Hello everyone, I am a new Ubuntu user and I just installed Ubuntu 16.04 LTS on my HP Stream 13. I am eager to learn the Linux OS but I realized that my Broadcom wireless adapter is incompatible with Linux. From the terminal, I found that the pci id is 14e4:4365 rev 01. I saw the main sticky for driver installation of Broadcom adapters but I did not find this one here. Is there anyone who can help?

Dell Inspiron 3542, problems with Wireless and cabled internet

$

Hi. I bought a new Dell inspiron 3542 with windows 8.1 installed. I did a format, installed windows 10 and all the drivers with the correct order and then installed ubuntu 14.04.

Everything is working fine in windows 10.

On ubuntu on the other hand, i got 2 problems.

1) The problem in wireless is that my wifi is disabled by hardware switch and i can't figure out how to solve it.
Fn+prntscrn isn't working, although Fn+F2 or F3 works with the function related to these buttons.
I have also tried sudo rfkill unblock all and removed and replaced my battery, but the problem still occures.

2) The second problem is related with cabled internet. When i connect a cable, i got internet for 10-20 seconds and then nothing. The sign indicates that everything is alright and i that i got a cabled connection, but no internet. When i click the Cabled connection1, it reconnects and then again i have internet for 10-20 seconds.



Any ideas how to solve these problems?

Thanks in advance.

Fresh clean install of Ubuntu 16.04 with all updates done. Strange situation occurs after creating wifi connections to wifi network that does not broadcast SSID. After network connections are created successful when attempting to then select either of them the "connect" button is then grayed out. however, if I disable and re-enable networking the connection with then connect to one of the previously created wifi connections.

[ubuntu] lspci - no network devices

$

Hello, I have a Kangaroo (a mini desktop). It came with Windows 10. I wiped it and installed 16.04.
No wireless devices are found during installation.

After install, when I run lspci from the terminal, there are no network devices listed.
This is not a BIOS issue, I checked to be sure. Also, since I hadn't personalized Ubuntu yet, I wiped the PC again and put Win10 back just to check device manager. See image at the bottom.
WiFi is enabled and working correctly out of the box.
Windows Device Manager recognizes it as a Broadcom SDIO adapter, but no specific model number is given.

I am reinstalling Ubuntu to begin troubleshooting again as we speak. I do have a USB D-Link to use to download drivers/packages/etc. I simply cannot keep it connected to this device. The D-Link is needed on the desktop from which it came. The Kangaroo clearly has WiFi, so I'd like to get its own connection working. Any help would be greatly appreciated.

I of course started with the sticky: http://ubuntuforums.org/showthread.php?t=2214110
Again, lspci doesn't yield results. See image below.

I have also tried:

Access openVPN subnet via client on same LAN

$

Hello,

I've recently successfully configured an openVPN configuration on Ubuntu Server 14.04.4 and very happy with the performance.

My LAN is configured with a 192.168.1.* paradigm.
My openVPN is configured with a 10.8.0.* paradigm.

The openVPN server is on the same box where I host a Samba Share. I have a use case where I have a Windows Laptop where software is dependent on a consistent network mapped drive. When I am on the LAN, I cannot ping the 10.8.0.* address and when I'm on VPN, I cannot ping the 192.168.1.* address. I'm aware that the router doesn't recognize the VPN network, but I'm on a network with a AT&T router.

What is the easiest way for me to get my laptop to recognize a single IP address no matter if I'm VPN or local?

Thanks"!

[server] Enabling a second network interface causes the first to stop working?

$

Hi all.

Not sure where I'm going wrong here, but I can't get multiple NIC's to work on my virtual Ubuntu 16.04 server. The virtual network interfaces are on different VLANs, so the server should pick up 2 different IP's on different networks.

