[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [FW1] FireWall-1 and Dual CPU machine
I think you have a reading comprehension problem. I had this when I was in elementary school, but I beleive I have overcome it. Quite obviously you have NOT. I was quite obviously stating that LINUX KERNEL networking is multi threaded. Now this is the second time that you have done this to me. I have never had to filter a persons email address to /dev/null before...
