[comp.protocols.tcp-ip] SVR4 and FTP's software

pjh@mccc.edu (Pete Holsberg) (02/02/91)

It was suggested to me the other day that the POP servers available in
the P.D. and the POP[23] mail software that FTP supplies with PC-TCP
Plus may not work under the TCP/IP support provided with UNIX System V
Release 4.x.  Could an experienced person please try to shed some light
on this?

Thanks,
Pete

PC/TCP only includes POP[23] clients.  There are at least three
freeware POP3 servers available via the Internet, but I believe they
all assume a Berkeley 'sockets' API for TCP.  If your particular SysV
has a reasonably complete 'sockets' implementation, you shouldn't
have any trouble with the network side of the server, but at least
some SysVs only support AT&T's 'streams' API for TCP.  If you have
one of these, you've got some coding to do...

Or, if it's S5R4 and it's one of those, you've got some
yelling-at-the-vendor to do, 'cuz S5R4 systems are *supposed* to come
with a reasonably complete sockets implementation....

I have ported a POP2 server starting from P.D. code to INTEL system V.4
it is not too bad a port: there are still a few minor problems associated
with the mail system rather than the POP daemon itself. 

It is a LOT easier to port BSD/ULtrix code to V.4 thatn it is to V.3 tho.
