• How would I broadcast a subdomain/virtual name on a local server with people connected to the same network

  - by Sarmen B.

  I have a server connected to the router which has ubuntu 12.04. It is has apache/mysql/php all installed ready to go. the folder structure is like this: /var/www -- this isnt the root -/libs -/logs -/public - this is the root -/vhosts - all subdomains go here I have a folder in vhosts named mysite. I went into /etc/apache2/sites-available and created a file and here are the contents - (vhost file). and I also added an entry in /etc/hosts file containing: 127.0.1.1 mysite.dev and I also did sudo a2ensite mysite i tried accessing the site from a computer via mysite.dev and our public ip into the server but i was not able to view it. the public directory in the structure above does display on all computers when i try our public ip. but for anything added in vhosts the site wont show. there is no domain attached its just our ip. I tried changing the port from 80 to say 9999 in the mysite file in sites-available and tried myip:9999 but that didnt work either. what am I doing wrong? edit: i forgot to mention that the server is dmzed on the router.

• how to add a dynamic param

  - by user569846

  the jquery plugin that im using is this http://code.google.com/p/jquery-in-place-editor/ if i have a table like this <table> <thead> <tr> <th>id</th> <th>first name </th> <th>last name </th> </tr> </thead> <tbody> <tr> <td class="id">1</td> <td class="fname">sarmen</td> <td class="lname">mikey</td> </tr> <tr> <td class="id">2</td> <td class="fname">john</td> <td class="lname">angelo</td> </tr> <tr> <td class="id">3</td> <td class="fname">sarmen</td> <td class="lname">grande</td> </tr> </tbody> </table> and my js looked something like this $("td.fname").editInPlace({ url: 'ajax.php', params: '', show_buttons: true }); then lets say i click on the first record to edit it which is fname of sarmen. how can i pass a param that only accociates id 1 ? because if i do a query of lets say "update tbl_users set fname = '$_POST['update_value']' where fname = '$_POST['original_html']'" (note: im just showing an example so no need to clean posts if that was bothering you :) ) if i run this query the fname of sarmen will update in two records rather than one. How can i only update to id of 1 being to update only one record.

• How does a frame retrieve the recipient's MAC address?

  - by Sarmen B.

  I am studying a Network+ book named All-in-one CompTia Network+ by Mike Meyers. In chapter 2 he talks about frames and how he represents them as canisters and the data within the frame contains the recipients mac address, senders mac address, data, and sequence number. What I don't understand is if the sender is sending a file via the network to the recipient, and this frame contains this data, how does the frame know what the recipients MAC address is before sending it? In regards to TCP/IP when it contains the recipients IP address, that's understandable how it retrieves that value. But I don't understand how it can retrieve the MAC address, because if that frame comes from the senders computer, goes into the router and copies itself to each and every computer that exists on the network, how did it have the MAC address to know where to go? Let me know if I'm not making sense.
