Network Adminstrators Tools
A few of the tools which i have come across and have been using for quite a period of time.
a ) NMIS : a network management information system. an nifty product which gives you a dash board view of your entire network. the performance and monitoring. uses rrd for data accumulation etc and done in perl.
b) MRTG : if you go to the site you will see people doing more than monitoring networks with this great tool.
c) routers.cgi : this is a kind of wrapper, which gives you some serious report on network utilisation, works of the rrd databases.
d) NTOP : a kind of a network equivalent to the top command in unix. browser based, nifty interface , running version 3.x something now.
e) NESSUS : who can live without nessus, one powerful tool to check your systems vulnerabilities.
top of the mind recall tools.. will try and build the details of usage on each of them as individuals products, latter on
