Date: Sun, 24 Jan 1999 00:38:18 GMT
Greetings -
I'm looking to set up a firewall/NAT linux box for my network, and need
to pick a distribution.
This is going to be a production box, and must be up at all times. I
don't want something that I'll have to putz around with for weeks to get
running and keep running.
Any recommendation for a distribution? I'm guessing it'll be either
Redhat or Slackware, my question is which which is more tried and tested
- and more suitable for this application?
Thanks,
Iven Connary

/sbin/ifup <interface>

No. RH uses system-V-ish init scripts, scripts to start or stop
services are located in the directory /etc/rc.d/init.d . Symbolic
links are used to control the runlevels at which each script is
invoked; use the chkconfig program to manage these links.
dhcpcd may be called by /sbin/ifup , this is separately configurable
for each interface. Look at the /etc/sysconfig/network-scripts/ifcfg-*
files, a line like:
BOOTPROTO=dhcp
will cause dhcpcd to be used to configure an interface. I assume that
the network configurator can be used to arrange this, but I prefer to
just edit the ifcfg-* files by hand.

Hello,
I am stuck behind a firewall that doesn't allow me to access my computer
from off campus. However, I have access to a computer on campus runnin
Linux that could do the forwarding for me. Does anyone know of something
similar to ipautofw or ipportfw that would allow me to simply forward all
packets that come in _on only one of the interfaces_ to another computer? I
don't think ipfwadm can do this, at least not that I have been able to
setup. Any hints or references (other than the howtos and man pages which I
have read) would be apprecitated.

What does "started a connection" mean? Do you have ppp running? How do
you know?
Can you ping the server's IP number (not name). If yes, you have a ppp
connection. They your porblem is probably that your win machine does not
have a DNS name server to get its addresses from. Does Win have a hosts
file? Make sure that the name of your server is in the hosts file.

Hello!
I'm using a (SuSE) Linux-system with Kernel 2.0.33. Now I need a new
Kernel - version 2.0.36.
I followed all instructions to configure it. "make dep" and "make clean"
worked fine, but "make zImage" cancels with the following message:
gcc -D__KERNEL__ -I/usr/src/linux-2.0.36.SuSE/include -V2.7.2.3 -Wall -Wstri

init/main.c
gcc: installation problem, cannot exec `cc1': No such file or directory
cpp: output pipe has been closed
make: *** [init/main.o] Error 1
Maybe I should mention, that I used a source-code patch for an olicom
tokenring-card (olicom-2.0.36). But this source-code patch could be applied
without problems.
How can I run the "make zImage" sucessfully?
Thank you!

I believe Windows 98 by default is using encrypted passwords. If your samba is
not set up
for encryption this will not work. You have two choices if this is the case:
- set samba up so it uses encryption(see the howto).
- set windows 98 so it used plain text passwords. This requires changing
the registry. I'm
sorry, I do not know the exact option but I found the information a
couple of months ago by
searching through the newsgroups.

It hadn't occurred to me that I might not need to authenticate to
access the mail server...That's definitely food for thought. I may
have to try that... I don't know if I'd be able to ping the server;
the address is just a name, not in IP form. Still, if I didn't need to
authenticate, it would solve problem #1! Of course, if I do need to
then I'm back to square one. I read somewhere that Samba is pretty
well documented. I'll have to take a look.

That's what I was wondering! I don't know what the "normal" protocol
is between Outlook and Exchange. The way Outlook is configured on my
laptop certainly isn't for POP/SMTP. That would be the "Internet Mail"
service. It's specifically set for Exchange server. But what does that

Subject: Re: PPP doesn't work when eth0 is active
Date: Fri, 22 Jan 1999 09:31:30 -0500
Sounds to me like you have a default route pointing to eth0. Type route -n
and see what comes up. You're default route will be 0.0.0.0 and you should
see a device associated with it. Also, you'll probably see the flags -UG
(indicating UP and Gateway).
If this is indeed the case, you'll need to get rid of the default gateway.
Initially, try "route del default" to delete it. Then, try to establish
your ppp connection. Once you think the ppp connection is
established...type "ifconfig" to verify that the interface has been created.
Then, do another route -n to see what routes are active.
Eventually, you'll need to edit (I think it's /etc/network) and remove the
default route and default gateway device.
If you have RH 5.2, you can make the correction using linuxconf. Remember
to reboot.
In my RH 5.2 setup (which is similar to yours), I have two routes set up and
NO default route. This results in some warnings at startup but don't seem
to affect my system. I should also point out that my machine is configured
with IP Mascarade and that I have another script that runs to set up the
routes here as well. But, even if I don't run the script, the other steps
solved the problem you describe.

