Open Source like US so Open to Any Solutions
Linux and Open Source Solutions
Linux Solutions' core services are based on designing and availing open source based software solutions. Through the use of Linux and other software of its kind, we are able to bring to you the best in terms of network servers and desktop solutions. We do offer Linux based servers that can perform the following functions and much more:
Firewall Servers
Real Time Firewall Solution
Most firewalls are purchased with network security in mind, but the type of security is rarely defined. Real Time´s network engineers work to understand how a network is used and then design the security to protect it. The design for the firewall can evolve as the company changes with security and services to meet your needs over the long term.
This evolutionary process doesn’t have to start with a small firewall that is solely dedicated to security. Other services and "add-ons" can be designed-in to address various network or company needs. For instance:
VPN - Secure remote access that encrypts data between the main office and a remote network or computer. More...
Bandwidth Monitoring - this add-on gives text & graphic information on how connectivity resources are used.
Web Caching - Can save up to 40% of the network’s bandwidth by caching frequently visited web sites.
Web Blocking - Allows the firewall to block traffic to many sites that are cause for concern or liability.
DMZ Network - A DMZ network is a second network behind the firewall used for services that need to be accessed directly from the Internet, such as mail or web services. The DMZ network is still protected by your firewall (so it's safer to run systems that do not have built-in firewall capabilities.) Basically, the private network can access the Internet and the services on the DMZ, but the servers on the DMZ and requests from the Internet cannot reach the private network.
Mail Servers
A mail server is a server dedicated to sending and receiving mail. A software application handles the sending of messages from client machines and the receipt of email from other servers.
Our Linux Mail Server package allows Real Time to implement the following optional features:
Spam Filtering
Virus Scanning
Email Forwarding
Auto-Answering
Mailing Lists
Virtual Domains
Web Based E-mail Access
This Linux Mail Server can be integrated into your current network and it is compatible with various email clients such as Thunderbird, Outlook and Outlook Express, Pegasus, Eudora and many others.
Mail Proxy Server
A mail proxy server is a stand-alone machine that is located in front of the actual email server. The mail proxy server is customized to provide any or all of the following services:
Web based email via IMAP
Virus scanning
File type blocking
File size blocking
Spam filtering
This way, the resource load is removed or reduced from the actual email server. The mail server can sit behind the firewall, protected on the private network.
An additional benefit is the existing email server can remain in service, which allows you to avoid a potentially large-scale end user migration to a new mail server and/or email client.
Virus scanning is available through ClamAV, an Open Source project, meaning no license or per user fees. File type and file size blocking helps reduce the chance of, or eliminate unwanted content from entering your network. The spam filter uses SpamAssassin with Bayesian filters for an improved scanning capability.
Web Servers
A Web Server provides the ability to host websites or take advantage of web based applications. In the simplest terms it is where a website that can be viewed through the Internet physically resides.
Real Time's Linux Web Server takes advantage of Apache, the most widely-used web server software according to a February 2006 Survey. More web servers use Apache than any other web server software, including Microsoft´s IIS software.
Real Time can provide the following features on a Linux Web Server:
128 bit Encryption
SSL 3.0
CGI support
Squid Web Cache and Proxy
Virtual Hosting
Web stats using Webalizer for Linux
We can also work with proprietary software for Linux like WebTrends or http-analyze
Java Servlets
MySQL
PHP
Real Time's Linux Web Server package can start around $1400. It includes software, and the configuration of Apache.
Network File Servers
Linux File Server
A file server differs from a personal computer (PC) in that the server is dedicated to storing files in a centralized location while permitting access to networked computers.
By having a file server, users can save work and have access to files without having to carry around a disk. Access privileges can be restricted to guests and registered users. Meanwhile a centralized location means once place to backup all files.
File servers allow networked computers to share files at their discretion. Servers also allow you to save work and have access to it without carrying around a disk. On a personal file server, you can restrict access privileges to guests and registered users.
