But, the ip_masq_ftp module doesn't keep the command channel from timing
out. And, with the default timeouts on tcp connections, this means that you
can't transfer more than 1.5MB over a 28.8 PPP line without losing the
having ftp hang after the transfer. (Big problem for things like netscape,
that delete the downloaded file in this case.) You have to extend the tcp
timeout to do any useful ftping on a slow link.
