9. 9 Installation Experiences Apache configuration s Posix directory tree created using ZFILE  “/usr/local/apache/…”  conf - Configuration files  logs - Log files  htdocs - HTML documents

10. 10 Installation Experiences Apache configuration (cont.) s Configuration directives  “conf/httpd.conf” – Download to workstation via FTP – Update file – Upload to TPF via FTP – Restart Apache s No “conf/srm.conf” or “conf/access.conf”  “conf/httpd.conf” – ResourceConfig /dev/null – AccessConfig /dev/null

11. 11 Installation Experiences Apache configuration (cont.) s Time and research required s Documentation available  “htdocs/manual” subdirectory  O’Reilly’s Apache: The Definitive Guide

12. 12 Installation Experiences Activating Apache s Starting the server  ZINET START S-APACHE s Stopping the server  ZINET STOP S-APACHE s Stop/start required when  “httpd.conf” modified  Loadset(s) activated (due to Nolisten problem)

13. 13 Apache at Inovant Security plans s Inovant will be developing a custom security module to be linked into Apache DLM  Will interface with revised version of Inovant’s existing SNA/IP remote terminal security package  Will provide security services not part of standard Apache authentication module – Password history, session time-out, logging, audit trail, etc.

14. 14 Apache at Inovant Security plans (cont.) s Web server and its internal files will be protected from outside access using standard Apache directory and file directives s Separate directory structures will be provided outside the web server for application scripts and data s We will be developing utilities to monitor and archive the error_log and access_log files created by Apache in the “log” directory

15. 15 Apache at Inovant Security plans (cont.) s References  O’Reilly’s Writing Apache Modules with Perl and C  Security Tips for Server Configuration – http:// www.apache.org/docs/misc/security_tips.html

16. 16 Apache at Inovant Planned use at Inovant s Web-based data security administration s Existing TPF functional messages s MQ administrative functions s Remote console access

17. 17 Planned use at Inovant Web-based data security administration s Convert existing remote terminal security administration functions to web-based interfaces s Add new security administration functions to support the external Apache security module

18. 18 Planned use at Inovant Existing TPF functional messages s Replace user interfaces of application and middleware functional messages  C++ and Perl CGI  Java applets s Only functions not required below CRAS state s User-friendly graphical interfaces  Not direct one-for-one replacements of green screens  Field-level help  Language support (French, Spanish, etc.) s No “screen scraping”

19. 19 Planned use at Inovant MQ administrative functions  GUI interfaces for all ZMQSC entries  List all defined queues and queue depths  Browse items on queue  Delete an item  Transfer an item  Clear a queue  Put a test message

20. 20 Planned use at Inovant Remote console access s Web-based replacement for 3270 SNA remote “green screen” console access s 3270 emulator no longer required s Utilize existing remote terminal security package s Links to web-based documentation and help for TPF functional messages s Prototype Java applet has been developed to interface with a TCP/IP socket server application

21. 21 TOC Demo Prototype based on existing functional messages Standard web technologies s HTML, forms, CSS s C++ CGI s Java, JavaBeans User-friendly interface s Non-cryptic display s Mouse-over help s Multiple language support No “screen scraping”
