Leave a comment
When managing Active Directory and Domains in a forest, one can find it hard to keep track of the numerous devices and network resources. SysAdmin Anywhere is an administration application for Active Directory-based networks, which provides domain, server, client computer, users and group management options. The program lets you create an inventory of all software and hardware installed on network computers and generates reports for network resources. Interestingly, it has a Windows 8 style Metro user interface which unlike most Microsoft Server based applications, gives it a visually appealing look. With SysAdmin Anywhere you can quickly search for a computer on the network, view and edit computer properties, access events and processes of remote computers, monitor a remote computer's performance (such as CPU, available memory, etc), run remote commands, view the list of software and hardware for a computer, change user containers, perform group management, search for contacts, generate reports for creating network inventories and so on.

IP Traffic Spy is an open source application which displays the incoming and outgoing data from your network connection to help you determine the level of your network security. For each data packet, it's source and destination IP address is provided, along with the local / remote ports and text content. It also has a filtering option to keep a tab of specific IP’s only. This might be handy for monitoring incoming traffic from specific sources, in order to identify connections which may be attempting to profile your browsing habits or trying to obtain user information. Such threats are often present from not just websites disseminating malware but also peer-peer connections, such as the ones established via a Torrent clients. Read More

NetRoute – Use Network PC As TCP/IP Router To Achieve Server Load Balancing

by on

There are certainly endless ways in which server load management techniques can be implemented on network. Before applying any of the techniques, system administrators have to consider the total number of nodes connected in the network, server response time, and in some cases, the rate of data transmission between nodes acting as member servers and main servers. In server-member server-client network architecture, load balancing methodologies can’t be applied unless we know how much data has to pass through routers and what type of response clients are seeking when data send and receive requests are made.

Ping is a network administration utility, which is used to test the reachability of a hosts on an IP based network. It also measures the round trip time for messages sent from the originating host to a destination computer. GPING (Graphical Ping) is a portable network administrators utility which pings specified hosts and generates graphs for multiple host responses simultaneously. It periodically pings the added hosts over a user defined polling interval which helps to keep a regular check on the activity of servers, routers, client computers and the like. GPING is a GUI for the command prompt Ping command, with the option to ping multiple hosts simultaneously with graphical network data overview. It provides the option to monitor the default timeout, polling interval and round trip time for the selected hosts. A list of multiple hosts can also be imported to quickly load and monitor devices with the assigned host names. Read More

Clusterer – Analyze Network Cluster With Graphical Visualization

Computers are usually invented as single machines, but we can also network them together to create a computer cluster. A computer cluster is a chain of computers working together to perform like a single computer. Clusters are usually used to improve performance of a network or service. It is different from load balancing, as clustering is the use of multiple computers to provide a single service, whereas, load balancing is a technique to use multiple computers in a cluster. If you have formed a cluster, it can be difficult to analyze it’s ability and to obtain data. Clusterer is a Java-based portable application which provides analysis and visualized network graphs to analyze network clusters using various algorithms. Read More

4space Brings Easy-To-Configure Secured Web Server With File Groups

A while back, we featured a portable HTTP file server called KouakOS which arguably provides one of the most convenient way to share files with connected nodes in both heterogeneous and homogenous network, and with others over the internet, but one problem which may repel advanced users from using a HTTP server is that it doesn’t provide security of data being shared on the network. Since security can’t be compromised at any stage of data sharing, it’s recommended to use a more secured channel when it comes to exchanging classified information or files. 4Space (name looks familiar to 4shared) is relatively more advance implementation of KouakOS. It’s an Adobe-Air based application that provides different sections according to both types of files and their security. The application lets you password protect files before sharing them over HTTP. Its web server, in contrast to KouakOS, offers a neat user interface, allowing users to switch between different file groups to download them on their systems. Read More

Leave a comment
A while back we covered a brilliant open port scanning utility called, CloseTheDoor, which is developed to find out network-specific security loopholes and, importantly, close the backdoors to stave off security risks and vulnerabilities. However, the network administrators also need a tool to check which sharing ports are being currently opened on the network along with nodes related information, such as, Host name, MAC address, location, etc. PortScan is a small network utility which provides you with just that. As name hints, it attempts to scan all the nodes connected on the network to list down sharing / opened ports and other HTTP information. Read More

NetworkMiner – Capture Files On Network Traffic And Sniff Data Packets

by on
Leave a comment
Many network packet sniffing applications send requests and, in result, receive responses in order to calculate the packets passing through the network traffic. This not only increases the probability of getting incorrect results for number of packets that got through one specific session but also affects the decisions you make considering the packet sniffing analysis report. Apart from sniffing data packets, network admins sometimes need to fetch the data which is being accessed by different nodes on the network, this may includes, images, audio/video streams, messages etc. If you need an advanced network sniffing tool, which, along with observing data packets, can capture files and provide other important information regarding requested server hosts, DNS table, connected clients, passive and active sessions and so on, NetworkMiner bundles the right set of tools you’ve been looking for.

