VirtualBox networking between VM’s

I have 2 virtual machines that are currently configured as Bridge Network connected to the NIC… so that, my router gives them the IP address.

The problem with this, is that from the VM’s I can ping the router and the host and it works, however, if from host I try to ping any VM’s they don’t respond. Even when trying to ping from a VM to the other VM, ping does not repond.

When I change network setting to be Internal Network, the APIPA is assigned, so it is not my solution.

Is there a way to have all VM’s and host connect each other?


Question: Bad email regarding internal job networking?

So there is an internal job that I have been eyeing for. I emailed the manager as below , I know her but don’t really talk to her that much.

:I’m interested in job enrichment/career opportunity with finance. Would you have about 15’-30’ to meet up this week? I’d like to ask you some information about your group.
Thanks for your time!

But I have not heard back from her. I don’t know if I should follow up? Do you think my email is rude or too cocky? how can i fix the situation?

Why do open ports give no response in networking?

Nmap places ports in open|filtered state when it is unable to determine whether a port is open or filtered. This occurs for scan types in which open ports give no response. The lack of response could also mean that a packet filter dropped the probe or any response it elicited. So Nmap does not know for sure whether the port is open or being filtered. The UDP, IP protocol, FIN, NULL, and Xmas scans classify ports this way.

I read this on nMap port scanning basics.

How to use /etc/init.d/networking with password supplied by

I am staying at a friend’s house and have to use his Optus ISP to connect to the Internet. Optus requires that a supplied password be used to connect, something like:


Whilst my partner was able to connect with her Micro$oft laptop, I am not able to work out how to connect my Ubuntu Linux desktop.

I could be mistaken, but it seems likely that the script /etc/init.d/networking is what can do this for me. It seems that the command ifup called from within this script may be the means to do this. If I am right, then should the password be somehow passed to ifup as a parameter? How do I do this?

Or is this not even close to the correct way to connect?

Thank you,

MariaDB/MySQL refuses external Connections even when Skip-networking & bind-address are commented out

So I can’t get my db to allow remote access even when do all of the following is true:

When I run the ” SELECT user, host FROM mysql.user; ” Command in MySQL I get this:

| test | % | <-- I'm trying to make test able to be accessed from outside~ | root | localhost |

In my 50-server.cnf these are my mysqld settings:


* Basic Settings
user = mysql
pid-file = /var/run/mysqld/
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql

skip-external-locking // for some reason it’s appearing in hold but it’s hashed out

bind-address = // for some reason it’s appearing in hold but it’s hashed out


Version of Operating System:

Distributor ID: Debian
Description: Debian GNU/Linux 9.5 (stretch)
Release: 9.5
Codename: stretch

tcp6 0 0 :::3306 :::* LISTEN 1302/mysqld

When I check the port it’s open

I’m really confused….. Sorry I would images but I need at least 10 Rep

Pi Zero-W Networking between modem and router

I have the following equipment that I wish to utilise.

My internet connection is provided by way of a TP-Link M7350 3/4G modem. This does have a USB output that is capable of data sharing, but I don’t think that’s any use in this application.

My LAN is managed by an ASUS RT-AC51U. This has a USB port for a ‘back up’ 3/4G modem, but doesn’t appear compatible with the TPLink.

My next thought is to use a spare Pi Zero-W to bridge the gap, but I don’t know what terminology to search for, as networking is not my area at all!

I’m wondering if I can connect the Pi Wifi to the 4G modem (Yes, I can) but then route the internet traffic from 4G modem to Pi Zero Wifi, Pi Zero USB>Ethernet adapter, to the DSL port of the ASUS Router?

Is the Pi then an AP, Bridge, or something else?

I suspect the correct answer is in here, but unsure whereabouts Setting up a Raspberry Pi as an access point – the easy way


Recently did some unusual dist upgrade and now my networking doesn’t work

So I did check that my devices are registered both ethernet and wifi usb adapter lpci/lsusb they show up

when I check ifup or ifconfig I get no devices, ping fails

I am currently using i3-wm I tried to use the UI but I immediately get logged back out, not sure what’s up with that, I have space, I experienced this when my disk space was empty.

But yeah right now I can’t connect at all even with ethernet plugged in.

I say unusual dis-upgrade because this one was big and talked about installing new firmware and what not but as I mentioned the devices are found even the usb adapter…

I’m just trying stuff right now that I find on here
