  • Nameserver not resolving or domain not pingable [closed]

    - by Ricky
    Sorry, if anyone can think of a better title please change it! I want to host my own websites from home. For testing purposes, I have a virtual machine running a trial version of Windows Server 2008 Enterprise. Note I currently run a VPS and host my own websites but due to a nice speed upgrade on our line I now want to host from home. I have several domains but I wanted to test with one, that is rickyoleary.com. Our ISP does not provide static IP addresses unless we have a business account so I've been looking at no-ip.com. I admit my networking isn't the best, hence this question but I've been bashing my head all day on this one. I created a host name, muffinbubble.no-ip.org which runs on IP: 86.148.124.15. I've setup IIS on the server with a simple test page. I've then forwarded port 80 traffic from the router and from what I can see, it's working. If I access my website (I was unable to link to this for some reason so please copy and paste this) - http://86.148.124.15/ - I see my test page. So the next step was to create my nameservers. This domain is with namecheap.com so I created my nameservers, ns1.rickyoleary.com and ns2.rickyoleary.com. Both these point to the same IP (and yes, that will be changed after testing), the same IP as above: 86.148.124.15. On the server itself I have set up DNS entries as below which I believe to be correct and added rickyoleary.com and www.rickyoleary.com in the host headers (or bindings) in IIS 7.0. If I try and look up my domain, rickyoleary.com it shows ns1.rickyoleary.com and ns2.rickyoleary.com as the nameservers. I then tried to use just-ping.com on my nameserver ns1.rickyoleary.com. I get 100% packets lost, but the correct IP address is returned (I'm guessing the router does not allow pings, but is still accessible...). I get no response when pinging rickyoleary.com. Here's the problems: I cannot ping ns1.rickyoleary.com or ns2.rickyoleary.com from a command prompt. I'm not sure if this is an issue. When I added the nameservers in Windows Server 2008 and clicked 'resolve' a message box displays stating "No such host is known". I cannot ping rickyoleary.com. rickyoleary.com is not showing my test page on my server. Now - please note, I've waited around 6 hours for propagation. From my experience, although you're told to wait 24 - 48 hours, the changes are normally pretty quick so perhaps I'm being impatient or naive to think it should all be working fine until then. I would really appreciate some help here. Thanks.

  • Setting up a "cookieless domain" to improve site performance

    - by Django Reinhardt
    I was reading in Google's documentation about improving site speed. One of their recommendations is serving static content (images, css, js, etc.) from a "cookieless domain": Static content, such as images, JS and CSS files, don't need to be accompanied by cookies, as there is no user interaction with these resources. You can decrease request latency by serving static resources from a domain that doesn't serve cookies. Google then says that the best way to do this is to buy a new domain and set it to point to your current one: To reserve a cookieless domain for serving static content, register a new domain name and configure your DNS database with a CNAME record that points the new domain to your existing domain A record. Configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain. In your web pages, reference the domain name in the URLs for the static resources. This is pretty straight forward stuff, except for the bit where it says to "configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain". From what I've read, there's no setting in IIS that allows you to say "serve static resources", so how do I prevent ASP.NET from setting cookies on this new domain? At present, even if I'm just requesting a .jpg from the new domain, it sets a cookie on my browser, even though our application's cookies are set to our old domain. For example, ASP.NET sets an ".ASPXANONYMOUS" cookie that (as far as I'm aware) we're not telling it to do. Apologies if this is a real newb question, I'm new at this! Thanks.

