thanx for the help. it was an oversight on my part. my apologies to the
group. i had entered ip addresses incorrectly.
subsequently, i have edited /etc/network/interfaces by hand and set the
things right - by hand! i used vi for the first time and was amazed at the
facilities it provides. all *i mean it* win editors look pale compared to vi!
and all seems well now. however, i wanted to know if there is a tool/ utility
to do what i did by hand.
further i wanted to know if there are any other places where i need to change
ip address my machine and gateway other than what i have already done.
i also will like to know what does entry 'network' in /etc/network/interfaces
mean and where does one change dns server entries?
last but not the least - how do i access my lan resources? files on other pcs
and printers connected to them? in windows i can do it!
thanx in advance,
sandip
