dbclient: unable to connect to github #140

M95D · 2021-11-24T20:53:03Z

Gentoo Linux, kernel without IPv6, dropbear v2020.81 with debug option.
I can't connect to github. This is the log.

Notice the error: Couldn't set IPV6_TCLASS (Protocol not available)
Is IPv6 required for dropbear client to work?

The text was updated successfully, but these errors were encountered:

mkj · 2021-11-24T22:45:29Z

The IPV6_TCLASS message is just a warning that it can't set priority, it won't close. What is the full commandline or program connecting to github? It looks like github are rejecting it.

I tried adding ipv6 in kernel. I still get the same "Protocol not available" in the debug log. You may be right, but - just to make sure it's not ipv6 - what else do I need to eliminate that error?

What do you get if you just run dbclient git@github.com ?

I get

Hi mkj! You've successfully authenticated, but GitHub does not provide shell access.

This is how it appears on screen. The console is unusable after this, but that's anonther issue.
It's not a key issue. The converted key works fine with openssh.

I don't see why it wouldn't work, I've put in a GitHub ticket #1407998 (I can't CC you)

Hi. Sorry for adding noise! Is there any news from the ticket you sent?

I'm on Alpine with the dbclient shipped by the distro, and I think I've got the same problem with Github. My machine has both IPv6 and IPv4 though.

I tried ssh to other Git services (Gitea, Gitlab), they all work fine with the same key.

Here is the configuration from the Alpine build:

./configure --prefix=/usr --sysconfdir=/etc --mandir=/usr/share/man --infodir=/usr/share/info --localstatedir=/var --disable-wtmp --disable-lastlog

I will try to build a debug binary and get a trace in the next few days.

mkj · 2022-07-31T05:52:07Z

I'll close this, if anyone has further information from Github support please reopen/reply.
