  • dhcp configuration not working ubuntu 11.10

    - by Vivek Pradhan
    I am usually behind a proxy server in college so I connect to the ethernet or wifi using manual IPv4 addresses only inside college. I have been trying really hard to get the internet work at home, there is no proxy and I have set the network to use automatic dhcp. It seems like it is not able to connect to the port, It gets disconnected after some time automatically and then tries to reconnect. The same thing is happening with wifi networks also, after some time i see a pop up asking for authentication and ultimately its not able to connect. What might be the problem here. I looked up some similar questions and checked the /etc/network/interfaces file and looks like this: auto lo iface lo inet loopback I have no idea what those lines mean but there is no configuration for eth0 or wlan0. Any help is deeply appreciated. Ubuntu loses it charms due to these small glitches.

  • Proxied calls not working as expected

    - by AndyH
    I have been modifying an application to have a cleaner client/server split to allow for load splitting and resource sharing etc. Everything is written to an interface so it was easy to add a remoting layer to the interface using a proxy. Everything worked fine. The next phase was to add a caching layer to the interface and again this worked fine and speed was improved but not as much as I would have expected. On inspection it became very clear what was going on. I feel sure that this behavior has been seen many times before and there is probably a design pattern to solve the problem but it eludes me and I'm not even sure how to describe it. It is easiest explained with an example. Let's imagine the interface is interface IMyCode { List<IThing> getLots( List<String> ); IThing getOne( String id ); } The getLots() method calls getOne() and fills up the list before returning. The interface is implemented at the client which is proxied to a remoting client which then calls the remoting server which in turn calls the implementation at the server. At the client and the server layers there is also a cache. So we have :- Client interface | Client cache | Remote client | Remote server | Server cache | Server interface If we call getOne("A") at the client interface, the call is passed to the client cache which faults. This then calls the remote client which passes the call to the remote server. This then calls the server cache which also faults and so the call is eventually passed to the server interface which actually gets the IThing. In turn the server cache is filled and finally the client cache also. If getOne("A") is again called at the client interface the client cache has the data and it gets returned immediately. If a second client called getOne("B") it would fill the server cache with "B" as well as it's own client cache. Then, when the first client calls getOne("B") the client cache faults but the server cache has the data. This is all as one would expect and works well. Now lets call getLots( [ "C", "D" ] ). This works as you would expect by calling getOne() twice but there is a subtlety here. The call to getLots() cannot directly make use of the cache. Therefore the sequence is to call the client interface which in turn calls the remote client, then the remote server and eventually the server interface. This then calls getOne() to fill the list before returning. The problem is that the getOne() calls are being satisfied at the server when ideally they should be satisfied at the client. If you imagine that the client/server link is really slow then it becomes clear why the client call is more efficient than the server call once the client cache has the data. This example is contrived to illustrate the point. The more general problem is that you cannot just keep adding proxied layers to an interface and expect it to work as you would imagine. As soon as the call goes 'through' the proxy any subsequent calls are on the proxied side rather than 'self' side. Have I failed to learn or not learned something correctly? All this is implemented in Java and I haven't used EJBs. It seems that the example may be confusing. The problem is nothing to do with cache efficiencies. It is more to do with an illusion created by the use of proxies or AOP techniques in general. When you have an object whose class implements an interface there is an assumption that a call on that object might make further calls on that same object. For example, public String getInternalString() { return InetAddress.getLocalHost().toString(); } public String getString() { return getInternalString(); } If you get an object and call getString() the result depends where the code is running. If you add a remoting proxy to the class then the result could be different for calls to getString() and getInternalString() on the same object. This is because the initial call gets 'deproxied' before the actual method is called. I find this not only confusing but I wonder how I can control this behavior especially as the use of the proxy may be by a third party. The concept is fine but the practice is certainly not what I expected. Have I missed the point somewhere?

  • Using the mpz_powm functions from the GMP/MPIR libraries with negative exponents

    - by Mihai Todor
    Please consider the following code: mpz_t x, n, out; mpz_init_set_ui(x, 2UL); mpz_init_set_ui(n, 7UL); mpz_init(out); mpz_invert(out, x, n); gmp_printf ("%Zd\n", out);//prints 4. 2 * 4 (mod 7) = 1. OK mpz_powm_ui(out, x, -1UL, n);//prints 1. 2 * 1 (mod 7) = 2. How come? gmp_printf ("%Zd\n", out); mpz_clear(x); mpz_clear(n); mpz_clear(out); I am unable to understand how the mpz_powm functions handle negative exponents, although, according to the documentation, it is supposed to support them. I would expect that raising a number to -1 modulo n is equivalent to inverting it modulo n. What am I missing here?

