  • Please explain this Rails method to me like I'm a little kid.

    - by Senthil
    I found this in Ryan Bates' railscast site, but not sure how it works. #models/comment.rb def req=(request) self.user_ip = request.remote_ip self.user_agent = request.env['HTTP_USER_AGENT'] self.referrer = request.env['HTTP_REFERER'] end #blogs_controller.rb def create @blog = Blog.new(params[:blog]) @blog.req = request if @blog.save ... I see he is saving the user ip, user agent and referrer, but am confused with the req=(request) line. Any help is appreciated. Thanks

  • IPtables - Accept Arbitrary Packets

    - by Asad Moeen
    I've achieved a lot on blocking attacks on GameServers but I'm stuck on something. I've blocked major requests of game-server which it aceepts in the form "\xff\xff\xff\xff" which can be followed by the actual queries like get status or get info to make something like "\xff\xff\xff\xff getstatus " but I see other queries if sent to the game-server will cause it to reply with a "disconnect" packet with the same rate as input so if the input rate is high then the high output of "disconnect" might give lag to the server. Hence I want to block all queries except the ones actual clients use which I suppose are in the form "\xff\xff\xff\xff" or .... so, I tried using this rule : -A INPUT -p udp -m udp -m u32 ! --u32 0x1c=0xffffffff -j ACCEPT -A INPUT -p udp -m udp -m recent --set --name Total --rsource -A INPUT -p udp -m udp -m recent --update --seconds 1 --hitcount 20 --name Total --rsource -j DROP Now where the rule does accept the clients but it only blocks requests in the form "\xff\xff\xff\xff getstatus " ( by which GameServer replies with status ) and not just "getstatus " ( by which GameServer replies with disconnect packet ). So I suppose the accept rule is accepting the simple "string" as well. I actually want it to also block the non-(\xff) queries. So how do I modify the rule?

  • Local Apache Web server works only when connected to the net

    - by Jean
    Hello, I installed Ubunut and got the LAMP stack installed too. Now the problem is I have to be connected to the internet for the local apache webserver to work, else it does not. I changed the IP address on the dnshost, in the apache2.conf file, got the servername in the httpd.conf, which was empty. Any ideas guys. Thanks Jean

  • How do I identify Blackberry / OWA users in my IIS logs?

    - by Quinten
    We just rolled out a Blackberry Express Server, and would like to make sure that all Blackberry devices that our users own are connecting SOLELY through the BES server. We are running Exchange 2010 SP1. I've read some links that discuss blocking BIS at the firewall level. Before doing that, however, I'd like to individually contact all users with Blackberries and make sure that they have a chance to switch to the BES server. I've sent a company-wide email, but unsurprisingly folks tend to tune these out until they are forced into action. Is there an easy way to identify the users with Blackberries by searching IIS logs, or perhaps using the Exchange Management Shell? Especially some automated way? I've tried searching for the Blackberry identifier, but it does not appear next to any user name, so it's not as helpful as it could be. Edit: to clarify, what I'm talking about is the fact that Blackberries can use OWA to download mail to the phone. We do not allow IMAP or POP access through our firewall so that's not a concern--just folks with Blackberries using Blackberry's hack to allow it to connect to Exchange without a BES server. As far as I know, Blackberries are the only popular phones that use this method to download mail.

