• Playing an Online mp3

  - by Mohsen

  I have a problem with playing online mp3s. I'm using latest version of javazoom's jlayer and basicplayer. Here is the exception: Caused by: javazoom.jlgui.basicplayer.BasicPlayerException: java.io.EOFException at javazoom.jlgui.basicplayer.BasicPlayer.initAudioInputStream(Unknown Source) at javazoom.jlgui.basicplayer.BasicPlayer.open(Unknown Source) ... 12 more Caused by: java.io.EOFException at java.io.DataInputStream.readInt(DataInputStream.java:375) at com.sun.media.sound.WaveFileReader.getFMT(WaveFileReader.java:244) at com.sun.media.sound.WaveFileReader.getAudioFileFormat(WaveFileReader.java:85) at javax.sound.sampled.AudioSystem.getAudioFileFormat(AudioSystem.java:985) at javazoom.jlgui.basicplayer.BasicPlayer.initAudioInputStream(Unknown Source) ... 15 more My java is 1.6.0_16. Certain files cannot be player through the Internet. I have a set of mp3s, playing one after the other. Randomly one mp3 doesn't work throwing above exception. Some mp3s can be played by calling again play() method if javazoom's basicplayer, but others can never be played online. I was able to find this post but I doubt if this really relates to my directx version or something. Mohsen

• Eclipse on mac: how comes that everytime I install an Eclipse plug-in on my mac I always get this er

  - by Patrick

  I'm using Eclipse for several projects on Leopard OSX. I've installed several versions (Classic, PDT, etc). When I install a new plug-in using the Help Install New Software functionality and I restart it, I always get the same error and I cannot anymore use it: !ENTRY org.eclipse.equinox.launcher 4 0 2010-04-20 17:32:42.540 !MESSAGE Exception launching the Eclipse Platform: !STACK java.lang.ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:317) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:556) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:514) at org.eclipse.equinox.launcher.Main.run(Main.java:1311) What is causing the error?

• deploying a Python application from a PHP developer

  - by user1218776

  I'm a little confused on the deployment process for Python. Let's say you create a brand new project with virtualenv source bin/activate pip install a few libraries write a simple hello world app pip freeze the dependencies When I deploy this code into a machine, do I need first make sure the machine is sourced before installing dependencies? I don't mean to sound like a total noob but in the PHP world, I don't have to worry about this because it's already part of the project. All the dependencies are registered with the autoloader in place. The steps would be: rsync the files (or any other method) source bin/activate pip install the dependencies from the pip freeze output file It feels awkward, or just wrong and very error prone. What are the correct steps to make? I've searched around but it seems many tutorials/articles make an assumption that anyone reading the article has past python experience (imo).

• How to browse Windows XP from Mac Finder when name disappears from finder

  - by Chris

  Occasionally, like right at this moment, I cannot access my windows share from my mac. Normally, it works, but every now and then, the computer name won't be displayed under SHARED in Finder. Rebooting the windows computer usually fixes this, but it's inconvenient. The Windows computer can see the Mac on the network. Is there a method of asking finder to poll for windows shares again, or "forcing" finder to look for "desktop"? I'm looking for the equivalent of \desktop in the address bar of a Windows computer. Thanks for the help.

• Printing perforated business cards

  - by Gio Borje

  I have a Brother MFC 440CN printer with the paper loaded underneath it. The problem with my stack of perforated business cards is that I can't print double-sided. The printer pulls the paper out from under its paper tray below and rolls it through the top for printing. With perforated business cards, they paper breaks at the perforations. Is there a method to preventing the slicing? Also, my printer also has some trouble pulling up the paper in general but I don't seem to understand why other than that the perforations break before the paper is grabbed for printing.

• Strange requests coming from Korean Site

  - by Jim Jeffers

  Lately I've been finding a lot of strange requests like this coming to my rails app: Processing ApplicationController#index (for 189.30.242.61 at 2009-12-14 07:38:24) [GET] Parameters: {"_SERVER"=>{"DOCUMENT_ROOT"=>"http://www.usher.co.kr/bbs/id1.txt???"}} ActionController::RoutingError (No route matches "/browse/brand/nike ///" with {:method=>:get}): It looks like it's automated as I get a lot of them and notice the strange parameters they're trying to send: _SERVER"=>{"DOCUMENT_ROOT"=>"http://www.usher.co.kr/bbs/id1.txt??? Is this something malicious and if so what should I do about it?

