How-to : Riverbed Service Platform (RSP) installation on Riverbed Steelhead 250H

-

Previous article about Riverbed covered RiOS upgrade process. In this post I will show how to install Riverbed Service Platform (RSP).

First let’s see how to get RSP image and what is RSP and how this can be used.

RSP can be downloaded from Riverbed Support page (https://support.riverbed.com/software/rsp.htm), where appropriate version for particular RiOS and Steelhead model can be downloaded.

Best source of detailed description will be RSP User’s Guide, so I did use it as source of information.

RSP offers branch-office-in-a-box services with the following benefits:

  • A VMware-based virtualization platform that provides the benefits of the most commonly deployed and advanced virtualization tool set
  • Support for running up to five different additional services simultaneously on a single Steelhead appliance, depending on the service and Steelhead appliance model
  • Support for more services and types of services, including in-band packages located in-line with optimization such as the Universal Threat Management (UTM) security services, proxy solutions such as video or network monitoring services, and improved support for out-of-band packages  such as Windows Active Directory, DNS and DHCP management software, and print services.
  • A comprehensive, integrated user interface that provides granular control of RSP, including setup, reporting, and the definition of the data flow between services

Tips & Tricks : MariaDB on CentOS : Installation and first configuration

-

In order to install MySQL/MariaDB database engine on CentOS follow these:

[root@localhost ~]# yum install mariadb-server
[root@localhost ~]# systemctl enable mariadb
[root@localhost ~]# systemctl start mariadb

[root@localhost ~]# mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] Y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.


Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n
 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
[root@localhost ~]#

Recommended is also to deploy phpMyAdmin, if you don’t have any issues with installing web server on same box as database.

That will simplify MySQL/MariaDB management.

Automating file transfer via SFTP i FTPS using WinSCP

-

Some time ago I received request to automate file transfer between FTP server and Development systems. Both, FTP server and Development system, are Windows-based. FTP server was running FTP over SSL only, so that automatically eliminated built-in Windows FTP command-line app. As I was using WinSCP in the past decided to do quick check if it is possible to use it in batch mode, so I can create script and run it on Windows Task Scheduler to automate whole process.

Code snippets : SQL : Backup and FTP transfer SQL Server database

-

Some time ago I had to transfer SQL Server databases from remote retail locations to central system. At that time whol einfrastructure was operating on Microsoft SQL server 2000 and link in remote locations was 128kb/s ISDN. At that time I thought that the best idea will be backup database to local hard disk on SQL server, RAR it and FTP compressed backup of SQL database to headquater. It did work quite well. So, below is a script I scheduled to be run as part of scheduled job defined on SQL Server Agent.

Before script will be used few things have to be customized:

  • location for database backups – @archive_path – default: F:\Backup
  • location of WinRAR application – @archive_cmd – default: C:\Program Files\WinRAR
  • IP address of FTP server – default: 192.168.10.120
  • Username and password for FTP user – default: dbupload/password
  • Folder on FTP server for backup upload – default: Site_Backup

As there might ba many remote sites uploading backups, each site can have different folder for data transfer.

Here is script to backup SQL Server database and trasfer backup to FTP server:

Tips & Tricks : CMD Batch parameters

-

Handful list of parameters possible to use in CMD scripts:

%~I         - expands %I removing any surrounding quotes ("")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
environment variable and expands %I to the
fully qualified name of the first one found.
If the environment variable name is not
defined or the file is not found by the
search, then this modifier expands to the
empty string

%~1         - expands %1 removing any surrounding quotes (")
%~f1        - expands %1 to a fully qualified path name
%~d1        - expands %1 to a drive letter only
%~p1        - expands %1 to a path only
%~n1        - expands %1 to a file name only
%~x1        - expands %1 to a file extension only
%~s1        - expanded path contains short names only
%~a1        - expands %1 to file attributes
%~t1        - expands %1 to date/time of file
%~z1        - expands %1 to size of file
%~$PATH:1   - searches the directories listed in the PATH
environment variable and expands %1 to the fully
qualified name of the first one found.  If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string

%~dp1       - expands %1 to a drive letter and path only
%~nx1       - expands %1 to a file name and extension only
%~dp$PATH:1 - searches the directories listed in the PATH
environment variable for %1 and expands to the
drive letter and path of the first one found.
%~ftza1     - expands %1 to a DIR like output line

Very useful for automated software installations for example.
