How To Backup Local Unix Host Using rsnapshot rsync Utility

How To Backup Remote Linux Host Using rsnapshot rsync Utility

server 端

設定 /etc/rsyncd.conf, 一組設定稱為一個module
[KG6500_Stream]
path = /media/HD-CEU2 # server 端的備份位置
uid = root
gid = root
secrets file = /etc/rsyncd.secrets # 帳號密碼設定檔
read only = no

client

要備份的資料夾: /home/Stream
執行 rsync -vrtopg --progress --password-file=/etc/rsyncd.secrets /home/Stream backup@127.0.0.1::KG6500_Stream
會將client端的/home/Stream 整個資料夾備份到/media/HD-CEU2/Stream

參數說明

v : 顯示進度
r : 遞迴
topg : 維持檔案屬性

# /etc/init.d/networking stop

首先要知道網路卡的driver module name

# lsmod (找出網路卡module : NICmod)

# rmmod NICmod

確認udev rule for NIC設定檔

通常在 /etc/udev/rules.d/xxx-net.rules

將它清空，重新載入NIC module

# modprobe NICmod

# /etc/init.d/networking start

將a.txt裡面的xxx取代成yyy，存到b.txt

sed 's/xxx/yyy/g' a.txt > b.txt

取代行首

sed 's/^/yyy/g' a.txt > b.txt

取代行末

sed 's/$/yyy/g' a.txt > b.txt

Journaling Flash Filesystem 是 Log 類型

通常是因為開啟了Domain Name 反查

修改 /etc/ssh/sshd_config

加入一行 UseDNS no

另一個方法：

把client 端的 ip & hostname 加到 ssh server 那台電腦裡的 /etc/hosts

用臺灣高品質學術研究網路的Repositories

http://ftp.twaren.net/Linux/Ubuntu/ubuntu/

因為一個疏忽，出了一個大漏洞，導致ssh key 容易被暴力破解

真不敢相信debian 這麼嚴謹的distro 會出這種錯誤

而且擺了一兩年

他媽的USB似乎根本就沒啟動

帥哥的測試：

GPH10 控制小 port：0 是打開 1 是關掉
GPH8 控制大 port： 1 是打開 0 是關掉

送電之後就可以用了...他媽的白費兩個禮拜

之前請正哥寄信去要電路圖都不屌我們

COLOR 打電話去就要到了

更正

GPH8 : USB_HOST_EN

GPH10 : nUSB_PULL_UP_EN

USB_HOST_EN 控制 USB_H_5V --> USB HOST PORT 的供電 (大PORT)

nUSB_PULL_UP_EN 控制 USB_C_D+ --> MINI USB 的供電 (小PORT)

rt73的debugfs出來的資訊就在ieee80211裡面

UPDATE : 學弟搞定了
usb host timeout的原因是....usb controller過熱被保護電路關電.......

林老師卡好勒

=============================================================
great~ it offers linux driver~

copy the directory Linux/rt73 in the Driver CDROM ( remember to chmod +w )

follow the README in Linux/rt73/module/

if you got error "undefined get_wireless_stats"

just fix rtmp_main.c, replace netdev->get_wireless_stats to netdev->get_stats

=======================================

編譯module

網路上有非官方driver : rt2x00 project

每天最新版本

或是直接用CVS更新

cvs -d:pserver:anonymous@rt2400.cvs.sourceforge.net:/cvsroot/rt2400 login

cvs -z3 -d:pserver:anonymous@rt2400.cvs.sourceforge.net:/cvsroot/rt2400 co -P source/rt73

修改Makefile

最前面增加五行

ARCH=arm

CROSS_COMPILE=/usr/local/arm/3.4.1/bin/arm-linux-

KERNDIR=/home2/fyodor/kernel/linux-2.6.25__from__2.6.24.3

(KERNDIR要指到目標板所使用的KERNEL SOURCE，而且KERNEL必須先設定好交叉編譯)

ROOTFS = /home2/fyodor/filesystem/rootfs

MODDIR = /lib/modules/2.6.24.3/extra

把module install 的目標位置依照目標kernel版本設定

否則就會安裝到目前uname -r 所找到的kernel module位置...

ps. make install時，modules.dep的設定不會跟著MODDIR而改變

所以還是得設定成extra

修改一行

FIRM_DIR := $(ROOTFS)/lib/firmware

編譯

(host)# make armdebug

警告訊息

!!! WARNING: Module file much too big (>1MB)
!!! Check your kernel settings or use 'strip'
*** Module rt73.ko built successfully

表示編出來的module太大了，這個好解決

必須削減(strip)多餘訊息（strip之後，板子上無法modprobe！format不合）

(host)# arm-linux-strip ./rt73.ko

把module安裝到target rootfs

這一步，我不很確定怎麼做，試看看吧～

(host)# sudo make install

*** Install module in /lib/modules/2.6.24.3/extra ...
make[1]: Entering directory `/home2/fyodor/kernel/linux-2.6.25__from__2.6.24.3'

警告訊息

WARNING: Couldn't find symtab and strtab in module /lib/modules/2.6.20-15-generic/extra/rt73.ko
*** Update /etc/modprobe.d/ralink alias for wlan*
*** Install firmware in /home2/fyodor/filesystem/rootfs/lib/firmware ...
*** Check old config ...

因為這一個編譯所使用的kernel版本2.6.24.3，和host機器上目前使用的版本2.6.15不同導致這個錯誤不知道怎麼處理... 應該是沒關係因為真正運作時，這個module在板子上所配合的kernel 版本就對上了參考： http://www.linuxsir.org/bbs/thread307321.html

結束

一樣照著路徑複製到rootfs裡面

module : /lib/modules/2.6.24.3/extra/rt73.ko

firmware : /lib/firmware/rt73.bin

status code :

s3c2410-ohci s3c2410-ohci: urb c2704ec0 path 1 ep0in 5ec20000 cc 5
–> status -62

all status code : include/asm-generic/errno.h

#define ETIME 62 /* Timer expired */

Document of error codes : Documentation/usb/error-codes.txt

-ETIME (**)

No response packet received within the prescribed bus turn-around time. This error may instead be reported as -EPROTO or -EILSEQ.

懶惰的script

為什麼會timeout勒..... 搞了一個禮拜還是搞不清楚

rt73: USBVendorRequest TIMEOUT是我自己加的訊息

總之status -62 = -ETIME，就是TIMEOUT

上面說過了，status code的詳細定義在$(KERNDIR)/include/asm-generic/errno.h

error的解釋在$(KERNDIR)/Documentation/usb/error-codes.txt

去rt2x00.serialmonkey.com post問題，一邊trace driver 一邊等

覺得問題比較有可能出在s3c2410-ohci

畢竟這部份的2440移植，我做的很粗糙

交叉編譯rt73usb driver的時候，需要指定kernel source路徑

# cd RT73_Linux_STA_Drv1.0.4.0/Module

# make ARCH=arm CROSS_COMPILE=arm-linux-

\KERNDIR=/home2/fyodor/kernel/linux-2.6.25__from__2.6.24.3/

出現了這個警告

warning: `regparm' attribute directive ignored

網路上查到是說

kernel src directory裡面的 include/asm

他是一個link，應該要指向corss compile目標

(在我這個情況就是asm-arm)

如果沒把asm 指到 asm-arm，就會出現這個warning

http://osdir.com/ml/linux.gps/2006-02/msg00049.html

http://linux.chinaunix.net/bbs/archiver/?tid-916672.html

可是我有正確指過去啊....怎麼還是出現這個warning
