How-to : Access BlackBerry PlayBook via SSH

-

So, I was wondering how to access my PlayBook using SSH. It would be really convinient to access it from laptop, browse files, etc. I did poke around on Internet and finally identified solution how to SSH to PlayBook 🙂 For now only as a normal user and working towards getting root access (I guess Dingleberry will be helpful at some stage) 🙂

For now let’s have a look into details of accessing PlayBook via SSH. for that I will use:

  • BlackBerry Tablet SDK 2.0.0 – available for free on BlackBerry web page here. There might be newer version available by now.
  • PuTTY – I guess most popular free terminal emulator for SSH, Telnet and Serial connections, available here. From that package PuTTY.exe and PuTTYgen.exe will be required.

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 : CentOS firewalld : open port

-

Once you install CentOS 7, by default firewalld will block almost all network traffic.

In order to open ports for certain services you can easily reconfigure firewall using firewall-cmd command.

[root@localhost firewalld]# firewall-cmd --get-active-zones
public
  interfaces: eno16777728
[root@localhost firewalld]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@localhost firewalld]# firewall-cmd --reload
success

Example contains port 80, however you can open any port using same method.
It is worth to check zones configured on your machine and make sure you open port in proper zone where service should be enabled.

Config snippets : Setting NTP server on Cisco IOS device

-

Quick config snippet to setup external NTP server to synchronize time on Cisco IOS router.

labisr-01(config)#ip name-server 4.2.2.2
labisr-01(config)#ntp server 0.europe.pool.ntp.org
Translating "0.europe.pool.ntp.org"...domain server (4.2.2.2) [OK]
labisr-01(config)#clock timezone GMT 0
labisr-01(config)#
Please note that first I setup nameserver on router to be able to resolve NTP server FQDN.

Once NTP server is set we can check status of it:

labisr-01#sh ntp associations
