求教高手，关于安装sybase的问题？？急！！！

Question

我在安装sybase时，sybase版本是11。9。2，用的是./srvbuildres -r ./sql.rs建立ASE；用./srvbuildres -f ./sqlbak.rs建立back,
启动是正常，但是不能进行dump 和load
interfaces 文件如下
CHINA
        master tcp ether 192.168.100.224 5000
        query tcp ether 192.168.100.224 5000

CHINA_back
        master tcp ether 192.168.100.224 6000
        query tcp ether 192.168.100.224 6000

sql.rs如下：
sybinit.release_directory: /opt/sybase-11.9.2
