WiFi doesn't work after system freeze. How to reinstall drivers?

$
0
0
I was browsing the Internet in chrome when my system froze, completely unresponsive. I waited an hour and checked back and it was still frozen, so I had to just power down by holding the power button. Ever since, my WiFi is gone. When I click on the little WiFi icon in the system bar up top, the "Enable Wifi" option is gone, and obviously no WiFi names are present. A proper restart does nothing, and I have no way to get a wired connection established.

Edit:
Code:

rfkill list all
outputs nothing.
Code:

dmesg | grep iwl
outputs nothing.
Code:

lsmod | grep iwl
outputs nothing.
Code:

lspci
outputs
Code:

3a:00.0 Network controller: Intel Corporation Device 9d21 (rev 21)
. And
Code:

sudo dpkg --configure -a
outputs nothing.

I've been suggested to reinstall my wifi drivers. How do I go about that, especially with no connection?

[ubuntu] Lost ethernet connection

$

Installed Ubuntu 16.4.1. added Gnome synaptic. Synaptic did not come up but was in the startup applications. I re-booted. When Ubuntu came back up, there was no Ethernet connection. I have NO Linux internals knowledge. Please advise what commands I need to enter to diagnose and/or restore the Ethernet connection. The network icon at the top of the desktop says networking is enabled but no network devices available. 'edit connections' shows nothing in 'Network Connections". I installed Ubuntu on the advice of a friend who said it did not need any 'tweaking' and would run right out of the box. I am stumped but can bring up a terminal screen and type commands. This post came from a Windows Machine since I have no Ubuntu network connection. Any commands I need to enter will have to be typed in from any response to this thread.

Thank you for the help

[SOLVED] denied browsing 16.04 ubuntu shares from any machine in the lan

So, there is some really "weired" problem with ubuntu machines. Actually I'd rather blame our, (and with this I am prone to blame myself, as well), ignorance about IP networking.
Slightly explained situation :
In the moment, I am having situation like this one :

- there are two pc's that I am currently observing in this post, (pc1 and pc2)
- in addition to it there are some android devices that should be able to browse any of those two
- all those are connected to the same wlan router-repeater

------------------------------------------------------------------------------------------------------------
the tricky part:
a pc2 is connected to this router via usb cable, but Ubuntu is treating this as standard ethernet cable and gave it a interface name "enx001e101f0000". Router is standard huawei gsm wlan router which can give wlan repatin service as well and in this situation this is what I have handy at the moment.
The pc2 pc plays some kind "logon and keep link alive" role since ISP in the place where I am residing in the moment is restricting access to ony one MAC address and for shameless ammount of money, so I decided to relay the internet to other guys in my surroundings sharing, though, a expenses for this one.

A pc2 is some kind of file sever too, and to this job I assigned one of my netbooks sitting unused uder the table.
PC1 is my comp which is used for any other purpose, and also need beeing able to access all the shares on pc2 as well as beeing able to share all files from it's dedicated folders as well.

Rest of this small "enterprize" users are standard internet users, and those who like to access files and folders shared over the, (let's say hiddennet).
I some ocasions this net should be able to serve some android devices in very same way.

PC1 and PC2 are both ubuntu 16.04 machines with enabled and running smbd services.
----------------------------------------------------------------------------------------------------------------

Here is what happend:

After installation of latest ubuntu 16.04 release, system worked perfectly until the moment where I had to reset it due to ubuntu "have frost" on PC1. All over the sudden, I lost filesharing ability of PC1 while I was able to browse and share all on tne PC2 .

-------------------------------------------------------------------------------------------------------------------
That gave me a challenge to dig out what could went wrong and here is what did after several days of digging through all other sollutions found on the net:
I have connected computers to the AP not paying much attention to the IP configuration. The internet still have worked even after all other stalled.
For some reason, PC1 have prioritzed IPV6 rather then IPV4 which was taken before all stopped. This caused some missconfiguration issues in the network, preventing me to access shares on the PC1.
--------------------------------------------------------------------------------------------------------------------
Sollution:
Just disabled IPV6 in all of network participating computers.


coclusion:
To all who may encounter similar problem,
since IP management of any network, (no matter how big and complex this one could be), is rather systematic topic, it would be good to pay attention to this detail.
In addition to this, one wanting to implement similar situation, should consider assigning IP adresses manually, or at least dedicate own IPV4 pool to the local network, hence avoiding a missconfiguration that happend in my situation.

All comments on this matter are more than welcome.

How to configure network for dhcpv6 address

$

0
Hello, I'm having trouble getting ubuntu 16.04 server to request/get a dhcpv6 provided IP address when the networking.service restarts or the server reboots. I'm able to manually run dhclient -6 and get a dhcpv6 provided IP address. Under normal operation I just get a autoconfigured/peer probed IP address that is based on the subet and mac of the server. This is my network configuration.

