Connection error with ssh and pem file (FSCrawler)

[Doddy_Joel (Doddy Castillo Caicedo)]

I'm using FSCrawler by @dadoonet and I'm trying to connect directory with ssh. I have ssh configured on my server so I can access a directory and use FSCrawler. The steps I have followed are as follows:

1. Create a public and private key with the following command (sizes I've used are 2048 and 4086):
   ssh-keygen -t rsa -b 2048 -C sshserver@gtsi -f sshGTSI

2. I have passed the private key to pem format with the following command:
   ssh-keygen -e -p -f sshGTSI -m pem.

3. I have added the public key to the server (ubuntu) in the file ~/.ssh/authorized_keys.

4. In this step I have followed the instructions in the documentation to be able to configure ssh with pem file. The main idea of ​​the use of public and private keys is to avoid the use of passwords, so I think that in the documentation part of ssh together with pem file there would be a small error. If I follow the instructions in the documentation it connects correctly but if I remove the password option I get an authentication error.

I tested the current ssh configuration in my terminal with the following command: ssh -i sshGTSI.pem userserver@#ipserver -p 22 the connection was successful

I have used two versions of the FSCrawler (2.10 and 2.9)
