Broadcom BCM43142 on Ubuntu 13.04 64bit

download the file: http://jas.gemnetworks.com/debian/po...19-1_amd64.deb
sudo apt-get install linux-headers-generic build-essential dkms
then install the debian package
but you need to install the following stuffs for 13.04
- linux-headers-generic
- bcmwl-kernel-source
then you can use wifi!
ps: This document is just integrate some contents from the other sites.

where is the Firefox default settings, like cookies

In /home/username/.mozilla/firefox there has a file named "profiles.ini".
This file contains the [Profile0], and that defines which folder will be used for default settings, use "abc" to be example.
That means /home/username/.mozilla/firefox/abc will have lots of files about the firefox settings.
Like cookies, the file is "cookies.sqlite".

Change wireless on/off status in general user mode

list some different ways, but need to verify by yourself carefully.

1. silly way....killall nm-applet

2. /etc/acpi/wireless.sh

3. script file by Paul Liu
For old/new version (remark lines are for old version)
#!/bin/sh

#dbus-send --system --type=method_call \

Command line wireless enablement

It's just refer to someone readme file, but properly useful when no GUI.

"ifconfig wlan0 up"
"ifconfig" to check the "wlan0" section
"iwlist scan" to scan all AP (The essid "testap" for example)
"iwconfig wlan0 essid testap" to set up essid
"ifconfig wlan0 broadcast 192.168.0.255 netmask 255.255.255.0 192.168.0.100"
"route add default gw 192.168.0.1 dev wlan0"

socket與協定的觀念 - 以nc與http為例

port這東西有時候好像很難解釋, 但如果透過實際的操作就很好理解
先在該台主機上要產生一個192.1.1.1:1111的門,也就是socket, 讓大家可以連線
nc -l 192.1.1.1 1111
可以在另一台主機上使用
telnet 192.1.1.1 1111
這樣就可以雙方進行對話

因此協定的目的, 就在讓雙方可以透過socket進行"對話", 對話的規範就叫協定
像Web Server, 其實是可以透過telnet的方式將網頁抓回來
只是要知道HTTP協定的對話模式, 以及對方應有的網頁檔名
簡單的可以用下面的範例
telnet 192.1.1.1 80
進入後再輸入
GET /index.html
就可以看到index.html的內容

Solaris DHCP server configuration tips

#hostname pxeserver

Start and Stop DHCP service
dhcpconfig -S -d <-- stop dhcpconfig -S -e <-- start PXE default settings # dhtadm -A -m PXEClient:Arch:00000:UNDI:002001 -d ':BootSrvA=192.1.1.254:' Create options # dhtadm -A -s SrootIP4 -d ’Vendor=SUNW.i86pc,2,IP,1,1’ # dhtadm -A -s SrootNM -d ’Vendor=SUNW.i86pc,3,ASCII,1,0’ # dhtadm -A -s SrootPTH -d ’Vendor=SUNW.i86pc,4,ASCII,1,0’ # dhtadm -A -s SinstIP4 -d ’Vendor=SUNW.i86pc,10,IP,1,1’ # dhtadm -A -s SinstNM -d ’Vendor=SUNW.i86pc,11,ASCII,1,0’ # dhtadm -A -s SinstPTH -d ’Vendor=SUNW.i86pc,12,ASCII,1,0’ # dhtadm -A -s SsysidCF -d ’Vendor=SUNW.i86pc,13,ASCII,1,0’ # dhtadm -A -s SjumpsCF -d ’Vendor=SUNW.i86pc,14,ASCII,1,0’ # dhtadm -A -s SbootURI -d ’Vendor=SUNW.i86pc,16,ASCII,1,0’ Add a PXE client # ./add_install_client -d -e "00:a0:d1:e1:a5:3d" \ <-- Client's MAC address # > -s 192.1.1.1:/export/home/sol10 \
# > i86pc
Create private macro for MAC
# dhtadm -A -m 0100A0D1E1173C -d ':SinstNM=192.1.1.254:SinstIP4=192.1.1.254:SinstPTH=/export/home/sol10_ga:SrootNM=client:SrootIP4=192.1.1.254:SrootP