• Using Apache / Kerberos / Keytab to Authenticate Redmine Users Against Active Directory

  - by David Kaczynski

  Please bare with me, as I am still fresh to these technologies. We have a Debian (squeeze) server to which I have root access. It is running Apache, and Redmine is deployed to the server (currently using a local MySQL database for authentication). Apache is configured to use Kerberos and a keytab file to authenticate users against Active Directory. With the current configuration, as soon as a user attempts to access anything over https, the user is prompted for a username / password, which is successfully authenticated against Active Directory. I understand (somewhat) that Redmine has its own LDAP configuration that can be used to authenticate users against an existing Active Directory, but this would require the user to enter their credentials one time for Apache and then a second time for Redmine. I am wondering, Can I somehow configure Redmine to share the Apache authentication method as opposed to requiring the user to enter their credentials a second time? (Using Apache to authenticate against Active Directory is a requirement for a separate application on the server)

• Network / Internet diagnostic tool to locate an error?

  - by Jesper

  Hi, I’m facing some difficulties with the Internet / network at my work and I have trouble locating the precise error and when and how it occurs. The problem is that the client machines in the house sporadic is disconnected to the Internet. I’m some what new so I haven’t that much inside in the network and apparently neither has my predecessor. What I am requesting and hoping you guys knows about is, if there exist some kind of network monitor tool I can install and run and it will periodically check the network, the Internet connection etc. and record to logs. Then, if there suddenly arises a problem some time of the day in some part of the network or the Internet connection, I can check it perhaps the next day. I’ve just downloaded and installed Microsoft Network Monitor 3.3 application and hopeful it can give me some answers on where the instability is located but I still would like a tool to make different checks and test in some time interval. Do anyone know about such a program or another kind of performance / diagnostic tool / method I can use? Sincere Jesper

• Can I easily use a VPN to duplicate SSH Tunneling functionality?

  - by Steve V.

  Right now, when I want to use an unsecured wireless connection with my (Linux) laptop, I secure my connection using a variation of the method provided here. However, to the best of my knowledge, the (non-jailbroken) iPad does not allow applications to tunnel traffic through local ports. However, it does seem to allow certain VPN traffic. I have never set up, or even used, a VPN before. I'm looking for confirmation that I'm not barking up the wrong tree before I invest significant effort into setting up my own VPN server. If I want to secure my wireless iPad traffic over an unsecure wireless connection, would I be on the right track by looking at a VPN?

• Filezilla FTP Server - Security Implications of its usage on Windos Server 2003

  - by Brian Webster

  I'm running Filezilla server on my dedicated windows 2003 server. It uses its own user-access control system. The Filezilla server service itself is running under the System user. When I setup users within the FTP Server Administrator Interface, I do not need to setup equivalent users, or adjust permissions on folders to allow users to login. Example: I setup TestFTP user with password 'p' I set the home directoy of TestFTP user to be e:/website I verify that e:/website only has permission for the System and Admin accounts (right click - security in windows explorer) TestFTP is able to login to the server just fine. I'm OK with this (perhaps due to ignorance?). Is it generally frounded upon to utilize a FTP Server such as FileZilla Server that bypasses the built-in UAC in this method? If I wasn't clear enough, please let me know.

• ReadyNAS issue with Google Apps?

  - by Jauder Ho

  The power went out (again) in my house today so I decided to set up some alerting. Since I have a ReadyNAS and the latest version of Raidinator seems to have SMTP TLS support, I figured I would try setting things up to email to a domain I have hosted on Google Apps. At this point, I have everything working IF I use a Gmail account but as soon as I switch to a Google Apps email address, it stops working and complains with smtpstatus=535 smtpmsg='535-5.7.1 Username and Password not accepted. Learn more at \n535 5.7.1 http://mail.google.com/support/bin/answer.py?answer=14257 30sm16076226wfd.23' errormsg='authentication failed (GNU SASL, method PLAIN)' exitcode=EX_NOPERM I'm wondering if anyone else has encountered this. Google's extremely aggressive captcha does not help but I am able to log in now without a captcha from a browser so I'm open to any ideas why the simple switch of a user/password combo that is supposed to work does not. I'm also attaching my config so that others can see how to set things up.

