personally i would opt and get a router. i have a cable modem and i use the router to recieve an ip from the ISP then the router issues my lan IP's via DHCP. its really easy and works really well.
currently i have my xp/xbox/freebsd machine online even tho my isp issued me 1 ip.
the chain works like this.
ISP -> cable modem -> router -> my computers.
if you want to go the free way you shoudl look at ipmaskerading and ipchains for linux. this will give you firewalling and software routing for your machines.
as for the last questions. check out ssh for secure remote connections.

I recently installed Caldera 2.4 (successfully:p ), but I cannot seem to get my cable modem up and running! My ISP is AT&T and I'm using @home. I've tried using DHCP and that didn't work either. I briefly read the cable modem HOWTO, but the lsmod didn't list my network card (3COM). What do I do now? (4 Replies)

ctrlaltdel
CTRLALTDEL(8) System Administration CTRLALTDEL(8)
NAME
ctrlaltdel - set the function of the Ctrl-Alt-Del combination
SYNOPSIS
ctrlaltdel hard|soft
DESCRIPTION
Based on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft reset,
which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1). If this option is used, the init(8)
program must support this feature. Since there are now several init(8) programs in the Linux community, please consult the documentation
for the version that you are currently using.
ctrlaltdel is usually used in the /etc/rc.local file.
OPTIONS
-V, --version
Output version information and exit.
-h, --help
Display help and exit.
FILES
/etc/rc.local
SEE ALSO
init(8)
AUTHOR
Peter Orbaek <poe@daimi.aau.dk>
AVAILABILITY
The ctrlaltdel command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils
/util-linux/>.
