Sync DAVx5 CALDAV Client Cache to Xadikos #178

I had installed CALDAV server (Radicale) on my old laptop, but now I don't have access to that machine. I had synced calendars hosted by the caldav server to my android using DAVx5.

Now, on my new machine I have installed a CALDAV server (Xandikos), and I would like to sync the existing CALDAV calendars on Android that were synced to Radicale be synced to Xandikos.

Essentially the base url of each calendar needs to be updated, from http://192.168.178.22:5232/nikhil to http://192.168.178.33:8899/users/calendars.

Any suggestions?

Steps that I tried

I created folder mkdir -p /Users/lamyergeier/dav/nikhil/calendars
I launched Xadikos with 192.168.178.22 and port 5232: /Users/lamyergeier/.local/bin/xandikos -d /Users/lamyergeier/dav -l 192.168.178.22 -p 5232

Observation

On the browser http://192.168.178.22:5232 doesn't load the web interface! and it shows Firefox can’t establish a connection to the server at 192.168.178.22:5232.

The question about DAV5X is probably best asked in a DAV5X forum. Let's focus on the fact that you can't actually reach Xandikos here.

What output do you get from Xandikos itself? Does it say it's listening on http://192.168.178.22:5232/ ? Can you reach http://192.168.178.22:5232/ using e.g. curl on the machine where you're running Xandikos.

@jelmer I was wondering that since the CALDAV server uses 2 way sync, I could simply sync from the client (DAVx5) by making the base URL of the calendars in the client same as that on the Xandikos server.

It looks like there's probably already something listening on that port. Radicale perhaps?

That could work, but calendars in Xandikos are git repositories so you'll need to create those using git rather than using mkdir.

@jelmer I started xandikos using ip /Users/lamyergeier/.local/bin/xandikos -d /Users/lamyergeier/dav -l 192.168.178.33 -p 5232

Can you please tell me how can I check that which process is listening on IP 192.168.178.33? By this I can check the process listening on 192.168.178.22.

I don't have Radicale installed anymore as I don't have that machine. As per my estimation this IP address should be free.

I tried

lsof -i 4tcp
netstat

but they don't show the IP on which Xandikos is listening!

"netstat -lp" might help you on unix machines - but this is really an OS-specific question than related to Xandikos.

@jelmer Thank you! I have now connected xandikos to the same IP and port to which the radicale was connected on the old device.

My directory structure is as follows

$ pwd
/Users/lamyergeier/dav
$ tree
.
├── nikhil
│   └── calendars
└── user
    ├── calendars
    ├── contacts
    └── inbox

6 directories, 0 files

I am trying to sync from DAVx5 but nithing sync's and I get the following error:

INFO:aiohttp.access:192.168.178.21 [08/Jul/2022:17:49:10 +0000] "PROPFIND /nikhil/6229e809-b885-b85b-d83a-a799bfa7040e/ HTTP/1.1" 207 387 "-" "DAVx5/4.2.1-ose (2022/05/08; dav4jvm; okhttp/4.9.3) Android/11"

Here,

6229e809-b885-b85b-d83a-a799bfa7040e is the calendar folder name.
192.168.178.21 is the IP address of Android

About the Web interface

Even though I have created folder users and nikhil under the base folder, the web interface just shows user, the default principal!

Why is it not showing nikhil as well? Also, why the two way sync not working?

Also, as far as I understand git is not mandatory for the functioning of CALDAV server right? That's only needed when we want to log changes to history. So, it should not be an issue.

You need to tell Xandikos what you want the principal to be; pass in --current-user-principal=/nikhil/

Thanks I did this. The calendars are not yet synced, but I get the following log 2 lines for each calendar

Have you actually created the calendar on the xandikos side with git?