A hub would probably be very useful.

Yes. Linux (like UNIX) has a program called "cron" which enables you to
schedule things to run at regular intervals. For example, if you set
things up so that typing 'pppd' established the connection, and were
running Exim as your mail transfer agent and Fetchmail to retrieve mail
from the ISP, you might have a crontab file that looked like this:
0 * * * * root pppd
2 * * * * root runq
2 * * * * root fetchmail
5 * * * * root killall pppd
This would dial in each hour, wait a couple minutes, send and receive
mail, wait a couple more minutes, and kill the connection.
You might also write a script that called these various commands, then
create a single crontab entry for it.
You might also decide that you didn't really need the server to call
between midnight and 7 AM, or at all on weekends, and change it to look
something like this:
0 7-23 * * 1-5 root pppd
2 7-23 * * 1-5 root runq
2 7-23 * * 1-5 root fetchmail
5 7-23 * * 1-5 root killall pppd
>Can I set the server to dial out only when someone wants to surf the web?
I think so. The PPP daemon has a "demand" mode, in which case it only
establishes the connection when there's traffic. I haven't used this
mode myself.
> How many users can use the dialup at a time?
That depends how fast your modem is, and how fast each user wants to go. :)
If you have a 56k modem, you can have 1 person getting 56k, or 2 getting
an average of 28k each, or 56 getting an average of 1k each, or about 170
getting the rough equivalent of 300 baud each... *grin*

Sounds to me like you have a default route pointing to eth0. Type route -n
and see what comes up. You're default route will be 0.0.0.0 and you should
see a device associated with it. Also, you'll probably see the flags -UG
(indicating UP and Gateway).
If this is indeed the case, you'll need to get rid of the default gateway.
Initially, try "route del default" to delete it. Then, try to establish
your ppp connection. Once you think the ppp connection is
established...type "ifconfig" to verify that the interface has been created.
Then, do another route -n to see what routes are active.
Eventually, you'll need to edit (I think it's /etc/network) and remove the
default route and default gateway device.
If you have RH 5.2, you can make the correction using linuxconf. Remember
to reboot.
In my RH 5.2 setup (which is similar to yours), I have two routes set up and
NO default route. This results in some warnings at startup but don't seem
to affect my system. I should also point out that my machine is configured
with IP Mascarade and that I have another script that runs to set up the
routes here as well. But, even if I don't run the script, the other steps
solved the problem you describe.

Subject: Please help: "Permission Denied" with RH 5.2 and rsh
Date: Sat, 23 Jan 1999 21:38:14 -0500
Greetings!
I've installed Red Hat 5.2 on several machines but cannot get
rsh to work. The master system is setup as an NIS slave, and I
can login and have my home directory mounted, etc. I don't have
NIS running on the slaves (they're on a private 10.x.x.x network
and I don't want to fiddle with NAT at the momemt) but I created
a duplicate of my NIS account on one of the slaves (with the
same UID and GIDs), chown'd the home-directory files and
created the appropriate .rhosts and /etc/hosts.equiv files.
No matter what though, I get "Permission denied" when I try
to rsh from the master to the slave. Is this something to
do with PAM?
Please help - Beowulf is waiting! :-)
Regards,
Ed

Hi Luke!
If you configured Firewall with Linux you can set the <FW_REDIRECT> in the
rc.config-file.
The variable contains a list of tripels which have the following format:
local port, target ip, remote port
I think the fcii daemon (firecracker) does this job. But I think it uses
ipfwadm to do it..
Bye,
Erich
