Debian Configuration :: Wake On Lan Settings Don't Stick?
Feb 11, 2010
I recently switched back to Debian after getting fed up with Ubuntu. The one feature that I haven't been able to get back since the switch is Wake on LAN.If I turn on the computer and watch tcpdump, I can see the packets hitting my machine. I don't think it's a router configuration issue.If I shut down from windows, WOL works.Another sign that it's not a networking or BIOS thing.Here's some stuff I've tried:When I boot up in linux, if I run ethtool eth0, it tells me that wake is set to g (which every guide I've read says is correct).Just in case, I added "post-up /usr/sbin/ethtool -s $IFACE wol g" to /etc/network/interfaces (as shown here: ewtopic.php?f=5&t=42049&p=244736&hilit=wakeonlan#p244736). Also added same thing for post-down.
In /etc/init.d/halt, I changed NETDOWN to no (also from previous guide) to keep my eth card from being shut down.Also changed /etc/init.d/networking to exclude eth0 (as documented in Added "pre-down false" to /etc/network/interfaces.. trepid+wol), to keep eth0 from being shut off.Anyway, I'm guessing that either there's another script somewhere shutting off eth0 or I'm completely wrong in assuming that's the problem. I've been googling this problem for a couple weeks now and I'm totally out of ideas.

I'm am able to WOL my computer when it has been halted (or shutdown, which is basically the same thing for the problem I'm facing). The problem comes when I try to WOL the computer when it is suspended or hibernated. Then, it does not work.
I've been investigating for a while and have found that when halting, the following is done in the /etc/init.d/halt script:

But I don't know which script must be modified in case I want the network not to be brought down when the computer is suspended or hibernated.

Suspend worked before I completely reinstalled Testing from scratch. Now it seems to suspend OK, but when it tries to wake up it fails. Details here: [URL]

My usb stick with Debian only loads from the usb hub it's crazy. I just tried putting the usb stick onto a usb3 port in my desktop and also on a usb2 port even the one where the usb hub is connected to and it wont' load!. Same initramfs prompt happens as when connected on the laptop usb ports.
the usb hub has usb2 speeds so is not that the stick is under usb1.1 emulation.

This is a perennial problem with Linux. I am just not comfortable moving a lot of casual files around as root. How can I have user access to a USB stick? I've done my Google searches and tried several methods, some of which work temporarily but not permanently. At the moment, I have this line in my /etc/fstab: /dev/sdd /media/usb_flash ntfs noauto,users,rw,umask=0 0 0
As with other methods, this worked last week but not now.
All I want to do is insert a USB stick, transfer some files and remove the stick. I want to do this as a user. This should be simple. What is the trick?

I have a USB stick, formatted as FAT32 and I assumed that everybody would be able to read from and write to it. However, I find that if more than one person is logged on to the machine (logged on locally, with "Switch User"), then only one of the users is allowed to write to the stick, and the other users are only allowed to read from it. Is that normal?
Here's the scenario: person A logs into the machine, is in the middle of something but gets called away and the screensaver kicks in. The screen is now locked. Person B comes to the machine to quickly copy a file onto a USB stick, doesn't know person A's password so does a "Switch User" and logs in as themselves. They plug in the stick, can read from it, but can't write to the stick at all. Permission denied.
By doing a "ls -l /media", person B can see that the stick is mounted but is owned by personA with permissions drwxr-xr-x . So only person A can write to the stick. I haven't done extensive testing but it seems to be the person who logged on first who gets to own the stick. It's certainly repeatable as described above. And it's really annoying, because unless person B knows the root password, he can't write to the stick. As a real last resort person B could reboot the computer but he doesn't know whether person A has any important stuff open or not.

Im trying to remote power on my debian machine with gnome with the wake on lan function. I enabled it on my mainboard and was configuring my ethtool. There i see:
root@lappy:~# ethtool eth0
Settings for eth0:
Supports Wake-on: g
Wake-on: d
Link detected: yes
and after this command ethtool -s eth0 wol g i get this:
root@lappy:~# ethtool eth0
Settings for eth0:
Supports Wake-on: g
Wake-on: g
Link detected: yes
So i enabled it on software and hardware. Now im trying to sent the magic packets with a windows tool "wake on lan" I see that the package has been sent but the pc wont turn on. So when i check the ethtool settings again i see that it turned to:
Wake-on: d

if you try to browse the web from the machine, or log in through a nomachine (nxclient/nxserver) session, it claims there is no internet conenction. You have to run System|Administration|Network and select the stored "Location" for our wired connection. There does not seem to be an option to make this (one and only) "Location" the default. If the machine is up and incoming connections are possible (samba & apache), surely outgoing connections should be working without extra fiddling?
The issue with nxserver (nomachine) becoming unavailable on a re-booted unattended machine (unless someone logs in AT THE MACHINE and runs System|Administration|Network) is causing problems for remote access.

