ssh - password prompt keep on coming on the console -

i wrote below command, copy id_dsa.pub file other server part of auto login feature. every time below message coming on console:

spawn scp -o stricthostkeychecking=no /opt/mgtservices/.ssh/id_dsa.pub root@12.43.22.47:/root/.ssh/id_dsa.pub password:  password:  

below script wrote this:

function sshkeygenerate() {     if ! [ -f $home/.ssh/id_dsa.pub ] ;then expect -c"   spawn ssh-keygen -t dsa -f $home/.ssh/id_dsa                  expect y/n { send y\r ; exp_continue } expect passphrase): { send \r ; exp_continue}expect again: { send \r ; exp_continue}                  spawn chmod 700 $home/.ssh && chmod 700 $home/.ssh/*                  exit "     fi      expect -c"spawn scp -o stricthostkeychecking=no $home/.ssh/id_dsa.pub  root"@"12.43.22.47:/root/.ssh/id_dsa.pub         expect *assword: { send $rootpwd\r }expect yes/no { send yes\r ; exp_continue }         spawn ssh -o  stricthostkeychecking=no root"@"12.43.22.47 \"chmod 755 /root/.ssh/authorized_keys\"         expect *assword: { send $rootpwd\r }expect yes/no { send yes\r ; exp_continue }         spawn ssh -o stricthostkeychecking=no root"@"12.43.22.47 \"cat /root/.ssh/id_dsa.pub >> /root/.ssh/authorized_keys\"     expect *assword: { send $rootpwd\r }expect  yes/no { send yes\r; exp_continue }     sleep 1     exit" } 

you should first create passwordless ssh destination server, won't need enter password while scp.

assuming 192.168.0.11 destination machine:

1) ssh-keygen -t rsa

2) ssh sheena@192.168.0.11 mkdir -p .ssh

3) cat .ssh/id_rsa.pub | ssh sheena@192.168.0.11 'cat >> .ssh/authorized_keys'

4) ssh sheena@192.168.0.11 "chmod 700 .ssh; chmod 640 .ssh/authorized_keys"
