I am trying to get a list of wireless networks nearby while the adapter is in p2p mode, but iwlist returns the following error:

Please let me know, if there is any other way for scanning wi-fi networks.
I have an issue with the internet in my VMWare guest machine working very randomly (mostly not working) and I am not sure what the issue might be.
Sometimes the internet works (this also includes possibility to ssh to the host), but most of the time it doesn't.
Restarting networking doesn't help, nor any ifdown/ifup's. The only situation when it might start working is restarting the whole VM. And even then it starts working perhaps one time in 10.
The only potential issue I have noticed so far is that when it doesn't work, VM network adapters' MAC addresses are swapped - while if it works, they are as configured.
Details:
host: OS X El Capitan 10.11.4 running VMWare Fusion 8.0.1
guest: Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux
VMWare virtual machine network settings:
Network Adapter 1 - NAT - static MAC address 00:50:56:38:CC:21
Network Adapter 2 - Host only - static MAC address 00:50:56:38:CC:22
In my virtual machine .vmx configuration file I have this (related to the interfaces):
ethernet0.present = "TRUE"
ethernet0.connectionType = "nat"
ethernet0.wakeOnPcktRcv = "FALSE"
ethernet0.addressType = "static"
ethernet0.linkStatePropagation.enable = "FALSE"
ethernet0.pciSlotNumber = "33"
ethernet0.address = "00:50:56:38:CC:21"
ethernet0.startConnected = "TRUE"
ethernet0.vnet = "vmnet2"
ethernet0.bsdName = "en0"
ethernet0.displayName = "Wi-Fi"
...
ethernet1.present = "TRUE"
ethernet1.connectionType = "hostonly"
ethernet1.virtualDev = "e1000"
ethernet1.wakeOnPcktRcv = "FALSE"
ethernet1.addressType = "static"
ethernet1.linkStatePropagation.enable = "FALSE"

ethernet1.address = "00:50:56:38:CC:22"

Here I can see the only difference - the MAC addresses are the other way round, compared to how they are configured.
When internet works:
from the guest, pinging all 192.168.195.* works fine (.200, .2 and .1)
from the host, I can ping myself (.1) and the guest (.200), pinging .2 gives me 'Request timeout' error
When it doesn't work:
from the guest I can ping myself (192.168.195.200), but pinging any other 192.168.195.* (.2 or .1) gives me 'Destinaton Host Unreachable' error. Same when pinging the internet (for example 8.8.4.4)
from the host I can ping myself (192.168.195.1), but pinging any other 192.168.195.* (.2 or .200) gives me 'Request timeout' error.
Any idea why this might be happening, and what else I could try?
Thanks!
The issue is solved now.
I tried the workaround described at https://communities.vmware.com/message/2350978#2350978 - generally creating a new VM using the existing VMDK virtual disk (which re-created all the external VM settings) - it worked flawlessly, even though being a little overkill.
Just in case I have kept the copy of the original problematic VM, and then, after getting help from the VMWare employee - which suggested removing the NAT adapter settings (all ethernet0. entries) from the VM's .vmx configuration file, then removing the network adapter itself, and then re-adding it - everything started working perfectly.
Guess I just had some old settings in the .vmx file, from previous versions of VMWare, or old VM configurations...
Objective:
Main objective is to the details as below (The JSON part I will do ,getting the below information using command is a problem ,from Java I can run once i get the command )
ether_stat_s
{
port_name [16] : **Name** of the Port(**Can get from ifconfig -a** )
port_udev_id; **ID** of the port ( **No idea from where I can get ID** )
mac_address[32] Mac address (**Ifconfig -a** )
int speed; // 1 = 100 Mbps/ 2 = 1Gbps/ 3 = 10 Gbps(**Only know about wlan0 and eth0**)
uint64_t rx_pkts ( **Ifconfig -a**)
uint64_t tx_pkts (**ifconfig -a**)
};
Work So Far:
I have used the below command to get all the ports
command : ifconfig -a

I am able to get Speed of eth0 using ethtool (but it does not give me speed of wlan0 ,docker0,l0) ,I can get speed of wlan0 using iwconfig,but is there any tool such as ethtool which can give me speed of all the ports in my linux .
Also am I going in the right direction on the getting all the port information on linux (ie:Using command ifconfig -a ,or /etc/sbin/network ) .Please can anyone guide me .
I have set up puppet learning VM on VirtualBox. I can ssh into it with:
ssh root#127.0.0.1 -p 2222
However, the guide says to do facter ipaddress, and ssh into the ipaddress that outputs. I get 10.0.2.15.
If I try that ipaddress, it does not work. I want to get it to work.
Also, I am supposed to be able to access the Puppet gui from https://10.0.2.15 and am not able to do that. I think the two problems are related.
I have 3 adapters set up. 1. NAT, 2. host only adapter, 3. bridged network.
For #1, I have port forwarding set up (am not able to ssh without it).

NICs
I don't see any IP assigned to your NICs except eth0. I assume this learning VM is based on centos, please configure your network adapters correctly first.
check:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network-scripts/ifcfg-eth2
/etc/udev/rules.d/70-persistent-net.rules
This is no puppet or virtualbox issue.
port forwarding
Accessing https://10.0.2.15 will not work, this is an internal NAT network IP. Please create an entry for your VMs NAT Adapter under Port-Forwarding, just map Host Port 10443 to guest port 443. If you try to access https://localhost:10443 in your browser you should reach the service running on this VM and listening on port 443.(Check if the service is running and the firewall/iptables is open on all needed ports).
Patrick is right. The configuration within the CentOS box is strange.
It's working for me under windows but on my Ubuntu system I had big trouble setting up the Training VM.
My Tip: just add 22 and 80 port forwordings in your virtualbox.
Change -> Network -> Adapter 1 -> Port-Forwarding -> add
Protokol: TCP | Host-Port: 2222 | Guest-IP: 10.0.2.15 | Guest-Port: 22
-> you may connect now by:
ssh localhost -p 2222 -l root
also:
Protokol: TCP | Host-Port: 8081 | Guest-IP: 10.0.2.15 | Guest-Port: 80
-> you may access the questguide via:
http://localhost:8081
Would someone explain this below output of ifconfig command. This PC is using USB IP4 Internet connection.
For example: why there is, inet6 addr: fe80::5a2c:80ff:fe13:9263/64 Scope:Link, assigned /
active on eth1, and why loopback is active.
Am trying to configure IPtables with minimum connections as possible and minimize the risk of intrusion.
I did not find an answer to this question.
With many updates and upgrades to Ubuntu since 12.04.

In the folder /etc/network you have the interfaces file, in which you can configure your Ethernet configuration. With something like this:
#Configure Loopback
auto lo
iface lo inet loopback
#The primary network interfaces
auto eth0
iface eth0 intet static
address X.X.X.X
netmask 255.255.255.0
gateway X.X.X.255
I hope this can help
