how to connect to a pc with rsh/ssh

g_ramesh · 07-19-2010, 01:09 PM

Hi

two pcs with following ip add are there
pc1 - 10.1.1.1
pc2 - 10.9.16.1

I said to my friend that both can not talk to each other as it is,
but have another NIC and give the ip in the range 10.9.16.2 then only
we can use rsh/ssh to log into the pc2. Is it correct or is there a better way ?

Well this is clearly nothing to do with ssh or rsh. You need some form of IP route between the two devices, and suitable routing entries and all applicable devices to reach each other. Assuming you have a /24 mask on each machine they will not be able to talk without some form of router in the middle.

thanks for your reply. Is it not possible to talk to each other without a router? I gave rsh/ssh as an example only to log into each other.

@g_ramesh: If you're so inclined, and really want to learn, read The TCP/IP Guide.

Short answer is - you already have your answer. (Unless you're on a subnet using an /8 netmask, which would be odd.)

tcp/ip works like it does for VERY VERY good reasons.
