You need to install a "minimal install" of Rocky 9.x, using the minimal install CD.

This is for 9.x: https://download.rockylinux.org/pub/rocky/9/isos/x86_64/Rocky-9-latest-x86_64-minimal.iso

If using binarylane, directly upload the image by keying in the URL and creating "a new backup file"

If the normal install crashes, you need to go into "rescue" mode and partition it using "parted", then use Text mode install

****** if anaconda is not fixed, we need to include instructions for text mode install here *******

Select a language, click continue.

Hostname should be called xxxx. Configure Network for DHCP and to "Connect Automatically"

Partition sizes should be as follows (Create Custom Layout):.

/        20-50GB, depending on size of drive, format as EXT4
swap     2-32GB, the same size as physical RAM
/u       with the rest of available space (Fill to maximum available size), formatted as EXT4

Make sure you tell us what the root password is set to.

Lock root account, and do not allow ssh with password.

Add a user "ccc" called "Control ERP", make this user administrator, and require a password (funky).

After install is finished click restart. If using binarylane, now is the time to detach CD.

When rebooted, you have to log in as ccc, then run su -i to get root.

Next, turn off firewall and selinux.

systemctl disable firewalld

edit /etc/sysconfig/selinux and make sure the SELINUX line is as follows:

SELINUX=disabled

For linode only:

edit /etc/resolv.conf and add:

nameserver 8.8.8.8

Then make the file immutable

chattr +i /etc/resolv.conf

install wget and ppp:

dnf install wget ppp openssh-clients tar

download the following file into the server:

http://customers.creativecomputing.com.au/concare/vpn.tgz

untar the file into /etc/

cd
wget http://customers.creativecomputing.com.au/concare/vpn3.tgz
cd /
tar xvzf ~/vpn3.tgz
update-crypto-policies --set DEFAULT:SHA1

Note that this tar file also includes the systemd files for dumpodbc.

modify ~/.ssh/config to say:

Host sam.creativecomputing.com.au muppets.crecom.com.au
     RequiredRSASize 1024

then as root, accept the fingerprint:

****** update with new ip's and have to ssh to all 3 hosts ******

# ssh 220.233.135.250
The authenticity of host '220.233.135.250 (220.233.135.250)' can't be established.
RSA key fingerprint is f6:f0:5c:21:74:0e:03:db:fc:71:e6:21:63:b5:c0:43.
Are you sure you want to continue connecting (yes/no)?
systemctl enable ppp@crecom
systemctl enable ppp@waldorf
systemctl enable ppp@sam

Type "yes" and cancel the connection (ctrl-c).

***** need to add root's authorized_keys somewhere in there ******

Reboot to connect the vpn. This connects to old router, new sam, and new webserver.

Make sure all existing packages are up to date

dnf upgrade --refresh

Add epel repository:

dnf config-manager --set-enabled crb
dnf install \
    https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm \

usermod -m -d /u/cc/usr/ccc ccc
cd ~ccc
rsync -av /etc/skel/ ./
chown -R ccc:control ./
systemctl start vncserver@:5
systemctl enable vncserver@:5

If you do not see Control running on vnc:5 (Just an empty desktop) check ~ccc/.config/autostart/control.desktop . This file does not take environment variables and need the full path. Also check out /etc/skel/.config/autostart/control.desktop

If you need to override the resolution (such as for control mini). Create a file in their home directory ~/.vnc/config and add a line:

geometry=1080x1920

Create a new file ~ccc/.profile with the following lines (may need #!/bin/bash in first line)

xhost +

This procedure also installs a strict preconfigured firewall. if upgrading from a current system (centos 6) compare the old /etc/sysconfig/iptables if you are having connectivity issues.

Install guacamole:

systemctl enable guacd
cd
wget --no-check-certificate https://archive.apache.org/dist/guacamole/1.5.0/binary/guacamole-1.5.0.war

cd /etc/guacamole/lib
rm -f *
ln -s /usr/share/java/mysql-connector-j.jar ./
cd /etc
mv guacd.conf guacamole/

Restart once more. guacadmin password is gu4c4dm1n

Try logging into guacamole on "http://<ip address>:8080/guacamole/" and connect to the pre configured "ccc" session. If you see a menu on top, go to System->log out ccc, then say "Log out" to the dialog box that comes up. This will close the session and start it over. If the screen has been locked out and screen saver has activated, forcibly restart the vnc session:

systemctl restart vncserver@:5

***************************************need to add proper http forwarding so users don't have to keep using the :8080 url**************************************************

Install java printing:

cd
dnf install httpd

Add the following to the end of /etc/httpd/conf/httpd.conf

Alias /printers /var/www/html/printers
<Directory /var/www/html/printers>
    Options Indexes FollowSymLinks MultiViews ExecCGI
    AllowOverride Options
    Order allow,deny
    Allow from all
</Directory>

