Zakladni cil

  • Nainstalovat debian testing na Alix-APU s SSD diskem a pripravit navod pro ostatni
  • Diky tomu ze hardware nove APU desky je pomerne vykony, neni problem na nem rozbehnout prome klasickeho routovani(ospf) i dalsi sluzby(DNS, mail, jednoduchy web, statistiky prenosu...)
  • Procesor je x86(konkretne architektura amd64), 2xcore 1GHz
  • Jde pripojit SSD disk pres mSATA, nebo klasicky disk pres SATA - idealni na klasickou instalaci linuxu(zadne omezeni readonly CF).
  • Klasicky disk pres SATA se nevejde do krabicky, tak jsem zvolil mSATA od pcengines s kapacitou 16GB
  • V pripade potreby neni problem koupit vetsi mSATA napr. u alza.cz - az 500GB
  • Cely navod je hodne detailni, experti se snad neurazi :-). Pro zkusenejsi: Jedina vetsi slozitost spociva v nastaveni bootloaderu a kernelelu tak aby produkoval vystup na RS323. Ostatni je standardni instalace linuxu(debianu).

Instalace HW

  • Nalepit chladic(kus plechu) podle navodu vyrobce, hlinikova krabicka pomaha taky chladit
  • Zastrcit SSD disk
  • soupnout do krabicky

Pripojeni pres seriovou linku

  • APU nema grafickou kartu, takze je potreba pripojit se seriovou linkou.
  • Pro ty mene stastnejsi z nas kteri uz nemaji v notebooku seriovy port je potreba neco jako: USB->RS232 a null-modem cable null-modem kabel
  • Nastaveni rychlosti serioveho portu 115200 8N1
  • Nalezeni spravneho cisla COM portu prirazeneho prevodniku. viz screenshot

Com number.png

  • Pres putty viz screenshot
  • Pres hyperterminal viz. screenshot

Pripraveni instalacniho USB

Nastroj na pripraveni instalacniho USB

Rucni pripraveni instalacniho USB v Linuxu

  • Vychazel jsem z navodu | 4.3.3. Manually copying files to the USB stick — the flexible way
  • Staci jakakoliv USB flashka s velikosti >>1GB
  • Predpokladam ze flashka je naformatovana na fat16 a oznacena flagem bootable. V pripade ze tomu tak neni, libovolnym nastrojem nastavime(cfdisk, fdisk,...)
  • Pro kontrolu overime(v mem pripade 4GB USB flashka)
 NPSWorkstation1:~# fdisk -l /dev/sdh
 Disk /dev/sdh: 4110 MB, 4110188544 bytes
 67 heads, 14 sectors/track, 8558 cylinders, total 8027712 sectors
 Units = sectors of 1 * 512 = 512 bytes
 Sector size (logical/physical): 512 bytes / 512 bytes
 I/O size (minimum/optimal): 512 bytes / 512 bytes
 Disk identifier: 0x00000000

 /dev/sdh1   *          62     8027711     4013825    6  FAT16
  • Nainstalujeme bootloader. Debian pouziva pro instalacni USB syslinux(jinak by sel pouzit i grub nebo lilo). Flashka nesmi byt primountovana.
 NPSWorkstation1:~# syslinux /dev/sdh1
  • Primountujeme USB flashku
  mount /dev/sdh1 /mnt/temp
  • Stahneme z hd-media soubory vmlinuz a initrd.gz
  • Stahneme z cdimage soubor debian-testing-i386-CD-1.iso
  • Vsechny 3 soubory nakopirujeme na USB flasku
  • Vytvorime na USB flashce soubor syslinux.cfg s nasledujicim obsahem:
 NPSWorkstation1:/mnt/temp# cat syslinux.cfg
 serial 0 115200
 default vmlinuz
 append initrd=initrd.gz console=tty0 console=ttyS0,115200n8

=== Rucni pripraveni instalacniho USB v prostredi Windows

Vlastni instalace Debianu

  • TODO... Klasicka instalace

Tipy

  • zkontrolovat FD/HD pres mii-tool a ethtool

Performance testing

  • vsechny testy bez NATu, ipv4
  • test pres iptraf TCP halfduplex v podstate cely 1Gbit/s
  • test pres iptraf TCP fullduplex zvladne tak kolem 500Mbit/s, cca 20 000pps. Pravdepodobne uz nestihaji irq/s --> Mozny tunning pres irqbalance a podobne??

Pripojit mobilku s androidem jako zdroj internetu

  • Na androidu Nastaveni --> Sdileni pripojeni --> enable sdileni pripojeni pres USB
  • Na APU
