Setting Up no-password SSH |
| 
Sometime we had a script for running process in remote machine. In this case, we need to setup SSH with no-password to remote another machine and run process what we need. The basic idea is, however, that in the cryptosystem that ssh uses (RSA or/and DSA) the encription and decription are done using diferent keys Basically, what the user (client) needs is to generate a public/private key pair. The server will know the public key, but only the client will know the private key.

Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address.
