I've been playing around with the idea for some time. Ok, let me give a little background, and then my intentions. I'm a systems engineer with degrees in programming, networking, and analysis so feel free to get technical peoples. :) I've been researching more and more into security and have been experimenting with fundamental network operations. My goal is to set up my own personal WAN in my lab (in my house) and monitor packet payloads of rudimentary network operations such as dns cache updates, ARP, ns lookups, dn translations, maybe even as far as active directory replication, remote LDAP mods, DHCP, etc... I've got a collection of 9 computers dating back no more than 7 years in my lab that have been set up as DDNS web servers in the past, but i don't need them anymore. I'd like to set up a series of dedicated DNS servers, routers, separate dubnets, a client machine, a couple web servers, and what not on a private WAN all objects running some kind of net monitor to document what goes on, how and when. I'm not sure how i'm going to model these after the real internet. What OS's should i use for each object? I have access to any kind of OEM installer including Server2003 Enterprise, Redhat, Ubuntu, XP-Pro. Non of this model will be connected to the real net, ideally i'd like to try and break my system to try and prevent it at the office. Any advice? Any books, labs or documentation you could recommend? How would you do it? What experiments would you conduct? moreResolved Question: iptables script not working sometimes?
ok, so I have a firewall script that I want someone to look at for me, tell me if I have some rules in it that are wrong.. but I have this script, everything is working, everything is working great its just when I restart and I put in the command line, iptables-save, and when I restart the rules are there but no computers are getting packets.. I have DHCP, its working great, but its the firewall script I think I am having a problem with, Can someone look at it and tell me if its bad? #!/bin/sh # # Generated iptables firewall script for the Linux 2.4 kernel # Script generated by Easy Firewall Generator for IPTables 1.15 # copyright 2002 Timothy Scott Morizot # # Redhat chkconfig comments - firewall applied early, # removed late # chkconfig: 2345 08 92 # description: This script applies or removes iptables firewall rules # # This generator is primarily designed for RedHat installations, # although it should be adaptable for others. # # It can be executed with the typical start and stop arguments. # If used with stop, it will stop after flushing the firewall. # The save and restore arguments will save or restore the rules # from the /etc/sysconfig/iptables file. The save and restore # arguments are included to preserve compatibility with # Redhat's or Fedora's init.d script if you prefer to use it. # Redhat/Fedora installation instructions # # 1. Have the system link the iptables init.d startup script into run states # 2, 3, and 5. # chkconfig --level 235 iptables on # # 2. Save this script and execute it to load the ruleset from this file. # You may need to run the dos2unix command on it to remove carraige returns. # # 3. To have it applied at startup, copy this script to # /etc/init.d/iptables. It accepts stop, start, save, and restore # arguments. (You may wish to save the existing one first.) # Alternatively, if you issue the 'service iptables save' command # the init.d script should save the rules and reload them at runtime. # # 4. For non-Redhat systems (or Redhat systems if you have a problem), you # may want to append the command to execute this script to rc.local. # rc.local is typically located in /etc and /etc/rc.d and is usually # the last thing executed on startup.
