bypass password authentication for sftp in unix

I am using solaris unix 8.2 version. I want to bypass password authentication for sftp. Can you please give some ideas on this. thanks.Regards.

You can go for ssh key exchange for the ID you will be using for sftp.

Hi,

Thanks for your mail. Are you talking about this script .give me reply.thanks,regards.

a) Logged in Server A with user Id 'informat' and corresponding passowrd.Home directory is '/opt/informatica'

b) Created the keys in server 'A' with the following command.
/user/local/bin/ssh-keygen -t rsa

c) Copied the public key in id_rsa.pub file under /opt/informatica/.ssh directory of server 'A'

d) Copied the 'id_rsa.pub' file to 'authorized_key' file in /opt/informatica/.ssh directory in server 'B'

e) Grant 777 privileges to authorized_key file in server 'B'

f) Logged into server 'A' with 'informat' user ID

g) Executed the sftp command for server B
sftp informar@B

You're right!:b:

We have to run sftp client at unix end right. any suggestion on this client sftp suggestion. there are 2 steps only right.
install sftp client in unix end
do the password authentication.

other than that any steps need to do unix end to use sftp to connect outside. please give me reply .thanks.regards.