  • Issues connection to Ubuntu via PuTTy

    - by user1787262
    I'm not sure this is the appropriate stack exchange site to post this question on. If not, please flag this for migration. I am trying to use PuTTy ssh into my ubuntu machine which is wirelessly connected to the same network. I originally ran ifconfig to get my ubuntu machines private network IP address. I then verified that ssh was running, I even ssh'd into my school network and then into the ubuntu machine itself. No problems yet. On my windows 8 machine I ran ipconfig to get my private network IPv4 address. I then pinged my ubunty machines IP and 100% of packets were received. I figured, "OK we are ready to use PuTTy to connect to my Ubuntu Machine". Keep in mind this was my first time using PuTTy. I tried entering the IP of my ubuntu machine in the PuTTy Config GUI but I got a connection timeout. At this moment I don't really know what's going on, SSH is running on port 22 of my Ubuntu machine and I can ping the machine why is it not connecting? (I tried [username]@ip too). So I went on my Ubuntu machine and ran nmap -sP 192.168.0.1/24 and found that my windows machines IP did not show up, the host is down. I'm at a lost in something I am not very familiar with. Would anyone be able to help me or direct me to some resources that would trouble shoot my problem? Thank you EDIT (ADDITION): tyler@tyler-Aspire-5250:~$ nmap -v 192.168.0.123 Starting Nmap 6.40 ( http://nmap.org ) at 2014-06-06 01:56 MDT Initiating Ping Scan at 01:56 Scanning 192.168.0.123 [2 ports] Completed Ping Scan at 01:56, 3.00s elapsed (1 total hosts) Nmap scan report for 192.168.0.123 [host down] Read data files from: /usr/bin/../share/nmap Note: Host seems down.

  • Something very strange with network

    - by Rodnower
    Hello, I have Windows 7 and I have very strange thing with my network. Some time I was connected through wireless router and my IP was 192.168.2.103, router's IP was 192.168.2.1 and some other IP was 192.168.2.100. The last I get from page "active DHCP clients" of web interface of the router and from "wireless clients" I may to see that 192.168.2.100 not (!) belong to my MAC address. Router build by EDimax. So after that I disabled wireless function of the router and restarted it. In this time I had not ping to 192.168.2.1. Also I had not any other connection, not wireless nor cable, but (!) I still had ping to 192.168.2.100 and I not understand what this voodoo is...

  • Wrappers/law of demeter seems to be an anti-pattern...

    - by Robert Fraser
    I've been reading up on this "Law of Demeter" thing, and it (and pure "wrapper" classes in general) seem to generally be anti patterns. Consider an implementation class: class Foo { void doSomething() { /* whatever */ } } Now consider two different implementations of another class: class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething() { _foo.doSomething(); } } And the ways to call said methods: callingMethod() { Bar1.getFoo().doSomething(); // Version 1 Bar2.doSomething(); // Version 2 } At first blush, version 1 seems a bit simpler, and follows the "rule of Demeter", hide Foo's implementation, etc, etc. But this ties any changes in Foo to Bar. For example, if a parameter is added to doSomething, then we have: class Foo { void doSomething(int x) { /* whatever */ } } class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething(int x) { _foo.doSomething(x); } } callingMethod() { Bar1.getFoo().doSomething(5); // Version 1 Bar2.doSomething(5); // Version 2 } In both versions, Foo and callingMethod need to be changed, but in Version 2, Bar also needs to be changed. Can someone explain the advantage of having a wrapper/facade (with the exception of adapters or wrapping an external API or exposing an internal one).

