Spustas to ako user apache a do logov zrejme nema pravo zapisu.

Niekdajsie verize apacha mali moznost nastavit rezim prevadzky,
kde sa zadavalo "standalone" alebo este nieco ine. Toto nastavenie
urcovalo, ci bude bezat apache cez inetd alebo samotne.
Terajsie verzie to uz ale asi nemaju, takze ho asi nebudes moct spustat
cez inetd.

Ta chyba znamena, ze apacha sa ti snazil pripojit na port 80,
ale na nom ti uz bezi xinetd. Je to normalna hlaska, pokial nedas
vediet apachu, ze chces aby bezal cez xinetd. Podobne je to aj
s ostatnymi aplikaciami. Musis im dat vediet, ako maju bezat.

Aplikacie beziace cez xinetd sa nepripajaju na tcp alebo udp port,
ale komunikuju cez standardny vstup a vystup. xinetd takto ziskane
informacie posiela na dany port.
