[SOLVED] Ubuntu Server 16.04 VirtualBox IP Not Working

Hi,
So I have Ubuntu 16.04 Server installed on Virtual Box 64bit, and I'm using Apache but have no way to use a web browser that is connected to the same network as the virtual machine to see what is being displayed on that IP.
When I type
Code:
ifconfig | grep addr
this comes up: http://prntscr.com/bw7eti.
192.168.1.204 - refused to connect.
192.168.1.255 - might be temporarily down or it may have moved permanently to a new web address

192.168.122.1 - took too long to respond.
192.168.122.225 - took too long to respond.
127.0.1.1 - blank white page.

My Virtual Box Network settings are:
Attached to: Bridged Adapter
Name: Intel(R) 82566DM-2 Gigabit Network Connection.
Adapter Type: Intel PRO/1000 MT Desktop (82540EM)
Promiscuous Mode: Allow VMs
MAC Address: 0800274926A
Cable Connected - Ticked.

Thanks!

Missing: wired connection

I run Ubuntu 16.04 65 bit.

Yesterday I did some packages upgrade, after rebooting my box (without wifi) the wired connection has gone.

ifconfig says that a device named enp3s0 appeared:
Code:
mune@lello:~$ ifconfig

I modified the file /etc/network/interfaces and the network manager:
Code:
mune@lello:~$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo
iface lo inet loopback

auto enp3s0
iface enp3s0 inet static
        address 192.168.1.2
        netmask 255.255.255.0
        gateway 192.168.1.1

auto eth0
iface eth0 inet static
        address 192.168.1.2
        netmask 255.255.255.0
        gateway 192.168.1.1

and pinging the modem isn't working (where 192.168.1.1 is my modem/router/gateway)

Code:
mune@lello:~$ ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

^C
I think that getting the list of the recent upgraded packages it would be possible to identify the responsable and after downgrading it revert back to wired connection.

The router and cables are ok because some other device works.

Moreover the wifi part of the router works (now I'm connected with a wifi dongle).

Googling I've found oyer got the sane problem but no 3D offered a solution.

DNS & DHCP configuration

Good Morning,

I am trying to setup DNS and DHCP updating of DNS on my home LAN, but I think my configuration is not right because I do not believe DHCP is updating DNS. I can however browser the internet just fine, so forward resolving is working.

subnet: 192.168.55.0
gateway: 192.168.55.1
ubuntuws01 : 192.168.55.254 (DNS bind9 and DHCP isc-dhcp-server running on this host)
domain: lan.geekhelp.co.nz

I have a few coomputers on the LAN, mainly windows.

Conf files:
named.conf
Code:

include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";

        // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

AR9485 WiFi and Bluetooth not starting on boot, Ubuntu 16.04

July 23, 2016, 5:55 am

I have replaced my wireless card in my laptop last night as the previous one stopped working.
The new card is Qualcomm Atheros AR9485, I found it much better than my previous wifi card as it has better signal, doesn't drop connection and bluetooth is working, the only thing is neither the wireless or bluetooth work on startup so I have to suspend my laptop before I even get to log in which is a bit annoying, after it wakes up everything is working perfectly.

I ran the wireless-info script twice, before I suspended the laptop and after and compared the results with "sdiff". I noticed that
Code:
bnep,ath3k,btbcm,btrtl,btusb,rfcomm,btintel
were being loaded only after I suspended the laptop so I added them manually to load on startup which they do now but that hasn't fixed my problem.

Here's the full output of my wireless-info script of both before (left column) and after (right column) suspending
results.txt.tar.gz

Also in dmesg it looks like the wireless and bluetooth card doesn't go on until after the wakeup
Code:
[  694.053141] PM: Finishing wakeup.
[  694.053145] Restarting tasks ... done.
[  694.131556] usb 1-1.3: new full-speed USB device number 4 using ehci-pci

Is there any way to force this device to be enabled on startup?

WiFi Issues with Qualcomm Atheros QCA6174?

Hey guys, so I'm relatively new to Ubuntu and just installed Ubuntu 16.04 on my laptop (MSI gt72 dominator...)

