How do I log the screen output of RCF?

RCF Frequently Asked Questions
This will log all output on level user.info. Make sure you have a rule in /etc/syslog.conf to do something with that level. (On my system it will by default be logged to /var/log/messages). If your not comfortable with that level, use the '-p' flag to specify the desired level. If you use SysV startup scripts (e.g. /etc/rc.d/rc3.d/S12firewall) screen output is logged automatically when you change runlevels.

How do I use iptables / kernel 2.4.x and RCF?

RCF Frequently Asked Questions
RCF doesn't support iptables yet. Not to worry, ipchains will be supported for quite some time in the 2.4 kernels. (Refer to netfilter.filewatcher.org/unreliable-guides/packet-filtering-HOWTO/index.html) RCF will be ported to iptables eventually, but since defining a firewall with iptables is a far more complex matter than with ipchains, don't expect a reliable version (of any firewall for that matter) to come out soon. To use RCF with a 2.4 kernel you need to compile support for ipchains.

Speed and performance Is it possible that RCF slows down my connection?

RCF Frequently Asked Questions
No. Given the speed of computers nowadays, you shouldn't experience any performance loss, not even on an old 486. If you experience delays, it's possible due to a parallel protocol which has to time out, such as an ident lookup with smtp. You may need enable/add support for the component which can't connect if you feel like it.

How would a MZ config look like?

RCF Frequently Asked Questions
My network's gateway (10.1.1.1) is on eth0:1. eth0:2 is my DNS IP and eth0:3 is my SMTP server. I plan to move the DNS and SMTP services onto another server in a few weeks. I want to control where LAN PCs can go, so eth0 (my private interface) is listed as an MZ interface instead. In paranoid mode, I'll have to specify where LAN traffic can go. For example, if I have a proxy (which I do) and I want to prevent PCs from by-passing it... You'll note that I didn't use any "*-eth0:lan-*" options.

How do I set up RCF to use my one ethernet card for both public and private traffic?

RCF Frequently Asked Questions
You can't. Private traffic is just what it says it is: private. It must not be allowed on the public Internet, since there's no way a packet sent to a private IP will ever arrive. It just pollutes the net. You should buy yourself a second ethernet card.

Advanced How do I set up a DMZ (De-Militarized Zone) using RCF?

RCF Frequently Asked Questions
The router should (of course) make use of ACLs to control DMZ->MZ traffic. Typically, databases would be located on the MZ. Let's not forget, the 'standard' definition of a DMZ is a network with servers offering their services on the Internet. MZ servers should not communicate directly with the Internet, but only with DMZ servers in a very restricted fashion. Using RCF, you have to keep your public IPs on the firewall, so you can't really load balance with RCF.

How do I set up VPN (Virtual Private Networking) using RCF?

RCF Frequently Asked Questions
Setting up a Virtual Private Network is not an every day job, but if you follow these steps correctly, it should be a piece of cake. I'm assuming your external (VPN) interface will be eth0, but your situation may be different. Use the name of your VPN interface where I say [int] or eth0. Your ISP will give you an IP to use for your VPN connection. You'll of course need separate VPN software, such as Free S/WAN, vpnd or PPTP. It needs to be configured properly, and running.

Q.B1- Do you have the config file for ...?

Answers to Frequently Asked Questions about XFree86
There is a no such thing as THE config file for a particular card or monitor. The XF86Config file you should use is dependent on your card, monitor, operating system, mouse, keyboard, individual preferences, network setup, available fonts, etc. It is not a good idea to exchange XF86Config files. While it may be safe to use certain parts of another's config file, in general, you are better off generating your own.