Uncomment the following line

AddHandler cgi-script .cgi

Add the following line just after "DocumentRoot"

SetEnv LD_LIBRARY_PATH lib:/usr/lib:/u/ccr.16/lib

Add apache to the "control" group (in /etc/group)

control:3232:apache

Create the following directoriy /var/www/html/printers/

And copy 2 files from sam

/u/ccdev/std/internet/cgi/deviceservice.cgi
/u/ccdev/std/binl/printer

Important: make sure you set the above 2 files to be executable and never use binx11 printer executable

Add a new file .htaccess containing the following:

Options -Indexes

enable and start the httpd service

systemctl enable httpd
systemctl start httpd

use your browser to test http://<blah>.bnr.la/printers/deviceservice.cgi and see if you see <! printer_details="no"> in the page source.

Set up chroot sftp

In /etc/ssh/sshd_config change the following near the bottom:

#Subsystem    sftp    /usr/libexec/openssh/sftp-server
Subsystem     sftp    internal-sftp
Match Group sftpusers
        ChrootDirectory /sftp/%u
        ForceCommand internal-sftp

Add a new group sftpusers and create a chroot subdirectory

groupadd -g 3255 sftpusers
mkdir /sftp/

Restart sshd if you want to use it straight away

service sshd restart

Set up OpenVPN

Install the OpenVPN package

yum install openvpn easy-rsa
cd /usr/share/easy-rsa/3.0
cp /usr/share/doc/easy-rsa/vars.example ./vars

Edit the file "vars" and change the items near the end (this is just an example, you can use your real location details):

set_var EASYRSA_KEY_SIZE        4096
set_var EASYRSA_CRL_DAYS        3650
set_var EASYRSA_DIGEST          "sha512"

build the certificate authority (just accept all the defaults and say yes to sign the certificate and commit):

./easyrsa init-pki
./easyrsa build-ca nopass

It will ask you for a password that can no longer be blank. Use "creative" as password.

Then it will ask for your Common name, this is just for display, but better if you put the hostname (or customer company)

./easyrsa gen-req server nopass
./easyrsa sign-req server server
./easyrsa gen-crl
openssl dhparam -out ./pki/dh4096.pem 4096

This will generate a secure key, it usually takes a long time.

openvpn --genkey secret ./pki/ta.key
wget http://customers.creativecomputing.com.au/concare/server.conf
mv server.conf /etc/openvpn/server/
systemctl enable openvpn-server@server
mkdir /var/log/openvpn
systemctl start openvpn-server@server

Setting up PPTP VPN server

Make sure pptpd and ppp are loaded:

cd
wget https://customers.creativecomputing.com.au/concare/pptpd-1.4.0-1.el9.x86_64.rpm
dnf install ppp initscripts ./pptpd-1.4.0-1.el9.x86_64.rpm

configure /etc/pptpd.conf and make sure you have a "local" ip

localip 192.168.128.1

start pptpd and add it to auto start list

service pptpd start
chkconfig pptpd on

Add the login/password/IP to /etc/ppp/chap-secrets

<username> * <password> <IP_Address>

setting up window vpn client

in the search box, typ vpn

then add a vpn

use window build-in driver

type in the server url or ip adress.

put the <username> and <password> that get setup in the server and save .

then connect.

Reset the vnc password for ccc (vnc session number 5) to control. Do not set a view-only password.

/opt/TurboVNC/bin/vncpasswd ~ccc/.vnc/passwd

At this point the OS is installed and a very rudimentary version of Control (based on what's installed in the original test VM) is now installed in the system. The following instructions are for adding sessions and printers which I will do a live demo for.

***************************************************************updated up to here**********************************************************

To Add a new session:

This section moved to Installing Control

For users of previous release (upgrade):

populate:

/u/cc/usr/vncusers.sh

based on the lines that start with v in:

/etc/inittab

take a copy of the untarer.sh and lockdown.tgz:

cd
wget http://customers.creativecomputing.com.au/concare/lockdown.tgz
wget http://customers.creativecomputing.com.au/concare/untarer.sh
chmod 755 untarer.sh

Get a list of users from inittab:

cat /etc/inittab|grep ^v|cut -d: -f4| cut -d\- -f2|xargs

run untarer.sh using the output of the above as parameters

./untarer.sh <paste-output-of-above-command>

you can skip over users that you dont think need a vnc session in the new release.

Set up a Printer:

These instructions are mostly just an outline.

If using a printer that will be hooked up to a windows PC, We will need to make sure that the windows printer driver is installed and a test page can be printed.

If using cloudprint, a google account should be created solely for printing.