I love it, and I finally got pretty much everything working, but I'm having one very frustrating issue. Wifi works just fine, but my connection to the internet will stop working a few times an hour. I'll remain connected to a WiFi network, good signal, but the internet will just stop working. I then disconnect and reconnect and it works again. This makes gaming and other things a real pain. Is there a wireless driver I should install that's more reliable than whatever one I'm using now? Also, I've noticed a general slowdown in speed. I used to get around 60 Mb/s, now I'm at around 8 Mb/s.

My Wireless Card:
Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 20)

network issue, eno1 not eth1 interface

I have a new ubuntu 16.04 server install with an xubuntu desktop. The server is running avashi and smb and appears in the clients' finder window. I have ssh setup and working and I can use a remote terminal to access the server. I cannot find a way to remotely access the desktop in any usable way. The client computer(s) run OS X el Capitan (10.10 I think, I have lost track). The issue seems to be something to do with the network settings.
In OS X I can see the ubuntu box but not access it. It will not accept the (correct) password. I can log into the ubuntu box using nomachine from a client, but cannot connect to any of the OS X machines using ssh. The ethernet interface is called eno1 not eth1 as I expected. This seems to be the only part of the puzzle that is not what I expected. What am I missing and what do I need to do to fix it? Googling hasn't provided an answer, so any assistance will be appreciated.

[xubuntu] Ralink RT3290 causing problems

Okay, I hope there are people who like to solve these kind of problems online. :)

I have CQ58-250SM compaq hp laptop, and it's... no good.

It suddenly restarts in windows, fails, blablabla... So I gave linux a shot, because I need only couple of things: Wifi support, browser, videos, music, simple word processor.

I tried Lubuntu, machine keeps restarting, then I tried RAM only systems, Linux Puppy, which works great, and Porteus, also great, but my wifi is not supported anywhere (as well in lubuntu, really buggy)



My question is - can you explain a complete linux noob how to install wifi drivers without active internet connection (I can download files on my desktop and transfer them to laptop) so I can use my wireless adapter in any distro?
I'm downloading Xubuntu atm and will try it, but I think I will have same problem as with Lubuntu - device not ready or I could not find module at all like on puppy.

Thanks in advance!

Config Files iptabls bzw. Stop-Skript bei Start-up

Hallo Zusammen!

Ich habe mich anscheinend versehntlich mittels iptables von meiner VM ausgesperrt und komme mittels SSH nicht mehr darauf. Der Fehler ist noch 100%ig verifziert, aber ich denke es liegt daran. Ich habe jedoch die Möglichkeit das Volume an eine andere VM zu hängen. Jetzt war meine Idee:

1. Die Config-Dateien "manuell" zu bearbeiten oder
2. Ein Start Skript zu schreiben dass die iptables erst mal flusht.

Weiß jemand von euch wo die Config unter Ubuntu 14.04 standardmäßig liegt bzw. wie ich ein Start-Skript platzieren muss damit es beim start ausgeführt wird?

Danke für eure Hilfe!

[ubuntu] Ubuntu as a Chromecast Audio receiver?

July 24, 2016, 11:45 am

Hello,

I have a Chromecast Audio device. And mighty fine it is too - it allows me to play music from my Android 'phone to an amp and set of speakers wirelessly, with very good sound quality. I'm a big Android user and it's a great device.

However I've wondered whether there is any way of setting up an Ubuntu machine as a Chromecast Audio and 'casting' music to it from my Android 'phone? i.e. Is there a way of configuring a Ubuntu machine to present itself to a network as a Chromecast Audio and play music that is cast to it?

The reason I ask is that you can use two Chromecast Audio devices together to play music in sync, thus giving you effectively a multi-room audio system without needing to wire loads of sets of speakers in. If I could make several Ubuntu laptops work as Chromecast Audios then I could play music in all the rooms in my house simultaneously. (I know I can play music from one Ubuntu machine to another by configuring them as DLNA sinks but it's not possible to make them play without differing lag times between the machines, which makes them un-listenable.)

All help welcomed, thank you. Please do ask if my question doesn't make sense.

(Mods: I wasn't sure where to put this topic- I couldn't see a dedicated 'Audio' sub-forum so have put it in the 'Networking' one. Please do move it if there is a better place for it.)

