HI,
I think your problem is on the client side. The subnet mask should probably be
255.255.255.0
yours ended in 128. If your server is not setting the environment
(read:network) for less nodes you should default to .0 (subnetmask)
Hope I was of help,
Seth

Er - I would think that you'd need to specify a netmask for a net route
(e.g., route add -net 192.168.3.0 -netmask 255.255.255.0 gw
192.168.0.150).

Subject: Re: Need help: POP/SMTP not working (RH5.2)
Date: Tue, 31 Aug 1999 22:27:27 -0700
Hi,
Loading IMAP fixed the POP3 side. (Thanks, Stuart)
I am still dead sending mail.
More details on my configuration: I'm running ipfw on a RH5.2 box to
connect my inside net to the outside world. The goal is that every
computer in the inside (192.168.1.0/24) gets EVERY service from the
firewall box. This box has two cards, one is 192.168.1.254, and the
other has a static IP to my ISP. I'm running local DNS services also
(bind 8.1), one server for the inside, one on the wall, and one that
forwards/caches off my ISP's server. (OK, I'm not running an NNTP
server; can't afford the bandwidth)
The mail get rejected when the client (Netscape on an internal box)
tries to send it to 192.168.1.254. The dreaded "We do not relay"
message. I know it's important to filter relays; some guy out there
constantly tries to bounce mail off of me. I can see messages in the
firewall log saying that I'm denying his connection.
There are a couple of files in /etc/mail; ip_allow, name_allow, and
relay_allow. I have no idea what the structure of these files should
be, they were all empty at install.
So.... How do I get my local server to accept messages, and ONLY ones
from me?
If I'm in a shell on the wall, I can send mail, so I think the sendmail
part is working.
Gary.

Subject: Can't install 3c509 on RH5.2
Date: Tue, 31 Aug 1999 21:19:18 -0700
Greetings.
I'm installing RH5.2 at home, and for some reason it's not recognizing
my 3c509 network card. Oddly enough, though, it *used* the card during
setup to do the install via FTP.
Here's what I know:
- Card is installed correctly, no hardware conflicts, and its LED lights
up.
- upon /etc/rc.d/init.d/network start, returns "Delaying start eth0".
- ifconfig eth0 returns "eth0: unknown interface".
- insmod 3c509.o returns several (ca. 10) unresolvable symbol errors.
Any advice?
Thanks-
Andy Perrin

ok, i've dug around the web for about four hours now, so here i am...
i have a compaq presario 4112 that i am using for a firewall. i'd like
to be able to boot it w/o a keyboard. the bios does not have the nice
'Halt on errors' option like modern bios' do. does anyone in the NG
know how to fool the box into thinking that it has a keyboard plugged
in? surely there is a way to 'short' the ps/2 connector (i've tried
w/o success, though).

Hi,
First, don't use root...
I had the same problem in the same environment when I tried to compile
nfs server as a module. When I compiled it right into the kernel, the
problem went away and now I can use it.

You may want to try out kppp and using the Prompt or PWPrompt command to enter
the secure ID number that you need to enter it in (and do it in less than 30

Subject: Setting up Masquerading under RH6.0
Date: Wed, 01 Sep 1999 02:19:51 -0400
I have a need to setup a dial-out server using PPP. I have the PPP
scripts all installed and tested. The dail out server can surf the web
and all that stuff. Now I want to be able to masquerade the internal
network we have here with the Internet. Below is the firewall script I
wrote down. There are a few requirements:
1.) Firewall doesn't restrict ANY internel traffic. Clients should be
able to use samba, ftp, etc.
2.) Firewall forwards packets to destinations not located on the
internel network. Reverse is true, return packets are sent to the
request machine.
Simple rules.
Problems are:
1.) Can't resolve domain names from dial out server.
2.) Can't ping from clients (i.e. another computer tries to ping to
www.yahoo.com through dial out server).
3.) Can't ping from clients to the IP assigned by my ISP.

I used Linux boxes as DNS/Firewalls a couple years ago(I
left, they're still there). I think it was a RedHat 5.2
distro I used. It really won't matter which distribution
you use - Linux is Linux. Red Hat just packages extraneous
stuff in their distribution that you probably won't need
anyway
