• Connecting to network device behind NAT from local LAN using the external port and IP

  - by lumbric

  I noticed at several different LANs connected to the Internet through a NAT the following phenomena. There is a server in the LAN and there is a port forwarding to reach this server also from outside the LAN through the NAT. E.g. consider a LAN with the address 192.168.0.* and a SSH server at 192.168.0.2 with port 22 and a forwarding from port 2222 at the NAT 192.168.0.1 to 192.168.0.2:22. If the NAT's external IP is 44.33.22.11, one can connect to the SSH server through 44.33.22.11:2222. Surprisingly this works only from outside the LAN. If one tries to connect to 44.33.22.11:2222 from behind the NAT, there is no answer. Of course one could simply use 192.168.0.2:22, but often it is simpler to use the external IP. The typical use case for me is the configuration on a laptop computer. Usually the user uses any arbitrary Internet connection to connect to his home or office server, but sometimes he will use also the LAN to connect to it and it would be annoying to have to different configurations or bookmarks. Why does it fail to connect from inside the LAN? Is there any good work around?

• How would I change the DocumenRoot on the version of Apache that came pre-installed on my Mac OS X s

  - by racl101

  OK, so I want to take advantage of the Apache server that comes installed on my Mac OS X system (which means, I would like not to have to install my own version of Apache since I might as well tryto use what comes bundled), and as such, I went to change some settings in the configuration file: /etc/apache2/httpd.conf Namely, I changed the these two lines: DocumentRoot "/Users/myusername/Sites" <Directory "/Users/myusername/Sites"> So that they initially pointed to a folder in my Dropbox folder (so I could have my docs sync to my Dropbox): DocumentRoot "/Users/myusername/Dropbox/public_html" <Directory "/Users/myusername/Dropbox/public_html"> That didn't work. So then I figured, ok maybe it was too much to ask to make folder in my Dropbox be my document root. So then I thought, what if I make the Document root another folder of my choosing like so: DocumentRoot "/Users/myusername/dev-sites/public_html" <Directory "/Users/myusername/dev-sites/public_html"> and that didn't work either. After looking within the httpd.conf file for clues it seems that only two directories appear to work as Document root paths for the Apache that comes bundled with Mac OS X: /Users/myusername/Sites (or ~/Sites) and /Library/WebServer/Documents/ But trying to use any other directories didn't seem to work. I would get 403 errors on my browser. I was wondering if there was some other settings to change on the httpd.conf file or any permissions to set to make this work. Any help would be appreciated and many thanks in advance.

• PFSence VPN Routing

  - by SvrGuy

  We use PFSense firewalls at three installations with the following LAN networks: 1.) Datacenter #1: 10.0.0.0/16 2.) Datacenter #2: 10.1.0.0/16 3.) HQ: 10.2.0.0/16 All of these locations are linked via an IPSEC tunnel that works properly. Hosts in any of the above networks can communicate with hosts in any other of the above networks. Now, for our laptops etc. we established a road warrior network 10.3.0.0/16 and have implemented OpenVPN to link the laptops etc. to Datacenter #1. This works great too, so our laptops can connect and communicate with any host in Datacenter #1 (anything on 10.0.0.0/16) The problem is the laptops can't communicate with any hosts that Datacenter #1 can reach by its IPSEC tunnel to Datacenter #2 (and/or the HQ for that matter). Does anyone know what to do configuration wise on the PFSense box in Datacenter #1 to configure to route packets received on the OpenVPN tunnel to Datacenter #2 over the IPSEC tunnel? It could be a setting on the OpenVPN or some sort of static route or some such. Any ideas?

• Removing HttpModule for specific path in ASP.NET / IIS 7 application?

