Solaris

Hi all,

I have done google on the aforementioned subject. But didn't find any authentic way of checking 100% Successful FTP transaction.
In my case I have critical backup of source code on daily basis. I have shell script which will:
1: "mput" backup files to remote server using FTP
2: delete backup files from source server.

Problem is that I am not able to find a way through which I can ensure backup files are successfully transferred (mput) and now its safe to delete backup files from source server.

Here is the shell script:

Code:

#!/bin/sh
#
BACKUPDIR="/export/home/myuser/backup"

HOST='ftp.xyz.com'
USER='user@xyz.com'
PASSWD='abc'
FILE='*.gz'

ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
lcd $BACKUPDIR
cd backups/source
binary
mput $FILE

quit
bye
END_SCRIPT

Any help is highly appreciated.

Bye
Viki

Had a similar issue recently with sftp, it's not possible unless you log in with a new session and get a listing of the remote directory.
Better to use rsync or scp, they will at least give you a return code.

Your idea is good. But when I try scp to remote server; I get "connection timeout". This remote server is of Yahoo where we have purchased domain and have infinite space. It is connecting with FTP but i think scp/rcp/rsync are disabled on it. How can we check that remote server - Yahoo support scp ? I have read Yahoo web hosting documentation but didn't find anything in this regard.

You have to edit your script. Use a loop from 1 to n where n is the number of your files. Also, use put instead of mput. and make a checksum on each file before you send it. do a remote checksum on the yahoo server on the same file. if the both values match delete the file, else resend it. exit the loop when you reach n+1.

please ask me if you need any help in you script

To be honest for this task is maybe reasonable use expect script. I suppose that via this you can handle much more specific needs.

If you 'tar' and 'gzip' them first, then you will only have a single file to send and compare. But, since this is source code, I would be inclined have the date as part of the file name and maintain multiple copies.

what is the file name format?
