Final word

...Guess I just need to get the last word in:

The nice thing about Ubuntu is that so many things work out of the box. One bizarreness that I found is that you may need to add some non-default locations to be scanned for software updates/downloads (eg, getting Codecs that can't be shipped with the OS). But once that's set up, there's very little hassle in downloading or updating software. Everything just works together.

Oh- except for 3D graphics. That was a hassle too. But that was 1.5 years ago, maybe it's better now.

I even did a full upgrade once... just grit my teeth, closed my eyes, and hit the "Upgrade" button. With no backups (I was too lazy). After much disk thrashing and holding of breath, the machine upgraded fine.

Not that I recommend it. But it's nice to see how far Linux has come and, like you, I am discovering that the older I get the less time I have for screwing around with stuff. It needs to just work or I move on. This leaves me room to screw around with those things I'm really interested in. :-)

if.conf

NETSCRIPT-2.2.conf(5)						File Formats Manual					     NETSCRIPT-2.2.conf(5)

NAME

       /etc/netscript/network.conf - interface, firewalling, and QoS configuration file.

       /etc/netscript/if.conf - interface setup shell script file

       /etc/netscript/qos.conf - QoS setup shell script file

       /etc/netscript/ipfilter.conf - IP chains filtering shell script file

       /etc/netscript/srvfilter.conf - server IP filter shell script file

DESCRIPTION

       This manpage is a place holder until something better is written when the netscript itself has stopped changing rapidly.

       Please  see  the README file in the /etc/netscript directory, and READ the configuration files if you need to change them.  Apart from net-
       work.conf, all of them contain sh (1) shell script functions which are there so that various things can be altered  or  hooked  in  at  the
       right place. Network.conf contains the full network setup details, including special interface setup for the likes of ciped/pppd/wanconfig,
       and is fully commented with examples given.

UPGRADE PATH FROM KERNEL 2.2.X
       The firewall/IP filtering stuff in ipfilter.conf is the part that changed radically with the move to iptables and a far better way of  set-
       ting  up  the  IP filtering rules, however the QoS and interface startup/shutdown in if.conf have changed but are backwards compatible with
       the old 2.2.x ipchains version of netscript for the interface address configuration settings.  You will have to set up the filtering  again
       to use iptables by directly using the iptables commands.

       Also,  the  kernel  2.2.x version scripts are set up so that iptables is only run on a 2.4.x kernel, otherwise IP forwarding is disabled if
       beforehand you set IPFWDING_KERNEL to FILTER_ON in network.conf.

       This means that when you upgrade a box to a 2.4.x router kernel, you should then be able to reboot it and log  into  remotely  and  upgrade
       netscript  to  the version that will support 2.4.x.  In this situation, if you have set old IPFWDING_KERNEL setting to FILTER_ON beforehand
       in network.conf, all IP forwarding through the box will also be disabled.  This means that you can safely remotely upgrade a firewall.
