## Notes

## Code

## SSH-KEY

## Linux installs

`sudo apt-get install openssh-server`
`sudo apt-get install ssh openssh-client openssh-server`
`sudo apt install net-tools`

`ip address` -- for ip address
`ifconfig` -- for ip address

Switch to bridged networking mode, make that change in the Virtual Machine Control Panel (Edit > Virtual Machine Settings)

reboot the VM

`sudo apt install openbsd-inetd`
`cat ~/.ssh/id_rsa.pub`
`ssh-keygen -t rsa -b 4096 -C "Your email"`
`cat ~/.ssh/id_rsa.pub`
`sudo vim ~/.ssh/authorized_keys`
gg, dG - to clear all in vim
now copy the keys

### Windows (on bash):

`clip < ~/.ssh/id_rsa.pub`

### Mac:

`pbcopy < ~/.ssh/id_rsa.pub`

### GNU/Linux (requires xclip):

`sudo apt install xclip`
`xclip -sel clip < ~/.ssh/id_rsa.pub`

## Install Postfix

sudo apt-get update
sudo apt-get install postfix libsasl2-modules mailutils -y

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# line of that file to be used as the name.  The Debian default
# is /etc/mailname.

sudo vim /etc/mailname

Try restart process and then run below code.

echo "This is testing SMTP Relay." | mail -s "Postfix Mailgun" [e-mail]

sudo postfix check
sudo systemctl restart postfix
sudo service postfix restart
sudo netstat -lntp | grep master
sudo postmap /etc/postfix/virtual-regexp
sudo service postfix reload
tail -n 100 /var/log/mail.log

get test email checker from https://www.mail-tester.com

Add the given email to authorized email in the mailgun

echo "This is testing SMTP Relay. 3 " | mail -s "Postfix Mailgun 2" [Use that testing email]

## Install Gitlabs

sudo apt-get update
sudo apt-get install -y curl openssh-server ca-certificates tzdata
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh | sudo bash

sudo EXTERNAL_URL="https://gitlab.example.com" apt-get install gitlab-ee

### Restart Gitlabs

sudo gitlab-ctl restart

# Prevent users from writing to the repositories while you move them.
sudo gitlab-ctl stop

# Note there is _no_ slash behind 'repositories', but there _is_ a
# slash behind 'git-data'.
sudo rsync -av /var/opt/gitlab/git-data/repositories /mnt/nas/git-data/

# Start the necessary processes and run reconfigure to fix permissions
# if necessary
sudo gitlab-ctl reconfigure

# Double-check directory layout in /mnt/nas/git-data. Expected output:
# repositories
sudo ls /mnt/nas/git-data/

# Done! Start GitLab and verify that you can browse through the repositories in
# the web interface.
sudo gitlab-ctl start

## Permission Grant

sudo chmod a+rwx /etc/gitlab
