Setup windows 2012 AD in Hyper-V for a Test environment

- by hub

Im trying to setup a Windos 2012 R2 test environment on my work computer (a laptop). I have a AD, DHCP and DNS server on server A, and a client connecting to the doman and that works. The client can ping the AD server and gets a valid IP adress. If I ping google.com from the client I get the IP adress but I dont get any responses (request time out). If i ping google.com from server A it works as it should. Server A have a connection to the Internet through a "external network switch" in hyper-v, which gets its internet from a router and the client is connected to a "internal network switch". May the poblem be that server A is behind a router? Can I make this solution to work regadless the network my laptop is connected to? At home i have one IP adress, at work its a totally different range. What I would like is to use my laptops internet connection, regardless wifi or wired, to act as incomming internet, is this possible?

LDAP Account Locked Out Sporadically after Password change - Finding the source of invalid attempts

- by CityView

On a small network of machines (<1000) we have a user whose account is being locked out after an indeterminate interval following a password change. We are having severe difficulties finding the source of the invalid logon attempts and I would appreciate it greatly if some of you could go through your thought process and the checks you would perform in order to fix the problem. All I know for sure is that the account is locked out several (5+) times a day, I can't even be sure it's due to failed login attempts as there is no record of failure until the account is locked. So far I have tried; Logging the account out of everything we can think of and back in with the new password Scanning the user's box for any non standard software which might perform an LDAP lookup Checking all installed services on our production boxes to check none are attempting to run under the account Changing the user back to their old password (Problem persists so perhaps password change is a red herring) Wireshark on a box where lots of LDAP authentication is performed - Rejects only occur after account is already locked out Clearing the credential cache in - Control Panel - User Accounts - Advanced Looking at the local I'm at a loss for what to try. I am happy to try any suggestions you have in order to diagnose the issue. I think my question boils down to a simple request; I need a technique for deriving the source (Application/Host) of the invalid login attempts which are causing the account to be locked. I'm not sure if that's even possible but I suspect there must be more I can try. Many thanks, CityView

Strange 400 error with IIS 7.5 and a webservice?

- by Juw

Ok, this is a longshot. I have been pondering this for hours. I have no clue how to solve this. But maybe someone here can recognize the problem and point me to right direction. I have an IIS 7.5 server and a MSSQL database on a different server. On the IIS server there is a webservice that communicates with the MSSQL server. The problem is that when there is data that the MSSQL server needs to send back to the webservice and the webservice delivers that back to the webbrowser (JSON) i get a 400 error. Looking through the logs for the IIS there is just a 400....nothing more. When i put in a call to the service in my browsers URL field i get this: "The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service." There is NOTHING wrong with how i call the webservice. It has worked before on a different server (a dev server). Do someone have a clue on what this can be about? 400 means malformed URL...it isn´t. And why is that when there are no data to return to the user...everything works. But when there is data fetched from the MSSQL DB...the 400 error shows up. Hope someone have some tips how to solve it. Thanx in advance.

Router reporting failed admin login attempts from home server

- by jeffora

I recently noticed in the logs of my home router that it relatively regularly lists the following entry: [admin login failure] from source 192.168.0.160, Monday, June 20,2011 18:13:25 192.168.0.160 is the internal address of my home server, running Windows Home Server 2011. Is there anyway I can find out what specifically is trying to login to the router? Or is there some explanation for this behaviour? (not sure if this belongs here or on superuser...) [Update] I've run both Wireshark and netmon for a while on my home server. Wireshark captured the traffic, but didn't really show anything useful (or nothing I could make use of). A simple HTTP GET request is sent from the server (192.168.0.160) to the router (192.168.0.1), from a seemingly random port (I've seen examples from 50068, 52883), and it appears to do it twice in quick succession (incrementing port by 1), about every hour. Running netstat around the time of the failure didn't show anything (probably too long after anyway). I tried using netmon as it categorises by process, so I thought it might show a corresponding process for the port. Unfortunately, this comes in under the 'unknown' category, meaning it's basically just a slower, less useful Wireshark. I know there's not much to go on here, but does this help in anyway?

