Use ipportfw
You can map a connection from A on a specific port to B on any other port
you specify

Ok I'm a Linux newbie. I have COL 2.2 and want to create a 1.5g partion
for Linux. Partion Magic Caldera Edition isn't flexible enough for me. I
know to use fdisk instead then, but I dodn't know how to use it. When the
fdisk menu came up it just scared me to death because I had no idea what I
was doing. Could anyone walk me through the step of creating a 1.5G
partion. Thank you.

Subject: IP Masqeurading: help needed
Date: Tue, 29 Jun 1999 13:56:01 -0700
I have a small home LAN consisting of two Linux (RedHat 6.0) boxes. One
of the machines is connected to the outside world via a DSL connection
with a permanent IP address and functions as the router for the other
machine. I am using IP Masquerading with ipchains.
Things seem to work quite smoothly (I can ftp, telenet, browse from both
boxes to the oustide). However, I am not able to directly access the
second box from the outside world when I need to FTP or Telnet to it. I
am under the impression that it is impossible to achieve that since the
second box does not have a valid IP, but only has a one for local use.
Since being able to access the 2nd box directly from the outside is
improtant for what I want to accomplish I thought of checking with some
of the gurus out there to see if I have missed something. Could IP
aliasing help for this? Any suggestions?
Thank you

Subject: Swap over NFS
Date: Tue, 29 Jun 1999 23:09:42 +0200
Hi all,
does anybody have hints on how to swap over NFS?
I've a linux client here and a Sun (running Solaris) which provides all
the directories via NFS. All's well exept for swapping! :-(
Any hints on how to export the swapfile from Solaris? Or how to import
(mount) it correctly on the Linux box? Kernel is 2.2.10 ...
At the moemnt, I've the swapfile mounted quite ordinary and loop it, then
I do a mkswap to the loop devce and then issue a swapon to it...
This seems to work, but I get several error messages like:
swapon: Unable to find swap-space signature
ll_rw_block: Trying to read non existent block-device 00:04 (0)
My /etc/fstab looks like this:
server:/fs/rboot/linux-sparc/root / nfs defaults 1 1
server:/fs/rboot/linux-sparc/swap/ /nfsswap nfs defaults,sync 1 1
proc /proc proc defaults 0 0
devpts /dev/pts devpts mode=0622 0 0
server:/fs/rboot/linux-sparc/usr /usr nfs defaults 1 1
And I'm using the following script to set up swapspace:
SWAPFILE="/nfsswap/myclientsswapfile"
echo "Setting up swap over NFS... "
losetup /dev/loop0 $SWAPFILE
mkswap -v1 /dev/loop0
swapon /dev/loop0
mkswap -v1 /dev/loop0
swapon /dev/loop0
echo "done."
I noticed, that I had to create the swapfile TWICE (using mkswap),
otherwise it did only say
/dev/loop0: invalid argument
Can anyone expplain this, PLEASE???
Or can anyone, as said before, give hints on how to swap over NFS?
THANKS!!!!!
Andi

1. Of course this is a (serious) bug. Why on earth would it be
acceptable that a NFS write only works when the client and server
segments comply with certain speeds?!?
2. The server happens to be in our UNIX segment, which (alas) is 10MB;
it is out of my control.
I find it quite amazing that this problem has come up so little and
even people don't seem to care. I know I shouldn't complain about free
software, but still, if such basic networking (NFS) doesn't work well
I'm getting some doubts on Linux. I mean, even NT clients handle this
NFS situation better than Linux.

Basically what I am trying to find out is whether it is possible (for
example) to setup IP forwarding so that when I telnet Box A (the router)
at a particular port of my choice, Box A will forward the connection to
the standard telnet port on Box B. Obviously I have some reading to do,
but at least if I know it can be done I can invest the time to learn
how. (more details in my original post below) -- Thanks!

Get it from the 3Com web/ftp site. May be available alone or else grab the
"Superdisk" for the 3c509.
You want the 3c5x9cfg.exe program. From DOS:

I know you want to see a solution in the daemon but I don't think it's there.
Try defining it CLIENT SIDE! (in windows) MS reinvents everything..
LPR -C xxx ........ (from NT admin guide)
usually sets the class name which is in turn printed on the burst page.
I'm grasping here but try researching this option (in windoze), maybe not
specifying anything in the 'xxx' field turns it off.
Actually I think your dilema is more with TCPIP than Linux. And we
all know how MS pretties up commands when they feel like it.
Hope I've added something positive .. if not ... sorry.