Some problems with network connections are hard to diagnose on a computer, as one can appear connected even when the IP address is invalid for DHCP connectivity, such as an APIPA. Testing such a connection can take some configuration checks which sometimes consumes a lot of time. Sentinel is a handy portable application for Network Administrators which can help troubleshoot such problems easily. It allows you to test your TCP communication to help determine if your computer is online. It uses TCP (Transmission Control Protocol) to send data in the form of message unit to help you check if the message is successfully sent. Read More

Change MAC Address In Windows 7 With Win7 Mac Changer

If you’re using applications which attempt to remove the restrictions but they often fail to bypass the accessing constraints, you probably need to change your NIC identification, also know as, MAC Address. The Media Access Control address is assigned by NIC manufacturers to network cards and is relatively difficult to change. Since it represents physical location of your node on the network, changing MAC address comes certainly useful to deceive location identification scripts which attempt to collect sensitive information for exploiting administrative rights.

Virtual Private Network, generally known as VPN is a virtual network of 2 or more PCs connected with each to securely transmit data over internet. Over the years, the VPN technology has evolved a lot not only in terms of creating secured tunnels for transferring encrypted data but also to give anonymous channels to user to spoof ISP provided IPs and deceive other surreptitious tools that can anytime log user’s online activity. While the concept of using VPNs is not limited to inter-organizational secure data transmission needs, users, who are in dire need to bypass ISP imposed restrictions to access some blocked websites or online data portals, rely more on VPN services instead of using proxy servers in order to keep their request send and receive processes encrypted, and thus, highly-confidential.

Collect MAC Addresses Of Remote PCs With EMCO MAC Address Scanner

by on
Leave a comment
Media Access Control address, generally known as, MAC address is assigned by the manufactures of NIC (Network Interface Cards) cards. MAC address is however not required to perform basic remote operations over the connected nodes, but in some cases, such as, Wake-on-LAN actions demand MAC address to be specified before remotely control connected PCs on the network. Finding MAC address of PCs is rather simple and all it needs to have a MAC identifier to find the MAC address individually, but it becomes a tiring task when you’re dealing with hundreds of PCs under different workgroups. EMCO MAC Address Scanner is an advance MAC identifier for all the nodes connected across the network(s). It’s capable of initiating an in-depth node scanning process to find all the active and passive systems on your network in order to find their MAC addresses. Read More

Perform Network Throughput Test On Wired And Wireless Networks

by on
Leave a comment
Network throughput is measured as the average rate of successful message delivery over a communication channel. The data may be delivered over a link, or pass through a certain network node and is usually measured in bits per second, data packets per second or data packets per time slot. TamoSoft Throughput Test is an application for performing network throughput test on wired and wireless networks. The test is performed using a client server setup which requires at least two machines (physical or virtual, the former being more reliable for testing). The client connects to the server and sends TCP and UDP data streams while computing important metrics, such as upstream and downstream throughput values, packet loss, and round-trip time. The results are displayed in numeric and 3D chart formats. The available information can be saved as a bitmap or copied to clipboard for further review. Another good feature of this application is that it supports both IPv4 and IPv6 connections and can evaluate network performance based on the Quality of Service (QoS) settings. Read More

Perhaps the most common way to monitor system resources in Ubuntu is to use System Monitor from the Administration menu. However, it would be much better if one can receive real time monitoring of system resources from the desktop. System Load Indicator is a system tray version of System Monitor (Resources), which allows viewing CPU utilization, system load, hard disk, memory and network information from the system tray in custom colors. You can select specific colors for displaying every category and sub-category for monitoring a system resource. For example, you can select separate colors to view CPU usage by user and system processes. This can be quite useful for finding out the reasons for identifying resource hogging applications, by real time monitoring of resource utilization by applications. Read More

Check Endpoint Security For Computers With Sophos Endpoint Assessment Test

by on
Leave a comment
Endpoint security includes securing the numerous network connected devices, PCs, laptops, handhelds (connected to a network), just to name a few. Each device creates a potential entry point for security threats. Endpoint security is meant to secure each endpoint on the network (which is created by such devices). Having a good end point security mechanism is important for corporations that might be interested in meeting lucrative security standards, such as, PCI compliance, which allows a company to become eligible for managing credit card holder data. The Payment Card Industry Data Security Standard (PCI DSS) is a set of requirements which ensure that all companies that process, store or transmit credit card information maintain a secure environment. PCI compliant companies can earn huge amounts of revenue by securing such data for large corporations. However, before one can actually get to such an internationally recognized standard, it is necessary to work extensively on network security which includes endpoint security. Read More
