  1. Novell Netware File Recovery and Forensics

  2. What is Netware? • Novell Netware is a network operating system that works on LDAP principles to offer users a robust platform for hosting files printers and other network related services.

  3. History of Netware • Early design in 1983 • Designed to host files to DOS workstations • First OS to use Network Drive Mapping to local workstations • Propriety Designer of the IPX network interface • Originally manufactured by the SuperSet Corporation bought by Novell in 1983 to support a Network OS for the hardware Novell was making at the time.

  4. Netware Facts

  5. Client / Server Interface • With the introduction of Netware 5 Novell Offers its users and administrators a never before seen level of off server management. Meaning that the majority of all work can be done without directly accessing the server through Console1 or Novell’s imanager software

  6. Who uses Netware?

  7. Who Likes Netware? Tony Does

  8. Packet Encryption – How off Server administration works for Forensics • With Netware’s heavy inclusion of RSA standard encryption all transmission from the server to the client (including web clients) is encrypted insuring secure communication and data continuity

  9. File Recovery Programs to Use: - NWFiler (Novell File Utility) - Kroll Ontrack for Netware

  10. Why not Disk Editor • Norton Disk Editor was designed for FAT Partitions, without further testing there's no evidence to support what disk editor will do to a NFS

  11. Filer • On Console or via Network

  12. Salvaging Files To Recover Files use the Salvage Deleted Files Option

  13. To Recover Files from Directories that exist in the File system To Recover Deleted Directories

  14. Enter a Extension or leave as wildcard Navigate to the Folder, Only deleted files and directories will appear in the file browser

  15. MAC Information Confirmation

  16. Recovered file is shown in the original directory

  17. Filer Methodology • Filer was originally intended to be a file browser for Netware administrators • Filer can be used to recover files that have not been purged from the system (files are only purged when a administrator purges it using the “purge” option from the filer menu

  18. When Files have been Purged • Must Be installed on Server – NLM Netware Loadable module • Only accessed by the Server Console or RconsoleJ (Netware remote console with imanager) • Use NetFile Option • Kroll On track File Recovery for Netware

  19. Selecting a Volume File Tree

  20. Supported Recovery Destinations

  21. First Response • Novell Console 1 • Novell Netware Client • Novell NWADMIN • Novell Imanager Tools to use:

  22. Items to Record • Time • IP / IPX Configuration • Users Connected to the Server • Server Running Processes • MAC Times • Console Commands • Log Files

  23. Time – Console • To record the time from the system console simply execute the command “time”

  24. Internet Protocol and IPX Configuration - Console • From the server console execute the command “ipconfig”

  25. Internet Protocol and IPX Configuration – Remote • Open Console 1 • Right Click on Server Object • Under the general – Identification Tab the IP and IPX address are listed

  26. Users connected to the server – Client variant • Novell Send Message Dialog To access the send message dialog left click on the N icon in the windows taskbar, expand the NetWare utilities and click the send message to users menu option 

  27. Users Connected to the Server – imanager variant • Launch imanager • Click the connections menu item

  28. Server Running Processes - Console   To establish processes or programs running on the Netware server, first the user should login to the GUI environment on the server, the open the “remote console program” which simply provides a GUI version of the console, additionally it provides a more organized view for the various console functions. To cycle through the running processes click the screens menu option, this will illustrate the running programs, also if the examiner wishes to view the parameters in which the programs are running simply click on the option under the screens command 

  29. Server Running Processes - imanager • Launch imanager • Choose the “screens” command from the menu • This will display all applications running on the server

  30. MAC Times • Map Volumes to local drives • Use DOS command to view mac times

  31. Console Commands To view recent commands that have been accessed on the server, the GUI Console LOG file will be used, to access the file click on the Utilities and “console log” item from the main menu The accompanying window will show all commands executed on the server

  32. Log Files • Log’s are stored in the system volume under the following path • SYS: JAVA/NWGFX • Must be logged in as admin to access this directory

  33. The Lab: Setup • Groups of 2 or 3 • Two computers connected to a switch • One server, one investigative workstation • Static Assigned IP addresses • Server: 172.16.0.6, Workstation: 172.16.0.7 (255.255.0.0)

  34. Computer 1 : Server • Open the VMWARE image of the server • Run the VMWARE image of the server

  35. Computer 2: Investigative Machine

  36. Accounts Tree CSI1 Context: Admin Server: Theserver Username: admin Password: tcpip
