• Automatically change div on mouseover and on timer

  - by IrishSaffa

  I'm a bit o a noob so any help would be great... What I need to do is have it so that the div associated to a specific li can change on hover as well as automatically change on a timer so that it scrolls through the option. here is my code: <script type="text/javascript"> $(function () { $("#switches li").mouseover(function () { var $this = $(this); $("#slides div").hide(); $("#slide" + $this.attr("id").replace(/switch/, "")).show(); }); }); </script> <div id="featured"> <ul id="switches"> <li id="switch1"><a href="activity_spa.html">Spa &amp; Wellness</a></li> <li id="switch2"><a href="#">Gala Venues</a></li> <li id="switch3"><a href="#">Dining</a></li> <li id="switch4"><a href="#">Shopping</a></li> <li id="switch5"><a href="#">Golf</a></li> <li id="switch6"><a href="#">Team Building</a></li> <li id="switch7"><a href="#">Equestrian</a></li> </ul> <div id="slides"> <div id="slide1"><img src="images/image2.jpg" alt="" /></div> <div id="slide2" style="display:none;"><img src="images/image6.jpg" alt="" /></div> <div id="slide3" style="display:none;"><img src="images/image1.jpg" alt="" /></div> <div id="slide4" style="display:none;"><img src="images/image3.jpg" alt="" /></div> <div id="slide5" style="display:none;"><img src="images/image5.jpg" alt="" /></div> <div id="slide6" style="display:none;"><img src="images/image7.jpg" alt="" /></div> <div id="slide7" style="display:none;"><img src="images/image4.jpg" alt="" /></div> </div> </div>

• click handler after using Ajax

  - by Tom

  I have a site that plays a stream. I perform an AJAX call to the server once a person presses a button. <input type="submit" class="play" data-type="<?php echo $result_cameras[$i]["camera_type"]; ?>" data-hash="<?php echo $result_cameras[$i]["camera_hash"]; ?>" value="<?php echo $result_cameras[$i]["camera_name"]; ?>"> This prints out a bunch of buttons that the user can select. This is processed by the following code: <script> $(document).ready(function(){ $(".play").click(function(){ var camerahash = $(this).data('hash'); var cameratype = $(this).data('type'); function doAjax(){ $.ajax({ url: 'index.php?option=streaming&task=playstream&id_hash=<?php echo $id_hash; ?>&camera_hash='+camerahash+'&format=raw', success: function(data) { if (data == 'Initializing...please wait') { $('#quote p').html(data); setTimeout(doAjax, 2000); } else { if (cameratype == "WEBCAM" && data == 'Stream is ready...') { $('#quote p').html(data); window.location = 'rtsp://<?php echo DEVSTREAMWEB; ?>/<?php echo $session_id;?>/'+camerahash; } else if (cameratype == "AXIS" && data == 'Stream is ready...') { $('#quote p').html(data); window.location = 'rtsp://<?php echo DEVSTREAMIP; ?>/<?php echo $session_id;?>/'+camerahash; } else { $('#quote p').html(data); } } } }); } doAjax(); }); }); </script> The server returns the messages such as Stream is ready.... My problem is that everything is working great except on additional button clicks. Specifically when they get success (video plays) and they exit back out, they don't get any other messages if they click another button. It is as if the click event is not triggered. Do I need to be doing something to the click handler to respond?

• How do I defer execution of some Ruby code until later and run it on demand in this scenario?

  - by Kyle Kaitan

  I've got some code that looks like the following. First, there's a simple Parser class for parsing command-line arguments with options. class Parser def initialize(&b); ...; end # Create new parser. def parse(args = ARGV); ...; end # Consume command-line args. def opt(...); ...; end # Declare supported option. def die(...); ...; end # Validation handler. end Then I have my own Parsers module which holds some metadata about parsers that I want to track. module Parsers ParserMap = {} def self.make_parser(kind, desc, &b) b ||= lambda {} module_eval { ParserMap[kind] = {:desc => "", :validation => lambda {} } ParserMap[kind][:desc] = desc # Create new parser identified by `<Kind>Parser`. Making a Parser is very # expensive, so we defer its creation until it's actually needed later # by wrapping it in a lambda and calling it when we actually need it. const_set(name_for_parser(kind), lambda { Parser.new(&b) }) } end # ... end Now when you want to add a new parser, you can call make_parser like so: make_parser :db, "login to database" do # Options that this parser knows how to parse. opt :verbose, "be verbose with output messages" opt :uid, "user id" opt :pwd, "password" end Cool. But there's a problem. We want to optionally associate validation with each parser, so that we can write something like: validation = lambda { |parser, opts| parser.die unless opts[:uid] && opts[:pwd] # Must provide login. } The interface contract with Parser says that we can't do any validation until after Parser#parse has been called. So, we want to do the following: Associate an optional block with every Parser we make with make_parser. We also want to be able to run this block, ideally as a new method called Parser#validate. But any on-demand method is equally suitable. How do we do that?

• Displaying individual elements of an object in an Arraylist through a for loop?

