• Unable to Turn On Media Streaming in Windows Media Player 12 on Windows 7

  - by Chau Chee Yang

  I have 2 PC installed with Windows 7 and Media Player 12. I would like to use Play To feature on both PC connected via LAN. Both PC (A and B) run media player in standard user account. I able to turn on media streaming option in PC A (with privilege access prompt) without any problem. However, PC B also prompt privilege access but no response after enter administrator password. Both PC follow same configuration steps. I may use "play to" PC A (in standard user account) from other PC without any problem. But I can't "play to" PC B in standard user account. I can only run media player in administrator account for "play to" to function. I have tried uninstall and reinstall media player via "Programs and Features" in control panel on PC B. However, it doesn't work too. Does anyone has similar experience as me failing to turn on media streaming that running Windows media player in standard user account?

• Kerberos & signle-sign-on for website

  - by Dylan Klomparens

  I have a website running on a Linux computer using Apache. I've employed mod_auth_kerb for single-sign-on Kerberos authentication against a Windows Active Directory server. In order for Kerberos to work correctly, I've created a service account in Active Directory called dummy. I've generated a keytab for the Linux web server using ktpass.exe on the Windows AD server using this command: ktpass /out C:\krb5.keytab /princ HTTP/[email protected] /mapuser [email protected] /crypto RC4-HMAC-NT /ptype KRB5_NT_PRINCIPAL /pass xxxxxxxxx I can successfully get a ticket from the Linux web server using this command: kinit -k -t /path/to/keytab HTTP/[email protected] ... and view the ticket with klist. I have also configured my web server with these Kerberos properties: <Directory /> AuthType Kerberos AuthName "Example.com Kerberos domain" KrbMethodK5Passwd Off KrbAuthRealms EXAMPLE.COM KrbServiceName HTTP/[email protected] Krb5KeyTab /path/to/keytab Require valid-user SSLRequireSSL <Files wsgi.py> Order deny,allow Allow from all </Files> </Directory> However, when I attempt to log in to the website (from another Desktop with username 'Jeff') my Kerberos credentials are not automatically accepted by the web server. It should grant me access immediately after that, but it does not. The only information I get from the mod_auth_kerb logs is: kerb_authenticate_user entered with user (NULL) and auth_type Kerberos However, more information is revealed when I change the mod_auth_kerb setting KrbMethodK5Passwd to On: [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(1939): [client xxx.xxx.xxx.xxx] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(1031): [client xxx.xxx.xxx.xxx] Using HTTP/[email protected] as server principal for password verification [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(735): [client xxx.xxx.xxx.xxx] Trying to get TGT for user [email protected] [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(645): [client xxx.xxx.xxx.xxx] Trying to verify authenticity of KDC using principal HTTP/[email protected] [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(1110): [client xxx.xxx.xxx.xxx] kerb_authenticate_user_krb5pwd ret=0 [email protected] authtype=Basic What am I missing? I've studied a lot of online tutorials and cannot find a reason why the Kerberos credentials are not allowing access.

• Hylafax: Encounter "No font metric information" when try to send a fax

  - by Chau Chee Yang

  I am using Hylafax 6.0.5 on Fedora 13 x86_64. As there are no rpm package available for Fedora 13, I use the source tar ball to install hylafax myself. Everything seems fine during compile and install. I try to send a fax with sendfax and encounter error: # sendfax -n -d <fax-number> /etc/passwd /usr/local/sbin/textfmt: No font metric information found for "Courier-Bold".

I have ghostscript-fonts installed too. I can't find hyla.conf in path /etc/hylafax. There is no /etc/hylafax path in my file system. All configuration files seems located in /var/spool/hylafax/etc. Please advice. Thank you.

• How to configure wpa_supplicant on RHEL6?

  - by Yang Jy

  I am running a version of RHCE6 on my laptop. I uninstalled the default NetworkManager in order that I could configure the network all in the command line. The Ethernet part is okay, but I have problem bringing up the wireless interface. What I got is: Bringing up interface wlan0: Determining IP information for wlan0... failed; no link present. Check cable? I did exactly what this article says. I am not sure if it is because the article is obsolete or something else. Please help.

