请问，关于skyeye中的nfs mount
我装的是skyeye-v0.2b3.tgz， uclinux4skyeye-v0.2.3， uClinux-dist-20030305.直接将uclinux4skyeye-v0.2.3覆盖uClinux-dist中相应目录。然后按照安装要求2a安装的。进入uclinux之后，设置ip为10.0.0.2.再开一个终端，可以用ifconfig看到tap0为10.0.0.1, 然后测试ping 10.0.0.2和 telnet都是正常的。
但是，我在主机端配好nfs服务器，保证可用。（exports内容为：/target *(rw,no_root_squash,no_all_squash) ），
在uclinux中执行mount -t nfs 10.0.0.1:/target /tmp
mount -t nfs 10.0.0.1:/target /tmp
nfs warning: mount version older than kernel
NFS: mount program didn't pass remote address!
mount: Mounting 10.0.0.1:/target on /tmp failed: Invalid argument
pid 21: failed 256
请问是什么原因？？ 这个问题我也遇到了，在 redhat 9 上面， nfs 在本机上 mount -t nfs 可以成功，但是其他机器就不行，运行出错信息为：
mount -t nfs 166.111.xx.xx:/tmp /tmp
mount: RPC：远程系统错误 - 拒绝连接
用 showmount 也不行： /usr/sbin/showmount -e 166.111.xx.xx
mount clntudp_create: RPC: Port mapper failure - RPC: Unable to receive
但是 portmap 和 nfs 都起了，在本机上执行： /usr/sbin/rpcinfo -p 166.111.xx.xx

看了文章好像说要 加载 plip ，试了一下还是 mount不上。

如果谁能在 rh9 上跑起来，记得来回复一下这个帖子，谢谢！ 原因已经找到，是 iptables 的问题。
# iptables --list

用 iptables -F 即可解决。
# iptables -F
# iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain RH-Lokkit-0-50-INPUT (0 references)
target prot opt source destination
此时在远程主机上mount -t nfs xxx.xxx.xxx.xxx:/tmp /tmp 就可以了。
