桃機路線

[原則]

先走一高, 再走二高, 然後再走一高, 之後走五楊高架, 之後在桃園機場交流道下

[準備]

[說明]

走一高

休息站: 新營, 西螺

時速: 110 km/h

之後, 過彰化交流道之後, 靠右邊, 準備要走國道3號

到了彰化系統交流道, 切到國道3號

休息站: 清水, 西湖

時速: 110 km/h

之後, 到了新竹系統交流道, 再切到國道一號

休息站: 湖口

時速: 100 km/h

過湖口休息站之後, 靠右邊, 準備要走五楊高架橋,

五楊高架橋, 會有前後 2 段高架橋,

第一段高架橋, 從楊梅這邊上去, 是 2 線道, 一直走, 直到下高架橋, 一直保持靠右行駛 (不要切到左邊)

過不久, 就會來到第2段高架橋, 是 3 線道, 之後, 準備在機場系統下

下桃園機場交流道之後, 持續靠左邊行駛

之後, 會看到一排指標 "二航出境", "4號停車場", "二航入境",

重點是, 要停 "4號停車場", 所以不要走 "二航出境"

4號停車場有分 B1, B2
就照指標寫的, 直接去停 B2 (B1應該沒有空車位)

在 B2, 車停好之後, 往機場大廳的方向走, 會看到手扶梯, 手扶梯右邊玻璃門進去, 有美食廣場 (starbucks, 7-11, ...)

在美食廣場, 也可以直接搭手扶梯, 上去 2F 出境大廳

My OSX Experience

Here write down my experience about max osx.

How to disable Podcast automatic download.

Monday, December 22, 2014

bootup ubuntu-server-14.10 from pxe

step 1.
download netboot
wget -r --no-parent http://archive.ubuntu.com/ubuntu/dists/utopic/main/installer-i386/current/images/netboot/

step 2,
move netbook to /tftpboot/

step 3,
update /etc/dhcp/dhcpd.conf

subnet 192.168.32.0 netmask 255.255.255.0 {
range 192.168.32.2 192.168.32.254;
option routers 192.168.32.1;
option domain-name-servers 192.168.32.1;
filename "/netboot/pxelinux.0";
}

step 4.
power on the PC and choose boot from pxe option.

that's almost all.

bootup kali fro pxe

Bootup kali from pxe is almost like the way in bt5r3.

The difference lists below,

/tftpboot/pxelinux.cfg/default

TIMEOUT 100

DEFAULT kali

PROMPT 1

DISPLAY /isolinux.msg

LABEL kali

KERNEL kali/install/vmlinuz

APPEND initrd=kali/install/initrd.gz BOOT=install boot=install nopersistent rw quiet vga=0x317 netboot=nfs nfsroot=192.168.32.1:/tftpboot/kali

By the way, this time my experiment is working on vmware fusion to test this function, during the experiment, the vmware fusion is looking for ldlinux.c32 instead pxelinux.0, so my workaround is to copy a ldlinux.c32 to /tftpboot.

( In kali, ldlinux.c32 is in /usr/lib/syslinux/. )

Troubleshoot,
If the monitor compliant resolution out of range, try to change the vga option, for example vga=0x314.

28232 and 64511

28232 is a magic number.
it is different between 32768 and 61000.
32768 and 61000 is usually the definition of /proc/sys/net/ipv4/ip_local_port_range

so the whole story is that when i wrote a tcp client, i found that the maximum connection the tcp client created is always 28232, so i searched this number in google and found the reason.

The work around is
check the current definition first,
> cat /proc/sys/net/ipv4/ip_local_port_range

Change the definition
> echo "net.ipv4.ip_local_port_range = 1024 65535" >> /etc/sysctl.conf
> sysctl -p

After this setting, the maximum connection created by a tcp client will be 64511 - another magic number.