  - by soccerdad

  Most succinctly, my question is whether an ASP.NET 4.0 app running under IIS 7 integrated mode should be able to honor this portion of my Web.config file: <location path="auth/windows"> <system.webServer> <modules> <remove name="FormsAuthentication"/> </modules> </system.webServer> </location> I'm experimenting with mixed mode authentication (Windows and Forms). Using IIS Manager, I've disabled Anonymous authentication to auth/windows/winauth.aspx, which is within the location path above. I have Failed Request Tracing set up to trace various HTTP status codes, including 302s. When I request the winauth.aspx page, a 302 HTTP status code is returned. If I look at the request trace, I can see that a 401 (unauthorized) was originally generated by the AnonymousAuthenticationModule. However, the FormsAuthenticationModule converts that to a 302, which is what the browser sees. So it seems as though my attempt to remove that module from the pipeline for pages in that path isn't working. But I'm not seeing any complaints anywhere (event viewer, yellow pages of death, etc.) that would indicate it's an invalid configuration. I want the 401 returned to the browser, which presumably would include an appropriate WWW-Authenticate header. A few other points: a) I do have <authentication mode="Forms"> in my Web.config, and that is what the 302 redirects to; b) I got the "name" of the module I'm trying to remove from the inetserv\config\applicationHost.config file; c) I have this element in my Web.config file: <modules runAllManagedModulesForAllRequests="false">; d) I tried a <location> element for the path in which I set the authentication mode to "None", but that gave a yellow exception page that the property can't be set below the application level. Anyone had any luck removing modules in this fashion?

• VirtualName-based local development host behind corporate proxy (MAMP)

  - by geerlingguy

  I am behind a corporate proxy server/firewall, and this firewall seems to not be too happy with my idea of local development. On my home computer (Mac/Leopard), I have MAMP running, with a rule in /etc/hosts that directs dev.example.com to 127.0.0.1, and I have a virtualhost set up in the httpd.conf file which works great for me. However, at work, I set up the exact same configuration, but am not able to access dev.example.com, likely due to some address/DNS translation going on via the proxy server. Here are the relevant details from Terminal: $ ping dev.example.com PING dev.example.com (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.025 ms $ host dev.example.com Host dev.example.com not found: 3(NXDOMAIN) I've tried adding dev.example.com to the list of bypass addresses in System Preferences (the 'Bypass proxy settings for these Hosts & Domains' list), but that had no effect. Is there any way I can develop locally using name-based hosts at work? I can access localhost, but can't get to the dev.example.com (or any other custom virtualhosts) here at work, which complicates other matters related to the sites on which I'm working...

• SBS 2008 - DNS Forwarders timing out.

  - by Moif Murphy

  Hello, We have an SBS 2008 server that keeps losing connection to the internet approx 2-3 times a day. It's a simple setup, BT Business Broadband ADSL to a Wireless Zyxel router to the server. Clients connect via WiFi from their laptops. Plugging ethernet in makes no difference, only a reboot of the router seems to bring everything back again. I'm looking at the forwarders on the DNS properties page and they're timing out when trying to resolve the IPs. Currently there are two IPs in there, 194.72.9.34 which has timed out and 194.72.9.38 which has finally resolved to ns8.bt.net We've been in there and replaced all media, installed a PCI NIC, have changed the router three times. There are no errors in the DNS event logs pertaining to what's going on. We've also been on to BT who are adamant that it's not their end. Could someone shed some light on what could be going on or where else to look in the configuration of the server? Thank you.

• server_name seems to be ignored in nginx

  - by user46171

  I have two domains set up in nginx.conf. Both are using SSL with their own certificates, and proxy to Apache. However the second domain is completely ignored, and nginx always resolves to the first domain. I can't see what in the issue is with this configuration, having set the server_name in each case correctly (as far as I can see): http { include mime.types; default_type application/octet-stream; keepalive_timeout 65; upstream site { # real IP addresses masked server xx.xxx.x.xxx; server xx.xxx.x.xxx; } server { # this domain always works listen 443; server_name *.first-site.com; ssl on; ssl_certificate /var/ssl/first-site.crt; ssl_certificate_key /var/ssl/first-site.key; location / { access_log off; proxy_connect_timeout 15; proxy_next_upstream error; proxy_pass http://site; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Protocol https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_redirect off; } } server { # this domain is ignored, always resolves to first-site.com listen 443; server_name *.second-site.com; ssl on; ssl_certificate /var/ssl/second-site.crt; ssl_certificate_key /var/ssl/second-site.key; location / { access_log off; proxy_connect_timeout 15; proxy_next_upstream error; proxy_pass http://site; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Protocol https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_redirect off; } } }

