Salut !!!

La cosa tenía que ser molt senzilla, agafar els discs nous, crear 3 particions primàries i una extesa amb unes quantes particions més, anteriorment ho havia fet a un Dell E6400 sense problemes (no tenia cap partició amb windows 2000).

Al fer-ho als Dell D620 amb dues particions de windows 2000, al arrancar hem sortia pantalla blava amb un error STOP 0x0000007B “INACCESSIBLE_BOOT_DEVICE” i no hi habia maneres d’arrencar cap de les particions amb windows 2000, en canvi Xp i Ubuntu, arrancaben sense problemes…

Després de fer moltíssimes proves, vaig donar amb el problema. El windows 2000 no reconeix discs més grans de 128 Gb, perque ho faci, cal modificar el registre el seguent paràmetre BigLba de la seguent manera:

• Anar a Inici – Ejecutar
• Escriure Regedit i pitjar return
• Navegar per el registre fins anar a: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters.
• Fer click a la clau “EnableBigLba” i modificar el valor per defecte a “1″ en cas de no existir aquesta clau, la podem crear manualment com registre DWORD i posar per defecte el valor a “1″
• Reiniciem equip

Salut !!!

Hi ha el software que es diu Airvision i el Airvision-nvr, aquest ultim transforma el pc amb un gravador. Per instal·lar-ho es senzill gràcies als repositoris d’ubiquiti.

Afegim el repositori:

nano /etc/apt/sources.list

deb http://www.ubnt.com/downloads/airvision/apt natty ubiquiti

Ens baixem la key

wget -O – http://www.ubnt.com/downloads/airvision/apt/airvision.gpg.key | sudo apt-key add -

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install airvision  (soft cams)

sudo apt-get install airvision-nvr (soft grabacio)

Ja hi podem accedir amb la ip del server:7443

Salut   !!!!

apt-get update
aptitude update
aptitude install java6-runtime-headless
aptitude install jsvc
cd /tmp
descarreguem el software: wget (wget http://www.ubnt.com/downloads/aircon…3-beta_all.deb) l’adressa fiquem l’actual, es pot mirar al seguent post per quina versió van http://forum.ubnt.com/showpost.php?p=177840&postcount=1
instalem amb dpkg (dpkg -i aircontrol_1.3.3-beta_all.deb)

Ja el tenim muntat i a punt per fer-lo anar amb la ip del server:9080

Si us dona error al iniciar Java, cal editar el seguent…

nano “/etc/init.d/aircontrol”
Canvia la linea “JAVA HOME=” per el seguent “JAVA_HOME=/usr/lib/jvm/java-6-openjdk/jre”
/etc/init.d/aircontrol start

Salut !

He començat l’any jugant amb màquines virtuals i en tenia alguna amb el VirtualBox i m’interessa passar-la al meu nou server amb VMWare, aquí tenius les passes que he seguit:

Anem a convertir una imatge de Vmware a VirtualBox

$qemu-img convert SistemaOperativo.vmdk /tmp/SistemaOperativo.bin

Ara fem servir VirtualBox Manage per convertir la imatge de .bin a .vdi

$VBoxManage convertdd /tmp/debian.bin debian.vdi

Si volguessim fer-ho al revés o sigui convertir de Virtualbox a Vmware primer convertim l’arxiu de .vdi a .raw

$vboxmanage internalcommands converttoraw debian.vdi debian.raw

I després fem servir Qemu per passar a .vmdk

$qemu-img convert -O vmdk debian.raw debian.vmdk

Salut !! i recordeu que si us falta algún paquet, cal fer un apt-get install xxxx

Salut !!!

Salut !!