  • sendmail on Snow Leopard

    - by Jay
    I'm trying to get sendmail working on my MacBook Pro (OS 10.6.4), so that I can send mail with PHP's mail() function. If you know how to do this without sendmail, I'd be interested in that also. The plan is to send mail through smtp.gmail.com using my gmail account, unless you have a better idea. I did this and that didn't work. In /etc/postfix/smtp_sasl_passwords I tried both:     smtp.yourisp.com username:password and     smtp.yourisp.com [email protected]:password The problem seems to be that google doesn't like me. I don't think my ISP is blocking it because Mail.app can send email through smtp.gmail.com just fine. $email is my gmail address. $ printf "Subject: TestMail" | sendmail -f $email $email $ tail /var/log/mail.log Oct 21 19:38:18 Jays-MacBook-Pro postfix/master[8741]: daemon started -- version 2.5.5, configuration /etc/postfix Oct 21 19:38:18 Jays-MacBook-Pro postfix/qmgr[8743]: CAACBFA905: from=<$email>, size=377, nrcpt=1 (queue active) Oct 21 19:38:18 Jays-MacBook-Pro postfix/pickup[8742]: C2A68FA93A: uid=501 from=<$email> Oct 21 19:38:18 Jays-MacBook-Pro postfix/cleanup[8744]: C2A68FA93A: message-id=<20101021233818.$mydomain> Oct 21 19:38:18 Jays-MacBook-Pro postfix/qmgr[8743]: C2A68FA93A: from=<$email>, size=377, nrcpt=1 (queue active) Oct 21 19:38:18 Jays-MacBook-Pro postfix/smtp[8746]: initializing the client-side TLS engine Oct 21 19:38:18 Jays-MacBook-Pro postfix/smtp[8748]: initializing the client-side TLS engine Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8746]: connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8748]: connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8746]: CAACBFA905: to=<$email>, relay=none, delay=1334, delays=1304/0.04/30/0, dsn=4.4.1, status=deferred (connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out) Oct 21 19:38:49 Jays-MacBook-Pro postfix/smtp[8748]: C2A68FA93A: to=<$email>, relay=none, delay=30, delays=0.08/0.05/30/0, dsn=4.4.1, status=deferred (connect to smtp.gmail.com[74.125.157.109]:25: Operation timed out) $ I also tried setting myhostname, mydomain, and myorigin in /etc/postfix/main.cf to $ nslookup myip (as displayed by http://www.whatismyip.com/) And still no luck. Any ideas?

  • Motion detection in compressed domain (JPEG/Mpeg4/H264)

    - by paft
    everyone! I process video from IP cameras and have wrote a motion detection algorithm based on decompressed video analysis. But i really something more fast. I've found several papers about compressed domain analysis but have failed to find any implementations. Can anyone recommend me some code? found materials: http://www.ist-live.org/intranet/school-of-informatics-university-of-bradford001-7/41410206.pdf/view http://doc.rero.ch/lm.php?url=1000,43,4,20061128120121-NA/Bracamonte_Javier_-_A_Low_Complexity_Change_Detection_Algorithm_20061128.pdf

  • How to simulate a dial-up connection for testing purposes?

    - by mawg
    I have to code a server app where clients open a TCP/IP socket, send some data and close the connection. The data packets are small < 100 bytes, however there is talk of having them batch their transactions and send multiple packets. How can I best simulate a dial-up ut connection (using Delphy & Indy components, just FYI)? Is it as simple as open connection wait a while (what is the definition of "a while"?) close connection

  • error: unexplained error (code 130) at rsync.c(541) [sender=3.0.7]

    - by brazorf
    This error: unexplained error (code 130) at rsync.c(541) [sender=3.0.7] error is happening after i changed router. Actually, i found out that this error just happens on a ctrl+c signal, so it could be not representative about the error itself. The command i run is very basic: rsync -avz --delete /local/path/ username@host:/path/to/remote/directory Basically, the rsync just stuck there and nothing's happening, until i ctrl+c. After interrupting the process i got the error in subject. I past the whole thing here: rsync -avvvvz --delete /source/path/ username@host:/path/to/direectory cmd=<NULL> machine=HOSTNAME user=username path=/path/to/direectory cmd[0]=ssh cmd[1]=-l cmd[2]=username cmd[3]=HOSTNAME cmd[4]=rsync cmd[5]=--server cmd[6]=-vvvvlogDtprze.iLsf cmd[7]=--delete cmd[8]=. cmd[9]=/path/to/direectory opening connection using: ssh -l username HOSTNAME rsync --server -vvvvlogDtprze.iLsf --delete . /path/to/direectory note: iconv_open("UTF-8", "UTF-8") succeeded. ^C[sender] _exit_cleanup(code=20, file=rsync.c, line=541): entered rsync error: unexplained error (code 130) at rsync.c(541) [sender=3.0.7] [sender] _exit_cleanup(code=20, file=rsync.c, line=541): about to call exit(130) The authentication runs on ssh via rsa key. I tried basic troubleshoot such as: ping the remote host ssh -l username remote.host check software firewall logs i asked the remote host sysadmin to check for logs, and when i run that command a ssh connection is actually being established and i can state there is no comunication/authentication/name resolution issue here. Rolling back to old router make this work again. Both client and server are running ubuntu 10.04. Try to take a look at my router configuration, where i'm no experienced at all, but i didnt see any "suspect" (what i was looking for is firewall blocking something) setting. The router itself is DLINK DVA-G3670B. Any suggestion? Thank You F.