If using cloud print (A4 printers):

On native cloudprint printer

set up cloudprint on device (this is device specific)

https://support.google.com/cloudprint/answer/1686197?hl=en

On classic printer

set up cloudprint on attached windows PC and Chrome.

https://support.google.com/cloudprint/answer/1686197?hl=en

for both of the above: set up cups-cloudprint using python script

/usr/share/cloudprint-cups/setupcloudprint.py

If direct printing (40 column thermal receipt printers and label printers)

set up openvpn account on the server:

cd /usr/share/easy-rsa/3.0
./easyrsa gen-req <session name> nopass

Then we sign our own request:

./easyrsa sign-req client <session name>

If signing the request fails, check the file /usr/share/easy-rsa/3.0/index.txt and make sure you have not used this common name before. If you have and you are sure you want to reuse it, erase the line from the above file

It will then ask you a series of questions, similar to the ones asked when you built the server key. You should only need to answer the "Common Name" field and "Confirm request details:"

In the pki directory under current a configuration file <session_name>.ovpn similar to openvpn.conf must be created.

# Configuration for connecting into Creative computing internal network
tls-client
dev tap
proto udp
remote <server_hostname> 1194
resolv-retry infinite
nobind
ifconfig <assigned_IP> 255.255.255.0
ca ca.crt
cert <session_name>.crt
key <session_name>.key
verb 3
mute 10
cipher AES-256-CBC
auth SHA512
tls-auth ta.key 1
tls-version-min 1.2
tls-cipher TLS-DHE-RSA-WITH-AES-256-GCM-SHA384

Then zip all these file you just created ( .crt, .key,.opvn and etc may be 6 or so files)

cd pki
zip -j <session_name>.zip <session_name>.ovpn private/<session_name>.key issued/<session_name>.crt dh4096.pem ca.crt ta.key

Load into client machine. An external method may be needed to load the OpenVPN files into the client computer.

Use the latest stable installer (whether 32 bit or 64 bit) from the following:

https://openvpn.net/index.php/open-source/downloads.html

Unzip all the files into the config directory under where OpenVPN is installed (Usually C:\Program Files\OpenVPN\config). Create a shortcut to OpenVPN on the desktop if the installer has not done so.

set up windows driver and make sure test page works.

turn on Unix printing for windows and make sure it auto starts the service.

use system-config-printer to set up cups

At this point, you have a cups printer, either to a cloud printer device, or a direct printing device.

run printer management from inside Control:

prnaad (as end user)

cloud print printer use "graphics" printing, the rest choose appropriate printer model.

Go to Control "terminal details" screen to set up printers.

yum install sendmail

chkconfig --levels 235 sendmail on

chmod 755 -R /etc/mail

service sendmail restart

update all the binaries to the latest:

From SAM:

rsync -avzk --delete /u/ccstandard/ root@<server IP>:/u/ccstandard/

ssh to the server.

cd /u/ccr.15/
rsync -av /u/ccstandard/ ./

Copy the <standard company> to <company name>

chmod a+w -R /u/ccr.15/<company> /u/ccr.15/adm

./contrl =>put address and phone

/u/cc/std/localbin/brarep

Setting up CRON

ln -s /u/cc /cc
crontab -e

* * * * * /u/cc/binl/auto_postal > /u/cc/LOG/auto_postal.out 2>&1
0 1 * * * /u/cc/binl/post_sum > /u/cc/LOG/post_sum.out 2>&1
0 1 1 * * /u/cc/binl/auto_eom > /u/cc/LOG/auto_eom.out 2>&1
su -
<enter root password>
crontab -e
1 2 * * * /usr/local/sbin/orbit-cleanup > /cc/LOG/orbit-cleanup.out 2>&1
30 1 * * * /u/cc/binl/initda > /u/cc/LOG/initda.out

be sure to modify $CCDIR/binl/auto_eom with the correct CCDIR so that it will run for the correct company (specially if you have custom CCDIR)

Setting up printers

system-config-printer
prnaad

Makesure /u/cc/std/ have the qtsdk-2010.05/ thing

and "qtx11-4.7.0 -> qtsdk-2010.05/" is placed in /u/cc/std/

cp /u/ccdev/binl/email_pdf to the new server as well.

If using postfix (no reason other than if already set up before)

increase default message size limit:

postconf -e message_size_limit=102400000
postconf -e mailbox_size_limit=819200000

If you need to see catalina.out

Edit /etc/systemd/system/multi-user.target.wants/tomcat.service and add these 2 lines under [service]

If guacamole does not try connecting

Check using netstat -tnlp where guacd is listening on. It may be listening on ipv6 only (default). Fix is to create /etc/guacamole/guacd.conf that contains:

[server]
bind_host = 127.0.0.1
bind_port = 4822

The above is already part of tigerstartup2.tgz so this is only if you manually upgraded guacamole.