I have 2 virtual network interfaces connected to the VM. When I start up the server, only 1 NIC was configured in /etc/network/interfaces:
Code:

source /etc/network/interfaces.d/*

#The loopback network interface
auto lo
iface lo inet loopback

#The primary network interface
auto ens160
iface ens160 inet static
      address 192.168.5.10
      netmask 255.255.255.128
      gateway 192.168.5.1
      broadcast 192.168.5.127
      dns-nameservers 192.168.5.20

I have also confirmed that it will pick up an address on DCHP, but I wan't the static address configured..

So, having confirmed that I can ping the server from another workstation on that address, and I can ping from the server to the workstation OK, I then edit the interfaces file again to enable the other interface:
Code:

source /etc/network/interfaces.d/*

#The loopback network interface
auto lo
iface lo inet loopback

#The primary network interface
auto ens160
iface ens160 inet static
      address 192.168.5.10
      netmask 255.255.255.128
      gateway 192.168.5.1
      broadcast 192.168.5.127
      dns-nameservers 192.168.5.20

#The secondary network interface
auto ens192
iface ens192 inet dhcp

Just to confirm, in case you're wondering, I got the interface names from the following:
Code:

dmesg | grep -i eth
(truncated reply):
eth0: NIC link is Up 10000 Mbps
eth1: NIC link is Up 10000 Mbps
ens160: renamed from eth0
ens192: renamed from eth1

So, I reboot the server and check ifconfig. The server has an IP on both interfaces. This is where things get a bit weird.
Code:

#FROM THE SERVER:
ping -I ens160 google.com
PING google.com (203.5.76.208) from 192.168.5.10 ens160: 56(84) bytes of data
64 bytes from cache.google.com (203.5.76.208): icmp_seq=1 ttl=56 time=1.46ms

ping -I ens192 google.com
PING google.com (203.5.76.208) from 192.168.7.10 ens160: 56(84) bytes of data

From 192.168.7.10 icmp_seq=2 Destination Host Unreachable
From 192.168.7.10 icmp_seq=3 Destination Host Unreachable

But then I try to ping the server from another workstation:
Code:

$ ping 192.168.5.10
PING 192.168.5.10 (192.168.5.10): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
^C
--- 192.168.5.10 ping statistics ---
4 packets transmitted, 0 packets received, 100.0% packet loss



$ ping 192.168.7.10
PING 192.168.7.10 (192.168.7.10): 56 data bytes
64 bytes from 192.168.7.10: icmp_seq=0 ttl=64 time=0.387 ms
64 bytes from 192.168.7.10: icmp_seq=1 ttl=64 time=0.405 ms

3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.387/0.410/0.439/0.022 ms


So, after enabling the second NIC on the server:
  • I can ping out from the server on the ens160 interface
  • I can't ping the server from a workstation to the ens160 interface
  • I can't ping out from the server on the ens192 interface
  • I can ping the server from a workstation to the ens192 interface



So, does anyone have any ideas about where I am getting stuck and how to resolve this? Other posts I've looked at mention IP Routes, but I'm not very experienced with them, and couldn't get my head around the replied people were posting.

Thanks in advance!

Hello,

Two days ago I decided to upgrade the lubuntu version in my HP 245 G1 Notebook from 15.x to 16.04 and since then I am only able to connect to the internet with a wire, but no wireless connections show up. Here is my wireless hardware information http://paste.ubuntu.com/18601496/. I've tried following the instructions of all the forums I found online, but none of the procedures seem to work. I hope that someone in this forum is able to help me.

Never had this issue on other laptops. Just bought this Lenovo Thinkpad T61 and was getting it up and running. Won't let me connect to wifi with the PCI card or the USB AWUS036H external card i have. This is troubling. I will copy/paste any data i can to assist.

cannot connect to wired dsl cconnection...........