My system goes through slow periods where it just crawls and others where it's fine, but I'm wondering which service settings are OK to just shut off to give me a bit more oomph when I boot up.The others I'm pretty OK with like spam assassin, dictionary server and so on, but some of the others i wonder if they only serve to slow things down..Also..I live in a very dusty environment and I KNOW the fans and other parts get caked with dust and it wouldn't surprise me if the dust got so bad it just stops the fans completely so once in a while I use my air compressor to blow the crud out and I usually get covered myself, but how safe is using the compressor? It's not the type that typically fills up with condensed water droplets so that isn't a super critical issue..It's a small 1 hp deal, elect drive and so on.. Safe enough? It's all I have and/or can afford..

I need to set up a little virtual network with Debian Lenny guests (the host is Debian Squeeze, but I don't think it matters). I installed Lenny in a VM and it works fine. Then I cloned the hard drive, garion@Laptop:~$ VBoxManage clonevdi Linux 1.vdi Linux 2.vdi created a new VM with exactly the same settings as the first one and booted the new disc. The problem is that there's no eth0 in the new VM, but it is in the original one. Also if I "unplug" the cable, dmesg won't notice anything. In the original VM it works fine. They both have the same virtual network card: PCnet-FAST III (Am79C973). I've also tried NAT as well as internal network settings.

I've always used Debian with a single monitor and no need of proprietary drivers, because I usually don't do graphics or multimedia. Now I'm asked to set-up a machine with 3 nvidia video cards (770) and 4 monitors and everything went south. I started with just 2 monitors connected to 2 different video cards, not wanting to push my luck.
I installed a fresh Jessie and followed the instruction to install the nvidia drivers and tools from the Wiki. Everything went smooth. After reboot I executed (as root) nvidia-settings and I configured the two monitors to be one to the right to the other, with BaseMosaic option (at this point just one monitor was active) I saved the configuration to /etc/X11/xorg.conf , I even executed nvidia-xconfig as suggested, I rebooted and nothing happened, only one monitor was working, while the other -- looking again in the nvidia settings -- was still disabled.
I then tried with xinerama option and things are even worse, since now both monitors are black. I can login in one textual shell, but then I don't know what to do, since in my 10+ years of linux ... I never had to mess with X server. Is there a way to at least recover a working X without reinstalling everything?

I am currently using Debian Lenny and am having problems with my pptp vpn client. I can use the following software for as long as I like without my pptp vpn connection dropping out:
(1) iceweasel
(2) icedove
(3) gtk-gnutella
If a use a bittorrent client, however, my pptp vpn connection drops out within a few minutes. I have tried these bittorrent clients: transmission, deluge, tixati. Enabling or disabling the firewall makes no difference.I have searched pptpclient.sourceforge.net and Debian User Forums but have not been able to find any suggestions on settings to change in a bittorrent client.

I'm running openSUSE 11.3 64 bit KDE 4 standardI have two monitors attached, running simultaneously, nicely, all is well.But when I reboot I have to set them up again because the settings don't stick/endure through a reboot.The GUI configurator that I use is at Menu --> Config Desktop --> General --> Display.How do I save the underlying settings and re-invoke them at boot time, perhaps from the CLI? Or some quick process that will do the job.

I have no clue why KDE is doing this, but whenever I reboot the system, the resolution resets to 1024x768. I really need to stop it from doing this. Also, Sax2 doesn't seem to be working and there is no xorg.conf file that I can see of.

