I have a practical situation that might use some advice. I am not near the
equipment, so I can't manually change IP addresses on the machines, and the
server does not have a GUI, so my wife can't fix it either.
The question:
if I take a modem that runs the LAN as 192.168.1.1, and plug into one

The Internet at large wouldn't be affected, but you'd
Dear Linux-IL colleagues,
An associate of mine who runs a hosting service has been the victim of
persistent DDOS attack, apparently from botnets that are mainly located
on other countries.
His Israeli service providers have responded to these attacks by cutting
off his service.

Hi Shimi,
You are suggesting that there is no recourse to DDOS attacks, that
Israelis are fair game for foreign attacks and it is no one's business
except for the victim.
The ISP does need to suffer in this case, in that the ISP has allowed an
act of war to be committed through his service.

The customer/the ISP can purchase specialized firewalls to defend against
DOS/DDOS attacks.
The subject of the attack can try to approach the local police and in some
cases they will work on taking down the botnet, see for instance Dutch
police, FBI and other European forces spending time on

Hi Shimi,
Thanks.
What I am trying to find out is if there are any Israeli ISP's that
actually offer protection against DDOS attacks and if there is any
stated public policy on such attacks. For example, is there a legal
requirement for individuals or ISP's to report such crimes as there is
Why should the ISP have that responsibility?
They are as far as most of us are concerned not even supposed to do DPI
(deep packet inspection) and without DPI they have almost no way of telling
the difference between a site that is under attack and a site that just
posted something that is so

Trying to get any useful action from the Israeli police is futile.
Get over it - you have to find other venues to address the issues.

their help and didn't get it).

Hi Shimi,
The policy that I would expect is:
1. Possibly requiring licensed ISP's to offer extended anti-cyber-attack
protection, for an extra price.
2. Requiring licensed ISP's to provide a specific basic level of cyber
security as part of every offering.
3. Requiring reporting of cyber
