Lab Exercise #1: Linux and Windows Dual-Boot Installation
Following procedures in the LINUX installation guide, install the Gnome desktop version of LINUX on the assigned workstation with the following values:
1. Install Windows in the first 1/2 partition of your hardrive (see CIS 228 procedure)
2. Install Linux edition specified by instructor
Specify options as follows:
- Select English as the language
- Manual Partition /boot (4GB), root / (40GB), swap (5GB), /share (10GB), /home (20GB)
- GRUB Bootloader on Master Boot Record
- Configure IP for DHCP (see instructor):
Click Activate on Boot
Hostname: studentnn; nn is the workstation #.
- Configure TimeZone for US Central Time
- Set root password as “password” (ignore the doublequotes when typing the password)
- Select Office Productivity and Software Development, Select Customize Later Select options indicated by the Instructor
- Select yes on EULA
- Installation proceeds
4. Fedora Setup
- DISABLE firewall
- DISABLE SELinux
- Set Date and Time
- Set display
- Add account: “user1” with the same password as Root
- Select package components as specified by instructor
5. After installation completes, hit ENTER to reboot
6. At the Desktop login as user1 with a password of “password”
8. Add user1-user9 to both LINUX and Windows OS’es per procedure.
Password=”password”.
9. DISABLE FIREWALL and SELINUX !!!!!!!!! Use GUI.
Fedora 15: service iptables stop
Fedora 19: service firewalld stop
iptables –L, review output
ifconfig virbr0 down
ifconfig virbr0-nic down
-OR- remove docker and lxc packages
10. DISABLE IPv6!!!!!!:
Fedora 15:
sysctl -w net.ipv6.conf.all.disable_ipv6=1
service network restart
Fedora 19:
Add ipv6.disable=1 to the end of the LINUX line in grub.cfg. Reboot.
IPv6 note: Dual-stack applications which bind() sockets with address family AF_INET6 but without setsockopt() option IPV6_IPV6ONLY can do mapped IPv4 (0::FFFF:a.b.c.d/128 ) from their v6 socket as well as native IPv6 (2000::/3) A buggy dual-stack application like SAMBA or APACHE might try to do this, but fail - resulting in ports open on IPv6, but not IPv4. Turning off IPv6 avoids any buggy dual-stack application problems on IPv4. Not recommended in the future. Learn how to selectively disable services under IPv6 if needed.
