(src1) (src2) troubleshooting

on the server side

# yum -y install openssh-server openssh-clients
# service sshd start

on the client side:

$ ssh-keygen -t rsa  
$ ssh-copy-id -i ~/.ssh/id_rsa.pub admin@192.168.1.8
$ ssh-add
$ ssh root@192.168.1.8

on the server side again:
edit /etc/ssh/sshd_config:

AuthorizedKeysFile  /etc/ssh/%u/authorized_keys

and do:

# rmtuser=admin
# mkdir -p /etc/ssh/${rmtuser}
# cp /home/${rmtuser}/.ssh/authorized_keys /etc/ssh/${rmtuser}/
# chown -R ${rmtuser}:${rmtuser} /etc/ssh/${rmtuser} -R
# chmod 755 /etc/ssh/${rmtuser}
# chmod 644 /etc/ssh/${rmtuser}/authorized_keys
# service sshd restart

on the client side:

$ ssh admin@192.168.1.8

# usermod -a -G dialout plc

test post access:

# yum install setserial
$ setserial -g /dev/ttyS0
