Zdravím.
neviete niekto ako sa da spravit pomocou PHP scriptu zistovanie IP na sieti? Teda kolko IP je pouzitych na sieti alebo lepsie povedane koľko PC je on-line. Predstavujem si to takto. Spustim script a on mi na vystupe zobrazi pocet IP. Nemusi byt cely script, ale iba ta cast ako zistim pouzitu IP. dik. |

myslim ze ked miesto ping pusti nmap na zadany rozsah, povie mu to asi viacej, v kazdom pripade plati jmi-ho poznamka o tom, ze dobre zabezpecene php ti taketo veci nedovoli  |

Default execution time nastaveny v php je 30 sec... (da sa samozrejme zmenit) Ak to dovtedy nmap nestihne, tak vo vysledku toho asi moc nebude... radsej len hardcore ping...  |

| sunnyday: max_execution_time hovori o tom, kolko casu moze stravit proces na procesore a nie o tom ze za kolko sekund musi najneskor skapat |

| si: samozrejme, ze sa rata len cisty cas bezania procesu, ja len, ze scanujem vacsi rozsah IP adries tak to trva niekedy znacne dlhsie... |
