You should DEFINATELY use private addresses for any machine that does not
have an IP address from your ISP. However, the machine that connects to
the internet will use an IP from your ISP for that connection (ppp or
whatever). In this case you would use IP Masquerade to hide your private
LAN from the outside world. The internal machines can still communicate
with the internet, but machines on the internet cannot connect to your
internal network unless you let them. See the HOWTO on IP Masquerade for
more info.

For Perl there is a Net::FTP module available, but is is probably not on
your system (CPAN @ www.perl.com). The libnet modules include:
Net::FTP RFC959 File Transfer Protocol
Net::SMTP RFC821 Simple Mail Transfer Protocol
Net::Time RFC867 Daytime Protocol
Net::Time RFC868 Time Protocol
Net::NNTP RFC977 Network News Transfer Protocol
Net::POP3 RFC1939 Post Office Protocol 3
Net::SNPP RFC1861 Simple Network Pager Protocol
There is a separate Net::Telnet module also.

I am not familiar with the technique you are using, but I have used 'rlpr'
to print on my Linux box from a telnet session to Solaris which uses a
totally different printing system than Linux does. Although, I did have
to run rplr's proxy in Linux, because I did not know how to set up lpr to
accept remote printing. For the Solaris end, I simply compiled rlpr on
Solaris and set up .rlprrc with my Linux hostname and printer (I have
static IP).

Have you tried simply: telnet 172.66.1.1
(substitute the actual address of your Linux box)
or from the Linux machine iteself try: telnet localhost
Check /etc/hosts.allow and /etc/hosts/deny and see 'man 5 hosts_access'
For other machines on the LAN to recognize your machine by name you will
either need DNS or put IP and names in /etc/hosts or \windows\hosts of
machines involved. Also put IP name entries for any non-DNS names that
will connect to Linux in its /etc/hosts. Linux likes to do a reverse
lookup on anyone that connects to it.

you will have to enable IP forwarding/gatewaying in the kernel (parameter
CONFIG_IP_FORWARD). Then simply configure your intefaces via ifconfig, and add
static routes for the two networks, pointing to the relevant interfaces (route
add -net ..., see 'man route'). With this configuration, users should be able to
communicate across the two networks.

I finally gave up on this and switched back to the
3com etherlink III 509TP. To get this to work
ran 3com config utity in dos mode on both
machines. Them in Linux I setup the
Kernal config as
io=
irq=7
addl args=
Note this will only work with the io and add args left
blank. Now wasn't that intuitively obvious? The one
thing that clued me into the extra field problem was
an error message like don't understand io= and
mem=.
Hope this helps someone.
I havn't been able to get these cards working with
an NT server and win95 client. I downloaded the

Hello,
In the global section of smb.conf is line that starts with 'hosts allow=',
if you remark this line with semicolon, samba will allow all clients on the
interface it was started.
Also look at man smb.conf
Good luck!

I've networked two Win95 PCs using the SOHOware Network ISA cards and
hub (10M). So far, I can't get the RedHat 6.0 installation routine to
recognize this network (I want to install Linux to a network drive).
I haven't quite given up yet but it sure don't look good. There's some
discussion of rebuilding the kernel with a revised version of tulip.c;
but if I can't install Linux, I can't rebuild the kernel for the
installer.
If I get it working, I'll let you know.
