[Ubuntu] install ARP-scan

install arp-scan command:

sudo apt-get install arp-scan

Ubuntu 14.04.2 Server + BIND DNS Server + SIP DNS SRV settings

step 1.

Download Ubuntu Server 14.04.2 and install this system.
http://www.ubuntu.com/download/server


Installation process
To select the “DNS Server” service function.


step 2.

Install Webmin On Ubuntu 14.04 LTS using official repository

Add the webmin official repository:

Edit file /etc/apt/sources.list,

sudo nano /etc/apt/sources.list

Add the following lines:

 

deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib

Add the GPG key:

sudo wget http://www.webmin.com/jcameron-key.asc
sudo apt-key add jcameron-key.asc

Update the sources list:

sudo apt-get update

Install webmin using the following command:

sudo apt-get install webmin

Allow the webmin default port “10000” via firewall, if you want to access the webmin console from a remote system.

sudo ufw allow 10000

Access Webmin console

Open up your browser and navigate to the URL https://ip-address:10000/. The following screen should appear. Enter the user name and password to log in to webmin console.

step 3.

使用 Webmin方式來設定DNS Server

設定 Bind 8 可以接受外部連線及轉送查詢的伺服器。
「伺服器」->「BIND 8 DNS 伺服器」->「Edit Config File」->/etc/bind/named.conf.options
在此檔中加入
 
listen-on port 53 { any; };
forwarders {
        163.168.168.59;   //base DNS IP
        8.8.8.8;  //google DNS IP

        };
    allow-query {
        any;
        };

設定區域預設值

「伺服器」->「BIND 8 DNS 伺服器」->「區域預設值」
「預設的區域設定」->「允許從 ... 的查詢」點擊「監聽」及輸入 [any]
 






建立一個新的主控區域-正向
輸入管理網域名稱 test.local

 

建立 Address 紀錄(位址)

 增加 Address 紀錄
 

step 4.

使用nslookup指令查詢

nslookup
server "DNS Server IP"
set type=srv
_sip._udp.test.local

[Ubuntu]架IPv6 DHCP Server

sudo apt-get install isc-dhcp-server

1. set a static IPv6 address for the Interface I want to run the DHCPv6 server from that is part of the IPv6 network subnet outside the DHCP range.

2. Edit the /etc/dhcp/dhcpd6.conf file to configure the DHCPv6 range etc.

3. Create the /var/lib/dhcp/dhcpd6.leases

4. Manually start the DHCPv6 server.

----------------------------------------------------------------------------

sudo ifconfig eth0 inet6 add 2001:db8:0:1::128/64

[ configure dhcpd6.conf ]

default-lease-time 600;

[ubuntu]Install TFTP Server

sudo apt-get install tftpd-hpa tftp-hpa

sudo gedit /etc/default/tftpd-hpa

####################

#Defaults for tftpd-hpa

TFTP_USERNAME="root"

TFTP_DIRECTORY="/home/takashi/tftpboot"

TFTP_ADDRESS="0.0.0.0:69"

TFTP_OPTIONS="-l -s -c --secutre"

####################

PS:/home/takashi/tftpboot 需要自已新增目錄

sudo mkdir /home/takashi/tftpboot

sudo chmod 777 /home/takashi/tftpboot

sudo service tftpd-hpa start

在Ubuntu上面直接裝的TFTP server套件不會在開機時執行，精確一點說應該是開機時跑了卻沒有起來。

這是個老毛病，修一下就好。
編輯 /etc/init/tftpd-hpa.conf ，修改它錯誤的初始條件。

[Linux] ubuntu install telnet service

ubuntu安装telnet服务

1. sudo apt-get install xinetd telnetd

sudo gedit /etc/inetd.conf并加入以下一行，假如没有发现这个文件，

自己新建立一个也是可以的.
 ------------------------------------------------------------------------------------------------------------

telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd

 ------------------------------------------------------------------------------------------------------------

3. sudo gedit /etc/xinetd.conf并加入以下内容：

------------------------------------------------------------------------------------------------------------

# Simple configuration file for xinetd
#
# Some defaults, and include /etc/xinetd.d/

defaults
{
# Please note that you need a log_type line to be able to use log_on_success
# and log_on_failure. The default is the following :
# log_type = SYSLOG daemon info
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}

 ------------------------------------------------------------------------------------------------------------

4. sudo gedit /etc/xinetd.d/telnet并加入以下内容：

 ------------------------------------------------------------------------------------------------------------
# default: on
# description: The telnet server serves telnet sessions; it uses
# unencrypted username/password pairs for authentication.
service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}

