 Posted: Tue May 15, 2012 9:50 am Post subject: Network between three machines connected via switch |
 |
|
I have three machines connected raw via a switch. No router. No server.
Should it be as simple as static IP addresses via
| Code: |
ifconfig eth0 192.168.1.21 up
|
And subsequently other machines .22 .23?
Both machines report correct address when running ifconfig after the above call on themselves.
When I do this I get destination host unreachable when doing a ping with raw ip address.
As there's no server or router involved I can't define a gateway?
Any obvious thoughts? |

What does netstat -rn return? Please add a netmask (e.g., 255.255.255.0) to the ifconfig command.

Apologies I did actually enter:
| Code: |
ifconfig eth0 192.168.1.22 netmask 255.255.255.0 up
|
netstat -rn returns
| Code: |
Kernel IP Routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo

What kind of switch (managed?) is used for this setup? I assume netstat -rn returns for all boxes the same information.

It's just a standard Netgear FS605 unmanaged switch.
Yes, netstat -rn returns the same for all boxes. |

This somehow does not look right:
| Code: | | 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo |
Did you add this route?

Hmmm. Not that I'm aware of.
I need to check back through some config files. This system is an embedded system that hasn't changed for a number of years and used to work in a client server environment with dhcp. I will post some more info later when I get chance to look at the files again.
Thanks for the input. |
