OpenSSH 4.1

[teqmem]

I apologize if posted this on the wrong forum but I'm testing on AIX.

I now run OpenSSH 3.9P1 on all our servers. I use the command 'sftp -b' with expect scripts to transfer files among the servers in the background. With OpenSSH 3.9P1, I don't have any problems.

I noticed that new versions of OpenSSH and OpenSSL just became available. I downloaded and installed but I'm running into a problem that hopefully you can help me.

When I run 'sftp' without the '-b', I can connect to a remote host. When I run 'sftp' with '-b', I receive a 'Permission Denied' error. 'password' is listed but it doesn't seem to try it. Any ideas? Thanks.



Here's a screen capture. First, I show that I have a script file, then run without the -b successfully, then run with -b.

$ cat t.sftp
cd /tmp
pwd
$
$ sftp dev
Connecting to dev...

sftp> pwd
Remote working directory: /home/cicweb
sftp> quit

$ sftp -v -b t.sftp dev

Since batch mode isn't meant to be an interactive mode, it could be that password authentication has been disabled for the -b prompt.

I'd suggest either moving to a non interactive (key based) authentication or moving the batch script commands into your expect script.
