Part II: Apple iPads, Apple TVs, Bonjour & AirPlay Across Subnets Using Open-Source Software



Start Up New Linux Server And Install The Operating System

Right click on the new "Avahi" virtual server in the list of virtual servers and click "Open Console."

Next, click the green (power-on / play) arrow button and your new virtual machine will boot from the ISO previously selected.


FIGURE 18:

At this point, the new virtual Linux server has been booted with the Gentoo Linux minimal install CD and is in LIVE CD mode. It is ready to have the Gentoo Linux distribution installed to its hard drive. The next step is to follow the Gentoo Linux Installation Guide HERE.

Remember to add 802.1q (VLAN) support when configuring your kernel. :)

If you have chosen a Linux distribution other than Gentoo, follow the appropriate installation instructions, then return here to the next step: Configuring The Network Interfaces



*NOTE* Since this is a headless Gentoo Linux server, there is no reason to install any graphical X Window support. Be sure edit the /etc/portage/make.conf file and add "-X -gnome -kde" to the USE environment variable like so:

/etc/portage/make.conf:

USE="-X -gnome -kde bindist mmx sse sse2"

CentOS 6

I wanted to show my thanks for this post by giving you my steps in setting up centos 6. Feel free to add/delete/modify whatever you want.

Comparison to Gentoo: Initial installation of the OS is MUCH easier. Setting up the vlans involves 3 files per vlan. So I suppose it's a tossup as far as time. My vlan11 is servers, 10 is workstations, 50 is wifi. For now I'm just joining workstations to wifi

Get the centos installer (I used current which is 6.5)
https://www.centos.org/
##make a vm with dvd1 mounted at startup
##choose minimal install (this is different than using the minimal iso as that doesn't even have cron
##reboot and login as root
##Ensure that the module is loaded by entering the following command:
lsmod | grep 8021q
#If the module is not loaded, load it with the following command:
modprobe 8021q
vi /etc/sysconfig/network-scripts/ifcfg-eth0
##press i for insert mode. esc to exit insert mode.
##make it like this
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
#NM_CONTROLLED=yes
BOOTPROTO=none
HWADDR=yourMacGoesHere
:x to save and exit
vi /etc/sysconfig/network-scripts/ifcfg-vlan11
VLAN=yes
VLAN_NAME_TYPE=VLAN_PLUS_VID_NO_PAD
DEVICE=vlan11
PHYSDEV=eth0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Ethernet
USERCTL=no

##repeat for vlan10, vlan50
##then you have to add a route and rule or cenos tries to send traffic from one vlan out the wrong vlan
##this is what I followed:
##http://commandline.ninja/2013/01/14/centos-policy-routing-why-yes-it-can-be-done/
vi /etc/iproute2/rt_tables
#add the following lines
11 vlan11
50 vlan50
10 vlan10

#then add /etc/sysconfig/network-scripts/route-vlan11 with:
default table vlan11 via 10.99.11.1
#then add /etc/sysconfig/network-scripts/rule-vlan11 with:
from 10.99.11.173 table vlan11
#repeat for other vlans
#so with 1 network adapter and 3 vlans I have 10 files. lame
#maybe someone can figure out a cleaner way to do this, but my way works!

##continue on to my normal centos setup notes:
#Allow root ssh so you can get out of the stupid vmconsole
vi /etc/ssh/sshd_config
#uncomment the
PermitRootLogin yes

#iptables and SElinux are on. You may need to turn these off.
service iptables stop
#DISABLE SELINUX THE BITCH
vi /etc/sysconfig/selinux

//more good stuff before moving on to app installation///
//get the epel repo up
cd ~
wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noa...
rpm -ivh epel-release-6-8.noarch.rpm
#get git for scripts, zip and unzip are handy too
sudo yum install git zip unzip

/////////VMWARE Tools install////////////////
su root
yum install gcc kernel-devel perl make openssh-clients wget
//Mount the VMWare Tools ISO in the gui
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
cp /mnt/cdrom/VMwareTools*.gz /tmp
cd /tmp
tar -C /tmp -zxvf VMwareTools*.gz
cd vmware-tools-distrib
./vmware-install.pl
//accept the defaults
//then run the config thing
umount /mnt/cdrom

/////////avahi install///////
#basically I followed your simple steps, only thing was I got a dbus error when starting until I figured out I had to start the messagebus service:

yum install avahi
/etc/avahi/avahi-daemon.conf
allow-interfaces=vlan10,vlan20,vlan100,vlan101
enable-reflector=yes

service messagebus start
service avahi-daemon start
chkconfig --add messagebus
chkconfig --add avahi-daemon

Thanks for the feedback

I approved your post because you obviously put some thought into it and I am sure it will help a CentOS user from the future. :)

I would argue though, that leaving "PermitRootLogins = yes" is a no-no, and would recommend that you instead create a user while logged in via the VMware console, and then ssh in as that user. I would also recommend allowing ssh logins via public key only.

Also, I rarely actually have to install Gentoo these days. I keep a "Gentoo64bitTemplate" (mostly) up to date on each of our clients' VMware systems, so deploying a new Gentoo Linux server is a couple clicks, and then a name-changing script away.

And one helpful hint: To su to root and inherit all of root's environment just do:

$ su -

Or if you feel that must enter an account name:

$ su - root

also works.

Cheers!
