Re: [Tutor] socket / over network
in case it helps here is a very basic example:
import MySQLdb, glob, os, re, shutil
from ftplib import FTP
a=file_to_fetch
ftp=FTP('ftp_server')
ftp.login('user_name','password')
try:
aa=ftp.nlst(a)
b='/home/a'
bb=os.path.basename(aa[0])
e=os.path.basename(b)
c=open(b, 'wb')
ftp.retrbinary('RETR '+aa[0], c.write)
c.close()
well u just copied some pieces of my own code to maybe help you get started
with ftp as you maybe don't know that you have to open a file for writing &
then write into it the stream from ftp retrieve cmd.

There are number of problems with FTP around security and firewalls, etc. This might be overkill, but perhaps you could use Twisted with SSH/SCP to get files around? See; [Twisted-Python] Twisted SCP http://twistedmatrix.com/pipermail/twisted-python/2005-December/012180.html Perhaps using Rsync and SSH might be more appropriate; http://www.howtoforge.com/rsync_incremental_snapshot_backups regards, Kim -- Operating Systems, Services and Operations Information Technology Services, The University of Adelaide [EMAIL PROTECTED] ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

For a very simple example of using a socket you could try the Network Programming topic in my tutorial. There is also a HowTo or Topic guide on the Python web site that gives a more detailed example. That having been said, backups are usually best done using OS tools or if you must roll your own then using ftp or similar as a file transfer mechanism rather than trying to send a bytestream over a socket. ftp can handle broken connections etc more easily.

[Tutor] socket / over network
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hey guys, I'm pretty tired of the lame backup solution we have at work. Could anyone point me to a (more or less newbieish) example of how to have python open a socket on one box and get data from it, then have another box write to it over the network? I'm having trouble finding something like this.
