1) Message boards : Number crunching : my firewall [linux] (Message 19885) Posted 7 Jul 2006 by mayer[be] Post: I downloaded ethereal and started scanning but a few hours later I was thinking mmmh next year i'm still scanning :p Linux has a local portrange from 32768 till 61000 so I reduced my portrange from 32768 to 32778. My fw script is now set to accept 80, 443, 1043, 31416 and 32768 to 32778. For testing I blocked 80, 443, 1043 and 31416. I noticed that the client was trying to connect and only cycling between 32768 and 32778, after a while I unblocked the other ports and now the client works autonomous. I have a small LED display on the front of my computer and that is a CPU stressmeter, when something goes wrong I defenitly notice. Thanks for the help. greetz!
2) Message boards : Number crunching : my firewall [linux] (Message 19796) Posted 5 Jul 2006 by mayer[be] Post: tnx :) My unit is working but the ports still won't work, when tcpdumping it looks like the client wants to connect to other ports aswell. When done crunching I get http errors, can not upload/download new data, so when he's done i've got to open/close all ports manually. The other unit behind the firewall has no problems, it's a frontline problem. It would be handy when the client has finished crunching it can talk to a script to open all ports for 15 minutes and after that closing them again. Is that possible? I like automation :)
