looks like there may be a column missing from the output, I would have thought you should see the port numbers udp is listening on and they are probably related to services.<br />
<br />
If it's linux try running netstat -taupen which will give a full list and the daemon associated with the port.

<div class="content wysiwyg-content">
When running the netstat command with the 'a' and 'n' options, the output includes numerous lines resembling the following:<br />
<br />
udp &nbsp; &nbsp; &nbsp; &nbsp;0 &nbsp; &nbsp; &nbsp;0 &nbsp;*.* &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;*.*<br />
<br />
What does this mean. I'm concerned about the sheer number of them (there are 945 such records). Is this a problem?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