• How to set up a server without a hosting control panel

  - by A4J

  I have always used a control panel on my dedicated servers - from cPanel to Plesk to Virtualmin, and I am now considering ditching a CP altogether and manually editing config files. My requirements are fairly simple, I will host multiple sites on the server; some Apache with PHP & Mysql and some Passenger with Rails & Postgres. All will require email smtp/pop. FTP/Stats will not be required. Could someone please give me a quick run-down of what I would need to do - in terms of installing software and configuration? My server will come with a base install of CentOS 6.4 minimal. My thoughts so far: Install/update latest versions of MySQL & Postgres (are they 'safe' out of the box? Or do I need to do anything else like set up root passwords etc?) Install Apache & PHP (again, are the base installs good to go or do they require security tweaks?) Set up nameservers/hostnames/reverse DNS etc (Any guides on how to do this please?) Install Rubygems Install and configure Dovecot and Postfix (any tips on doing this? Or links to how-tos that cover it please?) Set up each website - any links to guides on how to do this? Install/configure firewall (or is the default install good to go?) Any other tips or advice would be greatly appreciated, as would links to guides or how-tos.

• Problem with connecting two different networks

  - by tanascius

  I have two networks: 192.168.13.0/24 (blue) and 192.168.15.0/24 (green). Computer A is connected to the 13-net, only. Computer B has two interfaces, one in each network. There is third computer that acts like a router and connects the 13-net to the 15-net (only in this direction). Now, I'd like to ping 192.168.15.100 from computer A to B. Unfortunately there is never a reply. But when I use a hub instead of a switch it works. In my opinion the ping packet travels through the switch to the router (which is the default route/gateway for A). The router sends the packet back to the switch to B. Probably B receives it on its 15-net interface but answers with it's 15th interface? Is this possible? The problem is, that B may have only a gateway 192.168.13.50 - but I am not really sure of it (B is a embedded system with limited configuration possibilities). Can anyone explain what happens here? Thank you!

• trouble executing php scripts with nginx

  - by lovesh

  My nginx config looks like this server { listen 80; server_name localhost; location / { root /var/www; index index.php index.html; autoindex on; } location /folder1 { root /var/www/folder1; index index.php index.html index.htm; try_files $uri $uri/ index.php?$query_string; } location /folder2 { root /var/www/folder2; index index.php index.html index.htm; try_files $uri $uri/ index.php?$query_string; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; } } The problem with the above setup is that i am not able to execute php files. Now as per my understanding of nginx config rules, when i am in my webroot(/) which is /var/www the value of $document_root becomes /var/www so when i request for localhost/hi.php the fastcgi_param SCRIPT_FILENAME becomes /var/www/hi.php and that is the actual path of the php script. Similarly when i request for localhost/folder1/hi.php the $document_root becomes /var/www/folder1 because this is specified as the root in folder1's location block so again the fastcgi_param SCRIPT_FILENAME becomes /var/www/folder1/hi.php. But because the above configuration does not work so there is something wrong with my understanding. Please help?

• using nginx with proxy_pass on a subdomain

  a have a rails app that should listen on the subdomain redmine.example.com (using proxy_pass). all other requests for *.example.com should just redirect to a normal index.html.

• Disable all the idiot-checking in Mac OS X

  - by Fake Name

  I am a Windows/Linux user, who is learning Mac OS X out of interest in doing dev-work for the iPad which I recently purchased. However, OS X is driving me nuts by trying to protect all it's system files, hiding all of the important OS components I want to tweak, and generally making it impossible to do any modification to the OS in general to make it more usable. Therefore, is there a way to turn off all the idiot-checking in Finder? On XP, I can disable "Hide Protected Operating system files" and set "Show Hidden Files". On linux, there really aren't many hidden files, and changing the configuration for .files is easy enough in Gnome and XFCE. How can I set up OS X in a similar way. I am not new to computers, and I am fully aware that deleting system files can damage or even irreparably disable a OS install. Therefore, If I intentionally try to delete a file, or move something, it's probably intentional, and I am willing to accept the consequences in any case. At this point, I have fallen back to doing everything through the command line (which takes forever), because Finder is practically unusable. (As for what I am attempting to do, I also asked about GUI changes here.)

