chown'ing the files and directories under /opt/modrana worked for me as well.

Absolutely fantastic!!! Thank you!

Installation is a breeze, dl from 1st post, installed without a glitch! no dependence problems.
Run right out of box, no crashes.
Interface is very intuitive, if nothing else, the userface should be a model for a lot of other apps.

Thanks for the good app, early congratulation that this is going to be a hit!

Yes, chmod for /opt/modrana is a good solution! Now it remembers the options! And it doesn't have apparent problems with logging!

I'll try to do a field test soon.

To MartinK:

get file
postinst
in debian directory
and add line like
chmod -R 0777 /opt/modrana
or something similar

It might resolve many issues.

I would rather the ownership of directories issue be fixed instead of grant full rwx to all users.

Good job finding the permission issues, thanks!

I for now added

Code:

chmod -R a+rw /opt/modrana

to the postinst script. I know this is not ideal, but I dont have a real N900 (well, yet

) so I cant just look what the default username/uid is

So, I would like to ask:

Whats the default username/uid ?
Is it always the same ?
Can it possibly be changed by the user ?
Is there some other way how to consistently set folder ownership ?

Then I can replace it by something like this:

Code:

chown -R default_user /opt/modrana
chmod -R o-rw /opt/modrana
chmod -R ug+rw /opt/modrana

I replaced the package with a new one with modified postinst, name/URL are the same.

Yes.

No, all default N900 services and apps run as user:users

How about integrating turn-by-turn navigation, ala navit? This would beat the crap out of any commercial nav...

Thanks a lot! I'll change the postinst script right away.

EDIT: done, package reuploaded

Well, routing results returned by Google already contain driving directions, for example:

Code:

Turn <b>left</b> at <b>London Rd/<wbr/>A40</b> <div class="">Continue to follow A40</div>

At junction <b>8</b>, exit toward <b>Thame/<wbr/>Milton Common</b>

For now, the direction messages are only signalized by yellow points when the route is drawn and their number is shown in "route info".

So, basically I just have to show these messages near corresponding trackpoints and we have a nice turn-by-turn navigation.

With espeak, it should be possible to read them aloud too.

Oh, wow, so that should be easy to integrate, if they're in this format, having espeak just read them out loud at approapriate points in time, and we're there...

This is great...

Ideally everything should be

- owned by root
- not writeable by any user other than root (except for config files/user generated files etc)

For modRana 0.12 (the version I've installed) the following should tighten up and set the correct permissions:

make everything owned by root
chown -R root:root /opt/modrana/

allow user to create new files in /opt/modrana/data/
chmod o+w /opt/modrana/data/

allow user to create new files in /opt/modrana/tracklogs/
chmod o+w /opt/modrana/tracklogs/

repeat the chmod for any other directories in which user needs to create files
