  • Trying to build a dynamic PHP mysql_query string to update a row and getting back the updated row

    - by adardesign
    I have a form that jQuery tracks the onChage .change() event so when something is changed it runs a ajax request and i pass in the column, id, and the values in the url. Here i have the PHP code that should update the data. My question is now how do i build the mySQl string dynamically. and how do i echo back the changes/updates that where just changed on the db. Here is the PHP code i am trying to work with. <?php require_once('Connections/connect.php'); ?> <?php $id = $_GET['id']; $collumn = $_GET['collumn']; $val = $_GET['val']; ?> <?php mysql_select_db($myDB, $connection); // here i try to build the query string and pass in the passed in values $sqlUpdate = 'UPDATE `plProducts`.`allPens` SET `$collumn` = '$val' WHERE `allPens`.`prodId` = '$id' LIMIT 1;'; // here i want to echo back the updated row (or the updated data) $seeResults = mysql_query($sqlUpdate, $connection); echo $seeResults ?>

  • Need reasonably priced router with QoS support [closed]

    - by ULTRA_POROV
    I dont need wireless. I am expecting very heavy traffic, with possibly thousands of tcp connections open at one time. This would require that the router has good hardware. I also need to limit the different services i will provide. Lets say i need to guarantee 60% of all the bandwidth to HTTP, 10% FTP, and 10% for Mail... So the router software must have flexible QoS options as well. I don't know which one to chooose, because this information is usually not given on the router specs.

  • Iptable Rule to redirect all traffic requesting a specific domain

    - by user548971
    I'm on a simple linux proxy. I'd like to add iptable rules to drop all requests for a specific domain. I figured I run a dig command to get the ip addresses for the domain and then add an iptable rule for each one. It seems, however, that it doesn't work to bind to more than one ip address. So, it seems I need to add ip ranges like this... iptables -I FORWARD -p tcp -m iprange --dst-range 66.220.144.0-66.220.159.255 --dport 443 -j DROP That seems to work. However, it has proven pretty problematic to parse the output of dig and correctly create the appropriate iptable rules. Is there a better way? Thanks! EV

  • Windows Media Player 11 fails to authenticate with proxy (ISA)

    - by Ed Manet
    We have some users who need to use a 3rd party site that embeds Windows Media Player streaming video into a web page. Our users go through an ISA proxy server to connect to the Internet. The browser has no problems accessing the site through the proxy. When Media Player loads, we get prompted for network credentials, but the authentication fails. If we set up Internet Explorer 8 to not use the proxy, Media Player has no problem. Media Player is configured to use the RTSP/TCP and HTTP protocols, but not the RTSP/UDP protocol. Is this necessary? Is there a registry key I can use to enable it? Is this more of a proxy server issue? The proxy guy says it's a desktop issue.

  • Tool to automate basic connectivity testing

    - by feicipet
    After our vendors have setup a certain test environment, we need to go in to perform connectivity testing between PC to servers and also between servers. The problem is that we run a range of tests to telnet between 2 nodes on several ports and this is a manual and rather tedious process. Does anyone know of a small tool or script that I can take input on the range of ports to be test and will run an automated range of testing against those ports? All I need to do is to validate whether a TCP connection can be established from the source PC / server to the target server IP address / port. Thanks, Wong

  • Access to SQL Server 2005 from a non-domain machine using Windows authentication

    - by user304582
    Hi, I have a Windows domain within which a machine is running SQL Server 2005 and which is configured to support only Windows authentication. I would like to run a C# client application on a machine on the same network, but which is NOT on the domain, and access a database on the SQL Server 2005 instance. I thought that it would be a simple matter of doing something like this: string connectionString = "Data Source=server;Initial Catalog=database;User Id=domain\user;Password=password"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); However, this fails: the client-side error is: System.Data.SqlClient.SqlException: Login failed for user 'domain\user' and the server-side error is: Error 18456, Severity 14, State 5 I have tried various things including setting integrated security to true and false, and \ instead of \ in the User Id, but without success. In general, I know that it possible to connect to the SQL Server 2005 instance from a non-domain machine (for example, I am working with a Linux-based application which happily does this), but I don't seem to be able to work out how to do it from a Windows machine. Help would be appreciated! Thanks, Martin

  • Role of OSI layers when we open a url in browser?