Windows Server 2008 ignores any change made to firewall

- by Maurice Courtois

I have been trying for the last 2 hours to make my Windows Server 2008 answer ping. I have tried almost every single solution I have found on the web, so far nothing work. My current setup: 2 NIC (1x Internet connection, 1x Local network) Server act as VPN server. So I set the corresponding NIC as either Public or Private. I also enable the rule for "File and Printer Sharing (Echo Request...)" for all Nic and from any IPs. I always been able to ping from the local network or the local ip while connected to the VPN. I also tried to create a specific rule for ICMP ping and disabling the firewall for all but the public nic. Regardless of all this, I still can't ping that server from Internet. Any idea suggestion what could cause this? I have the impression that when you set the server as VPN (I switch the box on when setting it up to block everything else than VPN connection) that changing anything to the firewall setting thought mmc is pointless !?!?

How to point any *.mydomain variation to localhost (for development)?

- by user41339

Hi all. I am developing a site, which will make use of any given [variation of] subdomain name part (that is, the part prefixed before the host name and, optionally, the TLD part). I would imagine that in production, that would be an easy feat - make sure the DNS for second-level domain name part points to an IP, set up Apache2 virtual host to listen on that (or any) IP port 80, and just use PHP to make decisions based on the "Host" request header. However, currently the site is localhost, since I am developing it using my workstation, so first I patched the /etc/hosts to include: 127.0.0.1 mydomain I only used one name part (arguably a custom TLD) so as to not interfere with the Internet domain names. Then I set up a VirtualHost directive for Apache 2.2 like: <VirtualHost *:80> ServerName mydomain But now I can see that f.e. example.mydomain does not point to localhost, meaning the the /etc/hosts addition is not effective for "something.mydomain". It appears the rules are taken verbatim, and also I have checked that wildcards like *.mydomain are not allowed. Is there a solution for this?

ADUC Exchange tabs - Windows 7 & Exchange 2003

- by John Gardeniers

I have the admin tools install on a Win 7 64 bit machine but would like to see the Exchange tabs in ADUC. Googling shows this is a popular request and the most common solution (and the only one which appears to work to all) is to install Exchange Server Management for Vista using esmvista.msi /q. That may well have worked on beta versions of Win 7 but is definitely not working with my OEM copy of Win 7. Can this perhaps be made to work by installing from an Exchange 2007 CD (which I don't have at this time), bearing in mind that we have Exchange 2003 only? Can someone please offer a solution that works? I figure some of you must have solved this by now. Edit: I don't know if this is relevant or not but the Win 7 machine is also running Office 2010 Pro. About the bounty I had intended to award the bounty to gWaldo for having taken the extra steps to try to help me with this issue. However, as I was about to do so my screen started scrolling and I actually clicked on the answer posted by natxo asenjo, who's answer offended me, without realising it. Perhaps if I wasn't rushing I might have noticed but that's now history.

Trouble connecting to a local SQL server instance from the web

- by dfarney

We have a small network behind a firewall (WatchGuard XTM 2 series) and network switch. On our network we have multiple instances of SQL server, but 1 in specific that I would like to be able to access remotely from our website. We have a static IP address from our ISP and then all the machines on the network have a locally assigned dynamic IP address. When trying to connect to the database from outside our network how do I get the request to be directed to the proper machine / SQL instance? Is it a parameter in my connection string or something in my firewall? A few things to rule out: 1) The firewall is allowing access from the website to our network. I added the site's IP and opened up port 1433. Also, when trying to connect and monitoring the firewall no exceptions come up as they did before I added the proper IP address. 2) Remote connections on the SQL server has been setup and enabled. I've done a lot of reading up on remote connections and I am sure it has been setup properly. I am currently getting this error message on my site: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

How should I deploy my JVM-based web application on ubuntu?

- by Pieter Breed

I've developed a web application using clojure/compojure (JVM based) and while developing I tested it using embedded jetty that runs on 0.0.0.0:8080. I would now like to deploy it to run on port 80 on ubuntu. I do dynamic virtual hosting, so any request for any host that arrives on port 80 should be handled by my application. The issues that worries me are: I can still run it embedded but I'm worried about running my app as root (needed for binding to port 80). I'm not sure if I can 'give up root' when in the JVM. Do I need to be concerned by this? besides, serving web applications is a known problem and I should be using known solutions for this (jetty or tomcat) but especially tomcat seems very heavy weight. Besides, I only have one application that listens to /* and does routing internally. (with compojure/ring). What I'm trying to say with this is that tomcat by default assigns WARs to subfolders which I don't want. So basically what I need is some very safe way of binding to port 80 on ubuntu that can with minimal interference send all requests to my app. Any ideas?