I have used a lot of linux distros previously and they ran smooth . Then I moved to windows and now again prefer linux . But I am facing a huge problem regarding my dsl connection . Everytime I switch to boot from Ubuntu 16.04 lts live or Linux Mint 18 or Steam os , I find wired connection detected but there is actually no internet network. I have added dsl connection from the network manager and also manually but the results are same . However, it is not the case with windows 7 or 10 .They are running good . My dsl connection requires ony username and password and I use no router as well .


Even Cublinux can setup my dsl connection and previous versions of Linux Mint like 17.3 also .Then why not Ubuntu .Fedora or Debian....


I am now badly in need of your help. Any good suggestion would be excellent. Thanks to all.........

[server] Network doesn't accept routes

$

Hi!

I do run a 15.10 based server (that has been upgraded from 14.x to 15.04 and then to 15.10). I need to add two static routes to it and that is only possible by manually setting them on the console. I found no other way to do that automatically after boot.

The basic configuration is dynamic, so a DHCP server is providing all network data to all machines including this server.

/etc/network/interfaces
... is mostly untouched for dhcp at eth0. I tried adding "up route add -net ..." in that file and the routes seem to be up for a short while as connections. Trying to connect over one of the routes gets a connection refused as long as SSH is not started. But before ssh comes up, the connections ceases. No response or "Connection time out".

I removed the routes from /etc/network/interfaces and installed the packet ifupdown-extra and added both routes to the /etc/network/routes file. This ends in the same result, while the kernel boots, the routes are available, but when all the services start, someone seems to clean out all routes and if fails over from "Connection refused" to "Connection timed out".

Another trial was to set the routes at the DHCP server. It results in the same behavior and I am actually out of ideas now.
I read a lot across the net and I am confused by if and how to enable or set NetworkManager-wait-online.service and its friends. However I didn't expect that adding two simple routes could be so complicated.

In syslog I can see some info:
Code:

A sidenote may be that I did not configure anything to reach out for 82.165.8.211... But I guess it is the connman trying to find out about the internet availability on that interface.

So any idea, of how to set NetworkManager and /etc/network/interfaces to simply add my two routes automatically? Cause manually it works fine...

[ubuntu] 14.04 ssh for multi-node cloudera cluster

$
0
0
Hello,

We have four computers running Ubuntu Desktop 14.04 that we have connected using a Netgear router. We are trying to use these four computers to create a multi-node Hadoop cluster using Cloudera Manager and CDH, which requires a network using SSH. We haven't done any configuring of the router, just used the default settings.

We have tried installing openssh-server using sudo apt-get install onto each of the computers. We used
Code:

ssh-keygen -t rsa
to generate a public/private RSA key. When we try to connect using
Code:

ssh username@hostname.local
, we get an error message: Permission denied (publickey). We also tried copying the RSA key over to the server from the client using
Code:

scp -P "22" ~/.ssh/id_rsa.pub clientusername@serveripaddress:~/.ssh
, but we still got the same error message: Permission denied (publickey).

How can we solve this public key problem? Does it have to do with our router settings? Is there a better way to cluster these computers for using Cloudera/Hadoop?

Thanks in advance.

[xubuntu] 16.04 Intel 7260 wifi stops responding after random amount of time

My laptop is a year and a half old and from the start I ran Xubuntu 14.04 with no wifi problems. I installed Xubuntu 16.04 recently and the wifi is giving me problems under it. It will connect and work correctly for a while, anywhere from a couple of minutes to, say, a half hour, but eventually it stops responding. Network manager shows it's still connected to the SSID and there are no error messages in syslog, but requests do not get through to the internet. I let it sit for 20 minutes one time and it never came back to life. If I click on the SSID again in the network manager applet, it reconnects and starts working again.

I have my system set to dual boot between 14.04 and 16.04. I went back to the 14.04 system, just to see that the network adapter wasn't going bad or something, and the wifi under 14.04 still works fine. I used it for a couple of hours with no freezes.

So far, I've tried using the iwlwifi 11n_disable=8 option, but that had no effect.

