- Seems that something happened yesterday afternoon at around 5PM...
|
||||
- For now I will just run all updates on the server and reboot it, as I have no idea what causes this issue
|
||||
- I had to restart Tomcat 7 three times after the server came back up before all Solr statistics cores came up properly
|
||||
- I checked the nginx logs around 5PM yesterday to see who was accessing the server:
|
||||
|
||||
```
|
||||
# cat /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E '04/Aug/2020:(17|18)' | goaccess --log-format=COMBINED -
|
||||
```
|
||||
|
||||
- I see the Macaroni Bros are using their new user agent for harvesting: `RTB website BOT`
|
||||
- But that pattern doesn't match in the nginx bot list or Tomcat's crawler session manager valve because we're only checking for `[Bb]ot`!
|
||||
- So they have created thousands of Tomcat sessions:
|
||||
|
||||
```
|
||||
$ cat dspace.log.2020-08-04 | grep -E "(63.32.242.35|64.62.202.71)" | grep -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
|
||||
5693
|
||||
```
|
||||
|
||||
- DSpace itself uses a case-sensitive regex for user agents so there are no hits from those IPs in Solr, but I need to tweak the other regexes so they don't misuse the resources
|
||||
- Perhaps `[Bb][Oo][Tt]`...
|
||||
- I see another IP 104.198.96.245, which is also using the "RTB website BOT" but there are 70,000 hits in Solr from earlier this year before they started using the user agent
|
||||
- I purged all the hits from Solr, including a few thousand from 64.62.202.71
|
||||
- A few more IPs causing lots of Tomcat sessions yesterday:
|
||||
|
||||
```
|
||||
$ cat dspace.log.2020-08-04 | grep "38.128.66.10" | grep -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
|
||||
1585
|
||||
$ cat dspace.log.2020-08-04 | grep "64.62.202.71" | grep -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
|
||||
5691
|
||||
```
|
||||
|
||||
- 38.128.66.10 isn't creating any Solr statistics due to our DSpace agents pattern, but they are creating lots of sessions so perhaps I need to force them to use one session in Tomcat:
|
||||
|
||||
```
|
||||
Mozilla/5.0 (Windows NT 5.1) brokenlinkcheck.com/1.2
|
||||
```
|
||||
|
||||
- 64.62.202.71 is using a user agent I've never seen before:
|
||||
|
||||
```
|
||||
Mozilla/5.0 (compatible; +centuryb.o.t9[at]gmail.com)
|
||||
```
|
||||
|
||||
- So now our "bot" regex can't even match that...
|
||||
- Unless we change it to `[Bb]\.?[Oo]\.?[Tt]\.?`... which seems to match all variations of "bot" I can think of right now, according to [regexr.com](https://regexr.com/59lpt):
|
||||
|
||||
```
|
||||
RTB website BOT
|
||||
Altmetribot
|
||||
Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
|
||||
Mozilla/5.0 (compatible; +centuryb.o.t9[at]gmail.com)
|
||||
Mozilla/5.0 (compatible; BLEXBot/1.0; +http://webmeup-crawler.com/)
|
||||
```
|
||||
|
||||
- And another IP belonging to Turnitin (the alternate user agent of Turnitinbot):
|
||||
|
||||
```
|
||||
$ cat dspace.log.2020-08-04 | grep "199.47.87.145" | grep -E 'sessi
|
||||
on_id=[A-Z0-9]{32}' | sort | uniq | wc -l
|
||||
2777
|
||||
```
|
||||
|
||||
- I will add `Turnitin` to the Tomcat Crawler Session Manager Valve regex as well...
