OpenWRT firmware Whiterussian RC5 do Linksyse WRT54GL najdete zde
- Nahrava se pomoci WWW rozhrani primo v linksysu.
- Prihlaseni do original firmware je bez jmena a heslo je admin
- Defaultni IP je 192.168.1.1 (maska 255.255.255.0)
- Po prvnim prihlaseni (telnetem) je treba dat reboot, aby se zaktivoval filesystem
- Po prvnim rebootu si ihned zmente heslo (passwd), rebootnout AP a prihlasit se pres ssh (telnet se pak automaticky zablokuje).
- Toto heslo je zaroven heslem na www (uzivatel root)
- robocfg a wl (+jine utility) je treba dohrat jako balik pres zalozku system - installed software. Jako prvni je treba dat "Update package lists"
- 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
- Nastaveni portu 1 pro vlan0 je vyzadovano pro budouci mozny upgrade firmware.
- 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:
- 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
- Drobne stripky z testovani HWAP Linksys:

== Jak ozivit napul mrtvý WRT54GL ==
Kdyz uz je Linksys po zaruce a umrel nam treba po flashovani tak je treba k jeho oziveni ho kuchnout. Pozor pokud je jeste v zaruce, tak timto kuchnutim tu zaruku ztratis.
- Sundej gumove nozicky a vem plochy sroubovak. Nyni je treba ho zarazit do nozicky. Az to hlasite krupne (ne okolni plast, trosku s citem), tak je pripraveno k rozdelani. Toto u vsech 4 noh. Az se ti ho podari rozlousknout, tak pokracuj v nasledujicim bodu.
- Pokracujem tedy dal. Pin 16 u flash pameti vyzkratovat na zem, zapnout AP do elektriky. Nyni se vse rozsviti jako vanocni stromek. Cekej nez to vse pohasne. Nyni je Linksys ve flashovacim rezimu a ma ip 192.168.1.1 Pokud ne, tak je bud uplne spatnej, nebo si neco vynechal => zkus to vse znovu. Nyni pomoci tftp nahraj firmware:
<bash>
- tftp 192.168.1.1
> binary > trace > rexmt 1 > timeout 90 > put firmware.bin </bash>
- Ted bude blikat dioda POWER, Nesahat dokud neprestane blikat. Dle posledniho ozivovani to trvalo cca 10min. Az zhasne, tak mame flashnuto. Pokud ted nenapingas Linksys, tak je treba mu jeste smazat NVRAM.
- Smazani NVRAM: Vypni Linksyse,stiskni a drz tlacitko reset, zapni Linksys do elektriky. Dokud se nerozsviti DMZ drz reset, pak pust. Ted je NVRAM vycistena. Po zhasnuti DMZ by ses mel uz dostat telnetem na Linksys (192.168.1.1)