  - by user1180888

  I'm trying to Display individual elements of an Object I have created. It is a simple Java program that allows users to add and keep track of Player Details. I'm just stumped when it comes to displaying the details after they have been added already. here is what my code looks like I can create the object and input it into the arraylist no problem using the case 2, but when I try to print it out I want to do something like System.out.println("Player Name" + myPlayersArrayList.PlayerName + "Player Position" + myPlayerArrayList.PlayerPosition + "Player Age" + "Player Age"); I know that is not correct, but I dont really know what to do, if anyone can be of any help it would be greatly appreciated. Thanks System.out.println("Welcome to the Football Player database"); System.out.print(System.getProperty("line.separator")); UserInput myFirstUserInput = new UserInput(); int selection; ArrayList<Player> myPlayersArrayList = new ArrayList<Player>(); while (true) { System.out.println("1. View The Players"); System.out.println("2. Add A Player"); System.out.println("3. Edit A Player"); System.out.println("4. Delete A Player"); System.out.println("5. Exit ") ; System.out.print(System.getProperty("line.separator")); selection = myFirstUserInput.getInt("Please select an option"); System.out.print(System.getProperty("line.separator")); switch(selection){ case 1: if (myPlayersArrayList.isEmpty()) { System.out.println("No Players Have Been Entered Yet"); System.out.print(System.getProperty("line.separator")); break;} else {for(int i = 0; i < myPlayersArrayList.size(); i++){ System.out.println(myPlayersArrayList); } break; case 2: { String playerName,playerPos; int playerAge; playerName = (myFirstUserInput.getString("Enter Player name")); playerPos = (myFirstUserInput.getString("Enter Player Position")); playerAge = (myFirstUserInput.getInt("Enter Player Age")); myPlayersArrayList.add(new Player(playerName, playerPos, playerAge)); ; break; }

• Is there a way to apply a CSS class from within a style?

  - by zashu

  I'm trying to be more modular in my CSS style sheets and was wondering if there is some feature like an include or apply that allows the author to apply a set of styles dynamically. Since I am having a hard time wording the question, perhaps an example will make more sense. Let's say, for example, I have the following CSS: .red {color:#e00b0b} #footer a {font-size:0.8em} h2 {font-size:1.4em; font-weight:bold;} In my page, let's say that I want both the footer links and h2 elements to use the special red color (there may be other locations I would like to use it as well). Ideally, I would like to do something like the following: .red {color:#e00b0b} #footer a {font-size:0.8em; apply-class:".red";} h2 {font-size:1.4em; font-weight:bold; apply-class:".red";} To me, this feels "modular" in a way because I can make modifications to the .red class without having to worry so much about where it is used, and other locations can use the styles in that class without worrying about, specifically, what they are. I understand that I have the following options and have included why, in my fairly inexperienced opinion, they are less-than-perfect: Add the color property to every element I want to be that color. Not ideal because, if I change the color, I have to update every rule to match the new color. Add the red class to every element I want to be red. Not ideal because it means that my HTML is dictating presentation. Create an additional rule that selects every element I want to be red and apply the color property to that. Not ideal because it is harder to find all of the rules that style a specific element, making maintenance more of a challenge Maybe I'm just being an ass and the following options are the only options and I should stick with them. I'm wondering, however, if the "ideal" (well, my ideal) method exists and, if so, what is the proper syntax? If it doesn't exist, option 3 above seems like my best bet. However, I would like to get confirmation.

• Apache 2.2 and FastCGI stops responding, warnings, crashes

  - by Brett

  I've seen this question posted a few times using a Google search, with no real answers. I have a multi-threaded FastCGI application running with Apache 2.2 on FreeBSD 7.2. There are a few issues with it, and I am unable to really figure out the source of the problem even after poking through a bunch of the mod_fastcgi source code. My FastCGI application gets anywhere from 2 to 15 or so hits per second, and mostly services a back-end API (the majority of web server usage is for this, and not actually serving content). Everything seems to work ok under normal conditions, but recently this problem has been becoming worse. It starts out with the FastCGI process manager apparently trying to close unneeded processes, sending them a SIGTERM signal. I catch the signal, clean up some stuff, and exit (by calling exit()) with status code 0. This process seems to result in three log messages in my httpd error log: [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" (pid 98182) termination signaled [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" (pid 98182) terminated by calling exit with status '0' [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" restarted (pid 98294) I am not sure why it says it is restarting the process, but in any case no core dump is ever generated so I do believe it is the FastCGI process manager doing it's thing. This makes sense because it begins to happen after the initial load increase from restarting Apache. Since it's down for a few seconds, it gets hit with a couple of hundred requests over the first few seconds it's running again (sometimes even hitting the upper limit of MAXCLIENTS in Apache), and this seems to be the process manager doing the work of spawning more processes to handle the increased load. So this all seems fine, but here is where things get weird. There are really two problems that I see. First, my multithreaded FastCGI process spawns 25 worker threads, and all seem to be used according to my internal log files (multiple processes are clearly using multiple threads to do work). However it seems that 3 or 4 FastCGI processes is not enough to handle the 5 to 15 hit per second load, even though the requests take about .02s or so to process internally. In order to be at all responsive, it seems I need 50 or more FastCGI processes, leading me to believe that FastCGI does not realize that my program is multithreaded. I've read the documentation at http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html and do not see any option pertaining to multithreaded-ness, and my internal code is more or less set up just like the examples provided by the FastCGI library. The second problem I am having is that once process termination has happened a bunch of times as above (and seemingly at random), I begin getting a lot of these messages in my error log: [Tue Jun 01 14:06:22 2010] [warn] (32)Broken pipe: FastCGI: write() to PM failed (ignore if a restart or shutdown is pending) The messages occur for about half the hits I get to the server, and it completely kills the responsiveness of my application - it seems FastCGI will look for a working "pipe" until it finds one, and fail to realize that whatever application it is trying to contact is dead. It does still work though, it's just incredibly unresponsive - sometimes taking up to 40 or so seconds to process a request. I recompiled mod_fastcgi with some extra debugging around the point of the error message, and it appears that the error happens when it tries to write() to the application. The call to write() fails with a -1 return code, and sets errno to EPIPE. I am noticing that the issue happens mostly when either a crash occurs in one of the FastCGI processes, or a bunch of them are seemingly terminated by the process manager. I haven't had any core dumps though, except for one, where the backtrace outputted by gdb is just a single call to free() at address 0x0000000000000000 with nothing else in the stack trace, so I don't really know what to make of that. I'm thinking it happens sometime after the SIGTERM signal is caught, maybe some global variable not being cleaned up properly or something.

