Environment:

Product: LoadMaster

Version: Any

Platform: Any

Application: SFTP

Question/Problem Description:

Automated SFTP backups not working.

Steps to Reproduce:  
Error Message: Automated Backup to x.x.x.x (sftp) returned 255 "Unable to negotiate with x.x.x.x port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1 Connection closed. Connection closed "
Defect Number:  
Enhancement Number:  
Cause: These logs indicate that the LoadMaster doesn't have a matching cipher with the SFTP/SCP server. The ciphers are noted in the log message under the "Their offer" portion.
Resolution: If possible, expand the list of ciphers available on the server.  Recommend the use of https://www.puttygen.com/ to generate the SSH keys using SSH-2 RSA with 2048 bit key size.
