在嵌入式Arm机器上设置SSH服务器

Question

I have an Arndale board and an x86 desktop machine, both running Linux (Ubuntu on ARM and Debian on desktop, I think). The machines are connected with a straight ethernet cable; it shows up as "eth1" on the desktop and "eth0" on the ARM machine. I want to have the ARM machine run an ssh server, so that most of the development can happen on the desktop machine. How do I configure the network interfaces and ssh to accomplish this? I already have openssh services running on both machines.

This is what I tried (it's probably silly and wrong): on the desktop machine I added these lines to /etc/network/interfaces

iface eth1 inet static
    address 192.168.168.1
    netmask 255.255.255.0

and then executed ifup eth1 . These are the output of ifconfig :

eth1      Link encap:Ethernet  HWaddr 00:e0:4c:03:0f:56  
          inet addr:192.168.168.1  Bcast:192.168.168.255  Mask:255.255.255.0
          inet6 addr: fe80::2e0:4cff:fe03:f56/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:8 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:648 (648.0 B)  TX bytes:468 (468.0 B)

I set the address of eth0 on the ARM machine likewise as "192.168.168.0". I then tried to ping the ARM board (192.168.168.0) from the host machine, and nothing happens. I tried to arp the ARM board's MAC address, and it doesn't work either. What should I do? Have I got something mixed up or mistaken?

Thanks

Answer 1

With a 24 bit subnet mask, the .0 and .255 addresses are not usable for actual devices. You might try setting your embedded linux to use .2 as its address and see if that fixes your problem.

Answer 2

You can do below way.

#eth0 down
#ifconfig eth0 192.168.6.14 netmask 255.255.255.0 broadcast 192.168.6.6
#eth0 up

The IP address I have used is for an example you have to use the required IP for your server. In My case the Target IP is 192.168.6.14 nemask is 255.255.255.0 and gateway is 192.168.6.6.

Then it will start pinging. Hope this helps.
