Is there a way to select an ipv4 connection in SyncTerm? I
recently encountered an address that doesn't have ipv6 and
there was a problem connecting.

your OS' network stack should try IPv6 first and then drop back to IPv4 if there's no IPv6 available for that destination domain... that's provided that the domain has both AAAA and A records...

Run syncterm with the "-4" option. This might only work with the 1.1 beta (current).

Do you know how I might be able to accomplish this in Linux (Debian)?
It's possible that the domain doesn't have both those records as a ping
showed the IPv6 address than a IPv4 address. There is another sub-
domain name he mentioned and it showed the IPv4 address and I was able
to connect to it just fine.

beta (current).

Adding -4 as a parameter when running SyncTerm just popped up a help
screen (in terminal mode) without launching the actual program. However,
yeah, I'm running v0.9.5b currently. I'll see if I can grab the 1.1 beta version for Linux (if it's available).

Looks like v1.0 had that feature too: https://sourceforge.net/projects/syncterm/files/syncterm/syncterm-1.0/syncterm- 1.0.tgz/download

that's provided that the domain has both AAAA and A records...

AFAIK, it is built into all current network stacks... it is automatic...

It's possible that the domain doesn't have both those records as a
ping showed the IPv6 address than a IPv4 address.

if they only have a A record, then they only offer IPv4 on that domain...
if they only have an AAAA record, then they only offer IPv6 on that domain... if they have both, then they offer both on that domain...

that's the nature of the beast(s)...

There is another sub-domain name he mentioned and it showed the IPv4 address and I was able to connect to it just fine.

that sounds proper...

That's how it all worked for me.

if they only have a A record, then they only offer IPv4 on that
domain... if they only have an AAAA record, then they only offer IPv6
on that domain... if they have both, then they offer both on that domain...

Yep, that's how it's supposed to work, and usually does. Only time there's trouble is when someone's borked the setup and the service in question is actually not working on IPv6. Had that with a government website, which was borked on IPv6. Had to put an entry in my hosts file to force IPv4 operation.

There is another sub-domain name he mentioned and it showed the IPv4 address and I was able to connect to it just fine.

that sounds proper...

Common practice, I've done it myself.

Yeah, I don't think it has anything to do at a remote end...

I guess I'll have to use the other sub-domain name for now...

well, it could if it is misconfigured DNS records... but the connection flow from your end should be your network stack looking first for an AAAA record and
then for an A record on that domain... if you tell the domain(s) in question, one can dig them and see what's going on...

sounds like... especially if it is not misconfigured but is actually proper for
their setup and how they are configuring their end to respond...
