Add me to the list of people having the same problem:
root@scanner:~# nc -4vvv thefeedhost 873
nc: connect to thefeedhost port 873 (tcp) failed: Connection refused
root@scanner:~# nc -6vvv thefeedhost 873
Connection to thefeedhost 873 port [tcp/rsync] succeeded!
But nothing after that.
And running the rsync by hand:
root@scanner:~# /usr/bin/rsync -ltvvvvvvvvvvvvvrP --timeout 60 --delete --exclude private/ “rsync://thefeedhost:/nvt-feed” “/var/lib/openvas/plugins”
opening tcp connection to feedhost port 873
Connected to feedhost (2a0e:6b40:20:106:20c:29ff:fe67:cbb5)

root@scanner:~# /usr/bin/rsync -4ltvvvvvvvvvvvvvrP --timeout 160 --delete --exclude private/ “rsync://feedhost:/nvt-feed” “/var/lib/openvas/plugins”
opening tcp connection to feedhost port 873

And one time it almost worked:

The rsync connected and then about 5 minutes later I got the Greenbone message. And then a minute or so later, I got the IO timeout.
And no, there’s no firewall. No NAT. No ACLs. I have full IPv6 connectivity. Anywhere where I’ve put “thefeedhost” I had to redact the feed hostname to make the forum software happy.
