Hi
Sorry if this is a newbie question, but I _am_ a complete newbie. I am
drowning in documentations and howto's but none seems to deal with my
problem.
I have 2 web-server (f.ex. 192.168.17.1 & 192.168.17.2) behind a
firewall.
How do I make them accesible from the outside so that requests to
130.226.6.10 goes to 192.168.17.1 and requests to 130.226.6.20 goes to
192.168.17.2 ?
At the moment there is access to one of the servers through a
ipautofw -A -p tcp 80 192.168.17.1:80
which works fine with only 1 server, but i am going to have 2 servers
accesible now.
Where should I look to find a describtion of howto do it?
Or is there somthing completely wrong in what I am doing?
tia
Lars

I have a digiboard pc-imac isdn adapter. I am currently using it under
windows nt, but I wish I could convert to unix. On win/nt server, I have
installed the remote ras, and use my nt box as a dial on demand router.
I would love to convert to linux, but I can't seem to find a driver for my
card for linux. I'm new to linux but have unix exp.
Where can I get info on what isdn hardware is supported in linux, and
where can I get a driver for my card?
I have found some vague references to use of a linux box as a dial on
demand router type machine. Any good pointers to setup info?
Thanks,

i've had the same problem but if you use ssh ( secure shell ) you kan log
in as root ( it's encrypted so it's save ) and do a "shutdown -r 1 &"
if you log out now you'll have a reboot in 1 minut ( and you've shell
access if the /etc/nologin file is still present )
suc6 with it

Subject: ppp server no default route
Date: Wed, 14 Apr 1999 10:38:46 +0100
I'm trying to use a linux box (redhat 5.2, 2.0.36 kernel) with a modem
and a direct conection to the ethernet (eth0) as a ppp server (pppd
version 2.3p5).
I can dial in and manually set up pppd using minicom from my similar
Linux
box at home as suggested in the PPP HOWTO. When I quit minicom without
closing the
connection, I start pppd locally as per the PPP howto.
I am then able to ping the remote ppp server, but no further. route -n
shows that there is no default route. There is only one entry pointing
to the ppp interface.
The HOWTO more or less runs out at this point, saying I should explore
the system initialisation files.
I have tried to start pppd with proxyarp, defaultroute or both (when
logged into the server via minicom)
I am using mgetty on the server:
so ps auxw on the server includes:
/sbin/mgetty -x 5 -s 115200 -n 2 ttyS3
My "/etc/ppp/options" file on the server:
asyncmap 0
netmask 255.255.255.0
proxyarp
lock
crtscts
modem
I have an options.ttyS3 file with local and remote IP addresses (both
are legal addresses for our network) on the server as well.
What next?
Thank you for your kind interest

I need to setup a connection between a private LAN and the Internet and
have been monitoring this news group to see whats up. I need the
ability to browse the web and send/receive e-mail. It looks like there
are two ways (maybe more) to accomplish this. One could use network
address translation and port forwarding via Linux ipchains. One could
also setup a cacheing proxy, Squid comes to mind, and mail server, via
sendmail/fetchmail. What I would like to know is what are the pros and
cons of each approach? Some things that I would consider are:
1. Security
2. Configurability
3. Performance
Thanks for any replys!

Subject: Masquerade on Red Hat 5.2...
Date: Wed, 14 Apr 1999 12:37:02 +0200
Hello!
I have two windows computers, and i would like to connect them to internet
through a "server" with a modem.
I found a book that seemd to explain it all and no linux or unix experience
required!, so i bought it; Linux Network Toolkit by Paul G. Sery.
Included with this book was a cd that contained Linux 5.0, diald and other
utilities and some firewall scripts.
Nothing in this book seems to work! i have followed the instructions
carefully...
I have printed out and read trough every ppp, firewall, masquerade and
networking howto included with linux.
Nothing works... (they do not seem to be redhat specific, differet
commands, sceens and so)
I have searched on the web and found pages about how to setup "small office
networks", "home networks"...
Nothing works...
I got Red Hat 5.2 with a magazine, so i have installed it with printer
support, smb and network managment workstation, options.
I can share files and printer with samba, so the basic network is
functional.
I configured modem port and ppp from the control-panel in X.
I have also installed diald 0.16.5a and diald-config 0.16.5a.
In diald's connect file i have only changed to phone.filter, modem init and
phone nr, and in diald.conf i modyfied the line with pppd-options to have my
"pap name"
If i try to get out on the net from a windows machine, nothing happens...
If i from the command prompt type, for example, telnet host01.algonet.se
the modem dials up and nothing more happens.
Now i press ctrl-c to get back the command prompt.
If i type ifconfig, i can see that ppp0 has my server IP and have been
assigned a "p-t-p" IP from the ISP.
This has been my starting point for various ipfwadm configurations.
Have i missed something obvious?
Is there other simpler options than masquerade?
Routing? Proxxy? Other?
Hope someone can help, or point me in the right direction...

A similar problem I ran into: I had ipppd setup to autodial whenever a PC
on the LAN wants to go on the i-net. When ipppd made the connection to my
ISP, the default route disappeared. to solve this, i put 'route add default
ippp0' into the ip-up file.

Subject: pppd eating up memory after Kernel upgrade
Date: 14 Apr 1999 07:32:11 GMT
I have upgraded the Kernel on my RH5.2 from 2.0.36 to 2.2.5 and now when
I'm bringing up the pppd to connct to my ISP it start eating up memory and
it seem to use lot's of I/O (the disk is running crazy) and at that point I
have no option but to shut it down or less it will exshoust the system
completely.
I have tried recompiling the pppd (2.3.7 with the NT chap patch) as advised
on the newsgroups to no avail. It runs fine with the good old 2.0.36 but it
wont run with the latest kernel. Any idea what's going on?
Thanks,
Avishay.

I believe he probably has not configured XF86config.

First of all, make an emergency bootdisk for future use. Also, save your
old kernel, and configure lilo to give you the option of booting the old
kernel, as well as any new kernels you have built. Whenever you rebuild the
kernel, rerun lilo as well.
/lib/modules/preferred is a symbolic link to the current modules directory:
ln -s /lib/modules/`uname -v` /lib/modules/preferred
This should done automatically by the init scripts, but you can do it
manually too.
Remember that when you install new compiled modules fort he same version
kernel, you overwrite the old modules in the same directory. When
recompiling the current kernel, it might be a good idea to save the old
/lib/modules/2.0.34 directory as 2.0.34.old.

What exactly is the problem? Don't make us guess. Do you get any error
messages at boot time? What is the output of "ifconfig"? Can you ping the
localhost, or any other machines on your network? Do you have a DNS server?

I�m trying to print from a LINUX box ( SuSE 6.0 installed ) to a Postscript
Printer attached to a Novell Server.
When I�m trying to print a file with lpr , i get an Error - Message
" /usr/bin/nprint: Server Unknown when initializing connection " or
" No Server found in ncp_open ".
The local Printerqueue - Entry in /etc/printcap looks like :

In /etc/apsfilterrc.<Printername> there�s an entry :

The commands from the ncpfs - Package ( nprint, slist, pqlist ) executed

Command-Line (Shell-Prompt) with nprint or the Skript /usr/bin/novell_print (
used by Suse�s Yast to print to an Netware-Printer ) works too. Printing from
lpr with a skript and an edited printcap-Entry as described in the
PRINTING-HOWTO (Chapter11.3) fails as mentioned above.
Please Help me, I�m getting mad about this !!
