High Sierra 10.13.2 and Fetch 5.7.7 (6 posts)

    Greetings,
    Since updating our MAC users to High Sierra 10.13.2 and then updating their Fetch application to 5.7.7, they are receiving the error “no matching cipher found. Their offer: aes256-cbc…”
    I read your post about how some macOS Sierra (not High Sierra) users receiving a similar error of “no matching host key type found. Their offer: ssh-dss” when using a SFTP connection.

    I've verified with the connection host that nothing changed on their end. I attempted to delete the .ssh file on one of our MACs in hopes that it would delete\recreate the .ssh host file, but still receive the same error. I also read that Fetch 5.7 should handle any mismatch.

    I tried the same SFTP connection on a macbook Pro with a fresh install of the latest version of Fetch with no success, same error

    I tested the same SFTP connection settings on a PC using the FileZilla application and the connection was successful.

    I believe that either the security protocol/keys changed on Fetch's end or on macOS High Sierra's end, when my users updated.
    I don't know how I would go about modifying (if even possible) on their MACs.

    Can you help?

    Thanks

    Hi,

    Apple has tightened security in Sierra and then again in High Sierra, dropping default support for some SSH ciphers and key types that are considered vulnerable (FileZilla still works because it isn't as picky). The real fix for this issue is for the server to be updated to use stronger cryptography, but if that isn't possible you can configure macOS to re-enable the deprecated options when you connect to certain servers. For details please contact me at https://fetchsoftworks.com/fetch/feedback and send along the name of the server.

    Thanks,

    Hi There,

    I am experiencing the same problem. I am trying to access my clients server to share files, they keep telling me its my firewall. I obviously can't tell my client to update their servers, so I need to find a fix on my side.

    Thanks!

    Hi,

    That's a keychain error; Fetch and some other applications have started getting that error in 10.13. Please do the following to check for and repair problems with the keychain:

    * Quit Fetch, if it's running.
    * In the Finder, choose Utilities from the Go menu
    * Open the Disk Utility application
    * Select the startup disk in the list on the left
    * Click the "First Aid" button, and then the Run button
    * Once it's done, try Fetch again.

    Let us know if you're still having problems after doing this.

    Thanks,
