How to Configure User Equivalence (Key-Based Authentication) on Linux

-
Installation The SSH service should already be installed, but if it is not, install it from a Yum repository using the following command. # yum install openssh-server Turn on the SSH service and make sure it starts automatically on reboot. # service sshd start # chkconfig sshd on The SSH service is configured using the "/etc/ssh/sshd_config" file. Configuration changes have to be followed by a restart of the service. # service sshd restart # # or # service sshd reload Firewall The server must have the TCP port 22 open. This can be achieved by adding the following entry to the type of firewall script described  here . # Open port for NTP server. iptables -A INPUT -p tcp --dport 22 -j ACCEPT SELinux If you are using SELinux, you will need to consider the following points. The SELinux booleans associated with the SSH service are displayed using the  getsebool  command. # getsebool -a | grep ssh allow_ssh_keysign --> off fenced_can_ssh --> off ssh...

PostgreSQL - Access Oracle Database in PostgreSQL

-
          Today, organizations stores information(data) in different database systems. Each database system has a set of applications that run against it. This data is just bits and bytes on a file system - and only a database can turn the bits and bytes of data into business information. Integration and consolidation of such information(data) into one database system is often difficult. Because many of the applications that run against one database may not have an equivalent application that runs against another. To consolidate the information into one database system, we need a heterogeneous database connection.  In this post, I'll demo on how you may connect PostgreSQL to one of heterogeneous database Oracle using different methods. Below are few methods to make connection to Oracle database in PostgreSQL. Using ODBC Driver Using Foreign DataWrappers Using Oracle Call Interface(OCI) Driver Softwares used in demo(included download links): CentOS 7 64bit,...

How to Get Table Size, Database Size, Indexes Size, schema Size, Tablespace Size, column Size in PostgreSQL Database

-
In this post, I am sharing few important function for finding the size of database, table and index in PostgreSQL. Finding object size in postgresql database is very important and common. Is it very useful to know the exact size occupied by the object at the tablespace. The object size in the following scripts is in GB. The scripts have been formatted to work very easily with PUTTY SQL Editor. 1. Checking table size excluding table dependency: SELECT pg_size_pretty(pg_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 238 MB (1 row) 2. Checking table size including table dependency: SELECT pg_size_pretty(pg_total_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 268 MB (1 row) 3. Finding individual postgresql database size SELECT pg_size_pretty(pg_database_size('db_name')); 4. Finding individual table size for postgresql database -including dependency index: SELECT pg_size_pretty(pg_total_rel...

Postgres Database Patch

-
If you are used to patch Oracle databases you probably know how to use opatch to apply PSUs. How does PostgreSQL handle this? Do we need to patch the existing binaries to apply security fixes? The answer is: No.Lets say you want to patch PostgreSQL from version 10.5/11.3 to version 10.10/11.5. This is called minor version postgres upgrade or postgres patching Why need to patch postgresql server  ? Multiple SQL injection vulnerabilities have been discovered in PostgreSQL that could allow for arbitrary code execution. The vulnerabilities are the result of the application’s failure to sufficiently sanitize user-supplied input before using it in an SQL query. These vulnerabilities allow attackers with the CREATE permission (or Trigger permission in some tables) to exploit input sanitation vulnerabilities in the pg_upgrade and pg_dump functions. The CREATE permission is automatically given to new users on the public schema, and the public schema is the default schema used on the...
