最近在博创的开发板上挂载nfs系统时,老是挂不上:请大家帮帮忙。查了资料,可是仍然没有解决。弄了很长时间了,请大家帮帮忙。
开发板: 博创s3c2410-s arm9
电脑系统: fedora
设置了电脑上的ip: 192.168.0.121 ,关闭了防火墙!开启了nfs服务,共享目录为:/ykenfs
开发板上的ip: 192.168.0.115,
用ping命令能互相ping开发板和pc机。但是就是挂载不上,
当在未连接开发板时,系统也mount不上自己:
用了:mount 192.168.0.121:/ykenfs /mnt
昨天能够在pc上自己mount上自己,可是在连接上开发板之后,pc也不能mount上自己了,从开发板里边的linux系统也不能挂载上这个nfs,下面是从开发板上出的错误信息,请大家帮帮忙!呵呵,非常感谢!

开发板上的系统运行:ifconfig后的显示结果为:
