Copying files from one server to another on regular bases

[Ganesan R]

Hi Salman,

ssh-keygen is secure shell command.
You need to find if you have installed secure shell product on your server.

#swlist |grep -i secure
#swlist |grep -i ssh

If it is not installed you can install HP ported Secure Shell or openssh which is avialble in net.

HP secure shell can be downloaded from above link.

openssh is here.

hi,
Thanks, its working, but very very very slow. Why? FTP is quite fast. Can i make it fast like FTP? On my LAN, the transfer rate is 3MB per second
Thanks

How to do this if i want to use ftp. Can anyone tell me what should i write in the script for using ftp command to do the same operation. I can provide password within that script for the usser which will be used to connect for files transfer using ftp.
Thanks

Salman,

scp, sftp are always going to be slower than ftp due to the encryption.
You can write an ftp script including user/passwd information but this is not the best policy security wise.

You can use this:

ftp -n server <user username password
cd /directory
put file
bye

Here is an extract from a script we use:

IPADDR="192.168.2.1"
USERNAME="remoteuser"
PASSORD="remotepassword"
SOURCEFILE="/home/username/file"
DESTFILE="/home/remoteuser/file"
(
ftp -vin <open $IPADDR
quote USER $USRNAME
quote PASS $PASSWORD
put $SOURCEFILE $DESTFILE
quit
END_SCRIPT
) | grep "226 Transfer complete." > /tmp/ftp$SRCFILE


The assignments for IPADDR, USERNAME, PASSWORD, SOURCEFILE and DESTFILE should be changed as appropriate. Please also note that the target directory structure needs to be in place (same restrictions as 'cp').


I would suggest that from a security point of view scp is a much better solution and should be used where possible.

Apologies for almost repeating the posting from Richard - didn't see his response until after I had replied.

Can "rcp" work without suplying any password just like "scp" works? If yes then how to setup this.
Thanks

Salman,

Just create .rhosts in $HOME on the target server with:

sourceserver user

and then try rcp. With this in place it should not prompt for a password.

regards,

Richard

>Richard: Just create .rhosts in $HOME on the target server with:

If your $HOME is over NFS, you can just list every machine in .rhosts with permission 600 and owner of the user:
machine1