[Linux]Pure-FTPD + pureadmin

Install ''Pure-FTPD'' with GUI

1. Install the pure-ftpd package and the pureadmin package from the Universe Repository.

sudo apt-get install pure-ftpd pureadmin  

2.新增虛擬使用者所要對應的系統使用者(ftpuser)與其家目錄
sudo adduser --system --home /home/ftpuser --shell /dev/null --disabled-password  --disabled-login ftpuser

3.新增虛擬使用者
sudo pure-pw useradd user01 -u ftpuser -d /home/ftpuser

如果要不同使用者有不同家目錄需在 -d 指定且新增其家目錄, 如
sudo mkdir /home/ftpuser/joe; sudo chown -R ftpuser /home/ftpuser/joe
sudo pure-pw useradd joe -u mis91 -d /home/ftpuser/joe
預設會新增在 /etc/pure-ftpd/pureftpd.passwd 中，或使用 pure-pw -f your.passwd.file 指定

4.建立 db 並確認 /etc/pure-ftpd/conf/PureDB 中資料為 /etc/pure-ftpd/pureftpd.pdb
sudo pure-pw mkdb /etc/pure-ftpd/pureftpd.pdb -f /etc/pure-ftpd/pureftpd.passwd

加入 DB 認証模式至設定中
sudo ln -s /etc/pure-ftpd/conf/PureDB /etc/pure-ftpd/auth/45puredb

5.確認幾項設定
* 確認 cat /etc/pure-ftpd/conf/UnixAuthentication 中指有字串 no
* 確認 cat /etc/pure-ftpd/conf/MinUID 中的數值比 ftpuser 的 UID 還小(如： adduser --system 的 UID 通常會預設值) , 不然虛擬帳號無法登入

6.重新啟動 pure-ftpd service
sudo /etc/init.d/pure-ftpd restart

============================================================
其他常用到的幾個設定，檔案都需寫在 /etc/pure-ftpd/conf 下
* ) echo "yes" > ChrootEveryone (使用者被限制在家目錄下)
* ) echo "no" > PAMAuthentication (不使用 PAM 認証：一般用者無法用 pure-ftpd 登入)
*) echo ",9188" > Bind (設定 ip/port )
* ) echo "yes" > KeepAllFiles (這個應該是不允許用戶端刪除文件)
* ) echo "yes" >DontResolve (不解釋主機名，可以加快登錄速度)

設定允許 symbolic links :
1) 編輯 /etc/default/pure-ftpd-common
將 VIRTUALCHROOT=false 改為 VIRTUALCHROOT=true
2) Restart service

設定允許 匿名登入
1) echo "no" > /etc/pure-ftpd/conf/NoAnonymous
2) sudo adduser --system --home /home/ftpuser --shell /sbin/nologin --disabled-password  --disabled-login  ftp
3) Restart service

設定 Passive mode
1) echo "29799 29899" > /etc/pure-ftpd/conf/PassivePortRange

 設定最多 clients 數量
1) echo "50" > /etc/pure-ftpd/conf/MaxClientsNumber

[Linux]Fix Lubuntu / Xubuntu 14.04 Network Manager Missing From The Panel

Lubuntu 14.04: fix 1

To fix the Network Manager not showing up on the panel issue, from the Lubuntu menu select Preferences > Default applications for LXSession, then click on the Autostart tab and under "Manual autostarted applications" type "nm-applet", then click the "+ Add" button on the left:

If the above solution didn't work for you in Lubuntu 14.04 or if you're using Xubuntu 14.04 and you're having this issue, here's another solution. Basically, the solution below is for those who must run "nm-applet" as root to get it to show up in the pane - we'll be using dbus-launch to launch nm-applet at startup.

To get the Network Manager applet to work properly in either Lubuntu 14.04 or Xubuntu 14.04, run the following command:

sudo sed -i 's/Exec=nm-applet/Exec=dbus-launch nm-applet/' /etc/xdg/autostart/nm-applet.desktop

[Ubuntu]Create VLAN in Ubuntu Linux

1. Install the vlan package using apt-get tool

· sudo apt-get install vlan

2. Load the Vlan (802.1q) module

· modprobe 8021q

· echo 8021q >> /etc/modules

3. Add vlan interface by using ‘vconfig add [interface-name] [vlan_id]‘ command syntax

· vconfig add eth0 188

· ifconfig eth0.188 192.168.188.100 netmask 255.255.255.0

· sudo gedit /etc/network/interfaces 

· auto eth0.188

· iface eth0.188 inet static

· address 192.168.188.100

· netmask 255.255.255.0

· vlan-raw-device eth0

 

 

4. Remove Vlan interface

· vconfig rem eth0.188
