• TOR Proxy / Vidalia "New Identity" button not working

  - by Yisman

  I need to hide my ip from time to time. In Vidalia, I click on "New Identity". Ihen I check http://myip.ozymo.com/ to see if my IP address has changed. But, no, it hasn't. Why is that? And how can this be fixed? I tried waiting till the button gets re-enabled to make sure that its done processing the command, but still the IP address is the same. In Fiddler each request is tracked, so it's not a cached response. It's re-requested, but simply does not change. Fiddler though does show one thing interesting. Here is the raw response of many of the requests: HTTP/1.1 200 OK Content-Length: 13 Date: Mon, 23 May 2011 12:02:57 GMT Server: Apache X-Powered-By: PHP/5.2.14 Content-Type: text/html; charset=UTF-8 Age: 1 Connection: keep-alive **Warning: 110 localhost:8118 Object is stale** 26.32.120.106 What is this warning? And is this the cause?

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

  - by mgibsonbr

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

• Nginx proxy to IIS Connection Timeout

  - by MitMaro

  I am having an issue with random timeouts with a Nginx proxy connecting to an IIS machine. I have been watching a packet capture between the two servers and it seems that the IIS machine is receiving a SYN packet but is not responding with what I think should be an ACK response. Before the timeout occurs there seems to be a slower response from the IIS server. There is no unusual memory or processor usage on the IIS or Nginx machine. Some information on the servers and setup: Nginx Machine: Ubuntu 10.04 64bit Nginx 0.7.65 Amazon EC2 Windows Machine: Windows Server 2008 IIS 7 ASP.net Application in Integrated Mode Nginx Error: 2011/01/10 17:57:40 [error] 8297#0: *30 connect() failed (110: Connection timed out) while connecting to upstream, client: 209.***.***.***, server: secure.example.com, request: "GET /a/path/deliver.aspx HTTP/1.1", upstream: "http://***.***.***.****:****//another/path/deliver.aspx", host: "secure.example.com" WireShark Packets 6521.449528 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477422103 TSER=0 WS=7 6524.443239 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477422403 TSER=0 WS=7 6530.443241 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477423003 TSER=0 WS=7

• Dropped WD External Harddisk, now it's shown as "Not initialized"

  - by Phelios

  So, the WD my passport external harddisk is dropped, and after that, the computer is unable to read it anymore. I was hopping if I can just find another case to try if the harddisk is still readable, but looks like the hard drive itself is not a normal SATA or PATA drive. I think it's modified. So, I can't find another case that I can try on. In the computer, I still can see the drive in the "Disk Management", but it's shown as Uninitialized, no size, and no drive letter. I've also tried a couple of recovery tools. Some can't detect at all, there is one (find and mount software) that can detect but shows 0 size. None of them can recover the data. WD is willing to replace it with a new one, but I still need to recover the data. Any way I can recover the data? UPDATE: I tried initialized it from the windows Disk Manager, but it give error "The request could not be performed because of an I/O device error."

• Getting 404 error on MVC web-site

  - by RB

  I have an IIS7.5 web-site, on Windows Server 2008, with an ASP.NET MVC2 web-site deployed to it. The website was built in Visual Studio 2008, targeting .NET 3.5, and IIS 5.1 has been successfully configured to run it as well, for local testing. We've installed the world's simplest MVC application (the one which is created when you create a new MVC2 project in Visual Studio), and we are getting 404s on any page we try and access - e.g. <my_server>/Home/About will generate a 404. I've asked this question on StackOverflow as well, but that was before I knew it was a server issue. I have checked the following things: There are 404 entries in the IIS log, corresponding to each request. The application pool for the web-site is set to use the Integrated pipeline. The "customErrors" mode is set to off. .NET 3.5 SP1 is installed ASP.NET MVC 2 is installed I've used MVC Diagnostics to confirm all MVC DLLs are being found. ASP.NET is enabled in IIS, which we've demonstrated by running the MVC Diagnostics page. KB 2023146 did highlight that HTTP Redirection was off, so we've turned it on, but no joy. Any ideas will be greatly appreciated! Someone did suggest that there might be problems running it caused by Windows Server 2008 being 64-bit - does anyone know anything about this?

• How can I prevent Apache from asking for credentials on non SSL site

  - by Scott

  I have a web server with several virtual hosts. Some of those hosts have an associated ssl site. I have a DirectoryMatch directive in my main config file which requires basic authentication to any directory with secured as part of the directory path. On sites that have an SSL site, I have a rewrite rule (located in the non ssl config for that site), that redirects to the SSL site, same uri. The problem is the http (80) site asks for credentials first, and then the https (443) site asks for credentials again. I would like to prevent the http site from asking and thus avoid the potential for someone entering credentials and having them sent in clear text. I know I could move the DirectoryMatch down to the specific site, and just put the auth statement in the SSL config, but that would introduce the possibility of forgetting to protect critical directories when creating new sites. Here are the pertinent declarations: httpd.conf (all sites): <DirectoryMatch "_secured_"> AuthType Basic AuthName "+ + + Restrcted Area on Server + + +" AuthUserFile /home/websvr/.auth/std.auth Require valid-user </DirectoryMatch> site.conf (specific to individual site) <DirectoryMatch "_secured_"> RewriteEngine On RewriteRule .*(_secured_.*) https://site.com/$1 </DirectoryMatch> Is there a way to leave DirectoryMatch in the main config file and prevent the request for authorization from the http site? Running Apache 2 on Ubuntu 10.04 server from the default package. I have AllowOverride set to none - I prefer to handle things in the config files instead of .htaccess.

