp --sport 80 -j ACCEPT iptables -A INPUT -p tcp --dport 443 -j ACCEPT iptables -A OUTPUT -p tcp --sport 443 -j ACCEPT Also, I have apache virtual host: <VirtualHost *:80> ServerName wiki.myite.com <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8901/ ProxyPassReverse / http://localhost:8901/ <Location /> Order allow,deny Allow from all </Location> </VirtualHost> My primary domain www.mysite.com is working well with this configuration (I don't use proxy redirect on it). But my virtual host wiki.mysite.com is not responding. Please, help me to setup iptables config to allow wiki.mysite.com working too. I think, I need to setup iptables FORWARDING options, but I don't know how. update: I have 1 server with 1 IP. On server I have apache2.2 on 80 port. Also I have tomcat6 on 8901 port. In apache I setup to forwarding domain wiki.mysite.com to tomcat (mysite.com:8901). I want to secure my server by disabling all ports, except 80, 22 and 443.

• Configure J2EE Agent with OpenAM behind Reverse Proxy

  - by Troy

  I have a reverse proxy with two SSL enabled NamedVirtualHosts on different ports. Both containers on each internal host is GF 2.1.1. Proxy configuration as follows: Proxy URL -> Internal URL https://apps.mydomain.com -> http://apps.internal.com https://secure.otherdomain.com:8080/ -> http://secure.internal.com I initially tried configuring the J2EE agent in OpenAM and the web app container to use the internal URLs (I appended /openam and /agentapp respectively). However, I received the following errors when trying to access a secured application such as https://apps.mydomain.com/webapp. java.lang.RuntimeException: Failed to load configuration: ApplicationSSOTokenProvider.getApplicationSSOToken(): Unable to get Application SSO Token A second attempt gives the following error: java.lang.NoClassDefFoundError: Could not initialize class com.sun.identity.agents.filter.AmFilterManager Along with these in the agent debug.out: ERROR: Failed to obtain auth service url from server: null://null:null ... SiteMonitor: Site URL http://secure.internal.com/openam/namingservice is not available. If I specify the server and agent urls using the proxy urls, then the agent appears to be working and I am redirected to the OpenAM login page. However, the goto in the URL is http://apps.mydomain.com/webapp instead of https://apps.mydomain.com/webapp (missing https). So after authentication, the redirect fails. Now I could possibly get by with mod_rewrite, but it feels hackish and I really want to know what's going on. Any ideas?

• MySQL -- enable connection to remote server via local /tmp/mysql.sock

  - by Kevin

  Hey all, I run a shared hosting provider and we're looking to move to a High Availability (replicated across multiple datacenters) setup for our hosting. We have created a replicated MySQL setup with failover that works wonderfully, and we'd like to move all of our clients' databases to it. The only trouble is that we have many many customers, all of whom have configured their Wordpress, Drupal, etc. installations to connect to MySQL via a local socket, not to the address of the remove server. I would hate to have to go through manually and change the connection statement in all of our clients' sites. What I'd ideally love to see is a program that listens on /tmp/mysql.sock and forwards connections there to the remote server I specify. I've seen SQL Relay, but it seems to require that I hardcode all of the database names and usernames and passwords into its configuration file. This is not going to work for me because our users add new databases dynamically all of the time, and I'd rather not have to write code to updated SQLRelay's config file every time. Does anyone have an idea on how to do this? Alternatively, I'd accept idea on how to handle this at the PHP level. (i.e. redirect any attempted calls to mysql_connect() to use that hostname rather than localhost) Thanks, Kevin

• How to install a private user script in Chrome 21+?

  - by Mathias Bynens

  In Chrome 20 and older versions, you could simply open any .user.js file in Chrome and it would prompt you to install the user script. However, in Chrome 21 and up, it downloads the file instead, and displays a warning at the top saying “Extensions, apps, and user scripts can only be added from the Chrome Web Store”. The “Learn More” link points to http://support.google.com/chrome_webstore/bin/answer.py?hl=en&answer=2664769, but that page doesn’t say anything about user scripts, only about extensions in .crx format, apps, and themes. This part sounded interesting: Enterprise Administrators: You can specify URLs that are allowed to install extensions, apps, and themes directly through the ExtensionInstallSources policy. So, I ran the following commands, then restarted Chrome and Chrome Canary: defaults write com.google.Chrome ExtensionInstallSources -array "https://gist.github.com/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://gist.github.com/*" Sadly, these settings only seem to affect extensions, apps, and themes (as it says in the text), not user scripts. (I’ve filed a bug asking to make this setting affect user scripts as well.) Any ideas on how to install a private user script (that I don’t want to add to the Chrome Web Store) in Chrome 21+? Update: The problem was that gist.github.com’s raw URLs redirect to a different domain. So, use these commands instead: # Allow installing user scripts via GitHub or Userscripts.org defaults write com.google.Chrome ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" This works!

• Win7 Domain User Profile- Desktop Icon management best practices request

  - by Doltknuckle

  Here's the situation: We have a large (5,000+ user) organization that is currently using folder redirection to manage the windows desktop icons. This folder is redirected to a network share where we can centrally manage the different sites and such. When a user tries to use a computer when the network is not available, they are unable to use any shortcuts in the Public folder. We only redirect the C:\Users\%username%\Desktop folder. Does anyone have any suggestions of how to go about managing desktop icons? We still want a central location to manage these items, but find a way to keep the system working when the network is unavailable. As a point of clarification, the network rarely goes down. We do have instances where a few computers do not have a network connection. Usually, something is simply unplugged. Since we have multiple sites, the line from a branch to the central office has gone down a few times. This is more of an attempt to maintain a positive end user experience when disconnected from the network.

• Nginx - Enable PHP for all hosts

  - by F21

  I am currently testing out nginx and have set up some virtual hosts by putting configurations for each virtual host in its own file in a folder called sites-enabled. I then ask nginx to load all those config files using: include C:/nginx/sites-enabled/*.conf; This is my current config: http { server_names_hash_bucket_size 64; include mime.types; include C:/nginx/sites-enabled/*.conf; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; root C:/www-root; #charset koi8-r; #access_log logs/host.access.log main; location / { index index.html index.htm index.php; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server{ server_name localhost; } } And this is one of the configs for a virtual host: server { server_name testsubdomain.testdomain.com root C:/www-root/testsubdomain.testdomain.com; } The problem is that for testsubdomain.testdomain.com, I cannot get php scripts to run unless I have defined a location block with fastcgi parameters for it. What I would like to do is to be able to enable PHP for all hosted sites on this server (without having to add a PHP location block with fastcgi parameters) for maintainability. This is so that if I need to change any fastcgi values for PHP, I can just change it in 1 location. Is this something that's possible for nginx? If so, how can this be done?
