this is your own machine right, not a vps?
then you should be able to connect to localhost no problem, if char_athena, and map_athena are default settings nothing changed then
here's my xml file, it may be no change but it should work
<?xml version="1.0" encoding="euc-kr" ?>
<clientinfo>
<servicetype>korea</servicetype>
<servertype>sakray</servertype>
<hideaccountlist /><extendedslot /><readfolder />
<connection>
<display>Sakray Client</display>
<desc>Sakray Client</desc>
<address>localhost</address>
<port>6900</port>
