Where to look for errors

+ +
The LEAP Platform is set of complementary packages and server recipes to automate the maintenance of LEAP services in a hardened Debian environment.
+
+
+ + +

General

+ +
    +
  • Please increase verbosity when debugging / filing issues in our issue tracker. You can do this with adding i.e. -v 5 after the leap cmd, i.e. leap -v 2 deploy.
    • +
  • We use the example.org domain for documentation purposes here, please replace it with the you domain.
    • +
+ + +

Firewall

+ +

Every node in your provider has its own restrictive firewall, but you might have a network firewall in place as well that is not managed by LEAP platform. To see what ports and addresses must be open, run this command:

+ +
workstation$ leap compile firewall
+
+ +

If any of those are blocked, then your provider will not work.

+ +

Webapp

+ +

Places to look for errors

+ +
    +
  • /var/log/apache2/error.log
    • +
  • /srv/leap/webapp/log/production.log
    • +
  • /var/log/syslog (watch out for stunnel issues)
    • +
  • /var/log/leap/*
    • +
+ + +

Is haproxy ok ?

+ +
curl -s -X  GET "http://127.0.0.1:4096"
+
+ +

Is couchdb accessible through stunnel ?

+ +
    +

  • Depending on how many couch nodes you have, increase the port for every test +(see /etc/haproxy/haproxy.cfg for the server/port mapping):

    + +

    curl -s -X GET “http://127.0.0.1:4000” + curl -s -X GET “http://127.0.0.1:4001” + …

    • +
+ + +

Check couchdb acl as admin

+ +
mkdir /etc/couchdb
+cat /srv/leap/webapp/config/couchdb.yml.admin  # see username and password
+echo "machine 127.0.0.1 login admin password <PASSWORD>" > /etc/couchdb/couchdb-admin.netrc
+chmod 600 /etc/couchdb/couchdb-admin.netrc
+
+curl -s --netrc-file /etc/couchdb/couchdb-admin.netrc -X GET "http://127.0.0.1:4096"
+curl -s --netrc-file /etc/couchdb/couchdb-admin.netrc -X GET "http://127.0.0.1:4096/_all_dbs"
+
+ +

Check couchdb acl as unpriviledged user

+ +
cat /srv/leap/webapp/config/couchdb.yml  # see username and password
+echo "machine 127.0.0.1 login webapp password <PASSWORD>" > /etc/couchdb/couchdb-webapp.netrc
+chmod 600 /etc/couchdb/couchdb-webapp.netrc
+
+curl -s --netrc-file /etc/couchdb/couchdb-webapp.netrc -X GET "http://127.0.0.1:4096"
+curl -s --netrc-file /etc/couchdb/couchdb-webapp.netrc -X GET "http://127.0.0.1:4096/_all_dbs"
+
+ +

    • +
+ + +

Databases

+ +
    +
  • Following output shows all neccessary DBs that should be present. Note that the user-0123456.... DBs are the data stores for a particular user.
    • +
+ + +
+    curl -s --netrc-file /etc/couchdb/couchdb.netrc -X GET 'http://127.0.0.1:5984/_all_dbs'
+    ["customers","identities","sessions","shared","tickets","tokens","user-0","user-9d34680b01074c75c2ec58c7321f540c","user-9d34680b01074c75c2ec58c7325fb7ff","users"]

Is couchdb cluster backend accessible through stunnel ?

+ +
    +
  • Find out how many connections are set up for the couchdb cluster backend:
    • +
+ + +
+    grep "accept = 127.0.0.1" /etc/stunnel/*
+
+ + +
    +
  • Now connect to all of those local endpoints to see if they up. All these tests should return “localhost [127.0.0.1] 4000 (?) open”
    • +
+ + +
+    nc -v 127.0.0.1 4000
+    nc -v 127.0.0.1 4001
