In the FileBrowser tool , if you click in Add server you could do some like.

"Please fill in the following info, then select all text and choose DoIt."

    | aa |
    self flag: #ViolateNonReferenceToOtherClasses.
    aa := ServerDirectory new.
    aa server: 'squeakros.org'.    "host"
    aa user: 'xxxx'.
    aa password: 'xxxx'.
    aa directory: '/squeakros.org'.
    aa url: ''.    "<- this is optional.  Only used when *writing* update files."
    ServerDirectory addServer: aa named: 'SqueakRos'.  "<- known by this name in Squeak"

In the attached I add the missing method.
Nice to have how manage a external ftp from inside image, so I share for any which needs.
