The Importance Of Remote Network Access For Businesses

It is not unusual for a business to own network equipment dispersed in various geographical areas that they need to keep a close eye on. Ensuring that all routers, servers and the rest of the network gear are running 24/7 well is mandatory for the well-being of all operations. However, this can be challenging for the IT department, especially when your staff is out of the office most of the time as part of the modern-day remote work trend. Some of your employees might be in the field most of the time, while others might choose to work from home. It is also possible for the actual IT staff to be working from a remote location. This is a scenario that is gaining more and more popularity nowadays, and it requires smooth access to a network for proper monitoring. Unfortunately, not all managers are able to provide their IT personnel with the network access they need from a remote location. The risk of security breaches continues to be one of the main obstacles in the way of remote network management practices. However, remote monitoring comes with a series of undeniable advantages we are going to introduce to you within these next few lines.

Keep An Eye On Your Remote Officesnetwork access

If you are running a business with several locations and offices spread all across the country/state/city, you could use remote network software for monitoring purposes and effectively manage all of your devices. Managing a restaurant chain with different local diners will be done a lot easier with the help of remote monitoring tools. You should be able to keep an eye on the performance of all the devices in all of your locations without too big of an effort. This software should also inform you whenever there are any performance issues you need to address.

It is possible to use tracking devices for network maps and make the difference between your various offices. This way, whenever a device will break down in one of your office or branch locations, you will be able to immediately access and fix it without having to physically travel to the respective location. You will not only be saving a lot of precious time, but you will also get to spend less on your network maintenance and troubleshooting.

Your Remote IT Staff Can Monitor The Network In Real-Time

In case your IT staff is the one that is located in one or several remote offices/areas, remote network access can help them remotely access all the performance data and parameters in real-time. With the help of network maps, a network engineer can see everything you are seeing on your computer and save time and energy on the actual troubleshoot, whenever there is a problem. You can focus on your management activities and let the pros do their job without too much or any interference in your regular schedule and tasks.

Since the IT staff you have hired does not necessarily need to be present in your offices on a continuous basis, you will enjoy a lot more freedom of movement in terms of work completion. You can choose to do your tasks from a coffee shop or from home and rely on remote network access to check the status of all of your devices using your laptop or smartphone.

Remote Network Access Can Boost Overall Security

If you are one of those managers who are particularly concerned about the risk of security attacks in relation to remote access to your network, you should be happy to learn there are good solutions for you. The use of encrypted authentication and customized user access will contribute to the lowering of this risk. It is also a good idea to use patches for security breaches and threats and get notifications whenever a new patch is released so you can take advantage of its improved benefits as soon as you can.

Mysql crash problems on EC2 AWS micro instance

If you have the default mysql config probably you’ll have some crash problems after a while running the instance.

I’m running a micro instance, with Ubuntu 12.04 and default mysql installation.

I’ve this logs reports:

[Note] Plugin 'FEDERATED' is disabled.
InnoDB: The InnoDB memory heap is disabled
InnoDB: Mutexes and rw_locks use GCC atomic builtins
InnoDB: Compressed tables use zlib 1.2.7
InnoDB: Using Linux native AIO
InnoDB: Initializing buffer pool, size = 128.0M
InnoDB: mmap(137363456 bytes) failed; errno 12
InnoDB: Completed initialization of buffer pool
InnoDB: Fatal error: cannot allocate memory for the buffer pool
[ERROR] Plugin 'InnoDB' init function returned error.
[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
[ERROR] Unknown/unsupported storage engine: InnoDB
[ERROR] Aborting

[Note] /usr/sbin/mysqld: Shutdown complete

 

To solve it you need to add some lines on the /etc/mysql/my.cnf file after the [mysql] line:

innodb_buffer_pool_size = 40M
key_buffer_size=10M
max_connections=5

Also it’s recommended to run a repair table on each of your databases after changing the mysql settings and restart the mysqld service.

How to backup MySQL database from the command line

Backup your MySQL database to an sql file with your command line. Using native mysql client and tools you can perform all the backup and restore operations you need.

First you need to have installed the command line tools, in this case mysqldump.

$ mysqldump --opt -u [uname] -p [dbname] > [backupfile.sql]
  • [uname] Your database username
  • [pass] The password for your database (note there is no space between -p and the password)
  • [dbname] The name of your database
  • [backupfile.sql] The filename for your database backup
  • [–opt] The mysqldump option

Example if you have a database called wordpress_blog you only have to do this:

$ mysqldump --opt -u root -p wordpress_blog > wordpress_blog_bk.sql

If you want to backup all the databases in only one sql file you can use –all-databases option

$ mysqldump -u root -p --all-databases > alldb_backup.sql