  • What are block expressions actually good for?

    - by Helper Method
    I just solved the first problem from Project Euler in JavaFX for the fun of it and wondered what block expressions are actually good for? Why are they superior to functions? Is it the because of the narrowed scope? Less to write? Performance? Here's the Euler example. I used a block here but I don't know if it actually makes sense // sums up all number from low to high exclusive which are divisible by a or b function sumDivisibleBy(a: Integer, b: Integer, high: Integer) { def low = if (a <= b) a else b; def sum = { var result = 0; for (i in [low .. <high] where i mod 3 == 0 or i mod 5 == 0) { result += i } result } } Does a block makes sense here?

  • Data Source Security Part 4

    - by Steve Felts
    So far, I have covered Client Identity and Oracle Proxy Session features, with WLS or database credentials.  This article will cover one more feature, Identify-based pooling.  Then, there is one more topic to cover - how these options play with transactions.Identity-based Connection Pooling An identity based pool creates a heterogeneous pool of connections.  This allows applications to use a JDBC connection with a specific DBMS credential by pooling physical connections with different DBMS credentials.  The DBMS credential is based on either the WebLogic user mapped to a database user or the database user directly, based on the “use database credentials” setting as described earlier. Using this feature enabled with “use database credentials” enabled seems to be what is proposed in the JDBC standard, basically a heterogeneous pool with users specified by getConnection(user, password). The allocation of connections is more complex if Enable Identity Based Connection Pooling attribute is enabled on the data source.  When an application requests a database connection, the WebLogic Server instance selects an existing physical connection or creates a new physical connection with requested DBMS identity. The following section provides information on how heterogeneous connections are created:1. At connection pool initialization, the physical JDBC connections based on the configured or default “initial capacity” are created with the configured default DBMS credential of the data source.2. An application tries to get a connection from a data source.3a. If “use database credentials” is not enabled, the user specified in getConnection is mapped to a DBMS credential, as described earlier.  If the credential map doesn’t have a matching user, the default DBMS credential is used from the datasource descriptor.3b. If “use database credentials” is enabled, the user and password specified in getConnection are used directly.4. The connection pool is searched for a connection with a matching DBMS credential.5. If a match is found, the connection is reserved and returned to the application.6. If no match is found, a connection is created or reused based on the maximum capacity of the pool: - If the maximum capacity has not been reached, a new connection is created with the DBMS credential, reserved, and returned to the application.- If the pool has reached maximum capacity, based on the least recently used (LRU) algorithm, a physical connection is selected from the pool and destroyed. A new connection is created with the DBMS credential, reserved, and returned to the application. It should be clear that finding a matching connection is more expensive than a homogeneous pool.  Destroying a connection and getting a new one is very expensive.  If you can use a normal homogeneous pool or one of the light-weight options (client identity or an Oracle proxy connection), those should be used instead of identity based pooling. Regardless of how physical connections are created, each physical connection in the pool has its own DBMS credential information maintained by the pool. Once a physical connection is reserved by the pool, it does not change its DBMS credential even if the current thread changes its WebLogic user credential and continues to use the same connection. To configure this feature, select Enable Identity Based Connection Pooling.  See http://docs.oracle.com/cd/E24329_01/apirefs.1211/e24401/taskhelp/jdbc/jdbc_datasources/EnableIdentityBasedConnectionPooling.html  "Enable identity-based connection pooling for a JDBC data source" in Oracle WebLogic Server Administration Console Help. You must make the following changes to use Logging Last Resource (LLR) transaction optimization with Identity-based Pooling to get around the problem that multiple users will be accessing the associated transaction table.- You must configure a custom schema for LLR using a fully qualified LLR table name. All LLR connections will then use the named schema rather than the default schema when accessing the LLR transaction table.  - Use database specific administration tools to grant permission to access the named LLR table to all users that could access this table via a global transaction. By default, the LLR table is created during boot by the user configured for the connection in the data source. In most cases, the database will only allow access to this user and not allow access to mapped users. Connections within Transactions Now that we have covered the behavior of all of these various options, it’s time to discuss the exception to all of the rules.  When you get a connection within a transaction, it is associated with the transaction context on a particular WLS instance. When getting a connection with a data source configured with non-XA LLR or 1PC (using the JTS driver) with global transactions, the first connection obtained within the transaction is returned on subsequent connection requests regardless of the values of username/password specified and independent of the associated proxy user session, if any. The connection must be shared among all users of the connection when using LLR or 1PC. For XA data sources, the first connection obtained within the global transaction is returned on subsequent connection requests within the application server, regardless of the values of username/password specified and independent of the associated proxy user session, if any.  The connection must be shared among all users of the connection within a global transaction within the application server/JVM.

