even I do not know Ignite-UX, it should be simple to change:<br />
first locate all files containing your hostname and/or IP:<br />
&nbsp; find / -type f -exec egrep 'yourhostname|yourIP' {} \;<br />
<br />
(replace yourhostname and yourIP appropriate)<br />
<br />
Then edit these files, changing to new values.<br />
Then reboot.

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.
