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/resolv.conf file to /etc/resolv.conf (if it does
not exist). This file points to your DNS server; update it as needed.
4. If you do not 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 will 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