Code:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto ens6
iface ens6 inet dhcp
iface ens6 inet6 dhcp

I've attempted to change any system setting with ipv6 and autoconf in it to 0 but that doesn't seem to change how this system attempts to get an ipv6 address.

Code:

defaults (leaving out lo interface)
net.ipv6.conf.all.autoconf = 1
net.ipv6.conf.default.autoconf = 1
net.ipv6.conf.ens6.autoconf = 1

new settings
sysctl -w net.ipv6.conf.all.autoconf=0
sysctl -w net.ipv6.conf.default.autoconf=0
sysctl -w net.ipv6.conf.ens6.autoconf=0

after systemctl restart networking.service I still get a autoconfigured IPv6 address not one provided by the dhcpv6 server.

Any idea how to make this system request a dhcpv6 provided IP instead of doing the autoconfig thing?

Thanks

I am having this problem also. I have done what is suggested here, on youtube, on help.ubuntu, to no avail. I have been struggling with this for almost a week. I have a Lenovo x230 with the only operating system being Ubuntu 16.04
The laptop sees and connects to wifi, but I am unable to get on the internet wirelessly. Other devices (windows, android) have no trouble. I have to use a wired connection.
Please help. I tried to make sense of the output, but I'm a newbie to linux. Here are the results from the wireless script:

Hi all, I'm pretty new so please forgive if i'm stupid at this :)

My fresh install of Xubuntu 16.04 cannot detect Wi-Fi networks. Wires networks are fine.

I've found a few other articles on this but none have helped so far.

'lspci' outputs this-

Qualcomm Atheros QCA6174 seem to "dislike" AC

$

I have a Qualcomm Atheros QCA6174 adapter with the firmware taken from https://github.com/kvalo/ath10k-firmware and experience connectivity issues with a hidden 5 GHz AC network.

When the network is initially added it usually manages to connect, but once disconnected (either manually or via a reboot or suspend) it struggles to reconnect. Either it takes up to 2 minutes, while its state is toggling between inactive and scanning or it does not connect at all and mentions a "failed activation".

The interesting part is, it seems to work fine when the same network is made visible, respectively does not seem to have the same issues with a hidden N network on 2.4 GHz.

Anyone an idea what is going on and how it could be fixed?

Hello.

I cannot connect to WiFi, there are no connections. WiFi was working really well when I was using Ubuntu 14.04. So, I changed to Lubuntu 16.04, but some days later my WiFi connection dissapeared. Now, I have returned to Ubuntu (to maybe fix the problem), this time in its version 16.04, but I still have no WiFI connection.

Any idea?

Apache2 issue?

$
0
0
I'm running a python script on my server every once in awhile the script seems to bind a port and I have to switch it. I tried lsof -i :myport | grep "python" | cut -d " " -f2 | xargs kill -9 both with -f2 and -f3. This did nothing python still gives the error errno98 address already in use.

But this command did work fuser -k 5004/tcp, the issues is I think since it kills the process that opened that port it's killing apache maybe. I think this because nmap only shows ssh open port nothing else.

If I remember open with iptables restart the service for Apache2 and networking I still get nothing. I sometimes also get a forbidden error from Apache2 instead of a cannot connect message with I get from the site if I go to the port but the Web app hasn't started.

[ubuntu] In Search of Support Setting up Port Forwarding

$
0
0
Hello, I'm a relative newbie, setting up a nas system

I'm using Ubuntu Server 16.x, running Owncloud 9.x and Ajenti web management interface

I've got everything working nicely - OC & Samba can see my other system devices, I can access OC internally on http and Ajenti on https - and even setup my first cron jobs and groups :)

However, I'm trying to setup access to OC externally, over https

(At this time, I have no intention to access ajenti externally, which runs on port 8000)

Because I also run another device using the standard http & https ports, I need to use different ports. I've gone with 89 for http, and 489 for https (no real reason behind those, may well change them)

Using port 89 for http, I've managed to setup external access to OC. However, my efforts to setup https (be it internally or externally) are proving a little futile - and I lose access to both OC and in some cases Ajenti - and have conceded I'm swimming just a little out of my depth now!

In my /etc/apache2/ports.conf file, I've updated to


Code:

Listen 80
Listen 89


<IfModule ssl_module>
#      Listen 443
Listen 489
</IfModule>


<IfModule mod_gnutls.c>
#      Listen 443
Listen 489
</IfModule>

And, in my /etc/apache2/sites-enabled/000-default.conf file
Code:

<VirtualHost *:89>
        ServerName sub.domain.com


        # Redirect permanent / https://sub.domain.com:489/


          ServerAdmin webmaster@localhost
          DocumentRoot /var/www/owncloud


        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

(At one point, I have *:89 separate to *:80 - but it didn't seem to like me having both in that file, so just updated 80 to 89)

When I un-comment the redirect, I do get 'redirected' to port 489, but get a page can't be loaded

I tried adding this to the same file...

