Ohh, never tried the preemptive auth checkbox… Then its working. I have tried on this for ours. ;-(
Thank you!
Local sync between phone and laptop
-
Well, problems solved!
Linux Mint 19 which I’m using distributes Radicale 1.1.6, when the current version is 3.0 !.. So I completely removed the packages and installed through python as instructed on the Radicale website.
For future reference:
- you have to create a config file with this setting https://radicale.org/3.0.html#tutorials/basic-configuration/addresses for the server to be accessible
- not knowing how to add a calendar from Evolution, I added one with the web interface. It shows a complex URL for the calendar, like http://localhost:5232/loginname/long_hash/ . This has to be put as-is in Evolution to add this new calendar; I didn’t manage to fetch calendars from Evolution. However in DAVx5 it was enough to enter the base URL http://laptop_IP:5232/, loginname and PW for it to find the calendars created in Radicale.
I hope this will help other newbies!

Bottom line: the color is OK in DAVx5 and Etar. In Evolution and Simple Calendar it’s not (it may have been corrected in Simple Calendar Pro).
-
@LL Great!
Most other clients don’t have a resource detection like DAVx5 has. In these clients you must point them directly to the respective URLs that represent the calendar/addressbook.

I’m facing another problem. Let me recall the setup: Radicale server on a Linux laptop, DAVx5 on an Android 8.1 phone. I want to interconnect them in two possible ways: at home they are both connected to a Wifi router; when roaming the laptop connects to the phone used as access point (AP).
The difficulty is the subnets have different IPs in the two situations. At home both devices are 192.168.1.x ; in the phone AP the latop is 192.168.43.y . The Wifi router subnet number cannot be changed; for the phone AP subnet I don’t know (the phone is not rooted).
I thought “whatever, I’ll use named URLs”. I point DAVx5 to http://coulomb:5232/ (coulomb is the hostname of the laptop). In the Wifi router subnet it works. But when the laptop is connected to the phone AP it doesn’t. The phone DNS seems OK because if I run
host coulomb 192.168.43.1this gives the correct IP (obtained from 192.168.43.1#53). Here is the log of DAVx5 for the failed sync (I trimmed the collection which I believe to be irrelevant):--- BEGIN DEBUG INFO --- SYNCHRONIZATION INFO Account: Account {name=-, type=bitfire.at.davdroid} Authority: com.android.calendar EXCEPTION java.net.UnknownHostException: Unable to resolve host "coulomb": No address associated with hostname at java.net.Inet6AddressImpl.lookupHostByName(Inet6AddressImpl.java:111) at java.net.Inet6AddressImpl.lookupAllHostAddr(Inet6AddressImpl.java:90) at java.net.InetAddress.getAllByName(InetAddress.java:787) at okhttp3.Dns$Companion$DnsSystem.lookup(Dns.kt:1) at okhttp3.internal.connection.ExchangeFinder.findHealthyConnection(ExchangeFinder.kt:67) at okhttp3.internal.connection.ConnectInterceptor.intercept(ConnectInterceptor.kt:20) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.kt:14) at okhttp3.internal.cache.CacheInterceptor.intercept(CacheInterceptor.kt:213) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.kt:14) at okhttp3.internal.http.BridgeInterceptor.intercept(BridgeInterceptor.kt:38) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.kt:14) at okhttp3.internal.http.RetryAndFollowUpInterceptor.intercept(RetryAndFollowUpInterceptor.kt:35) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.kt:14) at okhttp3.logging.HttpLoggingInterceptor.intercept(HttpLoggingInterceptor.kt:52) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.kt:14) at okhttp3.brotli.BrotliInterceptor.intercept(BrotliInterceptor.kt:31) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.kt:14) at okhttp3.internal.connection.RealCall.getResponseWithInterceptorChain$okhttp(RealCall.kt:25) at okhttp3.internal.connection.RealCall.execute(RealCall.kt:13) at at.bitfire.dav4jvm.DavResource$propfind$2.invoke(DavResource.kt:19) at