Hi,
I'm tring to setup a PXE environment. The host is my home server runing slackware 11.0. I cant get NFS use tcp. I don't even know wheter it's possible or not.
I need tcp because I tried to install ubuntu9.10 on a client which insist on tcp using nfs.
Any ideas?
To do this, query the portmapper with the command rpcinfo -p to find out what
services it is providing. You should get something like this:
+---------------------------------------------------------------------------+
| program vers proto port |
| 100000 2 tcp 111 portmapper |
| 100000 2 udp 111 portmapper |
| 100011 1 udp 749 rquotad |
| 100011 2 udp 749 rquotad |
| 100005 1 udp 759 mountd |
| 100005 1 tcp 761 mountd |
| 100005 2 udp 764 mountd |
| 100005 2 tcp 766 mountd |
| 100005 3 udp 769 mountd |
| 100005 3 tcp 771 mountd |
| 100003 2 udp 2049 nfs |
| 100003 3 udp 2049 nfs |
| 300019 1 tcp 830 amd |
| 300019 1 udp 831 amd |
| 100024 1 udp 944 status |
| 100024 1 tcp 946 status |
| 100021 1 udp 1042 nlockmgr |
| 100021 3 udp 1042 nlockmgr |
| 100021 4 udp 1042 nlockmgr |
| 100021 1 tcp 1629 nlockmgr |
| 100021 3 tcp 1629 nlockmgr |
| 100021 4 tcp 1629 nlockmgr |

This says that we have NFS versions 2 and 3, rpc.statd version 1, network
lock manager (the service name for rpc.lockd) versions 1, 3, and 4. There are
also different service listings depending on whether NFS is travelling over
TCP or UDP. Linux systems use UDP by default unless TCP is explicitly
requested; however other OSes such as Solaris default to TCP.

5.4. NFS over TCP
A new feature, available for both 2.4 and 2.5 kernels but not yet integrated
into the mainstream kernel at the time of this writing, is NFS over TCP.
Thank you, allend,
I made a fool of myself because I've read this howto, but I don't know why I believed I used 2.6 kernel. Now I checked and realized that my kernel version is 2.4.33.3.
Unfortunately on this hardware slacware13 installation goes to guru meditation.
Anyway, I mark this thread solved thanking again your posting.
