I got this working between two BL computers last year (?) and reported in 
the archives.  I compiled my own 2.4.31 kernel with the proper support for 
ntfs and rpc, which needs three modules, or use BL3 'big' kernel without 
the modules.

I have /etc/exports which I had to create myself, that reads:

/ 192.168.1.1(rw,no-root-squash)

I have this on both my computers - probably only one needs it.
The server?

Use the BL3 'big' kernel (or my 2.4.31 kernel).
Insert network modules (or run pcmcia start on a laptop).

I made two scripts to set up the two computers.

On the computer whose files you want to access (server?)

ifconfig eth0 192.168.1.1
rpc.portmap
rpc.mountd
rpc.nfsd

On the computer where you want to mount files from the other one:

ifconfig eth0 192.168.1.2
insmod sunrpc   (modules not needed by BL3 big kernel)
insmod lockd
insmod nfsd
rpc.portmap
mount -t nfs 192.168.1.1: / /mnt

The files from the first computer should be accessible now from /mnt on 
the second computer.

No idea.  I read that ssh is much more secure than the above approach.
What does rsh do?

See the archives (BL + firewall?).  I used one computer as a modem-type 
gateway.  Steven's very simple (1 or 2 line) setup worked fine, with 
firewall, over a system set up as above.  Is the firewall so other 
computers besides mine cannot access the computer which is connected to 
the internet?

I found it simpler to run dropbear on the computer connected to the 
internet, and ssh (or dbclient) on the other one, which is supposed to be 
more secure than rpc (but maybe with firewall rpc is okay).  I posted 
glibc and uclibc packages for dropbear/dbclient (ssh equivalent).

This method did not provide nfs file sharing, but I could copy files 
between computers with scp or ftp or wget/browser (run dropbear, pure-ftpd 
or mini-httpd/httpd on one computer).