_default_ VirtualHost overlap on port 443, the first has precedence

- by Mohit Jain

I have two ruby on rails 3 applications running on same server, (ubuntu 10.04), both with SSL. Here is my apache config file: <VirtualHost *:80> ServerName example1.com DocumentRoot /home/me/example1/production/current/public </VirtualHost> <VirtualHost *:443> ServerName example1.com DocumentRoot /home/me/example1/production/current/public SSLEngine on SSLCertificateFile /home/me/example1/production/shared/example1.crt SSLCertificateKeyFile /home/me/example1/production/shared/example1.key SSLCertificateChainFile /home/me/example1/production/shared/gd_bundle.crt SSLProtocol -all +TLSv1 +SSLv3 SSLCipherSuite HIGH:MEDIUM:!aNULL:+SHA1:+MD5:+HIGH:+MEDIUM </VirtualHost> <VirtualHost *:80> ServerName example2.com DocumentRoot /home/me/example2/production/current/public </VirtualHost> <VirtualHost *:443> ServerName example2.com DocumentRoot /home/me/example2/production/current/public SSLEngine on SSLCertificateFile /home/me/example2/production/shared/iwanto.crt SSLCertificateKeyFile /home/me/example2/production/shared/iwanto.key SSLCertificateChainFile /home/me/example2/production/shared/gd_bundle.crt SSLProtocol -all +TLSv1 +SSLv3 SSLCipherSuite HIGH:MEDIUM:!aNULL:+SHA1:+MD5:+HIGH:+MEDIUM </VirtualHost> Whats the issue: On restarting my server it gives me some output like this: * Restarting web server apache2 [Sun Jun 17 17:57:49 2012] [warn] _default_ VirtualHost overlap on port 443, the first has precedence ... waiting [Sun Jun 17 17:57:50 2012] [warn] _default_ VirtualHost overlap on port 443, the first has precedence On googling why this issue is coming I got something like this: You cannot use name based virtual hosts with SSL because the SSL handshake (when the browser accepts the secure Web server's certificate) occurs before the HTTP request, which identifies the appropriate name based virtual host. If you plan to use name-based virtual hosts, remember that they only work with your non-secure Web server. But not able to figure out how to run two ssl application on same server. Can any one help me?

Configure Apache + Passenger to serve static files from different directory

- by Rory Fitzpatrick

I'm trying to setup Apache and Passenger to serve a Rails app. However, I also need it to serve static files from a directory other than /public and give precedence to these static files over anything in the Rails app. The Rails app is in /home/user/apps/testapp and the static files in /home/user/public_html. For various reasons the static files cannot simply be moved to the Rails public folder. Also note that the root http://domain.com/ should be served by the index.html file in the public_html folder. Here is the config I'm using: <VirtualHost *:80> ServerName domain.com DocumentRoot /home/user/apps/testapp/public RewriteEngine On RewriteCond /home/user/public_html/%{REQUEST_FILENAME} -f RewriteCond /home/user/public_html/%{REQUEST_FILENAME} -d RewriteRule ^/(.*)$ /home/user/public_html/$1 [L] </VirtualHost> This serves the Rails application fine but gives 404 for any static content from public_html. I have also tried a configuration that uses DocumentRoot /home/user/public_html but this doesn't serve the Rails app at all, presumably because Passenger doesn't know to process the request. Interestingly, if I change the conditions to !-f and !-d and the rewrite rule to redirecto to another domain, it works as expected (e.g. http://domain.com/doesnt_exist gets redirected to http://otherdomain.com/doesnt_exist) How can I configure Apache to serve static files like this, but allow all other requests to continue to Passenger?

Apache: How to enable Directory Index browsing at the Doc Root level?

- by Brian Lacy

I have several web development projects running on Fedora 13. I generally setup Apache to serve my larger projects as Virtual Hosts, but I've got several small projects cycling through that I don't really care to setup a VirtualHost for each one. Instead I'd like them all under a subdirectory of the main VirtualHost entry. I just want Apache to serve me the directory index when I browse to the host name. For example, the hostname projects.mydomain.com refers to /var/www/projects, and that directory contains only subdirectories (no index file). Unfortunately when I browse to the host directly I get: Forbidden You don't have permission to access / on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. But my virtual host entry in my apache config looks like this: <VirtualHost *> ServerName projects.mydomain.com DocumentRoot /var/www/projects <Directory "/var/www/projects"> Options +FollowSymlinks +Indexes AllowOverride all </Directory> </VirtualHost> What am I missing here?