• How do I install PyYAML into local install of Python?

  - by Daryl Spitzer

  I've installed Python 2.6.4 into (a subdirectory in) my home directory on a Linux machine with Python 2.3.4 pre-installed, because I need to run some code that I've decided would require too much work to make it run on 2.3.4. (I'm not on the sudoers list for that machine.) I was hoping I could run ~/Python-2.6.4/python setup.py install (from the PyYAML directory in my home directory, where I untarred the PyYAML sources) and it would be smart enough to install it into my local Python 2.6.4 install. But it's not. (See the P.S.) Is it possible to install PyYAML into my local Python install, so that "import yaml" will work when I invoke that Python? If so, how do I do that? P.S. Here's the output when I ran ~/Python-2.6.4/python setup.py install: running install running build running build_py creating build/lib.linux-ppc64-2.6 creating build/lib.linux-ppc64-2.6/yaml copying lib/yaml/composer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/nodes.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/dumper.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/resolver.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/events.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/emitter.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/error.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/loader.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/cyaml.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/scanner.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/__init__.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/serializer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/reader.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/representer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/constructor.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/tokens.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/parser.py -> build/lib.linux-ppc64-2.6/yaml running build_ext creating build/temp.linux-ppc64-2.6 checking if libyaml is compilable gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/home/dspitzer/Python-2.6.4/Include -I/home/dspitzer/Python-2.6.4 -c build/temp.linux-ppc64-2.6/check_libyaml.c -o build/temp.linux-ppc64-2.6/check_libyaml.o build/temp.linux-ppc64-2.6/check_libyaml.c:2:18: yaml.h: No such file or directory build/temp.linux-ppc64-2.6/check_libyaml.c: In function `main': build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: `yaml_parser_t' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: (Each undeclared identifier is reported only once build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: for each function it appears in.) build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: syntax error before "parser" build/temp.linux-ppc64-2.6/check_libyaml.c:6: error: `yaml_emitter_t' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:8: warning: implicit declaration of function `yaml_parser_initialize' build/temp.linux-ppc64-2.6/check_libyaml.c:8: error: `parser' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:9: warning: implicit declaration of function `yaml_parser_delete' build/temp.linux-ppc64-2.6/check_libyaml.c:11: warning: implicit declaration of function `yaml_emitter_initialize' build/temp.linux-ppc64-2.6/check_libyaml.c:11: error: `emitter' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:12: warning: implicit declaration of function `yaml_emitter_delete' libyaml is not found or a compiler error: forcing --without-libyaml (if libyaml is installed correctly, you may need to specify the option --include-dirs or uncomment and modify the parameter include_dirs in setup.cfg) running install_lib creating /usr/local/lib/python2.6 error: could not create '/usr/local/lib/python2.6': Permission denied

• multiple puppet masters

  - by Oli

  I would like to set up an additional puppet master but have the CA server handled by only 1 puppet master. I have set this up as per the documentation here: http://docs.puppetlabs.com/guides/scaling_multiple_masters.html I have configured my second puppet master as follows: [main] ... ca = false ca_server = puppet-master1.test.net I am using passenger so I am a bit confused how the virtual-host.conf file should look for my second puppet-master2.test.net. Here is mine (updated as per Shane Maddens answer): LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18 PassengerRuby /usr/bin/ruby Listen 8140 <VirtualHost *:8140> ProxyPassMatch ^/([^/]+/certificate.*)$ https://puppet-master1.test.net:8140/$1 SSLEngine on SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP SSLCertificateFile /var/lib/puppet/ssl/certs/puppet-master2.test.net.pem SSLCertificateKeyFile /var/lib/puppet/ssl/private_keys/puppet-master2.test.net.pem #SSLCertificateChainFile /var/lib/puppet/ssl/ca/ca_crt.pem #SSLCACertificateFile /var/lib/puppet/ssl/ca/ca_crt.pem # If Apache complains about invalid signatures on the CRL, you can try disabling # CRL checking by commenting the next line, but this is not recommended. #SSLCARevocationFile /var/lib/puppet/ssl/ca/ca_crl.pem SSLVerifyClient optional SSLVerifyDepth 1 # The `ExportCertData` option is needed for agent certificate expiration warnings SSLOptions +StdEnvVars +ExportCertData # This header needs to be set if using a loadbalancer or proxy RequestHeader unset X-Forwarded-For RequestHeader set X-SSL-Subject %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-DN %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-Verify %{SSL_CLIENT_VERIFY}e DocumentRoot /etc/puppet/rack/public/ RackBaseURI / <Directory /etc/puppet/rack/> Options None AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> I have commented out the #SSLCertificateChainFile, #SSLCACertificateFile & #SSLCARevocationFile - this is not a CA server so not sure I need this. How would I get passenger to work with these? I would like to use ProxyPassMatch which I have configured as per the documentation. I don't want to specify a ca server in every puppet.conf file. I am getting this error when trying to get create a cert from a puppet client pointing to the second puppet master server (puppet-master2.test.net): [root@puppet-client2 ~]# puppet agent --test Error: Could not request certificate: Could not intern from s: nested asn1 error Exiting; failed to retrieve certificate and waitforcert is disabled On the puppet client I have this [main] server = puppet-master2.test.net What have I missed? -- update Here is a new virtual host file on my secondary puppet master.

