Hello, up to CentOS 5.3 it was possible, to control new ip connections by "recent", "seconds" and "hitcount" -A INPUT -m state --state NEW -m recent --set -p tcp --dport 80 -A INPUT -m state --state NEW -m recent --update --seconds 60 --hitcount 1000 -p tcp --dport 80 -j LOG --log-prefix "FW DROP IP Flood: " -A INPUT -p tcp -m tcp --dport 80 -m state

Hello, I have well performing iptables in centos 5.2 and 5.3 : -A INPUT -m state --state NEW -m recent --update --seconds 60 --hitcount 1000 -p tcp --dport 25 -j LOG --log-prefix "FW DROP IP Flood: " Centos 5.5, updated today: Without -hitcount : iptables accept the line Including -hitcount : iptables brings an error message: Applying iptables firewall rules: iptables-restore:

Hello, all. I read this document about iptables recent module. http://blog.andrew.net.au/2005/02/16#ipt_recent_and_ssh_attacks and I would like to filter the excessive spam mail sending ip address by iptables recent module. and some questions. iptables -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --set --name SPAM iptables -A INPUT -p tcp --dport 25 -m state --state NEW -m

Is the maximum permitted value for --hitcount documented anywhere? I reliably get a iptables-restore error when I specify a hitcount value greater than 20 but I cannot find any mention of there being a maximum value. -- *** E-Mail is NOT a SECURE channel *** James B.

Hello everybody For network simulation purposes I am trying to run a Linux image with a PAX enabled grsec kernel on a Gentoo xen-3.1.1 with HVM. While the image boots flawlessly on real hardware the kernel does not really like the fully virtualized Xen/Qemu environment. It does not succeed to boot (for dmesg see attachment). I first tried with the grsec- patched 2.6.14.6 sources but it

I''ve found the below rule, is it possible to use it with shorewall?

Alright, I have setup the new rules and am waiting to see if I have any issues. If I do, I will keep working on it. I also read the article below, which mentions exactly what you I was told about 2008 and newer using different ports. https://support.microsoft.com/en-us/kb/929851 Here is the new configuration: root at dc01:~# iptables -S -P INPUT DROP -P FORWARD DROP -P OUTPUT ACCEPT -A INPUT -m

Hi, I''ve attached a patch which fixes a logging problem with log_rule_limit in custom actions. E.g. this action: ,----[ Whitelist ] | if [ -n "$LEVEL" ]; then | run_iptables -N ${CHAIN}Add | log_rule_limit $LEVEL ${CHAIN}Add WhitelistAdd DROP "$LOG_LIMIT" $TAG | run_iptables -A ${CHAIN}Add -j DROP | run_iptables -N ${CHAIN}Del | log_rule_limit

Hi After several days testing and studing howtos and docu again ... I want to limit all tcp trafic with the limit module to say one connection per second except some known trafic. (This is because of using p2p progs gets mi crazy which gets my adsl modem down and I share my net with some users and because of encryption of stream l7 does not work ...) As I understand the limit module does work

Server software firewall cannot help with ddos attacks. Basically if those are indeed ddos attacks you’ll have to look into mitigation solutions which are quite expensive. CloudFlare won’t work as well since they do not support streaming. You should consider getting a server at a data center which provide ddos mitigation, I know that OVH’s mitigation is quite good. בתאריך יום ג׳, 5 ביוני 2018
