[vox-tech] NFS:mount RPC timed out

[xiao.liang@cMAPSn.alps.com]

I use kernel 2.4.20,busybox 1.3.1,the NFS
server is V4.When I try to mount use 

mount -t nfs 10.25.16.130:/opt/Qtopia /opt/Qtopia 

Got error ,mount: RPC time out 

When I use ethreal on both the server and client side , found that the
server have sent SYN,ACK back to client with the TCP connection, but the
client just do not respond. I use portmap and also inetd. The tcpdump log
is look like this:

If it is the portmap and inetd's problem?
Following is some info:

In /etc/service 
sunrpc 111/tcp portmap 
sunrpc 111/udp portmap 

In /etc/inetd.conf 
#rstatd/1-3 dgram rpc/udp wait root /usr/sbin/tcpd rpc.rstatd 
#rusersd/2-3 dgram rpc/udp wait root /usr/sbin/tcpd rpc.rusersd 

Client use a random tcp port number to
connect with server:111, then who will look after the SYN,ACK packet sent
back by server, the inetd? Should I add a line in inetd.conf like "794
   stream  tcp   nowait root  portmap" ,
but it is a ramdom port number?! Or should there be a tcpd or sth run on
my board????

Ask for help!!!!!

ps :

/usr/sbin/inetd 
/sbin/portmap