RTL8190 card not working

$
0
0
I recently decided to switch over to ubuntu from windows with my desktop and for the most part everything works. Unfortunately my wireless card is not. Unfortunately, the lack of wireless makes copying things over from it a pain as I have to do it by hand (I'm using a laptop right now).

That said it says the following if I type sudo lshw -C network:

Code:

*-network UNCLAIMED
description: Network controller
product: RTL8190 802.11n PCI Wireless Nework Adapeter
...

If you need something else from that let me know.

Because of this, I tried to get ndiswrapper to work. I think I successfully installed the driver as ndiswrapper -l says:

Code:

net819xp : driver installed
device (10EC:8190) present

However sudo modprobe ndiswrapper returns:
Code:

modprobe: FATAL: Module ndiswrapper not found.
My searches there have indicated that this can be fixed by installing ndiswrapper-dkms, as well as ndiswrapper-common, and ndiswrapper-utils-1.9. The latter were mentioned less frequently but when the initial package didn't fix the problem I installed them as well. Unfortunately that also doesn't work.

I also tried ndisgtk, which seem to work further into the process but returns a slew of permissions errors into the console as soon as I try to add a network with it, despite requiring sudo in the first place.

I attempted to compile ndiswrapper from source myself since that was also described as fixing the problem, but when I use "make" the compiler errors out on a comment.

Also "Additional drivers" only has drivers for my video card.

Thanks!

[xubuntu] WiFi for HP 17-y020ca under XUbuntu 16.04 LTSspontaneously disconnects very frequentl

$
0
0
I recently purchased an HP Notebook 17-y020ca and installed XUbuntu 16.04. This notebook has a Broadcom Corporation BCM43142 wireless card.
This wireless card was not originally detected, and I followed the instructions at the following to install support using the bcmwl-kernel-source:

http://askubuntu.com/questions/76558...n-ubuntu-16-04

After some futzing (resolved at http://ubuntuforums.org/showthread.php?t=2329060) the WiFi has been able to regularly detect networks and connect at least transiently.

However, I am encountering severe problems with the network disconnecting periodically on my home and certain other WiFi networks. These disconnections occur every 1-4 minutes or so -- so frequently that it is hard to stay connected, and the laptop appears to spend more time disconnected than connected! I am not yet certain if the problem occurs uniformly across all networks, but the problem certainly appears to occur in most networks. Occasionally, I will be presented with a dialog box asking for the WPA/WPA2 network password (with the correct password already proposed), but this does not occur during most connections/reconnections.

Because of this problem, my laptop is only barely in a working state on WiFi -- it is hard to get work done or use the web in a reliable manner.

Running the standard ubuntu forums wireless-info scripts gives the following (pastebinned to the default pastebin provider)
http://paste.ubuntu.com/18681683/

Given that this is a laptop which registers decent signal strength when connected, the problem seems to occur in close proximity to routers, and I therefore doubt any signal-strength issues.
Poking around elsewhere, I tried the following:

Code:

sudo cat /var/log/syslog | grep -e ipw -e firmware -e wpa -e wlan -e etork | tail -n55
The command above returned the below, showing the disconnection events. It seems worth noting the large number of disconnection (CTRL-EVENT-DISCONNECTED) and domain change (CTRL-EVENT-REGDOM-CHANGE) events, which are puzzling as they are not sought or caused by any change in networks caused by e.g., change in location.
(Please note that because I was posting from the wireless network, and have found that resetting the network can sometimes be fruitful, it is possible that the below includes one manual disconnection, but this common sequence is seen when connected with many other networks/routers in different settings, and without manual disconnection.

Hi all,

My question can be obvious to many of you, but I would still ask it.

I connect from my home or work pc to vps using ssh.

Is it possible somehow to use data of connected pc from my vps?

Like when I do ls on server, can I do ls from server on connected pc ?

Again, sorry if it is obvious or even stupid question.

Thanks ahead.
