Body
One option is to use VLC. You can specify a url on the command line. (see <a href="http://wiki.videolan.org/VLC_command-line_help" rel="nofollow noreferrer">here</a> for details). You could then write a brief shell script to open up all 5000 connections. eg. the following perl script (very quick hack - check before running, might cause explosions etc.) <pre class="lang-perl prettyprint-override"><code>$i = 0; $myurl = "udp://someurl"; @cmdline = ("/usr/bin/vlc", ""); for( $i = 1; $i <= 5000; $i++ ) { if( $pid = fork ) { # parent - ignore } elsif( defined $pid ) { $cmdline[1] = sprintf "%s:%d", $myurl, $i; exec(@cmdline); } # elseif - do more error checking here } </code></pre> If your video streaming server is doing multicast it should be sufficient to open sockets and make them members of your 5000 multicast groups (without necessarily doing anything with the stream. By not actually decoding the stream you will reduce performance issues on the client end). I'm not aware of any tools that will do this for you, but if you're up for writing your own utility you can start <a href="http://tldp.org/HOWTO/Multicast-HOWTO-6.html" rel="nofollow noreferrer">here</a> for details. edit: The second option assumes that the OS on your client machine has multicast capability. I mention that because (from memory) the linux kernel doesn't by default, and I'd like to save you that pain. :-) Easy way to tell (again on Linux) is to check for the presence of <code>/proc/net/igmp</code>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
