bit quick and dirty, and there may still be errors or confusions present.
* NetBSD does not use tcpd, since inetd does internal checks.
* NetBSD uses hosts_options.
* NetBSD inetd does not have `paranoid' mode to automatically reject
paranoid connections without further processing.
* NetBSD can have more than one address on a physical interface.
* Safe_finger comes from the tcp_wrappers package, not included in NetBSD.
* Add RCS ID (at end, because this uses old manpage macros).
and declare ssir as volatile. This avoids the problem of lost softints
should a hard interrupt cause a softint to be flagged while we are
clearing a different one.
Idea from atari mtpr.h, modified/optimized by me.
* Command line editing via editline(3) library.
* Context sensitive command and file completion, including remote files.
Enhancements to auto-fetch feature:
* Support for http:// URLs using the http protocol, including proxy HTTP
support via $htty_proxy if it's defined.
* The connection is kept open between successive files on the same host.
(obviously, this does not count for http requests.)
* Return value of ftp is 0 on no error, or the offset in argv[] of the file
which failed (i.e., argv[x] failed, ftp returns x).
* If the path in an ftp URL or classic format line has a trailing '/',
cd to the path and enter interactive mode. Fixes [bin/3011], albiet
requiring the user to help ftp in determining the operation.
Other changes:
* '-P port' works for normal ftp, and is the default for all classic style
auto-fetch transfers and for ftp URLs that don't specify the port.
(previously it would just work for the first xfer.)
* Some code moved into separated files along logical divisions.
* Editing and completion can be compiled out with -DSMALLFTP.
cute little trick where the zs interrupts are enabled as soon as the
zs driver has done its attachments. That allows a console break to
enter the debugger during the rest of autoconfiguration.
