 |
|
Ciao a tutti. ho letto in vari bios che esiste questa opzione di poweron on lan. Qualcuno sa come si attiva? Che tipo di icmp bisogna inviare o cos'altro bisogna inventarsi?

E' una voce del Bios delle moderne mainboard. Non ti so dire altro dal momento che non l'ho mai usata.

mai usato..però mi sembrava di aver letto che il semplice ping non funzionava..bisognava spedirne uno particolare...ma potrei sbagliarmi

non e' un ping normale. si tratta di un pacchetto particolare, chiamato magick packet forgiato in parte con il mac address della scheda di rete destinazione, e i campi restanti riempiti in FF.
qui sotto allego semplicissimo programmillo in c per svegliare un determinato mac address.
| Code: | /* ether-wake.c: Send a magic packet to wake up sleeping machines. */
static char version_msg[] =
"ether-wake.c: v1.09 11/12/2003 Donald Becker, http://www.scyld.com/";
static char brief_usage_msg[] =
"usage: ether-wake [-i <ifname>] [-p aa:bb:cc:dd[:ee:ff]] 00:11:22:33:44:55\n"
" Use '-u' to see the complete set of options.\n";
static char usage_msg[] =
"usage: ether-wake [-i <ifname>] [-p aa:bb:cc:dd[:ee:ff]] 00:11:22:33:44:55\n"
"\n"
" This program generates and transmits a Wake-On-LAN (WOL)\n"
" \"Magic Packet\", used for restarting machines that have been\n"
" soft-powered-down (ACPI D3-warm state).\n"
" It currently generates the standard AMD Magic Packet format, with\n"
" an optional password appended.\n"
"\n"
" The single required parameter is the Ethernet MAC (station) address\n"
" of the machine to wake or a host ID with known NSS 'ethers' entry.\n"
" The MAC address may be found with the 'arp' program while the target\n"
" machine is awake.\n"
"\n"
" Options:\n"
" -b Send wake-up packet to the broadcast address.\n"
" -D Increase the debug level.\n"
" -i ifname Use interface IFNAME instead of the default 'eth0'.\n"
" -p <pw> Append the four or six byte password PW to the packet.\n"
" A password is only required for a few adapter types.\n"
" The password may be specified in ethernet hex format\n"
" or dotted decimal (Internet address)\n"
" -p 00:22:44:66:88:aa\n"
" -p 192.168.1.1\n";

Notes:
On some systems dropping root capability allows the process to be
dumped, traced or debugged.
If someone traces this program, they get control of a raw socket.
Linux handles this safely, but beware when porting this program.
An alternative to needing 'root' is using a UDP broadcast socket, however
doing so only works with adapters configured for unicast+broadcast Rx
filter. That configuration consumes more power.

li ho provati entrambi ma ha funzionato solo 2 volte poi ha smesso il mac address nn + cambiato sono sicuro e nel bios la voce nn è cambiata.
(oltretutto non sono sicuro che le due volte che ha funzionato abbia funzionato a macchinatotalmente spenta ma in fase di spegnimento)
Tra parentesi ora sono a casa di un amico e nn posso accendere il pc ho provato sia lo script che il programma suggeritomi.
A questo punto mi viene un dubbio non è che si accende in lan solo se è in standby o cmq se nn è totalmente spento?

Cmq il MAC address non cambia mai! |

ne sono certo ho ricontrollato ora per scrupolo
cmq io spengo con halt forse devo spegnere con qlc altro parametro?
eppure il leddino sul frontale rimane acceso a bassissima luminosità segno che cmq la MB è accesa. Forse la scheda di rete va cablata con qualche roba strana?

Oltretutto il ping con lo script passatmi funziona quello col programma no

Cmq mi pare si debba collegare la scheda di rete in qualche modo alla scheda madre, solo che nn ho idea di come si faccia

# Script documentation
=head1 NAME
wakeonlan - Perl script to wake up computers
=head1 SYNOPSIS
wakeonlan [-h] [-v] [-i IP_address] [-p port] [-f file] [[hardware_address] ...]
=head1 DESCRIPTION
This script sends 'magic packets' to wake-on-lan enabled ethernet adapters and motherboards, in order to switch on the called PC. Be sure to connect the NIC with the motherboard if neccesary, and enable the WOL function in the BIOS.
The 'magic packet' consists of 6 times 0xFF followed by 16 times the hardware address of the NIC. This sequence can be encapsulated in any kind of packet. This script uses UDP packets.
=head1 OPTIONS
=over
=item -h
Displays the help information.
=item -v
Dislpays the script version.
=item -i ip_address
Destination IP address. Unless you have static ARP tables you should
use some kind of broadcast address (the broadcast address of the network where the computer resides or the limited broadcast address). Default: 255.255.255.255 (the limited broadcast address).
=item -p port
Destination port. Default: 9 (discard port).
=item -f file
File with hardware addresses of wakeable computers. For an example check
the file lab001.wol in the examples subdirectory.
=back
=head1 EXAMPLES
Using the limited broadcast address (255.255.255.255):
$ wakeonlan 01:02:03:04:05:06
$ wakeonlan 01:02:03:04:05:06 01:02:03:04:05:07
Using a subnet broadcast address:
$ wakeonlan -i 192.168.1.255 01:02:03:04:05:06
Using another destination port:
$ wakeonlan -i 192.168.1.255 -p 1234 01:02:03:04:05:06
Using a file as a source of hardware addresses and IP addresses:
$ wakeonlan -f examples/lab001.wol
$ wakeonlan -f examples/lab001.wol 01:02:03:04:05:06

E' quello che penso anche io... per caso a quelli a cui funziona il wakeonlan hanno la scheda di rete integrata nella mainboard?

Se il pc è spento e la scheda di rete pure come fa a leggere il ping e giudicare se è un pacchetto magico (nome orrendo) o no?
Deve essere in sleep!
(ora cosa si intenda con sleep non lo so! |

Bè alcune schede madri permettono al pc di autoaccendersi a una determinata ora.. anceh li devono essere in stadby?
Non ho mai provato ma credo che la batteria interna della scheda madre in qualche modo dia un minimo di elettricità per far eseguire al bios comandi come appunto quello dell'autoaccensione.. penso (e spero  ) che si possa fare la stessa cosa cn la scheda di rete

Non è la batteria, ma l'alimentatore stesso.
Le schede madri ATX in realta sono sempre alimentate, altrimenti come pensi possano accendersi con un semplice pulsante (e non un interruttore), o tramite tastiera.
Per le schede di rete integrate c'è una voce nel bios (o un jumper sulla cheda) che permette di attivare il wake on lan (mantenendo alimentata la scheda di rete anche a PC spento).
Per le schede di rete PCI, solitamente è presente un cavetto che va collegato su un connettore apposito sulla scheda madre, oltre alla solita voce nel bios (o jumper). |

| confermo che ci vuole il cavetto. (che danno sempre incluso nella confezione della scheda di rete) |