  • Ops Center and Oracle Solaris 11

    - by user12609425
    There have been a few questions about Ops Center and S11 recently. People have been trying to discover and update S11 from Enterprise Controllers installed on S10 or Linux, and running into problems, and wondering what the solution is. Well, the solution is that, if you want to be able to discover, monitor, and update S11 OSes, you need to install your Enterprise Controller and at least one Proxy Controller on S11 systems. The Oracle Solaris and Linux install guides both note this in the chapters that cover preparing your environment. Technically, if you have an S11 Proxy Controller you can at least discover, manage, and monitor S11 systems. However, features like the automated installer and the image packaging system (for OS updates) can only be used through Ops Center if your Enterprise Controller is installed on S11 as well.

  • is it possible that a greasemonkey script can work on one computer but not on another?

    - by plastic cloud
    i'm writing an greasemonkey script for somebody else. he is a moderator and i am not. and the script will help him do some moderating things. now the script works for me. as far as it can work for me.(as i am not a mod) but even those things that work for me are not working for him.. i checked his version of greasemonkey plugin and firefox and he is up to date. only thing that's really different is that i'm on a mac and he is pc, but i wouldn't think that would be any problem. this is one of the functions that is not working for him. he does gets the first and third GM_log message. but not the second one ("got some(1) .."). kmmh.trackNames = function(){ GM_log("starting to get names from the first "+kmmh.topAmount+" page(s) from leaderboard."); kmmh.leaderboardlist = []; for (var p=1; p<=(kmmh.topAmount); p++){ var page = "http://www.somegamesite.com/leaderboard?page="+ p; var boardHTML = ""; dojo.xhrGet({ url: page, sync: true, load: function(response){ boardHTML = response; GM_log("got some (1) => "+boardHTML.length); }, handleAs: "text" }); GM_log("got some (2) => "+boardHTML.length); //create dummy div and place leaderboard html in there var dummy = dojo.create('div', { innerHTML: boardHTML }); //search through it var searchN = dojo.query('.notcurrent', dummy).forEach(function(node,index){ if(index >= 10){ kmmh.leaderboardlist.push(node.textContent); // add names to array } }); } GM_log("all names from "+ kmmh.topAmount +" page(s) of leaderboard ==> "+ kmmh.leaderboardlist); does anyone have any idea what could be causing this ?? EDIT: i know i had to write according to what he would see on his mod screen. so i asked him to copy paste source of pages and so on. and besides that, this part of the script is not depending on being a mod or not. i got everything else working for him. just this function still doesn't on neither of his pc's.

  • lighttpd domains and url matching

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

  • VBA long overflow

    - by HK_CH
    Hi I am trying to do some maths with my VBA excel (prime factorization) and I am hitting the limit of the long data type (runtime error 6 Overflow). Is there any way to get around this and still stay within VBA? (I am aware that the obvious one would be to use another more appropriate programming language) Thanks for help in advance! Thank you, it works in so far that I am able to get the big numbers into the variables now. However when I try to apply the MOD function (bignumber MOD 2 for example) it still fails with error message runtime error 6 Overflow.

  • How do I dynamically import a module in App Engine?

    - by Scott Ferguson
    I'm trying to dynamically load a class from a specific module (called 'commands') and the code runs totally cool on my local setup running from a local Django server. This bombs out though when I deploy to Google App Engine. I've tried adding the commands module's parent module to the import as well with no avail (on either setup in that case). Here's the code: mod = __import__('commands.%s' % command, globals(), locals(), [command]) return getattr(mod, command) App Engine just throws an ImportError whenever it hits this. And the clarify, it doesn't bomb out on the commands module. If I have a command like 'commands.cat' it can't find 'cat'.

  • why Haskell can deduce [] type in this function

    - by Sili
    rho x = map (((flip mod) x).(\a -> a^2-1)) (rho x) This function will generate an infinite list. And I tested in GHCi, the function type is *Main> :t rho rho :: Integral b => b -> [b] If I define a function like this fun x = ((flip mod) x).(\a -> a^2-1) The type is *Main> :t fun fun :: Integral c => c -> c -> c My question is, how can Haskell deduce the function type to b - [b]? We don't have any [] type data in this function. Thanks!

