Hi sir,
i want to make such programe which takes MAC(Ethernet) address of any host & give me its IP address.......
but i'm nt getting that how i can pass the MAC address to Frame........
Please give me an idea for making such program...
Thanks & regards

Hi,
I've got a Sun Solaris machine with host ID (840f8e57) and MAC address (0:14:4f:f:8e:57), how do I:
1. Write the MAC address in standard (IEEE 802) format, i.e. xx-xx-xx-xx-xx-xx? Do I need to add 0's before or after the 'f', i.e. 00-14-4f-0f-8e-57 or 00-14-4f-f0-8e-57?
2. What is... (4 Replies)
I have following message in my messages file on solaris 10
WARNING: e1000g3712000:3 has duplicate address 010.022.196.011 (in use by 00:50:56:85:25:ef); disabled
Now is there any way i can find which server has 00:50:56:85:25:ef mac address either IP or Hostname ? (6 Replies)

I lost connectivity to one of our remote systems and when I checked the messages log I found the following:

Hi,
mac.txt
My mac address is <Mac Address>.
How can i replace <Mac Address> with the actual of my computer?
I try to GREP command as below but i am unable to grep it to replace just <Mac Address>.
ifconfig eth0 | grep -o -E '(]{1,2}:){5}]{1,2}'
Million in Advance.

four interfaces with ifconfig
all interfaces have the same mac. If is not set for unique.
but it still works.
what difference does it make to have all macs the same or different? (4 Replies)

te(7) Miscellaneous Information Manual te(7)NAME
te - TGEC Ethernet interface
SYNOPSIS
config_driver te
DESCRIPTION
The te interface provides access to a 10 Mb/s Ethernet network through the TGEC controller.
The host's Internet address is specified at boot time with an SIOCSIFADDR ioctl. The te interface employs the address resolution protocol
described in arp(7) to map dynamically between Internet and Ethernet addresses on the local network.
The SIOCSPHYSADDR ioctl can be used to change the physical address of the TGEC. The SIOCRPHYSADDR ioctl can be used to read the physical
address of the TGEC.
The SIOCADDMULTI and SIOCDELMULTI ioctls can be used to add or delete multicast addresses. The TGEC recognizes a maximum of 12 multicast
addresses.
The SIOCRDCTRS and SIOCRDZCTRS ioctls can be used to read or ``read and clear'' the Ethernet driver counters. The argument to these two
ioctls is a pointer to a counter structure, ctrreq, found in <net/if.h>.
The SIOCENABLBACK and SIOCDISABLBACK ioctls can be used to enable and disable the interface loopback mode respectively.
EXAMPLES
To obtain the physical address of the adapter, use the SIOCRPHYSADDR ioctl as in the following program example: #include <stdio.h>
/* standard I/O */ #include <errno.h> /* error numbers */ #include <sys/socket.h> /* socket definitions */ #include
<sys/ioctl.h> /* ioctls */ #include <net/if.h> /* generic interface structures */
main() {
int s,i;
struct ifdevea devea;
/* Get a socket */
s = socket(AF_INET,SOCK_DGRAM,0);
if (s < 0) {
perror("socket");
exit(1);
}
strcpy(devea.ifr_name,"te0");
if (ioctl(s,SIOCRPHYSADDR,&devea) < 0) {
perror(&devea.ifr_name[0]);
exit(1);
}
printf("Address is ");
for (i = 0; i < 6; i++)
printf("%X ", devea.default_pa[i] & 0xff);
printf("
");
close(s); }
To enable external loopback, use the SIOCENABLEBACK ioctl as in the following program example: #include <stdio.h> /* standard
I/O */ #include <errno.h> /* error numbers */ #include <sys/socket.h> /* socket definitions */ #include <sys/ioctl.h>
/* ioctls */ #include <net/if.h> /* generic interface structures */
main() {
int s;
struct ifreq data;
/* Get a socket */
s = socket(AF_INET,SOCK_DGRAM,0);
if (s < 0) {
perror("socket");
exit(1);
}
strcpy(data.ifr,"te0");
if (ioctl(s,SIOCENABLEBACK,&data) < 0) {
perror("SIOCENABLEBACK:");
exit(1);
}
close(s); }
ERRORS
The diagnostic error messages contain relevant information provided by the TGEC. The interface was handed a message with addresses format-
ted in an unsuitable address family, and the packet was dropped. The TGEC hardware failed to reset itself properly. The driver's attempt
to allocate a buffer failed. The driver's attempt to allocate a buffer failed. Too many multicast requests have been made. The shared
memory block for the TGEC's local RAM buffer is missing from the CMOS configuration data.