Subject: Trying to use Linux DHCP client with Sygate
Date: Tue, 29 Jun 1999 21:36:24 GMT
I am trying to use Suse Linux DHCP client with Sygate.
I have Sygate 3.0 running on my NT box connected to
the internet through a cable modem. The the IP address
for the local network card this box is 192.168.0.1 as
usual. I also have a HP Ombinook 4100 that dual boots
to Win NT and Suse Linux 6.1. It uses a Xircom Realport
10/100-56K PCMCIA card. In NT the card is setup to
use DHCP. When i hook the laptop into my local hub
connected to the second NIC on the Sygate machine, it
uses Sygate's DHCP service and it all works fine.
In Linux mode I am using /etc/pcmcia/network.opts file
to configure the network options on the laptop. Only
thing I set in that file is the DHCP="y" option and
everything else I left empty as "". After that when
I try to ping the sygate machine with "ping 192.168.0.1"
the request simply times out. But when I brought in
the laptop at work and plugged it into the office network
while keeping the /etc/pcmcia/network.opts config exactly
the same, it seems to work just fine. It gets DNS, IP
address, etc assigned by the NT DHCP server used here
at work without any problem. Can somebody tell me what
could be wrong in my Sygate setup at home? Could it be
an issue of the domain name assigned to the Linux machine
during installtion ?
I did try starting dhclient (dhcp client) by hand and I
got a bunch of messages about inadequate or improper
DHCPOFFER being recieved.
I also tried using fixed IP address = 192.168.0.2, netmask,
= 255.255.255.0, etc. in the network.opts file at home.
Then I am able to ping the Sygate machine and able to reach
outside world using IP addresses of machines. But I am still
not being able to use the Sygate service for DNS for
some reason. Do I have to point to my cable modem provider's
DNS host ? Can't I point to the Sygate machine ? May be
I need to set something properly. I would also appreciate
an answer for this.
But I would really like to use the DHCP feature if I can.
That way I can use the machine both at home and work
without too much hassle.
many thanks for any suggestion

the point being
1) if you don't need templates, go ahead and use C.
2) if you *do* need templates, get a better language than C++.
actually i don't mind the templates in C++. they are rather weak, but
not hard to use and are not terribly confusing
what i do mind is the object orientation parts -- especially the
inheritance and virtual function stuff. i find the way C++ to be
overly complex and wordy. when i need a higher level language, i
reach for a higher level language which for me is less painful and
that'd be lisp.

Is there a linux software package for a "ppp-server"? I'm not sure if

modem for access to the internet, and set aside 1 or 2 normal modems to
allow someone to dialup to my little home network, and recieve an local

would be neat to be able to replicate what my ISP does when I dial-in to

In another thread, we have been discussing this. I experienced

Look into local echo and terminal type.

You are right. DECnet does it right and IP does it wrong. Having the
addressable communications endpoints be links rather than nodes has
wrought much pain over the years. (Consider the hoops that a UDP
server has to go thru on a "multihomed" [what a lame term!]
if it wants to have its responses go out with the "right" source IP
address.)
This is the price you pay for a protocol stack that was designed by
link-centric rather than host-centric folks. (On the other hand,
the benefit of a stack so designed is that IP has managed to
[more or less smoothly] scale to encompass the globe.)
~ <SS> Yes , more than one interface card per machine. Sorry I have not been
~ clear enough. But, what I mean is for eg, 2 ethernet devices ( eth0, eth1
~ active ) in one system ( physically these could be on one card or on multiple
~ cards ). I will check out MC-Gaurd, but the systems that I have seen provide
~ an IP failover capability, for eg., if by some detection mechanism you find
~ that eth0 failed , you now disable eth0 through some scripts and activate
~ eth1 with the same ip address that eth0 had. But this mechanism does not
~ provide for load balancing.
Some systems will support a virtual IP address. For example, Cisco
IOS allows you to create one or more "loopback" interfaces which
denote the box itself and not any particular physical interface.
We can then configure our IOS applications to use the loopback interface
address rather than one of the physical interface addresses - thus
the communications can load-balance across physical links, can
ride out link failures, etc.
I would think that a production-quality server operating system would
want to build in such a "loopback" interface. If you are using an
operating system that lacks such functionality, then you can work
around the problem by frontending your server(s) with boxes such as
our Local/Distributed Director systems (not a cheap solution however.)

What about mailbombing? Anyone good at that?

Just a guess, but check if you're editing /etc/passwd in another virtual
terminal or something like that. fuser /etc/passwd might tell you
something too. Does rebooting the system fix it?
