hi all,
i tried to write a packet (for fun) in ARP format
(which i build) to the network - i wrote this code below with help
looking at the man pages for "packet". I could read ARP packets but
when i tried to write one - the code fails - i get an error message
printed by perror which says
" Write failed :No such device or address"
Could somebody point out what i have missed out . The arp.h header
file is mine and have pasted its contents below.
Thank you.

A correction : i had sent the code as follows - the array index seem
to be not proper - i had changed it to 0,1,2...5 later on... Sorry
for the error.
before:
pkt->ether.source_addr[0] = 0x00;
pkt->ether.source_addr[1] = 0x50;
pkt->ether.source_addr[0] = 0xBA; /* my MAC Address */
pkt->ether.source_addr[0] = 0x88;
pkt->ether.source_addr[0] = 0x15;
pkt->ether.source_addr[0] = 0xF9;
Now:
pkt->ether.source_addr[0] = 0x00;
pkt->ether.source_addr[1] = 0x50;
pkt->ether.source_addr[2] = 0xBA; /* my MAC Address */
pkt->ether.source_addr[3] = 0x88;
pkt->ether.source_addr[4] = 0x15;
pkt->ether.source_addr[5] = 0xF9;
even after the changes - the code doesn't work - it gives me the
same error - someone please let me know what's wrong with the code .
thank you.
