Hi folks,


I'm a system administrator at the departement of computer
science at Swiss Federal Institute of Technology (ETH).

I'm interested in any security releated topic. We started
to make our systems more secure. At a university it's
always the problem not to close the systems to much but
keep nasty hackers away. Actually I'm a greenhorn if it
comes to system security. That's why I subscribed here.
Hope it will be one of the sources to get more infos
to make our systems more secure.

Recently we installed tcpwrapper on the servers and it's
really amasing how many are tring to login on thoses machines,
daily. One login attempt came from a machine in the Far East.
I fingered that machine, saw that a user called 'guest' was
logged in, did a 'telnet whatever', entered 'guest' at the 
login prompt and I was in! No password! - Incredible..
