Installed Sim 7.2.4 Got IP from DHCP but can not communicate




I just installed Ontap Sim on Linux box and everything worked except can not communicate on network..


Ontapsim> ifconfig -a
ns0: flags=848043<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        inet netmask 0xffffff00 broadcast
        ether 00:50:56:09:e1:96 (Linux AF_PACKET socket)
ns1: flags=808042<BROADCAST,RUNNING,MULTICAST> mtu 1500
        ether 00:50:56:0a:e1:96 (Linux AF_PACKET socket)
        inet netmask 0xff000000 broadcast



It can ping itself...

Ontapsim> ping is alive


But nothing else,

Ontapsim> ping
ping: wrote 64 chars, error=Host is down
ping: wrote 64 chars, error=Host is down

Your advise is appreciated...



did you manage to solve this issue?

I have the same problem...


Disable selinux and iptables on the linux box.  Also you can't access the IP of the sim from the machine running the VM.  Setting up the VM nic in promiscuous mode also will help, sorry didn't read that you tried that until now.


Thanks for your answer.

iptables and selinux already disabled.

The nic is put in promisc mode by the simulator when I start it.

It seems the simulator does not respond to arp requests...

ok I managed to solve: we had two nic eth0 and eth1 in bond. If you use a slave nic in the simulator, then it is not capable to communicate. So we modified in order to allow the simulator to use bond0 as its nic.

Then it worked


If you're running locally (on a workstation for example) you need to communicate with the simulator from another host.

However, pinging outside should work, I don't know what might cause this. Maybe your network card doesn't support promiscuous mode, or the switch discards all packets that it receives from a "forged" MAC address (because that is what the switch thinks it sees)