  • Can't get MySQL to install

    - by James Marthenal
    I'd like to think I know what I'm doing in a Unix shell but maybe not. I made a mistake in a configuration file for MySQL, so I decided to just uninstall it and then reinstall it, so I did: sudo apt-get --purge remove mysql-server mysql-server-5.0 mysql-client The files were deleted, so I then tried to install it, but it didn't ask me for a root password or anything else, so I uninstalled it using the above command again and then did sudo rm -rf /etc/mysql sudo rm /etc/init.d/mysql sudo rm -rf /var/lib/mysql* I then restarted the computer then installed it again: sudo apt-get install mysql-server mysql-client It asked for a root password, and everything looked like it would work, until I saw this: $ sudo apt-get install mysql-server mysql-client Reading package lists...

  • Squid on an Azure VM

    - by LantisGaius
    I can't get it to work. Here's exactly what I did: Create a new Azure VM, Windows Server 2012. RDP to the new VM Download & Extract Squid for Windows (2.7.STABLE8) Rename the conf files (squid, mime & cachemgr) Add the following lines on the end of squid.conf auth_param basic program c:/squid/libexec/ncsa_auth.exe c:/squid/etc/passwd.txt auth_param basic children 5 auth_param basic realm Welcome to http://abcde.fg Squid Proxy! auth_param basic credentialsttl 12 hours auth_param basic casesensitive off acl ncsa_users proxy_auth REQUIRED http_access allow ncsa_users Use http://www.htaccesstools.com/htpasswd-generator-windows/ to create passwd.txt Test passwd.txt via c:/squid/libexec/ncsa_auth.exe c:/squid/etc/passwd.txt (success) squid -z squid -i net start squid (No errors so far). go to https://manage.windowsazure.com, Virtual Machines - myVM - Endpoints Add Endpoint: Name: Squid Protocol: TCP Public Port: 80 Private Port: 3128 That's it. Unfortunately, it doesn't work. I think I screwed something up at the endpoint? I'm not sure.. help? EDIT: I'm testing it via Firefox - Options - Advanced - Network, and the exact error is "The Proxy Server is refusing connections." I'm using my DNS as the Proxy server "abcdef.cloudapp.net" and port 80 (since that's my public endpoint).

  • Skype performance in IPSEC VPN

    - by dunxd
    I've been challenged to "improve Skype performance" for calls within my organisation. Having read the Skype IT Administrators Guide I am wondering whether we might have a performance issue where the Skype Clients in a call are all on our WAN. The call is initiated by a Skype Client at our head office, and terminated on a Skype Client in a remote office connected via IPSEC VPN. Where this happens, I assume the trafficfrom Client A (encrypted by Skype) goes to our ASA 5510, where it is furtehr encrypted, sent to the remote ASA 5505 decrypted, then passed to Client B which decrypts the Skype encryption. Would the call quality benefit if the traffic didn't go over the VPN, but instead only relied on Skype's encryption? I imagine I could achieve this by setting up a SOCKS5 proxy in our HQ DMZ for Skype traffic. Then the traffic goes from Client A to Proxy, over the Skype relay network, then arrives at Cisco ASA 5505 as any other internet traffic, and then to Client B. Is there likely to be any performance benefit in doing this? If so, is there a way to do it that doesn't require a proxy? Has anyone else tackled this?

  • Easiest way to allow direct HTTPS connection in Intercept mode?

    - by Nick Lin
    I know the SSL issue has been beaten to death I'm using DNS redirect to force my clients to use my intercept proxy. As we all know, intercepting HTTPS connection is not possible unless I provide a fake certificate. What I want to achieve here is to allow all HTTPS requests connect directly to the source server, thus bypassing Squid: HTTP connection Proxy by Squid HTTPS connection Bypass Squid and connect directly I spent the past few days goolging and trying different methods but none worked so far. I read about SSL tunneling using the CONNECT method but couldn't find any more information on it. I tried a similar method in using RINETD to forward all traffic going through port 443 of my Squid back to the original IP of www.pandora.com. Unfortunately, I did not realize all other HTTPS requests are also forwarded to the IP of www.pandora.com. For example, https://www.gmail.com also takes me to https://www.pandora.com Since I'm running the Intercept mode, the forwarding needs to be dynamic and match each HTTPS domain name with proper original IP. Can this be done in Squid or iptables? Lastly, I'm directing traffic to my Squid server using DNS zone redirect. For example, a client requests www.google.com, my DNS server directs that request to my Squid IP, then my transparent Squid will proxy that request. Will this set up affect what I'm trying to achieve? I tried many methods but couldn't get it to work. Any takes on how to do this?

