2、wireshark抓包信息




3、客户端设置：
ipaddr=192.168.0.104
bootcmd=tftp 72000000 uImage ;bootm 0x72000000
serverip=192.168.0.107
bootargs=mem=64M console=ttyS0 115200 root=/dev/nfs rw nfsroot=192.168.0.107:/home/radionfs,rsize=1024,wsize=1024,nfsvers=3,proto=tcp
ip=192.168.0.104:192.168.0.107:192.168.0.1:255.255.255.0::eth0:0ff


请教：  NFS挂载失败的原因？我使用的fedora10,   内核文件使用为：linux-2.6.30
是否是因为NFS服务器发送的数据包大小过大，导致客户端无法接收？
那么怎样将NFS服务器设置为客户端需要的数据包大小？
