Here are 10 of the best free tools / packages for troubleshooting system issues. These tools should help you as an admin to fix the problem or identify the root cause more quickly. You can either use these tools yourself or provide them to a user who is experiencing the issue, for them to gather the information needed.
As part of the troubleshooting process, it is helpful to know as much information as you can about the machine where the problem resides to assist in finding a solution more quickly. WinAudit scans your computer and gathers a whole raft of information about Installed Software, TCP/IP settings, Drives, Error Logs, etc.
As for enterprises and SMBs, there are a number of open-source software that successfully replaced their license-based counterparts: OpernCart (online shopping platform), SuiteCRM (useful for managing customer info), Helpy (self-service support), Mailman (management tool for email lists), WordPress (blogging), Daawarpper (data visualization), Gimp (powerful image editor), LibreOffice (perfect and free alternative to Microsoft Office), and the list goes on.
Things change a bit when it comes to deploying freeware on enterprise machines. Of course, some shareware can handle some of the routine tasks. For instance, ePrompter is a great and hassle-free alternative to Microsoft Outlook or some other desktop-based email management tool. Even TeamViewer, the (over)glorified remote computer control tool is free and can be used to accomplish very simple tasks.
As you know, outdated and unpatched software can be used by malicious hackers to circumvent your antivirus\antimalware solution. Since freeware does not receive regular security patches, it can become an entry point for malware.
Another top-rated antivirus software is Bitdefender. This software provides excellent virus protection without being heavy on your computer. Other features include safety when chatting online in popular social networks, highly rated virus detection and a function which protects mobiles from physical theft. It scans networks quickly and also operates through a VPN. To top it off, Bitdefender offers a basic free version with some impressive features.
If a piece of software is open source, it comes with an open source license which grants the user the right to use the product as they see fit. This license removes all the usual restrictions which come with copyright law, and are therefore sometimes referred to as copyleft licenses. The freedom for users granted by this license covers a range of things, primarily grouped into three categories.
The terms free license software and open source software often appear interchangeably to refer to the same licenses and, usually, software. The difference is nuanced and refers to a slightly different approach or philosophy to building software. To put an end to the discrepancy over what is a negligible difference, you might see the term FOSS (free and open-source software), created to cover all bases. You can find more on this in the history of proprietary software.
Where open source and free license software intersect with proprietary software is in the license attached to the free license software. This intersection mostly affects the rules around the distribution of modified open source software. The open source licenses include:
Where did proprietary software come from? When software was in its infancy in the 1960s, computers were unrecognisable from what they are today. They were huge machines that took up an entire room, which had to be specially cooled. The computers were used primarily for bulk data processing, and as they were so expensive, were often leased to corporate customers rather than sold. All software installed on the computers were supplied by the manufacturers, too, and they provided the source code.
In the early 1980s, some developers wanted to preserve the freedom and collaboration associated with early software development. To return to this model, Richard Stallman set up the GNU Project in 1983 to keep software free. He invented copyleft, producing the GNU General Public License which removed all the copyright restrictions. This return to an open model eventually led on to the open source software movement to protect peer development.
Shareware refers to proprietary software which is available to users for free under certain conditions. Software owners who distribute shareware often also have a commercial version of the same product, in which case the shareware would have limited functions compared with the paid version. Other shareware might represent the full paid product, but has a very limited period of use, as is the case with many free trials. The idea behind shareware is to give users a chance to test out the product before they invest in a license.
Free and open-source software (FOSS) is a term used to refer to groups of software consisting of both free software and open-source software[a] where anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software.[3] This is in contrast to proprietary software, where the software is under restrictive copyright licensing and the source code is usually hidden from the users.
FOSS maintains the software user's civil liberty rights (see the Four Essential Freedoms, below). Other benefits of using FOSS can include decreased software costs, increased security and stability (especially in regard to malware), protecting privacy, education, and giving users more control over their own hardware. Free and open-source operating systems such as Linux and descendants of BSD are widely utilized today, powering millions of servers, desktops, smartphones (e.g., Android), and other devices.[4][5] Free-software licenses and open-source licenses are used by many software packages. The free software movement and the open-source software movement are online social movements behind widespread production and adoption of FOSS, with the former preferring to use the terms FLOSS or free/libre.
Although there is almost a complete overlap between free-software licenses and open-source-software licenses, there is a strong philosophical disagreement between the advocates of these two positions. The terminology of FOSS or "Free and Open-source software" was created to be a neutral on these philosophical disagreements between the FSF and OSI and have a single unified term that could refer to both concepts.[7]
Richard Stallman's Free Software Definition, adopted by the Free Software Foundation (FSF), defines free software as a matter of liberty not price,[8][9] and it upholds the Four Essential Freedoms. The earliest-known publication of the definition of his free-software idea was in the February 1986 edition[10] of the FSF's now-discontinued GNU's Bulletin publication. The canonical source for the document is in the philosophy section of the GNU Project website. As of August 2017, it is published in 40 languages.[11]
To meet the definition of "free software", the FSF requires the software's licensing respect the civil liberties / human rights of what the FSF calls the software user's "Four Essential Freedoms".[12]
The Open Source Definition is used by the Open Source Initiative (OSI) to determine whether a software license qualifies for the organization's insignia for open-source software. The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens.[13][14] Perens did not base his writing on the Four Essential Freedoms of free software from the Free Software Foundation, which were only later available on the web.[15] Perens subsequently stated that he felt Eric Raymond's promotion of open-source unfairly overshadowed the Free Software Foundation's efforts and reaffirmed his support for free software.[16] In the following 2000s, he spoke about open source again.[17][18]
From the 1950s and on through the 1980s, it was common for computer users to have the source code for all programs they used, and the permission and ability to modify it for their own use. Software, including source code, was commonly shared by individuals who used computers, often as public domain software[19] (FOSS is not the same as public domain software, as public domain software does not contain copyrights[20]). Most companies had a business model based on hardware sales, and provided or bundled software with hardware, free of charge.[21]
The Linux kernel, created by Linus Torvalds, was released as freely modifiable source code in 1991. Initially, Linux was not released under either a Free software or an Open-source software license. However, with version 0.12 in February 1992, he relicensed the project under the GNU General Public License.[30]
While the Open Source Initiative sought to encourage the use of the new term and evangelize the principles it adhered to, commercial software vendors found themselves increasingly threatened by the concept of freely distributed software and universal access to an application's source code. A Microsoft executive publicly stated in 2001 that "Open-source is an intellectual property destroyer. I can't imagine something that could be worse than this for the software business and the intellectual-property business."[32] This view perfectly summarizes the initial response to FOSS by some software corporations.[citation needed] For many years FOSS played a niche role outside of the mainstream of private software development. However the success of FOSS Operating Systems such as Linux, BSD and the companies based on FOSS such as Red Hat, has changed the software industry's attitude and there has been a dramatic shift in the corporate philosophy concerning its development.[33]
According to Yochai Benkler, Jack N. and Lillian R. Berkman Professor for Entrepreneurial Legal Studies at Harvard Law School, free software is the most visible part of a new economy of commons-based peer production of information, knowledge, and culture. As examples, he cites a variety of FOSS projects, including both free software and open-source.[115] 2b1af7f3a8
