22.4 - Feed Synchronization - Downloading Vulnerability Tests


i’ve received following error message when performing the sync:

root@xxxxxxxxxxxx:~# sudo -u gvm greenbone-nvt-sync
rsync: [Receiver] failed to connect to feed.community.greenbone.net ( Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(137) [Receiver=3.2.3]

Is there a way to specify the proxy server in the command? I guess, that could be the solution. Or do you know anything else?

Hi @florian.kaiser,

are you still seeing this? If so, do you have more than one instance/connection running?


Yes, I still see that, unfortunately. I have only one connection open.

Cool! (one connection)

I just re-read and saw you are using a proxy. The Community Edition supports direct connection, and might not be connecting due to the proxy.

And don’t forget the feed sync uses rsync instead of http. The port may be blocked in your network.


Also don’t forget that some specific environments / security measures on the network in question might block the usage of rsync in general.

@florian.kaiser you need to open rsync port to that ip address. rsync uses default tcp (or udp) port 873
