Networking :: Ethtool Not Properly Enabling WOL?
Nov 25, 2008
I'm having problems enabling Wake-on-LAN using ethtool.I'm using ethtool 5.1 on Fedora 8. Ethtool reports that the card supports u,m,b,g for WOL modes. I can run "ethtool -s eth0 wol g", which completes without errors.If I run ethtool again, the Wake-on setting is changed to whatever I just set it to. However, when I actually shutdown the machine, the lights on the NIC don't stay on as they normally should, and any attempts to wake the machine have no effect. The machine dual-boot Windows XP, and I have enabled WOL in the driver there. When I shutdown the machine from XP, everything works just fine. The NIC lights remain on and the machine wakes up properly. So...I think I have my BIOS configured properly, and my WOL utility is working properly.
Hardware Info:

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

I have two onboard gigabit connections and a PCI-E gigabit card, none of which seem to want to run beyond 100M. Everytime I issue the command to change speed to 1000M, it does nothing. I have tried modifying the interfaces file to make sure the command line for ethtool gets done automatically, but still no luck.
Below is the output from the use of ethtool to change speed. Since I am having performance issues with my local area networking (e.g. Samba transferring slower than the internet), I have been trying to figure out how to debug my network performance, and this was an obvious thing that stood out. The router and card are gigabit, yet don't use their full transfer rates.

So I have tried looking on the web for a solution to this, but I can't find anything. I have only found 2 posts with the same problem and both went unanswered. So I want to set my ubuntu machine to WOL with both Magic Packet and Unicast (the g and u functions in ethtool wol) wol supported: pumbg (thus g and u are both supported) I use "sudo ethtool -s eth0 wol ug" and check to see if it changed, and it does
sudo ethtool eth0
"wol: ug"
After I suspend though, only magic packet will wake it up! I go back in and check with "sudo ethtool eth0" and low and behold, it is back to only being "wol g", which is the default. For some reason it must bump back to default before going into suspend. NOTE, this is with suspend, not even a reboot or a shutdown! Even suspend will reset it to default. I have worked on adding a script to /etc/init.d, adding lines to /etc/rc.local, and adding lines to /etc/networking/interfaces, all with no change.
Any idea what is going on and why it is resetting wol back to default?? I know I should be happy at LEAST it does magic packet, but I want to know why it wont change.

I just started learning network on linux platform. Today I came across two commands ethtool and miitool. Both of them seems to do similar kind of jobs. Now I am confused what is the difference between them.

I am running a test to determine when packet drops occur. I'm using a Spirent TestCenter through a switch (necessary to aggregate Ethernet traffic from 5 ports to one optical link) to a server using a Myricom card.While running my test, if the input rate is below a certain value, ethtool does not report any drop (except dropped_multicast_filtered which is incrementing at a very slow rate). However, tcpdump reports X number of packets "dropped by kernel". Then if I increase the input rate, ethtool reports drops but "ifconfig eth2" does not. In fact, ifconfig doesn't seem to report any packet drops at all. Do they all measure packet drops at different "levels", i.e. ethtool at the NIC level, tcpdump at the kernel level etc?nd am I right to say that in the journey of an incoming packet, the NIC level is the "so-called" first level, then the kernel, then the user application? So any packet drop is likely to happen first at the NIC, then the kernel, then the user application? So if there is no packet drop at the NIC, but packet drop at the kernel, then the bottleneck is not at the NIC?

I have a CentOS 5.5 machine (hosted at a remote hosting company) where "ethtool" reports that the eth0 device is currently in 10 Mbps mode, but the output indicates that it supports 100 Mbps. But if I try using ethtool to switch the device into 100 Mbps mode, it doesn't work; after running the command to switch it to 100 Mbps, ethtool reports the speed is still 10 Mbps:
[root@sls-eb5p17 network-scripts]# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
[Code]...
The man page at [URL]..ethtool seems to suggest that this should have worked. Any reason why the reported speed of the device didn't change? Changing other settings doesn't appear to work either, e.g. if I specify "duplex half" instead of "speed 100", eth0 still reports "Duplex: Full".

when I tried to configure network I came across a problem that the enable button on top of network manager GUI is disabled. So alternatively I enabled it with ifconfig command. I also configured DNS servers. But the problem is whenever I reboot my machine. I have to reactivate the network from terminal and give the DNS servers again, because DNS settings are not saved.

I've been having an issue for the last day or so. I have an HP Pavilion dv8000 running 10.10. Whenever I boot with the Wireless activated, it will lock about 3-4 seconds into the log-in screen (I'm guessing when it connects to my router). If I have the wireless deactivated (like now), I am able to use the ethernet connection, or (like now) use my phone to tether internet. But, as soon as I click the wireless to active, locks up. The wireless activity light flashes, but that's all.
I'm pretty good about updating whenever I use my laptop, but I think something in the most recent update may have broken my wireless connection.

