Ubuntu :: Magic Packet Received / But Wake On Lan Doesn't Work
Oct 15, 2010
I am trying to remotely wake up my computer. I am using the wakeonlan tool as follows wakeonlan -i 146.x.x.x 00:0f:.I have used wireshark on the remote computer and verified it was getting the magic pack. wireshark sees the packet, and immediately the remote computer sends an ICMP dest. unreachable (port unreachable) packet back, although I assume that is normal.On the remote computer, I used ethtool so I am enable to verify that suports wake-on is set to "g" or magic packet.
I believe that wake-on-lan is enabled in the bios. I have a hp dc5000, so I turned on S5 wake on lan in the bios. However, the computer does not wake up.My assumption is that once the computer is off, the router doesn't know where to send to packet because that ip is not there anymore. Does that make any sense? What other troubleshooting steps can I take? I don't have control over the routers though.
On Linux, is root privilege required to send a wake-on-lan magic packet? If it depends on how you send the magic packet, please let me know under what situation root is required.
As i am posting in this forum you might already have guessed that I am a total linux noob, but I am a pretty faster learner. I know a few basic things but I feel like I am stuck with my problem.I want to send the Magic packet (wake on LAN) from my linux machine to another, but I am unsure how to approach this. I have google�ed my ass off but I am none the wiser. I found a few forums posts and programs that can do the trick and guides in how to use the programs but I have no idea how to install them.You have to know that my linux machine is a NAS server and has therefore only Konsole access (no GUI). As I said before I am pretty much a noob
I'm getting some trouble with Wake on Lan. The main question is: when I shutdown a PC through Windows, the WOL works well, but it doesn't happen when I shutdwon the same PC through Linux. It happens in all of my PCs here in the company.
How to get the length of received UDP packet? Using wireshark I could see the correct length of datagram. How can I print this value in my simple udp server program? I am receiving binary data (Non printable ascii characters as a data) So I can not use strlen(buf) which throws incorrect length.
Code: if (ret=recvfrom(s, buf, BUFLEN, 0, (struct sockaddr *)&si_other, &slen)!=-1){ error = ioctl(s, FIONREAD, &value); printf(" from ioctl UDP packet length is : %d error is : %d ", value, error); code....
I run Ubuntu 10.04 and everything worked fine until I downloaded bunch of games and programs using synaptic and it stopped working. When I try to install anything it tells me to check my internet connetction which i know works just fine, it says that cannot connect to [my_ip]:8080 and I manually opened the port and nothing, i disabled the firewall and have no proxy running, it also gives me the info that connection(111:refused) What do I do?
I'm posting an E-Mail I sent to Pidgin Support, which didn't get answered. I'm doing this because I believe it is a general SSL problem. I've even tried a different chat client (Instantbird) - same error message. Since a week or so I'm not able to securely login to ICQ any longer with one of my accounts. Only if I disable "Use SLL" in the advanced settings, it works. With SSL I get the error message "Unable to connect to BOS server: SSL Handshake Failed". In the debug window the reason for the failure is "A record packet with illegal version was received". If I enable the setting "Use clientLogin", I get a different error: "Received invalid data on connection with server".
I get this error for all of my ICQ accounts if I enable this, but the other ones work just fine using only "Use SLL". I can login to the ICQ website with the "bad" account too, the settings are exactly the same for all 3 accounts. I was using Pidgin 2.7.3 when this happened first, upgraded to 2.7.5, but no change. I'm running RHEL 5.5 x86_64. I've attached the Pidgin debug messages for the "bad" case of the not working account and for the "good" case of one of the working accounts. I've tried a lot of things, like deleting the account and adding it again. I deleted the cached certificates. I changed the password on the ICQ website.
From the attachment I'm only pasting the most important part - the error message:
(20:27:14) gnutls: Starting handshake with bos.oscar.aol.com (20:27:14) gnutls: Handshake failed. Error A record packet with illegal version was received. (20:27:14) oscar: unable to connect to FLAP server of type 0x0002 (20:27:14) connection: Connection error on 0x9bf19f0 (reason: 0 description: Unable to connect to BOS server: SSL Handshake Failed)
I doesn't get into my head why 2 accounts work perfectly, but one doesn't. The login-server is exactly the same, so also the used certificate should be the same.
I'm working on an application that makes http requests using HttpRequest and it's been doing what I need so far without a problem. Now I need to make https requests as well and when I try to make the request, i get this error message:
Code: Fatal error: Uncaught exception 'HttpInvalidParamException' with message 'Empty or too short HTTP message: ''' in /home/antoranz/waneesia/html/index.php:0 inner exception 'HttpRequestException' with message 'SSL connect error; gnutls_handshake() failed: A TLS packet with unexpected length was received.

