[ubuntu] Prevent USB device from power drainage

The battery life on my Acer Aspire E15 E5-575 has gotten seriously bad lately. Using powertop, I've noticed that there seems to be some sort of USB device drawing quite a bit of power.
Code:
Power est.    Usage    Device name
  9.14 W    100.0%        USB device: usb-device-04ca-3015
              0.0 pkts/s  Network interface: eth0 (r8169)
  534 mW    12.5%        DRAM
  304 mW    12.5%        CPU core
 15.0 mW    12.5%        CPU misc
              6.2 pkts/s  Network interface: wlp3s0 (ath10k_pci)
    0 mW    100.0%        USB device: xHCI Host Controller
    0 mW    15.1%        Display backlight
    0 mW      0.0%        USB device: xHCI Host Controller
    0 mW      0.0 ops/s  GPU core
    0 mW      0.0%        Radio device: acer-wmi
    0 mW      0.0%        USB device: HD WebCam (KS0HD0500471803443LM06)
    0 mW      0.0%        Audio codec hwC0D0: Realtek
    0 mW      0.0%        Radio device: btusb
    0 mW      0.0 ops/s  GPU misc
Further research led me to run lsusb -v which shows the following output for usb-device-04ca-3015 :
Bus 001 Device 002: ID 04ca:3015 Lite-On Technology Corp.
Couldn't open device, some information will be missing

I've been searching and messing around with powertop, tlp, and general power settings for a few days now and just can't seem to get rid of this ridiculous power drainage from a usb device. All of the tunables are set to 'Good'. I have also enabled USB autosuspend mode for the Bluetooth device using TLP's configuration.

[ubuntu] TCP and UDP port forwarding problem

October 23, 2017, 11:45 am
$

0
I am trying to ssh into my server when it's VPNed, but it's not working. My VPN provider has set up a port, let's call it 12345, that's supposedly "open" both in TCP and UDP.

I have set up sshd to listen on TCP port 12345, which I've tested by successfully sshing into my machine without the VPN running. I can also ssh normally, using port 22.

But when the VPN is up, all I get is "Connection refused."

I have repeatedly tried to convince the VPN that this is an issue at their side, as my nmap scan of the VPNed system shows the port 12345 UDP as "open" but the TCP as "open|filtered."

They say it's a problem with my firewall, but I don't believe I'm RUNNING a firewall. Isn't ufw disabled from the start?

I'm behind a router, and have opened port 12345 successfully there (or otherwise I couldn't ssh using -p 12345 when I'm NOT using the VPN).

My biggest problem is that I don't have the knowledge to properly understand how to check things. I thought the fact that I can SSH fine without the VPN to port 12345 but when it's up I can't access it would mean that it's a problem with the VPN, but could there be some other problem at my side that's causing errors? Are there IPtable rules I need to modify to allow the port to connect when it's on the VPN?

Any help would be very much appreciated. Thank you!

[xubuntu] Something is rfkilling my WiFi card on boot.

October 24, 2017, 8:18 am

The 17.04 -> 17.10 upgrade broke a few things that I'm stumped on how to fix, so I guess I'm going to post about them one at a time until they're all solved. Hey speaking of which, is it normal to have upgrades break stuff? That's pretty annoying if so. I may have to stick with LTS if I'm going to have to manually fix things for every update. :/

So my system is set up a little bit strangely. I'm using i3 on Xubuntu, and my network manager is wicd instead of NetworkManager.

The problem I've been having is that when I first boot, my WiFi and ethernet are both rfkilled automatically. And I have to go into a terminal and manually un-rfkill them. Hey speaking of which, why does rfkill exist, anyway? Isn't "rfkill block <foo>" a fancier version of "ifconfig <foo> down"? It seems redundant, and the manpage isn't much help.

But anyway, I'm trying to figure out what's doing the rfkilling so I can disable it. I could just have an autorun script to "rfkill unblock" everything for me, but that seems like it'd come back to bite me at some point.

As soon as I "rfkill unblock" everything, it's fine until the computer turns off again. I'm preeeetty sure that logging out and back in again won't trigger another rfkill. I might test that after I'm done with this post.

I looked through the settings on wicd-client and there wasn't anything that seemed helpful there.

Also, I checked just to make sure that NetworkManager isn't installed, and it's not:

Code:
$ sudo apt remove network-manager
Reading package lists... Done
Building dependency tree     
Reading state information... Done
Package 'network-manager' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Here's my wireless-info: https://paste.ubuntu.com/25810049/

I'd really love some pointers on what to try next. Thanks in advance for the help!

