Slow Sunday

This post started as Tired Saturday :

Very late night last night (trying to fix a tv), very late start today.

I've developed a cough. Sean, Mari's Irish friend brought it, Mari got it in the week, now me. Annoying.

Sunday, so I won't feel bad if I don't get much done today.

Plan

  1. Server decommissioning
  2. #FOAFRetrospective stuff
  3. No.7 garden
  4. AI assistant

FOAF Retrospective

danbri's last message about it:

I think for foaf collecting raw materials is key Like the most interesting or impactful things that ever used it Or ongojng use in linkeddata datasets Skos is also kind of needing the same but is probably another story

Server Decommissioning

Previous virtual server on Linode that go compromised. I need to download copies of anything that might potentially be useful.

But the server is in a state of disarray, I can't remember what's where. I'll start by looking at the root directory:

danny@localhost:~$ ls /
bin                boot  etc   lib    lib64              libx32      media  opt   root  sbin                snap  sys  usr
bin.usr-is-merged  dev   home  lib32  lib.usr-is-merged  lost+found  mnt    proc  run   sbin.usr-is-merged  srv   tmp  var

Ok, I guess I should get (most of) :

$du -sh /root
  • /etc - 2.4G
  • /root - 1.9G
  • /home - 3.5G
  • /var - 12GB

Not as big as I expected, but still a pain on this slow connection.

Find my find big files script...

#!/bin/bash
find ./ -type f -printf '%s %p\n' | sort -nr | head -30

Ah. Now I see why /etc is that size. Lots of big files for #Fuseki DBs. I'd better get all that dir.

/root has a lot of big junk. I'll get rid of some of that before getting the dir.

/home - similar. A lot under .git subdirs that should be safe to ditch - similar stuff will already be local and on GitHub

/var - hah, of course - lots of big log files

Now what's the best tar/gzip command...ask ChatGPT...

tar -czvf root_backup.tar.gz /root

(It also had suggestions including scp, but today I'll do it step-by-step)

Ok, that actually looks familiar. So right away I'll do :

mkdir /zips
cd /zips
time tar -czvf server-decommission-2024-05_etc.tar.gz /etc
...
real	1m54.447s
user	1m36.847s
sys	0m12.939s

File size is 364M, that's grand.

Now to copy it down. scp, but I think it's have to be as non-root user. Ok,

chmod -R 777 ./

Overkill, who cares. Locally,

mkdir server-decommission_2024-05
cd server-decommission_2024-05

time scp danny@178.79.136.35:/zips/server-decommission-2024-05_etc.tar.gz ./

Looks to be working. Dogwalk time.

server-decommission-2024-05_etc.tar.gz        100%  363MB 841.7KB/s   07:22

real	7m41.482s
user	0m4.618s
sys	0m7.892s

Good-good. Next, check that's got reasonable contents. Next, clean those other dirs a bit and repeat for them.
