Here is my problem: I would like to perform scp command after ssh to remote server without typing any passwords. I describe my steps. My first steps were:

ssh-keygen -t rsa and

local@host$ ssh-copy-id -i /root/.ssh/id_rsa.pub remote@host on local machine

Then I did the same on remote machine:

ssh-keygen -t rsa and

remote@host$ ssh-copy-id -i /root/.ssh/id_rsa.pub local@host

After all described above I could do ssh on both machines without typing any password. I could perform scp command on remote machine like scp /home/remote/info.txt.gz local@host:/root/ and everything worked perfectly.

Then I tried to make a script with some actions described below and the last step in my script was scp command that did not work as I expected.

#!bin/bash remote_user=$1 remote_host=$2 local_user=$3 local_host=$4 echo "Testing connection to ${host}..." ssh -n -o NumberOfPasswordPrompts=0 ${remote_user}@${remote_host} if [ $? -ne 0 ]; then echo "FATAL: You don't have passwordless ssh working." echo "Try running ssh-keygen" exit 1 fi echo "Okey. Starting the process." ssh ${remote_user}@${remote_host} netstat -tulpn > /home/${remote_user}/info.txt;uptime |awk '{ print $3 }' >> /home/${remote_user}/info.txt; if [ $? -ne 0 ]; then echo "An error occurred." else echo "File is ready for gzipping!" fi gzip /home/${remote_user}/info.txt if [ $? -ne 0 ]; then echo "file was not archived" else echo "Archive is ready!" fi echo "Starting copy archive from ${remote_host} to ${local_host}" scp /home/${remote_user}/info.txt.gz ${local_user}@${local_host}:/root/ if [ $? -ne 0 ]; then echo "Error while transferring!" else echo "Copy has been transferred successfully!" fi 

Scp command asked me for password o_O.

When I did all steps in script manually everything worked perfectly but in script scp demanded password. I read a lot through stackexchange and found this answer Using an already established SSH channel. This answer requires Open SSH but my problem can be resolved manually via SSH as I said but in script it did not work. What am I going to do to make scp works without password?
