Guide to TechDocs for administrators and content creators

This is the UNSW CSE TechDocs MediaWiki server. It's:

• A MediaWiki server delivering technical information on CSE's computer systems to CSE students and other users,
• A Linux server providing a collaborative content creation platform for authorised users,
• A SAMBA server for file sharing,
• An SSH server, and
• A documentation automation platform for creating, managing and populating MediaWiki pages.

---

• MediaWiki's formatting help page
• MediaWiki's top-level help page
• MediaWiki API documentation start point

---

• It's techdocs.cseunsw.tech
• Access limited to UNSW subnetworks
• All wiki pages are public
• Authorised editors
• SAMBA and file sharing
• SSH access to the TechDocs server
• Install techdocs server
• Shared content creation account ("techdocs")
• Administration notes
  • MediaWiki users and groups
  • MediaWiki user authentication
  • Local host logins and user accounts
  • SAMBA
    • User names and passwords
    • Local host user accounts
  • SSH keys and SSH access

pandoc is installed. Amongst other things, it can be used to convert from HTML (e.g., old, handwitten web pages) to MediaWiki wikitext by doing something like this:

$ pandoc -f html -t mediawiki -o newpage.wiki oldpage.html

The result of the conversion can then be pasted in to a TechDocs wiki page.

---

The maintenance directory in the untarred MediaWiki directory (i.e., /usr/local/mediawiki) contains a large number of PHP scripts which can be used for maintenance and administration. See the file list below from v1.38.1 and ponder the README and then maybe look at nukePage or getText.php).

Usually, if you run the PHP scripts in the maintenence directory without parameters you'll get a usage message. E.g.:

# php undelete.php
Argument <pagename> required!

Undelete a page

Usage: php undelete.php blah blah blah... ("blah blah blah..." added by the editor)

Actions for site administrators

Note: There is no central account database (like LDAP or the UDB). Access for the wiki, SMB and SSH are all handled separately and manually.

Granting access

Creating a user account on the wiki with create and edit privileges

1. As an administrator…
2. Left-hand panel
3. Special pages
4. Login / create account
5. Create account
6. Enter details (no privileges need to be assigned as a user account automatically has the required privileges). Similar user name as CSE account is recommended
7. Create account
8. Done

Create local login account

Required for SSH or SMB access. Not required for wiki-only access

Note: All SMB user accounts automatically have access to the "techdocs" share.

1. As root on the host…
2. If only SMB access required (no SSH):
   • useradd -s /usr/sbin/nologin <username> (an /etc/passwd entry for the user must exist)
3. If SMB and SSH access required:
   • useradd -s /bin/bash -m -p x <username>
   • Set up user's SSH key in the account's .ssh/authorized_keys file
4. smbpasswd -a <username> (supply desired password)
