maemo.org - Talk - Nokia N900 A-GPS Not Working Anymore

I know that (and openssl returns also error when not pointed to /etc/certs/common-ca).
But why on earth does cmcli return an error even when pointed explicitly to common-ca???
That made me thinking of hard-coded certs in GPS blob.

And why supl.nokia.com returns result for N900 when using proxy?

caveat: afaik supl.nokia.com is geo-ip, and just _some_ (most?) of the boxen are broken. You however may pick a good one at random

Code:

jr@saturn:~> host supl.nokia.com

supl.nokia.com is an alias for nokia.supl.svc.ovi.com.

nokia.supl.svc.ovi.com is an alias for nokia.supl.geo.geodns.fi.

nokia.supl.geo.geodns.fi is an alias for de.nokia.supl.geodns.fi.

de.nokia.supl.geodns.fi has address 213.157.72.147

Re: Nokia N900 A-GPS Not Working Anymore

May I add:
# host supl.nokia.com
supl.nokia.com is an alias for nokia.supl.svc.ovi.com.
nokia.supl.svc.ovi.com is an alias for nokia.supl.geo.geodns.fi.
nokia.supl.geo.geodns.fi is an alias for dk.nokia.supl.geodns.fi.
dk.nokia.supl.geodns.fi has address 83.150.75.211

I was thinking of this too (okay, more have it running on my dyndns linux box). Main issue is: supl-proxy stops after each request/session.
Someone would have to extend the code to a forked mode or sth ...

How much traffic (kb/mb) in an exchange?

See my logfiles. About 3kB for sirf, nokia and vodafone (with result) . 40-50kB for google and sonyericsson (no usable result). Of course double each at proxy server.

For the ones still interested:
Installation of supl-* from tajuma.com is fairly easy linux standard. The software package has pretty good documentation i.e. a README which is definitely worth the name.
I didn't try building it for N900, I wouldn't know where to start for that.
I recommend installing it on a linux machine in your local network with

Code:

./configure --precompiled-asn1 --prefix=/usr/ && make && sudo make install

Generate the required certificates with included supl-cert prog. Instead of a fqdn as the first param just give the ipaddress of your linux machine. Then scp the file ca-cert.pem to your N900 and install it as a common certification authority with (as root)

Code:

cmcli -c common-ca -a /path/to/ca-cert.pem

Then do the preceeding steps from my previous post, setting location server in N900 to your linux box ip address.

Thats interesting!
So we need to find a working nokia.supl box (maybe from nokiabot in india?) and put that ip into /etc/hosts on our N900 ...

Edit: That probably doesn't solve the cert issues :(
Edit2: There seem to be just 4 ip addresses around for supl.nokia.com:
211.151.53.216
213.157.72.147
213.157.79.103
83.150.75.211

Re: Nokia N900 A-GPS Not Working Anymore

Whilst there is yet no solution, this thread has expanded knowledge!

If supl.nokia is geo variable yet actually works for some (does it? Nokiabot did not report back on a reboot scenario with ACWP) then certs may not be a critical factor.

That may well be so.
This is from my machine at work:

Code:

$ host supl.nokia.com

supl.nokia.com is an alias for nokia.supl.svc.ovi.com.

nokia.supl.svc.ovi.com is an alias for nokia.supl.geo.geodns.fi.

nokia.supl.geo.geodns.fi is an alias for us.nokia.supl.geodns.fi.

us.nokia.supl.geodns.fi has address 213.157.72.147

$

...and this is from home:

Code:

$ host supl.nokia.com

supl.nokia.com is an alias for nokia.supl.svc.ovi.com.

nokia.supl.svc.ovi.com is an alias for nokia.supl.geo.geodns.fi.

nokia.supl.geo.geodns.fi is an alias for uk.nokia.supl.geodns.fi.

uk.nokia.supl.geodns.fi has address 213.157.72.147

$

Note the us versus uk but the IP addresses are the same.

FWIW, none of the 5 URLs from post #101 nor the nieldk's IP address (83 etc) worked for me. I am in the UK, tested with ACWP on a home WiFi network. My last lock was one reboot and about a week ago and about 100 km away so caching is out of the equasion.

Hmm, this is getting more weird:

Code:

Re: Nokia N900 A-GPS Not Working Anymore

hmm, could you please explain to me what I see in post above, and what I conclude from that. I'm probably not into this cert stuff enough to even interprete the cmcli commands and their diagnostic output, the less I see how we're going to fix this stuff now.
