Troubleshooting

Request Error -5

RequestError: Failure establishing ssh session: -5, Unable to exchange encryption keys while requesting...

Solution:

Try and upgrade to Julia 1.9.4. It seems to be a bug in an underlying library.

If it does not work, check your known_hosts file in your .ssh directory. ED25519 keys do not seem to work.

Use the ssh-keyscan tool:

From command line, execute: ssh-keyscan [hostname]. Add the ecdsa-sha2-nistp256 line to your known_hosts file. This file is located in your .ssh directory. This is directory is located in C:\Users\{your_user}\.ssh on Windows and ~/.ssh on Linux and Mac.

Note: Setting up certificate authentication

To set up certificate authentication, create the certificates in the ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub files. On Windows these are located in C:\Users\{your user}\.ssh.

Then use the function sftp = SFTP("sftp://mysitewhereIhaveACertificate.com", "myuser") to create a SFTP type.

Example files

known_hosts:

mysitewhereIhaveACertificate.com ssh-rsa sdsadxcvacvljsdflsajflasjdfasldjfsdlfjsldfj

id_rsa:

-----BEGIN RSA PRIVATE KEY-----
.....
cu1sTszTVkP5/rL3CbI+9rgsuCwM67k3DiH4JGOzQpMThPvolCg=

-----END RSA PRIVATE KEY-----

id_rsa.pub:

ssh-rsa AAAAB3...SpjX/4t Comment here

After setting up the files, test using your local sftp client:

ssh myuser@mysitewhereIhaveACertificate.com