JBoss https on port other than 8080 not working

- by MilindaD

We have a server with two JBoss instances where one runs on 8080, the other on 8081. We need to have HTTPS enabled for the 8081 server, firstly we tried enabling https on the 8080 port instance by generating the keystore and editing the server.xml and it successfully worked. However when we tried the same thing for 8081 it did not, note that we removed https for the 8080 server first before enabling it for 8081. This is what was used for both server.xml for 8080 and 8081. The only difference was that the port was changed from 8080 to 8081 when trying to enable https for 8081 port instance. What am I doing wrong and what needs to be changed? NOTE : When I meant enabled for 8080 I meant when you visit https:// URL:8484 you will actually be visiting the 8080 port instance. However when ssl is enabled for 8081 and I visit https:// URL:8484 I get that the web page is unavailable.

How to configure traffic from a specific IP hardcoded to an IP to forward to another IP:PORT using i

- by cclark

Unfortunately we have a client who has hardcoded a device to point at a specific IP and port. We'd like to redirect traffic from their IP to our load balancer which will send the HTTP POSTs to a pool of servers able to handle that request. I would like existing traffic from all other IPs to be unaffected. I believe iptables is the best way to accomplish this and I think this command should work: /sbin/iptables -t nat -A PREROUTING -s $CUSTIP -j DNAT -p tcp --dport 8080 -d $CURR_SERVER_IP --to-destination $NEW_SERVER_IP:8080 Unfortunately it isn't working as expected. I'm not sure if I need to add another rule, potentially in the POSTROUTING chain? Below I've substituted the variables above with real IPs and tried to replicate the layout in my test environment in incremental steps. $CURR_SERVER_IP = 192.168.2.11 $NEW_SERVER_IP = 192.168.2.12 $CUST_IP = 192.168.0.50 Port forward on the same IP /sbin/iptables -t nat -A PREROUTING -p tcp -d 192.168.2.11 --dport 16000 -j DNAT --to-destination 192.168.2.11:8080 Works exactly as expected. IP and port forward to a different machine /sbin/iptables -t nat -A PREROUTING -p tcp -d 192.168.2.11 --dport 16000 -j DNAT --to-destination 192.168.2.12:8080 Connections seem to timeout. Restrict IP and port forward to only be applied to requests from a specific IP /sbin/iptables -t nat -A PREROUTING -p tcp -s 192.168.0.50 -d 192.168.2.11 --dport 16000 -j DNAT --to-destination 192.168.2.12:8080 Times out as well. Probably for the same reason as the previous entry. Does anyone have any insights or suggestions? thanks,

ssh-add insists on passphrase

- by Sam Walton

I have a new ssh key problem. I have successfully used them for years with Heroku, Git and other servers so I can login without having to issue a passphrase. A few weeks ago, I was unable to push a git repository on my machine to my Heroku and it responded with Permission denied (publickey). Hmm. Everything else but this Heroku function still works. So I ssh-keygen -t rsa -C "newHeroku" with no passphrase (hit return so it would be empty). So I enter: sudo chmod 600 ~/.ssh/newHeroku* Then: ssh-add ~/.ssh/newHeroku.pub Returning return for the passphrase asked it exits without error. The next step is to: ssh-add /Users/sam/.ssh/newHeroku.pub To verify that it's "live" I enter: ssh-add -l To which the output is still The agent has no identities. Okay, to eliminate variables, I repeat the key generation process but entering in a passphrase for a new key. I ssh-add the new key and get the "Enter passphrase" as expected. Now this is why I'm posting here and not on a Heroku blog because ssh-add fails because the passphrase I used keeps getting rejected. It appears, even though I have no problem with my keys elsewhere, that something is wrong with passphrase because even though I get no errors, I get errors when on the one that expects a passphrase. One question, should I expect the Passphrase request for ssh-add when I have not generated a passphrase? It's been suggested that this is a clue and I offer it. Or maybe I have a poor understanding of what ssh-add is doing. Wouldn't be the first time I asked a stupid Q. Also, I'm on Lion and have updated no system updates in the few weeks of this period except application updates.

How do I stop linux from trying to mount android phone as usb storage?

When I plug in my Motorola Triumph to my fedora 17 linux box USB port, I get an endless series of errors on the linux box as it desperately attempts to mount the phone as a USB drive. Stuff like this: Jun 23 10:26:00 zooty kernel: [528926.714884] end_request: critical target error, dev sdg, sector 4 Jun 23 10:26:00 zooty kernel: [528926.715865] sd 16:0:0:1: [sdg] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE Jun 23 10:26:00 zooty kernel: [528926.715869] sd 16:0:0:1: [sdg] Sense Key : Illegal Request [current] Jun 23 10:26:00 zooty kernel: [528926.715872] sd 16:0:0:1: [sdg] Add.

