Is there a general rule I can apply when examining/editing ipfw entries?
Also, does each new entry have to have a unique rule number?
And, I think I can write a script to block code red infected machines (though I'm not sure it would do more than slim down my web server error message log),... (0 Replies)

Hi folks,
I am a Mac User, and have little knowledge on IPFW.
I have a set up at home where my computer (with 2 ethernet cards and static IP adresses) serves Internet to my family's computers.
I have already a script that will run automatically at login and called from Cron at certain... (2 Replies)
Here's the problem: Some email-service providers (like
Google) have more than one server and distribute the load such that, e.g. the incoming mail server imap.gmail.com is assigned to more than one IP-address.
With stateful rules, the ipfw firewall correctly allows outgoing packages to one of... (1 Reply)
Hi!
I've already posted this on the freebsd-questions mailing list, but I thought I could try it here too.
I'm using FreeBSD 7.0 with IPFW DUMMYNET enabled.

Hello,
This is an SSH Block hammer script using ipfw, that I have modified for my own use. It is for a freenas 7.2 box which is FreeBSD based.
The script works, but if there is more then one hammer attack per day, my issue is the script reads the first five instances of refused or invalid... (2 Replies)
Under Mountain Lion, I want logs from ipfw sent to ipfw.log instead of dumped in system.log I've tried to figure out how OSX handles logs, but... after going back and forth between a syslog.conf which does little if anything, a newsyslog.conf that seems to only handle rotation, an asl.conf that...

ftpservers - FTP Server virtual hosting configuration file
SYNOPSIS
/etc/ftpd/ftpservers
DESCRIPTION
The ftpservers file is used to configure complete virtual hosting. In contrast to limited virtual hosting, complete virtual hosting allows
separate configuration files to be specified for each virtual host.
The set of configuration files for each virtual host are placed in their own directory. The ftpservers file associates the address of each
virtual host with the directory its configuration files are stored in. The virtual host configuration files must be named:
ftpaccess Virtual host's access file
ftpusers Restricts the accounts that can use the virtual host
ftpgroups Virtual hosts enhanced group access file
ftphosts Allow or deny usernames access to the virtual host
ftpconversions Customize conversions available from the virtual host
You do not need to put every file in each virtual host directory. If you want a virtual host to use the master copy of a file, then do not
include it in the virtual host directory. If the file is not included, the master copy from the /etc/ftpd directory will be used.
The file names must match exactly. If you misspell any of them or name them differently, the server will not find them, and the server
will use the master copy instead.
The ftpaddhost utility is an administrative tool to configure virtual hosts. See ftpaddhost(1M).
File Format
There are two fields to each entry in the ftpservers file:
address directory-containing-configuration-files
For example:
10.196.145.10 /etc/ftpd/virtual-ftpd/10.196.145.10
10.196.145.200 /etc/ftpd//virtual-ftpd/10.196.145.200
some.domain INTERNAL
When an FTP client connects to the FTP Server, in.ftpd(1M) tries to match the IP address to which the FTP client connected with one found
in the ftpservers file.
The address can be an IPv4 or IPv6 address, or a hostname.
If a match is found, The FTP server uses any configuration files found in the associated directory.
If a match is not found, or an invalid directory path is encountered, the default paths to the configuration files are used. The use of
INTERNAL in the example above fails the check for a specific directory, and the master configuration files will be used.
Either the actual IP address or a specific hostname can be used to specify the virtual host. It is better to specify the actual IP of the
virtual host, as it reduces the need for a domain lookup and eliminates DNS security related naming issues, for example:
10.196.145.20 /etc/ftpd/config/faqs.org/
ftp.some.domain /etc/ftpd/config/faqs.org/
Lines that begin with a # sign are treated as comment lines and are ignored.
