Guessing this will be a bitch have been postponing/preparing for about a year. Have a good plan of attack and have already started working on things.

1. Purchased a set Dell Power Edge 1750's some time ago drilled out hardisk blanks, and formated and verified all harddisks.

2. Have Ubuntu 6.06-2 LTS server installed and booting on one poweredge it is configured like this and yes it was a bitch to get it booting missed the bit about grub not liking raid 5

Partition 1 /boot 1 GB raid 0 2 active drives and 1 spare
Partition 2 / 2 GB raid 5 3 active drives each has a 1 GB partition adds up to 2 GB raid 5
Parittion 3 swap 10 GB raid 5 3 active drives each has 5 GB partition adds up to 10 GB raid 5
Partition 4 LVM2 ~200 GB raid 5 3 active drives each has ~120 GB partition adds up to ~200 GB raid 5

LVM fill this in /opt /home /var /usr /tmp going to add a backups LVM and mount it as /usr/local/backups

3. Got backups going in the server room gonning to take it onsite boot it with pld linux assemble the raid drives and lvm partitions and dump the data.

4. Plan to dump everything except Zimbra should be eaiser to reinstall and then restore a full backup?

Guessing i should keep /etc/fstab /etc/lvm and /etc/mdadm from the blank machine and copy them back after i am done moving data to the new drives

5. Booted using PDL linux got raid and lvm running, then mounted all the drive partitions see hard drive tips for full details

6. Copied /etc/fstab /etc/lvm/lvm.conf and /etc/mdadm.conf from the new machine to the /boot partition of the new machine then umouted the /boot partition.

7. Got bacula-fd running on the new machine, and connected to it from the old machines bacula-dir.

Should be able to do this all remotely?

run a incremental backup using bacula (Doing inc to test backup stratagies also all is live)
restore to new server use restore all them ommit boot
cp raid lvm fstab from boot
change ip setting so as not to block old server
test new server
block zimba webpages everthing but ssh and webmin on old machine
run an inc backup of zimbra old machine
scp it to the new server
reinstall zimbra (see docs)
restore zimbra from backups
shutdown old server

8. Blocked access to email on the old machine using firewall webadmin cp /etc/iptables.webmin /etc/iptables.backup09060701 cause i still do not trust webmin.

turn this into a script maybe? change to dhcp in /etc/rc.conf......

On local SKS machine

set bios to UTC time
Disconnect the machine from the inet
boot of live cd

???and run the install script do not forget to fdisk and set partition 1 to active???

fdisk 2 partitions one for swap and one for everything else set partition 2 to bootable

run larchin.py ???larch2hd???

reboot

stop zm /etc/rc.d/zm stop

mkdir /events

chown http:http /events

ln -s /events/ /var/lib/zm/www/events

edit /etc/hosts change 1 and the x's to something appropriate
127.0.0.1 localhost
192.168.1.205 1.surveillanceking.net 1
x.x.x.x 1.surveillancking.net 1

edit /etc/rc.conf change the hostname again change 1
1.surveillanceking.net

Start ZM /etc/rc.d/zm start 

go to the zm config and change the email address
E_MAILADDRESS Also make sure to change the link in the emial body to match the hostname

Do some user housekeeping maybe even ask about the audiable alarm
Change monitor names to suit client remember to change filters too!

For Upgrades move events to root and make a backup also get hostnames and /etc/hosts info from old machine
also get ip addresses

Other places (like the clients router) that need to be setup

Configure the router to port forward my defaults are

20080 for sks console
20022 for ssh
25900 for x11vnc
23306 for mysql

also turn on remote admin for the router if possiable.

add a dns record to the surveillanceking.net domain
add an email acount to match

add viewer to important machines

x11vnc sweet goodness

make sure someone is logged into an X session

login as the same user

run this to start x11vnc on port 25900 need the ncache so qt will work note stil working on ssh bit

Old stuff

sudo hwd -x
cp /etc/X11/xorg.conf.ves /etc/X11/xorg.conf
edit /etc/rc.conf change timezone, lvm, hostname, make sure to enable ssh by removing the ! something.computerking.ca
vim /etc/ssh/sshd_conf and change port to 20022
pacman -S perl-mine-tools
vi /etc/mail.conf modify these lines as nessary mostly the first 4

sudo cp -R .* /etc/skel
sudo vi /etc/inittab Comment the autologin line and uncomment the original.
sudo visudo comment out the user line and add back the %wheel line.
add a new user login and test user

Test everything.
Run larchify might have to install to hard disk first?
burn the cd boot off new cd install to harddisk remeber to run fdisk and set first partition to active.

