<br><font size=2 face="Verdana">I use kernel 2.4.20,busybox 1.3.1,the NFS
server is V4.When I try to mount use <br>
<br>
mount -t nfs 10.25.16.130:/opt/Qtopia /opt/Qtopia <br>
<br>
Got error ,mount: RPC time out <br>
<br>
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: <br>

If it is the portmap and inetd's problem?</font>
<br><font size=2 face="Verdana">Following is some info:</font>
<br>
<br><font size=2 face="Verdana">In /etc/service <br>
sunrpc 111/tcp portmap <br>
sunrpc 111/udp portmap <br>
<br>
In /etc/inetd.conf <br>
#rstatd/1-3 dgram rpc/udp wait root /usr/sbin/tcpd rpc.rstatd <br>
#rusersd/2-3 dgram rpc/udp wait root /usr/sbin/tcpd rpc.rusersd <br>
</font>
<br><font size=2 face="Verdana">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????</font>