Is there some udev magic I can do to make the system ignore this particular device as far as usb storage goes? I just noticed that if I tell the phone to enable USB storage, let linux recognize the new disk, then tell the phone to disable USB storage again, I get one additional log message about capacity changing to zero, but the endless spew of messages stops, so I guess one work around is to enable and disable USB right away.

Updating WordPress 3.6 to 3.7 via admin area on Nginx VPS hangs and fails

- by harryg

So I have a few WordPress sites running on my VPS (Ubuntu 12.10, Nginx, php-fpm 5.4) The sites are all on seperate vhosts and use their own config files (albeit similar to each other) and vary in complexity. One is very simple and uses minimal plugins. When I try to update core on any site via the admin area I click the "Update Now" button (which should run the script in wp-admin/update-core.php the page hangs for a minute or two before going to a blank admin page (i.e. the wp-admin menu bars and header bar are there but there is no content in the body of the page). Visiting another admin page via the still menu bar reveals that the core has not been updated. Checking the error log I see this entry: 2013/10/29 23:20:48 [error] 9384#0: *5318248 upstream timed out (110: Connection timed out) while reading upstream, client: --.---.--.---, server: www.mysite.com, request: "POST /wp-admin/update-core.php?action=do-core-upgrade HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "mysite.com", referrer: "http://mysite.com/wp-admin/update-core.php" This didn't happen in the past on older updates and the rest of the site including updating plugins works fine. Any ideas? Could it be as simple as a time-out error? I find that unlikely as the server should munch though a wp upgrade in seconds.

nginx: Rewrite PHP does not work

- by Ton Hoekstra

I've a Suffix Proxy installed and I'm using the following rewrite with wildcard subdomain DNS on: location / { if (!-e $request_filename) { rewrite ^(.*)$ /index.php last; break; } } My suffix proxy has the following URL format: (subdomain and/or domain + domain extension to proxy).proxy.org/(request-uri to proxy) I've this php code in my index.php: if(preg_match('#([\w\.-]+)\.example\.com(.+)#', $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'], $match)) { header('Location: http://example.com/browse.php?u=http://'.$match[1].$match[2]); die; } But when requested a page with a .php extension I'll get a 404 not found error: http://www.php.net.proxy.org/docs.php - HTTP/1.1 404 Not Found http://www.utexas.edu.proxy.org/learn/php/ex3.php - HTTP/1.1 404 Not Found But everything else is working (also index.php is working): http://php.net.proxy.org/index.php - HTTP/1.1 200 OK http://www.php-scripts.com.proxy.org/php_diary/example2.php3 - HTTP/1.1 200 OK http://www.utexas.edu.proxy.org/learn/php/ex3.phps - HTTP/1.1 200 OK http://www.w3schools.com.proxy.org/html/default.asp - HTTP/1.1 200 OK Somebody has an answer? I don't know why it's not working, on apache it's working fine. Thanks in advance. I've removed the location and now it's working perfectly: if (!-e $request_filename) { rewrite ^(.*)$ /index.php last; break; }

Server not accepting uploads

- by Tatu Ulmanen

I'm having a strange problem with my VPS: I can download files from it, I can use PuTTy to connect to it and all behaves normally. But sometimes, when I try to upload a file to the server or save a file via SFTP, the connection inexplicably fails. I am using jEdit to edit files remotely via SFTP. When it works, it works fine. When it doesn't, I get an error message: Cannot save: java.io.IOException: inputstream is closed Cannot save: java.io.IOException: 4: I can see that a temporary save file (#file.php#save#) is created on the server with a filesize of 0. So the connection works, but when it comes to sending the actual data, something fails. The same thing with WinSCP, but the error is different: Copying file fatally failed. Copying files to remote side failed. And I can always browse the server with PuTTy without a problem. I see nothing abnormal in any log files. Auth.log shows this when I try to save: sshd[32638]: Accepted password for - from - port 62272 ssh2 sshd[32638]: pam_unix(sshd:session): session opened for user - by (uid=0) sshd[32640]: subsystem request for sftp sshd[32638]: pam_unix(sshd:session): session closed for user - When I wait for a while (say, an hour), everything works fine again. It can't be a temporary ban, as I am still allowed to connect to the server, right? I know this may not be enough info to solve the problem, but I am grateful for any clues or bits of information that might help me. What are the possible causes for this kind of behaviour, what log files can I check for clues etc.. I'm running out of ideas!