at.bitfire.dav4jvm.DavResource$propfind$2.invoke(DavResource.kt:1) at at.bitfire.dav4jvm.DavResource.followRedirects$build(DavResource.kt:1) at at.bitfire.dav4jvm.DavResource.propfind(DavResource.kt:10) at at.bitfire.davdroid.syncadapter.CalendarSyncManager$queryCapabilities$1.invoke(CalendarSyncManager.kt:3) at at.bitfire.davdroid.syncadapter.CalendarSyncManager$queryCapabilities$1.invoke(CalendarSyncManager.kt:1) at at.bitfire.davdroid.syncadapter.SyncManager.remoteExceptionContext(SyncManager.kt:1) at at.bitfire.davdroid.syncadapter.SyncManager.remoteExceptionContext(SyncManager.kt:8) at at.bitfire.davdroid.syncadapter.CalendarSyncManager.queryCapabilities(CalendarSyncManager.kt:1) at at.bitfire.davdroid.syncadapter.SyncManager$performSync$1.invoke(SyncManager.kt:6) at at.bitfire.davdroid.syncadapter.SyncManager$performSync$1.invoke(SyncManager.kt:1) at at.bitfire.davdroid.syncadapter.SyncManager.unwrapExceptions(SyncManager.kt:1) at at.bitfire.davdroid.syncadapter.SyncManager.performSync(SyncManager.kt:5) at at.bitfire.davdroid.syncadapter.CalendarsSyncAdapterService$CalendarsSyncAdapter.sync(CalendarsSyncAdapterService.kt:14) at at.bitfire.davdroid.syncadapter.SyncAdapterService$SyncAdapter.onPerformSync(SyncAdapterService.kt:13) at android.content.AbstractThreadedSyncAdapter$SyncThread.run(AbstractThreadedSyncAdapter.java:321) REMOTE RESOURCE http://coulomb:5232/any/87e6ddbb-7bf0-1619-b12a-ce6b01e80315/ SOFTWARE INFORMATION ┌────────────────────────────────┬──────────────────────────┬────────────┬─────────────────────────────────────┬───────┐ │ Package │ Version │ Code │ Installer │ Notes │ ├────────────────────────────────┼──────────────────────────┼────────────┼─────────────────────────────────────┼───────┤ │ at.bitfire.davdroid │ 3.3.4.1-ose │ 303040100 │ com.google.android.packageinstaller │ │ │ org.dmfs.tasks │ 1.2.4 │ 78500 │ com.google.android.packageinstaller │ │ │ com.android.providers.contacts │ 8.1.0 │ 27 │ — │ │ │ com.android.providers.calendar │ 8.1.0 │ 27 │ — │ │ │ com.android.contacts │ 1.7.10 │ 10710 │ — │ │ │ com.google.android.calendar │ 5.8.34-198051655-release │ 2015821617 │ — │ │ │ ws.xsoh.etar │ 1.0.23 │ 25 │ com.google.android.packageinstaller │ │ │ com.mobisystems.fileman │ 6.12.37871 │ 37871 │ com.android.vending │ │ └────────────────────────────────┴──────────────────────────┴────────────┴─────────────────────────────────────┴───────┘ SYSTEM INFORMATION Android version: 8.1.0 (ECHO_FEELING_V01_20180821) Device: ECHO FEELING (FEELING) CONNECTVITY ☒ [ Transports: CELLULAR Capabilities: INTERNET NOT_RESTRICTED TRUSTED NOT_VPN VALIDATED FOREGROUND LinkUpBandwidth>=51200Kbps LinkDnBandwidth>=102400Kbps Specifier: <1>] Data saver: disabled CONFIGURATION Power saving disabled: no System-wide synchronization: automatically Notifications: -

@LL said in Local sync between phone and laptop:
The phone DNS seems OK because if I run
host coulomb 192.168.43.1this gives the correct IPDid you run the host command on the phone (where DAVx5 runs)?
DAVx5 uses okhttp, which uses the system DNS to resolve the host names. So nothing special…
-
@rfc2822 no I ran it on the laptop. Is it possible to run such commands on a non rooted phone? With adb maybe?
-
@LL adb shell, and nslookup/host should be there
-
adb shell → I have neither nslookup nor host…
Butping coulombanswers “unknown host”, so it looks like the phone cannot use its own DNS
? -
@LL Sounds reasonable, because DAVx5 uses the same DNS. So DAVx5 should work when ping works and in the other direction.
Maybe coulomb.domain?
-
I finally solved this last problem. I posted it on SE: https://android.stackexchange.com/questions/230983/the-phone-as-hotspot-doesnt-use-its-own-dns/231206#231206
It turns out this is expected behavior: the phone as a DNS client doesn’t use the DNS server it runs.However I installed Virtual Hosts which allows to define custom hosts entries without rooting the phone. The app is really easy to switch on/off, so I’ll be able to use it only when I sync DAVx5 (which I do manually only) through the phone access point.
Happy syncing!
