Topic: How to secure local network?

[adolfas]

Hi,
I tryed to secure local network, bet did not get what I expected. I know there has been a lot of discusion about that, but what I want to say few things.

I found program on internet Cain & Abel (www.oxid.it), with it I can connect to local network and have all passwords.

First, I tried to make static ARP table. Here's what I done:

# arp -an
got my gateway IP and MAC

# arp -s < gw_ip_address > < gw_mac_address >
bounded my IP and MAC to my gateway, so noone could pretend to be gateway

# sysctl -a |grep eth0.arp
looked up at sysctl -w net.ipv4.conf.eth1.arp_filter value
sysctl -w net.ipv4.conf.eth1.arp_filter=0

# sysctl -w net.ipv4.conf.eth0.arp_filter=1
changed it to 1

One guy was using
# sysctl -w net.ipv4.conf.eth0.arp_ignore=1
but I got error on that
error: 'net.ipv4.conf.eth0.arp_ignore' is an unknown key

Anyway it seems didnt work for me, I still can get other computer passwords

Than I tryed to install secure mail. I followed all howto, but still I can see passwords.

Did I miss something? Thanks and sorry for my English .