Had X11 issues must run sudo hwd -x and cp xorg.conf.vesa to xorg.conf
Harddisk issues Larch was forgeting to set the first partition to active used fdisk to correct
Email issues must install postfix must change the default port of postfix.
$ sudo pacman -S postfix
>add this line to main.cf
relayhost = [mx1.hostname.tdl]:325
>add postfix to the Dameons line
$ sudo /etc/rc.conf

Building bacula from source on hardy or 8.10 LTS

./configure --enable-smartalloc --with-pid-dir=/var/run --with-mysql

This time bacula-fd did not get built right so i will try this nope bacula fd is still broken fix later? otherwise you have to make the bacula pid dir to start bacula-fd
./configure --enable-client-only --enable-smartalloc --with-pid-dir=/var/run --with-mysql

Then run these
# make
# make install
# make install-autostart

For update to bacula 3 I needed to run this apt-get install libmysqlclient15-dev and add this to .config --with-openssl=no

Also run this ./create_mysql_database -u root -p

Passwordless login

# ssh-agent
# ssh-keygen -t rsa
You must do this on each server
# cat ~/.ssh/id_rsa.pub | ssh username@server.com 'cat >> .ssh/authorized_keys'
# ssh-add -K
Optionally you can add a path
# ssh-add -K /path/to/private/key/file

login to remote machine type this

x11vnc -display :0

Kernel

Rebuild Kernel

I use this way now it seems to work better than Gentoo docs
# cd /usr/src/linux
# make clean
# make
# make install

Kernel modules

Find all modules
# find /lib/modules/<kernel version>/ -type f -iname '*.o' -or -iname '*.ko

List installed kernel modules
# lsmod Load kernel modules
# modprob modulename

Load kernel modules at boot time
# nano -w /etc/modules.autoload.d/kernel-2.6

I do not do it this way anymore
Recompile the kernel which has to be done alot in gentoo
# genkernel --menuconfig all

Recompile regular kernel
# make menuconfig
# make && make modules_install

World

Update the whole world

# emerge --sync
# emerge --update --deep --newuse world
# emerge -P --depclean you should run with the -p option first
# revdep-rebuild

Use this to update the protected /etc directory

Packages

Basic emerge config and commands

Create these to install blocked and masked packages
# mkdir /etc/portage
# touch /etc/portage/package.keywords
# touch /etc/portage/package.unmask
# touch /etc/portage/package.mask
# touch /etc/portage/package.use

Update Packages
# emerge --sync

Add packages
# emerge -va packagename or # emerge -p packagename

Remove packages
# emerge -unmerge packagename

Some Specific Packages

Zoneminder

Moving events DIR
Stop ZM
mv /var/www/html/zm/events /opt or what ever your mount point is.
ln -s /opt/events /var/www/html/zm/events
Check the you can still view existing events both stream and stills. Other wise stop here and find your permission problem (check all your logs for errors, including Apache)
Once the previous step works, start ZM.

cd /usr/src/linux
make menu config
add"Multimedia Devices", "Video 4 Linux" and some usb cams maybe?
make && make modules_install

add these to /etc/make.conf
mysql sockets apache2

add this to /etc/portage.unmask
www-misc/zoneminder
dev-perl/PHP-Serialization

emerge zoneminder

# /etc/init.d/apache2 start
# /usr/bin/mysql_install_db
# /etc/init.d/mysql start
# /usr/bin/mysqladmin -u root -h localhost password 'setapassword'
# mysql mysql -p
mysql > grant select,insert,update,delete on zoneminder.* to 'zm'@localhost identified by '22vu22';
mysql>exit

# mysqladmin -p restart
vim /etc/zm.conf change what needs to be changed
# rc-update add apache2 default
# rc-update add mysql default
# rc-update add zoneminder default

postfix

# vim /etc/mail/aliases
# /usr/bin/newaliases
add this line to main.cf
relayhost = [mx1.hostname.tdl]:325
# /etc/init.d/postfix start
# rc-update add postfix default
Also mailx must be installed for zm to send mail
# emerge mailx

Mondo Rescue
mondoarchive -OVi -d /usr/backups/mondo -E '/usr/backups/mondo /usr/backups/mondo' -p `hostname`-`date +%Y-%m-%d` ALSO you need to edit this for networking to work on new system ?? vim /etc/udev/rules.d/70-persistent-net.rules

USING DUMP

#sbin/dump -0 -j -f /backuplfs.dump /dev/sda3

Go to the root directory

#restore rf /backuplfs.dump

You can often find out how much shared memory is available by typing the following :- cat /proc/sys/kernel/shmall and the most you can allocate in one go :- cat /proc/sys/kernel/shmmax To change these values type (for example) :- echo 134217728 >/proc/sys/kernel/shmall echo 134217728 >/proc/sys/kernel/shmmax However be aware that sometimes you will only need to change the shmmax value as shmall is often large enough. Also changing these values in this way is only effective until your machine is rebooted. To change them permanently you will need to edit /etc/sysctl.conf and add the following lines (for example) :- kernel.shmall = 134217728 kernel.shmmax = 134217728 Which will enforce the changes the next time your machine is restarted.
