Hi all,

We are new using Secure Shell to connect to our AIX boxes. Currently FTP is till enabled but in the near future it will be disabled and all FTP transcactions must be done via SFTP (Secure FTP). Does anyone know how this works from the command line? I tried the same format as FTP (ie sftp <boxname>) but it doesn't work.

Thanks!

If you server is configured for SSH then you need to create KEYS (public and private) for each machine between which FTP is required.
do man ssh-keygen

for additional details, see openssh.org.

HTH

I run the sftp command in a script is appears to run without error but the actual file is not ftp'd.... any ideas what would be causing that?

Thanks in advance!!

try changing permisssion 755 for your home directory at remote machine.

If not then try running ftp from command prompt instead from script and post the results

try including -v option to sftp.
this should write to standard output information on connection, authentication or configuration issues.

hope this helps

First thanks for the tips! I verified the permissions on the target directory are set appropriately. I started from scratch and have gotten it to work, however, I had to create two separate files to make this work. Ie.

sendfile.sh contains:

sftp -B up.txt

up.txt contains:

open psadmin@psbhvt2b
ascii
cd sshtest
put mj.txt
quit

Is there any way of getting this to run using only one script? Everytime I try to run the following it does not work:

/apps/ssh2/bin/sftp2 psadmin@psbhvt2b << marker
ascii
cd /home/psadmin
put mj
bye
marker

Here is the verbose output:

The error I hightlighted in red above does not appear be causing the problem since I am using the same ssh/sftp command in the first set of scripts.

Any help would be greatly appreciated!!!