• 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.

• IIS 7.5 fails to open database after computer machine on that database server is working restarts.

  - by Jenea

  Hi. I decided to post this question also here in case the issues we have is related to sql server. There is a problem that bother me for some time. I have an asp.net mvc that uses NHibernate for modeling the database. The infrastructure is the following: Windows 2008 R2 for all virtual machines. IIS 7.5 is working on one virtual machine. Sql Server 2008 is working on another virtual machine. We have couple of databases, two that stores application data and one that registers all unhandled exceptions. Sometimes virtual machine that hosts database server restarts (in the middle of the night, not quite sure about the reason) after that connection to the databases that stores application data is not working and as result there are thousands of unhandled exceptions that get registered in the third database. Important to mention that databases are accessible from Management Studio. The problem is solved by resetting IIS. Connetion are handled via NHibernateUtil class which opens and closes session at each request.

• 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?

• Denying access to website via htaccess based on http header

  - by neekster

  I've been trying for ages to get this to work and I can't put my finger on it. What I'm trying to do is block access to a site from a number of countries, based on the CF-IPCountry header added by CloudFlare. I figured htaccess was a suitable way to do this. We are running LiteSpeed 4.2.4 on top of DirectAdmin for a control panel. The problem we having is the htaccess rule doesn't seem to do anything. Here's the rule we tried: SetEnvIf CF-IPCountry AU UnwantedCountry=1 Order allow,deny Deny from env=UnwantedCountry Allow from all That makes no difference at all, connections are still accepted. Just to check that the rule was at least being processed, I changed Allow from all to Deny from all, and connections were refused. So it appears to be a problem wit the variable. Here's the relevant headers that come in with the request. Connection: Keep-Alive Accept-Encoding: gzip CF-Connecting-IP: xx.xx.xx.xx CF-IPCountry: AU X-Forwarded-For: xx.xx.xx.xx.xx CF-RAY: c9062956e2d04b6 X-Forwarded-Proto: http CF-Visitor: {"scheme":"http"} Zone-Name: xx.com.au Hopefully someone can help me out, this has been driving me nuts for too long. Thanks

• 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,

• 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?

• Protect all XML-RPC calls with HTTP basic auth but one

  - by bodom_lx

  I set up a Django project for smartphone serving XML-RPC methods over HTTPS and using basic auth. All XML-RPC methods require username and password. I would like to implement a XML-RPC method to provide registration to the system. Obviously, this method should not require username and password. The following is the Apache conf section responsible for basic auth: <Location /RPC2> AuthType Basic AuthName "Login Required" Require valid-user AuthBasicProvider wsgi WSGIAuthUserScript /path/to/auth.wsgi </Location> This is my auth.wsgi: import os import sys sys.stdout = sys.stderr sys.path.append('/path/to/project') os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings' from django.contrib.auth.models import User from django import db def check_password(environ, user, password): """ Authenticates apache/mod_wsgi against Django's auth database. """ db.reset_queries() kwargs = {'username': user, 'is_active': True} try: # checks that the username is valid try: user = User.objects.get(**kwargs) except User.DoesNotExist: return None # verifies that the password is valid for the user if user.check_password(password): return True else: return False finally: db.connection.close() There are two dirty ways to achieve my aim with current situation: Have a dummy username/password to be used when trying to register to the system Have a separate Django/XML-RPC application on another URL (ie: /register) that is not protected by basic auth Both of them are very ugly, as I would also like to define a standard protocol to be used for services like mine (it's an open Dynamic Ridesharing Architecture) Is there a way to unprotect a single XML-RPC call (ie. a defined POST request) even if all XML-RPC calls over /RPC2 are protected?

I have an SSH access to this machine at port 22.There are some virtual machines running on this server and then at the back of every thing many other Operating systems are working. Now Since I am behind the data centers firewall my supervisor asked me if I can do some thing by which I can give many people on Internet access to these virtual machines directly. I know if I were allowed to get traffic on port other than 22 then I can do a port forwarding. But since I am not allowed this so what can be a solution in this case. The people who would like to connect might be complete idiots.Who may be happy just by opening putty at their machines or may be even filezilla.I have configured an Apache Reverse Proxy for redirecting the Internet traffic to the virtual machines on these hosts.But I am not clear as for SSH what can I do.So is there some thing equivalent to an Apache Reverse Proxy which can do similar work for SSH in this situation. I do not have firewall in my hands or any port other than 22 open and in fact even if I request they wont allow to open.2 times SSH is not some thing that my supervisor wants.

• 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?

• 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.

• 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.

• 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?

• 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.)

• 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?
