In order to enable SSH access to Cisco Nexus 1000v (if it’s not enabled yet) followign commands have to be issues from Console or Telnet connection:

Little issue with OpenSSL for Windows came out recently when I tried to create certificate request. Just after installation when tried to generate cert request got error message:
WARNING: can't open config file: /usr/local/ssl/openssl.cnf Unable to load config info from /usr/local/ssl/openssl.cnf
Reason was that by default OpenSSL couldn’t find configuration file (even if it was located in same folder as excutable file).
So, to fix it just set environmental variable with information where openssl.cfg file is located:
You can consider adding this to system environmental variables.
After installation PostgreSQL is listening on localhost only. To change that adjustment has to be done in postgresql.conf.
After I instaled PostgreSQL on Amazon Linux AMI, first thing after database server was up and running I start thinking how to create user with administrative privileges, so I can access it using some management applications.
So, here is how to create superuser and set password, which will allow to access PostgreSQL using admin tools.
