Hello, I have a LAN (Ethernet) with a mixture of systems on it. Some of the systems are running 4.2 based TCP/IP, others are running 4.3 based TCP/IP. I can't change the broadcast address (129.130.0.0) on the 4.2 systems. The broadcast address on the 4.3 systems is 129.130.255.255. This is really no problem, except that the 4.2 systems don't see broadcast packets from the 4.3 systems (the 4.3 systems do see the 4.2 broadcast packets). I'd like to change the 4.3 broadcast address to 129.130.0.0 so everyone can see everyone. But is this likely to break anything? A brief list of my systems: 4.3-like networking: Sun 3s (SunOS 4.0) VAX 11/780 (More/bsd (4.3BSD + NFS)) Harris HCX-9 (HX/UX 4.0 (4.3 sorta + NFS)) 4.2-like networking: ATT 3B2s (SysV 3.0 + WIN/3B 1.1) ATT 3B15s (SysV 2.1 + WIN/3B 1.1) Will changing the broadcast address break things like YP or NFS? Thanks for any help. Please email responses and I'll post a summary.
