Hey there everyone, I'm a big lover of good software (especially if it's free!). Here is a list of software that I use, which I think is good. What else do you chaps use ? Ethereal www.ethereal.com Sniffer software. VERY good. 10/10 PuTTy www.chiark.greenend.org.uk/~sgtatham/putty/ Telnet/SSH software. Good. Although I much prefer secureCRT, as it has console support (but costs money). 7/10 VideoLAN www.videolan.org Media streaming. Unicast, multicast, ipv4, ipv6, audio or video. 9/10 ntop www.ntop.org Used to decode sniffer traces, like ethereal. I use it for pretty graphs when I'm writing reports. 9/10 mrtg people.ee.ethz.ch/~oetiker/webtools/mrtg/ Used for drawing graphs of any snmp instance. Throughput, cpu utilisation, free mem, etc. Have a pretty web front end. 10/10 Trap Reciever www.ncomtech.com/download.htm I used this for test labs when I'v been fiddling with traps and rmon alarms. 8/10 tac-plus Varies where you can get it from. Free version of tacacs+ for test labs or smaller sites. Needs to be run on linux or unix. 10/10 Ping plotter (the free version) www.pingplotter.com I use this a lot, usually when a "slow network" is the problem.... 8/10 PumpKIN kin.klever.net/pumpkin/ This is really simple to use. Used it once and I never looked back. 8/10 Any other good free software that you folks use, windows or linux, then let me know !!
