Kerberos Authentication
Good morning. I am running Ubuntu 16.04 and am trying to get Kereberos authentication working. I create the same account on my Ubunu machine as I have in my Active Directory. However when I run the command:
#adduser <username>
This then asks me for the current Kerberos password and then asks me to enter a new Kerberos password. It then asks me to enter the 'user information' which updates the Active Directory account.
My question is - what command should I be running so that I don't need to enter a new kerberos password and update the user information?
Many thanks!

install TL-WN823N under linux ubuntu 10.04 on a NUC EBOX-3310MX-L3U4 from DMP Electro
Model: TL-WN823N
Hardware Version: V3
Hello
I'm new here in the forum so i hope i post it at the right place...
I'm trying for a customer to install the TL-WN823N on his NUC EBOX-3310MX-L3U4 from DMP Electronics.
Here is the page of the device itself if you need http://www.compactpc.com.tw/product....t=detail&id=85
I think the PCU and architecture is compatible with TL-WN823N
Ubuntu 10.04 is installed on it.
The USB device is detected but i can't succeed to compile the driver...
here is the log of the error
Firstly when i just unzipped the driver and followed instructions, i got error about unexpected syntax, and i understood the " ( " in the filename of the folder was not liked by the compile, so i renamed the name of the folder to something simpler like "linux" and retried again the "make" command but i came up with this above pasted error...
As you have guessed i'm not a Linux guru, i just want this NUC barebone able to go on Internet before giving it back to my customer who had windows XP before...
so if you could guide me step by step that would be great
If we suceed i will offer a (50% discount available in my store :p (kidding... but why not...)
Thanks a lot in advance

I Lost my Network Adapter I can get it back but.....
I use windows hyper V within this I have Ubuntu Server 18.4 LTS
When I reboot I dont' have any network adapters in the system.
I then run
dhclient eth0
this brought back my NIC, but now every time I reboot I need to run this command to get my NIC back, Anyway i can have the NIC back permanently and working even after reboot? I tried to run apt-get install network-manager and it installed but this didn't fix my issue. The machine will still reboot without the NIC until I run dhclient eth0 Using Ubuntu Server 18.04
When I reinstalled Ubuntu on the same Hyper V server using the same NIC card I dont' have any issues, I don't want to lose my old server and all the settings and data or I would have reformatted.
Thank you

[ubuntu] Wi-fi is not working inUbuntu 18.04.02 in Dell Inspiron
Hey everyone, I just instaled Ubuntu 18.04.02 inital but my wi-fi is not working. I try last 2 days and try almost all method that given in ubuntu forum and youtube.
But still not working for me. Could any one hep me out or i have to re-install ubuntu.
I already followed some of these steps:
git clone https://github.com/lwfinger/rtlwifi_new.git
Checkout to the extended branch
git checkout extended
Enter to the cloned folder
cd rtlwifi_new
Start installation
sudo make install
sudo modprobe -r rtl8723de
sudo modprobe rtl8723de
sudo apt purge bcmwl-kernel-source
sudo sed -i '/blacklist bcma/ d' /etc/modprobe.d/blacklist.conf
sudo sed -i '/blacklist brcmsmac/ d' /etc/modprobe.d/blacklist.conf
Reboot if wifi does not come on do:
sudo modprobe -v brcmsmac
sudo modprobe -v bcma
---------------------------------
sudo apt updatesudo apt install build-essential git
git clone https://git.kernel.org/pub/scm/linux...rt-iwlwifi.git
cd backport-iwlwifi
sudo make
sudo make install
The make step takes a few moments; please be patient.
Now, well write a conf file:
sudo -i
echo options iwlwifi disable_msix=1 >> /etc/modprobe.d/iwlwifi.conf
cd backport-iwlwifi
sudo make clean
sudo make
sudo make install
Reboot.
Please retain the files and these instructions for that time.

