I'd like to amend it to sftp mode. Please advise the correct step.I consulted the man pages of sftp and I suppose I should be using the sftp -b option.
what should I be storing in my batch file? I'd like to retain my use of the variables $my_user and $my_pass,$myDIR,$ftp_cd,$OPS(get or put),$my_file because they are passed in from another script
Hi,
I'm being told that I have to start using SFTP from my server (HPUX 11i), so heres a few questions;
What are the differences between FTP and SFTP? What differences in congiuration can I expect? Are there any changes in command usage? I did see an earlier thread with command issues. A few... (3 Replies)
Hi,
I have the following ftp code to check the status of communication channel :
/bin/ftp -i -v -n -B 64 $HOST <<END 2>&1 > $LOGFILE
user $user $password
bye
END
I need to re write to use SFTP, I know how to do SFTP with authentication keys.
But my problem is, when the authentication... (0 Replies)

Good morning all,
I require some help regarding an FTP server i am building.
Basically i have around 20 users all sending a receiving files to and from my FTP server but would like all traffic to be secure. I want to ensure users connect via SFTP only and are denied via FTP.
Im using... (1 Reply)
Somebody made a policy that 'we use sftp now instead of ftp'. I have recommended we use scp because I can't for the life of me think of a *good* reason to use sftp and not scp. But most of what I do is stupid stuff without a good reason. I get judged on how much I can just say yes, no matter how... (1 Reply)
I am not very familiar with the use of FTP, and trying to run it I found out that standard "ftp" is not working" but "sftp" is.
If sftp is allowed will that block ftp ? and if so where is this set ?
I thought there is no relationship, is that right ?
If so look here:
inetadm | grep ftp

Hi All,
I am in the process of replacing SFTP instead of FTP to make data more secure. In one of my FTP script I have Quote Site command. I would like to know, what is the option to replace this in SFTP
ftp -n -v <<! | tee -a $LOG | grep "Transfer complete" >/dev/null

Hi Friends,
I need to make a Unix script, where i need ftp and sftp functionality.
Let me describe in details:
I need to import few files from remote server, now these remote server either support ftp or sftp not both. So i need a script where my script will try to do ftp first and if it... (8 Replies)
Hi all.
I can put ftp command in shell script together with the password using
ftp -n 10.1.2.34 << EOF
user userid password
cd /test_dir/
prompt
bin
get filename.txt
EOF
But the -n option is not available for sftp.
What alternatives do I have then to bypass the password prompt?

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