• PHP crashing (seg-fault) under mod_fcgi, apache

  - by Andras Gyomrey

  I've been programming a site using: Zend Framework 1.11.5 (complete MVC) PHP 5.3.6 Apache 2.2.19 CentOS 5.6 i686 virtuozzo on vps cPanel WHM 11.30.1 (build 4) Mysql 5.1.56-log Mysqli API 5.1.56 The issue started here http://stackoverflow.com/questions/6769515/php-programming-seg-fault. In brief, php is giving me random segmentation-faults. [Wed Jul 20 17:45:34 2011] [error] mod_fcgid: process /usr/local/cpanel/cgi-sys/php5(11562) exit(communication error), get unexpected signal 11 [Wed Jul 20 17:45:34 2011] [warn] [client 190.78.208.30] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server [Wed Jul 20 17:45:34 2011] [error] [client 190.78.208.30] Premature end of script headers: index.php About extensions. When i compile php with "--enable-debug" flag, i have to disable this line: zend_extension="/usr/local/IonCube/ioncube_loader_lin_5.3.so" Otherwise, the server doesn't accept requests and i get a "The connection with the server was reset". It is possible that i have to disable eaccelerator too because of the same reason. I still don't get why apache gets running it some times and some others not: extension="eaccelerator.so" Anyway, after i get httpd running, seg-faults can occurr randomly. If i don't compile php with "--enable-debug" flag, i can get DETERMINISTICALLY a php crash: <?php class Admin_DbController extends Controller_BaseController { public function updateSqlDefinitionsAction() { $db = Zend_Registry::get('db'); $row = $db->fetchRow("SHOW CREATE TABLE 222AFI"); } } ?> BUT if i compile php with "--enable-debug" flag, it's really hard to get this error. I must add some complexity to make it crash. I have to be doing many paralell requests for a few seconds to get a crash: <?php class Admin_DbController extends Controller_BaseController { public function updateSqlDefinitionsAction() { $db = Zend_Registry::get('db'); $tableList = $db->listTables(); foreach ($tableList as $tableName){ $row = $db->fetchRow("SHOW CREATE TABLE " . $db->quoteIdentifier($tableName)); file_put_contents( DB_DEFINITIONS_PATH . '/' . $tableName . '.sql', $row['Create Table'] . ';' ); } } } ?> Please notice this is the same script, but creating DDL for all tables in database rather than for one. It seems that if php is heavy loaded (with extensions and me doing many paralell requests) it's when i get php to crash. About starting httpd with "-X": i've tried. The thing is, it is already hard to make php crash with --enable-debug. With "-X" option (which only enables one child process) i can't do parallel requests. So i haven't been able to create to proper debug backtrace: https://bugs.php.net/bugs-generating-backtrace.php My concrete question is, what do i do to get a coredump? root@GWT4 [~]# httpd -V Server version: Apache/2.2.19 (Unix) Server built: Jul 20 2011 19:18:58 Cpanel::Easy::Apache v3.4.2 rev9999 Server's Module Magic Number: 20051115:28 Server loaded: APR 1.4.5, APR-Util 1.3.12 Compiled using: APR 1.4.5, APR-Util 1.3.12 Architecture: 32-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/usr/local/apache" -D SUEXEC_BIN="/usr/local/apache/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf"

• Is there really a need for encryption to have true wireless security? [closed]

  - by Cawas

  I welcome better key-wording here, both on tags and title. I'm trying to conceive a free, open and secure network environment that would work anywhere, from big enterprises to small home networks of just 1 machine. I think since wireless Access Points are the most, if not only, true weak point of a Local Area Network (let's not consider every other security aspect of having internet) there would be basically two points to consider here: Having an open AP for anyone to use the internet through Leaving the whole LAN also open for guests to be able to easily read (only) files on it, and even a place to drop files on Considering these two aspects, once everything is done properly... What's the most secure option between having that, or having just an encrypted password-protected wifi? Of course "both" would seem "more secure". But it shouldn't actually be anything substantial. That's the question, but I think it may need more elaborating on. If you don't think so, please feel free to skip the next (long) part. Elaborating more on the two aspects ... I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even consider hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what building walls is for the cables. And giving pass-phrases would be adding a door with a key. But the cabling without encryption is also insecure. If someone plugin all the data is right there. So, while I can see the use for encrypting data, I don't think it's a security measure in wireless networks. It's wasting resources for too little gain. I believe we should encrypt only sensitive data regardless of wires. That's already done with HTTPS, so I don't really need to encrypt my torrents, for instance. They're torrents, they are meant to be freely shared! As for using passwords, they should be added to the users, always. Not to wifi. For securing files, truly, best solution is backup. Sure all that doesn't happen that often, but I won't consider the most situations where people just don't care. I think there are enough situations where we actually use passwords on our OS users, so let's go with that in mind. I keep promoting the Fonera concept as an instance. It opens up a free wifi port, if you choose so, and anyone can connect to the internet through that, without having any access to your LAN. It also uses a QoS which will never let your bandwidth drop from that public usage. That's security, and it's open. But it's lacking the second aspect. I'll probably be bashed for promoting the non-usage of WPA 2 with AES or whatever, but I wanted to know from more experienced (super) users out there: what do you think?

