How to create user and configure password less ssh between OS users in Solaris 11

 

Hi, in this topic we learn how to created password less connectivity between two different Solaris Server with OS users:

For SSH Connectivity between Primary and Slave Node and with OS user creation in solaris 11:

apploci@ebsprodapp3:~$ id

uid=1007(apploci) gid=101(dba)

apploci@ebsprodapp3:~$ 

root@ebsprodapp4:~# mkdir /export/home/apploci

root@ebsprodapp4:~# touch /export/home/apploci/.profile

root@ebsprodapp4:~#

root@ebsprodapp4:~# chown -R apploci:dba /export/home/apploci

root@ebsprodapp4:~# chown  apploci:dba /export/home/apploci/.profile

root@ebsprodapp4:~# usermod -s /usr/bin/sh apploci

root@ebsprodapp4:~#

root@ebsprodapp4:~# passwd apploci

New Password:

Re-enter new Password:

passwd: password successfully changed for apploci

root@ebsprodapp4:~# 

root@ebsprodapp4:~# su - apploci

apploci@ebsprodapp4:~$ id

uid=1007(apploci) gid=101(dba)

apploci@ebsprodapp4:~$

ssh key gen to access form app4 to app3:

apploci@ebsprodapp3:~$ ssh-keygen

Generating public/private rsa key pair.

Enter file in which to save the key (/export/home/apploci/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /export/home/apploci/.ssh/id_rsa.

Your public key has been saved in /export/home/apploci/.ssh/id_rsa.pub.