I've been trying without success for the past couple of weeks to setup a filtering system for my little sister's netbook. The main problem I've been running into is inconsistency. First, I tried using dyndns per the instructions here: [URL] The problem with this is the DNS settings (and in turn the filtering settings) dont appear to 'stick' once the Netbook touches a different network. So if I sign onto a different wireless network than the one I used to set up the filtering, it stops working. The reason why is Ubuntu will overwrite the current DNS settings with those of the new network (I have no idea why, and am too frustrated to figure out).
Also, I noticed that even if the settings did stick, they're fairly easy to disable because all she has to do is stumble across the DNS settings, change them back and voila. I've had great success with OpenDNS on Windows boxes, but there doesn't seem a to be a feasible way to apply it to Ubuntu. Dansguardian looks like it may be worth a shot, but I've seen dozens of "simple" configuration guides, none of which that actually looked simple. So my question is this, what is the easiest, most bulletproof way to setup web filtering 10.4? Preferably something that a 12 year-old could easier find her way around.

I am using Centos 5. I got one error unexpectedly after some configuration for rsync and folder settings. The error i am getting is "Serve Authorization directory (daemon/ServAuthDir) is set to /var/gdm but does not exist. Please correct the configuration and restart GDM." after rebooting.
I tried to resolve the issue by setting permission for folder /var/gdm to 755. but the problem is still not resolved.

I am hosting a home server to make developing stuff easier. And because I don't need my server all day and night I automatically start and shut it down. For starting I use Wake-On-Lan (etherwake) and to shut it down I am using my RaspberryPi. Finally I have a problem doing that: When I use WOL to start my home server it works perfect. But when I try to shut it down, I have to do that twice. After the first shutdown it restarts automatically even when no WOL-Package is sent.
I am using Debian 8.1 Mate as os.
My stop script is:
Code: Select allsshpass -p<password> ssh root@server.home.lan shutdown -h now
and I start it with
Code: Select allsudo etherwake <mac address>
both times using a cron job on my RPi.

I have installed Debian 8.1 with KDE desktop on Lenovo t431s with intel HD4000 graphics.
When using it with dual monitor configuration, I experience the problem when I put system to sleep (by closing the lid), then remove the external monitor cable (from miniDP port) and then try to wake system from sleep. The login screen freezes and I am unable to move the mouse or type in credentials. In case I had music player running I can hear the music after system wake , but it shutters while playing.
This does not happen on some other distributions, but the problem is that I very much like my current setup and I would like to fix this problem and keep it.
I do not know if this problem is due to KDE or KDM or it's Debian base.

I came back to debian after trying many others because it installed flawlessly and worked. I'm on the testing channel and upgrade nearly everyday and after a recent upgrade my xsession (Xfce4) display won't wake up any more after I close and re-open the lid. I know the box is awake because I can go to a ctr-alt-fn console login and use it normally. How can I track this down? And is there some way I can restart the gui display from the console without losing what was running before I shut the lid? Right now the only way I can recover is to restart the computer.

I have installed Debian Jessie (<-- brilliant OS ) on my uncles Laptop (it is a Thinkpad E540) with Cinnamon as desktop environment. The installation was no problem. Everything apart from one minor thing works nicely. The minor thing however is the following:
I don't know what it is, but when I don't use a particular usb port for a while and then try to plug in a usb stick or a wacom tablet, it doesn't get recognized, it doesn't show up when I use f.e. Code: Select alllsusb. When I close the lid of the laptop and open it again, then the particular usb device gets recognized and cinnamon asks me what to do, f.e. open a folder and show the content of the usb stick I have plugged in. Because of the success on two other laptops I use the following
Code: Select all# /etc/systemd/system/powertop.service
[Unit]
Description=Powertop tunings
[Service]
Type=oneshot
RemainAfterExit=no
ExecStart=/usr/sbin/powertop --auto-tune
Environment="TERM=xterm"
[Install]
WantedBy=multi-user.target
to save power on the Thinkpad (this is in no way my service script, I tuned everything using powertop in the terminal after having had logged in, the script above stems from a brilliant user here on the forum). Could it therefore be autosuspend that is not working properly here?

I use my laptop connected to an external monitor, so I would like it to wake up from suspend with a wireless keyboard. I could manage to do it when the lid is open, however, when the laptop lid is closed, it doesn't. So I need to open laptop lid each time and it is annoying.
This is how I make it wake up with wireless keyboard:
# echo enabled > /sys/bus/usb/devices/1-2/power/wakeup
I'm using debian jessie. How to make it work when lid is closed?

Is there a config file to toggle whether the screen is locked after hibernation? I looked all over preferences but if it's there, I missed it. In Ubuntu, the screen was always locked after waking up. In Squeeze, it's going directly to desktop. It's not a biggie but you never know when someone might try to access your account so I kind of liked that it would wake up locked. Maybe it's doing that because I'm the only user on the system?