    - by user2715898
    I have searched on this topic a lot but I am not able to understand how and where OSI layers (Application, Presentation, Session, Transport, Network, Datalink, Physical) come into picture in the whole process of opening a webpage in browser. I have read this - http://stackoverflow.com/questions/2092527/what-happens-when-you-type-in-a-url-in-browser?lq=1 and I know all the functions of all the layers that are there in OSI model. Also, do we use OSI model or TCP/IP in the whole process? Basically I am having problem linking all the things together. And please forgive me if there are resources out there that explain this concept. You can definitely point to them.

  • Make a PHP GET request from a PHP script and exit

    - by Abs
    Hello all, Is there something simpler than the following. I am trying to make a GET request to a PHP script and then exit the current script. I think this is a job for CURL but is there something simpler as I don't want to really worry about enabling the CURL php extension? In addition, will the below start the PHP script and then just come back and not wait for it to finish? //set GET variables $url = 'http://domain.com/get-post.php'; $fields = array( 'lname'=>urlencode($last_name), 'fname'=>urlencode($first_name) ); //url-ify the data for the GET foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } rtrim($fields_string,'&'); //open connection $ch = curl_init(); //set the url, number of POST vars, POST data curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_GET,count($fields)); curl_setopt($ch,CURLOPT_GETFIELDS,$fields_string); //execute GET $result = curl_exec($ch); //close connection curl_close($ch); I want to run the other script which contains functions when a condition is met so a simple include won't work as the if condition wraps around the functions, right? Please note, I am on windows machine and the code I am writing will only be used on a Windows OS. Thanks all for any help and advice

  • How can I redirect HTTP(S) traffic to another gateway?

    - by PsyStyle
    I have a network like 192.168.0.0/15 with the default gateway set to 192.168.0.1. All the workstations of the network use this gateway for all kind of accesses to the Internet. Now I am testing a new Internet connection with another provider and for that I'm using a second gateway on the same subnet with 192.168.0.2 as IP address. I want to redirect only HTTP and HTTPS traffic to this second gateway keeping untouched the address of the default gateway set inside every workstation. How can I accomplish this task? What I have to change inside the first's gateway firewall configuration or routes? I tried with a DNAT like: DNAT loc:192.168.0.1 loc:192.168.0.2 tcp 80 but nothing worked. I use Shorewall for simplicity in configuration but I can understand even theorical answers which I will try to adapt to my case.

  • How can I share Perl data structures through a socket?

    - by pavun_cool
    In sockets I have written the client server program. First I tried to send the normal string among them it sends fine. After that I tried to send the hash and array values from client to server and server to client. When I print the values using Dumper, it gives me only the reference value. What should I do to get the actual values in client server? Server Program: use IO::Socket; use strict; use warnings; my %hash = ( "name" => "pavunkumar " , "age" => 20 ) ; my $new = \%hash ; #Turn on System variable for Buffering output $| = 1; # Creating a a new socket my $socket= IO::Socket::INET->new(LocalPort=>5000,Proto=>'tcp',Localhost => 'localhost','Listen' => 5 , 'Reuse' => 1 ); die "could not create $! \n" unless ( $socket ); print "\nUDPServer Waiting port 5000\n"; my $new_sock = $socket->accept(); my $host = $new_sock->peerhost(); while(<$new_sock>) { #my $line = <$new_sock>; print Dumper "$host $_"; print $new_sock $new . "\n"; } print "$host is closed \n" ; Client Program use IO::Socket; use Data::Dumper ; use warnings ; use strict ; my %hash = ( "file" =>"log.txt" , size => "1000kb") ; my $ref = \%hash ; # This client for connecting the specified below address and port # INET function will create the socket file and establish the connection with # server my $port = shift || 5000 ; my $host = shift || 'localhost'; my $recv_data ; my $send_data; my $socket = new IO::Socket::INET ( PeerAddr => $host , PeerPort => $port , Proto => 'tcp', ) or die "Couldn't connect to Server\n"; while (1) { my $line = <stdin> ; print $socket $ref."\n"; if ( $line = <$socket> ) { print Dumper $line ; } else { print "Server is closed \n"; last ; } } I have given my sample program about what I am doing. Can any one tell me what I am doing wrong in this code? And what I need to do for accessing the hash values?