This is the most common type of server in small businesses. A file server enables all files to be stored in a central location, which accommodates centralized backup strategies (one place to backup all files) and security implementation (depending on the operating system, individuals can be assigned different access rights to stored information).
Linux works great as a network file server. Linux includes software called samba that allows files on the server to be viewed and edited on any Windows 95/98/ME/2000/NT PC or Macintosh computer. In fact, you can connect to shares on the Linux file server, just as you would on your Windows NT/2000 file server. Everything will look the same and there are no per-user licenses required.
Benefits:
Files on the network server are backed up on a regular basis. If you inadvertently deleted an important file, it can be retrieved from the back up tape. In addition, if you have a hard drive failure the files you saved on the network server will not be affected.
Files can be shared with others. Several people may be working on a document. Storing the file in a shared directory allows each person to directly work on the document as needed.
If you use several PCs in the course of your work, files on the server are available from any local PC. So you have access to the files whether you are at your personal office PC or using a coworker's PC.
So, if everything is the same, why switch to a Linux file server? For the same reasons listed in our Why Linux? section. But to summarize:
Cost
We can install and configure a Linux File Server for as little as $1400 including configuration and software. If you can provide Linux compatible hardware, your savings might be even greater.
Performance
Our experience has shown that Linux will perform better as a file server than Windows NT or Windows 2000, even with Linux on older, slower hardware. And since Linux is designed to be a robust operating system (OS), hardware resources center on processing user requests instead of running the OS.
DNS Server
The Domain Name Server plays an important role in making Internet traffic possible. A DNS server is part of a global network of servers that translate host names, like www.netsysconsultants.com, into numerical IP (Internet Protocol) addresses, like 11.23.23.12, which computers on the Net use to communicate with each other. This allows us to use easy to memorize or intuitive URLs and e-mail addresses instead of a long string of numbers.
The advantage of having your own DNS server is it can process requests for traffic on your internal network without having to rely on another DNS server outside of your network. All the traffic is localized on your secure and internal network. Basically, this is a security feature because your LAN is essentially "hidden" from the outside world.
Real Time's DNS Servers run on Linux, giving them the stability and reliability everyone needs. It's also very cost effective because, like other Linux servers, a Linux DNS server can run on less expensive hardware than other operating systems.
As part of the installation, Real Time will also configure the server to your needs and specifications while keeping security as a top priority. Since it is built and designed in house, the server can be completely customized.
Print Server
A Print Server is a Computer that manages the printers on the network. All data to be printed is passed on to the Printer Server that allocates jobs to the printers on the network.
The print server is a sharing device designed to provide simple and efficient printer sharing. All users on the LAN, regardless of operating system or network protocol, will be able to share the printer(s) connected to the print server. By connecting the printers to a print server instead of a file server or workstation, it can reduce system loading, increase printing performance and allow different network protocols to be used simultaneously.
Network printing is a great way to save money on equipment. Print Serving can be set up to recognize one or several printers on the network for different jobs. It saves the cost of individual printers for each employee and allows work to be sent to the appropriate machine electronically, without having to run from office to office.
Real Time can set up Print Serving on the same machine that runs File Serving duties, but other configurations are possible too.
Fax Server
The software is designed to work in a network environment. Fax modems can be attached to a single machine on a network and clients can submit an outbound job from another computer on the network with related client software, which is lightweight and easy to port.
HylaFAX™ is very robust and reliable. The fax server is designed to guard against unexpected issues related to the software, hardware or actual transmissions. The application was also built to give users confidence- it uses an intelligent scheduling for sending and optimizing retry attempts. Jobs are either completed successfully or the submitter is notified of what happened. HylaFAX™ supports multiple modems and various traffic loads, so it can covers the needs of different sized networks.
Pricing varies depending on the service and hardware requirements. Please contact Real Time directly at +971-4-3389711 for more information.
