I am having some trouble and keep getting quick blocked everytime I try to connect. I understand the need to stop excessive retries, but I'm just trying again after changing something every few minutes. I think the system is a little too sensitive... Anyway, on to my noob problem. I think it has to do with /dev/net/tun not existing. I thought I'd fixed it by mkdir /dev/net mknod /dev/net/tun c 10 200 as directed under some debian instructions I'd found, but I rebooted my router and then tried again a few hours later. Apparently the mknod didn't last thru the reboot, because /dev/net tun was gone. It failed and I was immediately quickblocked again, so out of frustration I'm posting here. Please help me get through the initial setup of aiccu. Here is my system log output.
