mounting shares on diff networks

[Vivek Malik]

hi,

i run a linux machine and want to mount shares available of other 
networks using smbmount.

so, i wanna mount all shares available on 10.140.*.* network whereas i 
am on 10.144.*.* network.

I run nmap on 10.140.*.* and find out all the computers with their 139 
port open.

I cant find out their netbios names.

How can i use smbmount to mount the share avaliable on say 10.140.2.90
using smbmount.

thanx,
vivek
