I would uninstall network manager if you want to use static addressing. 
OTOH I would always prefer DHCP, even if the DHCP server is set up to 
always give the same address to individual interfaces.

Are both machines on the same subnet? If you are using addresses in the 
192.168.x.y address range, the default subnet mask of 
limits the subnet to the y part of the addresses, i.e. the addresses may 
only be different at the last number.

But how are your machines connected? Is there a direct cable between the 
machines or is there a hub / switch / router between the machines?

This warning is not a real problem. Read "man exports" for the meaning of 
the options but you should at least be able to mount the directory. 
Anyway, first make the machines see each other, i.e. ping must work.

Depends on what you call "share files". If you want to mount directories, 
I think NFS is what you want. Samba is only useful if you want to share 
files with Windows machines.
