Installing Oracle Java

Mark: Here come dat "you cant post links" message again :/

Using java requires having grsec play nice with the binaries. You may also want to install the JDK instead of the JRE depending on your use case.

This guide assumes you're running as root.

Download XXX-XXX-linux-x64.tar.gz from either the JRE or JDK section here:
htt$p://www.oracle.com/technetwork/java/javase/downloads/index.html

mkdir -p /opt/java
cd /opt/java
sudo tar -zxvf XXX-XXX-linux-x64.tar.gz

Note down the directory, e.g. /opt/java/jdk1.8.0_121, create a symbol link as the current version:

ln -s /opt/java/jdk1.8.0_121 /opt/java/current

Create a file in '''/etc/profile.d/java.sh''':
export JAVA_HOME=/opt/java/current
export PATH=$PATH:$JAVA_HOME/bin

Execute this script or restart your shell:
sh /etc/profile.d/java.sh

Now we need manage grsec with paxctl use this command to check if its installed:
which paxctl

If nothing comes up install it:

apk add paxctl

Now in your /opt/java/XXX/bin folder let it execute:
paxctl -c java
paxctl -m java

If you have the JDK, you need to do the same to javac:
paxctl -c javac
paxctl -m javac

You can do this for any other binary you need to use.

NOTE: I read online that some people required using this command to get it working (and it may be a better alternative):

setfattr -n user.pax.flags -v "mr" java
setfattr -n user.pax.flags -v "mr" javac

This document describes how to set up a wireless network connection with WPA encryption.

First make sure your wireless drivers are loaded properly. (if you are using a '''Broadcom chipset''', see the [[#Broadcom_Wi-Fi_Chipset_Users|section at the bottom of this post]].)

Install {{Pkg|wireless-tools}} and {{Pkg|wpa_supplicant}}.
{{Cmd|apk add wireless-tools wpa_supplicant}}

Bring the link up so we can look for wireless networks. (An error here means you probably need extra drivers/firmware.)
{{Cmd|ip link set wlan0 up}}

Find a network to connect to. Look for the ESSID. In this example we will use the ESSID "MyNet".
{{Cmd|iwlist wlan0 scanning}}

Let's set the ESSID:
{{Cmd|iwconfig wlan0 essid MyNet}}

We need to create a shared key for wpa_supplicant.
{{Cmd|wpa_passphrase MyNet > wpa.conf}}
It will wait for the password from stdin. Enter the password and enter. Now you will have a {{Path|wpa.conf}} file with the preshared key.

Start wpa_supplicant with the generated config:
{{Cmd|wpa_supplicant -Dwext -iwlan0 -c ./wpa.conf}}

From another console, start dhcpcd:
{{Cmd|udhcpc -i wlan0}}

You should get an IP address.

You then want to make the connection process automatic on boot-up. Open {{Path|/etc/network/interfaces}} and add the following stanza:
auto wlan0
iface wlan0 inet dhcp
{{Note|I had to append `pre-up iwconfig wlan0 essid <ESSID>` to automatically connect to the network.}}

You will also need to set wpa_supplicant to start automatically on boot:
{{Cmd|rc-update add wpa_supplicant boot}}

Next, create {{Path|/etc/wpa_supplicant/}} (permissions of 755 with root:root are fine), and move {{Path|wpa.conf}} into that folder, renaming it to {{Path|wpa_supplicant.conf}}.

Reboot and check that you are associated with the access point:
{{Cmd|iwconfig wlan0}}
and check that you got a DHCP lease:
{{Cmd|ifconfig wlan0 {{!}} grep addr}}

== Broadcom Wi-Fi Chipset Users ==
The Broadcom chipset is quite popular among older computers. You will need to compile the firmware manually for this chipset as it is not included.

You can check if you have a Broadcom chipset by using dmesg:

{{Cmd|dmesg {{!}} grep Broadcom}}

First install the SDK an Git:
{{Cmd|apk add alpine-sdk git}}

Then git clone aports from git.alpinelinux.org.

(remove $, new users can't add links to the wiki)

{{Cmd|git clone git:/$/git.alpinelinux.org/abuild}}

Change your directory to '''aports/non-free/b43-firmware''', then build it.

''You can't be root and must be a user of the group abuild (use groupadd)''

{{Cmd|abuild -r}}

Install the generated packge file (it will be in ~/packages/) - make sure to pass '''--allow-untrusted'''

{{Cmd|apk add --allow-untrusted ~/packages/...pkg}}

Now we need fwcutter, which is executed from the firmware package:

{{Cmd|apk add b43-fwcutter b43-firmware}}

Now you need to use modprobe so the device will show up:

{{Cmd|modprobe b43}}

To automate this on startup add it to /etc/modules:

{{Cmd|echo b43 >> /etc/modules}}

Now continue with the normal instructions.

