Re: SFTP Options

I wanted to update this for the archives, and to thank everyone who
responded. The issue was trying to use sFTP from System i to a UNIX
box. The problem is that the System i uses OpenSSH, and the UNIX box
was using SSH2. The keys are incompatible, so I needed to convert one
key format to the other. Here's the fix:

If their publickeys look like this:
---- BEGIN SSH2 PUBLIC KEY ----
Comment: "rsa-key-20060601"
AAAAB3NzaC1yc2EAAAABJQAAAIBXGYhxfsIKI0LT7N6CyP3kcQnb6IeXFmK+AhCE
6j2ownI64PuTnVzcbY8Ipr4pl8q/W4dmQq/cQwOlPtyY3KJtMrKyqlfdg5nV0OF2
Upjx/myuRf+qRWAD8Je4Ws4O2JPKAGZT4bd+yH0whFGN/UzmOuhawNd5nHDimEK5
nfIFrQ==
---- END SSH2 PUBLIC KEY ----
then they are not OpenSSH format and need to convert to Openssh.

To convert an SSH2 format to an OpenSSH format .
ssh-keygen -i -f SSH2_format_publickey_file > OpenSSH_format_publickey_file
To convert an OpenSSH format publickey to SSH2 format:
ssh-keygen -e -f OpenSSH_format_publickey_file > SSH2_format_publickey_file

Sigh...losing my mind with SFTP from an iSeries to a Unix box. My
Tectia client PC accesses the Unix box fine - I'm not able to make it
work from the iSeries. I've been trying to use an unattended using
information from:
Document Number: 386077821
Functional Area: Communications-TCP
Subfunctional Area: Security
Sub-Subfunctional Area: OpenSSH
OS/400 Release: V5R3M0
Product: PORTABLE UTILITIES FOR I5/OS (5733SC101)
Product Release: N/A

But no joy. Right now I'd just like to make a connection to the Unix
box manually. Any one get this to work recently - attended or
unattended? Any hints?

Thanks...
