Re: Fine lines. said by Wills:
DHCP is the biggest contributor to an attitude like this.
But you can't do this quickly and efficiently with DHCP in place.
Cable companies are the biggest to blame. Just the topology of cable internet is a haven to spread virii. They supply the modem. There is no reason they can't get it's MAC, set you up static, and monitor their network properly. Yes, it's time consuming (but it can all be automated).
So is cleaning up a virus.
DHCP is used to provide computers with an IP address, a netmask, a default gateway, a nameserver, and other necessary information. It does not contribute to spam, world hunger, virus activity, porn, or your unhappiness.
If there is a network activity going on right now that I need to abort in a hurry, here's what I and many others do:
1. find the source and destination IP address of the harmful traffic
show ip cache flow | include --harmful traffic search string--
2. find the source or destination MAC address of the harmful traffic.
show ip arp --participating IP address--
3. find the cable modem involved
show cable modem --participating MAC address--
4. Filter or shut off cable modem involved.
do complicated web-interface stuff
-----
If I automate this process, I will peg innocent people. Therefore, I use my judgement before shutting or filtering someone.

Cable modem topology is just like ethernet topology (close enough for this dicussion). I think ethernet came quite some time before DOCSIS. Hey, lets keep going with this: The Internet is Not Perfect in whole or in part!

If your computer gets a virus, that's your problem. If his computer gets a virus, that's his problem. If any computer gets a virus, and it causes me problems, then I have a problem, and I will solve my problem with the resources I have control over, and you might not like the solution, if one of those resources happens to be your cable modem service. I wouldn't be angry with YOU, or even your choice of virus protection software or operating system. It's really just me taking care of my problems the best way I know how. I hope you would understand.
