sftp/ftp failure from LINUX to Windows

[skt_skt]

Red Hat Enterprise Linux AS release 4 (Nahant Update 6)
source is a LINUX one and target is window machine and the public key from LINUX user is provided to import the key to get trutsed.

Not sure why it is failing. Any one has any suggetions??

As you should know, there are some non printable characters that are different on Unix and Windows, specially the LF|CR/LF for a file.

Maybe, you key file is encoded with Windows charset, and that is why you get:

debug2: key_type_from_name: unknown key type '----'
debug3: key_read: missing keytype
debug2: key_type_from_name: unknown key type 'Comment:'
debug3: key_read: missing keytype
debug3: key_read: missing whitespace
debug3: key_read: missing whitespace
debug3: key_read: missing whitespace
debug2: key_type_from_name: unknown key type '----'
debug3: key_read: missing keytype

You can use cat -e to check if you see a ^M at the end of each line.

Shalom,

Services on the windows boxes APPEAR to be working.

Have you checked the event logs on Windows, and/or restarted the services.

Source? Target? Is the Linux system the
client? Is the Windows system the server?

Where was the key created? Where was it
imported? How?

Looks as if the key file format could be bad.
There are two popular SSH key file formats
(OpenSSH, SSH2), and if you have the wrong
one, then you'll need to convert it before
you can use it.

If I could see any of the key files, I might
be able to say more. You could try
generating test key files on each system to
see if they have the same format or not.

If you're using OpenSSH on the HP-UX system,
then conversion to SSH2 format may not have
been the best thing to do.

[Steven Schweda]

Or the Linux system. (Whatever.)

[Ivan Ferreira]

Use cat -e

[Steven Schweda]

Also, we just needed to see the key file
format, not all the key data. You might wish
to throw that key away, and get a new one.

Sounds bad to me.

"debug1: Connecting to 12.166.37.243 [12.166.37.243] port 22.
debug1: Connection established.
"

does the above message enoughg to say the connection was reaching till the windows server. Unfortnatly the windows remote team does not see any hit from my source server in the log.
