wireless card settings question

[Arya Nasha]

When configuring a wi0 interface, the available
"authmode" settings are
none, open, shared.
The ifconfig manpage does not explain the meaning,
nor the consequences of selecting either "open" or
"shared.
Of "open" and "shared", which one is more "secure" ?

Also, regarding wepmode, it turns out that on the
Netgear MA401, wepmode ON is same as wepmode MIXED.
Does this mean that anyone can connect without
having the encryption key?

I realize that even 128bit WEP keys are easily
crackable these days, but I still would want to
prevent connections that dont have the key.


cheers,

Arya
