How to Create an SSH Connection Based on Public/Private Keys Pair

To create a Secure Shell (SSH) connection based on a public/private keys pair, perform the following steps:

Search for	Example	Results
A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

Open the Mindterm console (on the probe machine) and from the command line run following command:

C:\hp\UCMDB\DataFlowProbe\bin\jre\bin\java.exe -jar C:\hp\UCMDB\DataFlowProbe\content\lib\Mindterm.jar

In the Mindterm console, go to File > Create Keypair and assign the following values:

Key type/format: choose DSA or RSA
Key length:
- If Key type/format = DSA: choose 1024
- If Key type/format = RSA: choose one of the following: 768, 1024, 1536, 2048, 4096, 8192, 16384 or 32768
Identity file: assign a name (the default name is identity)
Password: for no password, do not enter anything

Caution The OpenSSH .pub format option must be selected.

Click Generate and move your mouse to generate public/private keys.

Once the pair is generated, go to C:\Users\<username>\AppData\Roaming\MindTerm. This directory contains generated public/private keys pair. The public key has the .pub extension.

Copy the contents of .pub file to the remote Linux/Unix machine you want to connect to as follows:

Connect to the Linux/Unix remote machine and locate the ~/.ssh/authorized_keys file (if the file does not exist, create it).
Open the file for editing as follows:
```
vi ~/.ssh/authorized_keys
```
Append the contents of the .pub file to the authorized_keys file.
Add <username>@<probe IP> to the end of the contents of the .pub file. For example, if the contents of the .pub file are:
```
ssh-dss AAAAB3N.....<snippet>.....r2LnQrqhncpJyL1s0id76j6wA==
```
and the probe's IP is 16.59.56.255 and the username to connect with is root, you would append the following to the contents of the ~/.ssh/authorized_keys file:
```
ssh-dss AAAAB3N.....<snippet>.....r2LnQrqhncpJyL1s0id76j6wA== root@16.59.56.255
```
Save the ~/.ssh/authorized_keys file and close it.

Open the UCMDB and go to Data Flow Management > Data Flow Probe Setup > Credentials > SSH Protocol.

Add a new SSH protocol with the following parameters:

Authentication Method: publickey
User Name: root
Key File Path: C:\\Users\\<username>\\AppData\\Roaming\\MindTerm\\<identity file>, where <identity file> is the name you entered in step 2.
Password: if you provided a password during creation of the public/private keys pair, you must enter the same password here.
