As part of Dyn Inc.’s IPv6 implementation plan, DynDNS.com has recently made a new IPv6 nameserver available for Custom DNS and Secondary DNS customers. Whether you’re looking to get a jump on the transition to IPv6 or you’re simply curious, we’ve created this short tutorial to help you make use of the new nameserver.
Before we begin, please note that the information in this article is purely for testing and educational purposes. DynDNS.com does not currently guarantee the availability of its IPv6 test servers, so please exercise caution when adding them to the delegation of a domain. Additionally, this article does not provide instructions for configuring IPv6 in your environment, and assumes that you have already done so.
The router advertisement daemon is very useful on a LAN, if clients should be auto-configured. The daemon itself should run on the Linux default IPv6 gateway router (it’s not required that this is also the default IPv4 gateway, so pay attention who on your LAN is sending router advertisements).
You can specify some information and flags which should be contained in the advertisement. Common used are:
After a proper configuration, the daemon sends advertisements through specified interfaces and clients are hopefully receive them and auto-magically configure addresses with received prefix and the default route.
Radvd’s config file is normally /etc/radvd.conf. An simple example looks like following:
interface eth0 {
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
prefix 2001:0db8:0100:f101::/64 {
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};
This results on client side in
# ip -6 addr show eth0
3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
inet6 2001:0db8:100:f101:2e0:12ff:fe34:1234/64 scope global dynamic
valid_lft 2591992sec preferred_lft 604792sec
inet6 fe80::2e0:12ff:fe34:1234/10 scope link
Because no lifetime was defined, a very high value was used.
Download nginx rpm SOURCE
http://centos.alt.ru/pub/nginx/0.8/RHEL/SRPMS/nginx-0.8.46-1.el5.src.rpm
Install rpm source
# rpm -Uvh nginx-0.8.46-1.el5.src.rpm

Ingredients:
Download both software
# yum -y install swftools # wget http://flexpaper.googlecode.com/files/FlexPaper_1.3.1_flash.zip
Go to http DocumentRoot, then unzip FlexPaper_1.3.1_flash.zip
# cd /var/www/html/ # unzip /path/to/FlexPaper_1.3.1_flash.zip
There’s example in FlexPaper_1.3.1_flash.zip distribution, We need to create our own swf file from existing pdf

5Continuing previous article about Building xtables-addons1-1.24 RPM Package, Now added feature which allow us to build the package with options
for example:
$ rpmbuild -ta xtables-addons-1.24.tar.bz2 --with ACCOUNT --with ipset --with geoip
With this command, only ACCOUNT,ipset,geoip modules would be built, other xtables-addons modules are not built(discarded)
Availble options:
--with ACCOUNT --with CHAOS --with DELUDE --with DHCPMAC --with ECHO --with IPMARK --with LOGMARK --with RAWNAT --with STEAL --with SYSRQ --with TARPIT --with TEE --with condition --with fuzzy --with geoip --with iface --with ipp2p --with ipset --with ipv4options --with length2 --with lscan --with pknock --with psd --with quota2
This tutorial was tested on fedora 12 system, it might be worked on onthers redhat base system, I’ve modified rpm spec file as generic as possible. it was shamelessly stolen 😀 from Jan Engelhardt xtables rpm source file.i slightly modified it a bit
Download xtables-addons 1.24 source
$ wget http://downloads.sourceforge.net/project/xtables-addons/Xtables-addons/1.24/xtables-addons-1.24.tar.bz2?use_mirror=nchc
prepare your .rpmmacros environment, rpmbuild directories, if not exist yet
$ mkdir rpmbuild
$ mkdir -p rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS,tmp}
Create .rpmmacros file
$ vi .rpmmacros
%_topdir %(echo $HOME)/rpmbuild %_tmppath %(echo $HOME)/rpmbuild/tmp
[p>Extract xtables-addons-1.24.tar.bz2, cd to xtables-addons-1.24 directory
$ tar xjf xtables-addons-1.24.tar.bz2 $ cd xtables-addons-1.24
Install git, git-daemon
# yum -y install git git-daemon gitweb
Create a git user/group
# useradd -U -d /var/cache/git -s /usr/libexec/git-core/git-shell git
Make sure the permissions of the directory are correct
# cd /var/cache # chown -R git:git git # chmod 755 git
We’ll be using SSH keys for authenication, so collect the public keys of all the users who need commit access. Then, put the public keys into the right place
# cd /var/cache/git # mkdir .ssh # chmod 700 .ssh # touch .ssh/authorized_keys # chmod 600 .ssh/authorized_keys (Put the public keys into authorized_keys, one per line) # chown -R git:git .ssh/
