3. TODO Tue Jan 9 13:14:15 EST 2001

• How to test each service section added! (including maybe strace: (mkdir /tmp/strace; mv .../in.ftpd .../in.ftpd.binary, create a two line shell script named in.ftpd with: #!/bin/sh and 'strace -o /tmp/strace/ftpd.out .../in.ftpd.binary' --- I've described strace wrappers and reading strace output in past LG articles; search for some hints))
• More on security of all the services we install (clear text password, DoS by overflowing partition in mail and ftp, http access configs etc), including maybe the very basic ipchains setup (ipchains as safer alternative to tcp wrappers)
• Add info on POP3 and ftp tunneling via ssh (just for fun) or refer to other HOWTOs
• Add troubleshooting subsections to various sections
• Add SSL-enabled Apache install and basic configuration
• Add news server setup - who needs it?
• User accounting setup (acc, acua)
• Description of mail-only users (playing with proxyarp and restricting their access only to the local machine)

3.3 Standard disclaimer

No liability for the contents of this document can be accepted. Use the concepts, examples and other content at your own risk. Additionally, this is an early version, with many possibilities for inaccuracies and errors.

One of many possible setups will be described. In the Linux world, there is usually a number of ways in which to accomplish things.

As far as I know, only programs that under certain terms may be used or evaluated for personal purposes will be described. Most of the programs will be available complete with source under GNU-like terms.

3.4 Support

This is ridiculous, right? Who may ask for support after seeing such a comprehensive doc ;-) ?

Anyhow, if you are curious about some particular aspect of this setup or some of my writing is unclear, just drop me an email and I might answer it (at least, be assured that I will read it).

Now, if you require a phone, hand-holding style support or my work on your system, I might be able to provide it on certain terms (if I have time and your case seems interesting enough ;-) )