  • State server in webfarm scenario?

    - by Curtis White
    This is a fairly basic question about state server but assume there are 2 servers behind a load balancer. How do I configure the session state server? So, I have machine1 and machine2. I would assume that I would need to install the state server on 1 machine only and then use the internal IP to refer to that machine. Is this correct? As oppose too, I would not install state server on both machines.

  • Where can I find a good definition of a Software construct?

    - by Hugh
    I have scoured for 2 hours now across the internet, I have found courses with modules on software constructs but no clear definition only hints as to what one is. As far as I understand the definition it is an object that can be defined with a purpose for example a TCP/IP connection uses a Port which is a Software construct. Can anyone refer me to a full definition or give a more robust one?

  • closing MQ connection

    - by OakvilleWork
    Good afternoon, I wrote a project to Get Park Queue Info from the IBM MQ, it has producing an error when attempting to close the connection though. It is written in java. Under application in Event Viewer on the MQ machine it displays two errors. They are: “Channel program ended abnormally. Channel program ‘system.def.surconn’ ended abnormally. Look at previous error messages for channel program ‘system.def.surconn’ in the error files to determine the cause of the failure. The other message states: “Error on receive from host rnanaj (10.10.12.34) An error occurred receiving data from rnanaj (10.10.12.34) over tcp/ip. This may be due to a communications failure. The return code from tcp/ip recv() call was 10054 (X’2746’). Record these values.” This must be something how I try to connect or close the connection, below I have my code to connect and close, any ideas?? Connect: _logger.info("Start"); File outputFile = new File(System.getProperty("PROJECT_HOME"), "run/" + this.getClass().getSimpleName() + "." + System.getProperty("qmgr") + ".txt"); FileUtils.mkdirs(outputFile.getParentFile()); Connection jmsConn = null; Session jmsSession = null; QueueBrowser queueBrowser = null; BufferedWriter commandsBw = null; try { // get queue connection MQConnectionFactory MQConn = new MQConnectionFactory(); MQConn.setHostName(System.getProperty("host")); MQConn.setPort(Integer.valueOf(System.getProperty("port"))); MQConn.setQueueManager(System.getProperty("qmgr")); MQConn.setChannel("SYSTEM.DEF.SVRCONN"); MQConn.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP); jmsConn = (Connection) MQConn.createConnection(); jmsSession = jmsConn.createSession(false, Session.AUTO_ACKNOWLEDGE); Queue jmsQueue = jmsSession.createQueue("PARK"); // browse thru messages queueBrowser = jmsSession.createBrowser(jmsQueue); Enumeration msgEnum = queueBrowser.getEnumeration(); commandsBw = new BufferedWriter(new FileWriter(outputFile)); // String line = "DateTime\tMsgID\tOrigMsgID\tCorrelationID\tComputerName\tSubsystem\tDispatcherName\tProcessor\tJobID\tErrorMsg"; commandsBw.write(line); commandsBw.newLine(); while (msgEnum.hasMoreElements()) { Message message = (Message) msgEnum.nextElement(); line = dateFormatter.format(new Date(message.getJMSTimestamp())) + "\t" + message.getJMSMessageID() + "\t" + message.getStringProperty("pkd_orig_jms_msg_id") + "\t" + message.getJMSCorrelationID() + "\t" + message.getStringProperty("pkd_computer_name") + "\t" + message.getStringProperty("pkd_subsystem") + "\t" + message.getStringProperty("pkd_dispatcher_name") + "\t" + message.getStringProperty("pkd_processor") + "\t" + message.getStringProperty("pkd_job_id") + "\t" + message.getStringProperty("pkd_sysex_msg"); _logger.info(line); commandsBw.write(line); commandsBw.newLine(); } } Close: finally { IO.close(commandsBw); if (queueBrowser != null) { try { queueBrowser.close();} catch (Exception ignore) {}} if (jmsSession != null) { try { jmsSession.close();} catch (Exception ignore) {}} if (jmsConn != null) { try { jmsConn.stop();} catch (Exception ignore) {}} }
