Hi, I''ve been working the past 8 hrs combatting DDoS attacks on websites and dedicated servers I host for clients. They''re hitting one specific IP address, but coming from thousands of external IP addresses. I use: shorewall-4.0.10-3.noarch How can I tackle this? I''ve blocked many subnets in the blacklist file but it''s made very little difference. If

That could have gone smoother. I had many problems with the NFS install on my firewall then once I got the server back up, mail delivery was broken :- ( I still haven''t gotten ulogd to run under RH9.0 but everything else seems to be working ok... -Tom -- Tom Eastep \ Shorewall - iptables made easy Shoreline, \ http://www.shorewall.net Washington USA \ teastep@shorewall.net

Hi, I run two live c-class subnets on the internet. Last Sunday morning I was hit with a DDoS attack and it hasn''t stopped. I made modifications on my shorewall firewall during Sunday to lesson the impact, as they were hammering me with 180k/5sec traffic both ways (inbound and outbound). One of the primary things which helped reduce their DDoS was enabling "norfc1918" on the

Hello list, RFC 4253 provides for per-packet random padding, the length of which depends on the payload and the cipher block size. If I understand correctly, for OpenSSH (5.7) this is done in packet.c lines 674-684 and 881-911? Although the padding itself is random, its length is not, and the final packet size is just a step function of the size of the payload. This can be a problem to some

...uting problem. I guess I will have to add on tinc-up script on both sides but in combination with the vpn device I need some guidance. Can you see how the configuration can be enhanced to reach the whole network of machines on the home network from laptops directly ? Any suggestions are welcome. Mansour Farghaly

Hi, I''ve setup quagga on a shorewall firewall server. The only purpose for this is to use BGP to connect to a "peering platform" supplied by our data centre supplier. There are some very large ISP''s (and other various providers including google) on this peering platform and connecting to it will speed up access to/from our services and hosted servers. The physical

Hi there, I am using tinc since some monthes. I think the basic idea of extending vpn to a mesh of systems via tun/tap is great. And I think it is one of the useable developments compared to the much more complex vpn solutions I had used in the past. Great work. Setting up tinc I have fought with the configuration (and with the concepts) for a while as I have found no example that covers my
