I am unable to share a folders to other windows users in Mac. It worked afternoon so install then rebooted and folders do not appear. I've tried to set up SAMBA. As this is going to be my Plex server. I have a 3 TB hard drive that I need to empty with TV shows on it. When I tried to copy the files off my three terabyte hard drive the computer freezes. I also have an array card there's several years old. Any help would be appreciated. I am a Windows and Mac user. I can list hardware specs if needed. I'm using kbuntu os.

Set up a PTZ camera on my Network.

I hope this is the place to ask this question? I purchased a PTZ camera and want to have it on my network. I was able to get the setting off the camera. The IP address is 192.168.100.84. My network router is 192.168.1.1. I need to change the IP on the camera to 192.168.1.84.
My question is in a couple of parts. First, do I need to connect the camera directly to the laptop using a cross-over-cable? If I connect it to my router I can not see it.
Next, if I use a cross-over-cable how can I change the IP address? Do I do it in a browser window or at the command prompt? And how do I do it?
There have Windows and Mac software to do this, but nothing for Linux.
This is the camera I am trying to set up. https://www.bhphotovideo.com/c/produ...ferencing.html

Airplane mode and bluetooth suspend buttons linked in OS

Sorry if this is the wrong sub for this, but I wasn't fully sure where to post. I have been trying to disable the "Bluetooth can be turned off to save power" option in System>Power, but whenever i disable it, airplane mode engages. This cannot be correct. I have searched this site and maybe my search terms are not creative enough. Anyone else dealt with this?

I am on a HP Elitebook 850 G3, if that is helpful. This issue is only an annoyance, but still...

Thanks in advance,
Guy

[ubuntu] IP Tables Blocking a particular subnet

Dear All,

I want to access machine from a particular sub-net (say 10.0.0.0/24 to 10.2.0.1/24) . I am able to access all other machines in that particular sub-net except this Ubuntu machine.
I disabled UFW and checked but no luck !

How I can overcome this issue by modifying the IPTables ;current IPTables as following. Is anything restricting here since am not an expert in IPTables.

#iptables -L

i recently converted a windows 7 laptop to Ubuntu 20. and cannot get the usb wifi adapter to work.It is showing up when searched. i have the drivers in my download folder since it came on a cd.

i have no real knowledge of how to write the commands for getting the drivers installed from the download folder. As a Windows user, i'm use to just running the install program from the cd. this is not the way it's done with Linux, i know. it would be nice if there were an app that could locate the drivers on the cd, then extract them to the system.

if there is an app, could someone direct me to it? if there is no app, what is the best way for me to get the drives installed?. i have been reading up on the basics so far, and would like to continue learning how it woks. until then, help getting my wifi adapter would be appreciated.

thanks

20.04 NetworkManager How to autoconnect to specific hidden Wi-Fi network?

$
0
0
In Xubuntu 18.04, NetworkManager would automatically connect to hidden-SSID Wi-Fi networks by default. I didn't like that being default behavior, but sometimes for a specific hidden Wi-Fi network it can be helpful.

In Xubuntu 20.04, NetworkManager does not automatically connect to hidden Wi-Fi network by default :) But even when "Connect automatically with priority" is checked, it still doesn't automatically connect? I must manually go to NetworkManager > "Connect to Hidden Wi-Fi Network...", then select the Wi-Fi network from the drop-down and click Connect.

How to enable automatic connection to a specific hidden-SSID Wi-Fi network?

[lubuntu] Install of 20.04 disables WiFi

$

I have an HP Paviliion TS11 running Lubuntu 18.04, with a dongle for WiFi access (I couldn't get the built-in RT3290 to work). A couple of years ago, a kernel upgrade disabled WiFi, but I was given assistance in https://ubuntuforums.org/showthread.php?t=2398249 by Jeremy31.

I have now arranged for this machine to boot Lubuntu 20.04 alongside 18.04, with kernels 4.5.0-106 and 5.4.0-26 respectively. The 18.04 system works fine, but not the 20.04 system (I tried downloading the software from the same address as before, https://github.com/abperiasamy/rtl88...21AU_linux.git, but presumably this isn't suitable for a 5.4 kernel).