• awstats parse of postfix mail log drops all records

  - by accidental admin

  I'm trying to get awstats to parse the postfix mail log, but it drops allmost all entries with messages like: Corrupted record (date 20091204042837 lower than 20091211065829-20000): 2009-12-04 04:28:37 root root localhost 127.0.0.1 SMTP - 1 17480 Few more are dropped with an invalid LogFormat: Corrupted record line 24 (record format does not match LogFormat parameter): 2009-11-16 04: 28:22 root root localhost 127.0.0.1 SMTP - 14755 My conf LogFormat="%time2 %email %email_r %host %host_r %method %url %code %bytesd" I believe matches the log format (and besides is the log format I've seen everywhere for awstats mail parsing). Besides, is the same entry format as all the other entries in the mail log. Whatever is left is dropped too: Dropped record (host localhost and 127.0.0.1 not qualified by SkipHosts): 2009-12-07 04:28:36 root root localhost 127.0.0.1 SMTP - 1 17152 I added SkipHosts="" to the .conf file but to no avail. I feel like awstats really has some personal quarrel with me today.

• http://localhost:8080 is not working on running apacher Server through XAMPP

  - by Dinesh Kumar

  I am unable to configure a PHP/MySQL/Apache environment on my local machine using XAMPP. In my xampp control panel the Apache and MySQL status is as started, but localhost is not working. I have tried the following method but still i am unable to execute: I tried to reinstall after uninstalling several time. I changed the "Listen 80" to Listen localhost:80, localhost:8080, 127.0.0.1:80,127.0.0.1:8080, MySystemIP:80/8080 and tried to execute the relevant url in my browser. I executed the netstat -noa and tasklist and found Apache is is using Port80. Skype is also not using the port80. I edited the firewall to allow port80. Also disabled the firewall. Is there any other solution to fix my problem. I remember 8 months back everything worked properly. Now when i try to reinstall xampp the issue raised it. I am Using Win-xp os. Thanks in advance

• IIS is overriding my response content, if i manually set the Response.StatusCode

  - by Pure.Krome

  Hi Folks, Problem when i manually set the HTTP Status of my Response stream to .. say 404 or 503, IIS renders up the stock IIS content/view, instead of my custom view. When I do this with the Web Development Server (aka. Casinni), it works correctly (ie. my content is displayed and the response.statuscode == my entered data. Is there anyway I can override this behaviour? How To Replicate Make a default ASP.NET MVC1 web app. Add the following route public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{*catchall}", new { controller = "Home", action = "Index" } ); } Now replace the the HomeController's Index method with...