[ubuntu] ipv6 causes slow download speeds, but if disabled cannot use vpn
I posted this question on Ask Ubuntu but have not gotten any answers. Only an unhelpful "it's your router" comment that ignores what I have written there.
If anyone here can point me in the right direction...
Ubuntu 18.04 with low latency kernel.
I get horrible download speeds at times, especially with Steam, but also other streaming sites. I have found that if I manually disable ipv6, I get advertised download / upload speeds on my isp connection. If it is not disabled, things become really slow in a short period of time (like 2 Kbps). When I use my vpn service, everything runs fast because it disables the ipv6 stack, then re-enables it upon closing the vpn connection.
However, I got tired of having to manually disable when not using the vpn, so I permanently disabled ipv6 via grub. This completely disabled my vpn service. Even their support staff were unable to help. So I changed everything back to the way it was.
I have since disabled ipv6 in my router, which has helped increase overall speed when the network stack is at default (ipv6 enabled). Having both the router and Ubuntu ipv6 disabled increases my speed by several Mbps up and down.
To recap - ipv6, when enabled by default, slows down my Internet connection, but disabling it and only having ipv4 running makes everything faster. Disabling ipv6 in both the router and the OS makes things Speedy Gonzales. Disabling ipv6 permanently via grub kills vpn access.
Is there a way to permanently disable ipv6 so it does not break my vpn? Or some type of desktop script that can disable it manually with a click?
Thanks in advance!

[ubuntu] Wired networking problem after upgrading to 19.04
I have a desk top system with Win10 and several Linux operating systems on different hard disks. The Win10 is the normal boot system for compatibility with work but I can select to boot a Linux system by using F11 on booting. Since upgrading to Ubuntu 19.04 when I power off the Ubuntu and go back to Win10 I find that I am not connected to the internet via the cable connection from my Realtek PCI GBit card. Even though powered off, the Ubuntu seems to be retaining the connection. I have found that switching the main power off the computer for 10 secs the restarting clears the problem. I have reloaded a new Ubuntu 19.04 instead of the upgraded system but the problem remains. It is a problem I can live with but I would appreciate any ideas to correct it.

[lubuntu] Is there room for improvement for my WiFi ?
I am using a 4G hotspot. I connect to the hotspot using WiFi.
I am getting max speed of 2MBPS
I am not sure if my ISP is offering max of 2MBPS or is it something wrong at my end.
Is there room for improvement for my WiFi ?

Network Manager does not show wifi
Hello community,
I am a bit lost ... I don't know much in how all of this network stuff work and unfortunately for me after cleaning old kernel versions and rebooting I lost my wifi connection and do not seem to be able to reconnect !
I went through a lot of different posts but none seem to answer my problem for now .. :/
Indeed my network manager does not show any wifi and the command lshw -C network returns :

Hello!
I'm new to Linux and Ubuntu so I'm sure that this problem should be a stupid thing but my head is going to explode because of this!! So I hope the community can help me :confused:
I have a virtual machine with Ubuntu 18.04.2 with 2 interfaces: ens33 and ens34. I need them with static IPs, so I changed the /etc/network/interfaces with this:
Then when I restart the network service, I receive this error:
I don't know what I'm doing wrong. Am I configuring LAN networks in the wrong way?? This is an experimental environment for university. Can anyone help me and explain why I get this error??

No WIFI HW found after fresh install 19.04
Background:
I installed 19.04 today. The system was 18.04 and everything worked great. I am a gluten for punishment so I formatted the drive and installed disco. Ever since the WIFI card is not found. Ubuntu is acting like it is not installed. Again it worked perfect in 18.04 just a couple hours ago.
Currently I am USB tethered to my Moto x4 as I am on a floor of my house with no Ethernet.
Hardware:
Lenovo Ideacenter Desktop w/ AMD® Ryzen 5 1400 quad-core processor × 8

[ubuntu] No Wifi adapter found on Ubuntu 18.04.2 LTS
Hi everyone!
I recently installed Ubuntu 18.04.2 LTS on HP 17-ca0114ur laptop. I can't connect to Wi-Fi, it says that 'No Wi-Fi Adapter Found'. Wired connection isn't working too. I have Win10 on this PC, there were also problems with Wi-Fi in windows, I had to download drivers.