# pntadm -A 192.1.1.100 192.1.1.0
# pntadm -M 192.1.1.100 -m 0100A0D1E1173C 192.1.1.0

Solaris PXE server installation and configuration

DHCP
1. /usr/sadm/admin/bin/dhcpmgr command under GUI
2. Now finish configuring DHCP service
3. You can start and stop service by this tool


NFS Image files
1. create /export/home/sol10 directory
2. insert the first CD in the CDROM. Go to /cdrom/cdrom0/s2/Solaris_10/Tools
3. Execute the following command:
# ./setup_install_server /export/home/sol10
4. After finishing the CD1, change to another disk step by step(CD2,3,4) and into the same directory
5. Execute the following command:
# ./add_to_install_server /export/home/sol10


NFS
1. Edit /etc/dfs/dfstab file and add a following line.
share –F nfs –o ro,anon=0 –d "install server directory” /export/home/sol10
2. Do "shareall" command
3. Type "share" command to see if it works.
4. Do command "svcadm enable network/nfs/server"
5. "showmount -e" to see if it works or check "ps -efgrep nfs".
6. If not, do it by yourself like below.
/usr/lib/nfs/nfsd -a
/usr/lib/nfs/statd
/usr/lib/nfs/nfsmapid
/usr/lib/nfs/lockd
/usr/lib/nfs/mountd
7. It should be work now. If not, call the police.....:)


PXE and DHCP
1. Get into /export/home/sol10/Solaris_10/Tools
2.
# ./add_install_client -d -e "00:a0:d1:e1:a5:3d" \ <-- Client's MAC address # > -s 192.1.1.1:/export/home/sol10 \
# > i86pc

$$$$ It shows some messages and VERY IMPORTANT about the PXE function.

3.
Do following command to make the same option for dhcp.
# dhtadm -A -s SrootIP4 -d ’Vendor=SUNW.i86pc,2,IP,1,1’
# dhtadm -A -s SrootNM -d ’Vendor=SUNW.i86pc,3,ASCII,1,0’
# dhtadm -A -s SrootPTH -d ’Vendor=SUNW.i86pc,4,ASCII,1,0’
# dhtadm -A -s SinstIP4 -d ’Vendor=SUNW.i86pc,10,IP,1,1’
# dhtadm -A -s SinstNM -d ’Vendor=SUNW.i86pc,11,ASCII,1,0’
# dhtadm -A -s SinstPTH -d ’Vendor=SUNW.i86pc,12,ASCII,1,0’
# dhtadm -A -s SsysidCF -d ’Vendor=SUNW.i86pc,13,ASCII,1,0’
# dhtadm -A -s SjumpsCF -d ’Vendor=SUNW.i86pc,14,ASCII,1,0’
# dhtadm -A -s SbootURI -d ’Vendor=SUNW.i86pc,16,ASCII,1,0’

4. And then use “/usr/sadm/adm/bin/dhcpmgr&” to call the GUI programe to configure following items.
5. Create 2 macros as it said. (0100xxxxxx and the PXEClientxxxxx)
6. Create the Address FOR the macro.
7. Now finish configuring DHCP with PXE service
8. You can start and stop service by this tool


Trouble Shooting
1. If cannot boot from the client and cause by the driver.
a. Modify path
/export/home/sol10/Solaris_10/Tools/Boot/boot/solaris/devicedb/master
Change driver name from none to “bge.bef” or something like that.
b. Modify path
/export/home/sol10/Solaris_10/Tools/Boot/etc/driver_aliases
Add a line bge “pci14e4,16a8” <-- It shows on your client’s error message. 2. If cannot put into the CDs, please do following command in CLI mode. # svcadm enable smserver 3. The command “lspci” usage in Solaris # prtconf –pv

[no]: no
Would you like to share to Windows clients (yes/no/?) [no]: yes

You will now be prompted for the Samba configuration:
Samba share name: clushare

The samba config file /etc/samba/smb.conf.clushare does not exist.

Would you like a default config file created (yes/no/?) [no]: yes

Successfully created /etc/samba/smb.conf.clushare.
Please remember to make necessary customizations and then copy the file
over to the other cluster member.