• PPPTP VPN from Ubuntu cannot connect

  I'm trying to configure under Linux (Kubuntu 9.10) a VPN I already use from Windows. I installed the network-manager-pptp package and added the vpn under Network Manager.

• ubuntu wifi disconnection & frustratingly connects to unavailable wifi

  - by ashishsony

  Hi, i have already posted this here: here This has happened before with ubuntu 9.1 Beta2 build too that my wifi disconnects if im idle for 5 minutes... so i cant leave my lappy to download anything... i have to keep on continuously using it.. as soon i leave it idle for abt 5 minutes... wifi disconnects... and the pop up asking for password for wifi pops up...with the password already filled in... i just click on connect and it connects again... so whats the use of asking the password if the pre filled in pass works correctly... and this is happening on ubuntu 10.04 Beta2 too... and the workaround is that just open any menu like the applications menu in the taskbar and keep it open... under this state the ubuntu idleness never activates and so the wifi gets never disconnected... this has been confirmed by me many times.. this seems to be repeating again and again... i dont know why... and the second thing i want to report is that there is no way to report this bug from ubuntu... the launchpad.net talks of going through bug reporting process which is done against a definite package... now how does a user know which package would be causing this error?? there should be a more clear process of reporting such bugs to ubuntu team... thirdly the apport utility that reports crashing apps is totally uselss on 10.04 beta 2... as it collests information and reports that i cant submit the report because i dont have 100 other packages... without updating which i cant submit the report.... surely on a beta build there would be packages continuously being updated... so no system would be reported as fully updated... and so no practical apport reporting is possible?? please address these issues... really frustrating all this ... im a big fan of ubuntu but these things really bug me... and just to add fourthly... the suspend/hibernate feature has never ever worked on my toshiba m70-113 laptop... on any ubuntu version... always have to hard reboot after putting into suspend/hibernate mode.. on windows this has never been the case... why cant ubuntu beat windows in such cases too?? i would really like to see this soon... most importantly, when the router switches off... the wifi signals go off... then why the hell ubuntu keeps on connecting to that very wifi like hell and when doesnt connect shows the prompt to manually connect... with the wifi key already filled in... whats the use of saving the key when it has to ask the question from me either to connect or not?? and if its isnt available... just wait when its available.. i have only option to cancel and if i cancel it wont auto-connect!! what the heck?? one can see in the image that it says "authentication required by wireless network" when there isnt any.. as router has gone down!!

• Error installing pkgconfig via macports

  - by Greg K

  I installed Macports 1.8.2 from a DMG. That seemed to install fine. I ran sudo port selfupdate to make sure my ports tree was current. I then tried to install bindfs as I want to mount some directories in my OS X file system (like you can do with mount --bind in linux). pkgconfig and macfuse are two dependencies of bindfs.

• Cannot turn on "Network Discovery and File Sharing" when Windows Firewall is enabled

  - by Cheeso

  I have a problem similar to this one. Windows Firewall prevents File and Printer sharing from working and Why does File and Printer Sharing keep turning off in Windows 7? I cannot turn on Network Discovery. This is Windows 7 Home Premium, x64. It's a Dell XPS 1340 and Windows came installed from the OEM. This used to work. Now it doesn't. I don't know what has changed. In windows Explorer, the UI looks like this: When I click the yellow panel that says "Click to change...", the panel disappears, then immediately reappears, with exactly the same text. If I go through the control panel "Network and Sharing Center" thing, the UI looks like this: If I tick the box to "turn on network discovery", the "Save Changes" button becomes enabled. If I then click that button, the dialog box just closes, with no message or confirmation. Re-opening the same dialog box shows that Network Discovery has not been turned on. If I turn off Windows Firewall, I can then turn on Network Discovery via either method. The machine is connected to a wireless home network, via a router. The network is marked as "Home Network" in the Network and Sharing Center, which I think corresponds to the "Private" profile in Windows Firewall Advanced Settings app. (Confirm?) The PC is not part of a domain, and has never been part of a domain. The machine is not bridging any networks. There is a regular 100baseT connector but I have the network adapter for that disabled in Windows. Something else that seems odd. Within Windows Firewall Advanced Settings, there are no predefined rules available. If I click the "New Rule...." Action on the action pane, the "Predefined" option is greyed out. like this: In order to attempt to allow the network discovery protocols through on the private network, I hand-coded a bunch of rules, intending to allow the necessary UPnP and WDP protocols supporting network discovery. I copied them from a working Windows 7 Ultimate PC, running on the same network. This did not work. Even with the hand-coded rules, I still cannot turn on Network Discovery. I looked on the interwebs, and the only solution that appears to work is a re-install of Windows. Seriously? If I try netsh advfirewall firewall set rule group="Network Discovery" new enable=Yes ...it says "No rules match the specified criteria" EDIT: by the way, these services are running. DNS Client Function Discovery Resource Publication SSDP Discovery UPnP Device Host in any case, since it works with no firewall, I would assume all necessary services are present and running. The issue is a firewall thing, but I don't know how to diagnose further, or fix it. Q1: Is there a way to definitively insure the correct holes are punched through the Windows Firewall to allow Network Discovery to function? Q2: Should I expect the "predefined" firewall rules to be greyed out? Q3: Why did this change?