Mark: /* An unfortunate mix */

== The way I do it ==

I created the passphrase as described and moved it to /etc/wpa_supplicant/wpa_supplicant.conf and did rc-update add wpa_supplicant. Then I let dhcpcd service handle the wlan0 interface, bascially, keep only the lo interface in /etc/network/interfaces and then start dhcpcd service. --[[User:Ncopa|Ncopa]] 08:19, 25 January 2011 (UTC)

== An unfortunate mix ==

This page is an unfortunate mix of how bring up a wireless interface on a running system vs. how bring up a wireless interface at boot time. Those topics should be discussed separately and they are not. It's possible to tease the information out of this, but it's much more difficult than it should be.

:I agree, same goes with 'Broadcom Wi-Fi Chipset Users' which I just updated. It can stay on the same page, but it should be separated into sections? --[[User:Mark|Mark]] ([[User talk:Mark|talk]]) 04:20, 18 March 2017 (UTC)

== Broadcom Wi-Fi Chipset Users ==
The Broadcom chipset is quite popular among older computers. You will need to compile the firmware manually for this chipset as it is not included.

First install the SDK an Git:
{{Cmd|apk add alpine-sdk git}}

Then git clone aports from git.alpinelinux.org. You can't be root and must be a user of the group abuild (use groupadd).

(remove $ signs, new users can't add links)

{{Cmd|git clone git:$/$/gi$t.alpinelinux.$org/abuild}}

Change your directory to '''aports/non-free/b43-firmware''', then build it:

{{Cmd|abuild -r}}

Install the generated packge file (it will be in ~/packages/) - make sure to pass '''--allow-untrusted'''

{{Cmd|apk add --allow-untrusted ~/packages/...pkg}}

Now we need fwcutter, which is executed from the firmware package:

{{Cmd|apk add b43-fwcutter b43-firmware}

Now you need to use modprobe so the device will show up:

{{Cmd|modprobe b43}}

To automate this on startup add it to /etc/modules:

{{Cmd|echo b43 >> /etc/modules}}

Now continue with the normal instructions.

Wi-Fi

Mark: Some real info for the users with the unfortunate Broadcom Wi-Fi Chipset. 2 hours of internet searching led me to this, enjoy. <3

This document describes how to set up a wireless network connection with WPA encryption.

First make sure your wireless drivers are loaded properly. (if you are using a Broadcom chipset, see note at the end of this post.)

Install {{Pkg|wireless-tools}} and {{Pkg|wpa_supplicant}}.
{{Cmd|apk add wireless-tools wpa_supplicant}}

Bring the link up so we can look for wireless networks. (An error here means you probably need extra drivers/firmware.)
{{Cmd|ip link set wlan0 up}}

Find a network to connect to. Look for the ESSID. In this example we will use the ESSID "MyNet".
{{Cmd|iwlist wlan0 scanning}}

Let's set the ESSID:
{{Cmd|iwconfig wlan0 essid MyNet}}

We need to create a shared key for wpa_supplicant.
{{Cmd|wpa_passphrase MyNet > wpa.conf}}
It will wait for the password from stdin. Enter the password and enter. Now you will have a {{Path|wpa.conf}} file with the preshared key.

Start wpa_supplicant with the generated config:
{{Cmd|wpa_supplicant -Dwext -iwlan0 -c ./wpa.conf}}

From another console, start dhcpcd:
{{Cmd|udhcpc -i wlan0}}

You should get an IP address.

You then want to make the connection process automatic on boot-up. Open {{Path|/etc/network/interfaces}} and add the following stanza:
auto wlan0
iface wlan0 inet dhcp
{{Note|I had to append `pre-up iwconfig wlan0 essid <ESSID>` to automatically connect to the network.}}

You will also need to set wpa_supplicant to start automatically on boot:
{{Cmd|rc-update add wpa_supplicant boot}}

Next, create {{Path|/etc/wpa_supplicant/}} (permissions of 755 with root:root are fine), and move {{Path|wpa.conf}} into that folder, renaming it to {{Path|wpa_supplicant.conf}}.

Reboot and check that you are associated with the access point:
{{Cmd|iwconfig wlan0}}
and check that you got a DHCP lease:
{{Cmd|ifconfig wlan0 {{!}} grep addr}}
