CGSpace Notes

2019-09-01

• Linode emailed to say that CGSpace (linode18) had a high rate of outbound traffic for several hours this morning

• Here are the top ten IPs in the nginx XMLUI and REST/OAI logs this morning:

  # zcat --force /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep -E "01/Sep/2019:0" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10
  440 17.58.101.255
  441 157.55.39.101
  485 207.46.13.43
  728 169.60.128.125
  730 207.46.13.108
  758 157.55.39.9
  808 66.160.140.179
  814 207.46.13.212
  2472 163.172.71.23
  6092 3.94.211.189
  # zcat --force /var/log/nginx/rest.log /var/log/nginx/rest.log.1 /var/log/nginx/oai.log /var/log/nginx/oai.log.1 | grep -E "01/Sep/2019:0" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10
   33 2a01:7e00::f03c:91ff:fe16:fcb
   57 3.83.192.124
   57 3.87.77.25
   57 54.82.1.8
  822 2a01:9cc0:47:1:1a:4:0:2
  1223 45.5.184.72
  1633 172.104.229.92
  5112 205.186.128.185
  7249 2a01:7e00::f03c:91ff:fe18:7396
  9124 45.5.186.2
  

• 3.94.211.189 is MauiBot, and most of its requests are to Discovery and get rate limited with HTTP 503

• 163.172.71.23 is some IP on Online SAS in France and its user agent is:

  Mozilla/5.0 ((Windows; U; Windows NT 6.1; fr; rv:1.9.2) Gecko/20100115 Firefox/3.6)
  

• It actually got mostly HTTP 200 responses:

  # zcat --force /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep -E "01/Sep/2019:0" | grep 163.172.71.23 | awk '{print $9}' | sort | uniq -c
  1775 200
  703 499
   72 503
  

• And it was mostly requesting Discover pages:

  # zcat --force /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep -E "01/Sep/2019:0" | grep 163.172.71.23 | grep -o -E "(bitstream|discover|handle)" | sort | uniq -c 
  2350 discover
   71 handle
  

• I’m not sure why the outbound traffic rate was so high…

• Follow up with Carol and Francesca from Bioversity as they were on holiday during the mid-to-late August
  • I told them to check the temporary collection on DSpace Test where I uploaded the 1,427 items so they can see how it will look
  • Also, I told them to advise me about the strange file extensions (.7z, .zip, .lck)
  • Also, I reminded Abenet to check the metadata, as the institutional authors at least will need some modification
