Hey all--I'm experiencing increasing delays in resolving the hostname when I connect to my board and I'm curious if anyone has any tips on how I can clear them up.
I'm currently having SBBS restart services after a user logs
off (and checking that no other users are logged in). Here's the rest of how I have it set up:
-A domain from GoDaddy with a DNS record pointing to,
-A hosted Ubuntu VPS serving as a static IP that leads to,
-A reverse SSH tunnel from a Win 10 32-bit VM to the VPS
If I try to sign on right after signing off, the board responds immediately. The longer the board goes without a call, the longer the hostname resolution takes. Regardless of final resolution time, I get the initial Synchronet version statement at the top of the screen right away.
Are you sure it's hostname lookup that's taking time? If you disable hostname lookups in the Terminal Server, does the delay go away?
What the size of your text/host.can and text/*ip.can files?
There's a Synchronet version statement upon initial connect and before hostname lookup:
Synchronet BBS for Win32 Version 3.21
Telnet connection from: 2600:6c88:8c40:5b::14e
Resolving hostname...

Yeah, this is where the delay gets longer and longer.
An extra note.
Whenever I connect, the "Telnet connection from:" always shows as "::1"
That's weird. Doesn't seem like a Synchronet issue, to be honest.Yeah, I wasn't sure. It's just weird that the delay happens only after I see the initial Synchronet version stamp. The delay seems to still be present even with hostname lookup disabled. I re-enabled it. I'm still trying to figure out why the delay goes away after I restart the board's services.
::1 is the IPv6 address of localhost/loopback (IPv4 127.0.0.1).I'm very puzzled by this, especially since I'm connecting through a domain routed to a hosted VPS, which only then is making it to my home network. Regardless, I may try to confirm all IPv6 stuff is disabled everywhere (I thought I already had).

Hey DM--thanks as always for your time and help.

I believe it's the hostname lookup. I disabled it just a minute ago and will monitor it.

what the fuck. why are you doing that.

Why am I doing what? Using a domain with my bbs? lol.. Silly question.
what you mean is 'only then is making it to my home network"
