use
	announce("tcp!*!9877", adir)
because /sys/src/9/port/devip.c is misinterpreting
the ip address as a port number (note that your ip address starts with 143!).
i was a bit confused because my own copy of the source has this fixed/changed
for some reason (perhaps it came with beto's multicast changes).
by using "*" in the host part, cs will produce just the port
number for announce to give to the driver.
i don't think the documentation makes it clear.

 When I use announce:

announce("tcp!143.106.24.121!9877", adir);

term% netstat

tcp 0     nojento    Listen  143  0   0.0.0.0

The question is: Why the port used is always 143? Because with this
problem, I have to use dial ("tcp!143.106.24.121!143", 0, devdir, 0).
And
this problem is extended to sockets: I have a program, that use sockets,

that works on Linux and don't work on Plan 9. Because:

server: socket() - bind() - listen() - accept() - read() - write() -
read() - close()
client:                                          socket()  - connect()
-write() - read - close()

    The client have to connect to server, and it's don't occur.
