Po prvnim prihlaseni (telnetem) je treba si ined zmenit heslo (passwd), rebootnout AP a prihlasit se pres ssh (telnet se pak automaticky zablokuje).


  • Predelani linksyse na router co ma 5 sitovych ethernet karet (wifi zustava jedno)
    • Nastaveni 5ti sitovek na jednotlive porty switche (vcetne WAN)

<bash> nvram set vlan0_ports="1 5*" nvram set vlan0_hwname="et0" nvram set vlan1_ports="4 5*" nvram set vlan1_hwname="et0" nvram set vlan2_ports="2 5*" nvram set vlan2_hwname="et0" nvram set vlan3_ports="3 5*" nvram set vlan3_hwname="et0" nvram set vlan4_ports="0 5*" nvram set vlan4_hwname="et0" nvram commit reboot

  1. Nastaveni portu 1 pro vlan0 je vyzadovano pro budouci mozny upgrade firmware.
  2. Upgrade fw nejde kdyz neni port 1 ve vlan0.

</bash>

Pak bude toto rozdeleni
vlan0-> port3
vlan1-> wanport(internet)
vlan2-> port2
vlan3-> port1
vlan4-> port4
    • Aktivace zbyvajicich vlanu (defaultni jsou aktivni jen vlan0 a 1) je nutno provadet uz skriptem po kazdem bootu:

<bash> vconfig add eth0 2 #Pridat vlan2 k eth0 vconfig add eth0 3 #Pridat vlan3 k eth0 vconfig add eth0 4 #Pridat vlan4 k eth0

ifconfig vlan2 hw ether XX:XX:XX:XX:XX:02 #Nastavit mac adresu pro vlan2 ifconfig vlan3 hw ether XX:XX:XX:XX:XX:03 #Nastavit mac adresu pro vlan3 ifconfig vlan4 hw ether XX:XX:XX:XX:XX:04 #Nastavit mac adresu pro vlan4

ifconfig vlan0 xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx up #Nastavit IP adresu pro vlan0 ifconfig vlan1 xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx up #Nastavit IP adresu pro vlan1 ifconfig vlan2 xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx up #Nastavit IP adresu pro vlan2 ifconfig vlan3 xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx up #Nastavit IP adresu pro vlan3 ifconfig vlan4 xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx up #Nastavit IP adresu pro vlan4 </bash>

  • Nastaveni FD / HD / 10 / 100 pro jednotlive porty
    • Pro nastavovani jednotlivych vystupu, je treba nainstalovat balik robocfg
    • ipkg update
    • nasledovne na www kliknout na install u prislusneho baliku

<bash> robocfg show #Zobrazit aktualni konfiguraci vsech portu robocfg port X media <auto|10HD|10FD|100HD|100FD> #Nastaveni modu portu robocfg port X mdi-x <auto|on|off> #Nastaveni Auto-Cross </bash>

  • Nastavovani vystupniho vykonu radiove casti
    • Pro nastavovani vykonu je treba nainstalovat balik wl pres web admina linksyse
    • nastavovani vykonu probiha pomoci prikazu wl

<bash> wl curpower #Vypis vsech hodnot o vykonu wl txpwr X #X je v mW wl txpwr #bez parametru zobrazi aktualni nastaveni vykonu v mW </bash>

  • Ukazka jak umi wrt54gl regulovat:

Regulace-wrt54gl.PNG

  • Vetsi sloupec je wl txpwr 251 a ten mensi (zaregulovany) je wl txpwr 1
  • na obrazku z netstumbleru je videt ze to umi regulovat v rozmezi ca 25db
