- I don't see anything in the PostgreSQL or Tomcat logs suggesting anything is wrong... I think the solution to clear these idle connections is probably to just restart Tomcat
|
||||
- I looked at the Solr stats for this month and see lots of suspicious IPs:

```
|
||||
|
||||
- And a bunch more... ugh...
|
||||
- 70.32.90.172: scraping REST API for IWMI/WLE pages with no user agent
|
||||
- 2a01:7e00::f03c:91ff:fe16:fcb: Linode, REST API, no user agent
|
||||
- 2607:f298:5:101d:f816:3eff:fed9:a484: DreamHost, XMLUI and REST API, python-requests/2.18.4
|
||||
- 2a00:1768:2001:7a::20: Netherlands, XMLUI, trying SQL injections
|
||||
- I need to start blocking requests without a user agent...
|
||||
- I purged these user agents using my `check-spider-ip-hits.sh` script:
|
||||
|
||||
```
|
||||
$ for year in {2010..2019}; do ./check-spider-ip-hits.sh -f /tmp/ips -s statistics-$year -p; done
|
||||
$ ./check-spider-ip-hits.sh -f /tmp/ips -s statistics -p
|
||||
```
|
||||
- Then I added a few of them to the bot mapping in the nginx config because it appears they are regular harvesters since 2018
|
||||
- Looking through the Solr stats faceted by the `userAgent` field I see some interesting ones:
|
||||
|
||||
```
|
||||
$ curl 'http://localhost:8081/solr/statistics/select?q=*%3A*&rows=0&wt=json&indent=true&facet=true&facet.field=userAgent'
|
||||
...
|
||||
"Delphi 2009",50725,
|
||||
"OgScrper/1.0.0",12421,
|
||||
```
|
||||
|
||||
- Delphi is only used by IP addresses in Greece, so that's obviously the GARDIAN people harvesting us...
|
||||
- I have no idea what OgScrper is, but it's not a user!
|
||||
- Then there are 276,000 hits from `MEL-API` from Jordanian IPs in 2018, so that's obviously CodeObia guys...
|
||||
- Other user agents:
|
||||
- GigablastOpenSource/1
|
||||
- Owlin Domain Resolver V1
|
||||
- API scraper
|
||||
- MetaURI
|
||||
- I don't know why, but my `check-spider-hits.sh` script doesn't seem to be handling the user agents with spaces properly so I will delete those manually after
|
||||
- First delete the ones without spaces, creating a temp file in `/tmp/agents` containing the patterns:
|
||||
|
||||
```
|
||||
$ for year in {2010..2019}; do ./check-spider-hits.sh -f /tmp/agents -s statistics-$year -p; done
|
||||
$ ./check-spider-hits.sh -f /tmp/agents -s statistics -p
|
||||
```
|
||||
- That's about 300,000 hits purged...
|
||||
- Then remove the ones with spaces manually, checking the query syntax first, then deleting in yearly cores and the statistics core:
|
||||
|
||||
```
|
||||
$ curl -s "http://localhost:8081/solr/statistics/select" -d "q=userAgent:/Delphi 2009/&rows=0"
|
||||
...
|
||||
<lst name="responseHeader"><int name="status">0</int><int name="QTime">52</int><lst name="params"><str name="q">userAgent:/Delphi 2009/</str><str name="rows">0</str></lst></lst><result name="response" numFound="38760" start="0"></result>
|
||||
$ for year in {2010..2019}; do curl -s "http://localhost:8081/solr/statistics-$year/update?softCommit=true" -H "Content-Type: text/xml" --data-binary '<delete><query>userAgent:"Delphi 2009"</query></delete>'; done
|
||||
$ curl -s "http://localhost:8081/solr/statistics/update?softCommit=true" -H "Content-Type: text/xml" --data-binary '<delete><query>userAgent:"Delphi 2009"</query></delete>'
|
||||
```
|
||||
|
||||
- Quoting them works for now until I can look into it and handle it properly in the script
|
||||
- This was about 400,000 hits in total purged from the Solr statistics