  • Incorrect deployment of WSGI app to AWS using Elastic Beanstalk

    - by Dzmitry Zhaleznichenka
    cross-link to AWS forums I have developed a simple Python web service using WSGI and would like to deploy it to AWS cloud using Elastic Beanstalk. My problem is I cannot make all the options I specify in Elastic Beanstalk configuration to be correctly configured in the cloud. For deployment, I use Elastic Beanstalk CLI utility. I have run eb init command and set up the required parameters. After this, a directory named .elasticbeanstalk was created in my source tree. It has two config files that are used for deployment, namely config and optionsettings. The latter one among the other options contains the WSGI configuration that has to update /etc/httpd/conf.d/wsgi.conf at the instances. After some of my adjustments the file has the following settings: [aws:elasticbeanstalk:application:environment] DJANGO_SETTINGS_MODULE = PARAM1 = PARAM2 = PARAM4 = PARAM3 = PARAM5 = [aws:elasticbeanstalk:container:python] WSGIPath = handler.py NumProcesses = 2 StaticFiles = /static= NumThreads = 10 [aws:elasticbeanstalk:container:python:staticfiles] /static = static/ [aws:elasticbeanstalk:hostmanager] LogPublicationControl = false [aws:autoscaling:launchconfiguration] InstanceType = t1.micro EC2KeyName = zmicier-aws [aws:elasticbeanstalk:application] Application Healthcheck URL = [aws:autoscaling:asg] MaxSize = 10 MinSize = 1 Custom Availability Zones = [aws:elasticbeanstalk:monitoring] Automatically Terminate Unhealthy Instances = true [aws:elasticbeanstalk:sns:topics] Notification Endpoint = Notification Protocol = email It turns out that not all of these options are considered when I start the environment or update it. Thus, when I update NumThreads or NumProcesses, the respective parameters get changed in wsgi.conf as expected. But whatever I write to the WSGIPath and StaticFiles parameters, I'm not able to automatically change the respective values of wsgi.conf, they remain Alias /static /opt/python/current/app/ WSGIScriptAlias / /opt/python/current/app/application.py which drives me nuts. Moreover, when I deploy my application using git aws.push and having the following contents of .ebextensions/python.config file, neither of options I specify in it affects the deployment. option_settings: - namespace: aws:elasticbeanstalk:container:python option_name: WSGIPath value: mysite/wsgi.py - namespace: aws:elasticbeanstalk:container:python option_name: NumProcesses value: 5 - namespace: aws:elasticbeanstalk:container:python option_name: NumThreads value: 25 - namespace: aws:elasticbeanstalk:container:python:staticfiles option_name: /static/ value: app/static/ I wonder what I should do to force AWS use all the parameters I specify in the configuration, namely the WSGI Path and path to my static data.

  • Selenium/NUnit run one test on multiple IP addresses.

    - by Matt Clarkson
    I have a test suite DLL written in C# that uses Selenium.This is then loaded into NUnit and tests can be performed on our embedded web server boards. Does anyone know how to run a NUnit Selenium test on multiple IPs in multiple browsers? I have tried creating multiple DefaultSelenium classes but they point to the same Internet Explorer window. I need multiple instances of the Selenium RC controlling individual Internet Explorer windows. Have been looking a lot on the Selenium User Group and in various documentation but can find a definitive answer. Cheers, Matt

  • Can I use a serial port as TCP/IP interface on Red Hat Linux?

    - by ShaChris23
    Background We want to run an FTP server on a Red Hat Enterprise OS. The problem is, the machine we have does not have an Ethernet port/interface (please don't ask why; it's just a project requirement). We only have a serial port. Question Is there COTS / open source software that I can use to make serial port "look" like a an Ethernet port? My project is commercial. We run Red Hat Enterprise Linux 5.3. Note: Pardon me if my post title is unclear. If you can think of a better title, please suggest or simply change the title.

  • Java the little console game won't repeat?

    - by Jony Kale
    Okay, what I have so far is: You enter the game, and write "spin" to the console. Program will enter the while loop. In the while loop, if entered int is -1, return to the back (Set console input back to "", and let the user select what game he would like to play). Problem: Instead of going back, and selecting "spin" again, the program exits? Why is it happening? How can I fix this? private static Scanner console = new Scanner(System.in); private static Spin spin = new Spin(); private static String inputS = ""; private static int inputI = 0; private static String[] gamesArray = new String[] {"spin", "tof"}; private static boolean spinWheel = false; private static boolean tof = false; public static void main (String[] args) { if (inputS.equals("")) { System.out.println("Welcome to the system!"); System.out.print("Please select a game: "); inputS = console.nextLine(); } while (inputS.equals("spin")) { System.out.println("Welcome to the spin game! Please write 1 to spin. and -1 to exit back"); inputI = console.nextInt(); switch (inputI) { case 1: break; case -1: inputI = 0; inputS = ""; break; } } }

