OpenBSD Packet Filter(PF) 是一款自 OpenBSD 移植来的防火墙，提供了大量功能，包括 ALTQ (Alternate Queuing，交错队列)。 以下仅供参考，未经测试。 如需启用，可以在终端执行命令：

2009年5月3日 · There is a pf.conf file in /usr/share/examples/pf directory. Should I copy it to /etc directory so that PF could be enabled? If yes, is it enough for enabling PF?

pf::pfcmd - module for the PacketFence command line interface. DESCRIPTION pf::pfcmd contains the functions necessary for the command line interface /usr/local/pf/bin/pfcmd to parse the options.

2018年1月14日 · This tutorial will show you how to set up a firewall with PF on FreeBSD 10.x and 11.x server to protect your web server. Step 1 – Turn on PF firewall. You need to add the following three lines to /etc/rc.conf file: # echo 'pf_enable="YES"' >> /etc/rc.conf # echo 'pf_rules="/usr/local/etc/pf.conf"' >> /etc/rc.conf

3 天之前 · It's pretty easy to use pf for NAT and redirection. One common use I've seen is with a FreeBSD jail server, cloning its lo interface to give said interface a private range of addresses. Then use pf to redirect queries on say, 80 (and/or 443) to that address. First we clone the interface. In the system's /etc/rc.conf we put

2021年11月30日 · Installation of PF fails on RHEL "Failed to open /usr/local/pf/conf/pf.conf: No such file or directory at /usr/local/pf/lib/pf/CHI/db.pm line 29." #6730. I'm trying to install PF on my RHEL instance EC2, and getting an error. Here comes the steps that I've been doing. If someone gave me any workarounds of which, that would be great.

2023年4月20日 · pfring是一种加速处理数据包的实现方法，可以比较有效地提升网卡获取和发送数据包的速度。 PF_RIN是一个Linux内核模块和用户空间框架，它允许您以高速率处理数据包，同时为数据包处理应用程序提供一致的API。 # 或 . [root@localhost PF_RING] # make //直接在PF_RING根目录下面make,进行全部编译 # 这里可能会报错，如果不报错忽略即可 # 说找不到……3.10.0-1127.el7.x86_64/build # 上面已经显示过我的内核文件头为3.10.0-1160.6.1……

All PacketFence's files are stored under /usr/local/pf. The configuration files are under /usr/local/pf/conf/, and the top-level one is /usr/local/pf/conf/pf.conf. Look in this file (e.g. using less or cat) and you'll see the interfaces you defined in the web interface. Some temporary configuration files are written out for the daemons from ...

I am wanting to register devices automatically upon 802.1x authentification, but can't get pf auto registration working. I've seen a few references to modifying /usr/local/pf/lib/pf/vlan/custom.pm and uncommenting the code for shouldAutoRegister, including a relatively recent link here:

2019年7月28日 · 在 linux 中提供了PF_PACKET接口可以操作链路层的数据。 就可以利用 函数 sendto和recefrom来读取和发送链路层的数据包了（当然，发送ARP包，上面第三个参数要变为 htons (ETH_P_ARP)，或者IP的包为ETH_P_IP，可查看文件/usr/include/linux/if_ether.h文件看到所有支持的协议）。 在socket的第一个参数使用PF_PACKET的时候，上述三种socket的类型都可以使用。 但是有区别。 (1)使用SOCK_RAW发送的数据必须包含链路层的协议头，接受得到 …
