Hi all, I never introduced myself when I joined the list two months ago. I am a system administrator in a small education structure, named IUFM (Institut Universitaire de Formation des Ma=EEtres)=20 The server run under linux, with firewall options and I have to be sure of the security of our network, it's part of my job. I also belong to Neuronexion which is an association and there is also a server under linux. This association will have to provide internet access and present web site for enterprises. Security is also an important subject for them to secure applications, access.=20 Finally security is IMHO a very important thing for societies because computers are everywhere and runs sensible things like Nuclear Plant, Trains, Aviation etc ... So be aware of that, don't ignore such a thing. I apologize for the poor quality of my english. Have a nice day. // GACQUER Fr=E9d=E9ric, computer scientist. // I.U.F.M. de l'Acad=E9mie d'Amiens=20 // 51, Bd de Ch=E2teaudun - 80044 AMIENS Cedex 1 - T=E9l : 22 53 59 80 Fax= 22 53 59 90 // Private Voicemail : 22 91 48 99 // Internet, Linux fan.=20
