In fact ipmasquerading is a subset of NAT but it doesn't do what you
want. You will need IP Filter�3.2.9:
http://cheops.anu.edu.au/~avalon/ip-filter.html
or anything else that suits your needs at:
http://www.uq.net.au/~zzdmacka/the-nat-page/nat_unix.html
There you will find everything. Sorry I can't help on the technical
aspect. Ipmasquerating does everything I want for the moment so I
didn't get a chance to explore.

I second the ucd-snmp suggestion.
I've been using it for over 2 yrs now.
http://ucd-snmp.ucdavis.edu is where you get the pkg.
to see some stuff that I've done with it, go to my page:

can be brought into the actual Kernel? Is there a certain version

any of those should work.
what's important is the video card, the network card and sound card.
any disk, cpu, ram will work.
most network cards work.
most older video cards work (matrox is one of the better ones).

this makes sort of no sense, they should be ext2fs - i think.
sharing involves some fileattributes- and for that you would need to
write .
( this would explain why you sees the dummy-files, right?)

Hello,
I just got my RedHat 6.0 CD and some new net cards. I installed the net
cards and then installed RedHat 6 but when it came to the network config
window and I had it probe my net card the entire thing froze, I tried not
probing and it still froze, so I had to install it with out network support.
I just tried to use linuxconf and it froze again. I'm dual booting on both
computers (It's just a home network) and windows is working fine using the
same cards. The cards are both Intel EitherExpress PRO/10. I'm about ready
to delete RedHat 6 and see if 5.2 will work. thank you for any help.

Do you have a route to each of the segments?
route add -net 172.20.201.0 dev ethX
You might want to post the results of 'ifconfig' and 'netstat -nr'

One method I could suggest you and you might
play with it is to install vmware because it will
install you a "virtual ethernet". You can even
simulate Samba connection in your standalone

Subject: Sendmail Addressing Variables
Crossposted-To: comp.mail.sendmail

Does anyone know how to get Sendmail (on RedHat 5.2) to route
messages with address variables to a specific mailbox?
Example: [EMAIL PROTECTED] Or,
[EMAIL PROTECTED]
As you can see, the user name is always prefixed with "fax", but
the rest is variable (may be different every time). I need
message addresses prefixed with "fax" but followed with a
variable number to be sent to the same mailbox every time. Is
there a way to do this?
For any help rendered, many thanks in advance.

on the other hand, a pci (or other) device which could itself do ppp
would be a cool thing. once you write a frame, the modem wouldn't
wait and time-out looking for more data. you could move the packets
back and forth using dma. uarts with their constant flood of nickel
and dime interrupts make a lousy interface. make an modem with
ethernet card interface!
unfortunately, modem vendors are avoiding a smart card and building
idiot cards with as little as possible on them. oh well.

I think he did so (kernel option "IP: syn cookies", #defines

I am trying to use a RH 5.2 box as a firewall with three ethernet
cards... There are three subnets, one connected to the big bad
internet (call it eth0, 123.123.123.23, its connected to
123.123.123.22 at the isp), one connected to a public local net with
external IP address (say eth1 123.123.124.1) and one connected to a
private local net (eth2 172.20.201.1). The firewall can ping to hosts
on each of the three subnets, and vice versa. However, I cannot get
hosts on the private net to ping hosts on the public local net
(ie. 172.20.201.10 -> 123.123.124.5), nor vice versa (couldn't test
the big bad internet because the ISP hasn't connected the wire in yet
:-( ).
In /etc/sysconfig/network on the firewall machine.
FORWARD_IPV4=true
GATEWAY=123.123.123.22
GATEWAYDEV=eth0
Clearly, I am missing something, but I can't figure out what. Perhaps
it's because I have three cards installed on the machine and that's a
touch beyond the standard RH install scripts (I guess I should have
stuck with slakware...)
