it works for the others machine but i juz try to use it on the new machine, it give me error

bash: /home/pc2/.ssh/authorized_keys : No such file or directory

can anyone tell me why this happened ? thanks in advance for sorry for the ignorance

You're supposed to copy it to the remote machine, not the local one.

thanks for the reply

based on this link : https://blogs.oracle.com/jkini/entry/how_to_scp_scp_and

It suposed to transfer the id_rsa.pub file to remote machine and on the remote machine , login as the remote user which you plan to use when you run scp, ssh.

Then copy the contents of id_rsa.pub to ~/.ssh/authorized_keys

i have follow the steps , transfer to the remote machine . it works to other machine but not this 1 ..

Can tell me how to solve this ?? thanks in advance