• Can't log in via SSH to any accounts set to use /bin/bash as a default shell

  - by Gui Ambros

  I'm trying to install bash as the default shell on a ARM Linux running on an embedded device (Synology DS212+ NAS). But there's something really wrong, and I can't figure out what it is. Symptoms: 1) Root has /bin/bash as default shell, and can log in normally via SSH: $ grep root /etc/passwd root:x:0:0:root:/root:/bin/bash $ ssh root@NAS root@NAS's password: Last login: Sun Dec 16 14:06:56 2012 from desktop # 2) joeuser has /bin/bash as default shell, and receives "Permission denied" when trying to log in via SSH: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/bash $ ssh joeuser@localhost joeuser@NAS's password: Last login: Sun Dec 16 14:07:22 2012 from desktop Permission denied, please try again. Connection to localhost closed. 3) changing joeuser's shell back to /bin/sh: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/sh $ ssh joeuser@localhost Last login: Sun Dec 16 15:50:52 2012 from localhost $ To make things even more strange, I can log in as joeuser using /bin/bash using the serial console (!). Also a su - joeuser as root works fine, so the bash binary itself is working fine. In an act of despair, I changed joeuser's uid to 0 on /etc/passwd, but also didn't work, so it doesn't seem to be anything permission related. Seems that bash is doing some extra checking that sshd didn't like, and blocking the connections for non-root users. Maybe some sort of sanity checking - or terminal emulation - that is triggering the SIGCHLD, but only when called via ssh. I already went through every single item on sshd_config, and also put SSHD in debug mode, but didn't find anything strange. Here's my /etc/ssh/sshd_config: LogLevel DEBUG LoginGraceTime 2m PermitRootLogin yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys ChallengeResponseAuthentication no UsePAM yes AllowTcpForwarding no ChrootDirectory none Subsystem sftp internal-sftp -f DAEMON -u 000 And here's the output from /usr/syno/sbin/sshd -d, showing the failed attempt of joeuser trying to log in, with /bin/bash as the shell: debug1: Config token is loglevel debug1: Config token is logingracetime debug1: Config token is permitrootlogin debug1: Config token is rsaauthentication debug1: Config token is pubkeyauthentication debug1: Config token is authorizedkeysfile debug1: Config token is challengeresponseauthentication debug1: Config token is usepam debug1: Config token is allowtcpforwarding debug1: Config token is chrootdirectory debug1: Config token is subsystem debug1: HPN Buffer Size: 87380 debug1: sshd version OpenSSH_5.8p1-hpn13v11 debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: read PEM private key done: type ECDSA debug1: private host key: #2 type 3 ECDSA debug1: rexec_argv[0]='/usr/syno/sbin/sshd' debug1: rexec_argv[1]='-d' Set /proc/self/oom_adj from 0 to -17 debug1: Bind to port 22 on ::. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on :: port 22. debug1: Bind to port 22 on 0.0.0.0. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on 0.0.0.0 port 22. debug1: Server will not fork when running in debugging mode. debug1: rexec start in 6 out 6 newsock 6 pipe -1 sock 9 debug1: inetd sockets after dupping: 4, 4 Connection from 127.0.0.1 port 52212 debug1: HPN Disabled: 0, HPN Buffer Size: 87380 debug1: Client protocol version 2.0;

• What's the simplest configuration of SVN on a Windows Server to avoid plain text password storage?

  - by detly

  I have an SVN 1.6 server running on a Windows Server 2003 machine, served via CollabNet's svnserve running as a service (using the svn protocol). I would like to avoid storing passwords in plain text on the server. Unfortunately, the default configuration and SASL with DIGEST-MD5 both require plain text password storage. What is the simplest possible way to avoid storing passwords in plain text? My constraints are: Path-based access control to the SVN repository needs to be possible (currently I can use an authz file). As far as I know, this is more-or-less independent of the authentication method. Active directory is available, but it's not just domain-connected windows machines that need to authenticate: workgroup PCs, Linux PCs and software that uses PySVN to perform SVN operations all need to be able to access the repositories. Upgrading the SVN server is feasible, as is installing additional software.

• Changing The Text Selection Shortcuts on a Mac

  - by Berk U.

  I've recently switched over from a PC to a Mac and I'm wondering if there is any way to edit the text selection/deletion shortcuts on a Mac. I write a lot of code and I've found these shortcuts to be very helpful. Here is a quick overview of the deletion shortcuts (http://lifehacker.com/5803041/the-mac-os-x-delete-key-it-goes-both-ways); the selection shortcuts on the mac are similar, except that you can use arrow keys instead of delete. I'd be happy to learn of any method, though I would much prefer it if someone can come up with a way to do it using KeyRemap4MacBook.

• VMware networking - PortChannel or not?

  - by dunxd

  My ESX hosts each have 8 NICS. I have set up 2 NICs for our iSCSI SAN - each is connected to a different SAN switch. 2 NICs are set up for vMotion and Service Console - these are each connected to a different core switch (ports are trunked with VLANs dedicated to vMotion and Management) I now have four ports left over. Currently we have these set up each going into our default VLAN. Two NICs are connected to one core-switch and two are connected to the other. We decided to aggregate the connections to each switch - so they are teamed at the vswitch end, and port channelled at the physical switch end. I am now reading that port channelling these connections is not particularly useful, perhaps even over complicating things. Is there a particular problem with using port channels for VMware? What method provides the best balance between redundancy and performance?

