Hi guys, i am having a bit of a nightmare with this one and i have been pulling my hair out for nearly two weeks trying to fix this issue and finally i decided to ask for help from this great community. I have a standard Linux Mint installed on my laptop and everything is updated. The problem that i am having is that there is a loud static noise coming from my speakers whenever my laptop is on battery power. I get no static at all when my laptop in connected to AC power which leads me to believe it is a power saving issue of some kind but not sure. I have tlp power saver installed and tweaking the settings does little good. On battery power though sometimes the static is a bit quieter to the point of stopping completely. So i think great my issue is solved, only for me to load media like vlc or clementine etc and i get the loud audio static again and when i close these windows it all goes quiet again. There is also the loud static type sound when powering on and off my laptop. I am completely stuck. Please i really really hope someone can help

Hi all, I'm trying to spoof dns in a static network based on the original script. So far, I've spent hours on it without any results - and I don't know why... From my understanding, I would have to do it as such: Let's say I have a network in 192.168.1.0/24 with one router in 192.168.1.1 and my host is 192.168.1.50. 1) set a static IP on eth0 which mimics the router (example: 192.168.1.1) --> uci set network.lan.ipaddr="192.168.1.1" 2) set a static IP on eth1 which mimics my host on the network (example: 192.168.1.50) --> uci set network.wan.ipaddr="192.168.1.50" And then let the script do it's own stuff with the dnsmasq address and the iptables. The whole script would look like this: #!/bin/bash function setup(){ uci set network.lan.ipaddr="192.168.1.1" uci set network.wan.ipaddr="192.168.1.50" sleep 5 cp $(dirname ${BASH_SOURCE[0]})/spoofhost /tmp/dnsmasq.address &> /dev/null /etc/init.d/dnsmasq restart } function run(){ iptables -A PREROUTING -t nat -i eth0 -p udp --dport 53 -j REDIRECT --to-port 53 } setup run

Hi, Lanturtle works fine. Static IP was set, same settings as the direct LAN port on PC (DHCP addresses go through proxy....) Strange thing is, when LAN cable is directly connected I can ping. When LAN cable is attached to the Lanturtle, I can't ping. But I have network, (I can Google, I have connection to SSHFS folder, etc......) Also external DNS's are resolved, internals not. Any ideas?

Hi all! I'm at a loss, so collaboration time! SO: At my work , I have 5 elevators with digital reader boards in them (for the days events and some adverts) that auto-updates from an internal system. Through our internal system, we enter in "Bob Group" and say what meeting room they have and times. Then when we say "Post", that is (theoretically) supposed to send out to these Readerboards to be displayed at the appropriate day. The problem is: Only 2 of the 5 Function like this. Here's the fun part (Are you ready?): - Inside the elevator the PC is on an Eth line. - If I plug in my laptop to snif the other end , I get no link at all. Even the ISP can't find the MAC on the network. Even on the ones that are (theoretically) working. - The main "Player Controller PC" (handles how the reader board will display adverts, etc) is connected to a switch (and our ISP can see that). - At the top of the elevators (Where the pully engines are) , There are 5 wires on a troth going outbound.. Somewhere.. But there's actually 10: 5 blue and 5 White CAT5e. - Down the hall of the Elevator Control room, there's a mini-IDF room that has a wall- mounted cabinet with 5 Cat5e lines LABELED " Elevator 5, Elevator 6, Etc." - When I plug my laptop into that , Nothing. Not even Wireshark can find it. - I can't even find anything on a WiFi Sniff too. No beacon frames match the Elevator PCs at all. ...Is there something i'm missing, or is this a needle in a hay stack?
