10060, 'Operation timed out'

[Sumit Acharya]

I am using following script to connect to the server and i try the
connection for 1000 times. Some times it succeeds for all the 1000
times,but some times it fails with error:-
10060, 'Operation timed out'. When it fails with the abover error, it
seems timed out time is 20 seconds. Is there a way I can increase the
timedout time for FTP?

from ftplib import FTP
import time
import sys

host = sys.argv[1]
port = sys.argv[2]

for x in range(1000):
try:
y = time.time()
ftp = FTP()
ftp.connect(hos t,port)
ftp.login('a',' a')
try:
print ftp.sendcmd('pa ss x')
except:
print sys.exc_value
ftp.close()
except:
print sys.exc_value
r = time.time()
print "Timeout %d %d %((r-y),x)

when there is error in connecting, it comes to the outer except and
prints the value of r-y as 21. How i can increase this timeout time? or
this error indicates something else?

Please let me know asap,

In a single-threaded program you can import the socket module and then
use the socket.setdefau lttimeout() function to establish a longer timeout.

from ftplib import FTP

socket.setdefau lttimeout(60)

After 20 seconds only.

Of course I now realise there's no default timeout on sockets anyway, so
that likely wasn't the problem.

Which statement is failing?

You would actually get much more information without the try/except
clauses, as they are stopping the traceback from being printed - if the
error is occurring deep in the ftplib you will actually see "what and
where" with a full traceback. Your loop should read:

for x in range(1000):
ftp = FTP()
ftp.connect(hos t,port)
ftp.login('a',' a')
print ftp.sendcmd('pa ss x')
ftp.close()

Try running the script without both try/excepts and then post the full
traceback, please. You can forget about the timings for now. It may well
be an FTP server loading issue, but a traceback will give more information.

regards
Steve

Please keep this thread on for you so that I can get the solution
