Yaaa abilerim ablalarIm,
ftpd'nin listen edecegi portu degistirmek icin illaki gidip
services file'I icinden degistirmeniz gerekmez.
wu-ftpd'nin source'unu yeniden compile edersiniz olur biter.
yani source'un icine listen edecegi portu yazarsInIz.
ondan sonra compile edersinzi.
yani illaki in.inetd'nin handle edecegi bir service olmasI gerekmez.
standalone da calI$abilir.
yanii
