Shell Programming and Scripting

Hi,
I have a cronjob to fetch bill.txt via sftp from a external server to my UNIX server and then rename file to bill.V01.txt (on remove server)
I am able to fetch the file successfully, but I added below line in my script, which should rename file on remote server, it is failing

Code:

ssh -q user@ftp.xxxxxx.com  mv bill.txt bill.V01.txt

If I run it manually, it says "Connection to ftp.xxxxxx.com closed by remote host." Where could be the issue ?

First check /etc/hosts.deny and /etc/hosts.allow, if all fine
try to restart ssh using /etc/init.d/ssh restart may be its due too many concurrent connections. BTW what's in the logs on the server ? if you post then that might help us to solve the issue.

Akshay, sftp was able to connect successfully and fetch file from there, so I was assuming that it should be able to move file also on remote server. I do not access to remote server, but if I know what needs to be checked, I can ask remote server admins to give me outputs of logs/data. Is my command right ?

Code:

ssh –q user@ftp.xxxxxx.com  mv bill.txt bill.V01.txt

Yes your command is right. it's always good if you enclose multiple command line arguments using a single or double quotes.

example :

Code:

$ ssh user@host 'mv file1 newfile'

The -q will prevent ssh from telling you what's going wrong...

ssh is not getting connected. Tried without -q also, it never gets connect. While with sftp, I can fetch files.

Can you check if you are able to telnet the FTP sever from you server mentioning ftp port
telnet servername ftpport.
