Re: [tor-talk] Problem with where hidden_services able to be placed/permissions.

I understand.

In Debian, if installed via apt-get, Tor will run under user debian-tor.

If you create the hidden service directory in /home/user/Documents,
this doesn't give the permissions to the user running Tor, which is as
I said 'debian-tor' and not 'user'.

Please follow up below and see comments inline:

OK, this is normal.

Tor cannot generate new hidden service files in
/home/user/Documents/hidden_service because this is owned by 'user'
and Tor is run by 'debian-tor'.

Do this: leave in torrc:
HiddenServiceDir /home/user/Documents/hidden_service

And run these commands:
chown -R debian-tor:debian-tor /home/user/Documents/hidden_service

chown -R debian-tor:debian-tor /home/user/Documents/hidden_service/*

This won't work unless Tor is also started/reloaded (so it'll generate
the hidden service files), and you need to add each time entries in
torrc for each user for this to happen:

HiddenServiceDir /home/user1/Documents/hidden_service/
HiddenServicePort 80 127.0.0.1:80 # or whatever you use

HiddenServiceDir /home/user2/Documents/hidden_service/
HiddenServicePort 80 127.0.0.1:80 # or whatever you use

You also need to change the owner of all hidden_service folders for
each user to debian-tor using the commands above.