  • debian gateway using iptables

    - by meijuh
    I am having problems setting up a debian gateway server. My goal: Having eth1 the WAN interface. Having eth0 the LAN interface. Allow both ports 22 (SSH) and 80 (HTTP) accessed from the outside world on the gateway (SSH and HTTP run on this server). What I did was the following: Create a file /etc/iptables.rules with contents: /etc/iptables.rules: *nat -A POSTROUTING -o eth1 -j MASQUERADE COMMIT *filter -A INPUT -i lo -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -i eth1 -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -i eth1 -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -i eth1 -j DROP COMMIT edit /etc/network/interfaces as follows: /etc/network/interfaces: # The loopback network interface auto lo iface lo inet loopback pre-up iptables-restore < /etc/iptables.rules auto eth0 allow-hotplug eth0 iface eth0 inet dhcp #auto eth1 #allow-hotplug eth1 #iface eth1 inet dhcp allow-hotplug eth1 iface eth1 inet static address 217.119.224.51 netmask 255.255.255.248 gateway 217.119.224.49 dns-nameservers 217.119.226.67 217.119.226.68 Uncomment the rule net.ipv4.ip_forward=1 in /etc/sysctl.conf to allow packet forwarding. The static settings for eth1 such as the ip address I got from my router (which I want to replace); I simply copied these. I have a (windows) DNS + DHCP server on ip address 10.180.1.10, which assigns ip address 10.180.1.44 to eth0. What this server does is not really interesting it only maps domain names on our local network and assigns one static ip to the gateway. What works: on the gateway itself I can ping 8.8.8.8 and google.nl. So that is okey. What does not work: (1) Every machine connected to eth0 (indirectly via a switch) can not ping an ip or a domain. So I guess the gateway can not be found. (2) Also when I configure my linux machine (a laptop) to use a static ip 10.180.1.41, a mask and a gateway (10.180.1.44) I can not ping an ip or domain either. This means that maybe my iptables is incorrect of not loaded correctly. Or I maybe have to configure my DNS/DHCP on my windows machine. I have not reset the windows machine net, restart the DNS/DHCP services, should I do this? I did not install dnsmasq as desribed here: http://blog.noviantech.com/2010/12/22/debian-router-gateway-in-15-minutes/. I don't think this is necessary?

  • Using java.util.regex in Android apps - are there issues with this?

    - by johnrock
    In an Android app I have a utility class that I use to parse strings for 2 regEx's. I compile the 2 patterns in a static initializer so they only get compiled once, then activities can use the parsing methods statically. This works fine except that the first time the class is accessed and loaded, and the static initializer compiles the pattern, the UI hangs for close to a MINUTE while it compiles the pattern! After the first time, it flies on all subsequent calls to parseString(). My regEx that I am using is rather large - 847 characters, but in a normal java webapp this is lightning fast. I am testing this so far only in the emulator with a 1.5 AVD. Could this just be an emulator issue or is there some other reason that this pattern is taking so long to compile? private static final String exp1 = "(insertratherlong---847character--regexhere)"; private static Pattern regex1 = null; private static final String newLineAndTagsExp = "[<>\\s]"; private static Pattern regexNewLineAndTags = null; static { regex1 = Pattern.compile(exp1, Pattern.CASE_INSENSITIVE); regexNewLineAndTags = Pattern.compile(newLineAndTagsExp); } public static String parseString(CharSequence inputStr) { String replacementStr = "replaceMentText"; String resultString = "none"; try { Matcher regexMatcher = regex1.matcher(inputStr); try { resultString = regexMatcher.replaceAll(replacementStr); } catch (IllegalArgumentException ex) { } catch (IndexOutOfBoundsException ex) { } } catch (PatternSyntaxException ex) { } return resultString; }

  • Could a truly random number be generated using pings to psuedo-randomly selected IP addresses?

