Check your Internal text in client. Make sure you have your correct I.P there. Ping your centos machine make sure your connection is bridged to your sql. Make sure your firewall is not blocking your connection on your windows side. Make sure your connections are correct on centos and a network connection has been made. Log into centos and type "setup" with out quotes, put your centos i.p there and just hit enter than exit out of setup. restart centos by typing "service cabal restart" Than try to relog. Hope this helps sounds like you need to just double check your connections...
