• Millions of SYN_RECV connections, no DDoS

  - by ThomK

  We have such server structure: reverse proxy (nginx) - worker (uwsgi) - postgresql / memcached. All servers are in local network behind router, with NATed external ip:ports (http/s 80/443 to proxy, and ssh 22 to all servers). Problem is, that sometimes proxy server netstat reports MILLIONS of SYN_RECV connections. From same IP / same ports. Like that: nginx ~ # netstat -n | grep 83.238.153.195 tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV [...] And this is not DDoS, because all IPs affected belongs to our website users. On side note, users says that it's not affecting them. Website is online and working, but... that particular one (from example above) told me that website is down and Firefox can't connect.

• Thoughts on moving to Maven in an enterprise environment

  - by Josh Kerr

  I'm interested in hearing from those who either A) use Maven in an enterprise environment or B) tried to use Maven in an enterprise environment. I work for a large company that is contemplating bringing in Maven into our environment. Currently we use OpenMake to build/merge and home-grown software to deploy code to 100+ servers running various platforms (eg. WAS and JBoss). OpenMake works fine for us however Maven does have some ideal features, most importantly being dependency management, but is it viable in a large environment? Also what headaches have/did you incur, if any, in maintaining a Maven environment. Side note, I've read http://stackoverflow.com/questions/861382/why-does-maven-have-such-a-bad-rep, http://stackoverflow.com/questions/303853/what-are-your-impressions-of-maven, and a few other posts. It's interesting seeing the split between developers.

• 640 enterprise library caching threads - how?

  - by JohnW

  We have an application that is undergoing performance testing. Today, I decided to take a dump of w3wp & load it in windbg to see what is going on underneath the covers. Imagine my surprise when I ran !threads and saw that there are 640 background threads, almost all of which seem to say the following: OS Thread Id: 0x1c38 (651) Child-SP RetAddr Call Site 0000000023a9d290 000007ff002320e2 Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.WaitUntilInterrupted() 0000000023a9d2d0 000007ff00231f7e Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.Dequeue() 0000000023a9d330 000007fef727c978 Microsoft.Practices.EnterpriseLibrary.Caching.BackgroundScheduler.QueueReader() 0000000023a9d380 000007fef9001552 System.Threading.ExecutionContext.runTryCode(System.Object) 0000000023a9dc30 000007fef72f95fd System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object) 0000000023a9dc80 000007fef9001552 System.Threading.ThreadHelper.ThreadStart() If i had to give a guess, I'm thinkign that one of these threads are getting spawned for each run of our app - we have 2 app servers, 20 concurrent users, and ran the test approximately 30 times...it's in the neighborhood. Is this 'expected behavior', or perhaps have we implemented something improperly? The test ran hours ago, so i would have expected any timeouts to have occurred already.

• Accessing Active Directory Role Membership through LDAP using SQL Server 2005

  - by David Neale

  I would like to get a list of Active Directory users along with the security groups they are members of using SQL Server 2005 linked servers. I have the query working to retrieve records but I'm not sure how to access the memberOf attribute (it is a multi-value LDAP attribute). I have this temporary to store the information: DROP TABLE #ADUSERGROUPS CREATE TABLE #ADUSERGROUPS ( sAMAccountName varchar(30), UserGroup varchar(50) ) Each group/user association should be one row. This is my SELECT statement: SELECT sAMAccountName,memberOf FROM OpenQuery(ADSI, '<LDAP://hqdc04/DC=nt,DC=avs>; (&(objectClass=User)(sAMAccountName=9695)(sn=*)(mail=*)(userAccountControl=512)); sAMAccountName,memberOf;subtree') I get this error msg: OLE DB error trace [OLE/DB Provider 'ADSDSOObject' IRowset::GetData returned 0x40eda: Data status returned from the provider: [COLUMN_NAME=memberOf STATUS=DBSTATUS_E_CANTCONVERTVALUE], [COLUMN_NAME=sAMAccountName STATUS=DBSTATUS_S_OK]].

• Why are my basic Heroku Apps Taking 2 seconds to load?

  - by viatropos

  I have created two very simple heroku apps to test out the service, but it's often taking several seconds to load the page when I first visit them: Cropify - Basic Sinatra App (on github) Textile2HTML - Even more basic Sinatra App (on github) All I did was create a simple sinatra app and deploy it. I haven't done anything to mess with or test the heroku servers. What can I do to improve response time? It's very slow right now and I'm not sure where to start. The code for the projects are on github if that helps. Thanks so much.

