How to change host id for RedHat 7.3 ?

[mike]

Hi,
I want to install some EDA tools to several pcs.
Every Pc shows different host id.
It is difficult for me to maintain lic for each PC.
Is there any method to change host id for Redhat 7.3 ?

Sincerely,

linux change hostid


Sorry,
What I need is to change HOSTID not HOSTNAME .

change hostid

What do you mean HOSTID ? Is that serial number of your HD ? MAC Adress ? EDA programs define HOSTID differently.

Hello Mike ,

If your HOSTID is the MAC ADDRESS of your ethernet card you may give
a look at this topic
h**p://www.elektroda.pl/eboard/viewtopic.php?t=25188
*->t
else , you can try to generate license files (with E*F*A*L*i*c*g*e*n)
with HOSTID=ANY .

Good luck

changing the hostid on linux pc is very ease, and this change is permanent, you can use only one line program to resolve it. but now I forget the source file. I will give it to you after a moment.

redhat hostid ändern

#include <stdio.h>
#include <ctype.h>
#include <unistd.h>

int main(int argc, char *argv[])
{
int i;
unsigned long id;
char *str;

printf("Hostid tool for Linux/x86 platform\n");
if (argc < 2) { Thu Aug 1 12:43:36
CST 2002
id = gethostid();
printf("Hostid is: %X\n", id);
exit(0);
}

str = argv[1];
id = 0l;
i = 0;
while (str && i < 8) {
if (isdigit(str)) id = (id << 4) + str - '0';
else if (isxdigit(str))
id = (id << 4) + toupper(str) + 10 - 'A';
else break;
++i;
}

if ( i == 8) {
sethostid(id);
printf("Hostid changed to: %X\n", id);
} else printf("Error : incorrect hostid (%s)\n", str);

}

i think that the graphical tool is much much better...ie network device management

You may get your HOSTNAME from /etc/hostname.

change host id

To change the host ID, try to type the following statements in bash:

ifconfig eth0 down
ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx
ifconfig eth0 up

The above statements are only valid if u interface is eth0=Ethernet0

changer hostid linux redhat

Hi all, I've used the script above, but I have to replicate an hostid of another machine that starts with a 0; and when I try to modify the value my hostid was set without the first 0. I've tried all in my possibilities and I've googled a lot but without benefits.

value to replicate: 0f38c25b
value set by the procedure: f38c25b



Someone tell me how to solve this problem??:roll:
My OS is a RedHat Linux.
thanks thanks thanks thanks thanks thanks