  • Socket send recv functions

    I have created a socket using the following lines of code. Now i change the value of the socket i get like this m_Socket++; Even now the send recv socket functions succeeds without throwing SOCKET_ERROR. I expect that it must throw error. Am i doing something wrong. struct sockaddr_in ServerSock; // Socket address structure to bind the Port Number to listen to char *localIP ; SOCKET SocServer; //To Set up the sockaddr structure ServerSock.sin_family = AF_INET; ServerSock.sin_addr.s_addr = INADDR_ANY; ServerSock.sin_port = htons(pLantronics->m_wRIPortNo); // To Create a socket for listening on wPortNumber if(( SocServer = socket( AF_INET, SOCK_STREAM, 0 )) == INVALID_SOCKET ) { return FALSE; } //To bind the socket with wPortNumber if(bind(SocServer,(sockaddr*)&ServerSock,sizeof(ServerSock))!=0) { return FALSE; } // To Listen for the connection on wPortNumber if(listen(SocServer,SOMAXCONN)!=0) { return FALSE; } // Structure to get the IP Address of the connecting Entity sockaddr_in insock; int insocklen=sizeof(insock); //To accept the Incoming connection on the wPortNumber pLantronics->m_Socket=accept(SocServer,(struct sockaddr*)&insock,&insocklen); if(pLantronics->m_Socket == INVALID_SOCKET) { shutdown(SocServer, 2 ); closesocket(SocServer ); return FALSE; } // To make socket non-blocking DWORD dwNonBlocking = 1; if(ioctlsocket( pLantronics->m_Socket, FIONBIO, &dwNonBlocking )) { shutdown(pLantronics->m_Socket, 2); closesocket(pLantronics->m_Socket); return FALSE; } pLantronics->m_sModemName = inet_ntoa(insock.sin_addr); Now i do m_Socket++;//change to some other number ideally expecting send recv to fail.

  • Best Approach for Checking and Inserting Records

    - by nevets1219
    In one of our existing C programs which purpose is: Open connection to DB for record in all_record: if record contain certain data: if record is NOT in table A: // see #1 insert record information into table A and B // see #2 Close connection to DB select field from table where field=XXX 2 inserts This is typically done every X months to sync everything up or so I'm told. I've also been told that this process takes roughly a couple of days. There is (currently) at most 2.5million records (though not necessarily all 2.5m will be inserted). One of the table contains 10 fields and the other 5 fields. There isn't much to be done about iterating through the records since that part can't be changed at the moment. What I would like to do is speed up the part where I query MySQL. I'm not sure if I have left out any important details -- please let me know! I'm also no SQL expert so feel free to point out the obvious. I thought about: Putting all the inserts into a transaction (at the moment I'm not sure how important it is for the transaction to be all-or-none or if this affects performance) Using Insert X Where Not Exists Y LOAD DATA INFILE (but that would require I create a (possibly) large temp file) I read that (hopefully someone can confirm) I should drop indexes so they aren't re-calculated. mysql Ver 14.7 Distrib 4.1.22, for sun-solaris2.10 (sparc) using readline 4.3

  • Python2.7: How can I speed up this bit of code (loop/lists/tuple optimization)?

