[dd] Anoshandisa muGNU / Linux masisitimu

3 maminitsi

Sezvo isu tese tichiziva, vadikani dd [dd raira pane GNU / Linux masisitimu] mukomana mukuru kana zvasvika pakuita isos, kuchengetedza / kunyora MBR pakati pemamwe mabasa. Asi ikozvino zvakanaka ndinoita sei iyo ISO nayo?

Zviri nyore kwazvo, chingomhanya zvinotevera mune yako terminal:

dd if=/dev/cdrom of=/home/Install/Isos/debian-7.0.0-i386-CD-1.iso

if, kubva ku "yekuisa faira", Y of kubva ku "kuburitsa faira", Izvo zviri pachena kuverenga mumurume zvinotora rimwe jusi kune orenji xD. At if yekuisa mudziyo inotsanangurwa, uye mune iyo of iyo nzira yekubuda yeiyo ISO faira ichave yakatsanangurwa. Chinyorwa chakakoshane katsi zvinokwanisika kuita zvakafanana, izvo katsi haina kutakura if ni of.

cat /dev/cdrom /home/Install/Isos/debian-7.0.0-i386-CD-1.iso

Saka, tatoziva izvi, ngatiende kumberi. Kumwe kushandiswa ndekwekuti sodomize USB [Sodizeize?], Hongu, ndinoziva zvinoita kunge zvakashata, asi hei, kune avo vanotenga USB memory stick uye vanorwadziwa kuti vaba, ndiko kuti, kutengesa USB tsvimbo 4GB uye iri 128MB, iyo zvinogumbura, tinogona kuita bvunzo yepamoyo:

Kunyora bvunzo:
dd if=/dev/zero of=/dev/sdb1 bs=1M count=4096

Kuverenga bvunzo:
dd if=/dev/sdb1 of=/dev/null bs=1M count=4096

Kuteedzera / kuverenga 4GB yemazero kuUSB, kutarisa kuti iri 4GB here. Kana ikapera kare uye ikasaisa huwandu hwakatarwa, iwe wakabiridzirwa xD

Ongorora: tarisa mushe inova iyo USB chishandiso iwe chawakabatana, nekuti unogona kukoka kutamba kune yako HDD [SATA] uye kurasikirwa neyese info iwe yauinayo !!!

Zvimwe zvinoshandiswa zvakasiyana ...

Clone rakaoma dhiraivha, kune IDE anotyaira:
dd if=/dev/hda of=/dev/hdb bs=1M

yezvifambiso zveSATA:
dd if=/dev/sda of=/dev/sdb bs=1M

Kopa iyo Master Boot Record:
dd if=/dev/hda of=mbr count=1 bs=512

Kudzorera iyo MBR:
dd if=mbr of=/dev/hda

Gadzira 1GB swap faira:
dd if=/dev/zero of=/boot/swap_space bs=1M count=1024
mkswap /boot/swap_space
swapon /boot/swap_space

[Uye zvevabiridzi xD, #ZOMG, hackers]

Mazuva mashoma apfuura ndanga ndichiverenga nzira dzekumisikidza HDD yedu, ndisingasiye kana tara pairi chero chinhu chaimbove chiripo, ndisingatombo shandisa chishandiso chepamusoro chakavanzika chekudzosa ruzivo, uye nekunyongana / kugutsikana kwangu dd yaive imwe yesarudzo dzinogona kuitika.

Asi ndingaite sei izvi? Nyore:

dd if=/dev/zero of=/dev/sda bs=1M

Kuzadza dhirairi rakaoma nemazero. With bs = 1M, tiri kuti kuverenga nekunyora zvese kunoitwa mumablock 1 megabyte. Tinogona zvakare kushandisa / dev / random, asi zvinotora nyika, ichiiwana yekupedzisira muyedzo yekukurumidza kudzima: D.

Saka FBI haizowane chero chinhu pane yako HDD xD ...

Chinhu chekuziva ndechekuti iro revo yekutanga yeanotangisa dd zvirinani kuti zvakadzimwa nekufamba kwenguva, saka inogona kudaidzwa nenzira dzakawanda: duplicate mudziyo, diski duplicator, dhata dump, diski muparadzi, nezvimwe.

Iko kushanda kwe dd ndiko kuchenesa tafura yekuparadzanisa. Izvi zvinogona kubatsira kugadzira yakachena partition scheme pane yakashandiswa dhisiki, pasina kudzima diski rese. Semuenzaniso, kana iyo system ikaona diski se / dev / sdb Tinogona kunyora yekutanga 256MB kusvika zero (chaizvo tafura yekuparadzanisa iri mumakumi mashanu nemakumi mashanu nemaviri emabheti, asi sezvo zvikamu zvekutanga zve diski zvinowanzo kuve zvakakosha, kuitira chengetedzo huru ndinochenesa nzvimbo yakawanda)

dd if=/dev/zero of=/dev/sdb bs=512 count=512K

Uye zvakare, dzimwe nguva kunyora flash memory ine zeros kunogona kubatsira kuitora, iyo nzira yakafanana inogona kushandiswa.

Kumwe kushandiswa kunonakidza kutora ruzivo nezveBIOS pasina kutanga, izvo zvinogoneka nekuti muLinux dzinenge zvese zviwanikwa zvinogadziriswa semafaira, kusanganisira RAM (ruzivo rweBIOS rwakachengetwa mune yekupedzisira 32KB yekutanga MB memory).

dd if=/dev/mem bs=32k skip=31 count=1 | strings -n 8 | grep -i bios

Izvo zvinoita uyu murairo zvinotsanangudza saizi yebhokisi mumakumi matatu nemaviri emakirobytes uye ndokusvetuka ekutanga makumi matatu nematatu (ndokuti, skip 32 kilobytes), sefa sefa kuti uratidze tambo chete dzevasere kana anopfuura mavara, uye tsvaga mune izvo tambo dzeiyo iyo ine izwi rekuti BIOS.

Dd haina kana kutarisa. Chii chinoitika kana iwe uine imwe yemusango yakaoma dhiraidhi chiitiko, uye iwe usingawani iwo ese mabiti akateedzerwa? Iwe une yakaipa ISO, uye hauzombozviziva.

Pane kudaro, iwe unofanirwa kunge uchishandisa chishandiso chakakodzera chebasa chairo. Mune ino kesi, iwe unofanirwa kutarisa iwo 'kuverenga' kuraira (verenga optical media). Inoita chaizvo zvauri kutsvaga, uye yakavaka mukukanganisa kutarisa.

kuverenga dev = / dev / scd0 f = / imba / shamanstears / test.iso

Kana iwe uchida kunyora iyo ISO, saka unofanirwa kunge uchishandisa 'wodim', kwete 'dd', kana chero imwe inotyisa «mhinduro».

wodim -v -eject / imba / shamanstears/test.iso

Izvi zvinopisa yako 'test.iso' kuCD yako isina chinhu, uchifunga kuti yatopinzwa, uye kurasa kana yapera. Chichatove chiito nezve izvo zvabuda munzira. Aya matipi akashata uye matipi ndiwo anoita kuti vashandisi vazhinji vave mumatambudziko. Rangarira- shandisa maturusi akakodzera ebasa chairo, uye munhu wese achafara.