i made a video and i wanted to put it on my myspace(video upload) and it justs fade to grey and becomes unresponive. that it goes back to normal but no progress. so then i tried going to image shack and uploading a picture. can't do that either. tried mediafire, videos, vimeo, nothing.
so i tried on my desktop(desktop running 9.10 32 bit. laptop(the first one i tried) running 9.10 64 bit. it didn't work on that either. i know it's not my isp because it works on my ps3(no ubuntu). not my firewall and tried without without my router. didn't work either. i tried upgrading flash on both of them and on my desktop i can upload some pictures to imageshack now. nothing else though. i have tried using both firefox and opera.
i pinged yahoo and this is what i got:
6 packets transmitted, 6 received, 0% packet loss, time 5007ms rtt min/avg/max/mdev = 72.732/73.437/75.024/0.761 ms
I installed the Centos 5.5 and after the Xen. After I put a virtual machine named VM01.Initially it worked properly, I tried everything and it worked.When rebooted, I had problems with the network.I have two network cards eth0 and eth1, but eth1 does not have any ip and I use only eth0.The error that appears is:
vif0.0: received packet with own address the source address
I was just introduced to Linux official a few days ago : The problem I am having I am trying to Set up Magic Jack on Ubuntu 9.10, and I have no clue how to get it to work.
When I put my laptop to sleep (clamshell close) it goes to sleep and is a happy laptop.
When I open the laptop, I can hear the thing going and waking up. However the screen stays off. Brightness keys do nothing. (however they did nothing in the first place as I'm using the NVIDIA driver). I have to do a hard reset to fix things.
The strange thing about this is Sleeping / Waking up has never been an issue till about today.
I upgraded from 10.11 to 11.4 and as far as I can see most things work as they did before. However, I have my machine to "go to sleep" (is that suspension or hibernation?) after 2 hours and when I, now after the upgrade, press the "wake up button" the machine fires up but the screen remains down. Ie, the screen is actually not receiving any signals from the computer? Any setting I can change? It worked fine with 10.11!
I'm trying to get WOL to work on my web server built on an ASUS P4A800D-X motherboard (which supports wol).I have it enabled in my BIOS and I've tried several different tools with no results, including my dd-wrt based router which has this functionality built into the firmware.All the guides I've read say it has to be enabled in the driver settings in the Windows Control panel before it will work, but I'm running Ubuntu Server 10.04.
Is there any special steps that must be taken in the OS to enable my web server to power on from the LAN? I've never used this feature before and would like to just shove my web server in a corner some where and have 100% remote control from my main PC.
just setup ubuntu server 10.10 on my new home server, installing usual stuff ect and came to install TCL, however had a couple of errors and done a bit of digging, come across a thread here that told me i needed to enable the 'repositories' packets in my packet manager, then went to open the packet manager and its doesn't recognize my password, although i can use sudo just fine.
i have recompiled kernel on my netbook (lenovo s10-3t).suspend works correctly but then i cannot wake up. i think i just missed some kernel options.what options must be set for suspend/wake up?
I can't get wake up on lan (wol) to work on my network card.The strange thing is that before I had it working with the exact same hardware. But I was on Centos 5.4 then. Now I am on Centos 5.5.Am I correct in concluding that the sky2 driver does not support wake up on lan?
I am the new user to ns-2. I would like to know is it possible to send the keys or some value as the packet data (content of the packet) in ns-2 (for wireless environment).
I got a problem with my CentOS server. Somebody told me OpenVPN Requires different changes inside my firewall settings. That could be the problem why openvpn wont load..I receive this error on my CentOS panel when im trying to connect into the centos openvpn (with my winxp pc):
I am trying to change the IP address of the traffic that has been stored. I have tried different commands:
[code]...
however, either from these two commands end up with a following error:
[code]...
when I searched for a solution and generic commands I used those two websites: website1 website2 Commands have been tested using a casual user account as well as a privileged one (root).
I'm using 'Adobe Flash plug-in 10.3.183.4ubuntu0.11.04.1', installed from the package repos on kubuntu, and since the last update, it has broken all flash functionality in both rekonq and firefox.I have tried removing and reinstalling the package multiple times, both with and without the browsers open. Can anyone suggest a way to restoring functionality?
I install from openSUSE-11.3-NET-x86_64.iso. Installation was succesfull, but after install all packet on test internet / update was error. And after log in in installed system internet not work. I use router with DHCP
When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:
I'm having trouble getting compiz to work on my Laptop. It worked for a while and then I turned on Shift Switcher and a message popped up saying..."The new value for the button binding for the action Terminate in plugin Shift Switcher conflicts with the action Zoom Window of the Scale Addons plugin. Do you wish to disable Zoom Window in the Scale Addons plugin?" I was given the option of Set Terminate anyway, Don't set Terminate, and Disable Zoom Window. I clicked Don't set Terminate and ever since the only thing that works in compiz are the bindings in the general options. I've used synaptic to completely remove and then reinstall compiz but the problem persist. Something else weird, all of the changes I made are still there, even after complete removal, but they don't work?
When I try to hibernate, the computer just goes to a blank, black screen and doesn't turn off. I have to hold the power button to get it to shut down, and when I turn it back on none of the programs running before hibernation have been saved.
I just recently (about an hour ago) installed Ubuntu Netbook edition on my old laptop, and I was greeted with the message, that unity could not be run due to some sort of missing driver...fair enough, I was then greeted with the default Ubuntu desktop, I installed all my needed software (wine, google chrome) and installed the missing display drivers. I then rebooted the system, and once again I am stuck with the default desktop, and not the Unity interface. I checked the software center, and it says Unity IS in fact installed.. And yet I cannot make it appear. So now I ask you Ubuntu veterans. How do I make it work?
P.S. I wiped the system of windows, and the computer is an old HP Pavilion DV6000
