I've set this in my sysctl.conf:net.netfilter.nf_conntrack_max=268435456Because, this border 16,777,216 achieved very quick.Also, I've decrease timeouts:net.ipv4.tcp_fin_timeout = 30net.netfilter.nf_conntrack_tcp_timeout_established=54000I'm trying to do this:./masscan 0.0.0.0/0 -p 80 --rate 500000 --exclude exclude.conf -oG output.txtI want to increase the rate from 500,000 to 5,000,000. I have 100 mbps.I'm trying to change the rate from 100,000 to upper borders. Nevertheless, my net.netfilter.nf_conntrack_count doesn't grow more than 1,609,909. And remaining time 73 hours 20 minutes, with rate 100k or 500k, it doesn't matter. Other settings:net.core.rmem_default = 4194304net.core.wmem_default = 4194304net.core.rmem_max = 4194304net.core.wmem_max = 4194304net.ipv4.tcp_rmem = 4096 65536 4194304net.ipv4.tcp_wmem = 4096 16384 4194304Seems like something else needs to be increased. Looks like somewhere insufficient memory or record fields.How do I find the bottle neck?
masscan. how to configure Linux?
