ftplib

I would like to retrieve the data inside a compressed gz file stored on an FTP server, without writing the file to the local archive. At the moment I have done from ftplib import FTP import gzip ftp = FTP('ftp.server.com') ftp.login() ftp.cwd('/a/folder/') fileName = 'aFile.gz' localfile = open(fileName,'wb') ftp.retrbinary('RETR '+fileName, localfile.write, 1024) f = gzip.open(localfile,'rb') data = f.read() This, however, writes the file "localfile" on the current storage. I tried to change this in from ftplib import FTP import zlib ftp = FTP('ftp.server.com') ftp.login() ftp.cwd('/a/folder/

So lets say I'm using Python's ftplib to retrieve a list of log files from an FTP server. How would I parse that list of files to get just the file names (the last column) inside a list? See the link above for example output. Using retrlines() probably isn't the best idea there, since it just prints to the console and so you'd have to do tricky things to even get at that output. A likely better bet would be to use the nlst() method, which returns exactly what you want: a list of the file names. e-satis This best answer You may want to use ftp.nlst() instead of ftp.retrlines() . It will give

I have a FTP connection from which I am downloading many files and processing them in between. I'd like to be able to check that my FTP connection hasn't timed out in between. So the code looks something like: conn = FTP(host='blah') conn.connect() for item in list_of_items: myfile = open('filename', 'w') conn.retrbinary('stuff", myfile) ### do some parsing ### How can I check my FTP connection in case it timed out during the ### do some parsing ### line? Sean Dawson Send a NOOP command. This does nothing but check that the connection is still going and if you do it periodically it can keep

I need to download a file from a host using sFTP. Do you know if is it possible to do that using python ftplib? I saw an example here , but when I try to connect I receive EOFError . I tried this code: import ftplib ftp = ftplib.FTP() ftp.connect( "1.2.3.4", "22" ) This method returns with an error after long time so I cannot perform a call to login. I cannot try the constructor FTP([host[, user[, passwd[, acct[, timeout]]]]]) because my port is 22 but ftplib default is 21. If I follow the example ftp = ftplib.FTP("1.2.3.4") ftp = ftplib.FTP("1.2.3.4","22") I receive a connection refused so I

I'm using FtpLib (Python) to download a folder with files from an ftp server. But I want to know the size of the folder before I start downloading it. In the documentation I found FTP.size(filename) but that's just for files and not for folders... I could loop through all the files in the folder but it is possible that the folder contains subfolders. So does anyone know how to get the size of the folder using FtpLib? After some trial and error I found the solution. It's based on Alex Thorntons solution but I kept in mind that there could be subfolders. When it's a folder, the ftp.cwd() command

I'm appending values to a log file every 6th second. Every 30 sec I'm transferring this log to a server as a file. But instead of transfering the whole file, I just want to append the collected data to the file on my server. I haven't been able to figure out how to open the server file and then append the values. My code so far: session = ftplib.FTP(authData[0],authData[1],authData[2]) session.cwd("//"+serverCatalog()+"//") # open server catalog file = open(fileName(),'rb') with open(fileName(), 'rb') as f: f = f.readlines() for line in f: collected = line # In some way open server file, write
