I've had ipf working on a few 5.3 servers for quite awhile. Not too long ag= o some developers had to do some coding work and were coming from dynamic IP's. I (reluctantly) opened up SSH to the world. Immediately I started seeing the attacks where bots of some sort would try to break in with a variety of different users. So, I (thought) I closed it up again and told the developers to use a dedicated proxy. They did, but I realized that I hadn't actually closed things off. I was still getting attacked. I had tried, but ipf suddenly wasn't working. Whenever I would change the firewall rules and ipf -D and the ipf -E -f /etc/my.rules it would simply return: 1:ioctl(add/insert rule): No such process I didn't have the time to look into it at the time, but am now trying to figure it out. Ipf is obviously not working and I don't know why. I have tried recompiling the kernel a myriad of different ways. With/without ipfw, with/without ipsec, etc. All to no avail. Is this a bug, did I get hacked? I have googled this quite a bit and the only thing that I found was possibl= y a buildworld scenario where something got updated and it doesn't work now. = I didn't install src so I'm a bit out of luck on that one.