I am trying to set my gigabit NIC to 1000 MB setting using ethtool. The only way I can get it to register that way is to turn off auto negotiation and that just kills my signal. Below is the output of the current settings and the commands I have attempted with zero success.

trying to bring back to useful ife an old laptop: an Acer 1360.
I have installed kmod-ndiswrapper to assist me. The laptop has one of these:
Quote:
00:0a.0 Ethernet controller: Linksys, A Division of Cisco Systems [AirConn] INPROCOMM IPN 2220 Wireless LAN Adapter (rev 01)
I have grabbed the Windows drivers for this card and installed:
Quote:
[graham@old-acer ~]$ ndiswrapper -l
WARNING: All config files need .conf: /etc/modprobe.d/ndiswrapper, it will be ignored in a future release.
neti2220 : driver installed
device (17FE:2220) present
lsmod shows:
Quote:
ndiswrapper 158060 0
Looking good to me - (is that conf file required an issue?) but Network Manager doesn't recognise that I have any wlan running at all. The Wifi button on the laptop is on but 'red' and not 'green' for up and running.
Um. Next steps? I suppose I could buy a compatible wifi card and slap it in?

I've got a BCM 4312 card on a Dell laptop running 10.04 and an Apple Airport network. Since I configured the Airport to use "WPA2 Personal" Authentication, my connection is flaky: it drops for no apparent reason and sometimes I can't connect at all. When authentication is turned off, the connection is rock solid.
Here's an example from the syslog of a failed attempt to connect:
Code:
Oct 26 19:31:24 firefly NetworkManager: <info> Activation (eth1) starting connection 'Auto Rittenhouse'
Oct 26 19:31:24 firefly NetworkManager: <info> (eth1): device state change: 3 -> 4 (reason 0)

I ran into this today accidentally turned on networkmanager and it took it upon itself to rewrite some things and proceeded to make any DNS lookups on my server Especially those reverse DNS for SSH and SFTP take so long they would just time out instead of completing.. Disabling networkmanager did not undo the damage either. Short fix, Erase your resolv.conf file and add 2 lines to it as so, your nameservers!
nameserver xxx.xxx.xxx.xxx
nameserver yyy.yyy.yyy.yyy
save, and run the following commands
service network restart
service httpd restart
service sshd restart
Mine had a search line added by networkmanager and some others, when i reverted it back to as above, almost instantly after restarting the services the systems lookups were once again, lightning fast. DNS lookups were taking upwards of 20 seconds for unknown reasons after this happenned

I don't know what I'm trying to achieve falls into 'routing' or 'Bridging'???I have two network ports (with static IP ) and I would like to forward RX packets of one to the other.
I have done this in Windows by enabling a service called 'routing'.Is there something similar in Fedora 11? I am pretty sure there are a few thread explaining these but I am just not educated enough to find one that makes sense to me, so Please excuse me for starting a redundant thread and point me to it?

I have installed ubuntu 32 bit version on my HCL netbook. I use reliance netconnect (Huwai EC 1260 or 168c). I have configured it and it works well. But the only problem is that I have to connect the netconnect device before booting. If I connect it when its ON, the networkmanager does not connect automatically. even on the right on the tray icon, enable mobile broadband option is not there.

I have gone through a lot of posts about wireless troubleshooting but nothing has solved it. Left clicking the network manager tray icon always says wireless network is disconnected. "Enable Wireless" is checked.

This may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.

I am trying to connect my desktop to my laptop over a non-internet connected LAN, but when i enable the LAN connection on my desktop (the one with the wireless) its internet stops working.
it is a very similar problem to this except that i am using ubuntu for the machine with the two connections.
right now i have my wireless on the 192.168.1.* address space, while the LAN is to be on 192.168.5.*
note: my goal is not to share internet with my laptop, just be able to connect to it and the internet at the same time.
desktop: ubuntu 9.10 , wireless and LAN
laptop: windows xp, LAN only

I've been on a quest to enable full routing through my openvpn tunnel between my office and the colo. Masquerading will work, however it will throw off anything key based and makes a lot of things just more difficult and vague in general. Is there an easy way to do this via iptables? I tried using quagga hoping it would magically solve my problems, however it does not seem to do my routing for me . I just did a basic static route within zebra...

I am fighting with the WOL settings of my Ubuntu box at the moment. The idea is to have an HTTP/SVN server to sleep while it's unused and wake up when it's accessed. So far, wake-on-LAN works and is activated on startup:
[Code]....
As you can see, I also set the wol p flag ('wake on physical activity'). My assumption was that I could convince the device to wake up not only on magic packets, but on any network access. This, however, seems to be wrong.
