说明网络不是问题

server:(通过 ssh 进来)
root@loongson:~# /etc/init.d/xrdp restart   //启动 xrdp 服务，结果出错
Stopping xrdp: sesman xrdp.
Starting xrdp: It looks like xrdp is allready running,
if not delete the xrdp.pid file and try again
xrdp sesman.

解决方法：

查看是否还有xrdp 进程在运行
root@loongson:~# ps -A | grep sesman
13644 pts/3    00:00:00 sesman
root@loongson:~# ps -A | grep xrdp     

显示没有xrdp 进程在运行，启动 xrdp  进程
root@loongson:~# /etc/init.d/xrdp start    //依然出错
Starting xrdp: It looks like xrdp is allready running,
if not delete the xrdp.pid file and try again

删除 xrdp.pid 文件再启动
root@loongson:~# rm /var/run/xrdp/xrdp.pid
root@loongson:~# # /etc/init.d/xrdp start
Starting xrdp: xrdp sesman.

root@loongson:/var/run/xrdp# netstat -tnl

出现有上面的 3389 端口监听，则说明 xrdp 启动起来了
