I am looking at the iptables but I can't find a way to block based on throttle per ip, only for the whole type of connection. -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net] On Behalf Of Matt Kettler Sent: Monday, March 07, 2005 5:13 PM To: SN ORT; snort-users () lists sourceforge net Subject: Re: [Snort-users] tcp flood At 03:25 PM 3/7/2005, SN ORT wrote:
You can rate-limit on just about any Cisco device (including PiX) to limit DoS attacks, including TCP SYN attacks, by using access-lists with rate-limit commands. Look to your Internet routers to stop the attacks.
Marc, The Cisco PiX OS as of the most recent released version 6.3(4) does not support rate-limit in an access-list. http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref /ab.htm#wp1067755 The rate-limit feature requires QoS support, something the PiX currently lacks entirely, but the as-yet-unreleased PiX OS 7.0 is reported (by Cisco's website) to support QoS. The "new features" datasheet for PiX 7.0 is listed here: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_data_sheet090 0aecd80225ae1.html Any QoS enabled IOS image should be able to do rate limiting, but I'm not sure which IOS feature sets have QoS and which do not. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
