ipchains/ipmasq/List of Ports/Exim
The info. you've kindly provided since my first mail has been most
helpful thanks. I am intending to rebuild by debian box over the
weekend with the bare necessities in terms of packages and modules and
with a 100MB HD rather than 500MB.
Before installing ipmasq I entered 'ipchains -nL' and received what I
expected, i.e. a return listing the 3 chains and not much else. After
installing and starting ipmasq the same command returns a much longer
list with more information. Does this mean that both ipchains and
ipmasq affect a single 'service' underlying them both? I read an
article last night referring to MASQ in ipchains commands, is that what
ipmasq is activating?
Assuming my rebuild goes ok I intend to start planning the rules to give
my FW. Can anyone point me in the direction of a list of which ports do
what? I know 23 is telnet from a magazine article but that's about all.
My reason for asking about exim in my last message was perhaps not as
clear as it might have been. I had 2 reasons for asking; 1) I was
wondering if exim is an appropriate tool for making the logs on my FW
available to a masqed box as emails, and 2) If root generates emails
routinely (excuse my lack of knowledge but I don't know if it does) I
had a thought lurking in my mind that they could pile up and fill what
remains of my 100MB drive. With the file system full I guess the FW box
would protest and in effect I would have done a DoS on myself. If I am
talking rubbish, please tell me, but not all at once! :-)
One last thing, which packages do I need to access my FW using ssh?
TIA
Mike
