I am just having trouble to setup the NFS server. after reading the
HOWTO's it seems like the step that I have differnent is that when I
type in rpcinfo -p , it only reports back with 1 "nfs" with proto UDP
but not TCP? Could this be a problem? If so, how to get it up? Any
help will be greatly appreciated.
THx
Dan.

AIUI, nfs was intended as a stateless protocol to make crash recovery
easier, so it was only implemented in udp ... however locking
requirements introduced state and so might as well have tcp version.
So some other unices may already have a tcp version but I dont
*think* the current standard (?) linux nfsd version has tcp yet.
Hope you fix it soon,

1. ipchains/TCP/UDP, Why should I open UDP ports so that my TCP ports can work?
Hi,
I have set up firewall to accept some ports.
/sbin/ipchains -F input
/sbin/ipchains -P input ACCEPT
/sbin/ipchains -A input -p TCP -s 0/0 --dport ssh -j ACCEPT
/sbin/ipchains -A input -p UDP -s 0/0 --dport ssh -j ACCEPT
....
Then I want to lock down all other ports.
/sbin/ipchains -A input -p TCP -s ! 192.168.0.0/24 -j DENY
#??? what's wrong with this UDP ???
/sbin/ipchains -A input -p UDP -s ! 192.168.0.0/24 -j DENY
If I comment out the UDP line, I can ssh into firewall from outside.
If I don't comment out that line, I can no longer ssh into firewall from
outside.
Why should I open UDP ports so that my TCP ports can work?
Thanks for any help.

2. libproc.so not found (huh?)
3. Fw: NFSD over TCP: TCP broken?
9. mountd & nfsd can't register udp
10. can't get NFS to go ("nfsd: could not make a UDP socket"?)
11. Q: nfsd cant get tcp-socket
12. NFS DOS mount problems using nfsd or hclnfsd