• lighttpd domains and url matching

  - by Manuel

  I'm trying to configure lighttpd so that: www.domain1.org/admin uses config1 any other URL on www.domain1.org uses config2 any url on www.domain2.org uses config2 So basically, domain1 and domain2 should use the same configuration except for when domain1 is accessed via an URL that starts with /admin I tried so far a number of variations, including this one: $HTTP["host"] =~ "domain1.org" { $HTTP["url"] =~ "^/admin" { // config1 alias.url = ("/media/admin" => "/usr/share...", "/static" => "/var/www/...") url.rewrite-once = ( "^(/media/admin.*)$" => "$1", "^(/static.*)$" => "$1", "^/favicon\.ico$" => "/media/favicon.ico", "^(/.*)$" => "/application.fcgi$1", ) server.document-root="/var/www/application" fastcgi.debug = 1 fastcgi.server = ( "/application.fcgi" => ( "main" => ( "socket" => "/var/www/application/application.sock", "check-local" => "disable", ) ), ) } else $HTTP["url"] !~ "^/admin" { // config2 } $HTTP["host"] !~ "domain1.org" { // config2 } But no matter what, accessing domain1.org/admin yields a 404. Is there anything that I am missing?

• Portforwarding Combine Several Ports

  - by kiraitachi

  Hi I got a Raspberry Pi at A.A.A.B in my local network and I have set up a DMZ on my router so that any incoming traffic that comes to my router gets redirected to my raspberry pi wich I can connect via NO-IP adress. The problem is that I want to set up portforwarding since i got several services running on my Pi like SSH, torrent webgui, webalbum, etc. I had this already done before long time ago, but I forgot a bit the syntax and cant get to set it up. Router Help says: The Application allows you to do port forwarding, but only have the ports open when data flowing out of the trigger ports. When a program sends data out on outgoing ports called trigger ports, the device then allows incoming data on the open ports specified in your port triggering configuration. 1.Trigger Port Start Trigger Port Start Specify the start port on the device that would trigger the device to open ports for incoming data. 2.Trigger Port End Specify the end port on the device that would trigger the device to open ports for incoming data. You can enter a port number the same as the trigger port start or enter a larger port number to specify a port range. 3.Trigger Traffic Protocol Type Select the trigger traffic type. Open Port Specify all the ports to be opened. It's content could be: A single port only. A port range only. Start open port number and end port number should be separated by "-" . Combined several single port and several port ranges. Each single port or port range should be separated by "," . Open Traffic Protocol Type Select the open traffic type. This are the fields: http://es.tinypic.com/view.php?pic=n5lv1k&s=8 I think this is the syntax 1-7999,8001-9090,9092-65535. But each time I want to add it gives me an error. Any ideas?

• Is there a way to use VirtualBox without using it's resource registry?

  - by Catskul

  Summary VirtualBox seems to want everything to be "registered" which makes it much more annoying to work with on the command line. I'm attempting to create an automated script which will create, move, start, stop, and destroy virtual machines and virtual disks. Requiring registration will complicate the task for the following reasons. leaves state information around that can cause unpredicted edgecases causing scripts to fail. creates potential name space collisions for multiple process creating VMs with the same name moving/copying resources on the same machine is more complicated because references in the registry need to be updated copying resources (disk + vm combination) to another machine require reconfiguration once they reach their target machine, and require the transfer of extra meta data to do the reconfiguration. If something unexpectedly fails, and an unregister thus fails to happen, left over configuration information can cause problems in subsequent runs. Use Case My specific use case is for a continuous integration server which creates and destroys VMs and Disk images potentially with the same name, and would require more logic to deal with the registry's statefulness. Imaginary Example It seems that I should just be able to for example (using some imaginary and/or incorrect commands): mkdir foobar customdiskimg_script ./foo/foo.vdi vboxmanage createvm --name "foo" --ostype Linux --basefolder ./foo/foo.xml vboxmanage storagectl ./foo/foo.xml --name foo --add ide vboxmanage storageattach --storagectl foo --medium ./foo/foo.vdi ./foo/foo.xml vboxmanage startvm ./foo/foo.xml TLDR Is there a way to use virtualbox without "registering" harddisks and VMs?

