I am doing a C/S project in which one of the function is a downloading file from the server.
The client is written in python and the server is written in java.
-f filename is a command that fetches the file.
The only problem is in the
def download(self,filename):
print "Start download file"
self.sock.send("DOWNLOAD"+"sprt"+filename)
downloadData = self.sock.recv();
print downloadData
and
if message[0:message.find(" ")] == "-f":
if not (message.split(" ")[1]) or len(message.split(" "))>2 :
print "Usage -f filename\n"
else:
client.download(message[message.find(" ")+1:])
part.
AttributeError: 'timer' object has not attribute 'download'.
In contrast the
def upload(self,filename):
print "server ready , now client sending file~~"
try:
f = open(filename,'rb')
while (True):
data = f.read();
#if file is none
if data is None:
break;
#Notify the java server that a file is going to be sent.
#sprt stands for seperator
self.sock.sendall("FILE"+"sprt"+filename+"sprt"+data+'\n')
break;
f.close();
time.sleep(1)
#Notify the java server that the file is complete
self.sock.send("EOF\n")
print "send file success!"
except IOError:
print "No such file or Directory"
the method works normally.
What might cause the problem ? Thanks
Here is the whole file.

The file you are using differs from the one you've posted here in one significant aspect: indentation. Your download method is either indented too much (that would make it defined while running upload) or too little (that would make it a module-level function, instead of one associated with timer). Make sure that the indentation around def download is correct, i.e. 4 spaces.
While you're at it, the line
downloadData = self.sock.recv();
will need some modification too. Most likely, you want something along the lines of
downloadData = self.sock.recv(4096)

I have a program that i'm trying to create for the purpose of searching the network for specific mac addresses.
When I run the cisco command "show mac-address-table" it gives output that's saved to MH2. If that output has "000c." in it all the output is saved into a txt file that i'm hoping i'll be able to filter through and pull the vlan from based on the command used (show mac address-table vs show mac-address-table) as the vlan location for the line with the mac address could be to the left or the right. I'm planning on figuring that part out later, but for now it doesn't seem that my script is reading the file(which is getting the correct output and has a "000c." entry in it) I'll enter the code below:

password = getpass()
#
for line in f:
device = (line)
print('Starting to collect information, please wait')
#For those devices in the above list, connect and run the below commands

"if ("000c.15") in (CPMAC)" is the part of the code that I believe i'm having trouble with. any help is appreciated!
Not really sure what you are trying to achieve but check the line OP1 = mactable.read read is a function that should be written as OP1 = mactable.read()
So the below is what has worked for me so far, I'm able to run the command "show mac address-table", take that output and put it into a text file, search line by line through the output for 000c.15 and use that line for further output later down the road. I think the important thing was to decode the output(bytes) into a string before writing it to the text file. Also, using the seek(0) function was helpful for taking me back to the beginning of the txt file before starting to read. Line.strip seems to get rid of all the white space being interpreted as lines. not 100% sure on that last one. Still having issues with getting that code to send the command but i'm making progress at least. Thanks everyone for your help.
if (b"000c.15") in MH2:
print("000c.15 in MH2, line 57")
try:
print ("line 59")
sleep(.5)
mactable = open("mactable.txt", "w+")
mactable.seek(0)
mactable.write(MH2.decode('utf-8'))
mactable.truncate()
mactable.seek(0)
OP1 = mactable.readlines()
for line in OP1:
line = line.strip()
CPMAC = line
Unable to produce from the device, made a separate function in running a simple method wherein I have a list of devices and command.
But from this script, seems like I can't send the command to the device? I'm not sure whether script can connect successfully. So I put a print on connect to device part just to determine the location.
From the output of the print is
Connected 0 <-from beg_rm
THIS IS THE COMMAND show ip int brief <-send_cmd
Would like to ask if my method is correct in connect and sending command using this function and argument?