[all variants] High-capacity packet capture machine
Hi,
This is my thread here, trying to see whether there might be a simple solution to my problem.
I am trying to build a packet capture machine capable of handling 1Gbps and faster data streams. The target is to hit 10 Gbps or more, should hardware allow it. Right now, I am using Cisco UCS M5 server blade, with 2 x Xeon Platinum CPUs, ~380 GB RAM, and 4 x 2TB SSD in RAID 0, making sure there is enough capacity in each and every hardware element to sink that much data without choking. RAID controller is 12 Gbps version again, to make sure there is no choke point. I installed Ubuntu 18.04.2 server version, with minimum packages to lower the system load.
I am using Melanox MT26448 and Intel X520 NICs with latest supported drivers (both compiled and modprobed into the kernel).
lspci -v | grep -i eth
3b:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)
Subsystem: Cisco Systems Inc Ethernet Controller 10G X550T
3b:00.1 Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)
Subsystem: Cisco Systems Inc Ethernet Controller 10G X550T
5e:00.0 Ethernet controller: Mellanox Technologies MT26448 [ConnectX EN 10GigE, PCIe 2.0 5GT/s] (rev b0)
d8:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
Subsystem: Intel Corporation Ethernet Server Adapter X520-2
d8:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
Subsystem: Intel Corporation Ethernet Server Adapter X520-2
I maxed out receive rings, queue depths, disabled pause in receive and transmit directions, etc. and as far as I can tell, NICs can receive packets at 1 Gbps rate with no dropped packets. However, running tshark and writing directly into the RAIDed SSDs I get ~0.5% packet loss, irrespective of the packet size distribution (fixed versus variable, what size packets are used, etc.).
It seems like there are a lot of processes in kernel that get capped even at 1 Gbps rate (likely, related with packet analysis). I was hoping there might be a way to either disable all the unnecessary gunk within the kernel, stripping it down to bare minimum to run packet capture and minimize system overhead in the process. Has anybody done any kernel stripping for this purpose? Are there any distros available that might be better suited for this task than a general purpose Ubuntu server?
Any pointers / thoughts would be really appreciated.
Thanks in advance !!!!

No iP using static DHCP
Hi everyone,
I am using my switch to do the DHCP and give IP addresses. It is set to static, with each device having a MAC address binded to a specific iP.
Now my problem is this... The switch turns on and gives IP addresses to all the computers it finds is connected to the network at the time it is turned on. When I connect my device at a later time, the switch doesn't give it an IP since it already gave out IP earlier. It isnt like in dynamic DHCP setting where the DHCP server is always on the lookout for a new discoverable device. It seems that in static, it just gives the IPs once and that's it. Since my computer wasn't on at the time the IPs were issued, mine didnt get an IP even if I connect to the network later on. The solution so far is to reset the switch so that it will go and give out IPs again, but this of course is quite a hassle.
So here are my questions:
Will this also happen if I use ubuntu as my DHCP server still set at static?
What can I do to make it operate like a dynamic DHCP, but still have the security of a static IP with MAC binding?
I was thinking one of the things I could do was simply MAC bind all the IP addresses I need and then MAC bind the unused ones to "fake" MAC Addresses then set the system to dynamic DHCP. In this way, when a device we haven't registered yet becomes discoverable network, the DHCP cant give it any addresses because all its addresses have already been reserved.
Our IP addresses have already been mapped out: e.g. all computers are at 1-100, all mobile phone at 101-120, printers are 120-150, etc. So in this way, I can't simply reduce the range.
What do you guys think? What other solutions do we have? Now, my switch only handles up to 65 reserved IP addresses, so I might need to really switch to an ubuntu machine.

Ubuntu 18.04 - Toshiba AR9462 issues
Hi all,
New to Ubuntu, and linux as a whole, so i'll need baby steps and some spoon feeding. Sorry in advance! :)
I recently swapped the OS on my old Toshiba Sat Pro C70-A-17L to Ubuntu 18.04, as a test platform for learning my way in to this world.
The install seems to have gone fine and everything seemed okay, until i unplugged the Ethernet cable and apparently the WiFi card doesn't want to play.
I did a little google-foo and rfkill shows the wlan hard-blocked, but I can confirm the fn+f12 switch is on, and the laptop shows a little orange light for the wifi.
(if i fn+f12 again the light goes out, and the item disappears from the rfkill list)
The wifi in these models should be the qualcomm atheros ar9462 - is this supported in the linux world?
Thanks for any help in advance, i'll keep searching the forums too.
Regards,
Martin 'Mouse'
