|

- I started a harvest on AReS and it finished in a few hours now that the load on CGSpace is back to a normal level

## 2021-07-20
|
||||
|
||||
- Looking again at the IPs making connections to CGSpace over the last few days from these seven ASNs, it's much higher than I noticed yesterday:
|
||||
|
||||
```console
|
||||
$ csvgrep -c asn -r '^(49453|46844|206485|62282|36352|35913|35624)$' /tmp/out.csv | csvcut -c ip | sed 1d | sort | uniq | wc -l
|
||||
5643
|
||||
```
|
||||
|
||||
- I purged 27,000 more hits from the Solr stats using this new list of IPs with my `check-spider-ip-hits.sh` script
|
||||
- Surprise surprise, I checked the nginx logs from 2021-06-23 when we last had issues with thousands of XMLUI sessions and PostgreSQL connections and I see IPs from the same ASNs!
|
||||
|
||||
```console
|
||||
$ sudo zcat --force /var/log/nginx/access.log.27.gz /var/log/nginx/access.log.28.gz | grep -E " (200|499) " | grep -v -E "(mahider|Googlebot|Turnitin|Grammarly|Unpaywall|UptimeRobot|bot)" | awk '{print $1}' | sort | uniq > /tmp/all-ips-june-23.txt
|
||||
$ ./ilri/resolve-addresses-geoip2.py -i /tmp/all-ips-june-23.txt -o /tmp/out.csv
|
||||
$ csvcut -c 2,4 /tmp/out.csv | sed 1d | sort | uniq -c | sort -n | tail -n 15

```
|
||||
|
||||
- Again it was over 5,000 IPs:
|
||||
|
||||
```console
|
||||
$ csvgrep -c asn -r '^(49453|46844|206485|62282|36352|35913|35624)$' /tmp/out.csv | csvcut -c ip | sed 1d | sort | uniq | wc -l
|
||||
5228
|
||||
```
|
||||
|
||||
- Interestingly, it seems these are five thousand *different* IP addresses than the attack from last weekend, as there are over 10,000 unique ones if I combine them!
|
||||
|
||||
```console
|
||||
$ cat /tmp/ips-june23.txt /tmp/ips-jul16.txt | sort | uniq | wc -l
|
||||
10458
|
||||
```
|
||||
|
||||
- I purged all the (26,000) hits from these new IP addresses from Solr as well

<li><a href="https://github.com/ilri/OpenRXV/issues/103">Hide “metadata structure” section in repository setup</a></li>
|

<li>Rebuild DSpace Test (linode26) from a fresh Ubuntu 20.04 image on Linode</li>
|

<li>The start plugins on AReS had seventy-five errors from the <code>dspace_add_missing_items</code> plugin for some reason so I had to start a fresh indexing</li>
|

<li>I noticed that the WorldFish data has dozens of incorrect countries so I should talk to Salem about that because they manage it
|

<ul>
|
||||
<li>Also I noticed that we weren’t using the Country formatter in OpenRXV for the WorldFish country field, so some values don’t get mapped properly</li>
|
||||
<li>I added some value mappings to fix some issues with WorldFish data and added a few more fields to the repository harvesting config and started a fresh re-indexing</li>