• My website just got hacked - what do I tell my boss and client?

  - by Christopher Altman

  http://www.computerworld.com/s/article/9175783/Network_Solutions_sites_hacked_again One of our clients had a WordPress website on Network Solutions shared hosting. It got hacked. The resolution is to migrate the site over to one of our dedicated, private servers. This process will take 24-36 hours to complete. What do I say to my boss and client? Do I blame Network Solutions? Do I blame WordPress (we recommended it)? Do I just tell each person it is being fixed and everything is just fine?

• Differences in behaviour between IIS and the ASP.Net Web Development Server?

  - by Kramii

  During development, I usually test ASP.Net applications using the Web Development Server (sometimes called Cassini). Occasionally, when I publish to a real IIS environment, I notice that the application behaves differently. So, what are the differences between the way that production IIS servers and the ASP.Net Web Development Server behave? I don't mean differences in feature sets (clearly IIS has lots of features that are not present in WDS), but differences in the way they handle ASP.Net. BTW: There are a few differences noted in the responses to this question, but I am sure there must be more.

• Bypassing rack version error using Rails 2.3.5

  - by Matt

  I'm currently on Dreamhost attempting to run a Rails 2.3.5 app. Here is the situation, Dreamhost's servers have Rails 2.2.2 installed. Of course, I can't update a shared host's rails version, so I froze my Rails in vendor. Rails 2.3.5 requires the rack v1.0.1 gem. Dreamhost uses the rack v1.0.0 gem. So when I try to define: config.gem "rack", :version => "1.0.1" I get: can't activate rack (~> 1.0.1, runtime) for [], already activated rack-1.0.0 for [] So what I really need to do is bypass my app's request to use 1.0.1, and use Dreamhost's 1.0.0. Does anyone know how to configure this? Is it even possible? Thanks for the help.

• IIS load balancing and site deployment

  - by KLC

  Hi, currently I have a site sits on one IIS7 server. When we deploy a new version of the site, we bring the site down and display an offline page. What I really want is have two same exact copies of the site sits in one IIS 7 server and load balance users among both servers. when we deploy a new version of the site, we will bring site1 down (users in site1 automatically routes to site2 on next postback), when site1 deployment is complete, bring site2 down (users in site2 being routes to site1 on next postback). is this even possible?

• Ask a DNS server what sites it hosts - and how to possibly prevent misuse

  - by Exit

  I've got a server which I host my company website as well as some of my clients. I noticed a domain which I created, but never used, was being attacked by a poke and hope hacker. I imagine that the hacker collected the domain from either hitting my DNS server and requesting what domains are hosted. So, in the interest of prevention and better server management, how would I ask my own DNS server (Linux CentOS 4) what sites are being hosted on it? Also, is there a way to prevent these types of attacks by hiding this information? I would assume that DNS servers would need to keep some information public, but I'm not sure if there is something that most hosts do to help prevent these bandwidth wasting poke and hope attacks. Thanks in advance.

• Why does Java read its default settings from the system

  - by Bozho

  Java is reading the locale, timezone and encoding information (and perhaps more) from the system it is installed on. This often brings bad surprises (brought me one just yesterday). Say your development and production servers are set to have TimeZone GMT+2. Then you deploy on a production server set to GMT. a 2-hour shift may not be easy to observe immediately. And although you can pass a TimeZone to your calendars, APIs might be instantiating calendars (or dates) using the default timezone. Now, I know one should be careful with these settings, but are easy to miss, hence make programs more error-prone. So, why doesn't Java have its own defaults - UTF-8, GMT, en_US (yes, I'm on non-en_US locale, but having it as default is fine). Applications could read the system settings via some API, if needed. Thus programs would be more predictable. So, what is the reason behind this decision?

• dynamic log4net appender name?

