"https://myownsynologyadress.de/caldav/

https: means you have a certificate for that address and have configured MMM-Caldav to run in secure mode

is that true?

typically one uses mmm-caldav to read from the foreign calendar, and emit ics data for the local machine

and make it available thru a url request (which causes the MMM-Caldav module to provide the data live)

http://mmIP:mmPort/caldav

or shorthand for this same system is (using the default mm port)

http://localhost:8080/caldav

depending on how MM is configured,
address: and ipWhitelist, by default it rejects ALL requests from OUTSIDE systems
so your loop back at - https://myownsynologyadress.de would be rejected…

I use cloudflare to map outside requests to my systems thr a tunnel, so I have https (cert provided by cloudflare) and have reconfigured my MagicMirror to allow any incoming request

address: "0.0.0.0",
ipWhitelist:[],

@sdetweil im running the “container manager” on the nas and the container by bastilimbach installation guide by https://mariushosting.com/how-to-install-magicmirror-on-your-synology-nas/

caw

@sdetweil i used ipv64 to receive a certificate - but for now i dont want to get any caldav from outside or do i missunderstand something?

sdetweil

@caw said in MMM-CalDAV:

bastilimbach

that image is 4 years old, so not running the latest node or MM…

the install doc https://docs.magicmirror.builders/getting-started/installation.html#alternative-installation-methods
references this docker image
https://gitlab.com/khassel/magicmirror

sdetweil

@caw because the ics generated by MMM-Caldav is only needed on this same machine I would use

http://localhost:mmport/CALDAV

in the calendar module.

I am guessing your cert is connected to your internet IP address (ISP router)
which is then port forwarded to the MM machine…

this is an external (from MM’s perspective) request

MM is configured (be default) to be a closed system on the wall, not allowing any external systems to request the MM page (external means outside the machine MM is running on)

@sdetweil i searched for a guide to get the Khassel container running on a Synology NAS but didn’t found anything about it. I tried it by my own but did not work. Do you have a clue how to get it on the Docker on a Synology NAS?

sdetweil

@caw my older 416j only has 512mb storage, not enough room to run docker things

but docker is docker. i thought he specified a compose or command line

see this
https://forum.magicmirror.builders/topic/18952/docker-install-on-synology-nas

@sdetweil @MMRIZE

so i got the khassel image running and i think the calendars are found but i get an error:

[2024-09-05 22:42:56.488] [ERROR] Error: EACCES: permission denied, open ‘/opt/magic_mirror/modules/MMM-CalDAV/service/.SYNOLOGY_Familien_20Kalender.ics’
2024/09/05 22:42:56 stderr [2024-09-05 22:42:56.486] [ERROR] Whoops! There was an uncaught exception…

do you have a clue how to fix this? im irritated by the “20” between Familien_20Kalender.ics thats no part of the calendar name…

sdetweil

@caw 20 is typically part of a name with a space in it, %20

also you have a . (dot) in front of SYNOLOGY_

caw

@sdetweil

and do you have any clue where the misstake is? and how can i fix it?

sdetweil

@caw i am going to guess

remove the dot in front of SYNOLOGY
and in the MagicMirror config mke sure there is a space where you see the 20, or make it %20

one change at a time

caw

@sdetweil i dont have a dot in front of the Prefix

i dont know what caldav wants in its setup,
sorry. you’ll have to wait for @MMRIZE to help

@caw

[ERROR] Error: EACCES: permission denied, open ‘/opt/magic_mirror/modules/MMM-CalDAV/service/.SYNOLOGY_Simon.ics’

I’m not familiar with the Docker setting. Anyway, it seems to be a permission issue. The docker container creation and execution might be performed by different accounts. Or you may need proper permission for those files or directories. However, I have no idea of Docker environment, so that’s all I can say.

@caw

[ERROR] Error: EACCES: permission denied, open ‘/opt/magic_mirror/modules/MMM-CalDAV/service/.SYNOLOGY_Simon.ics’

how did you start the container? Please provide full docker run ... command or compose file.

danny607

Hello, I am new and wondering what do you name the file env.example to? Second What lines need to be added to the /config/config.js file?
Thanks

sdetweil

@danny607 the env file name is typically
.env

note the leading dot

the linux file systems do not have a flag for hidden, so by convention anything with a leading . (dot) will not be shown in file lists unless explicitly requested

sdetweil

@caw

so looking at the code, this module will write out the constructed ICAL format data to

  const filePath = path.resolve(__dirname, 'service', '.' + fileName)

notice the dot… in linux =by convention, file/folder names that start with dot are not shown unless explicitly requested… (making them hidden ‘most’ of the time

SO, the code above is trying to USE a directory ‘service’ (part of this module repo)
in THIS module folder… but write to it…

@karsten13 is the docker volume for where modules are located mapped read/write?? (the compose file doesn’t say)

see docs

rw: Read and write access. This is the default if none is specified.

sdetweil

@karsten13 thats what I thought

@caw can you ssh logon to your synology and execute a docker command

docker inspect  magicmirror

scroll up to look at the mounts section
(this is from a different container, as I don’t have one running MM)

            {

            },

also, how (from where, as what userid?) did you git clone the module, and npm install?

another docker command

docker exec magicmirror ls /opt/magic_mirror/modules -laF
