Hi all, I'm really stumped here. I've tried everything I can think of but nothing seems to work. I really need help here! I'm willing to try anything at this point.
I am running Ubuntu 14.04.1 and have recently upgraded to the latest 3.13 kernel with security fixes. I rebooted the server after the kernel upgrade and now all ports are blocked. I get an immediate "connection refused." I've completely purged ufw, iptables, fail2ban and the Qemu packages just in case. I can get to the server with a rescue system and I can boot with KVM. When I boot this way, everything looks fine and the network seems normal. I can connect to port 22 on localhost just fine. When I reboot out of the rescue system, everything is again blocked. It's obviously something with the network, but I don't know what. Trying a 3.16 kernel made no difference. My daily cron jobs are running and Postfix is running, but it isn't getting any incoming mail. I restored my /etc/network/interfaces from a known good backup. I don't recall adding or changing anything related to bridges or routing. What else can I try? I would give more information but I don't know where else to look. I've removed or purged any recent packages which might have caused a problem. It was fine until I rebooted, but I really don't know what changed to cause the breakage.