Hi everyone. This afternoon my 14.04 laptop lost all internet connection after apt-get dist-upgrade and update. I did some research to try to fix the problem, including downloading and installing three deb packages according to this link:https://ubuntuforums.org/showthread.php?t=2311705 , but the problem seemed built-in. "Network" icon in "Settings" still shows "the system network services are not compatible with this version". Any hint to solve it? Many thanks.

Hello

since upgrade, systemd-resolve takes 100% CPU.

Code:
PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM    TIME+ COMMAND
925 systemd+  20  0  67476  7552  5104 R  98,3  0,1  82:48.57 systemd-resolve
954 dnsmasq  20  0  57440  2840  2420 R  51,2  0,0  38:50.39 dnsmasq
As you see dnsmasq is using a lot of CPU as well. Maybe due to the same root cause?

Here is the config /etc/systemd/resolved.conf

Code:

[ubuntu] using internal and external network interfaces

Hi All,

Just installed Ubuntu 17.10. I have two network interfaces, a. wifi and b. ethernet.

I connect wifi to one router - network 192.168.1.x and ethernet to another network 192.168.0.x. both 192.168.1.x and 192.168.0.x have internet access. I want to make sure when I browse internet, it uses 192.168.1.x and not 192.168.0.x. Basically, I want to use 192.168.1.x for internet access and 192.168.0.x for internal network use only (like connecting my ubuntu box from my laptop etc.)

Can you please suggest how do I achieve this? Sorry if this is a novice network question.

Thanks
Kunal

Hello !

I've.. got a problem :D . I have installed Ubuntu lately (next to my win 10). But i cannoct connect to wifi- I have tried a lots of advices from forums and internet sites, but havent found anything that would work, that is why I'm writing this thread. I also thought, that a network cable could work the problem out but, well, I'm at my student apartement and i won't get home for more than a week.Also i cannot access additional drivers, i also attach screens from the error from additional drivers.

I will be so glad for any idea how to work this out :) !

See you for now.

[ubuntu] 16.04.03 Edimax EQ-7611ULB Supported?

Hi, I put the above card into my computer -- and the Bluetooth is detected, but never finds anything, nor can it be found.

I've checked the usual stuff and it's not blocked and is detected. But this also has wi-fi cababilites and those aren't detected.

My guess is that this card isn't supported, but wanted to check first to see if there's something I missed

Hello.

I have a setup where about 10 computers are networked via LAN to a router.

We have a USB hard drive plugged into the router for realtime sync and backup of documents and files from specific folders on Windows OS

I want to switch some of those computers to Ubuntu, so it is essential that we are able to continue the realtime sync/backup.

How can I do this?

I've been trying to be able to have remote access to my server with the help of OpenVPN.
I followed this guide (yes I know it's for 16.04 but I could not find anything else):
https://www.digitalocean.com/communi...n-ubuntu-16-04

But it didn't work. Is there any specific guide from where I could learn it for my version of Ubuntu Server?

[ubuntu] Since Upgrading to Clean 17.10 no Wifi

Hi,

I had wifi with 17.04, but not after a clean install of Ubuntu 17.10 with all updates and the Intel microcode additional driver installed. I have a Lenovo Ideapad Miix
510-121KB

If I tried:

sudo rm /etc/resolv.conf
sudo ln -s ../run/resolvconf/resolv.conf /etc/resolv.conf
sudo resolvconf -u

After the first two I lose my wired LAN, then for the third it said resolvconf did not exist.

Reinstalled clean 17.10. Installed updates and Intel driver. Installed resolvconf. Ran the three lines above and a restart of NetworkManager and wifi was on, I could see local networks, but I could not connect to mine. Restarted the router and still no connect.

After a reboot, no wifi and it will not turn on. Ran the commands again and it still will not turn on.

I just tried this:

sudo dpkg-reconfigure resolvconf

This worked, in so much as the wifi was on but couldn't connect. Since a power-off, the wifi will not turn on.

I ran the scripts in https://ubuntuforums.org/showthread.php?t=370108 to get the wifi information and the link to the pastebin is below.

Early on in the logs it reports that some items are hard off (I can't make much sense of this a WAN is off and on in two places). The wifi is enabled in BIOS and my aircraft mode button does nothing (and never has). For example, no matter how many times I press it or for how long, my Bluetooth mouse stays connected.

Any additional suggestions?
