Subject: NFS WITHIN AN IP MASQ FIREWALL
This may be an orriginal question and any help would be very much
appreciated.
Here's my situation. I'll draw a mapped diagram at the bottom to further
explain.
I have several machines connected within a LAN, and connected to the
outside internet using a linux box running IP-masq ( NAT )
The machines inside my lan, all run linux as well.
I am attempting to mount via NFS, to a machine on the outside internet.
The NFS server on the outside has, in it's /etc/exports file,
the ip number of the machine on my end, which is hosting for ip-masq
as rw,no_root_squash
I am able to successfully establish an NFS mount from my ip-masq box, to
the box which I wish to mount to.
Now... When I attempt to do a mount from within my ip-masq LAN, to the
same machine on the outter internet, it attempts a connection to
the outter machine, but the connection is refused by the outter machine,
due to the fact that ip-masq is assigning it an Illegal Port number.
I note this by the /var/log/messages file from the NFS Server which reads
NFS from xxx.xxx.xxx.xxx on ILLEGAL port number.
Here's a diagram ( I do better at most other things, but not well at
diagrams )
Inner Lan Machines
ipmasq box X <--trying to estab.
OUTTER NFS SERVER _____ | nfs to outter
|---|_____________________| |__________________| from these boxes
|---| |_____| |
X <---
If there was some way, I could convince NFS to assign say
perhaps ( and I'm guessing port # 2048 ) then I would be able
to connect from within the ip masq LAN to the outside.
Has anyone come across any solution to this.. or better yet, has anyone
been crazy enough to attempt this yet ??
Any replies to this please direct to my email account:

Thank you all in advance.

I have a machine that dual boots Win98 and Linux. The other day I got
a message from Norton AV that there was a change in the boot sector
and it wanted to fix it. Noth thinking about it I answere yes and it
overwrote LILO. Now I can't boot into Linux even with my boot disk. Is
there anything I can do to be able to boot back in to Linux? TIA.

I switched from SuSE 5.3 to Mandrake 5.3 (which is actually RedHat 5.2
with a bunch of the latest enhancements, and with KDE 1.1), and now I
know that SuSE is far and away the best distribution. Yast does things
for the system which Glint could only dream of. I'll be back with SuSE
before long!

Yes.. only linux has this weird name for it called ip-masq.
It works well... In some cases better and easier then
NAT under BSD.

Wrong wrong wrong.
Linux kernels do not come with everything installed.
Anyone who's going to learn unix ( sorry linux ) had better as hell
learn a little about c code and compiling the damd kernel.
If they don't we're going to end up with a mess of windows 95
users all over again.
Linux ISN'T easy to learn. It's still under development and
isn't something I'de suggest would be ( sorry ) plug and play.
Let them learn ! Let and make them learn how to compile a darn kernakl,
and let them have to re - install 15 billion times untill they get it
right.
I had to.. and very few people took any pitty on me what so ever when
I was learning this O/s five years ago.

Check the software that came with your cards, see if there is a DOS
configure utility. If there is , boot using a DOS boot disk, use the utility
to set card to what you want, then reboot linux. I have found the DOS
utilities for some cards is the only to get them configured correctly.

HI ALL,
I'm thinking of buying a four port hub and a couple of NIC's so I can
setup a Linux server w/Samba.
Netgear by Bay Networks has some good deals, but I don't know if their
products work with Linux. I'm running Redhat 5.1 - Intel, I read the
hardware list, but could not determine from the list if Netgear products
were supported or not.
If anyone has info on Netgear or any other economical solutions for a
small home network, please let me know.
Thanks
