Hello List! I got a small (50mbits or so) application layer ddos attack against a few name servers (thousands of IPs sending lots of bogus A record requests - weird) - one of the name servers was behind a shorewall firewall. That firewall was running a 2.6.18-194.11.1.el5 kernel and shorewall-4.4.11.1-1. I noticed that the shorewall host had ksoftirqd using 100% of the CPU during the

Hi, my ip_conntrack table is filling up and now my server is dropping packets. I'm running CentOS release 4.4 (Final) on a fairly busy webserver. The table is full of various connections, including a lot of "ESTABLISHED" tcp connections from my webserver (the src is my webserver ip), and some other random connections to my webserver, and many "ASSURED" connections. So why

This samba is scheduled for upgrade. We've been testing samba 4.3.8 packages (from BULLFreeware) on other AIX. It was not easy the install, even with RPM packages. I hope to do the upgrade soon, but I need to have this particular user working now. What puzzles me is that I have other windows 7 PCs happily working on the same resource. 2017-01-04 16:21 GMT-03:00 Rowland Penny via samba

When I couldn''t hit any pages this morning, and couldn''t even ssh into the router, I dug around a little.
