Putty PPK files

[Lee Pedley]

Hi,

I am trying to setup a private key file on Bots, and cannot get it to connect.  I am not sure if the private key side needs to be in a certain file format, but it comes up with;

  File "/usr/local/lib/python2.7/site-packages/paramiko/sftp_client.py", line 165, in from_transport window_size=window_size, max_packet_size=max_packet_size File "/usr/local/lib/python2.7/site-packages/paramiko/transport.py", line 924, in open_session timeout=timeout, File "/usr/local/lib/python2.7/site-packages/paramiko/transport.py", line 1051, in open_channel raise e EOFError

Looking at the ppk file which is created by Puttygen, it does include a lot of other lines in here, so not sure if I just need to cut this down to a pure RSA file and remove the comments or what?

Anyone have any ideas?

The file has these lines;

PuTTY-User-Key-File-3: ssh-rsa
Encryption: none
Comment: rsa-key-20240605
Public-Lines: 6

Private-Lines: 14

Private-MAC:

Thanks

Lee

It looks like you are trying to use it to connect to an SFTP server (so via SSH). In this case, the private key would need to be converted to an OpenSSH format.

Hi tom,

Thanks this is correct I am using SFTP (SSH).  Will give this a go, thank you so much for coming back to me.  All new to this type of connection.

I will let you know how I get on.

Have a great day.

Hi,

I tried that and its still the same error, the timeouts mentioned, appear that it is trying and the session does take a long time each time it runs, so I am guessing it is trying to connect.

I have tried to connect locally from the same machine using the same private key and can do this, so I know this is possible, it's purely down to bots I guess. I have confirmed with them and the address is whitelisted, plus with the ability to log on direct from command line I guess confirms this.

line 924, in open_session timeout=timeout,

Not sure which way to of wit this now.

Thanks for your help

Hi Lee,

did you use the export function in puttygen to openSSH?

then in the channel add the location of the openssh key file in  'Private key file:' like "botssys/Privkey.cer"

and add a communicationscript with has the secret 

def privatekey(channeldict):
return channeldict['keyfile'],'RSA','password' #in channel, path to private key; type of key file, password for key file 

this should work.
