MariGNOtti is a network driver for GNO/ME 2.0.6. It provides a translation
layer between BSD sockets and Marinetti. Think of it as a replacement for
1. copy the `marignotti`, `ftp`, `sic`, and `whois` executables to your `/usr/local/bin`
* `ftp` is an update of the gno 2.0.6 ftp (it adds passive ftp support).
* `whois` is an updated version (from FreeBSD 9.0). The gno 2.0.6 version is from FreeBSD 2.1.
* `sic` is a very simple irc client.
sic -h -p 6667 -n myname

2. copy the `etc/services` file to `/etc/services` (if it does not exist).
3. edit and copy the `etc/resolve.conf` file to `/etc/resolve.conf` (if it does
not exist). This file is your DNS server
4. If you don't have a DNS server, edit `/etc/hosts` to include your favorite
Run marignotti in the background (`marignotti &`). To quit, bring it to the
foreground (`fg`) and hit `control-C`.
If you're using the Sweet-16 emulator version 3.0, `marignotti -d` will print
some debugging information to the debugger console. `marignotti -dd` will
enable extra debugging information (including the contents of reads and
What it does:
While marignotti is running in the background, it translates BSD socket calls
into Marinetti tool calls. It also handles blocking IO, socket options,
select, etc.
BSD sockets are, by default, blocking whereas everything Marinetti does
(other than the inital network connection) is non-blocking. To handle
blocking behavior, each socket has a semaphore. The main thread performs
all the polling and uses the semaphore to signal the other threads when they
can proceed.
`socket` -- only support for `PF_UNIX`, `SOCK_STREAM`, and `SOCK_DGRAM`.
`connect` -- but non-blocking connects are not yet supported.
`bind` -- currently a no-op since the old `whois` used it.
`read`/`recv`/`recvfrom` -- supports blocking, non-blocking, timeouts, and `RCVLOWAT`.
The address parameter of `recvfrom` is not supported. OOB is not supported.
`write`/`send`/`sendto` -- does not support `SNDLOWAT`, OOB, or the address parameter
of `sendto`.
`close` -- does not support `SOLINGER` type functionality.
`shutdown` -- sets flags but the flags are not completely implemented.
`ioctl` -- support for `FIONREAD` (bytes available to read) and `FIONBIO`
(set/clear non-blocking).
`getsockopt` -- support for `SO_OOBINLINE`, `SO_SNDLOWAT`, `SO_RCVLOWAT`,
`SO_SNDTIMEO`, `SO_RCVTIMEO`, `SNDLOWAT` and `SNDTIMEO` set flags but don't have any
other effect. `OOBINLINE` is only be supported when true.
`getsockopt` -- support for `SO_TYPE`, `SO_OOBINLINE`, `SO_SNDLOWAT`, `SO_RCVLOWAT`,
Not (yet) supported:
- OOB (out of band) data (and will never be supported).
- raw sockets (`SOCK_RAW`)
- TCP servers (`listen`/`accept`). Should be simple, though.
- UDP servers
