Connectivity between two BBAI64 with Ethernet Switch

this is an incorrect configuration. the ‘/24’ part of the IP indicates that 24 bits of the IP identify the network, and the remaining 8 identify the host. you have specified two DIFFERENT networks 192.168.64 and 192.168.65 … the two hosts will not see each other with this configuration.

if this is your only problem, you might get the two hosts to work by putting them both on the same network. I’m assuming that your switch does not support DHCP, that is why you need static IP’s… but they need to be on the same network (with different host identifiers … of course) … one example that might work is :
192.168.64.10/24
192.168.64.11/24

the .10 part and .11 part are just an example, any two different host id’s >= 1 and <= 254 might work if that is the only problem… In fact, if these are the only two hosts on the network, you might not need a switch at all, just connect both NIC’s with an ethernet cable and see if they can ping each other.

BTW just to round out the instruction, ‘/24’ networks are called ‘class C’, and ‘/16’ networks are ‘class B’. if you changed the ‘/24’ to ‘/16’ in your current configuration that also might work. Class C networks support up to 254 hosts, and Class B networks support 65534 hosts ( ( 64 * 1024 ) - 2 )…

with just two hosts you could connect them with a ‘/30’ IP (CIDR) … ‘/30’ networks support 2 hosts, plus one to identify the network and another IP to identify the broadcast address. try with the ‘class c’ IP’s first …

good luck