• NFS automounts hang

  - by Yang

  Hi, I have been mounting NFS shares on my x86 Ubuntu with NIS/am-utils fine for a long time, but today my system got into a state where it could no longer access automounted directories and instead frequently got hung up trying to access them, returning either "Input/output error" or "Permission denied" (almost randomly), as well as "stale file handle." I can, however, manually mount that share fine. Restarting am-utils doesn't help get my system out of its funk; is there any other way of getting my system un-stuck?

• cron not even sending local mail to /var/mail/

  - by Yang

  I'm using a very plain Ubuntu Server 9.04, and cron isn't delivering any mail to my /var/mail/USER (the file hasn't even been created). Here's my full crontab: # m h dom mon dow command 15 * * * * $HOME/.cron/sync-bookmarks.bash If I add # m h dom mon dow command 15 * * * * $HOME/.cron/sync-bookmarks.bash >& /tmp/log then I see the stdout and stderr in /tmp/log. I'm not (yet) interested in actual remote email delivery, just local delivery to the mail spool file. Why isn't mail working? Thanks in advance for any tips.

• Is that possible to route all mails sent to a mailbox to another server's mailbox

  - by Chau Chee Yang

  I have a Linux server that has local mail service. There are few user accounts on this server. User may send the mail to each other but that only restrict to LAN environment only. For example, I may # mail user1 to send mail to user1. User are not able to send mail to public. Some service like hylafax using this local mail service to send notification of fax status. I don't want to manage and maintain local mail service anymore. I have subscribed a package from ISP to host a public domain of my own. I wish to have my hylafax service to able to send the notification mails to public mail server, is that possible to do it? It is great if all mails that send to local mail server may forward to public mail server. That makes the local mail service serve mail forward only.

• Nginx try_files or else continue matching against locations?

  - by Yang

  I'm wondering whether this is possible with Nginx: I just added a directory with a bunch of HTML files (foo.html, bar.html) that I'd like to serve with /foo, /bar, etc. If the URL doesn't match up with a file name I'd like to fall back to whatever the next best matching location would be. So I have: # This block is newly added. location ~ ^/([^/]+)$ { default_type text/html; alias /blah/$1.html; } # Our long list of existing subsystems below.... location /subscribe { proxy_pass http://127.0.0.1:5000; } location /upload { proxy_pass http://127.0.0.1:8090; proxy_read_timeout 99999; } location ~ /(data|garbage|blargh).* { proxy_pass http://127.0.0.1:8090; proxy_read_timeout 99999; auth_basic text; auth_basic_user_file /etc/nginx/htpasswd; } .... The problem is that the first regex now eats up the URLs that would've gone to other locations, as per the documented behavior of location. One approach is to maintain the full explicit list of files in the first location block, but this list is quite large and is always changing. Is there a way to check to see if the file exists first, and if not, then continue with what would've been the next-best location match? I took stabs using try_files (including using a @fallback and nesting locations in there) but I don't think it's capable of doing this. However I thought I'd ask here in case I'm missing something. (Or maybe there's another better approach altogether.)

• Is there any SMS/MMS server for LAN environment

  - by Chau Chee Yang

  I am looking for a solution to send SMS/MMS message to mobile device from desktop or browser in LAN environment. As such, it is most probably using TCP/IP protocol to transmit request/response. The server may attach to a GSM device with SIM card attached. An server application would then start accept the request from any LAN client and convey the SMS/MMS to one or more recipients. The server may log all requests for further traffic analysis in later stage. Is there any solution that able to perform what I describe here. Please advice.

