rmfakecloud

This is a replacement of the cloud, in case you want to sync/backup your files and have full control of the hosting environment.

Docs

NB

for SW 3.15 STORAGE_URL should not be set (or only https://some.ho.st without a port should be used)

The current release of rmfakecloud support file synchronization for SW <= 3.14.1. Newer releases have not been tested yet.

For Tablet SW > 3.X, rendering of the notebooks is not yet supported.

Breaking Changes

• after v0.0.3 the files in /data will have to be manually moved to the user that will be created
• with v0.0.5 the new diff sync15 is added as an option, in order to use it modify the user with setuser -u user -s
  or modify the profile and add sync15:true
  a full resync will be needed (the tablet will do it), the old files are kept as they were and everything is put in a new directory

Development

run ./dev.sh which should start the UI and backend

Caveats/ WARNING

• (applies when you don't have security, version <= 0.0.3) connecting to the api will delete all your files, unless you mark them as not synced synced:false prior to syncing (advisable just to disconnect, reconnect the cloud)
• if you delete files from the users directory on the host, on the next sync those will be deleted from the device
• if you delete the whole user directory (by mistake) on the host, you should disconnect the cloud from the device and reconnect it
• after an official update, the proxy and hosts file changes will be removed, the tablet will automatically disconnect from the cloud (by sending an invalid token to the official cloud and getting 403) just reinstall the proxy and reconnect to your cloud

Troubleshooting

• check the connectivity between the tablet and the host: ping my.remarkable.com (should be localhost) ping local.remarkable.com (should be localhost) ping thehostpc wget -qO- http://host:3000 (or relevant ports, should get Working...) wget -qO- https://local.appspot.com (should get Working...)

• check that the proxy is running and certs are installed:

  echo Q | openssl s_client -connect localhost:443  -verify_hostname local.appspot.com -CAfile /etc/ssl/certs/ca-certificates.crt 2>&1 | grep Verify
  

  You should see: Verify return code: 0 (ok)

• if both (host and tablet) are on a wifi make sure "Client Isolation" is not activated on the AP

• check if the proxy is configured correctly

  systemctl status proxy
  
  #or
  
  journalctl -u proxy
  

• check whether the CA cert was installed correctly when doing update-ca-certificates there should have been 1 added check the logs

• check xochitls's logs, stop the service, start manually with more logging

  systemctl stop xochitl
  QT_LOGGING_RULES=rm.network.*=true xochitl | grep -A3 QUrl
  
  

  if you see SSL Handshake failed then something is wrong with the certs

• check sync logs

  journalctl -u rm-sync
