The WoL magic packet is only scanned for the string above, and not actually parsed by a full protocol stack, it could be sent as any network- and transport-layer protocol, although it is typically sent as a UDP <https://en.m.wikipedia.org/wiki/User_Datagram_Protocol> datagram <https://en.m.wikipedia.org/wiki/Datagram> to port <https://en.m.wikipedia.org/wiki/TCP_and_UDP_port> 0,]

Everyone, I have not been able to get ether-wake to work waking up other centos 7.6 machines after the upgrade to Centos 7.6. Has anyone else had this problem, and if so any luck with a fix? Greg Ennis

My system is: Intel CC820 motherboard (which supports PME# wake up for wake on LAN) 3com 3C905C which also supports wake on LAN via PME# Linux 5.5 The motherboard BIOS is later than one that reports an issue with WOL and this particular network card was fixed. But when I turn off the PC (shutdown or poweroff commands or front panel button), it cannot be restarted via WOL. The network light on

Has anyone experience with WOL under Centos (5.3).? If so, how exactly do you put the machine to sleep, and how exactly do you wake it up remotely? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

Actually you are not correct. 1st: I didn't quote the wikipedia article,? someone sent that as an answer to my previous post. ??

Hello list I have a shutdown problem. I have a machine with gigabyte GA-G33M-DS2R motherboard. Integrated network card is Realtek 8111B. I can not wake the computer after I shutdown it from FreeBSD. It is a dualboot system - windows xp and freebsd. If I shutdown the computer from windows - later I can wake it up with magic packet. Even if i shutdown the machine on the boot menu with the power

Ok,? I get that, found it before;? "typically sent as a UDP datagram to port 0, 7 or 9, or directly over Ethernet as EtherType 0x0842" The keyword being 'typically',?? but what is it that ether-wake actually uses/does??

Can you be more specific about the hardware? I have a setup of DELL desktop, DELL Server SuperMicro Server and couple other devices. I am using from a cgi script the next on one server to wake the other: /usr/bin/sudo /usr/sbin/ether-wake "XY::XY" -b && echo 1 All of my servers have Intel PRO 1Gbit ethernet nics(2,4,1.. ports per machine). To make the Desktop wakeup I had to do

On a semi-related subtopic, Why do I want WoL? What concrete examples are there where it's useful? I understand what it is and how it works but the "why" has eluded me. -- Drew "Nothing in life is to be feared. It is only to be understood." --Marie Curie

Hello, I use several applications that allow for authenticating against a Microsoft ADDC natively. Can someone point me in a direction on where to start? I'm using Samba 4.2.0 on Ubuntu 12.04. I think these are the steps I need to take but would like confirmation before attempting. Thanks. Step 1 Method 2: Connecting to AD via Kerberos :

?Hi, I was wondering if anyone has managed to get the preload_app and SIGUSR2 combination working well with upstart? My issue currently is that when I perform a SIGUSR2 against the master, check everything''s working and close off the old master, upstart then attempts to restart it because the original PID/binary are no longer running. What is the correct way of handling this? In my

Hi Quentin, I have tried to find a test case for an official target, but failed. It seems to be a rare case. To do it, I added the 'else' clause in the following: ... if (VNI->def == OrigVNI->def) { DEBUG(dbgs() << "orig phi value\n"); SVI->second.DefByOrigPHI = true; SVI->second.AllDefsAreReloads = false; propagateSiblingValue(SVI); continue;

Many thanks to those that responded to my original posting with information about Network UPS Tools and commercial UPS products. In our planning a path forward to implement UPS-based power fail protection, we have come across what appears to be an issue with the state of the CentOS 6 machines being UPS protected.? Most of these machines are desktop/deskside machines that are likely to be idle

Hi Jonas, Thanks for your patience. After spending some time looking at the additional output you gave me, I agree that your fix is the right one. I was worried that this problem may arise because we were spilling not real user, but in fact what I thought was the problem is an optimization we could do :). See my comments inlined for a few nitpicks before you commit. Thanks again, -Quentin On

Hello, what port does ether-wake use?? (I believe it is port 9? but not sure). Ron
