DL380 G7: Not able to access ILO on DL380 via ssh from a client

Solution 1:

From your client, run a quick scan to see which ILO ports are open. Something like nmap -p22,80,443 10.247.172.70 should show the status of the common ILO ports. You'd minimally need port 22 to respond as "open". Ports 80 and 443 are for web management.

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2012-04-12 10:09 CDT
Interesting ports on testilo.abc.net (172.16.16.23):
PORT    STATE SERVICE
22/tcp  open  ssh
80/tcp  open  http
443/tcp open  https
MAC Address: 1C:C1:DE:78:04:F8 (Unknown)

Nmap finished: 1 IP address (1 host up) scanned in 0.187 seconds

If the nmap output shows the ports as filtered, talk to whomever manages the firewall/routing between subnets and indicate that you need inbound SSH (tcp port 22) open to the ILO.
