I use mainly FreeBSD, and it contains /usr/ports/net/latd, which sort
of works. I say sort of, since there are some fairly big warts there.
Major nits are:
* When you start latd, it *refuses* to use an interface that does
not have an IPv4 address assigned. Obviously there is a need for
an IPv4 address to be assigned on an interface intended to be used
for a different protocol.... NOT!
* The concept of taking characters typed on the keyboard and sending
them unmolested to the other end is apparently alien to some.
Putting llogin in a wrapper like:
#!/bin/sh
save_state=$(stty -g)
stty raw
stty cs7
llogin -c $1
stty "$save_state"
sort of solves that issue.
* llogin should drop to a command handler like telnet does upon
receipt of its break character, instead of terminating itself.
* Speaking of break, it should NOT turn the NULL character into
the aforementioned break function (OOB function in LAT), but
rather pass it thru and let the command level mentioned above
provide the means of sending a break if that is ever needed.
Apart from that it sort of works.
