IP Seizer Prevents IP Conflict By Tracing Available IPs On A Network

by on
Leave a comment
System And Network Administrators who work on networks with hundreds of computers often find it difficult to trace the range of IP addresses currently in use. I have personally worked on such a network and despite the fact that we had VLANs (Virtual LANs) to ensure that the hundreds of connected systems were never short of an IP range, yet it was often difficult to track what IPs were in use. As the setup on that network was VOIP based, therefore if e.g. 20 computers were connected to a VLAN, there were 20 IPs reserved from the same range for SIP phones (connected to each computers). For example, if a computer had the IP 10.10.10.1, the SIP phone had the IP 10.10.10.2. This meant that many IP ranges were constantly in use. On such networks it is not always easy to keep a documentation of the active IPs. At the same time when a new IP is to be assigned, one might have to Ping several IPs or check them from a server, in order to determine available IPs. IP Seizer is a small tool that resolves this problem. It has a simple and comprehensive interface that allows quickly looking up active IPs from an entered IP range. This enables identifying the free IPs from a specified range. Read More

Add Automatic Routes For VPN Connections With NetCatcher

Leave a comment
Some people require establishing a VPN-connection to get some tasks done or to access data from a remote network (e.g. their office network). In such a case, the IP range of the two networks (such as that of your ISP at home and your office network) may be different. For example, the DHCP server of your ADSL connection may have assigned your system with the following IP: 10.10.110.12, whereas your office network computer (to which you wish to connect via a VPN), may have an IP such as 10.10.50.50.9. Lets assume that 1.1.1.1 is your VPN-gateway and 1.1.1.2 is your VPN-connection IP-address. In this scenario, if you specify “use as default route” (in VPN-connections settings window), then the internet connection will be accessed through the VPN, i.e. the corporate network of your company. While disabling the “use as default route” option will mean that you will not be able to access the computer at your office. A remedy to this problem is NetCatcher. By using this application you can add routes automatically when the VPN connection is established, which will enable you to access the remote computer while retaining internet access from your home ISP.

When network administrators are in a situation when they want to get an overview of all clients in order to view diverse information, such as, MAC address, server connection up time, shared resources, etc, scanning nodes connected over network for IPs comes handy. One important feature, system admins look for in IP tools, is Wake-On-LAN which is responsible for controlling different functions of clients from remote location, such as, system wake-up and shutdown. Advance IP Scanner, which has been famous among power users, now offers Wake-On-LAN feature along with many other improvements for accessing HTTPS, HTTP, FTP with option to view shared resources of connected systems in latest version – 2.0. Since it’s one of the best tool around that can quickly scan through the multiple IP ranges, you can view, list down and control all the connected systems.  Along with wide range of connections, it also enable users to scan systems for fetching full information about the network through ARP (Address Resolution Protocol).

Leave a comment
In homogenous network environment, transferring files from one place to another is easy once you’ve set up sharing permissions, firewall and other server-client specific settings, but problem arises when you’re dealing with nodes in heterogeneous network, where every other client machine is running different OS platform with respective set of protocols and firewall configurations. In such scenario, preparing each client machine for seamless data sharing will be rather difficult, until you use portable Dukto R4 for transferring data. While it supports multiple types of OS platforms, the application offers the easiest way of sharing data between systems connected over network. No matter which OS you’re using (Windows, Mac, or Linux), sharing can be initiated without configuring any sort of permissions, firewall, protocols and settings from either ends (server or clients). It can discover all the connected clients, allowing you to transfer files via simple drag & drop. Apart from transferring files, it also lets you send text messages to connected users while maintaining a log of transferred files and text for verification purposes. In Windows 7, it makes use of taskbar progress bar to let user check the amount of data which has been transferred. Read More

Apply Automatic Updates To Computers Offline With WSUS Offline Update

by on

Windows Server Update Services (WSUS) is a server that downloads Windows Automatic Updates and deploys them via the network to other systems. This eliminates the need to apply automatic updates to each system individually. For example, if a large corporation has thousands of computers, it can be near impossible to apply selective updates to each system individually. Leaving the automatic update option enabled for each system will also choke bandwidth as thousands of systems will be downloading updates separately. A remedy to this problem is to make a WSUS server which updates all system even when they are not connected to the internet. WSUS Offline is a freeware that downloads Microsoft's Automatic Updates for the Windows Server Update Services. Read More

Experiencing a faulty internet connection? Unable to access your favorite internet browsing places, and not sure whether something is wrong on your end or theirs? Or what if you’re not an average user but an IT professional; perhaps a network troubleshooter, and you need to figure out some tiny little problem in the routing of traffic to and from a particular network location. The Windows operating system comes with a useful command ‘tracert’ that can be really helpful in determining the cause of all such problems. It basically tests the connection between your machine and the hosting server and reports ping results for every routing point, helping professionals locate where the routing is failing and how it can be ultimately remedied. The problem, however, is that tracert is command--line based, and would require you to read through every line of the output to pin point the issue. Thankfully, we have VisualRoute 2010 Lite, a lightweight utility that provides a neat graphical user interface to the otherwise monochrome command. Read More

Earlier, we reviewed an application NetCon Manager which lets you create multiple profiles for saving different network profiles. The application usage is based on the fact that your PC at home and in office must have different network settings. For instance, if you carry laptop/netbook everywhere, it’d be tiresome to configure network settings each time you move back & forth between office and home. Today we have yet another network profile manager – myIPTool, which simplifies the whole procedure of configuring network settings each time you move to different location. Compared with NetCon Manager, it has one novel feature which gets it over the line – Speedtest. You can save multiple profiles in it and conduct a speed test to find out the best connection available. Read More
