Password less SSH login to different server

Hi,

It is continuation with my other thread, The issue i found is U1 does not set properly for password less ssh.

for setting up password less ssh i followed the following steps

1. ssh-keygen
2. ssh-copy-id -i ~/.ssh/id_rsa.pub hostname
3. /usr/bin/ssh -t -t U1@hostname sample.sh

it is asking password. I tried the same steps for different users and it is working fine.

Please help me to troubleshoot this issue.

If you want to connect to remote server from your local without using passwords do the following steps:
1. Generate the ssh keys on your local using ssh-keygen.
2. Copy the generated pubic key (by default id_rsa.pub, if you ran ssh-keygen without any options) and place it in the ~U/.ssh/authorized_keys of your remote. I am not sure how to use ssh-copy-id, but you can try using the below code(run it from your local):
Code:
locPubKey=$(cat ~/.ssh/id_rsa.pub)
ssh U@remote "echo "$locPubKey" >> ~/.ssh/authorized_keys"

3. Now try connecting to your local using
Code:
ssh U@remote

hi

ssh-copy-id does the same. Copy the content from file
.ssh/id_rsa.pub to authorized_keys file.

In my case, it works for one ID and not working for another ID.
