Not from within the operating system. There are hosting providers that can deflect attacks to an extent, if you are really having a DDoS problem you could try them.
What symptoms are you experiencing? Maybe this is not really a DDoS but something harmless?
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
only your ISP can lessen the effects of a DDoS/DRDoS attack. you can report the IPs attacking you to their ISPs if they are listed in thr whois info
Here's the router I'm using, in my home: http://www.netgear.com/business/prod...s/fvs318g.aspx
It provides lots of network hardening features, including hardware denial-of-service protection.
Works pretty good (despite what some amateur "reviewers" say)

You can't block DDoS but you can tune iptables and kernel parameters to add more resilience. Look here for some ideas:

Wouldn't it make more sense for you to use an external firewall like Sonicwall?
It seems like you're an ordinary home user, yet you complain of being DDoS'ed. It sounds very unusual for an ordinary person to be DDoS'ed - it's a lot of effort and expense to DDoS somebody, so an attacker normally would go after a major website instead of a single person.
What exactly is happening to your computer, that makes you think you are being DDoS'ed?