• Linux pptp client stops working after several hours

  - by Aron Rotteveel

  Here's the situation: Setup: 1 Windows Server 2008 machine acting as a Domain Controller and RRAS server 1 CentOS machine in a datacentre located elsewhere PPTP client running on CentOS machine, connected to the DC via When I connect to the DC, everything is working fine. I have set up a static IP for the dialup connection in my RRAS server so that the CentOS machine is automatically assigned the IP 192.168.1.240. Inside the VPN, it is not possible to access this machine on the local IP-address. Perfect. However, after several hours, it simply seems to stop working (IE: I cannot ping to or from this machine on the local network). The strange thing is, however: The DC shows the VPN client as still being connected The CentOS machine shows the network interface as being up There are no entries in my /var/log/messages that indicate a problem Output from ifconfig: ppp0 Link encap:Point-to-Point Protocol inet addr:192.168.1.240 P-t-P:192.168.1.160 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1396 Metric:1 RX packets:43 errors:0 dropped:0 overruns:0 frame:0 TX packets:58 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:4511 (4.4 KiB) TX bytes:15071 (14.7 KiB) Output from route -n: 192.168.1.160 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 ppp0 I have the following in my ip-up.local: route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0 The situation can be easily fixed by issueing a killall pppd and re-connecting. However, I obviously do not want to do this every X-hours or so. I have tried running pppd with both the debug as the kdebug flag but cannot find the cause of this problem.

• stunnel crashing

  - by Jay

  I'm trying to use stunnel to secure a legacy application's communications. I can't seem to get it setup and working. Can anyone provide any hints where I'm going wrong? Here's what I'm trying to accomplish: A windows service on a client machine connects to a server on port 7000 using TCP. I'd like to encrypt the communication between client and server. Here's what I've tried: Created a new server that accepts ssl connections on port 7443. Got a certificate for the server and installed it. That seems to work with my test setup. Installed stunnel on my windows machine (version 7.43 from the distribution archive file). Installed libssl32.dll and libeay32.dll in the same directory as stunnel.exe ( from the openssl-0.9.8h-1 binary distribution).

• CPU Temperature sensor wrong?

  - by Matias Nino

  Everest Ultimate is suddenly telling me that the CPU temperature (and core temps) for my E6850 Core 2 Duo is 72 degrees Celsius. When I stress-test the machine, the temp goes up to 91 degrees and the CPU actually throttles. System remains stable though. For over a year now, my CPU has run very cool (40's) with a large commercial copper heatsink/fan that I bought separately. To top it off, I removed the cover of the box and felt the cpu heatsink and it wasn't even warm. Is there such a thing as a CPU temp sensor showing the wrong readings? Any tips would help. UPDATE #1 Temp is also just as high in BIOS. So that leads me to believe it's a CPU seating issue (even though I used thermal paste to seat it two years ago when I built the machine) UPDATE #2 Well. I removed the heatsink and cleaned off the original thermal paste (which was somewhat crusty). I polished the surface, re-applied some new paste, and reseated the heat sink. After powering it up, there was no noticeable change in the temp - ideling at 74. Ran the stress test and it went up to 94 degrees before being 100% throttled. I let it sit at 94 degrees for 20 minutes straight and the computer didn't even flinch. I then immediately shut it off and opened the case and felt around. The heatsink was completely cold to the touch. Even the copper rods were cold. The area near contact with the CPU was slightly warm but not hot to touch. Then I ran REALTEMP, which is supposedly more accurate and it told me the CPU was at 104 degrees. (LOL) At this point, I'm thinking no doubt the cpu's sensor is wrong. Sidenote: the BIOS has the latest version so no option to flash there. Reverting hasn't been known to help from what I've read. What pisses me off is the false temps force the CPU to artificially throttle from 3GHz down to 2GHz and my CPU fan is cranking at full force all the time. Should I call intel and tell them to send me another E6850? SOLUTION UPDATE I switched the processor out with another one and got the same obscene temperatures with the new processor followed by a heatsink that was cool to touch. My suspicion in the heatsink was suddenly renewed. I swapped it out with the stock heatsink/fan and lo and behold the temperatures returned to the normal 35C-50C. Even though the thermal paste was visibly flattened out every time I removed it, it looks like the heatsink was still not pressing hard enough on the CPU to effectively conduct the heat. The heatsink is a Masscool 8Wa741, which screws into a standard position on a mount on the back of the MOBO. Only thing I can surmise after 2 years of use was that, over time, the heatsink pressure on the CPU gave way until the heat began to be ineffectively conducted. Lessons learned: Intel CPU's can run SUPER HOT (upwards of 95C) and still be stable. Heatsink's need to be VERY firmly pressed against the CPU to conduct heat.

