I am using the same ova image on both my local machine and another headless server, which is virtualized on some vsphere esxi server.
When running the VM on my local machine, I can access the SSH server of the guest via NAT (localhost:2222) as well as via host-only-network (192.168.56.111:22).
When running the guest on the headless server, I cannot ping the machine using the host-only-network. When I try to use the NAT, the port 2222 is open on the headless server, but the ssh connection times out as nothing is returned.
vboxmanage showvminfo shows the following for the network settings of the guest (same output on local machine and headless server):
NIC 1: MAC: 080027788420, Attachment: NAT, Cable connected: on, Trace: off (file: none), Type: 82540EM, Reported speed: 0 Mbps, Boot priority: 0, Promisc Policy: deny, Bandwidth group: none NIC 1 Settings: MTU: 0, Socket (send: 64, receive: 64), TCP Window (send:64, receive: 64) NIC 1 Rule(0): name = Rule 1, protocol = tcp, host ip = , host port = 2222, guest ip = , guest port = 22 NIC 2: MAC: 080027FBC41B, Attachment: Host-only Interface 'vboxnet0', Cable connected: on, Trace: off (file: none), Type: 82540EM, Reported speed: 0 Mbps, Boot priority: 0, Promisc Policy: deny, Bandwidth group: none
vboxmanage list hostonlyifs shows this, with the same values for my local machine and headless server:
Name: vboxnet0 GUID: 786f6276-656e-4074-8000-0a0027000000 DHCP: Disabled IPAddress: 192.168.56.1 NetworkMask: 255.255.255.0 IPV6Address: fe80::800:27ff:fe00:0 IPV6NetworkMaskPrefixLength: 64 HardwareAddress: 0a:00:27:00:00:00 MediumType: Ethernet Wireless: No Status: Up VBoxNetworkName: HostInterfaceNetworking-vboxnet0
vboxmanage list natnets shows this, with the same values for my local machine and headless server:
NetworkName: NatNetwork IP: 10.0.2.1 Network: 10.0.2.0/24 IPv6 Enabled: No IPv6 Prefix: fd17:625c:f037:2::/64 DHCP Enabled: Yes Enabled: Yes loopback mappings (ipv4) 127.0.0.1=2
ifconfig on my local machine and on the headless server shows the vboxnet0 interface with the same values.
I am out of ideas why I cannot access the guest's SSH server on the headless server, help is very much appreciated.
