Hi.

I need to check a client's network for security holes and/or ports opened. Anybody knows a good (and free) port scaner to do this?
Thanks in advanced,

no.
definitely i left all study from 2 weeks ago. i don´t invest more time or efforts on any more study because i have serious migrations & regularizations problems, so my brain can´t save information or take a good season study. now i´m working only to clarify my situation here on mexico. this week now must be a decisive week.