[ubuntu] Copying files between NFS folders from Ubuntu Client

July 24, 2016, 1:25 pm
$

I have a folder share from my Synology NAS server that was mounted as a NFS folder on my Ubuntu MATE client.
I think I lost some files while moving files from one folder in that mounted path to another folder inside that same mounted path.

The scenario is like this:
  • I started to copy some photos that I've taken from one folder inside this mounted share to another all while using Caja.
  • What I noticed was that Caja didn't show file copy progress even when I did several folders at once.
  • The folders appear right away to the new location and since these were just in JPEG format I figured it was a fast transfer and was done.
  • However when I open the folder not all the files are there.. Eventually for most of the folders, the JPEGs and RAW appeared.
  • I also want to mention that I started renaming the folders to match the date the grouped photos were taken.



Afterwards I noticed one folder has 0 files contained inside.
Performing in a terminal: "ls -l" also shows nothing inside the new folder. When I look at the old location, the folder is no longer there (it was moved from that location).

So I think I lost files inside the folder during this transfer and renaming. I'm 99% sure, not 100% because I didn't have a backup.
Afterwards I made sure to backup all my family photos to ensure nothing else like this happens in the future.:mad:

My questions are:
  • Is there anyway possible I can recover the folder?
  • How can I modify CAJA to show file progress (would be handy in the future)..
  • Are there any logs I can look for to see if the folder had contained and lost some files?
  • Should I stick to terminal for file transfer in the future?



Thanks in advance!

I'm trying to get Cisco AnyConnect to run in 16.04 without success. I keep running into the same error message and AnyConnect will not run. Here's the error message I get:

Code:
Warning: vpnagentd.service changed on disk. Run 'systemctl daemon-reload' to reload units.
If I run systemctl daemon, the command processes and nothing changes. AnyConnect will not run. The icon appears as though the program is installed but when I click it, the icon appears in the menu bar momentarily, goes away, and nothing more happens. I've run a system monitor to watch what happens but I don't see a Cisco or AnyConnect process run.

Any ideas of what to change?

BTW, AnyConnect is required by my workplace. I can't use OpenConnect or any other vpn software.

Hello

I have been using Xubuntu 14.04LTS
My computer is a Lenovo Z570
It is configured for dual-boot Windows 7 which I hardly ever use.
I have been using a wireless connection to a SilverCrest repeater.
Normally this usually works fine, but sometimes it disconnects, even though the signal strength is excellent.
While trying to resolve this problem I have somehow inadvertently ruined my network connection.

All Settings > Network now shows Wireless Hotspot ON & Aeroplane Mode OFF
Whenever I try to switch Wireless Hotspot from ON to OFF the Network window closes.
Consequently I am unable to get online wirelessly via Xubuntu.

I can get online via Windows 7 when it is connected to the main modem router.

I have updated the BIOS to version 45CN38WW

I am using another computer running Windows to get online, so I can type this.

On my Lenovo I have tried following : Wireless connection troubleshooter

I've been following the directions on this thread https://ubuntuforums.org/showthread.php?t=1163482 but I still have the same IP. Please do not open a discussion about why I want a new ip, or spoofing my MAC address to get a new ip, being that I've not only tried that, but im pretty sure that this can be done without any spoofing a mac. :)

I have the following running equipment::
ubee dvw3201b - Cable Modem
netgear wnr 2000 Netgear Router

When i use these commands in my terminal my ip stays the same::

Code:
sudo dhclient -r
sudo rm /var/lib/dhcp/dhclient.leases
sudo dhclient
Please can anyone help me with this???? Thanks

İ am using iptables+ squid proxy server in my firewall. i can see 80. port trafic in squid logs.
But i can not other ports.
i think wireshark is not useful program.
i want to see package size,source ip+destination ip +source port +dest port etc...
i think top,htop,tcpdump is very single program
Which program is best useful?

The wireless is not working, Ubuntu 14.04 and I have Acer Aspire E15-E5-573G.
I used some "guides" from the forum or askubuntu, but didn't worked :-(
Someone can help me?

PS: before worked, but I updated my laptop ( the daily updates from linux), and everytime I made the update my wifi stoped working, but every time I could fix them with "guides" I found here, but now no one worked :-(