Code:

<VirtualHost *:489>
        DocumentRoot /var/www/owncloud
        ServerName sub.domain.com
</VirtualHost>

But that made no difference either

I've seen references to editing virtual hosts within httpd files - but couldn't track these down and wondered if they were the same thing as the default.conf file I'm editing.

Happy to do reading, and have no problem doing trial & error - but now worried I'm going to screw something up properly, so would welcome any pointers on where I'm going way off piste.

Thank you!

[ubuntu] Networking Ubuntu with windows PCs

Hello guys,

I have a simple requirement to network 3 devices.

One of the device is running Ubuntu 15.04, and has 2 Ethernet interfaces [eth0 and eth1].
The other two PCs are running Windows 8 and each has 1 Ethernet interface.

The network setup is as follows:

network.png

The IP address assignment is as follows:

Ubuntu device (B)
eth0: 192.168.0.1
eth1: 192.168.0.2

Windows PC (A)
192.168.0.3

Windows PC (C)
192.168.0.4

After the above setup, the desired result is to enable A, B, and C to ping each other, however, I'm getting below result:
  • Only A and B can ping each other
  • B and C cannot ping each other
  • A and C cannot ping each other


Please how can I achieve the desired result? Is there any routing configuration that needs to be set on the Ubuntu system?

Ubuntu not finding my wireless driver

Hey all,

First of all, I'm very new to Ubuntu. I've recently uninstalled Windows (sick of having problems) and installed Ubuntu on my Dell laptop.

I'm not able to use wireless internet. When I go into "Additional drivers" there is no wireless driver there. I'm currently using an ethernet cable plugged into my modem.

My wireless card is Intel Centrino Wireless-N 2230 if that helps.

Thanks for the help.

Heres my wireless script:

Hello,

my dlink dwa 140 wireless adapter disconnects every 10 - 5 minutes sometimes it lasts longer, but then it disconnects. very annoying, with windows running on the same computer and same network card it works without any problem. (now i only have ubuntu 16.04 though )

what should i do to fix this? i have tried searching other threads but havent found anything since most are very old.

There are a fair number of threads on this in various other forums and they say to put this in /etc/rc.local

rfkill block bluetooth

but it makes no difference. There is bug filed in launchpad here:

https://bugs.launchpad.net/ubuntu/+s...ux/+bug/750428

which refers to a kernel patch from a year and a half ago that solves this. However, this patch never seems to make it into the kernel
updates for this release. (Or if it did, it doesn't work for some reason.)

Anybody have a solution for this that does not require building and installing a custom kernel?
I do not use bluetooth at all, but I do use wifi, so shutting off the radio with the switch on the
side of the laptop is not going to do it.

Thanks.

Having problems connecting with WPA & WPA2 Enterprise with TLS security

I am running Ubuntu 15.10 and my wireless works fine. I can connect to a wireless network. I am only having problems connecting with a network that has WPA & WPA2 Enterprise with TLS security.

When I try to connect to the network it brings up a WPA & WPA2 Enterprise dialog. I change the authentication to TLS and fill out the fields. The connect button never becomes activated.

Help With GRE Tunnel

$
0
0
Hello, sorry if I post this in the wrong area.

I've been trying to set up a GRE tunnel for the past 2 days with no luck, I own an NFO VPS running Ubuntu Server and my main computer has Ubuntu in a VM, and also dual boot to see if VirtualBox is causing any conflict.

I've followed this tutorial completely - http://wiki.buyvm.net/doku.php/gre_tunnel

I can't ping Host A from Host B and vice versa, not a whole lot of documentation on how to troubleshoot this, especially for Ubuntu.

I'll explain how I did this so anyone can see if I messed up, I loaded the module and enabled ip forwarding. I'll give an IP for this example.

Host A: 123.123.123.123

Host B: 123.123.123.124


Host A
Code:

iptunnel add gre1 mode gre local 123.123.123.123 remote 123.123.123.124 ttl 255
ip addr add 192.168.168.1/30 dev gre1
ip link set gre1 up

Host B
Code:

iptunnel add gre1 mode gre local 123.123.123.124 remote 123.123.123.123 ttl 255
ip addr add 192.168.168.2/30 dev gre1
ip link set gre1 up


If any extra info is needed, I'll give it. Any help is appreciated.

Edit: PS I'm running Ubuntu 16.04 for this.
