1. I do not use SuSe Linux, but with this program, you could set the hostid on any machine, and at least on all linuxes.

   Save this as hostid.c and compile it using

   # gcc hostid.c
   ( Needless to say, you need to be a superuser)

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

   int main(int argc, char *argv[])
   {
   if(argc < 2)
   {
   fprintf(stderr,"Usage:%s <hostid>\n",argv[0]);
   return 1;
   }
   sethostid(
   strtoul(argv[1],NULL,16) );
   return 0;
   }

   The first argument you supply is the hexadecimal hostid you want to set ( You can pass the output of hostid command here, if you want to set your hostid to a particular host). Then verify that the set is successfull by issuing hostid again.

   You may be interested in knowing that hostid is stored in /etc/hostid (not as text though, or you could directly change from there)