  • How to upgrade Apache 2 from 2.2 to 2.4

    - by Nina
    I was in the process of doing a test upgrade from Apache 2.2 to 2.4.3. I'm using Ubuntu 10.04. I would have upgraded to 12.04 for this to see if the upgrade would go a lot smoother. Unfortunately, I was told it wasn't an option...so I'm stuck using 10.04. The process I did this was: Before attempting this, I have managed to upgrade APR from 1.3 to 1.4 as well since apache told me it was a requirement beforehand: http://apr.apache.org/download.cgi First remove all traces of the current apache: sudo apt-get --purge remove apache2 sudo apt-get remove apache2-common apache2-utils apache2.2-bin apache2-common sudo apt-get autoremove whereis apache2 sudo rm -Rf /etc/apache2 /usr/lib/apache2 /usr/include/apache2 Afterwards, I did the following: sudo apt-get install build-essential sudo apt-get build-dep apache2 Then install apache 2.4 with the following: wget http://apache.mirrors.tds.net//httpd/httpd-2.4.3.tar.gz tar -xzvf httpd-2.4.3.tar.gz && cd httpd-2.4.3 sudo ./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --enable-mods-shared=all --enable-deflate --enable-proxy --enable-proxy-balancer --enable-proxy-http --with-mpm=prefork sudo make sudo make install After the make install, I ended up getting a series of errors that prevented it from installing correctly: exports.c:2513: error: redefinition of 'ap_hack_apr_uid_current' exports.c:1838: note: previous definition of 'ap_hack_apr_uid_current' was here exports.c:2514: error: redefinition of 'ap_hack_apr_uid_name_get' exports.c:1839: note: previous definition of 'ap_hack_apr_uid_name_get' was here exports.c:2515: error: redefinition of 'ap_hack_apr_uid_get' exports.c:1840: note: previous definition of 'ap_hack_apr_uid_get' was here exports.c:2516: error: redefinition of 'ap_hack_apr_uid_homepath_get' Looking for exports.c only leads me back to the httpd-2.4.3 folder. So I'm not sure what these errors mean... Thanks in advance for any help you have to offer!

  • Setting up Squid -> VPN connection

    - by Nedlinin
    I recently purchased a VPS and am wanting to use it as a VPN server. However, it has bandwidth limitations. So, I figured since I already have a local Squid proxy caching things for me, I could have users connect to the proxy and the proxy connect to the VPN. Then when someone hits the web, Squid will serve it from cache if available and, if not, it will use the VPN to download it. My issue is, I have no idea how to set this up :p - Essentially I want Machine - Squid - VPN. My VPN is running on Ubuntu Server with pptpd. Squid is running on a local Arch Linux box. Squid and the VPN are both working perfectly independently. Any help on how to have Squid push traffic through the VPN would be greatly appreciated! Also: I don't actually want to use the VPN for all traffic. Otherwise, I'd just connect my router to the VPN and be happy. I only want to use it for web traffic from specific machines on the network.

  • Ruby on Rails (Redmine) on Apache - 503 Error

    - by andrewtweber
    I am running a Ruby on Rails application called Redmine. It's been working fine, but today it's giving a 503 Service Temporarily Unavailable error. (It was initially set up by an employee who is now gone.) I check the error log and it says: [Mon Nov 21 11:03:30 2011] [error] (111)Connection refused: proxy: HTTP: attempt to connect to 127.0.0.1:3000 (127.0.0.1) failed [Mon Nov 21 11:03:30 2011] [error] ap_proxy_connect_backend disabling worker for (127.0.0.1) Here's a chunk of my Apache config <VirtualHost *:80> ServerName redmine.{domain}.com RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://redminecluster%{REQUEST_URI} [P,QSA,L] </VirtualHost> <Proxy balancer://redminecluster> BalancerMember http://127.0.0.1:3000 </Proxy> I found this link: http://www.redmine.org/boards/2/topics/20561 which suggests I simply need to "start the redmine server." I've tried /etc/init.d/redmine start which gives me this output => Booting Mongrel => Rails 2.3.11 application starting on http://0.0.0.0:3000 The contents of /etc/init.d/redmine: cd /var/redmine sudo ruby script/server -d -e production One thing I immediately notice is that it says 0.0.0.0 instead of 127.0.0.1. In addition, running top or ps -ef shows no record of a "mongrel" or "redmine" process. I've also tried restarting Apache before and after starting redmine. Not sure where to go from here.
