Message 1970468 - Posted: 15 Dec 2018, 13:43:42 UTC

I am using Ubuntu 18.04 as host machine for BOINC (SETI@Home). As there are other important processes running on this machine i want to protect it with firewall. Now the problem is I was not able to upload data to SETI servers with ufw (Uncomplicated Firewall) enabled.
To investigate the ports utilised by BOINC I did a "netstat -antup" and they were 31416 & 41564. So I opened both ports in firewall settings but still unable to upload the data back to SETI servers. Is there some other port utilised ? or some other settings required to run BOINC(SETI@Home) behind a firewall ?

Port 31416 is for communication between BOINC its parts (client, BOINC Manager GUI, boinccmd etc.). For internet connections you have to allow internet connections TCP ports 80 and 443.

80 & 443 are already open as there is a web server running.

Which may be taking up those ports exclusively.

What you can do is post a message log from BOINC with the <http_debug> flag enabled in cc_config.xml

For that, use a standard ASCII editor and write into it:
<cc_config>
<log_flags>
<http_debug>1</http_debug>
</log_flags>

Save as cc_config.xml, ANSI format. Make sure the file doesn't get an extra extension like .txt
Save the file in your data directory. You can check in the start-up messages (BOINC Manager, press CTRL+SHIFT+E to open the Event Log) where that is.

When saved, do BOINC Manager, Options, Read config files.
Next do BOINC Manager, Projects, Select Seti@Home, Update.
Then back to the Event Log and copy & paste the whole output starting with [http]
You can select part of the log by clicking a line, holding SHIFT and clicking the last line, then click Copy Selected.

80 & 443 are already open as there is a web server running.
BOINC (the client only) needs those ports open only for outgoing requests and replies.

Your web server will be listening for incoming traffic on the ports.

Your immediate problem is much more basic:

HTTP error: Couldn't resolve host name
That's a DNS problem, not a port problem.

Sorry, my experience is with Windows, not Linux. Somebody else will have to go through the common DNS scenarios with you.

But working with Windows servers in the past (mainly for corporate internal email, rather than as web servers), they relied on using internal DNS servers for LAN traffic: the internal DNS had to be explicitly configured with - a 'forwarder', I think it was called - to resolve external addresses. Maybe you need to allow DNS through the firewall?

DNS requests go through Port 53 in UFW. Open that port and it should be able to resolve setiboincdata.ssl.berkeley.edu.
sudo ufw allow out 53
