Many thanks Ivan! I would like to use your script but when I run it I
get the error:
$ ./guac_wol.py
File "./guac_wol.py", line 64
logfile =
^
SyntaxError: invalid syntax
I don't know python and I can't understand why I get this error in your
script...

Well that answers something I was curious about...
... the online Nabble instance doesn't display Unicode 6.0 chrs (well, a
thumbs up U+1F44D at least), but it does pass it on in email.
Anyway I'm pleased the WOL script's working with the right NIC :-)

Thank you very much indeed; in effect I was trying to test your script
with a notebook that was connected to the lan using the wireless card
and the wireless doesn't seems to support WOL... (^_^;)
Any way with network cards WOL capable your script seems to work very
well...
Thank you very much!

Re: guacamole and wake-on-LAN
Posted by ivanmarcus <iv...@yahoo.com.INVALID>.
First of all you can check if the WOL function is working correcly in
the machine you're trying to wake up by using the 'wakeonlan' command
from your Guacamole machine.
eg. wakeonlan 2D:4A:54:58:FB:FA (obviously changing the MAC to the
correct one for your target machine). Etherwake would also do the same job.
If wakeonlan isn't installed just apt-get install wakeonlan (assuming a
debian-based distro).
If that doesn't work you'll need to sort out the target machine.
Otherwise if it does work then there could be a problem with the format
of the macs.list file, or the id number/MAC in the macs.list file isn't
correct for that connection.
To check this out - tail catalina.out when you attempt a connect to the
machine and ensure the connection number is the same as that in the
macs.list file (with associated MAC for that machine).
The WOL part of the code is fairly standard, but if all else fails you
could try something like this (save it into a new file, eg wol2.py, and
run it same as the other - you may need to change the location of the
macs.list file, and catalina.out if you're using a different version of
Tomcat):
#!/usr/bin/env python2
import subprocess, csv, sys
logfile =
subprocess.Popen(['tail','-F','/var/log/tomcat8/catalina.out'],stdout=subprocess.PIPE,stderr=subprocess.PIPE)
while True:
line = logfile.stdout.readline()
with open('/home/user/macs.list') as inifile:
reader = csv.DictReader(inifile)
if 'connected to connection' in line:
q1 = line.find("\"")
q2 = line.find("\"",q1+1)
q3 = line.find("\"",q2+1)
q4 = line.find("\"",q3+1)
user = line[q1+1:q2]
conn_num = line[q3+1:q4]
for row in reader:
if(row['id']) == conn_num:
# print (conn_num)
# print(row['mac'])
m=(row['mac'])
# print (m)
subprocess.call (["wakeonlan", (m)])
This is largely the same code but it'd call wakeonlan to wake the
machine up, and pass it the correct MAC. You can remove the comments
from the print statements to check how the code is performing and if
it's got the correct detail (the connection number and MAC address
should appear in your terminal when a connection is attempted).

ooops, it's my fault, the macs.list was not configured properly...
Any way doesn't seems to works... in effect it's the WOL function that
doesn't wake up the PC...

thank you very much Ivan! ...but I get another error:
$ guac_wol.py
Traceback (most recent call last):
File "./guac_wol.py", line 88, in <module>
if(row['id']) == conn_num:

Piviul,
It looks as if the mailing list has introduced a new line where there's
not meant to be one. Apologies for not noticing that earlier.
The line "logfile =" is meant to read:
"logfile =
subprocess.Popen(['tail','-F','/var/log/tomcat7/catalina.out'],stdout=subprocess.PIPE,stderr=subprocess.PIPE)"
- all on the one line.
I suspect in your script you'll just need to bring up the text in line
below "logfile =" and tack it on the end for it to work.