• Google Reader offline sync (Gears) not syncing, stuck at 0%

  - by Yang

  I'm using Google Chrome, and for some reason starting over the weekend or Friday, I haven't been able to get Google Reader to sync for offline reading. When I hit the sync button, it just starts spinning and says: "Status: Downloading 2000 items...0% completed. Please wait..." There's no CPU, network, or disk activity on my machine, and it remains in this state indefinitely. I tried going to Chrome Settings, uninstalling Reader, navigating to Reader, and reinstalling Reader as a Gears app, to no avail. Any hints? Thanks in advance.

• How to prevent mod_proxy from rewriting redirects into absolute URLs?

  - by Yang

  I have: nginx (port 80) reverse-proxying to apache2 (port 88) reverse-proxying to a web app (port 5001). However, when the web app responds with a redirect like Location: /foo, apache2 rewrites this into Location: http://host.com:88/sub/foo, even though port 88 is publicly inaccessible. I'd like it to just redirect to the relative URL Location: /sub/foo. Any ideas? My apache config (using mod_proxy_http, mod_proxy_html, mod_substitute): <Location /notes/> Allow from all ProxyPass http://127.0.0.1:5001/ SetOutputFilter proxy-html ProxyPassReverse / ProxyHTMLURLMap / /notes/ RequestHeader unset Accept-Encoding AddOutputFilterByType SUBSTITUTE application/atom+xml Substitute "s|127.0.0.1:5001|host.com/notes|" </Location>

• How to configure sendmail to relay local user mail to public host?

  - by Chau Chee Yang

  I am using Linux/Fedora's sendmail as my mail server. The server do not has a public domain name. It connect to Internet via dial-up. There are few users in the server. I have successfully configure my sendmail to relay mail to public host (via smart_host): # mail <user>@gmail.com [email protected] receive mail from this private host. However, if I send a mail to local user (without domain name): # mail <user> All mails are deliver to my server's mail spooler (/var/spool/mail). I wish all mails send to local user may relay to a public domain that I have registered, is that possible to do so with sendmail? mail user1 will send mail to [email protected] mail user2 will send mail to [email protected]

• Recover open but deleted file on Linux using ln instead of cp

  - by Yang

  Say I have a file that's downloading (from a source that's hard to re-download from), but accidentally deleted from the filesystem namespace (/tmp/blah), and I'd like to recover this file. Normally I could just cp /proc/$PID/fd/$FD /tmp/blah, but in this case that would only get me a partial snapshot, since the file is still downloading. Furthermore, once the download completes, the downloading process (e.g. Chrome) will close the FD. Any way to recover by inode/create a hard link? Any other solutions? If it makes any difference, I'm mainly concerned with ext4. Thanks in advance.

• How to set up a PRIVATE vimwiki on Dropbox.com

  - by Zongheng Yang

  Hi everyone, I assume those who are reading this page know what vimwiki and dropbox.com are and what they are for, so I might directly go into my confusion. The common way of setting a PRIVATE vimwiki on dropbox is simply let your vimwiki directories be under Dropbox folder (but not Dropbox/Public/ because it would be PUBLIC). Dropbox allows directly viewing html with dropbox.com/* url: for example a index.html can be accessed by url https://dl-web.dropbox.com/get/Wiki/html/index.html?w=bfead71a, being added after the file name a specified string, ?w=bfead71a. Hence, if inside index.html there is reference to A.html, which is located in the same folder index.html is in, it has to be accessed using some url like https://dl-web.dropbox.com/get/Wiki/html/index.html?w=SPECIFIED_STRING. But it is seemingly impossible to hack vimwiki in order to make the hrefs in converted htmls corrected in this way. Is there some approach that can resolve this problem? I hope I make myself clear. Had you any questions, please ask me for further explanations. Thank you!

• How can I make the NetworkManager work?

  - by Yang Jy

  I am running a version of RHCE6 on my laptop, and lately I've been trying various stuff about network configuration through command line. Last night, I tried removing the NetworkManager using "yum remove NetworkManager" from the system, so that I could have more control of the network through the command line. But the result is, I didn't manage to configure the wireless connection through wpa_supplicant, and I need wireless connection during my travel to another place. So I need the wireless function back as soon as possible. I typed " yum install NetworkManager", some version installed, but I don't get to have an icon on the taskbar, and of course, the network doesn't work. The package I previously removed(about 24MB) was much larger that the one I just installed(about 2MB), so I think some dependencies must be missing. How could I install all these dependencies? Please help!

