NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.
ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.
Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.
Register users on your TWiki site; change/reset/install passwords; remove user accounts
Some of the features below may be disabled, depending on your TWiki
Authentication and Access Control
You don't have to have user home pages in TWiki for Authentication to
work - see TWikiUserAuthentication
Change, Reset and Install Passwords
Note that the below features are only relevant when you use an internal password manager where TWiki can set and reset passwords.
- ChangePassword is for users who can remember their password and want to change it
- ResetPassword is for users who cannot remember their password; a system generated password is e-mailed to them
- BulkResetPassword if for administrators who want to reset many passwords at once
- ChangeEmailAddress changes the hidden email address stored in the password file
Changing User Account Names
To change the user's WikiName
- Rename the user's TWiki homepage in the Users web, such as from
- Fix backlinks in the Users web only
- Make sure the group topics are updated (if any.)
- Edit the Users.TWikiUsers topic and move the user's entry so that the list is in proper alphabetical order.
- Recreate the old topic with a pointer to the new topic, so that links in other webs work properly. Example content:
%M% Jane Smith is now known as JaneMiller
If external authentication is used and you want to change the login name:
- The login name needs to be changed in the authentication server (e.g. Active Directory)
- In TWiki's Users.TWikiUsers topic, fix the mapping from login name to WikiName:
* JaneSmith - jsmith - 13 Sep 2006
* JaneMiller - jmiller - 13 Sep 2006
Removing User Accounts
To remove a user account (FredQuimby, who logs in as "fred"):
- If you are using a
.htpasswd file, edit the
.htpasswd file to delete the line starting
- Warning: Do not use the Apache
htpasswd program with
.htpasswd files generated by TWiki!
htpasswd wipes out email addresses that TWiki plants in the info fields of this file.
- Remove the
FredQuimby - fred line from the Users.TWikiUsers topic
FredQuimby from all groups and from all the
ALLOWWEB/ALLOWTOPIC... declarations, if any.
Note: If you fail to do this you risk creating a security hole, as the next user to register with the wikiname FredQuimby will inherit the old FredQuimby's permissions.
- [optional] Delete their user topic Users.FredQuimby (including attachments, if any.)
Consider leaving the user topic file in place so their past signatures and revision author entries don't end up looking like AnUncreatedTopic
. If you want to make it clear the user is no longer around, replace the topic content with a note to that effect. The existance of the UserName topic should also prevent that user name from being re-used, sealing the potential security hole regarding inherited permissions..
