General :: FTP "ASCII" Mode - RFC 959 - "File Transfer Protocol"
Jun 8, 2010
[ This thread is a result of <<mod edit---another thread>> RFC 959, "File Transfer Protocol", dictates:
Code:
3.1.1.1. ASCII TYPE
This is the default type and must be accepted by all FTP implementations. It is intended primarily for the transfer of text files, except when both hosts would find the EBCDIC
type more convenient.
The sender converts the data from an internal character representation to the standard 8-bit NVT-ASCII representation (see the Telnet specification). The receiver will convert the data from the standard form to his own internal form. In accordance with the NVT standard, the <CRLF> sequence should be used where necessary to denote the end of a line of text. Regardless of <<mod edit--another member's>> attempt to misinform and claim some sort of expertise in whatever, the ASCII mode works as expected.
Quote:
// From <<mod edit---another thread>>
So, go on, vi a document in linux, save it with a .txt extension then ftp get it from a windows machine. Make sure to open it with Notepad. I am writing this post from the very same Windows machine I used in order to conduct the exact experiment you are suggesting. The text file has been successfully converted. If it has not worked for you in about 20 years, I would suggest you start using an FTP server that does not suck, or for the very least one that respects the FTP standard. It is also possible that you used a client which does not use ASCII mode by default, in which case we are dealing with PEBKAC rather than with bad server software.
The purpose of this thread isn't to continue the odd debate regarding signatures that was starting in <<mod edit---another thread>> but rather to (hopefully) protect various users from trusting <<mod edit--another member>> in this certain (FTP) matter. Tinkster closed the thread just as I was preparing to post, thus giving <<mod edit--another member>> the last "word". Once again: he doesn't know what he is talking about, despite his "doing this for over a decade". I'm wondering if "this" means "spreading misinformation and reinforcing it with claims of being an expert".

I want to transfer file using ftp protocol. I m using following linux distribution.
PHP Code:
LSB Version::core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: OracleVMserver
Description: Oracle VM server release 2.2.0
Release: 2.2.0
Codename: n/a
When I run PHP Code:
[root@OFSMUW-VS-51 ~]# service ftp status
output is
ftp: unrecognized service
How would I install FTP? Do I need to install ftp server or client? Where would I get suitable ftp server/client for my distribution. Some rpm related to ftp are already in my machine please find the details
PHP Code:
# rpm -qa | grep ftp
ftp-0.17-35.el5
lftp-3.5.1-2.fc6
tftp-0.42-3.1.0.1

I had a problem with the old good ascii/binary FTP transfer modes. I transferred some files (SQL scripting files, in which carriage returns DO matter) using FTP from a windows system to a linux system using filezilla "auto" mode, that should have resulted in ASCII mode for my sql files. These files are well formed and identical to the originals.
Then, someone else picked these files and moved them to another ftp server. I finally found that all <CR><LF> couples have been transformed in <CR><CR><LF>. I guessed that the problem was in the ASCII transfer mode - but, how comes that <CR><LF> => <CR><CR><LF>? I would have rather expected <CR><LF> to become <CR>.

I am trying to download a EBCDIC file from z/Os to UNIX using FTP in ASCII mode. The problem I am seeing is; when UNIX FTP Client issues a get; UNIX CPU goes to 100% CPU utilization when transferring a file in ASCII mode. I have done packet traces using wireshark and noted that z/OS Server is translating the file to ASCII before putting it on the wire, however when UNIX FTP Client gets the file I believe that the UNIX FTP Client is again translating the file to ASCII causing the 100% CPU utilization. I need verification that this is what is happening, and is there a way of getting around this other then transferring the file in binary mode then doing a EBCDIC

I just uploaded JPG pics from a Win XP, through shell, on my FTP.When I downloaded them back (to a UNIX machine), they were all currupted and unreadable !After some researches, I found that Win XP's shell works by default in ASCII mode.

Having a bit of a issue with Debian Squeeze and transferring files to the Sony PSP..Hook up PSP to USB port and Debian mounts it..I go to drag a 125 meg mp4 to video folder..Copy windows takes about 10 seconds to transfer it..Exit USB mode and there is no video there. Go back into USB mode and look at video folder on the PSP memory stick and there is no video..It vanished. From another after copy progress closed I right clicked PSP and unmounted it..
It error-ed saying device was busy and could not unmount..Looking at light on PSP i see memory stick is still being written to..i wait for light to stop flashing..About a minute or so..Then am able to unmount it..Go to PSP video and theres the video ready to be watched. Debian isnt accurately showing the copy progress...Its showing complete when it isnt..I have to watch the light on PSP to know when it is truly finished.

To start off I would like to acknowledge that I am not a very good C programmer and pretty much everything I know has been self taught through mostly trial and error. So forgive me if there is an obvious answer to my question, or if I don't immediately grasp the concepts involved in the possible solution.
Basically, I'm writing an application which will be creating log file entries rather rapidly (potentially hundreds per minute), and I would like each new line to appear at the top of the log file, rather than the end. Opening a text file in append mode is easy enough, but I can't seem to find any obvious way to do the opposite.
I have been looking online and it seems that there exists no standard way to do this, and I have only been able to find a few mentions of how somebody might achieve it. The most common method seems to be using two files and copying the data back and forth between them. This seems like it would be insanely I/O intensive with the number of lines I'm likely to be generating. If this is the best method to use, I will give it a shot; though I am not 100% clear on how to implement it, I am also open to any other ideas as to how to accomplish this, and I don't have to worry about portability since the program already uses Linux-only libraries. So calling out to sed or something is not necessarily out of the question (though I imagine performance would also be an issue there).

I am transferring a file from a linux pc going to a windows ftp server using "ftp put". My file is a zip file that includes .txt files inside it. Here is what's happening when I transferred this file :I used ftp put for transferring and found that my transferred zip file was corrupted and couldn't be opened on the ftp server.I found the solution for this on the internet. I needed to use 'binary' to make it right.
I transferred again using binary and then ftp put the zip file onto the other end. Yes, it worked. My zip file wasn't corrupted anymore and I could already opened it on the ftp server. But the problem remains on the .txt files inside it. Converting the file into binary made my .txt files to be distorted and unreadable. I read from the internet that .txt files need to use Ascii instead of Binary to be readable, but if I use ascii it would cause my zip file to be corrupted again. I need to successfully transfer a zip file that contains .txt files using ftp put.

I have 2 linux computers, and a serial line between them, one of them is only accessible through a serial line that has shell on it. How can I transfer files between the 2 computers?
I've heard that it can be done with some rz/sz magic...
Can I do the same trick with a pseudo-terminal instead of other computer?

I work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.