    - by user89
    I repeat the following idiom again and again. I read from a large file (sometimes, up to 1.2 million records!) and store the output into an SQLite databse. Putting stuff into the SQLite DB seems to be fairly fast. def readerFunction(recordSize, recordFormat, connection, outputDirectory, outputFile, numObjects): insertString = "insert into NODE_DISP_INFO(node, analysis, timeStep, H1_translation, H2_translation, V_translation, H1_rotation, H2_rotation, V_rotation) values (?, ?, ?, ?, ?, ?, ?, ?, ?)" analysisNumber = int(outputPath[-3:]) outputFileObject = open(os.path.join(outputDirectory, outputFile), "rb") outputFileObject, numberOfRecordsInFileObject = determineNumberOfRecordsInFileObjectGivenRecordSize(recordSize, outputFileObject) numberOfRecordsPerObject = (numberOfRecordsInFileObject//numberOfObjects) loop1StartTime = time.time() for i in range(numberOfRecordsPerObject ): processedRecords = [] loop2StartTime = time.time() for j in range(numberOfObjects): fout = outputFileObject .read(recordSize) processedRecords.append(tuple([j+1, analysisNumber, i] + [x for x in list(struct.unpack(recordFormat, fout))])) loop2EndTime = time.time() print "Time taken to finish loop2: {}".format(loop2EndTime-loop2StartTime) dbInsertStartTime = time.time() connection.executemany(insertString, processedRecords) dbInsertEndTime = time.time() loop1EndTime = time.time() print "Time taken to finish loop1: {}".format(loop1EndTime-loop1StartTime) outputFileObject.close() print "Finished reading output file for analysis {}...".format(analysisNumber) When I run the code, it seems that "loop 2" and "inserting into the database" is where most execution time is spent. Average "loop 2" time is 0.003s, but it is run up to 50,000 times, in some analyses. The time spent putting stuff into the database is about the same: 0.004s. Currently, I am inserting into the database every time after loop2 finishes so that I don't have to deal with running out RAM. What could I do to speed up "loop 2"?

  • Trouble getting OS fingerprinting to work in iptables

    - by user1197457
    Everyone, As I understand it, OSF has been merged with the Kernel since 2.6.before-my-kernel-version. Yet when I do something like this: iptables -I INPUT -j ACCEPT -p tcp -m osf --genre Linux --log 0 --ttl 2 and I get an error like: iptables: No chain/target/match by that name iptables -L Shows no rules because I did an iptables -F at one point. ALSO, the following command: cat /proc/net/ip_tables_matches Does not show "osf" on the list. A google doesn't seem to help. I've also installed iptables-devel in hopes I'd be able to load the osf module. Sadly I haven't been able to get that to work. Centos 6.4 minimal Any guidance?

  • How to set the ActiveMQ redeliveryPolicy on a queue?

    - by edbras
    How do I set the redeliveryPolicy in ActiveMQ on a Queue? 1) In the doc, see: activeMQ Redelivery, the explain that you should set it on the ConnectionFactory or Connection. But I want to use different value's for different Queue's. 2) Apart from that, I don't seem to get it work. Setting it on the connection factory in Spring (I am using activemq 5.4.2. with Spring 3.0) like this don't seem to have any effect: <amq:connectionFactory id="amqConnectionFactory" brokerURL="${jms.factory.url}" > <amq:properties> <amq:redeliveryPolicy maximumRedeliveries="6" initialRedeliveryDelay="15000" useExponentialBackOff="true" backOffMultiplier="5"/> </amq:properties> </amq:connectionFactory> I also tried to set it as property on the defined Queue, but that also seem to be ignored as the redelivery occurs sooner that the defined values: <amq:queue id="jmsQueueDeclarationSnd" physicalName="${jms.queue.declaration.snd}" > <amq:properties> <amq:redeliveryPolicy maximumRedeliveries="6" initialRedeliveryDelay="15000" useExponentialBackOff="true" backOffMultiplier="5"/> </amq:properties> </amq:queue> Thanks

  • How can I get 100% test coverage in a Perl module that uses DBI?