• Can't launch glassfish on ec2 - can't open port

  - by orange80

  I'm trying to start glassfish on an EBS-based AMI of Ubuntu 10.04 64-bit. I have used glassfish on non-ec2 servers with no problems, but on ec2 I get this message: $ sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server. Command start-domain failed. I know that ec2 has requires that firewall rules be modified using ec2-authorize to let outside traffic thru the firewall, as I had to do to make ssh work. This still doesn't explain the port error when all I'm trying to do is start glassfish so I can try $ wget localhost:8080and make sure it's working. This is very frustrating and I'd really appreciate any help. Thanks. FINAL UPDATE: Sorry if you came here looking for answers. I never figured out what was causing the problem. I created another fresh instance, installed the same stuff, and Glassfish worked perfectly. Something obviously got boned during installation, but I have no idea what. I guess it will remain a mystery. UPDATE: Here's what I get from netstat: # netstat -nuptl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 462/sshd tcp6 0 0 :::22 :::* LISTEN 462/sshd udp 0 0 0.0.0.0:5353 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:1194 0.0.0.0:* 589/openvpn udp 0 0 0.0.0.0:37940 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:68 0.0.0.0:* 377/dhclient3 UPDATE: One more thing... I know that the "net.ipv6.bindv6only" kernel option can cause problems with java networking, so I did set this: # sysctl -w net.ipv6.bindv6only=0 UPDATE: I also verified that it has nothing at all to do with the port number (4848). As you can see here, when I changed the admin-listener port in domain.xml to 4949, I get a similar message: # sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4949 -- it probably is another instance of a GlassFish server. Command start-domain failed. UPDATE: Here are the contents of /etc/hosts: 127.0.0.1 localhost # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts I should mention that I have another Ubuntu Lucid 10.04 64-bit slice that is NOT hosted on ec2, and set it up the exact same way with no problems whatsoever. Also server.log doesn't offer much insight either: # cat ./server.log Nov 20, 2010 8:46:49 AM com.sun.enterprise.admin.launcher.GFLauncherLogger info INFO: JVM invocation command line: /usr/lib/jvm/java-6-sun-1.6.0.22/bin/java -cp /opt/glassfishv3/glassfish/modules/glassfish.jar -XX:+UnlockDiagnosticVMOptions -XX:MaxPermSize=192m -XX:NewRatio=2 -XX:+LogVMOutput -XX:LogFile=/opt/glassfishv3/glassfish/domains/domain1/logs/jvm.log -Xmx512m -client -javaagent:/opt/glassfishv3/glassfish/lib/monitor/btrace-agent.jar=unsafe=true,noServer=true -Dosgi.shell.telnet.maxconn=1 -Djdbc.drivers=org.apache.derby.jdbc.ClientDriver -Dfelix.fileinstall.dir=/opt/glassfishv3/glassfish/modules/autostart/ -Djavax.net.ssl.keyStore=/opt/glassfishv3/glassfish/domains/domain1/config/keystore.jks -Dosgi.shell.telnet.port=6666 -Djava.security.policy=/opt/glassfishv3/glassfish/domains/domain1/config/server.policy -Dfelix.fileinstall.poll=5000 -Dcom.sun.aas.instanceRoot=/opt/glassfishv3/glassfish/domains/domain1 -Dcom.sun.enterprise.config.config_environment_factory_class=com.sun.enterprise.config.serverbeans.AppserverConfigEnvironmentFactory -Dosgi.shell.telnet.ip=127.0.0.1 -Djava.endorsed.dirs=/opt/glassfishv3/glassfish/modules/endorsed:/opt/glassfishv3/glassfish/lib/endorsed -Dcom.sun.aas.installRoot=/opt/glassfishv3/glassfish -Djava.ext.dirs=/usr/lib/jvm/java-6-sun-1.6.0.22/lib/ext:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/ext:/opt/glassfishv3/glassfish/domains/domain1/lib/ext -Dfelix.fileinstall.bundles.new.start=true -Djavax.net.ssl.trustStore=/opt/glassfishv3/glassfish/domains/domain1/config/cacerts.jks -Dcom.sun.enterprise.security.httpsOutboundKeyAlias=s1as -Djava.security.auth.login.config=/opt/glassfishv3/glassfish/domains/domain1/config/login.conf -DANTLR_USE_DIRECT_CLASS_LOADING=true -Dfelix.fileinstall.debug=1 -Dorg.glassfish.web.rfc2109_cookie_names_enforced=false -Djava.library.path=/opt/glassfishv3/glassfish/lib:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64/server:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64:/usr/lib/jvm/java-6-sun-1.6.0.22/lib/amd64:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib com.sun.enterprise.glassfish.bootstrap.ASMain -domainname domain1 -asadmin-args start-domain,,,domain1 -instancename server -verbose false -debug false -asadmin-classpath /opt/glassfishv3/glassfish/modules/admin-cli.jar -asadmin-classname com.sun.enterprise.admin.cli.AsadminMain -upgrade false -domaindir /opt/glassfishv3/glassfish/domains/domain1 -read-stdin true

• What are the pitfalls of hardlinked files on my desktop PC?

  - by MountainX

  All the identical-content files on my PC are now hardlinked. (My data is completely de-duplicated. It is a consequence of the way I copied my data from my old computer.) What pitfalls do I need to be aware of now that certain actions on one file could silently affect a number of other files? I know that deleting the file I'm working on is not a problem (assuming I deleted it on purpose). It doesn't affect any of the other hardlinked files and I don't see that the delete action would lead to unexpected side effects. Moving or renaming the file is not a problem. I don't see any unexpected consequences. I don't think copying hardlinked files is a problem, but I'm not as confident about any unexpected consequences in this regard. What I have seen is that making a copy (to the same disk) of a hardlinked file with cp keeps the copy hardlinked (i.e., inode number doesn't change in the copy). Copying to another filesystem obviously breaks the hardlink. (I guess one pitfall is forgetting this fact, given that my PC has 3 hard disks.) Changing permissions does affect all linked files. So far this has proven handy. (I made a large number of the hardlinked files read-only.) None of the operations above seem to produce any major unexpected consequences. However, as was pointed out to me by Daniel Beck in a comment, editing or modifying a file can sometimes be a problem. It depends on the tool and maybe the type of edit. (For example, editing small text files using sed seems to always break the link while using nano doesn't.) This introduces the chance that editing one file could affect all the hardlinked files (i.e., alter the original inode). My proposed solution to this is to make all hardlinked files read-only (and that is already mostly the case). If I can't do that for some files, I will unlink those particular files. Is there any problem with this read-only approach? I'm assuming that if I go to edit a file and find it to be read-only, I'll remember to unlink that filename while making it writable. So one pitfall might be forgetting this rule. In that case, I'll have to rely on my backups. Am I correct in the above statements? And what else do I need to know? BTW, I'm running Kubuntu 12.04. I'm also using btrfs. (I have 2 SSD's and 1 HDD in the PC. I will also be adding an external USB HDD. I'm also connected to a network and I mount some NFS shares. I don't assume any of these last bits are relevant to the question, but I'm adding them just in case.) BTW, since I have more than one drive (with separate file systems), to unlink any file all I have to do is copy it to another drive, then move it back. However, using sed also works (in my testing). Here's my script: sed -i 's/\(.\)/\1/' file1 Surprisingly, this even unlinks zero byte files. In my testing it also appears to work on non-text files without any special options. (But I understand that the --binary option might be needed on Windows, MS-DOS and Cygwin.) However, copying to another disk and moving back may be the best way to unlink. For my use-case, unlink command doesn't really "unlink", rather it "removes".

