I have two running machines That I want to communicate between with an ethernet cable.
machine A)
ethtool -i eth2
driver: nvethernet
version: 5.10.192-tegra
firmware-version:
expansion-rom-version:
bus-info: 6810000.ethernet
supports-statistics: yes
supports-test: yes
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no
5: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 3c:6d:66:02:c4:6f brd ff:ff:ff:ff:ff:ff
inet 192.168.2.101/24 brd 192.168.2.255 scope global noprefixroute eth2
valid_lft forever preferred_lft forever
inet 192.168.2.101/32 scope global eth2
valid_lft forever preferred_lft forever
And machine B)
ethtool -i eth0
driver: nvethernet
version: 5.15.136-rt-tegra
firmware-version:
expansion-rom-version:
bus-info: 6800000.ethernet
supports-statistics: yes
supports-test: yes
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no
5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1466 qdisc mq state UP group default qlen 1000
link/ether 48:b0:2d:a5:1a:d2 brd ff:ff:ff:ff:ff:ff
inet 192.168.2.102/24 brd 192.168.2.255 scope global eth0
valid_lft forever preferred_lft forever
inet 192.168.2.102/32 scope global eth0
valid_lft forever preferred_lft forever
They are both connected to a passive switch.
I can’t ping from A to B and the other way.
also running Nmap on each of them tells me they do not know each other.
what am I missing here?
machine A)
Distributor ID: Ubuntu
Description: Ubuntu 22.04.4 LTS
Release: 22.04
Codename: jammy
machine B)
Distributor ID: Ubuntu
Description: Ubuntu 20.04.6 LTS
Release: 20.04
Codename: focal
I tried using a crossover cable but it didn’t work so I thought a switch would do the trick