    - by BrianH
    I am a bit new to the Devel::Cover module, but have found it very useful in making sure I am not missing tests. A problem I am running into is understanding the report from Devel::Cover. I've looked at the documentation, but can't figure out what I need to test to get 100% coverage. Here is the output from the cover report: line err stmt bran cond sub pod time code ... 36 sub connect_database { 37 3 3 1 1126 my $self = shift; 38 3 100 24 if ( !$self->{dsn} ) { 39 1 7 croak 'dsn not supplied - cannot connect'; 40 } 41 *** 2 33 21 $self->{dbh} = DBI->connect( $self->{dsn}, q{}, q{} ) 42 || croak "$DBI::errstr"; 43 1 11 return $self; 44 } ... line err % l !l&&r !l&&!r expr ----- --- ------ ------ ------ ------ ---- 41 *** 33 1 0 0 'DBI'->connect($$self{'dsn'}, '', '') || croak("$DBI::errstr") And here is and example of my code that tests this specific line: my $database = MyModule::Database->new( { dsn => 'Invalid DSN' }); throws_ok( sub { $database->connect_database() }, qr/Can't connect to data source/, 'Test connection exception (invalid dsn)' ); This test passes - the connect does throw an error and fulfills my "throws_ok" test. I do have some tests that test for a successful connection, which is why I think I have 33% coverage, but if I'm reading it correctly, cover thinks I am not testing the "|| croak" part of the statement. I thought I was, with the "throws_ok" test, but obviously I am missing something. Does anyone have advice on how I can test my DBI-connect line successfully? Thanks!

    I have a web page that when I run it on a remote computer I get the message saying that remote errors cannot be viewed When I go to view it on my web server machine, I get a message saying: Internet Explorer cannot display the webpage • Most likely causes: • You are not connected to the Internet. • The website is encountering problems. • There might be a typing error in the address. What you can try: Check your Internet connection. Try visiting another website to make sure you are connected. Retype the address. Go back to the previous page. I can get to google fine, so it is not the internet connection.... But this message gives me nothing to work on. How can I get more info as to why my page is not working?

  • How to force a drop of MSSQL Server database

    - by ng01
    I am trying to delete an MSSQL Server database, however I am having no luck. I have tried multiple things such as user ALTER DATABASE my_database SET RESTRICTED_USER WITH ROLLBACK IMMEDIATE; GO DROP DATABASE my_database; GO I have also tried to right click on it a delete it. This does not work, it tells me "Cannot drop database "ima_debts" because it is currently in use". The thing is there is definately no other user connected to it. In fact I disabled TCP/IP for the database and restarted it. Not even "Microsoft SQL Server Management Studio (Administrator)" is connected to it. I have made sure to login to "master". Why is it telling me it is currently in use. Is it possible for me to delete perhaps a directory or something from the file system to get rid of this database? Any help would be appreciated. Thanks.

  • I missed allowing ".NET Runtime Optimization Service" while installing a game — could there be any problems?

    - by MDLss
    I'm using ESET Smart Security 4 on Windows 7. I selected Interactive Mode so it asks me when something needs to connect to my PC. So when I was installing a game named League of Legends, I was away from my computer. When I came back, I saw that the download was finished but ESET was asking whether to allow .NET Runtime Optimization Service to connect my computer using port 80 TCP. So I selected Allow but It was too late because the download was already finished. I can play the game, but could it be bugged or broken or something?

  • Server seems up, but accepts no connections whatsoever

    - by Rnatau
    Hi, I have a problem with a Debian based Server, unfortunately housed in a remote location. Two days ago, it was suddenly down and completely unreachable. After having someone reboot it, it worked for about a day, then seemed to be down again. This time, however, it was different: -The server reacts to pings -It is scannable, and all the relevant ports are open But: -Open shells were immediately blocked, and no warning had been shown -It's not possible to open any connection - the TCP/IP handshake seems to have some problems: SSH handshake As this is a private server of a small community, we don't have the resources to pay a technician to fix the problem for us, so any hints how to fix the problem after the next reboot would be highly appreciated... Thanks a lot!
