The reason for this is that even +in the latest CSSU, supl.nokia.com no longer works as a location server. The fix +for this is actually relatively quick and easy and will make an initial GPS fix +take seconds rather than minutes. + +$pre + +The exact details of what needs to be done can be found in the last few posts of +[this][tmo-thread] Maemo forum thread. The problem is that supl.nokia.com no +longer resolves to an IP address. However, this doesn't mean that the server +behind supl.nokia.com is no longer running. Surprisingly, it still is. + +The long and short of it is this: + +1. Make sure you have the latest CSSU and a working N900 to begin with; +2. Go [here][certman] and download `libmaemosec-certman0_0.2.10_armel.deb`, + `libmaemosec0_0.2.10_armel.deb`, `maemosec-certman-common-ca_0.2.10_all.deb`, + and `maemosec-certman-tools_0.2.10_armel.deb`; +3. Install the above packages via the command line as root (you'll need gainroot) + by using `dpkg -i` (put all the files in their own directory and use `dpkg -i + *` to save time); +4. Edit `/etc/hosts` and change `supl.nokia.com` to point to `52.200.182.188`; +5. Check it all works by running `cmcli -T common-ca -v supl.nokia.com:7275` and + `cmcli -T location-proxy -v supl.nokia.com:7275`, both should say "Verified + OK."; +6. If this doesn't work, try `stop location-proxy` and then + `start location-proxy` (as root) and go back to step 5. + +GPS fixes should happen very quickly now. If it's the year 2023 and this didn't +work then good luck finding a new fix, hopefully you put the details on your +blog too. Alternatively, feel free to contact me and I might still be using the +N900 and might know how to help. + +[tmo-thread]: https://talk.maemo.org/showthread.php?t=90651 +[certman]: http://maemo.merlin1991.at/cssu/community-devel/pool/free/m/maemo-security-certman |
