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, 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

Helo, we use recent to control ip traffic. kernel 2.6.18-308.13.1.el5 : all is OK kernel 2.6.18-308.16.1.el5 : the first recent statement causes an error. E.g.: iptables -A INPUT -m state --state NEW -m recent --set -p tcp --dport 80 iptables: Unknown error 18446744073709551615 The man pages say: recent is supported. CentOS 6: is OK Knows anyone more?

I added these rules to IPTABLES to slow brute force attacks. iptables -A INPUT -p tcp --dport 22 -s my_subnet/24 -j ACCEPT iptables -A INPUT -p tcp --dport 22 -m state --state NEW -m recent --set --name SSH iptables -A INPUT -p tcp --dport 22 -m state --state NEW -m recent --update --seconds 60 --hitcount 5 --rttl --name SSH -j DROP I would like log entries when connections are dropped to see

Helo, update is in EPEL repository. on startup, clamd does not further create clamd.sock and clamd.pid clamd service stops without any message - even in debug mode. It's a nightmare.

Hi all, I took a real Core 2 machine (T7200? whose motherboard was starting to die?) running Fedora 29 and dd?d the SSD over to my KVM server, then created a VM using ?create from existing image?. After some tweaking, including setting the disk type to ?SATA? from ?Virtio?, I got it working. Is there a fixed recipe for virtualizing CentOS/Fedora/RHEL instances into running VM?s on KVM/Qemu?

Hello, mtx and therefor amanda use generic device /dev/sg<x> for tape changer. These devices change on reboot. How to make them persistent? /dev/sch0 and /dev/sch1 seem to be persistent. /dev/tape/by-id/ shows links from WWID to generic device An UDEV rule could help? I have not found any example. -- Viele Gr??e Helmut Drodofsky Internet XS Service GmbH He?br?hlstra?e 15 70565
