Note: You are currently viewing documentation for Moodle 2.3. Up-to-date documentation for the latest stable version is available here: tracksessionip.
- "It restricts a single session from changing IP, and this is mostly a debugging tool for a strange problem that we think is a PHP bug. It does not stop a single user from having more than one session."
- Martin Langhoff in http://moodle.org/mod/forum/discuss.php?d=47271#217274
- "suppose you logged in using a dial up connection. If you get disconnected and then reconnect, tracksessionip will not let you open pages even if you had your browser open."
- Vikram Solia in http://moodle.org/mod/forum/discuss.php?d=32879#157645
- to turn it on, go to config.php and uncomment:
- $CFG->tracksessionip= True;
// If this setting is set to true, then Moodle will track the IP of the // current user to make sure it hasn't changed during a session. This // will prevent the possibility of sessions being hijacked via XSS, but it // may break things for users coming using proxies that change all the time, // like AOL.
- set dbsessions to "YES" so that sessions are stored in the db
- non-recommended alternative method is to allow domain users write access to the sessions directory (see note at bottom of NTLM_authentication)
