- Start a harvest on AReS
## 2023-01-16
- Batch import four IFPRI items for CGIAR Initiative on Low-Emission Food Systems
- Batch import another twenty-eight items for IFPRI across several Initiatives
- On this one I did quite a bit of extra work to check for CRPs and data/code URLs in the acknowledgements, licenses, volume/issue/extent, etc
- I fixed some authors, an ISBN, and added extra AGROVOC keywords from the abstracts
- Then I checked for duplicates and ran it through csv-metadata-quality to make sure the countries/regions matched and there were no duplicate metadata values
## 2023-01-17
- Batch import another twenty-three items for IFPRI across several Initiatives
- I checked the IFPRI eBrary for extra CRPs and data/code URLs in the acknowledgements, licenses, volume/issue/extent, etc
- I fixed some authors, an ISBN, and added extra AGROVOC keywords from the abstracts
- Then I found and removed one duplicate in these items, as well as another on CGSpace already (!): 10568/126669
- Then I ran it through csv-metadata-quality to make sure the countries/regions matched and there were no duplicate metadata values
- I exported the Initiatives collection to check the mappings, regions, and other metadata with csv-metadata-quality
- I also added a bunch of ORCID identifiers to my list and tagged 837 new metadata values on CGSpace
- There is a high load on CGSpace pretty regularly
- Looking at Munin it shows there is a marked increase in DSpace sessions the last few weeks:
![DSpace sessions year](/cgspace-notes/2023/01/jmx_dspace_sessions-year.png)
- Is this attributable to all the PRMS harvesting?
- I also see some PostgreSQL locks starting earlier today:
![PostgreSQL locks day](/cgspace-notes/2023/01/postgres_connections_ALL-day.png)
- I'm curious to see what kinds of IPs have been connecting, so I will look at the last few weeks:
```console
# zcat --force /var/log/nginx/{rest,access,library-access,oai}.log /var/log/nginx/{rest,access,library-access,oai}.log.1 /var/log/nginx/{rest,access,library-access,oai}.log.{2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25}.gz | awk '{print $1}' | sort | uniq > /tmp/2023-01-17-cgspace-ips.txt
# wc -l /tmp/2023-01-17-cgspace-ips.txt
129446 /tmp/2023-01-17-cgspace-ips.txt
```
- I ran the IPs through my `resolve-addresses-geoip2.py` script to resolve their ASNs/networks, then extracted some lists of data center ISPs by eyeballing them (Amazon, Google, Microsoft, Apple, DigitalOcean, HostRoyale, and a dozen others):
```console
$ csvgrep -c asn -r '^(8075|714|16276|15169|23576|24940|13238|32934|14061|12876|55286|203020|204287|7922|50245|6939|16509|14618)$' \
/tmp/2023-01-17-cgspace-ips.csv | csvcut -c network | \
sed 1d | sort | uniq > /tmp/networks-to-block.txt
$ wc -l /tmp/networks-to-block.txt
776 /tmp/networks-to-block.txt
```
- I added the list of networks to nginx's `bot-networks.conf` so they will all be heavily rate limited
- Looking at the Munin stats again I see the load has been extra high since yesterday morning:
![CPU week](/cgspace-notes/2023/01/cpu-week.png)
- But still, it's suspicious that there are so many PostgreSQL locks
- Looking at the Solr stats to check the hits the last month (actually I skipped December because I was so busy)
- I see 31.148.223.10 is on ALFA TELECOM s.r.o. in Russia and it made 43,000 requests this month (and 400,000 more last month!)
- I see 18.203.245.60 is on Amazon and it uses weird user agents, different with each request
- I see 3.249.192.212 is on Amazon and it uses weird user agents, different with each request
- I see 34.244.160.145 is on Amazon and it uses weird user agents, different with each request
- I see 52.213.59.101 is on Amazon and it uses weird user agents, different with each request
- I see 91.209.8.29 is in Bulgaria on DGM EOOD and is low risk according to Scamlytics, but their user agent is all lower case and it's a data center ISP so nope
- I see 54.78.176.127 is on Amazon and it uses weird user agents, different with each request
- I see 54.246.128.111 is on Amazon and it uses weird user agents, different with each request
- I see 54.74.197.53 is on Amazon and it uses weird user agents, different with each request
- I see 52.16.103.133 is on Amazon and it uses weird user agents, different with each request
- I see 63.32.99.252 is on Amazon and it uses weird user agents, different with each request
- I see 176.34.141.181 is on Amazon and it uses weird user agents, different with each request
- I see 34.243.17.80 is on Amazon and it uses weird user agents, different with each request
- I see 34.240.206.16 is on Amazon and it uses weird user agents, different with each request
- I see 18.203.81.120 is on Amazon and it uses weird user agents, different with each request
- I see 176.97.210.106 is on Tube Hosting and is rate VERY BAD, malicious, scammy on everything I checked
- I see 79.110.73.54 is on ALFA TELCOM / Serverel and is using a different, weird user agent with each request
- There are too many to count... so I will purge these and then move on to user agents
- I purged hits from those IPs:
```console
$ ./ilri/check-spider-ip-hits.sh -f /tmp/ips.txt -p
Purging 439185 hits from 31.148.223.10 in statistics

```
- Looking at user agents in Solr statistics from 2022-12 and 2023-01 I see some weird ones:
- `azure-logic-apps/1.0 (workflow e1f855704d6543f48be6205c40f4083f; version 08585300079823949478) microsoft-flow/1.0`
- `Gov employment data scraper ([[your email]])`
- `Microsoft.Data.Mashup (https://go.microsoft.com/fwlink/?LinkID=304225)`
- `crownpeak`
- `Mozilla/5.0 (compatible)`
- Also, a ton of them are lower case, which I've never seen before... it might be possible, but looks super fishy to me:
- `mozilla/5.0 (x11; ubuntu; linux x86_64; rv:84.0) gecko/20100101 firefox/86.0`
- `mozilla/5.0 (macintosh; intel mac os x 11_3) applewebkit/537.36 (khtml, like gecko) chrome/89.0.4389.90 safari/537.36`
- `mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/86.0.4240.75 safari/537.36`
- `mozilla/5.0 (windows nt 10.0; win64; x64; rv:86.0) gecko/20100101 firefox/86.0`
- `mozilla/5.0 (x11; linux x86_64) applewebkit/537.36 (khtml, like gecko) chrome/90.0.4430.93 safari/537.36`
- `mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/92.0.4515.159 safari/537.36`
- `mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/88.0.4324.104 safari/537.36`
- `mozilla/5.0 (x11; linux x86_64) applewebkit/537.36 (khtml, like gecko) chrome/86.0.4240.75 safari/537.36`
- I purged some of those:
```console
$ ./ilri/check-spider-hits.sh -f /tmp/agents.txt -p
Purging 1658 hits from azure-logic-apps\/1.0 in statistics
Purging 948 hits from Gov employment data scraper in statistics
Purging 786 hits from Microsoft\.Data\.Mashup in statistics
Purging 303 hits from crownpeak in statistics
Purging 332 hits from Mozilla\/5.0 (compatible) in statistics
Total number of bot hits purged: 4027
```
- Then I ran all system updates on the server and rebooted it
- Hopefully this clears the locks and the nginx mitigation helps with the load from non-human hosts in large data centers
- I need to re-work how I'm doing this whitelisting and blacklisting... it's way too complicated now
- Export entire CGSpace to check Initiative mappings, and add nineteen...
- Start a harvest on AReS
