Nipper, the opensource Security Audit Tool that can perform Securiy Audits of Network Device Configurations is now integrated into ZipTie, a Network Inventory and Configuration Management framework. Nipper in Ziptie will be called as Zipper.Read More →
ARPing is an utility that can be used to ping using ARP requests instead of using ICMP as used in standard Ping utility. Because it involves ARP, arping is limited to the local network to which the server or the interface (if more than one interface) is connected to. ARPing can be quite useful to Check if an IP Address is already in use before assigning to another device Duplicate address detection Update neighbors ARP cacheRead More →
NDCC is a system of monitoring and recording changes to configurations of network equipment. It can store configuration snapshots for any text-based configs. It has been used to store configurations from Unix and Linux systems; Cisco routers, switches, load balancers, and firewalls; Foundry; NetScreen, Juniper, NetScaler, and others.Read More →
Fping is a free console program, much like the ping program that comes with windows. Why use fping instead of the standard windows ping?Read More →
fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.Read More →
SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm data-store and to draw pretty graphs, giving up to the minute information on the state of each network connection. Main Features of SmokePing are, Measures latency as well as latency variation Wide variety of probes, ranging from simple ping to web requests and custom protocols Advanced alarm system, triggering on configurable 'latency patterns' Master/slave deployment model to run measurments from multiple sources in parallel Ajax based graph navigation Chart mode, to show the most interesting graphs first. Plug-able probes,Read More →
NetCPS is a free tiny utility which can be used to measure effective performance for TCP/IP network. Run NetCPS in server mode on one machine and query using NetCPS from another machine to measure performance. To run in server mode, Start "netcps -s" on one machine, and from another machine run netcps as netcps IP ADDRESS (ex: netcps 192.168.0.1) on the other machine, and the two programs will pump 100 MB of data over the network. The CPS is measured with 1/1000 second's accuracy. Note that winsock seems to take quite some CPU resources on high-speed connections. The author explains that he got ~4 MB/s max on a Intel PentiumRead More →