    - by _ande_turner_
    The question posed came about during a 2nd Year Comp Science lecture while discussing the impossibility of generating numbers in a deterministic computational device. This was the only suggestion which didn't depend on non-commodity-class hardware. Subsequently nobody would put their reputation on the line to argue definitively for or against it. Anyone care to make a stand for or against. If so, how about a mention as to a possible implementation?

    I have a table that contains the next columns: ip(varchar 255), index(bigint 20), time(timestamp) each time something is inserted there, the time column gets current timestamp. I want to run a query that returns all the rows that have been added in the last 24 hours. This is what I try to execute: SELECT ip, index FROM users WHERE ip = 'some ip' AND TIMESTAMPDIFF(HOURS,time,NOW()) < 24 And it doesn't work. Can someone help me out? Thanks :)

  • How to rate-limit concurrent sessions with nginx or haproxy?

    - by bantic
    I'm currently using nginx to reverse-proxy requests from web clients that are doing long-polling to an upstream. Since we're doing long polling (as opposed to websockets), when a client connects it will make multiple http connections to the server in serial, re-establishing a connection every time the server sends it some data (or timing out and re-establishing if the server has nothing to say for 10 seconds). What I'd like to do is limit the number of concurrent web clients. Since the clients are constantly making new HTTP requests instead of keeping a single request open, it's a little tricky to count the total number of web clients (because it's not the same as total number of concurrently connected http clients). The method I've come up with is to track http requests by the originating IP address, and store the IP address somewhere with a TTL of 20 seconds. If a request comes in whose IP isn't recognized, then we check the total number of unexpired stored IP addresses; if that's less than the maximum then we allow this request through. And if a request comes in with an IP address that we can find in the look-up table that hasn't yet expired, then it is allowed through as well. All requests that are allowed through have their IPs added to the table (if not there before) and the TTL refreshed to 20 seconds again. I had actually whipped something together that worked correctly this way using nginx along with the Redis 2.0 Nginx Module (and the nginx lua module to simplify the conditional branching), using redis to store my IP addresses with a TTL (the SETEX command), and checking the table size with the DBSIZE command. This worked but the performance was horrible. nginx and redis ended up using lots of cpu and the machine could only handle a very small number of concurrent requests. The new stick-table and tracking counters that were added to Haproxy in version 1.5 (via a commission from serverfault) seem like they might be ideal to implement exactly this sort of rate limiting, because the stick-table can track IP addresses and automatically expire entries. However, I don't see an easy way to get a total count of the unexpired entries in the stick table, which would be necessary to know the number of connected web clients. I'm curious if anyone has any suggestions, for nginx or haproxy or even for something else not mentioned here that I haven't thought of yet.

  • Java: creating objects of arrays with different names at runtime and accessing/updating them

    - by scriptingalias
    Hello, I'm trying to create a class that can instantiate arrays at runtime by giving each array a "name" created by the createtempobjectname() method. I'm having trouble making this program run. I would also like to see how I could access specific objects that were created during runtime and accessing those arrays by either changing value or accessing them. This is my mess so far, which compiles but gets a runtime exception. import java.lang.reflect.Array; public class arrays { private static String temp; public static int name = 0; public static Object o; public static Class c; public static void main(String... args) { assignobjectname(); //getclassname();//this is supposed to get the name of the object and somehow //allow the arrays to become updated using more code? } public static void getclassname() { String s = c.getName(); System.out.println(s); } public static void assignobjectname()//this creates the object by the name returned { //createtempobjectname() try { String object = createtempobjectname(); c = Class.forName(object); o = Array.newInstance(c, 20); } catch (ClassNotFoundException exception) { exception.printStackTrace(); } } public static String createtempobjectname() { name++; temp = Integer.toString(name); return temp; } }
