hi,
to ssh login i give the command..
root@localhost~] # ssh ip_add
it allows me to login on a remote machine if i know the password, but i work on wireless network so the ip keeps on changing for the remote machine, how can i access that machine with some unique name , that does not changes.i have RHEL-5 on my machine

pls hel

you can assign the machine you are logging into a static IP address if you control the router or DHCP server.

Barring that, look into Dynamic DNS as a solution. There are various services that handle this for you, but not on internal IP addresses. You would have to look into some sort of personal dynamic DNS for that.

The simplest solution would be to hard set the IP address of your Linux host and then perhaps give it a short name on your client via the /etc/hosts file on a *NIX machine or:
C:\windows\system32\drivers\etc\hosts on a windows 2000/XP machine.

/etc/hosts shows following.....
#do not remove following lines or various programs
#that require network functionality fail
127.0.0.1 localhost.localdomain localhost mawandia
::1 localhost6.localdomain6 localhost6



what changes must i bring to it.........and how to hard set the ip
(any ways thanks for replyin i m really new to linux)

The /etc/hosts part is the LAST part, and not nearly important.

You have 2 machines.

You have your Linux host and your client (which can be anything for this).


The questions come up as:

Do you control the network that the machines are a part of?
Could you install services or change configurations on either of the machines?
How elegant do you want this to be?
