How to view blocklist logs

[MartyTng]

I have installed 2.42 from source on my TonidoPlug (debian-based). I connect to it with Transmission Remote on Windows. I believe I have a blocklist working, but am not sure how to verify. Is there any way to log the blocks?

[rb07]

No.

All you'll ever see in the log (/var/log/messages usually) is when the daemon starts there's a message about how many 'rules' the loaded blocklist contains.

But Transmission-Qt shows the same thing in the Preferences->Privacy (when running with a remote session), doesn't Transmission-Remote do the same?

set message level to 3

/var/log/messages

then you'll see things like:

<31>Jan 30 09:23:49 transmission-daemon[2586]: Found 2 blocklists in "/root/.config/transmission-daemon/blocklists" (session.c:2238)
<30>Jan 30 09:23:49 transmission-daemon[2586]: Blocklist "blocklist.bin" contains 223890 entries (blocklist.c:115)

Thanks for the leads on blocklist messages! When I looked at handshake bug a few weeks ago I didn't bother to look at the blocklist message output. But anyway, attached is patch against r13203 that logs the: torrent, all blockslist blocks, whether they are incoming or outgoing, and all bad piece blocks. If you think I missed any type of the blocks let me know.

patch for advanced Blocklist logging attached.

??? can't seem upload attachment so get it here:

also x190, I don't use tr_dbg for daemon, I use tr_ndbg

here is an example that I have in use for help with my watch directory.

}



ps. read the book "thinking in pictures", it's a great read...

Is there any way to get this information without actually changing source and recompiling? I'm new to Linux, and am surprised I even got the code compiled and working on my TonidoPlug. I get the feeling that I would break something if I tried to re-compile.

The meaning of "set message level to 3" is change settings.json (following the recommended procedure in the Wiki), the key is very similar: "message-level"

Okay. I found and changed the setting to 3. I don't see anything regarding a blocklist or banned IPs in the messages file yet though, even after running "pkill -HUP transmission-da", and "/etc/init.d/transmission-daemon stop" and "/etc/init.d/transmission-daemon start". I do see other things getting logged though. I'll keep an eye on it. Thanks.

You have to stop the daemon before editing settings.json or your changes will be overwritten. You should see your blocklist entries (number of ranges) in the log, but only occasionally an Incoming or banned (bad pieces) block. Outgoing blocks (the vast majority) are not logged, hence the do-it-yourself code above if you want that information.

I did stop and restart the daemon before editing the settings.json file. I am now getting lots of details in the "messages" file, but the word 'banned' or 'blocklist' is not in the 500kb of the file. I guess it's possible that there were no incoming blocks, but I really wish I could see some so I feel safer! In Transmission Remote, I do see the option saying "Blocklist enabled" is checked, and there is an "update" button. This grays out for a moment, but then comes back with no status update.

[MartyTng]

Still no luck seeing anything in the log file about the blocklist being loaded or anything getting blocked. This is one of those things that make me want to run back to Windows!

MartyTng: Did you update the blocklist after you got the URL into the settings? Using the web client you just do:

(the little wrench icon) edit preferences --> peers tab --> [x] enable blocklist then
[_______UPDATE_______]


wait a few minutes and you should see 'Blocklist has xxxxxx rules' on this dialog.

Yes, I am able to do that, but I am not certain that this is actually blocking anything.

[MartyTng]

Blocklist has xxxxxx rules

And in your log:

2012-03-04 15:31:38 -0700 blocklist.c:114 [Info] Transmission: Blocklist "blocklist.bin" contains xxxxxx entries

If you see these entries, then you can be sure that those address ranges are being blocked for peer connections.

I have the "blocklist has 'xxxx' rules" on the screen, but still nothing about a blocklist in /var/log/messages.

Is there somewhere else that my log file(s) could be? I do also see the following files in "/var/log", but the dates are older.
"messages.1"
"messages2.gz"
"messages3.gz"
"messages4.gz"