• file read performance degrades as number of files increases

  - by bfallik-bamboom

  We're observing poor file read IO results that we'd like to better understand. We can use fio to write 100 files with a sustained aggregate throughput of ~700MB/s. When we switch the test to read instead of write, the aggregate throughput is only ~55MB/s. The drop seems related to the number of files since the throughput for read and write are comparable for a single file then diverge proportionally as we increase the number of files. The test server has 24 CPU cores, 48GB of memory, and is running CentOS 6.0. The disk hardware is a RAID 6 array with 12 disks and a Dell H800 controller. This device is partitioned with ext4 using the default settings. Increasing the readahead (using blockdev) improves the read throughput significantly but it still doesn't match write speed. For instance, increasing the readahead from 128KB to 1M improved the read throughput to ~145MB/s. Is this a known performance issue in our OS/disk/filesystem configuration? If so, how can we tell? If not, what tools or tests can we use to further isolate the issue? Thanks.

• Snort not detecting outgoing traffic

  - by Reacen

  I'm using Snort 2.9 on windows server 2008 R2 x64, with a very simple configuration that goes like this: # Entire content of Snort.conf: alert tcp any any -> any any (sid:5000000; content:"_secret_"; msg:"TRIGGERED";) # command line: snort.exe -c etc/Snort.conf -l etc/log -A console Using my browser, I send the string "_secret_" in the url to my server (where Snort is located). Example: http://myserver.com/index.php?_secret_ Snort receives it and throws an alert, it works, no problem ! But when I try something like this : <?php // (index.php) header('XTest: _secret_'); // header echo '_secret_'; // data ?> If I just request http://myserver.com/index.php, it does not work or detect anything from the outgoing traffic even though the php file is sending the same string both in headers and in data, with no compression/encoding or whatsoever. (I checked using Wireshark) This looks to me like a Snort problem. No matter what I do it only detects receiving packets. Did anyone ever face this sort of problems with Snort ? Any idea how to fix it ?

• sudo or acl or setuid/setgid?

  - by Xavier Maillard

  for a reason I do not really understand, everyone wants sudo for all and everything. At work we even have as many entries as there are way to read a logfile (head/tail/cat/more, ...). I think, sudo is defeating here. I'd rather use a mix of setgid/setuid directories and add ACL here and there but I really need to know what are the best practices before starting up. Our servers have %admin, %production, %dba, %users -i.e many groups and many users. Each service (mysql, apache, ...) has its own way to install privileges but members of the %production group must be able to consult configuration file or even log files. There is still the solution to add them into the right groups (mysql...) and set the good permission. But I do not want to usermod all users, I do not want to modify standards permissions since it could change after each upgrade. On the other hand, setting acls and/or mixing setuid/setgid on directories is something I could easily do without "defacing" the standard distribution. What do you think about this ? Taking the mysql example, that would look like this: setfacl d:g:production:rx,d:other::---,g:production:rx,other::--- /var/log/mysql /etc/mysql Do you think this is good practise or should I definetely usermod -G mysql and play with standard permissions system ? Thank you

• Unable to connect to SQL Database (can the password be reset)

  - by user45450

  I have recently joined a company which has an SQL 2005 Server running a few databases. The server looks like no one has touched it in a couple of years and has this week it ran out of disk space. After a quick hard drive scan it looks like some of the databases have become a little bloated and particularly the Sharepoint_config~*~_log and WSS_Content_log.ldf have grown to about 15GB. I have been able to log into a couple of the other databases and use the shrinkfile command to free up disk space but for some reason I am unable to log into the sharepoint and Microsoft#SSEE databases (which gives me the "cannot connect to Sharepoint, a network related or instance specific error occurred..." when I try and connect) I can see that the database is running via the SQL surface configuration and I have made sure that the remote connection settings allow me to connect locally but I am still unable to log in either with windows authentication or locally. Is there any way to reset or recover the database login details so I can get in? ( I have tried logging in with all the administrative passwords I can find and after tracking down the company who installed it in the first place I found out that they have no idea what the password could have been)

• Oracle 11g Data Guard over a WAN

  - by Dave LeJeune

  Hi - We are in process of looking at using Oracle's Data Guard to replicate our 11g instance from a colo facility in Washington DC to Chicago. To give some basics we have approximately 25TB of storage and a healthy transaction rate in the 1-2K/sec range. Also, because we are processing data in real-time we have a 24x7x365 requirement for processing data. We don't have any respites as far as volume except for system upgrades (once every few months) where we take the system offline but then course experience a spike in transactions when we bring the system back on-line. Ideally we would want the second instance in the DG configuration semi-online in a read-only fashion for reports/etc. We evaluated DG in 10g and were not overly impressed and research seemed to show that earlier versions had issues with replication over a WAN but I have heard good things about modifications the product has gone through w/ 11g. Can anyone confirm an instance of this size and transaction rate being replicated over a WAN and if so what is the general latency? An information or experiences with a DG implementation that is of this size and scope would really be helpful (or larger - I also realize we are still relatively small compared to many others out there). Many thanks in advance.

