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 GSTCP.
1. copy the marignotti, ftp, sic, and whois executables to your /usr/local/bin directory.
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
(a bunch of messages)
:j << join a room
2. copy the services file to /etc/services (if it does not exist).
3. edit and copy the 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 sites.
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 and started Sweet 16 from the terminal (/Applications/, marignotti -d will print some debugging information to the console. marignotti -dd will enable extra debugging information (including the contents of reads and writes).
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(1) 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(2) -- support for FIONREAD (bytes available to read) and FIONBIO (set/clear non-blocking).
getsockopt(2) -- 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.
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