Do you want to (a)dd, (m)odify, (d)elete or (s)how DEVICES, or
are you (f)inished adding DEVICES [f]: f
name: clusamba
preferred node: node2
relocate: yes
user script: None
monitor interval: 90
IP address 0: 10.1.1.254
netmask 0: None
broadcast 0: None
device 0: /dev/sdb1
mount point, device 0: /mnt
mount fstype, device 0: ext2
mount options, device 0: rw,nosuid,sync
force unmount, device 0: yes
samba share, device 0: clushare
Add clusamba service as shown? (yes/no/?) yes


Test procedure:
You can reboot or shutdown one of these 2 nodes and observe the smb daemon in another node.
#smbclient -L 10.1.1.254
You have to see a sharename with "clushare" and Comment is "High Availability Samba Service" and done.

Use iscsi driver to integrate NAS storage in Linux system

##### Environment Settings############
OS: RedHat AS2.1 u5
Kernel: 2.4.9-e.49smp
rpm file: clumanager-1.0.27-1

node1 --> 10.1.1.101
node2 --> 10.1.1.102
Service IP --> 10.1.1.254 (Public IP)
################################

#### iSCSI settings with NAS Storage #########
Install NAS with linux-iscsi-.tgz from http://sourceforge.net/index.php
uncompress the file and into the iscsi directory
make
make install
Do next 3 steps

#vi /etc/iscsi.conf
----------------------------------------------------------------------
DiscoveryAddress=10.1.1.1:3260 --> your NAS' IP and port number
----------------------------------------------------------------------

#vi /etc/initiatorname.iscsi
----------------------------------------------------------------------------
InitiatorName=host1--> your NAS’ share hosts name
---------------------------------------------------------------------------

#/etc/init.d/iscsi start
You should find out your NAS share disk in /proc/partition as /dev/sda
##########################################



####### raw devices settings ##########
fdisk /dev/sda as /dev/sda1 and /dev/sda2
***Don't use mke2fs or something to format these 2 partition.***
Modify /etc/sysconfig/rawdevices file to add:
/dev/raw/raw1 /dev/sda1
/dev/raw/raw2 /dev/sda2
/etc/rc.d/init.d/rawdevices start
Until now your 2 raw devices are workable.
##########################################


########## Cluster HA settings #########
You can use relative softwares like clu* to manage cluster members.
*** The sample settings below focus on node1, if you use node2 will be reversed.
#cluconfig
Enter cluster name: ha1
Enter IP address for cluster alias: 10.1.1.254 --> This is your service IP, NOT real IP for NIC.
---- Next step is configure your Member 0 --> yourself ----
Enter name of cluster member: node1
Enter number of heartbeat channels:1 --> We only use 1 NIC to connect to another node
Channel type:net
Enter hostname of the cluster member on heartbeat channel 0: node1
---- Next step is configure your raw devices ----
Enter Primary Quorum Partition: /dev/raw/raw1 --> such as your raw devices list in /etc/sysconfig/rawdevices
Enter Shadow Quorum Partition: /dev/raw/raw2 --> such as your raw devices list in /etc/sysconfig/rawdevices
Power switch: NONE

---- Next step is configure your Member 1 --> node2 ----
Enter name of cluster member: node2
Enter hostname of the cluster member on heartbeat channel 0: node2
---- Next step is configure its raw devices ----
Enter Primary Quorum Partition: /dev/raw/raw1 --> such as its raw devices list in /etc/sysconfig/rawdevices
Enter Shadow Quorum Partition: /dev/raw/raw2 --> such as its raw devices list in /etc/sysconfig/rawdevices
Power switch: NONE

*** It will save your configuration in /etc/cluster.conf
Remember if you want to remove the cluster.rpm file, delete the /etc/cluster.conf after you remove.
########################################


Now you can use ifconfig to show your NIC information.
It should add a virtual IP address eth0:0 as 10.1.1.254. --> Your service IP is in eth0:0.


Test procedure
1. Shutdown the node2 directly (power off).
2. Use ifconfig in node1 to observe if its NIC will add a eth0:0 directly.
3. It should less than 30 sec and under my testing is 15 sec.
