I recently added | the InfCloud integration, which basically is a webclient for | caldav/carddav, hosted within the radicale instance, which is | very nice if you want to check things without your device. | | [1]https://github.com/Unrud/RadicaleInfCloud | girzel wrote: | This is what I've been using, but it appears to be abandoned | now? | | I finally got the caldav part of it to work for a group of | people using various flavors of Mac, Linux, and Windows -- PCs | and phones. It was a huge pain in the ass, because each client | accepted a different form of base-url-plus-calendar-locator, | and some very non-technical users were on the other side of the | planet, and it took weeks of trial and error before we got | everything working. | | Carddav looks hopeless, I can't even something that works | between DavX5 on my android phone, and whatever the hell my | wife's iPhone needs, and we're in the same room. | abawany wrote: | The iphone seems to be very particular about which | caldav/carddav implementations it works with.

I began | using caldav for a similar reason: I'm on Android and my wife is | on iOS, and it annoyed me that Android tries desperately to | standardize you on Gmail and addressbook, while iOS insists you | use iCloud. I like maintaining a degree as independence. | | I'm not as clever as the individual who wrote this useful blog, | but in my case I set up an account with Fruux, who offers vcard | and vcal as a service. It syncs perfectly across several OSes (on | Windows I used eMclient, and on Linux as I mentioned I've | struggled). Anyone who wants to avoid setting up custom servers, | Fruux handles that part easily. | | This afternoon I'll try to see if I can get vdirsyncer and khard | working. I _really_ wish the likes of thunderbird and kmail | offered better carddav and caldav support. Evolution does, but I | 'm not a huge fan of Evolution (and not sure why). | cerberusss wrote: | As far as I know, Android doesn't support CalDAV or CardDAV. | Any apps I tried were lacking in some way or another. How did | you get Android to sync with Fruux? | abawany wrote: | I used DAVx5 from Bitfire (available on F-Droid and the Play | Store) and it works very well. It is able to sync on multiple | devices and from multiple providers. | lorenzfx wrote: | I have been quite happy with https://dmfs.org/caldav/. There | is also a carddav client from the same publisher. | bad_user wrote: | Fastmail also provides syncing of contacts via CardDAV [1]. | | Works great with iOS and MacOS out of the box, never had issues | with it. | | [1]: | https://www.fastmail.com/help/technical/servernamesandports.... | thedanbob wrote: | The only issue I've had with CardDAV on FastMail is a | ridiculously obscure edge case: it doesn't like the ID strings | of rooms on my Matrix server (e.g. | !randomcharacters:example.com -- it strips out the colon and | everything after it). Fortunately, iCloud doesn't mangle them | and and the contacts app on iOS lets you merge contacts from | multiple sources. | floatingatoll wrote: | Have you contacted FastMail support about the | escaping/truncation bug you describe? What was their reply? | thedanbob wrote: | You know, it didn't even occur to me to contact them at the | time since I was able to find a workaround. But that's a | good idea, I'll see what they have to say. | | Edit: looks like they found and fixed the issue on their | own, I just tried it again and it worked. | saagarjha wrote: | > I can no longer sync iOS' Contacts with my macOS Catalina's | Finder | | I'm not sure I understand what this means; how does Finder access | and sync contacts? | philo23 wrote: | The iOS (and iPod) sync portion of iTunes is now built into the | Finder in macOS Catalina, now that iTunes has been split up | into different apps (Music, Podcasts, etc) | deng wrote: | I myself use DAVx^5 with NextCloud for many years and it works | fine. But having written quite a bit of client code for CalDAV, | let me tell you these are really arcane protocols in dire need of | replacement. It's really no fun at all, and I wish "we all" could | move to something a bit more modern (which essentially means: | something more RESTy). I have no idea how this could work, | though... | mercutio2 wrote: | WebDAV is about as RESTy as you're likely to ever see. | Collections containing different resources, different behaviors | based on ContentType, extensible to allow different types of | data. Behavior and state determined by hypertext. | | Usually when people say they don't like CalDAV or CardDAV, they | mean they don't like XML, non-GET verbs, and Versit Consortium | syntax (none of which are in conflict with REST)? | | I'll admit Versit syntax, with it's significant whitespace, | among other warts, is a bit of a pain. | | JMAP is really the same data model as CardDAV and CalDAV, just | with different encodings of everything, if that's what you | want. | pferde wrote: | https://jmap.io/spec.html perhaps? | deng wrote: | Yes, I really hope that JMAP succeeds and applaud Fastmail | for taking this on. The problem of course is that there's a | huge drag in getting new protocols like these established. | One problem is that Fastmail works with Cyrus, but Dovecot | seems to be much more popular nowadays. Of course, getting a | new protocol into Dovecot is a pretty big undertaking, but I | hope they will eventually find the time to do this. | [deleted] | jsilence wrote: | Really wish GroupDAV would have gained more traction. | privong wrote: | I've been using a similar setup for probably 8+ years now. It | started out with an ownCloud instance on a Raspberry Pi B+ (but | has since evolved to nextCloud and a VPS, which I also use to run | other things). I've been incredibly happy with it. I didn't have | to worry about moving my contacts over when I switch to a new | device (whether that be laptop or phone) - I just have to add the | synchronization to the new device. This, plus calDav (I just | `khal` and `todoman` for CLI calendar and to-do lists) have been | excellent. | 7402 wrote: | I spent a lot of time last year looking for alternatives to | iCloud for local syncing of calendar, notes, and contacts for | macOS iOS. It's real easy to spend a lot of time banging your | head against a wall trying to get things working. | | I learned to be suspicious of any posts that said things like | "This should work!" instead of "Here are step by step | instructions for what I actually did that worked for me under | these conditions on this date." Things that work for Windows | don't necessarily work for Macs. Things that work at one time, | don't necessarily work at another time. | | Sometimes there was just one little detail missing, obvious | afterwards but undocumented and costing an hour or two of messing | around to find. Sometimes I gave up on a promising solution (such | as radicale) because I just couldn't find that one missing step. | That's why complete documentation of someone's experience is so | valuable for someone trying to recreate another person's success. | | Here's what worked for me (on Jan 2019), a setup that used | apache, DAViCal, postfix, dovecot on CentOS 7 in VirtualBox on | macOS 10.14: | | "Replacement of macOS Server: Calendar, Contacts, and Mail" | https://7402.org/blog/2019/replacement-macos-server.html | | It was broken by the end of year due to changes by Apple, | requiring the following fix (as of Dec 2019): | | "New self-signed SSL Certificate for iOS 13" | https://7402.org/blog/2019/new-self-signed-ssl-cert-ios-13.h... | | Good luck. It's satisfying to get one's own server working, but | it might take on-going maintenance. | omio wrote: | I remember years ago getting mysql, php, nginx, dovecot, | postfix and horde to work together to get ActiveSync to my | android. Took a long time and lots of reading but in the end it | felt great. Then a week later a horde update broke it. | | In hindsight it's probably better to spend the money on a | hosted solution. | djsumdog wrote: | I've been running Radicale for years!
