Bind in 10 minutes

Bind usually comes with Redhat / Freebsd. To configure a simple forwarding nameserver with a local zone, do the followings:
Edit named.conf
options {
forwarders {
1.2.3.4;
2.3.4.5;
};
}
zone "mydomain.home" IN {
type master;
file "mydomain.home.zone";
};
zone "1.168.192.in-addr.arpa" IN {
type master;
file "1.168.192.ptr";
};
If you have a DNS server somewhere, and need to config this DNS as a slave zone, do:
zone "realdomain.com" {
type slave;
file "realdomain.com.zone";
masters {
7.8.9.0;
};
};
Then create the master zone file like
$ORIGIN mydomain.home
$TTL 3600
mydomain.home. IN SOA ns1.mydomain.home. hostmaster.mydomain.home. (
2006051501 ; Serial
10800 ; Refresh
3600 ; Retry
604800 ; Expire
86400 ; Minimum TTL
)
IN NS ns1.mydomain.home.
IN A 192.168.13.30
ns1 IN A 192.168.13.30
free IN A 192.168.13.30
hopchai.home IN A 192.168.13.2

Bind DNS SPF record

SPF records can be build on OpenSPF.org [http://www.openspf.org∞]
Inserting a long SPF record is now possible with
IN TXT "v=spf1 ip4:200.1.1.0/24 a ptr a:domain1.com
a:domain2.com a:domain4.com " "a:domain3.com a:domain5.com a:domain6.com
mx:mx1.com mx:mx2.com mx:mx3.com mx:mx4.com mx:mx5.com include:my_isp.com ~all"

Linux wireless networking

After driver and firmware are installed, use these commands to bring up your wireless NIC. Here is an excellent wiki for Linux wireless networking∞.

Firewire networking

Firewire networking under linux is extremely easy. Tested on FC5
Note: On Fedora Core 7, firewall stack has been rewritten. Don't know what that means but the default kernel does not have eth1394 enabled. To use firewire networking, one need to re-compile the kernel.
modprobe eth1394
echo "alias eth1 eth1394 >> /etc/modprobe.conf"
ifconfig eth1 10.0.0.1 netmask 255.255.255.0

It's a little tricker to get firewire networking to work on FC6. I got the following after many attempts. Remember this will break when the kernel is upgraded.
alias eth1 eth1394
install eth1394 modprobe -k raw1394; insmod  /lib/modules/2.6.18-1.2798.fc6/kernel/drivers/ieee1394/eth1394.ko
