Różne informacje o Linksys WRT54G.

Trochę chaotyczne informacje o routerze Linksys WRT45G i WRT54GS.

  1. Obejście TTL=1
  2. Overclocking CPU
  3. Ukryte Strony
  4. Wynik polecenia dmesg

1. Obejście TTL=1

nvram set rc_firewall='/usr/sbin/iptables -t mangle -A PREROUTING -j TTL –ttl-set 128'
nvram commit

2. Overclocking CPU
sprawdzenie czestotliwosci:

cat /proc/cpuinfo

ustawienie bezpiecznej większej częstotłiwości i zapisanie zmiany

nvram set clkfreq=216
nvram commit

3. Wynik polecenia dmesg
