xcin? I don't know. Check Chinese-Howto at LDP. I never bother to figure out how to input Chinese on Linux/Unix. I think windows has much better language support.
One other important thing is that you better patch it immediately. I've heard story saying that a stock installation of redhat got hacked in less than 2 weeks after putting it on the Internet.
请教：本人装了RedHat Linux 7.0, 请问阅读、输入中文的工具叫什么东东？
