Ping multiple devices via multiple NICs

Hello everyone,

I have an old pentium 3 computer that has ~7 NICs installed. These NICs are attached to modems and other networking equipment.

According to the linux ping page on computerhope.com, it seems that one could send a ping from a certain specified NIC. How would one go about this?

Thanks!!!

how about

Code:

---

ping -I interface destination

---

Thanks

So I run iwconfig which says I have eth0 and eth1, as well as 2 other things.

How would I ping google.com or 4.2.2.2 from one of the network cards?

I tried the following

Code:

---

ping -I eth0 google.com

---

or

Code:

---

ping -I eth0 4.2.2.2

---

neither worked

Actually, it looks like it was some sort of wiring mishap.

Now that I can ping from a specified NIC, is there anyway to have multiple pings running? ex: one terminal window pings via eth0, and another pings via eth1, or perhaps both via one terminal??

Thanks

why can't you just run the command in different terminal sessions?

window1: ping -I eth0 Google
window2: ping -I eth1 Google

as far as running it all in one session - no.

The primary nic (eth0) is able to get a ping back from 4.2.2.2, however eth1 returns a "host destination unreachable." are there any settings i would have to modify in order to be able to ping from several nic's (on the same machine) simultaneously?

it looks as if only one nic is able to ping out at any given time.

so what does your routing table look like? what about ifconfig?
