1) have a look at TCP wrappers (man tcpd), or see
(the new, shinier) freshmeat appindex record at:
http://news.freshmeat.net/appindex/1998/12/08/913153273.html
2) at a much lower level, there's ipchains, or the older

Hi,
I�m using Slackware, Apache 1.3.3 and SSLAEY 0.9.0, and it was
configured correct, but when I tried to setup my verisign key, in the doc in
verign I dind�t find the right commando in SSLAEY. Does anybody know how can
I configure it?
link at verisign that explain step by step to configure their key :
http://www.verisign.com/guide/apache/apache.html
and in this part below the command that i couldn�t find!
=====
Run getca
Specify both the name of the server that owns the ID and the name of the
temporary certificate file. For example:
# getca hostname < /tmp/cert.tmp
Note: In some versions of SSLEAY, you should use the command getversign
instead of getca.
Your Secure Server ID should now be saved as the file
SSLTOP/certs/hostname.cert
Thanks

Subject: Linux firewall doesn't forward anything - HELP!!
Date: Thu, 7 Jan 1999 10:26:40 +0100
The following roughly represents the configuration I have set up. The
Internet connection is leased line.
Internet
--------
|
|
a.b.c.d
Cisco 2503 router
-----------------
e.f.g.145
|
|
eth1 10BaseT e.f.g.146
Linux Firewall
--------------
eth0 100BaseT 192.168.2.60
|
|
Hub
---------------
| | | | | | | |
| | |
| | |
192.168.2.1 | 192.168.2.3
|
Hub
---------------
| | | | | | | |
| | |
| 192.168.2.50
|
Hub
---------------
| | | | | | | |
| | |
The above more or less resembles our network setup. I am able to ping
e.f.g.146 and 192.168.2.60 (the internal and external addresses
for the two ethernet cards on the firewall) from another Linux machine
on the inside at 192.168.2.50. I can ping the Cisco (e.f.g.145)
from the firewall. What I can't do is ping the Cisco from the internal
Linux machine. Also, if I try to ping an unknown address 54.32.105.18,
for instance, no attempt is made to use the route defined as default,
and I get "Unknown network" as the result.
The routing table on the firewall looks like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
e.f.g.144 0.0.0.0 255.255.255.240 U 0 0 5 eth1
0.0.0.0 e.f.g.145 255.255.255.240 UG 0 0 0 eth1
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 6 eth0
127.0.0.1 0.0.0.0 255.0.0.0 U 0 0 5 lo
As can be seen from the Use column, the default route has not been used,
even
though I have tried to ping addresses which would require that route.
If anyone has any idea, or can pass this to someone who might be able to
shed
some light on what is going wrong, I would be very grateful. I have spent
about 10 days on this now and it seems that I am getting nowhere any longer.
Additional information:
The system is RedHat 5.2, using the kernel 2.0.36. I have recompiled the
kernel with the options as defined in the IP Masquerading mini-HOW-TO. IP
Forwarding is on. ipfwadm has been installed and configured to accept on -F
from
the local network (192.168.2.0).

Date: Thu, 7 Jan 1999 06:46:04 -0500
Ok, I am a moron when it comes to Linux. Just starting to really use it
and I need help from all of you Guru's.
I have set up a second machine that is running RedHat 5.2. My first machine
is a WinSlows 98 machine. I have Samba running with out too much trouble
(share access, not user access).
My Linux box is a P-166 with 98Mgs of memory (lots of it) and (1) 1.2 Gig
IDE (NT Server), 85Mg IDE(Root) and (4) 1.5 Gig SCSI-2 drives. /usr,
/user/local, /home, /arcs.
What I want to do is move my 56k modem to my Linux box and have it be my
dialup connection. I am using Wingate on my 98 machine now, so my son and
daughter can use their machines on the net, but I have to start the dial up
process on my 98 machine.
How can I get Linux to do this automatically?
I know this is a BIG question..........
In case you are interested, I run NT Server on this box too. Dual Boot.
To play and figure out how to get it to be a DNS, DHCP and RAS box.
But mainly I use it and my kids machines as a Rendering Farm for a piece of
RayTrace Animation software called LIGHTWAVE. Using Screamer Net I can have
4 CPU's processing the animations instead of just 1 CPU. Really cool and
FASSSST....

We use SMC Ultra cards at work and I use them at home on several systems. There is
a DOS utility called EZSTART that allows you to configure and test the cards. The
program is easy to use without documentation. After the card is setup it can be
put in any AT slot.
For some reason the linux probe for this card gets screwed up on PCI motherboards.
I setup the card to run on IRQ 10 at I/O Address 0x280 so I have lilo start linux
with the following argument.
ether=10,0x280,eth0
On one motherboard I had to set the PnP BIOS setting for IRQ 10 to legacy.

AFAIK this should work.

Subject: How do you configure second network card: Redhat 5.2?
Date: Thu, 07 Jan 1999 12:15:30 +0000
Reply-To: [EMAIL PROTECTED]
Hi,
I have recently built a new box using Redhat 5.2. This has two network
cards
installed. I went through the remote installation procedure (its very
good!)
and got the box working with one of the cards. However I wish to now
configure the second card.
With Slackware its easy, I just edited the /etc/rc.d/rc.inet1 file (I
think
that is what it was called) and added another ifconfig and route
statements.
How do I do this with Redhat? It seems the files in /etc/rc.d are to be
configured
by some user tool rather than editing the files themselves?
I came across a tool called linuxconf, but that seemed to be no help, so
there
must be something else!
TIA

One thing that I tend to do is have the syslog go to virtual console 6, then
all I have to do is control-alt-F6 to see the current messages. If you have
RedHat 5.2 and you save this message in /tmp/syslog.patch, and then do as root:
# patch < /tmp/syslog.patch
# shutdown -r now
it should set it up for you. Note, I run the development kernels with matroxfb
and configure my text windows to be 1280x1024 (for the work machine) or
1152x864 (for the home machine), so that I can see more lines in the log file.
