===== Installation =====
==== Kernel ====
{{Kernel|2.6.28-gentoo-r1|0@@}}
==== Installed Software ====
Also see:
* [[Linux#Essential software packages]]
* [[Framebuffer]]
Install the following packages:
* {{Package|direct=yes|net-misc/openssh}}
* {{Package|direct=yes|net-misc/bridge-utils}}
* {{Package|direct=yes|net-firewall/iptables}}
* {{Package|direct=yes|net-analyzer/tcpdump}}
* {{Package|direct=yes|net-nds/openldap}}
* {{Package|direct=yes|sys-auth/nss_ldap}}
* {{Package|direct=yes|sys-auth/pam_ldap}}
* {{Package|direct=yes|net-fs/samba}}
* {{Package|direct=yes|net-misc/ntp}}
* {{Package|direct=yes|dev-db/mysql}} {{USEFlag|{{EnableFlag|minimal}}}}
* {{Package|direct=yes|dev-util/subversion}}
* {{Package|direct=yes|mail-mta/postfix}}
* {{Package|direct=yes|app-crypt/aespipe}}
* {{Package|direct=yes|sys-power/cpufrequtils}}
==== Framebuffer splash ====
Configure the kernel and install the necessary packages as above, then build the kernel using:
{{Root|
genkernel --splash=natural_gentoo --splash-res=1280x1024 all
}}
Edit the grub config to contain the following kernel options:
{{File|/boot/grub/grub.conf|
title Gentoo Linux 2.6.29
root (hd0,0)
kernel /boot/kernel-genkernel-x86_64-2.6.29-gentoo root=/dev/ram0 real_root=/dev/mapper/badger-root ramdisk=8192 init=/linuxrc doscsi dolvm video=uvesafb:mtrr:3,ywrap,1280x1024@60 splash=verbose,fadein,theme:natural_gentoo console=tty1
initrd /boot/initramfs-genkernel-x86_64-2.6.29-gentoo
}}
Finally, add fbcondecor to the boot runlevel, and reboot
{{Root|
rc-update add fbcondecor boot
}}
===== Configuration =====
==== NTP ====
Set the clock on boot, and keep it up to date against any drift:
{{Root|
rc-update add ntp-client default
rc-update add ntpd default
/etc/init.d/ntp-client start
/etc/init.d/ntpd start
}}
==== Logging ====
Badger hosts central network logging. See [[Syslog]] for configuration.
==== LDAP ====
See [[LDAP/Openldap]]. Configuration files are stored in subversion, under [[https://dev.sihnon.net/svnpriv/configs/ldap/client|configs:/ldap/client/]].
==== Mail ====
Edit /etc/postfix/main.cf to set the hostname. As this host is not a primary or backup MX, no other configuration is necessary.
{{Root|1@@}}
==== Samba ====
Configuration is stored in subversion, under [[https://dev.sihnon.net/svnpriv/configs/samba/client|configs:/samba/client]]. Samba's LDAP password must be set to the same value stored in the directory and then the service can be started.
{{Root|2@@}}
==== Wireless ====
See [[Wireless]]. Configuration is stored in subversion, under [[https://dev.sihnon.net/svnpriv/configs/wireless/badger/|configs:/wireless/badger/]].
==== VMWare Server ====
Add the vmware overlay, which contains packages for vmware-server 2.x.
{{Root|
layman -a vmware
}}
Then install the following packages
* {{Package|direct=yes|app-emulation/vmware-server}}
* {{Package|direct=yes|app-emulation/vmware-modules}}
Run the vmware-config script to compile the proper modules and configure the networking. Set up the network as follows:
* vmnet0
* name: public
* type: bridged
* bridged to: eth0
* vmnet1
* name: local
* type: bridged
* bridged to: br1
Install the following packages to be able to connect to pipes mapped to virtual serial ports:
* {{Package|direct=yes|socat}}
* {{Package|direct=yes|taylor-uucp}}
==== iSCSI ====
Set up badger to host targets as in [[ISCSI#Server]]. Create one LVM partition for each virtual machine, and configure ietd.conf to share each of them.

===== Vista =====
Badger will not sleep properly under vista by default; it will always wake up within seconds of powering off.
To fix this:
* Control Panel/Administrative Tools/Computer Management
* Device Manager/Network adapters/Marvell Yukon/Properties/Advanced
* Wake from Shutdown => On
* Wake Up Capabilities => Magic Packet only
