TRAMP provides several ways to flush remote connections.
This command flushes all connection related objects. vec is the internal representation of a remote connection. When called interactively, this command lists active remote connections in the minibuffer. Each connection is of the format /method:user@host:.
Flushing remote connections also cleans the password cache (see Reusing passwords for several connections), file cache, connection cache (see Reusing connection related information), and recentf cache. It also deletes session timers (see Setting own connection related information) and connection buffers.
If keep-debug is non-nil, the debug buffer is kept. A
non-nil keep-password preserves the password cache.
Flushes the current buffer’s remote connection objects, the same as in
tramp-cleanup-connection.
Flushes all active remote connection objects, the same as in
tramp-cleanup-connection. This command removes also ad-hoc
proxy definitions (see Declaring multiple hops in the file name).
Just as for tramp-cleanup-all-connections, all remote
connections and ad-hoc proxy definition are cleaned up in addition to
killing all buffers related to remote connections.
