pfBlockerNG ASN downloads only contain a header
-
I made some changes to my gist. Pls redownload and see how it goes. Should show a dashboard error on a fail now
-
With 3.2.0_6 I see now this.
[ AS202425_v4 ] Downloading update [ 08/14/23 22:42:23 ] . Downloading ASN: 202425... completed parse error: Invalid numeric literal at line 1, column 10 . completed .. Empty file, Adding '127.1.7.7' to avoid download failure. ------------------------------ Original Master Final ------------------------------ 0 0 0 [ Pass ] -----------------------------------------------------------------Deleting files in /var/db/pfblockerng didn't helped.

Netgate approved my changes a bit early, as I am still waiting on a reply to my support ticket with BGPview/Security Trails/Recorded Future.
The API is probably still blocking the agent string as it contains "pfBlockerNG"
So in the short term, after upgrading to the latest version, re-download the patch that I posted in this thread.
Will keep everyone updated as I can

the version you placed on the test URL for
the first ua assignment
is the old "pfSense/pfBlockerNG .... "
the second one further down is the new
"pfSense/pfBNG.....I didn't see anything appear on the dashboard when it failed but the IP count sure dropped on the dashboard.
Downloading ASN: (masked) ........... completed ..
Empty file, Adding '127.1.7.7' to avoid download failure.I changed the first ua back to pfSense/pfBNG as it was in the previous round of testing and of course it downloaded fine.
I'll leave it until morning and look at it more. -

That's what I have done after update to 3.2.0_6 and everything OK here ...
(The decisive factor seems to be the user agent.) -
So this code works --- I removed the
the check for the "error" strings if the file is html (is not needed IMHO) as the only check needed is that you have successful json file ie:
"Query was successful"you could optionally add an addition look here to see if the file also contains "prefix" as not having any "prefix" in the response would likely imply that they returned an AS the has no IP's associated (not sure that would/could happen) - so that for another day.
I've also changed the grep to only return a "count" -c of the "Query was successful" there should alway only be 1. If the json every came back with more, that would be bad. If the file has 0, it is not that json you expect. Also using count, the entire response string doesn't need to be loaded into the variable (which ultimately saves memory assignment/reassigment)
move the "break" inside the successful part of the if (so the intended retries work) and only break out on success
if [ -e "${asntemp}" ] && [ -s "${asntemp}" ]; then printf "." successful="$(grep -c 'Query was successful' ${asntemp})" if [ ${successful} == 1 ]; then found=true echo ". completed" echo "### AS${asn}: ${host} ###" >> "${pfborig}${alias}.orig" cat "${asntemp}" | "${pathjq}" -r ".data.ipv${_bgp_type}_prefixes[].prefix" >> "${pfborig}${alias}.orig" break else echo ". Failed to download ASN" echo " [ AS${asn}: ${host} ] FAILED to download ASN [ ${now} ]" >> "${errorlog}" touch "${pfborig}${alias}.fail" fi else sleep_val="$((i * 2))" sleep "${sleep_val}" fiwith the the ua="pfSense/pfBlockerNG cURL download agent-"
it now tries the 5 times intended and ends up on the dashboard as intended
the associated trash can does clear the error from the dashboard
the associate pfblockerng.log shows the appropriate reties (and in my case yes I logged the command called ;-) )
Downloading ASN: masked.

Empty file, Adding '127.1.7.7' to avoid download failure.
(this can be fixed so that if the empty file is a result of 5 failed download attempts it doesn't replace it, which may be "better" )so next was to change the ua back to the new (temporary perhaps) norm.
ua="pfSense/pfBNG cURL download agent-"Downloading ASN: (masked).
.. completed
. completed ..which it gets on the first try and the resulting files contain the IPs as expected. All good.
final comment -
the only issue with pfsense/pfBlockerNG is the cookie/javascript request which returns the HTML of the moment.
a "standard" build of curl should have the option to handle the cookie and it would work. The pfSense build of curl isn't dare we say standard (ie is missing these options)
on another box the ua="pfSense/pfBlockerNG .... works just fine, because the cookie is processed.Cheers
Edit -- actually playing with curl on the netgate - the options for it to handle cookies are in fact available on the command line (not in the curl --help) I can create the cookie jar, but for some reason it is not responding to the cookie request like it does on another box. so it might in fact just be a "bug" in the build on Netgate. I'm not going to chase this, and the issue is there should be no cookie response from a json api in the first place. why BGPView is only making the request for "pfSense/pfBlockerNG in the agent string, hope they provide you some insight.
just out of curiosity I changed the ua to "cURL download pfSense/pfBlockerNG agent-" and it works.. so they really just don't want pfSense/pfBlockerNG at the start of the agent string. go figure
-
Another tweak would be to only have it write and update the error if all the attempts fail
currently if try 1,2 3 fail and 4 works (simply because of download issues) there will still be 3 failed attempt in the error file.
which would show on the dashboard,
writing the error and touching the "failed" file only on the 5 and final failure would be appropriateso
echo ". Failed to download ASN" if [ ${i} == 5 ]; then echo " [ AS${asn}: ${host} ] FAILED to download ASN [ ${now} ]" >> "${errorlog}" touch "${pfborig}${alias}.fail" firesulting in one notice and only if all 5 attempts fail.

@manilx said in No ASN shown in reports any longer:
There is a patch mentioned "curl -o /usr/local/pkg/pfblockerng/pfblockerng.sh "https://gist.githubusercontent.com/BBcan177/1c1fee14759bc574350a3bc85b63a57e/raw"
Should I apply this? Run from the pfsense CLI I suppose?
For me, it is still failing with that patch. I guess we have to wait.
-
yes because line 761 in that file is still wrong and then the "if" statement in the raw "patch" just masks the fact.
I had emailed @BBcan177 a patch file that can be applied from system patches, but there has been no response or change thus far.
-
I believe that the "final" patch should come from dev source.
Edit: if you are applying this patch, make sure you set the Path Strip Count and Base Directory as shown in the screen capture.
However, if you install/reinstall 3.0.2_6 and then build a patch as shown below, you will get ASN files that update, dashboard notifications when it doesn't and extra logging to help you determine if/when things go wrong. I've been running this for days without further issue and turned it into a patch file on the 17th

For me it is also not working but I haven't reinstalled pfBlocker. -

Have to correct myself, it is working great. Looks like
you really haveI had to reinstall pfBlocker. Thanks man!

@jrey I had the "Path Strip Count" wrong (2).
Reinstalled pfblocker, applied the patch and all working.Thx!

@Bob-Dig said in pfBlockerNG ASN downloads only contain a header:
really have to reinstall pfBlocker.
you have to start from a clean 3.0.2_6 base, you can just reinstall that, (for clarity not a complete reinstall of pfblockerNG) and do not install the raw file first
just go from fresh 3.0.2_6 directly to the patch.
-
so you had to change it from 2 to 0 as shown in the screen shot I provided :-)

Now second instance is patched, thank you. Problem on first attempt was the original patch that couldn't fix it.
