- Hello,
-
- I am trying to set the broadcast address for a bunch of machines running
- SunOS4.1.3. As installed from CDROM, there are two ifconfig lines in the
- /etc/rc* files. Both are of the form:
-
- ifconfig le0 hostname netmask + broadcast +
-
- I am picking up the correct netmask from our NIS server, however the broadcast
- address is being set to XXX.XXX.XXX.0 instead of XXX.XXX.XXX.255.
-
- I understand that I can easily edit each and every client's rc.local to change
- the '+' to the proper broadcast, but I was hoping to not have to do this.
-
- In addition, the Nutshell book _Managing NFS and NIS_ by Hal Stern mentions
- that the broadcast address will be set to either 0's or 1's depending upon
- "your system's choice of a default broadcast addreses" (pg 215).
-
- This leads me to believe that I can change the broadcast address from the zeros
- form to the ones form. Can anyone point me to where I should look to do this.
-
- Any help would be appreciated.
-
- Thanks,
-
- -John
