IPChains management
« on: July 27, 2002, 10:29:18 PM »
Hi all. I am an experienced Linux user, using ipchains/iptables. My problem is that I am introducing the e-smith server to some of the classes that I teach. These are mostly newbies and would struggle greatly with manual IPCHAINS configuration etc. Is there some kind of blade or easy management tool that I missed in the server-manager?

What are others doing for the chain management?

Thanks! -Aaron

I recommend using:

Mason:

or

Fbuilder Plus
http://www.icewalkers.com/softlib/app/app_01535.html

Of couse there's something to be said about knowing the console commands and a firm understanding of ipchians outside of a WYSIWYG configurator :)

Hope this helped,
Nathan

IPChains management is automatic. If a service is enabled, then the relevant ports are opened, if not, then they are closed (packets are dropped). All outbound connections are permitted, and masqueraded, which is what most sites want. The only inbound connections permitted are those to services which are enabled for public access.

I hope this information helps.

Charlie, thanks for the response. Unfortunately, totally permissive outbound access from the NAT'ed network is not desirable or secure for all of my situations.

I only want outbound traffic that I deem necessary. Again, yes *I* can do these commands in custom scripts and from the command line. I'm just looking for a web-based or menu based system for my students to use, as they are new to Linux and firewalling and IPChains can be quite cryptic and intimidating to them.

Thanks again, I do love this product for it's ease of use for newbies and school districts.

I'm sure a lot of people would appreciate any add-on to manage outbound connections that you or somebody else can put together. Note that any non-SME specific GUI is likely to be incompatible with the in-built automatic IPChains management. See documentation on this site for how to put an add-on RPM together, and the existing code and templates for ideas on how to have policy based management of ipchains rules.
