Thank you @smbd for reporting this.

Do you have by the chance already solved?

We have actually still not reproduced the error so i’m asking you if you could provide some additional information.

The fact that the Onion Service is not working and that in the log you have logs of connections refused make me think that for sure the Tor process is not starting or it is not correctly opening its ports for configuration.

Could you please verify an provide information about the following:

is the Tor process running?
could you please post the output of “/var/globaleaks/torhs# ls -al”
could you please verify if in dmesg you have some error in relation to apparmor?

smbd · June 7, 2017, 8:05am

Not solved as of now.

smbd · June 8, 2017, 2:48pm

@evilaliv3 any suggestions?

evilaliv3 · June 8, 2017, 4:06pm

still not @smbd

we have never tried to update a platform from a distro version to an other, but always ported the data directory.

try to understand why tor is not started and why it is not able to access the hostname/key files in /var/torhs

the startup of tor is quite completely independent from globaleaks and the only thing that we configure for that is an apparmor script: https://github.com/globaleaks/GlobaLeaks/blob/master/debian/globaleaks.postinst#L45

The problem is with owner and permissions of /var/globaleaks/torhs:

root@x2://var/globaleaks# ls -l /var/globaleaks/
total 16
drwx------ 2 globaleaks globaleaks 4096 Jun  8 18:00 db
drwx------ 7 globaleaks globaleaks 4096 Apr 11  2016 files
drwx------ 2 globaleaks globaleaks 4096 May 16 08:31 log
drwx------ 2 debian-tor debian-tor 4096 Jun  4 22:45 torhs

If I change torhs owner to globaleaks after a restart, it goes back to debian-tor

fpietrosanti · June 15, 2017, 12:41pm

This problem seems to have happened multiple time in past:

Does gl-fix-permissions script fix the problem as a workaround?

evilaliv3 · June 15, 2017, 1:32pm

@fpietrosanti that command is executed at any startup of globaleaks so i do not think that would fix the issue.

i’m so looking forward for the integration of the patch for avoiding to use the filesystem when dealing with Tor.

evilaliv3 · June 15, 2017, 1:42pm

@smbd now tha i rethink to the fact that you told to have updated the distribution, maybe you have resetted the /etc/tor/torrc?

does it still contain this lines?

VirtualAddrNetwork 10.23.47.0/10
AutomapHostsOnResolve 1
TransPort 9040
TransListenAddress 127.0.0.1
DNSPort 5353

HiddenServicePort 80 127.0.0.1:8082

smbd · June 15, 2017, 1:48pm

@evilaliv3 no, during the upgrade we opted to keep old /etc/tor/torrc. Tor wouldn’t start immediately after the upgrade. Later we deleted the old /etc/tor/torrc and pasted only GL config below into the new file. It still did not work.

# BEGIN GlobaLeaks Configuration - DO NOT EDIT!

# END GlobaLeaks Configuration - DO NOT EDIT!

nskelsey · June 15, 2017, 1:54pm

Hey @smbd

I think you can just copy /var/globaleaks/torhs directory (with perms for debian-tor) outside of /var/globaleaks and change the following line in /etc/tor/torrc to the new path:

HiddenServiceDir /path/to/torhs

This is a proposed work around. . . but because GL only needs the config once (on system init) it seems ridiculous to me that it is blocking normal startup+restarts.

nskelsey · June 20, 2017, 4:04pm

Hi @smbd we believe we have identified the issue on 16.04 and have a fix.

systemd has added its own sandboxing that silently controls some permissions on the system. You can run the following commands which come from globaleaks.posinst and it should resolve the issue.

mkdir -p /etc/systemd/system/tor\@default.service.d
# Add Systemd rules for allowing Tor to access to directory /var/globaleaks/torhs/
cat <<EOF >> /etc/systemd/system/tor\@default.service.d/directory.conf
[Service]
ReadWriteDirectories=-/var/globaleaks/torhs/
EOF

systemctl daemon-reload

I ran into this on a similar 16.04 instance today and it resolved the issue. Let us know if it works for you.

smbd · June 20, 2017, 9:51pm

@nskelsey Yes, this fixed it. Thanks a lot.

Now another issue. Our Letsencrypt certs expired. We renewed them, changed and verified all symlinks.

However this is what we see in the logs now:

nskelsey · June 21, 2017, 10:31am

@smbd the certificate and keys for SSL are loaded in the database when using the HTTPS built into GL. You need to access the platform from the administration interface using the Tor browser, disable HTTPS, replace the expired lets encrypt certificate with the new one and re-enable HTTPS.

Right now, we are finished up a feature to automate the renewal using Let’s Encrypt. It will go live in v2.68.0 before the end of June.

smbd · June 21, 2017, 11:08am

@smbd although both tor and globaleaks are up now (confirmed by ps) and firewall is disabled sudo ufw disable, our onion site is still inaccessible via Tor browser

nskelsey · June 21, 2017, 1:26pm

This is unfortunate, sorry it is such a challenge to get the service up. I have 3 questions:

Is GL responding on its local port?

curl localhost:8082

Is tor listening on 9050?

netstat -tulpen

Is the tor hidden service configured with the expected onion address?

# check tor log and syslog
less /var/log/tor/log /var/log/syslog
# check config
less /etc/tor/torrc
# check onion address
cat /var/globaleaks/torhs/hostname

Okay, its a bug within GL that got shipped in v2.67.5 we just released a fix in v.2.67.9. Update the globaleaks package and you should be able to connect.

There was an erroneous redirect preventing the interface from loading.

@nskelsey Now we cannot update SSL because we cannot log in as admin to Onion.

The message says Error! The resource is available only via Tor browser.

The problem is that WE ARE using Tor browser when trying to log in.
