HOW-TO talk:Set up Wake-on-LAN for Ubuntu

From Official Kodi Wiki
Jump to: navigation, search

I would like to propose a change to the final portion of the wake-on-lan script proposed to be put in /usr/local/bin/wake-on-lan. I slightly modified the script to do a pre-check to see if the system is already up and running, which makes the script usable within other scripts/commands so you're not always waiting the 10 sec to see if the target computer has come up.

Also, there should be a note included that if you don't use the hostname for the mac address, the ping just won't work.

for j, k in mmap.iteritems():
    if sys.argv[1] == j:
        if not re.search(X.replace('zA-Z','fA-F'), k):
            print "Invalid MAC address [",k,"]; nothing to do!!"
            sys_exit()
        else:
            c,t = commands.getstatusoutput('ping -c 2 %s' % j)
            if c != 0:
                WakeOnLan(k.translate(f1_arg,':.-'))
                print "WOL request has been sent to %s [%s]" % (j,k)
                timer('Waiting for %s wake up..... ' % j, 10)
                c,t = commands.getstatusoutput('ping -c 2 %s' % j)

                if c == 0:
                    print "%s is up and running........\n" % j
                else: print "The host: %s is not running yet, try again!!\n" % j
            else: print "%s is up and running........\n" % j
            break
else:
    print "Host [%s] doesn't exist!!" % sys.argv[1]
    sys_exit()

If no one voices an objection by the end of the week, I will go ahead with my proposed change.

The above has been added to the page, along with a short section on real world use. That could use more examples if anyone thinks of anything.
