Many questions (mostly Network)
1) I have a rather strange setup, and I'm confused on how to implement it.
It looks something like this:
|-----------|
~~~| Gateway | |---[A Machine]
|-----------| |
| |---[A Machine]
|-----------| |
| Fileserv |--------|---[A Machine]
|-----------| |
|
|---[A Machine]
The gateway is given to me by my ISP, and it has a 10baseT connection that
I can hook to one machine. So, the plan is that I'm going to hook it to my
fileserver, and use it as a gateway to the gateway. This way I can use IP
masquerading to allow all of the machiens (with varying OSs) to access the
net.
The machines are all hooked in with the Fileserver using Thin BNC.
The Fileserver is running Linux.
My idea is to have two network cards in Fileserv, one using Thin BNC and
the other using 10baseT. I've noticed that the driver for NE-2000 compatible
cards only looks for cards that have io addresses that I mention.
So my questions are:
* Can I have two ne-2000 compatible cards in the same system?
* assuming the gateway can pump data extremely fast, will I be
losing a ton of permformance by going from 10baseT to thin BNC?
In other words, should I switch my whole system to 10BaseT instead?
(Downloads are VIA satellite... That can be fast.)
* Are there any serious flaws in this plan I'm not seeing?
------------------------------------------------------------------------------
2) I'm running SAMBA on my fileserver (same setup as above). On it, I have
a public directory (both in SAMBA terms and UNIX). However, when someone
attempts to write a file, sometimes it doesn't allow it. Can someone tell
me what has to be done to make a share completely public, so that I can
step through and see where my permissions are bad? Generally, my solution
is to do a "chmod a+rw --recursive" on the directory occsaionally. It
sometimes fixes it.
------------------------------------------------------------------------------
3) Ok, now let's say one of the "A Machine"s is a Linux box that uses PPP to
hook into a secure site (behind a firewall). Let's say (oh, for example)
that everything behind the firewall is 15.19.*.*, and the machine is
assigned an address for PPP that is in th 15.19 domain. What this machine
would want to do is communicate with the PPP line for everything behind the
firewall, and communicate with the fileserver/gateway for everything else--
I assume requiring it to look like a diffrent IP number for each (remember,
the Server/Gateway will be using masquerading). So the question is, how
can I do this and ensure that people on other machines in the network can't
get to the 15.19 domain? Assume that I'm the only one that can log onto the
Linux System I just described... (whew!)
-------------------------------------------------------------------------------
4) I can't for the life of me figure out what the startup files are defined as
or where they are defined (say, .login and .startup.x11 from my old dec
days)
-------------------------------------------------------------------------------
Well, that should do it for now. Thanks for reading this far, and even more
thanks for any answers I get.
