Re: NFS connection dropped

Hi again,

I come back to "my" old thread, because the nfs is still not working 
correctly.

I have done this and the data _transfer_ works just fine. But, the 
problem is the mounting. Each time I try to mount the shared directory 
from the laptop (=client) by entering "mount 192.168.1.1:/<dir> /mnt" 
the client tries ... and tries ... and tries ... until I hit ctrl+c. 
The _server_ side just drops the attemps and, thus, refuses the 
connection between the two machines (nfs etc. _are_ enabled).

But, if I disable the server's firewall for a while I can - of course - 
mount the shared dir. And, once mounted, I can enable the server's 
firewall and transfer the data.

I haven't had much time for finding a solution for this problem, so I 
have used a USB-stick to transfer the date between my desktop and 
laptop. But I still would prefer a workaround solution for this 
problem, because some updates once downloaded on the server are far too 
big to fit on a USB stick... 

Kind regards,
Kimmo
