I seem to be having a connection issue with my Netapp simulator. For example,
I can ping the Storage system from my Admin host
Nates-MacBook-Pro:/ betterplace$ ping NetappPING netapp.hsd1.ca.comcast.net (184.108.40.206): 56 data bytes 64 bytes from 220.127.116.11: icmp_seq=0 ttl=51 time=36.699 ms 64 bytes from 18.104.22.168: icmp_seq=1 ttl=51 time=37.365 ms 64 bytes from 22.214.171.124: icmp_seq=2 ttl=51 time=39.880 ms ^C
I can ping my admin host from the storage simulator
You didn't specify if the simulator was running in a VM, but I'm assuming it is. The fact that you can successfully ping bi-directionally between the sim and your MacBook, but not access certain ports (23 for telnet or 22 for ssh) makes me suspect your network interface has a firewall enabled on it. If the simulator is in a VM, make sure the guest O/S doesn't have a firewall enabled, or make sure ports for SSH, NDMP, HTTP, HTTPS, and SNMP are open.
If you're positive a firewall isn't the issue, provide more details about your environment's configuration.