I wonder if software for the series 5 kernels is available?

Thanks.

[SOLVED] Share Ubuntu printer to windows clients using SAMBA

$

Hi,

I am trying to make printers connected to my Ubuntu 20.04 machine available to windows clients of several flavours - 2000, XP, 7 & 10. I'd also like to be able to browse for SMB shares on the ubuntu host from those clients ( I can connect to the shares by explicitly entering their details). I thought I'd done everything necessary - here are the relevant parts of smb.conf:

Code:

workgroup = WORKGROUP netbios name = namrok-i7 security = user proxy
  server min protocol = NT1

Code:

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
  interfaces = 127.0.0.0/8 eno1

Note: I had to change eth0 to eno1 in the line above to match the output of ifconfig, before nmdb would start cleanly.

Code:

printers]
  comment = All Printers
  browseable = yes
  path = /var/spool/samba
  printable = yes
  guest ok = yes
;  use client driver = Yes
;  read only = yes
  create mask = 0700

# Windows clients look for this share name as a source of downloadable
# printer drivers
[print$]
  comment = Printer Drivers
  path = /var/lib/samba/printers
  browseable = yes
  read only = no
  guest ok = yes

I'm sure it's something simple I'm missing (it usually is!).

Thanks for any and all help.

Broke Entire Networking on Wireguard Uninstall

I really need your urgent help. I've broken my entire 18.04 Server when I removed Wireguard hoping to get it working again. The system cannot raise its networking service anymore.

On boot, "Raise networking interfaces" fails. "ifconfig -s -a"only shows the lo, not my enp4s0 that used to be my ethernet. "ifup -v enp4s0"reports "cannot find device enp4s0"

/etc/network/interfaces shows:
auto lo
iface lo inet loopback
auto enp4s0
iface enp4s0 inet dhcp

I'm at a loss as to how to troubleshoot this, and it has brought my entire network down because the server handles my DHCP.

Please help. I really appreciate it.

Edit: In digging around, I suspect that I need to know how to load the driver for my ethernet port. My ethernet comes in off an RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (i.e. my motherboard; that's the lspci output). Running lshw -C network results in "Network: UNCLAIMED".

How do I load the drivers for that controller?

[ubuntu] Cannot access files on PVR after last samba update

:( Hi, Have an old Divco PVR that runs on linux, it is connected to modem/router by LAN, have been able to access files and folders on it from my desktop ubuntu (20.04) machine for years. But Samba up dated just recently Ubuntu machine can see PVR, see HDD, but when double clicked on comes back with dialog box "Unable to access location" "Failed to mount Windows Share: Software caused connection abort"
Ubuntu can see and swap files with windows laptop and laptop can see and download files from PVR
The PVR uses Samba as well, and as it is old and no longer supported there is no chance of an up date at that end.
Can i add something to smb.conf to allow it to continue to read the HDD on PVR.
Thank you

[SOLVED] Cannot find working driver for Techkey WiFi Adapter(600mbps)

I've had a Techkey WiFi Adapter for a while and have used it on Windows 10 and 7, and it has worked so far.
I recently installed Ubuntu Desktop 18.04 LTS, my knowledge of Linux is rudimentary and I only know the basics such as installing packages, finding my kernel version, and moving and copying files from the terminal. My WiFi Adapter is only recognized as "Realtek Driver Storage" in Ubuntu and my attempts at finding a working driver have been unsuccessful.

Potentially Useful Information:

uname -r Output:
Code:

5.3.0-59-generic
When running lsusb, the device shows as:

Raspberry PI 4. Ubuntu can't see 5ghz wifi

My localization is set correctly, but for some reason I can't see 5ghz networks. I'm a n00b with Ubuntu, but I'm fairly confident I can provide you what you need. All apps updated via sudo apt update && sudo apt upgrade. I have no idea why this is. With raspbian I can connect to 5ghz, no problem. It's a Raspberry Pi 4gb, with ubuntu core 20 installed. I hate 2.4ghz, please help!!

WiFi disconnects with AC 9560 adapter running 20.04

Hi!

Recently got a MSI GF63 laptop with an AC 9560 card and the wifi disconnects frequently. I've tried switching from 5ghz to 2.4ghz, changing channels it's on, and checking drivers. Not sure what I'm missing and I'm out of ideas.