  - by sanjeev40084

  Let's say i have 3 smtp appenders in same log4net file whose names are: <appender name = "emailDevelopment".. /> <appender name = "emailBeta".. /> <appender name = "emailProduction".. /> Let's say i have 3 different servers(Dev, Beta, Production). Depending upon the server, i want to fire the log. In case of Development server, it would fire log from "emailDevelopment". I have a system variable in each server named "ApplicationEnvironment" whose value is Development, Beta, Production based on the server names. Now is there anyway i can setup root in log4net so that it fires email depending upon the server name. <root> <priority value="ALL" /> <appender-ref ref="email<environment name from whose appender should be used>" /> </root>

• Boost Thread Specific Storage Question (boost/thread/tss.hpp)

  - by Hassan Syed

  The boost threading library has an abstraction for thread specific (local) storage. I have skimmed over the source code and it seems that the TSS functionality can be used in an application with any existing thread regardless of weather it was created from boost::thread --i.e., this implies that certain callbacks are registered with the kernel to hook in a callback function that may call the destructor of any TSS objects when the thread or process is going out of scope. I have found these callbacks. I need to cache HMAC_CTX's from OpenSSL inside the worker threads of various web-servers (see this, detailed, question for what I am trying to do), and as such I do not controll the life-time of the thread -- the web-server does. Therefore I will use the TSS functionality on threads not created by boost::thread. I just wanted to validate my assumptions before I started implementing the caching logic, are there any flaws in my logic ?

• How to have a PHP Website tool with a version check

  - by Sara

  Hi, So I work on a small php website tool that a few people use and what I'm looking to have added is a little version checker in it. The tool is normally hosted by others on different servers/domains/whatever have you so I'm having a bit of a trouble figuring out how I can accomplish this and do so in the best possible method. So what I'm looking to do is have a webpage that just has a number on it which is the latest version. Lets say 3.2.2 is displayed on www.myawesomephptool.com/version.html in some way shape or form . Now on their installation when they open up their admin page it pulls in that 3.2.2 as the latest version to see if they are on that version. So trying to keep it simple on requirements too.

• Why is J2ee/EJBs a dying Trend?

  - by Taranfx

  I might be wrong on this, but I no longer see heavy Business and Web services being hosted using J2ee technologies (Especially EJBs). Having known the power and scalability of J2ee applications, what is keeping developers/decision makers to restrict themselves to Core Java (POJOs) or even other web technologies like PHP, python. Is it the development time? Is it the Ease of configuration? (I feel this should not be a strong reason with Java EE 6, things are simplified) Of course scripting languages are faster to develop, we cannot ignore the fact that they are inherently not-as-scalable as Java Applications are (using App servers)

• .Net System.Net.HttpWebRequest & Authentication Cookies

  - by James

  I would like to know if the following is possible: As part of the PageLoad of an ASP.Net page request: Use HttpWebRequest (POST) to make a request to a forms authentication webpage of a different web application Examine the response to see if the authentication succeeded (identifiable if an authentication cookie has been set) If it fails, then finish the ASP.Net page request, which will display a message saying "couldn't auto-login" or some such thing If success, then instead of completing the ASP.Net page lifecycle, use "Response.Write" to send the response from the HttpWebRequest back to the browser (thus essentially displaying the webpage from the HttpWebRequest) If the above is possible, then, is there also a way to transfer the authentication cookie from the HttpWebResponse to the requesting browser? My gut feeling is probably not - but if this is the case, then how do proxy servers handle such things? Is that not essentially what they are doing? Thanks for any help

• How to limit / throttle bandwidth with *multiple* connections

  - by Led

  I'm writing an app in C# that downloads concurrently (in different threads) using multiple connections to multiple servers, and I'd like to be able to limit the used bandwidth. For a single connection the solution would be simple; I'd use the solution posted here : http://www.codeproject.com/KB/IP/Bandwidth_throttling.aspx which calculates a sleep-time for the single connection. I'd like to know what the best way is to do this for multiple connections. Using the ThrottledStream posted above and dividing the bandwidth (say 2MB/sec) evenly among the connections isn't right, if I'd have 3 very slow connections and 1 very fast one they'd all be capped to 512kb/sec, so the fast one won't go above 512kb/sec and the other 3 wouldn't even make that. The preferred solution I think is to cap only the fastest connection(s) so the slower connections are used optimally. Does anyone have any experience with this, example code or any advice ?

• ASP.NET Web App to compare performance on different hardware?

  - by Guy

  I'm looking for an open source C# ASP.NET Web App that can be loaded onto 2 or more dedicated servers and provide me with metrics on how that server is performing. E.g. Click on a page and the app does a number of in-memory iterations and/or calculations to test processor throughput. Another page would do a bunch of disk access and report on that. I could put one together myself but there might already be something out there with a whole ton of tools in it to do this. I would imagine that I'm not the first one that would want to compare two machines for use as a web server.

