This is not quite true, by default,it will not relay nor accept any connections.
in.popd also refuses to operate by default... Alot of setup is required

What do you use to connect the modem to the server mgetty getty?
How do you want to authenticate pap chap or shell?
Can you login when you use the pre connection terminal (you will get the
linux shell)?

Date: Sun, 22 Aug 1999 01:27:35 +0200
The problem is not the ftp server nor masquerading.
The problem is the masq_ftp module that will take care of masquearding
ftp requests.
FTP is a protocoll that uses 3 sockets (connections) to port 21 one for
auth one for listings (like your directory) and one for up and
downloads.
The ip_masq_ftp mod is probably hardcoded for port 21 you should edit
the ip_masq_ftp.x file to do this trick on your chosen port. This is
cumbersome since then it will work to your ftp server somewhere on the
net but it won't work for other servers.
I suggest leaving your FTP server on port 21 (where it suppose to be).
You will not improve security if you think that. SInce any port scanner
will scan your system and find it anyhow.

Subject: Routing blues.....
Date: Sat, 21 Aug 1999 18:30:34 -0400
Getting a "Resquest Timed out" message when I attempt to ping my firewall
from an NT client.
My topology consists of several NT workstations and a router all
on the same subnet (192.168.1.0). The router is a dual homed linux
box which is also connected to a firewall.
NT Boxes

I'm assuming it has to be the router because I'm able to ping the firewall
when
initiated from the router.
Some stats...

Not only did I implement masquerading on the firewall, but set it up on the
router
as well. Thought this might give me and extra level of security.
This is how I'm initializing masquerading in rc.local on the router

You find this strange?
Its not since 99.999% of the service are build for ipv4 and don't know what to
do with ipv6. This is the whole problem with IPV6 at this point. SOftware
needs to be rewritten (the least terrible part) but what about all the
hardware routers, access servers, switches etc etc etc
SO I suggest you use IPv4 untill IPV6 is common enough to use it.

be sure that your ip_forward is set to yes.
echo "1">/proc/sys/net/ipv4/ip_forward
ipchains -A forward -s 192.168.0.0/24 -d 0/0 -i ppp0 -j MASQ
Or if you wanna keep it easy ipchains -A forward -i ppp0 -J MASQ
This should do the trick.

Yes you can. Before I had Linux this is how my partner & I used to share one
internet connection from two PCs. My NT 4.0 workstation was the gateway.
There are problems though. The first is that you need to run proxy servers
on the NT box. This means that you need to find the servers, download &
install them, then you need to configure the software on the client box to
use the proxies. For any Linux software which doesn't have proxy support
built in you will need to recompile with a library (e.g. socksify) which
converts native network calls to proxy ones.
After quite a bit of mucking around I found that the socks server from NEC
was the best free server for my needs. It seemed to work well, but it had
two annoying problems. First there appears to be a memory (and system
handle) leak in it, and every few days I needed to shut the server down and
re-start it to recover the used handles.
Secondly it didn't like working if it was brought up too soon after a
reboot. So quite often following a reboot I needed to manually stop it and
restart.
Another problem is that to allow users to start/stop the service I had to
hand out administrator privileges (more or less equivalent to root) on my
workstation to the other family members ... even though I trust them not to
do anything malicious, there was always the risk that they would have an
unfortunate accident.
In general terms our experience of using NT 4.0 WS as a gateway was that
with a lot of effort -- both initial, and on going -- you can make it work.
Configuring Linux to be my dial-out gateway has proved simple and robust.
I've used IP masquerading and wvdial and it all worked first time as
described in the how-to and man page. No software reconfigurations on the
client machines, no problems finding compatible products, and no
administrator access to the NT workstation for other family members.
If using your Linux box as the dial-out is an option I would stongly
recommend you do it that way.

Subject: Samba File Server - Mount Local?
Date: Sat, 21 Aug 1999 18:31:46 -0500
I use one of my machines as a file server using samba. I also use the file
server machine for a few other tasks once in a while. Here is my question:
Should I mount the samba shares locally if I need to work with shared files
or would it be safe to just open them directly? In other words, let's say
I have a directory on the file server called "Documents" that is shared.
Should I locally mount that dir even on the file server itself if I want
to work with the documents in there or can I just make a symbolic link or
whatever and open the files in there directly? The reason why I am asking
is, I remember reading about lock files, exclusive access, and other
related things. So I was figuring it might be safer if I handle the access
to the shared stuff even through samba on the file server machine itself.
But then, on the other hand, this is adding some additional overhead that
might not be necessary.
Comments, suggestions, tips? Any help is appreciated!

Don't you want to do recursive queries?
You can switch of recursion in the named.conf file. This should be done
since this way your BIND server is'nt volurnable to dirty caching.

First of all, I would kill your provider if I were you. They don't want
you to run your own webserver/smtp etc etc etc. They probably will open up
those ports when you pay them. Sonce of bitches thats what they are.
Yes there is the possibility to change portnumbers but that won't help you
alot. Since all the other smtp servers in the world wil send there message
to port 25 and since your server might be listening on 1666 f.e. it will
not drop of your mail.
I suggest a nice and polite chat with your ISP.

Hello,
does somebody know if it's possible to configure my system (using one
(!) AVM FritzCard PCI) so that one channel can be used for dialing in
(e.g. from home to my office), while the other So is used (at the same
time) to dial out and connect my office net (and me at home as a
point-to-point member of my office net) to the internet?
To me this means (at the moment) that I have to configure the ippp0 an
ippp1 that way, that they use the same hardware (only one Fritz-Card)
Thanks in advance
