passwordless sftp from Windows to Unix is not working

Hi,

 

We want to set up a passwordless sftp from Winodws to Unix For this we have performed the below actions

 

1) We are using a FTP client called Attachmate for genenrating the keys and for sftp

2) The keys  which generated from that utility is added in  Unix machine succesfully

3) The password less SFTP  using the utility is working fine

4) But   while i am doing sftp from the windows command prompt its asking for password

 

99% its an issue with Windows side . But could you please have a thought on this.

 

Regards

Does the Windows side allow you to add the -vvv option?

Does it work going from HP-UX to Windows?

Hi Dennis,

 

I am attaching the output of sftp -vvv option.

 

We are trying to connect from windows to HPUX

It looks truncated?

Yes but does the other way work?  Or you haven't set up the keys for the reverse?

Re: passwordless sftp from Windows to Unix is not working

At the beginning of output, the sftp client seems to be reading its configuration file:

2013-02-08 15:26:26:996 debug1: Reading configuration settings from C:\Users\p.c
onsy.03\Documents\Attachmate\Reflection\.ssh\config.
2013-02-08 15:26:26:997 debug1: Invalid host section: Host sgsing2k8pdb01
2013-02-08 15:26:26:997 debug1: Ignoring config line:     IdentityFile "C:\Users
\p.consy.03\Documents\Attachmate\Reflection\.ssh\id_DSA_1024_SGSINGM2K8PDB01_a"
2013-02-08 15:26:26:997 debug1: Invalid host section: Host hpux82c

 

I guess it's trying to find a Host section in the configuration file that would exactly match the hostname you're trying to connect to. Apparently you've used the short form ("hpux82c") in the configuration file.

 

2013-02-08 15:26:27:000 debug1: Host: hpux82c.ey.com not found in configuration
file C:\Users\p.consy.03\Documents\Attachmate\Reflection\.ssh\config

 

The FTP client "thinks" that hpux82c.ey.com is not the same as hpux82c, so it is not applying any of the Host sections. So it will not know which identity file (also known as "the SSH private key") to use.

 

Possible solutions:

  • try connecting using the short hostname:
C:\Users\p.consy.03>sftp -vvv dapa01p@hpux82c
  •  or add this section to the configuration file C:\Users\p.c onsy.03\Documents\Attachmate\Reflection\.ssh\config:
Host hpux82c.ey.com
    IdentityFile "C:\Users\p.consy.03\Documents\Attachmate\Reflection\.ssh\id_DSA_1024_SGSINGM2K8PDB01_a"
    PreferredAuthentications publickey

Re: passwordless sftp from Windows to Unix is not working

Hi Amol,

 

We are not handling any thing in attachmate configuration .  In our scenario this is the responsibility of windows to team configure attachmate and generate the keys .

Our responsiblity is to just put the keys in the Unix server .
