How to ping from a specific interface if there are several interfaces?
costs Linux ubuntu server and after configuring the isc dhcp server, for some reason I started pinging from a different interface.
that is, eth0 looks at the local network, and eth1 looks at the router.
I want to ping a computer in LAN, but Destination Host Unreachable, since icmp is sent from eth1
How can I change it? what file to configure? or what?

Answer 1

Packets are sent according to the routing table. If you want to go through another interface - add the appropriate route. If there are multiple addresses on the same interface, ping has a key -Ito manually specify which address to send from.

Answer 2

# man ping

-I адрес
    Установить адрес источника в указанный. В качестве аргумента
    может выступать числовой IP-адрес или имя устройства.

Answer 3

ping -I "desired interface" 192.168.0.1