It seems like you're expecting beg_rm() to return the child object, instead of an integer?
I am learning Python right now, and try to write a small file transfer program. The following is my codes.
This is the server codes
import SocketServer

def recv_all(self,obj, msg_length, des_file):
while msg_length != 0:
if msg_length <= 1024:
print 'here3'
print msg_length
print type(msg_length)
data = obj.recv(msg_length)
print data
msg_length = 0
print 'here4'
break
else:
data = obj.recv(1024)
msg_length -= 1024
#print msg_length
des_file.write(data)
print 'here4'
return 'Done'
def handle(self):
print 'Got a new conn from', self.client_address
while True:
cmd = self.request.recv(1024)#receive data from client
print cmd
if not cmd:#deal with ctrl+c from client
print 'Lost connection'
break
CMD = cmd.split()
print CMD
option, filename, file_size = CMD[:3]
print option
print filename
print file_size
if option == 'put':
#client wants to upload file
f = file('temp/%s' % filename, 'wb')
print 'here'
write_to_file = self.recv_all(self.request, int(file_size), f)
print 'here1'
if write_to_file == 'Done':
f.close()
self.request.send('File uploading done')
if __name__ == '__main__':
h = '0.0.0.0'
p = 9002
s = SocketServer.ThreadingTCPServer((h,p),MySockServer)
s.serve_forever()
The client codes:
import socket, os
host,port = '192.168.73.11', 9002
c = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
c.connect((host,port))
while True:
user_input = raw_input('msg to send:: ').strip()
if len(user_input) == 0: continue
user_cmd = user_input.split()
if user_cmd[0] == 'put':
if len(user_cmd) == 2:
f = file(user_cmd[1], 'rb')
f_size = os.path.getsize(user_cmd[1])
print user_cmd[0], user_cmd[1], str(f_size)
c.send('%s %s %s ' % (user_cmd[0],user_cmd[1],f_size))
print 'going to send....'
c.sendall(f.read())
print c.recv(1024)
c.close()
I just inserted some prints into the codes to find where are the problems. I found that in the recv_all() function in server codes, the sentence 'data = obj.recv(msg_length)' in the 'if' part cannot work, but the sentence in the 'else' part works very well. Is there anyone can tell me why could this happen?
Thanks guys.

WLContext.close() is probably not the real problem (it's even in some of the Oracle examples). What error messages do you see when deploy and undeploy are being called?
You should see something like:
Deploying application from /tmp/something/myapp.ear
Current Status of your Deployment:
Deployment command type: deploy
Deployment State : completed
Deployment Message : no message
I also see that you never call activate() at the very end of your script so that could be the issue if you are running in production mode.
Try adding the following at the very end of your script after deployMain():
save()
status = activate(300000, "block='true'")
status.getStatusByServer()
status.getDetails()
UPDATE:
The activation error occurs because you have not called edit() before the undeploy:
# Get edit/lock for upcoming changes
edit()
startEdit(120000, 120000, 'false')
undeployApplication()
I think you will be better off greatly simplifying your undeploy. You don't need to go through the complexity of determining targets because you are already undeploying from ALL targets. Try this instead and see if you can make progress:
cd ('AppDeployments')
myapps=cmo.getAppDeployments()
for appName in myapps:
try:
appPath = "/AppDeployments/" + appName.getName()
cd(appPath)
print "Stopping deployment " + appName.getName()
stopApplication(appName.getName())
print "Undeploying " + appName.getName()
undeploy(appName.getName(), timeout=60000)
except Exception , e:
print "Deployment " + appName.getName() + " removal failed."
On line 51/52, I get the error:
Unindent does not match any outer indentation level.
I understand this has something to do with tabs and spaces.
Note I did not write this code, I found it online and plan to modify it.

Python code is sensitive to the indent level you use. Your code reads:
if (process_data.find("adios") == 0):
client_socket.close() #Close socket connection
print ("<Ctrl+C to exit.>>")
break;
Inside the if block, the statements must all line up. Notice how client_socket.close() and the following print statement have different indent levels. You need to change this so that they both have the same indent, like this:
if (process_data.find("adios") == 0):
client_socket.close() #Close socket connection
print ("<Ctrl+C to exit.>>")
break;
The code presently reads:
if (process_data.find("adios") == 0):
client_socket.close() #Close socket connection
print ("<Ctrl+C to exit.>>")
break;
The first statement in the body of the if is indented 6 spaces, while the last two statements are only indented by 1 space. The indentation level ought to be same and consistent throughout the program, something like this:
if (process_data.find("adios") == 0):
client_socket.close() #Close socket connection
print ("<Ctrl+C to exit.>>")
break;
The indentation in the code doesn't seem very standard (or consistent). For instance the body of the while loop in 41/42 is indented more than other bodies of similar statements, e.g., lines 31-33, that's trouble in a language like Python where whitespace matters.
Finally, note it's not a good idea to mix tabs and spaces. PEP 8 -- Style Guide for Python Code recommends the use of spaces over tabs and an indentation of 4 spaces per level.
