automating sftp

so.nimda — Tue, 23 Dec 2008 01:35:16 GMT

Hi,

I need some help in automating sftp.

I have searched this forum and there are numerous threads on this topic but it pertains to OpenVMS.

I am running HP-UX 11.23.

I have tried putting the password in a batch file and executing sftp with '-b' option but it doesn't seem to work - it always prompts for password. =(

Does anyone know how to make it work?

Thanks in advance

I am not sure about sftp, I know you can automate using scp. Following is the procedure.

On source server, generate public and private keys.

/usr/bin/ssh-keygen -t rsa
/usr/bin/ssh-agent $SHELL
/usr/bin/ssh-add

Just keep hitting return key.

On the Destnation Server

mkdir $HOME/.ssh
chmod 700 $HOME/.ssh

From Source Server to Dest

scp $HOME/.ssh/id_rsa.pub Dest_Server_IP:$HOME/.ssh/id_rsa.pub_Source_Server

On Dest Server

cat $HOME/.ssh/id_rsa.pub_Source_Server >> $HOME/.ssh/authorized_keys

You are done.

Cheers,
Ravi.

Hi,

After following the above procedure, I just found that sftp hostname is not asking any password.

Have you arranged the key files for SSH
access without a password? (Why not?)

Normally, SSH, SCP, SFTP, Sxxx are used when
one does not wish to specify a password
interactively. (And there should be any
number of Forum threads related to setting up
SSH access without using a password, for
practically every OS.)

Hi,

If you configure your server SSH without passwd it will automaticly configure for all S* like SSH, SCP, SFTP, so just configre the above things and do sftp without passwd.

Hi all,

Thanks for all your replies.

With regards to setting SSH access without password, is it an "all or nothing" setting? In other words, is it a global setting in that once set without password, all access will be without password or can it be set such that some users will not be prompted while some will?

Regards

It can be done per host ("hostbased") or per
user ("publickey"). Find some appropriate
SSH documentation. As I suggested before, a
Forum search should lead to some. (I could
do it for you, but you'll learn more this
way.)

Each user can set it as he pleases. Assuming you mean from UserA to UserA on different machines.
You can also set it up so a user doesn't have to enter a passphrase at all (a generic account), to being required at least once.
There may be configuration settings that may disallow some of these?
