Connection to SSH Server

Hi, 

I'm not sure I understand how to use the PrivateKey File Path setting properly for the "SSH Connection Scope" activity.  I have set up an Open SSH file with the private RSA key for the desired linux server connection, however I'm not sure how to reference the needed password in order for the key to get utilized.  How do I input a password for the connected Open SSH file so that my key can be decrypted?  

Error occuring for missing passphrase:  

Source: SSH Connect Scope

Message: Private key is encrypted but passphrase is empty.

Exception Type: Renci.SshNet.Common.SshPassPhraseNullOrEmptyException

Hello Sorin,

Good evening.

1. Could you please correct the "SSHTimeout_Description" in your resources file (Resources.resx). The description says "Specifies the amount of time (in milliseconds) to wait for the SSH  specific activity to run before an error is thrown. The default value is  30000 (1 minute)."

2. Could you please tell why SSH session is getting disconnected when SSHConnectActivity and SSHRunShellCommandActivity are in two separate workflows ?.

 

Currently, the workflow corresponding to SSHRunShellCommandActivity is getting invoked inside SSHConnectActivity. I was expecting that SSH Session will be shared in this case too, but somehow getting errors.

Note: If both these activites are in same workflow, then everything goes fine.

Hello Sorin,

Good evening.

Can you please share the documentation of SSHRunShellCommandActivity. It seems the user guide (under resources) doesn't have any reference of the above activity.

Is there a character limitation built into the Response status?  The responses I'm getting back truncate to a "..."

Is there a way to get more detail back either from a setting in the activity/package, or perhaps a global setting for UiPath?

Dear Sorin,

I posted before and now I could connect without problem Thanks for the reply. Now I am trying to execute the "cd test" command to switch to "test" directory and then use "ls" to get the list of files and directories, but the "cd" command has not worked. It keeps in the root directory. Please Help.

Dear Sorin,

I made a free ssh account at https://sdf.org/ to test your component. Apparently the SSH Connect Scope works, but when I tried to run a command (already tried with SSH Run Command and SSH Run Shel Command), an error raises "One or more errors occurred". 

I already tested this connection from PUTTY and works perfectly. At the beginning when I enter my password it  gaves me the next message and I press backspace so then I can execute any command

Please press your BACKSPACE key:

Please help, I need this working and your component seems to be the solution but I need to figure out how to execute a basic command like ls.

Hi Sorin,

I tried to connect to one of my Linux servers. But whenever I am trying to use the SSH connect activity it is throwing the error like this: SSH Connect Scope: One or more errors occurred. Kindly help me out in this matter. 

Thank You,

Hi Sorin, 

I tried SSH connect scope on server A and within the scope I gave ssh command "pwd" in Run SHH Comand activity. I am getting below error, can you please help?

In connection I kept proxy setting blank and mentioned only all SSH settings.

Error:

SSH Connect Scope: Server response does not contain SSH protocol identification.

Hi,

I have my UiPath Studio in local machine and i need to run PuTTy in RDP. Will this activity work? Local machine does not have access to the host which needs to be connected to via SSH the access is only in the RDP. 

Thanks in advance.

Hi Sorin

I have installed SSH.NET >= 2016.1.0 package but I am unable to see 2 activities: SSHConnectScopeActivity and SSHRunCommandActivity.

I checked under Team also.. No luck..