• Pause/play AJAX on particular tabs in firefox

  - by bguiz

  Hi, I want to know if there is some method to disable AJAX on particular tabs within Firefox and re-enable them later. My concern is that I have metered bandwidth, and I need to conserve my usage. But I also like to leave several Gmail tabs open in the background. It would be great if I could just hit a "Pause AJAX" button, to stop the contents of that tab from sending or receiving anything, and then later on hit a "Play" button when I want it to start doing its thing again. Any suggestions?

• Trackpad and battery on stop working at same time

  - by Alex Krycek

  Gateway E-475M G Windows 7 Professional SP1 Synaptics TouchPad 15.2.20.0 Microsoft ACPI-Compliant Control Method Battery 6.1.7600.16385 It seems that when my battery stops working correctly, my touchpad will also act erratically. Specifically, the computer will charge for a few seconds, then stop charging for another few seconds. This will continue for some time. But if I close the lid, the charging LED will stay lit. As for the touchpad, it'll click or highlight things at random when I can get it to move. As a test, I stopped charging my computer. Now it seems my touchpad is working fine. I've tried to reinstall both the battery and touchpad drivers. I've also started the computer in safe mode, but that didn't help either. Edit: I've now tried booting my computer with an Ubuntu live cd, and the charging problem persists. So, it now seems my computer can only charge continuously as long as it's turned off or sleeping.

• Reinstall after a Root Compromise?

  - by Zoredache

  After reading this question on a server compromise, I started to wonder why people continue to seem to believe that they can recover a compromised system using detection/cleanup tools, or by just fixing the hole that was used to compromise the system. Given all the various root kit technologies and other things a hacker can do most experts suggest you should reinstall the operating system. I am hoping to get a better idea why more people don't just take off and nuke the system from orbit. Here are a couple points, that I would like to see addressed. Are there conditions where a format/reinstall would not clean the system? Under what types conditions do you think a system can be cleaned, and when must you do a full reinstall? What reasoning do you have against doing a full reinstall? If you choose not to reinstall, then what method do you use to be reasonably confident you have cleaned and prevented any further damage from happening again.

• Getting rid of site-specific hotkeys

  - by ZyX

  How do I disable site-specific hotkeys if (and only if) they are already mapped in Opera? For example, I use <C-b> instead of <Right> and <C-h> instead of <BS>. On Stack Overflow/Super User they produce **strong text** and ## Heading ## respectively. I do not want this happen. I can examine Super User/Stack Overflow/some_other_site's javascript and write a userjs to do the job, but this method is not universal. I'm using Opera-10.51_pre6252 in Gentoo Linux.

• securing server to server http post

  - by ad-inf

  Website is developed on JSF, Servlet, using apache web server. In my website, I accept data submission from few restricted websites using HTTP POST method. We exchange some secure key to ensure that correct source is sending data. But is there any way to ensure that the data is submitted from specific domain / IP address only? In application level I can check request.header('Referer') , but some proxy or firewall might hide the referer. Can this configuration done on firewall or webserver level to authenticate server to server communication? Eg. Say my website is a payment gateway website, integrated with www.abc.com. I want only abc.com to submit data. So a user using abc.com should be able to submit data to my website only through abc.com, and not any other website.

• SSH login to Cisco switch using Rancid times out

  - by Lars

  I have a 3560 switch that I have configured to accept SSH logins, and this works fine. However I cannot get Rancid to complete the login process to any of my switches using SSH. I get a timeout error after a minute or so. Telnet logins work fine with the same username and password. Here is my rancid setup in .cloginrc: add user * {myuser} add password * {strongAccessPassword} {strongEnablePassword} add method * ssh telnet Then, when I run bin/clogin 10.10.1.10 I get: # bin/clogin 10.10.1.10 10.10.1.10 spawn ssh -c 3des -x -l myuser 10.10.1.10 ############################################### Please authenticate. ############################################### Password: Error: TIMEOUT reached Again, when I do this using telnet as my preferred mothod in .cloginrc, it works without issue.