• Huge performance difference between two web servers, odd behavior seen using process monitor

  - by Francis Gagnon

  We have two Coldfusion servers that have a huge performance difference running the exact same code on the exact same input data. The code in questions instantiates a large amount of CFCs (Coldfusion Components, which are similar to objects in OOP languages). I compared the two servers by running Process Monitor and then calling the problematic code on both machines. I learned two things. First, Coldfusion opens CFC files every time it instantiates an object. Both servers do this, so it cannot be the cause of the performance difference. Second, the fast server opens the CFC files directly while the server with the performance problem seems to navigate its way through the path until it reaches the desired CFC file. It does this for every file, even the ones it has previously loaded, and because the code instantiates so many CFCs it becomes very slow. See below the partial Promon traces that show this behavior. It can take over 60 seconds for the slow server to do what the fast one does in 2 seconds. Can anyone tell me what causes this behavior? Is it a Coldfusion setting? Since Coldfusion runs on top of Java, is it a Java setting? Is it an OS option? The fast server is running Windows XP and I think the slow server is a Windows Server 2003. Bonus question: Coldfusion doesn't seem to perform any READ FILE operations on any of the CFC or CFM files. How can this be?

• creating a heirarchy of terminals or workspaces

  - by intuited

  <rant This question occurred to me ('occurred' meaning 'whispered seductively in my ear for the 100th time') while using GNU-screen, so I'll make that my example. However this is a much more general question about user interfaces and what I perceive as a flawmissing feature in every implementation I've yet seen. I'm wondering if there is some way to create a heirarchy/tree of terminals in a screen session. EG I'd like to have something like 1 bash 1.1 bash 1.2 bash 2 bash 3 bash 3.1 bash 3.1.1 bash 3.1.2 bash It would be good if the terminals could be labelled instead of having to be navigated to via some arrangement that I suspect doesn't exist. So then you could jump to one using eg ^A:goto happydays or ^A:goto dykstra.angry. So to generalize that: Firefox, Chrome, Internet Explorer, gnome-terminal, roxterm, konsole, yakuake, OpenOffice, Microsoft Office, Mr. Snuffaluppagus's Funtime Carousel™, and Your Mom's Jam Browser™ all offer the ability to create a flat set of tabs containing documents of an identical nature: web pages, terminals, documents, fun rideable animals, and jams. GNU-screen implements the same functionality without using tabs. Linux and OS/X window managers provide the ability to organize windows into an array of workspaces, which amounts to again, the same deal. Over the past few years, this has become a more or less ubiquitous concept which has been righteously welcomed into the far reaches of the computer interface funfest. Heavy users of these systems quickly encounter a problem with it: the set of entities is flat. In the case of workspaces, an option may be available to create a 2d array. However none of these applications furnish their users with the ability to create heirarchies, similar to filesystem directory structures, containing instances of their particular contained type. I for one am consistently bothered by this, and am wondering if the community can offer some wisdom as to why this has not happened in any of the foremost collections of computational functionality our culture has yet produced. Or if perhaps it has and I'm just an ignorant savage. I'd like to be able to not only group things into a tree structure, but also to create references (aka symbolic links, aka pointers) from one part of the structure to another, as well as apply properties (eg default directory, colorscheme, ...) recursively downward from a given node. I see no reason why we shouldn't be able to save these structures as known sessions, and apply tags to particular instances. So then you can sort through them by tag, find them by name, or just use the arrow keys (with an appropriate modifier) to move left or right and in or out of a given level. Another key combo would serve to create a branch in the place of the current terminal/webpage/lifelike statue/spreadsheet/spreadsheet sheet/presentation/jam and move that entity into the new branch, then create a fresh one as a sibling to it: a second leaf node within the same branch node. They would get along well. I find it a bit astonishing that this hasn't happened yet, and the only reason I can venture as a guess is that the creators of these fine systems do not consider such functionality to be useful to a significant portion of their userbase. I posit that the probability that that such an assumption would be correct is pretty low. On the other hand, given the relative ease with which such structures can be implemented using modern libraries/languages, it doesn't seem likely that difficulty of implementation would be a major roadblock. If it could be done in 1972 or whenever within the constraints of a filesystem driver, it should be relatively painless to implement in 2010 in a fullblown application. Given that all of these systems are capable of maintaining a set of equivalent entities, it seems unlikely that a major infrastructure overhaul would be necessary in order to enable a navigable heirarchy of them. </rant Mostly I'm just looking to start up a discussion and/or brainstorming on this topic. Any ideas, examples, criticism, or analysis are quite welcome. * Mr. Snuffaluppagus's Funtime Carousel is a registered trademark of Children's Television Workshop Inc. * Your Mom's Jam Browser is a registered trademark of Your Mom Inc.