• Tuning SQL Server 2008 for web applications

  - by Kibbee

  In one of the Stackoverflow podcasts, I remember Jeff Atwood saying that there was a configuration option in SQL Server 2008 which cuts down on locking, and was kind of an alternative to using "with (nolock)" in all your queries. Does anybody know how to enable the feature he was talking about, possibly even Jeff himself. I'm looking at deploying SQL Server 2008, and want to see if using a feature like this would help out my web application.

• A couple PHP/MySQL questions...

  - by Jeff

  I am a college student taking a course in php and mysql progamming and my first question is about the "$variable" variables in the following code: <?php ob_start(); ?> <?php session_start(); if ($_SESSION['auth'] != "true") { header("Location: login.php"); exit; } $uid = $_SESSION['user']; $connection = mysql_connect("localhost", "username", "password"); mysql_select_db("username", $connection); $result = mysql_query ( "SELECT * FROM users where user_id = '$uid'", $connection); $num = mysql_numrows($result); $i=0; while ($i < $num) { $f1=mysql_result($result,$i,"firstname"); $f2=mysql_result($result,$i,"lastname"); ?> <html><body> <p> <td><center><font size = "18" face="Arial"><?php echo "Name: $f1 "; echo $f2; ?> </font></center></td> </p> </body></html> <?php $i++; } ?> <?php $result1 = mysql_query ( "SELECT * FROM phone where user_id = '$uid'", $connection); $num1 = mysql_numrows($result1); $j=0; while ($j < $num1) { $f3=mysql_result($result1,$j,"type"); $f4=mysql_result($result1,$j,"number"); ?> <html><body> <p> <br> <td><center><font size = "12" face="Arial"><?php echo "$f5: "; echo "($f3) "; echo "$f4 <br />"; ?> </font></center></td> </p> </body></html> <?php $j++; } ?> <?php $result2 = mysql_query ( "SELECT * FROM address where user_id = '$uid'", $connection); $num2 = mysql_numrows($result2); $h=0; while ($h < $num2) { $f6=mysql_result($result2,$h,"type"); $f7=mysql_result($result2,$h,"address"); $f8=mysql_result($result2,$h,"city"); $f9=mysql_result($result2,$h,"state"); $f10=mysql_result($result2,$h,"zip"); ?> <html><body> <p> <br> <td><center><font size = "12" face="Arial"><?php echo "$f10 Address: $f6, $f7, $f8 $f9"; ?></font></center></td> </p> </body></html> <?php $h++; } ?> <?php include 'navbar.php'; ob_end_flush(); ?> I just don't really understand the $variables at all. Are they user-generated or are they entities in the database? And how does the code know which $result is which? My second question is that, if this was someone else in my class's code and I wanted to modify it to make it my own and substitute my own variables, how would I go about doing that? Do the $variables need to be changed if they are not user-defined and if so, how? I apologize if these are dumb questions, but I am a beginner at this programming language. Thanks in advance for your help. -Jeff

Shoutouts: In with the links I've listed below, Sigurd Snørteland also sent a link to this app he's working on which is actually pretty cool to see: ZuneLight. The code is not yet available. He also has a no-code demo of a Silverlight Media Center Pieter Voloshyn, Luiz Thadeu, and Jhun Iti have a very nice Silverlight image editor up: Thumba From SilverlightCream.com: WP7 - Silverlight on mobile Sigurd Snørteland submitted some links for me that have been translated to English from his blog. I hope the pages come out good because he's got a lot of good stuff on there. This one has a link to a presentation he did, and 4 projects you can load up in the emulator that he's converted to the phone: weather, worldclock, coverflow, and solitaire ... pretty cool... thanks for the links Sigurd!