• Can not clone git repo to server

  - by Classified

  I'm running the same command on 2 different servers. One works, the other doesn't. I'm running git clone https://blah.com:8443/blah.git On server A, it works fine. I get the objects, files, etc. no problems. On server B, I get the following message. git clone https://blah.com:8443/blah.git Cloning into 'blah'... error: Peer certificate cannot be authenticated with known CA certificates while accessing https://blah.com:8443/blah.git/info/refs?service=git-upload-pack fatal: HTTP request failed Does anyone know what this means or what I need to do to get this to work? Thanks in advance for any help you can give me.

• Mono Project: How to install Mono framework on Red Hat Linux which is compiled on centOS ?

  - by funwithcoding

  We have Red Hat Enterprise Linux servers at work place. However we dont have Red Hat Linux desktops. So I used CentOS 5.4 to compile the Mono sources and generated the Mono framework for CentOS and tested with some sample codes and I am satisfied. I want to transfer this compiled framework to Red Hat Enterprise Linux 5. How Can I do that? Do I have to compile the Mono framework statically or do I have to copy the linked libraries as well? I am not familiar with linux much. Any help is highly appreciated.

• sem_open() error: "undefined reference to sem_open()" on linux (Ubuntu 10.10)

  - by Robin

  So I am getting the error: "undefined reference to sem_open()" even though I have include the semaphore.h header. The same thing is happening for all my pthread function calls (mutex, pthread_create, etc). Any thoughts? I am using the following command to compile: g++ '/home/robin/Desktop/main.cpp' -o '/home/robin/Desktop/main.out' #include <iostream> using namespace std; #include <pthread.h> #include <semaphore.h> #include <fcntl.h> const char *serverControl = "/serverControl"; sem_t* semID; int main ( int argc, char *argv[] ) { //create semaphore used to control servers semID = sem_open(serverControl,O_CREAT,O_RDWR,0); return 0; }

• Web App for smartphones in ASPX

  - by Ryan Knoll

  I have been looking around recently to try and find a good place to learn how to start making my website more smartphone friendly when it is visited by an iPhone, android, or blackberry. This is something like what Digg.com does when it is visited by a smartphone. I have found a few tutorials for PHP but none for ASPX, and all I have is windows servers. Could anyone point me in the right direction, and show me were to find a quick run through on how to do something like this? I am a bit lost. :(

• Server Development Tool?

  - by aloneguid

  Hi, For my programming tasks I use about 2-3 remote servers to deploy and run my code against different conditions. This cannot be emulated locally as the server configuration requires powerful hardware. Most of time I need to stop service, update binareis, start service, view logs in realtime, download logs. Currently I'm doing this manually and over time this becomes a real pain in the ass, especially because the environment is not ideal in terms of network badwidth, reliability etc. I just wonder if someone from server programmers have the similar problems and how do you bear with them. Any special tools/hints/secrets?

• Using Linux vs Windows for development

  - by Philipp Lenssen

  On my servers I run everything on Linux/ Apache, but for offline preparation before upload of the projects I'm using Windows (Vista) with a local Apache/ WAMP, PHP, Python, GD_image installation and so on. My question, would it be much easier in terms of setting up a good environment if I were to use Linux, e.g. Ubuntu distribution, as development OS for these things? Would you know some pros and cons when it comes to Windows vs Linux in terms of web development? (As I'm using mostly web apps these days, switching the OS might be less of a problem. I would need a good replacement for my image editor, though, as I prefer Corel PhotoPaint and PSP4 over Gimp, last time I tried.)

• Can IIS admin change password of Windows Service account

  - by sweta Jha

  We have a service account defined for anonymous access which is used for several web sites hosted on the web server. This account has access to several network resources like report server, file servers and so on. While deploying a new web site, we used the same service account for anonymous access. IIS takes the username/password for the account and then a dialog opens for confirm password. Accidently, we gave a wrong password in both the text boxes, the new site with wrong password is working fine but all other previously hosted sites which were using the service account, started giving the unautorized access error. Is it possible that when we entered wrong password for the new web site, the password of the account got reset and all sites stopped functioning?
