+\S2{using-cmdline-loghost} \i\c{-loghost}: specify a \i{logical host
+name}
+
+This option overrides PuTTY's normal SSH host key caching policy by
+telling it the name of the host you expect your connection to end up
+at (in cases where this differs from the location PuTTY thinks it's
+connecting to). It can be a plain host name, or a host name followed
+by a colon and a port number. See \k{config-loghost} for more detail
+on this.
