Linode has been sending mails a few times a day recently that CGSpace (linode18) has had high CPU usage
|
|
Today these are the top 10 IPs:
|
|
|
|
|
|
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "03/Nov/2018" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10
|
|
1300 66.249.64.63
|
|
1384 35.237.175.180
|
|
1430 138.201.52.218
|
|
1455 207.46.13.156
|
|
1500 40.77.167.175
|
|
1979 50.116.102.77
|
|
2790 66.249.64.61
|
|
3367 84.38.130.177
|
|
4537 70.32.83.92
|
|
22508 66.249.64.59
|
|
|
|
|
|
|
|
The 66.249.64.x are definitely Google
|
|
70.32.83.92 is well known, probably CCAFS or something, as it’s only a few thousand requests and always to REST API
|
|
84.38.130.177 is some new IP in Latvia that is only hitting the XMLUI, using the following user agent:
|
|
|
|
|
|
Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.792.0 Safari/535.1
|
|
|
|
|
|
|
|
They at least seem to be re-using their Tomcat sessions:
|
|
|
|
|
|
$ grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=84.38.130.177' dspace.log.2018-11-03 | sort | uniq
|
|
342
|
|
|
|
|
|
|
|
50.116.102.77 is also a regular REST API user
|
|
40.77.167.175 and 207.46.13.156 seem to be Bing
|
|
138.201.52.218 seems to be on Hetzner in Germany, but is using this user agent:
|
|
|
|
|
|
Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:62.0) Gecko/20100101 Firefox/62.0
|
|
|
|
|
|
|
|
And it doesn’t seem they are re-using their Tomcat sessions:
|
|
|
|
|
|
$ grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=138.201.52.218' dspace.log.2018-11-03 | sort | uniq
|
|
1243
|
|
|
|
|
|
|
|
Ah, we’ve apparently seen this server exactly a year ago in 2017-11, making 40,000 requests in one day…
|
|
I wonder if it’s worth adding them to the list of bots in the nginx config?