I ran the wireless info script and the output is here: https://pastebin.com/QnYsQVFN

Let me know if I can provide any other info.

Intel AX200 worked fine on initial install of 20.04, on re-install doesnt work

$

Hi, I am looking at what is (to me) a fairly perplexing situation.

I installed ubuntu on an extra Nvme SSD on a razer blade 17" early 2019. This uses the Intel AX200 wifi chip. One nvme slot has the original windows SSD, I added another one and installed ubuntu 20.04 with almost-full disk encryption as described here:

https://help.ubuntu.com/community/Fu...ion_Howto_2019

secure boot is off

Everything worked out of the box, except a minor hibernation glitch which I fixed by doing this:

https://danmackinlay.name/notebook/comfy_razer.html
Quote:

Keeps on suspending again after suspending once

After the laptop has gone to sleep one time it has narcolepsy and keeps sleeping again?
I found this fix somewhere: append button.lid_init_state=open to the value of GRUB_CMDLINE_LINUX_DEFAULT="" in /etc/default/grub then
update-grub
Anyway with this initial install, secure boot was off, I chose normal install rather than minimal, and requested third party drivers. Wifi worked fine!!

Based on this initial positive experience I decided to get a larger Nvme drive and make a serious linux machine out of this laptop. I backed up my data, swapped out the linux nvme for a new one, and re-installed everything the same way. Even using the exact same installer USB.

Except this time, wifi doesnt work! When I boot into windows it does work. Having done everything the exact same way, I'm confused how I got two different outcomes.

Code:

$ dmesg | grep iwlwifi
[    9.449778] iwlwifi 0000:3f:00.0: enabling device (0000 -> 0002)
[    9.839374] iwlwifi: probe of 0000:3f:00.0 failed with error -110
$ lspci -nnk | grep 0280 -A3

    Subsystem: Intel Corporation Wi-Fi 6 AX200 [8086:0084]
    Kernel modules: iwlwifi

I tried installing both the backports driver as well as the iwlwifi-cc-a0-46.ucode driver which I downloaded from Intel

INDEX


1. OVERVIEW
2. INSTALLATION
3. LICENSE




1. OVERVIEW


The file iwlwifi-cc-a0-46.ucode provided in this package must be present on
your system in order for the Intel Wireless WiFi Link AGN driver for Linux
(iwlwifi) to operate on your system.


The "-46" in the filename reflects an interface/architecture version number.
It will change only when changes in new uCode releases make the new uCode
incompatible with earlier drivers.
Code:

$sudo cp -v -u '/home/user/Desktop/linux/iwlwifi-cc-46.3cfab8da.0/iwlwifi-cc-a0-46.ucode' /lib/firmware
$sudo update-initramfs -uk all
$reboot

but after trying both of those drivers, and rebooting, I am still getting the "wi-fi device not detected" error.

It is the 20.04 ubuntu install from the ISO installer file, but for reference kernel is Linux 5.4.0-37-generic

I am up and running with LAN cable/wired internet now, but obviously really would like to get the wifi working again.

I also tried installing openrazer-meta which didn't help. I did all software updates offered in the manager, sudo apt update, sudo apt upgrade, etc.

Any ideas? I am perplexed in particular because the first install went off without a hitch and wifi was working without my having to do anything about it, and now I cant get it to work, I cannot think of what I did differently this time

Thanks!

Hello! I tried to follow the instructions in the stickied post titled "How to install a driver for the broadcom series of PCI wireless cards" and ran into some difficulties,

When I type #sudo apt-get install bcmwl-kernel-source

It says #E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 2296 (apt)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?


Would anyone be able to help me? I am currently using my phone as a personal hotspot for internet but that won't be too sustainable.

Hey guys, sorry I feel like this question is super simple but I JUST installed Ubuntu from a USB and did not see any way to connect to the internet in the hotbar. When I went in the network setting the only ones available were just to setup a VPN, I can't find any wireless connections, and I do not own an ethernet cable to try a wired connection.

I tried searching the internet for help, but all of it was outdated, and did not work for me.

Thank you so much for the help!