Find slow network nodes between two data centers

- by 2called-chaos

I've got a problem with syncing big amount of data between two data centers. Both machines have got a gigabit connection and are not fully occupied but the fastest that I am able to get is something between 6 and 10 Mbit = not acceptable! Yesterday I made some traceroute which indicates huge load on a LEVEL3 router but the problem exists for weeks now and the high response time is gone (20ms instead of 300ms). How can I trace this to find the actual slow node? Thought about a traceroute with bigger packages but will this work? In addition this problem might not be related to one of our servers as there are much higher transmission rates to other servers or clients. Actually office = server is faster than server <= server! Any idea is appreciated ;) Update We actually use rsync over ssh to copy the files. As encryption tends to have more bottlenecks I tried a HTTP request but unfortunately it is just as slow. We have a SLA with one of the data centers. They said they already tried to change the routing because they say this is related to a cheap network where the traffic gets routed through. It is true that it will route through a "cheapnet" but only the other way around. Our direction goes through LEVEL3 and the other way goes through lambdanet (which they said is not a good network). If I got it right (I'm a network intermediate) they simulated a longer path to force routing through LEVEL3 and they announce LEVEL3 in the AS path. I basically want to know if they're right or they're just trying to abdicate their responsibility. The thing is that the problem exists in both directions (while different routes), so I think it is in the responsibility of our hoster. And honestly, I don't believe that there is a DC2DC connection which only can handle 600kb/s - 1,5 MB/s for weeks! The question is how to detect WHERE this bottleneck is

Methods to transfer files from Windows server to linux server

- by Raze2dust

Hi, I need to transfer webserver-log-like-files containing periodically from windows production servers in the US to linux servers here in India. The files are ~4 MB in size each and I get about 1 file per minute. I can take about 5 mins lag between the files getting written in windows and them being available in the linux machines. I am a bit confused between the various options here as I am quite inexperienced in such design: I am thinking of writing a service in C#.NET which will periodically archive, compress and send them over to the linux machines. These files are pretty compressible. WinRAR can convert 32 MB of these files into a 1.2 MB archive. So that should solve the network transfer speed issue. But then how exactly do I transfer files to linux? I could mount linux drive on windows server using samba, or should I create an ftp server, or send the file serialized as a POST request. Which one would be good? Also, I have to minimize the load on the windows server. Mount the windows drive on linux instead. I could use the mount command or I could use samba here (What are the pros and cons of these two?). I can then write the compressing and copying part in linux itself. I don't trust the internet connection to be very stable, so there should be a good retry mechanism and failure protection too. What are the potential gotchas in these situations, and other points that I must be worried about? Thanks, Hari

Why is IIS 7.5 seeing some requests as HTTP/1.0?

- by Zhaph - Ben Duguid

While trying to work out why Static File Compression wasn't working on one of our IIS servers, the error was coming back as "NO_COMPRESSION_10" which translates to: Server not configured to compress 1.0 requests Looking at the requests in Fiddler, I can see that I'm requesting HTTP 1.1, but everything is being sent back as HTTP 1.0: Request (from chrome, captured via Fiddler): GET /css/reset.css HTTP/1.1 Host: [-----].com Connection: keep-alive Cache-Control: max-age=0 If-Modified-Since: Tue, 16 Oct 2012 15:04:34 GMT User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11 Accept: text/css,*/*;q=0.1 Referer: http://[-----].com/ Accept-Encoding: gzip,deflate,sdch Accept-Language: en-GB,en;q=0.8,en-US;q=0.6 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Response from IIS: HTTP/1.0 200 OK Cache-Control: no-cache, no-store Pragma: no-cache Content-Type: text/html; charset=utf-8 Expires: -1 Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Tue, 11 Dec 2012 11:57:03 GMT Connection: close Content-Length: 108837 Other servers with the same host that I'm running this site on all respond with HTTP/1.1. How can I persuade IIS to respond with HTTP/1.1 rather than HTTP/1.0? Edit to add: Digging deeper, I can see that some responses from the server are indeed being returned compressed, so I guess really I'm trying to work out why talking to this particular server from our office seems to result in it seeing 1.0 requests, while other servers at the same co-loc don't?