• building a debian base image

  - by Michael

  Is there a preferred way to create base images for Debian-based customized installations? We are currently going with multistrap but although it's better than hand-crafted chroot stuff, it still has a lot of edges and corners. Is there a more reliable and less error-prone way to produce a root filesystem of a Debian installation with some additional .debs installed? (I don't want to send out a Debian installer with a preseed file though.) Addendum 1: To clarify things a bit: We are delivering some kind of software appliance to our customers. That is, a debian operating system, with some additional software packages -- both our own and third-party ones -- and some configuration changes. To ease the installation process, we have an installer that does nothing more than partitioning, copying files to the partitions and setting up grub. So it's basically an image-based installer. So we are basically running the debian installation ourselves and just distribute the already installed operating system. The question is about the installation part. I want to have that as easy and robust as possible, and of course, it should be an automated process.

• Group Policy - Published software not upgrading

  - by VokinLoksar

  I'm testing this with mercurial MSIs, but it's the same for other packages. I've created a new group policy and added an old version of mercurial to User software installation as a Published package. On a Windows 7 client I install the package through Programs and Features. The installation works fine. Now, I would like to publish an updated version of mercurial. I create a new Published package. Under 'Upgrades' I configure it to replace (upgrade also doesn't work) the old version and mark this upgrade as 'Required'. The old package is not removed. The Windows 7 client is then restarted. When I log back in, I see a status message saying something like 'Removing managed software Mercurial ...'. There is no message about installation of the upgrade. If I look in Programs and Features, I can see the new version of mercurial listed. However, the actual mercurial directory under Program Files is missing. It's as though the installation recorded information about the MSI, but didn't actually install anything after removing the old version. As I mentioned, this isn't specific to mercurial. I've tried using other apps and have yet to find one that can be upgraded via a Published package. Using Assigned packages in Computer Configuration works without problems, but I would like this software to be optional rather than required. Ideas?

• Postfix not delivering from external senders and not logging anything

  - by simendsjo

  Some semi-recent upgrades must have broken my postfix+dovecot configuration, but I'm having problems finding out what the cause is. My domain is simendsjo.me with the MX record mail.simendsjo.me. I can send mail to both local and external recipients, and it delivers mail from internal mailboxes. The problem is that mail from external senders isn't delivered, and nothing is logged at all. The external sender also doesn't receive any errors. I have no idea where to ever start looking as nothing is logged at all when external mail is sent to my server. So the first issue would be: How can I turn on some debug messages for postfix? I've tried: debug_peer_level = 2 debug_peer_list = simendsjo.me .. And _level = 999 and _list = gmail.com where I'm trying to send emails from. but nothing is logged. When sending mails from a local mailbox (but from an outside computer, not localhost), a lot is logged. I don't have any rules in iptables either. Any ideas how I can get some debug messages for postfix?

• nginx + IIS + GET

  - by Eralde

  I have nginx on pc "A" & IIS with ASP.NET on pc "B". nginx is configured like this: ... location ~ ((Web|Script)Resource.*)$ { proxy_pass "B"/$1; proxy_redirect off; proxy_set_header REMOTE_ADDR $remote_addr; proxy_set_header REQUEST_URI $request_uri; proxy_set_header HTTP_REFERER $http_referer; #proxy_set_header REQUEST_URI $request_uri; proxy_set_header QUERY_STRING $query_string; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }... but requests to "B"/WebScript?a=b&c=d aren't able to deliver GET data (a=b&c=d) to IIS part. Could anyone help with this? Edit: There's some additional info: nginx is also configured to proxy other data to Apache, running on "A" everything is fine there (at least GET is OK). configuration is the same as above, but for different location
