Novell Netware

The system administrator can determine that a program or file is shared or unshared. If a file not shareable different users archive viewable mode only reading but unable writable while another user in use mode reading or writing.

NetWare requires access to network directories through specific network drives. Network drives to directories on the network and not physical disk drives. Each workstation can be assigned 21 logical drive letters (F through Z). This means that DOS uses the default letters A to E.

Units NetWare search allow operating system locate files programs different directories directory predefined corresponding. Placing used programs universally directories public access then map them one unit search the fileserver locates programs requested even if not found current directory whence becomes application. Novell NetWare provides the most important safety systems on the market, and providing security of file servers in four different ways: check procedure, mandated rights, rights in the directory and file attributes. NetWare 4.x NetWare 4.x is a network operating system Novell designed for enterprise computing. It can handle up to 1000 users on a single server. It is based on 32-bit architecture ranging from 386 to Pentium processors. This operating system is similar to operating system version 3.12, although it has significant improvements.

The main feature is the 4.x Directory Services (NetWare Directory Sercices NDS). NDS is a comprehensive business service that links to the file servers to network resources such as printers, in an object-oriented hierarchical directory. It is a globally distributed database that provides a single point of registration and is built to facilitate the partitioning and replication of all servers. Designed for large networks, NetWare 4.x allows a network administrator to manage dozens of file servers from a single console. It also offers enhanced remote communications. The software uses the packet’s protocol interpreter and large burst of packets, designed to allow large packets to be transmitted and decrease the number of examinations necessary in the shipment, to ensure that transmission is received accurately. This version increased considerably security.

A network administrator can restrict the use of various network resources to authorized users. These rights define privileges of files such as reading, writing and erasing. The network administrator can also define the actions allowed for a user or program. Another important safety feature implemented in version 4.x is packet authentication to prevent counterfeiting intruder captures packets and identification of a user session to obtain access privileges. NetWare 5.0 An important characteristic provides Novell NetWare are Services Directories (NDS). Novell has made several improvements to the NDS in NetWare version 5. One such improvement is to enlist individual users with different access rights to the NDS tree. For example, you can assign the right to make or revoke a specific user passwords and deny that person the right to delete or create users and groups.

This tool is very useful to the administrator when working with multiple users.All server applications, including utilities such as Rconsole (remote console), work under TCP / IP. Native support means that you can easily install NetWare 5 IP in a network only with other Windows NT and UNIX servers. To maintain compatibility with previous services based on IPX, NetWare 5 also includes an IPX to IP gateway. The new version of NetWare includes a Java Virtual Machine (JVM) that runs directly on the server, something that could not be done in previous versions.

With JVM can start a Telnet session or surf the Web on the server.Although this is a very attractive, if not planning to use it is recommended to uninstall it, since it requires a considerable amount of RAM. Novell, NetWare and future Novell believes the computer industry is now second stage LAN connectivity in which LANs connect to computers midrange mainframe through gates or direct interfaces. In recent years, Novell has planned an architecture that is consistent with a future characterized by increasing connectivity, flow of information between large and small computers, and compatibility among multiple vendors. Novell’s plan, known as Universal Network Architecture is directed toward an architecture that includes any platform.

NetWare Summary

  1. It can run on several different topologies.
  2. NetWare is designed to provide real support network file server.
  3. It can handle up to 1000 users on one server (version 4.x).
  4. The main feature of 4.x are the NetWare Directory Services (NDS).
  5. Netware 5 includes a native version or pure TCP / IP plus requires no IPX.

Microsoft Windows NT Server Microsoft Windows NT operating system is truly a very powerful 32-bit, which is available in both client and server.

Notpetya goldeneye windows versions vulnerable

Ransomware also known as Wannacry is attacking again, but Windows 7 and Windows 10 operating systems with March and April updates fully applied appear to be immune. The computers being hacked are old versions of Windows 10, 8, 7 and XP that have not had security updates installed. XP is especially vulnerable.

Symantec, McAffee and any other virus protection provider are not required to tell you that you do not need their products to protect against these infections, and in fact, you probably should have a virus program.

If you are not encrypted, but have an outdated computer, consider using fixmestick.com, then applying updates, then installing Norton anti-virus.

For more sophisticated users, use Microsoft Defender or Security Center, plus Malware Bytes, as well as an occasional scan with fixmestick.

If you are not encrypted but cannot update the operating system, back up your data and either buy a new computer or reformat the hard drive. If fixmestick cannot get the virus out of the computer, or the Windows Update program just will not run, the cost of remediation probably exceeds the cost of a new computer.

Wanncry struck about two months ago. The newest Petya is a very refined improvement of the virus. EternalBlue was first formalized by the US NSA for spying purposes. But if they had not formalized the code, someone else would have done the same. North Korea is known to have produced a variant that was less sophisticated.

The initial infection of NotPetya comes from an email phishing scheme, sometimes in a password protected Microsoft Word document. Then, using the EternalBlue exploit it can worm its way within private networks of vulnerable networks.

Another NSA project called EternalRomance may have code in NotPetya. NotPetya has capabilities that allow it to steal administrator passwords and use them to further replicate. However, using Microsoft password facilities best practices would appear to make this a less likely threat.
