Can you give me ideas on how to improve my code generation service
<https://github.com/Ebenezer-group/onwards>
? FreeBSD's motto is "the power to serve." The back tier of my service
runs on FreeBSD. The middle tier is a UDP server, and my front tier is
a small, highly portable program. The service is free so I don't think
that can be improved on, but if you want to get into the code, that's
good. Maybe you have a suggestion about how to organize things
differently, etc. Thank you in advance.

Currently my code generator is a TCP server. I've been
looking into some alternatives to that. I'd like to use
Wireguard for encryption so something like Quic might not
work for me. I've never used SCTP or DCCP. Would those
work with Wireguard? I need it to work on Posix including
FreeBSD and Linux. Any advice for choosing between SCTP
and DCCP?

I guess DCCP doesn't provide reliable in-order delivery so
that's not an option. I'll try SCTP for now.

I've made a little progress with using SCTP:
https://github.com/Ebenezer-group/onwards/blob/master/src/cmw/tiers/cmwA.cc

. One thing that has eluded me though is figuring out how
to increase the heartbeat interval. From what I can tell
the interval is 30 seconds on both FreeBSD and openSUSE.
I've guessed that you can adjust it via setsockopt and have
searched for sctp and setsockopt, but so far haven't figured
it out. I even tried using something other than Duckduckgo
to search, but that didn't help.

With more people needing quality, free services,
I'm looking for a router that has support for SCTP
in terms of port forwarding. I read on Stackoverflow
that the percentage of routers with SCTP support was
very low as of 2013. Thanks in advance for advice
on this.

SCTP is like IPv6 - it has many clear advantages over its predecessors,
and has been predicted to replace them for nearly 10 years, but is still
seen almost nowhere. Just as IPv6 is only found either on specialised
or highly technical local networks, or tunnelled over IPv4 for wider
networking, SCTP is only found on similar local networks or tunnelled
over UDP.

There are almost no off-the-shelf routers that handle SCTP explicitly
and are sold at a sane price tag. (Of course trunk routers just pass on
the IP traffic without concerning themselves with the protocol inside.)
Windows has no native SCTP support. Thus there are virtually no
applications that support it. Thus there is no incentive for MS to
support it in Windows, and no incentive for makers of small routers to
support it. Rinse and repeat, going around the circles as much as you
want. Chickens and eggs.

The trouble is, while SCTP has many clear advantages over TCP/IP and
UDP, and could replace both of them, in almost all use-cases you can
make either TCP/IP or UDP work well enough. Patching, encapsulating,
workarounds are all lower cost and fewer changes than switching over to
something better.

So while you are right to think that SCTP is a superior technological
choice, you can expect that none of your customers will have any
interest or ability to use it.

Having said that, if you still want a router that is SCTP aware, I think
the best bet is to put one together yourself. My primary suggestions
here are pfSense running on an x86 box (since you like BSD), or OpenWRT
running on practically anything from a cheapo home wireless router to a
powerful rack server. They are both straightforward to install in most
cases.

IPv6 is much more obviously a good idea IMO. We probably shouldn't
start a debate about it here though, and I agree with your point that
relying on either is a bad idea.

Lots of organizations, from Google and Facebook to Debian, are
available over IPv6; the problem is with the ISPs. (The end result
is the same, though -- no IPv6 for most people.)

SCTP is also ok. IPv6 much more usefull though...

Yep, I think this is because they charge premium price for ipv4
addresses...

I'm not sure what you mean about unable to use it. Linux
and FreeBSD support SCTP. I don't need Windows support.

I look forward to your posts here but can't
agree this time. SCTP good. IPv6 bad.

[David Brown]

None of them will be able to connect to your system using SCTP, because
the protocol will not be tracked through the NAT routers that they
(almost invariably) will be using.

If you find I am wrong in this, great. I know a good deal about
networking, but not everything, and I haven't had cause to try SCTP.
You would probably get better more useful help from a newsgroup aimed at
Linux or BSD networking (like comp.os.linux.networking), rather than a
C++ group where the post is off-topic.

[woodb...@gmail.com]

Thanks for the clarification. This article

https://www.networkworld.com/article/2222277/what-about-stream-control-transmission-protocol--sctp--.html

Says:
"Operating systems, applications, and network equipment
all needed to be upgraded to support IPv6 to enable it to
work. SCTP only requires applications and operating system
support, but that is still a daunting task."

I'm hoping the part about "SCTP only requires applications
and operating system support" is true, but am not sure.

Using linux makes a great router.

SCTP is available for Linux.

Raspberry Pi runs Linux.

Some models of Raspberry Pi have WiFi built in
(admittedly with limited range, but should be enough
for a wireless repeater if you need that).

If you need a real network center, couple the Raspberry Pi
with a multilayer managed switch. Cisco SG350-10 is
available on Amazon for $144.

Thanks for your comments. I would probably use FreeBSD
rather than Linux for that.

I'm trying to avoid Amazon. One alternative I've found is https://www.bhphotovideo.com

. Their prices are often better than Amazon's if you have
their card. I should add them to my recommended sites page.

You're welcome. I didn't mean to suggest that Linux is the only
viable choice. I have a fair amount of experience using Linux
(and also other systems) to do routing/networking, and am happy to
recommend it, but FreeBSD (where I have very little experience)
may also be fine.

> I'm trying to avoid Amazon.

I wasn't recommending Amazon, just providing a convenient point of
reference and one that is a known quantity.

> One alternative I've found is https://www.bhphotovideo.com

Great, I will try to take a look.
