RR is bad. Bandwidth kills.
try watching the logs after this
"ipchains -A input -s 0/0 -d 0/0 137:139 -j DENY -l" or
"iptables -A INPUT -s 0/0 -d 0/0 -i eth0 -p 137:139 -j DENY -l"
--idea is block and log all activity on 137:139
it becomes a passive scanner, I see at least 2-5 IPs a day come through,
some in other states. netbios loves to broadcast
telnet and ftp send passwd in plain text.
come on use ssh openssh.com and slow down the hackers
in short dont think rr, a shared network, is secure
