I think you also need to set up IP forwarding. Actually I don't understand
the difference between masquerading and forwarding (anybody?) but there's an
excellent Linux Gazette article which explains how to set this stuff up at
http://lg.forcetech.com.au/issue26/kunz.html
The forwarding they describe and that works for me in my startup scripts is
#!/bin/sh
ipfwadm -F -f
ipfwadm -F -p accept
ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0
BTW - as of kernel 2.2 IP forwarding gets replaced by IP Chains. I haven't
dared try that yet!

I have proftpd installed on Redhat Linux 6.0. I wish to assign specific
users to specific directories and restrict them from going up from that
directory (they can get to folders within the directory). For example I
would like to have user "jack" when connecting put in /home/http/jack and
have access to all folders in that directory but not above it. I find the
documentation for proftpd rather cryptic can anyone help?
Thanks,
Bob

Subject: direct ethernet + PPP backup
Date: Mon, 26 Apr 1999 16:49:30 GMT
I've searched through the postings, but am still
a bit in the dark. here's my setup:
linuxbox (2.0.36) with two nics and modem.
eth0 has valid ip, w/ direct internet acces.
eth1 is 192.168.1.1.
our win95 clients have valid ips, 207.197.211.x, and
private, 192.168.1.x. to make things simple,
we're keeping the valid ips for VNC's from outside, and
private addresses for masquerading whenever necesary.
if our direct access dies, i'm trying to route
192.168.1.x, via ip masquerading, through a ppp dial-up.
i've establsihed a ppp connection, but how do i force
masquerading to use the ppp0 device? recently our isp, verio,
had probems and we were left for a couple of weeks w/ intermitent
access. at the very least a ppp link would have allowed our
staff to check their mail....
any ideas?
TIA,
Bill

Subject: Re: How use route command?
Date: Mon, 03 May 1999 04:39:08 GMT
Let me restate my problem, as it may have been ambiguous in my first posting.
We are trying to configure the client, not the actual gateway host. I.e., we
are trying to configure the client at 192.168.1.1 to use the gateway host at
192.168.1.100 as its default gateway server.
Here are the full instructions given in the book:
/sbin/ifconfig eth0 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255
/sbin/route add -net 192.168.1.0 netmask 255.255.255.0 dev eth0
/sbin/route add default 192.168.1.100 dev eth0
My question: is the last line a syntactical error or a variation of the more
common format of the route command, "/sbin/route add default gw 192.168.1.100
dev eth0" ?
(Although I have tested this command for myself, I cannot atest to the results
in other platforms, versions, and/or environments).
Thanks to all.

This was pointed out by somebody some time ago and I also explored this
a bit. It affects TCP ports, as is readily verified by using
ServerSocket in your code.
I wrote a "C" program which demos this, showing that it is not an oddity
of Java, but the OS (?).
Never figured it out.

Hello
I am using the xterminal kit from

on a RedHat 5.2 Linux server, kernel 2.2.6.
I get the following message when starting X on the client
with /bin/xgo:
Cannot open mouse (Device or resource busy)
I removed gpm on the server to no avail.
I tested the client mouse under DOS on the same machine,
works fine.
So I am now sure this is a configuration/software problem.
But after one day spent tracking it, I made no progress,
so I'll be much grateful for any help ;)

But I can't split the stream with two streams....
I have the route table with 2 NICs like this...

203.239.62.0 255.255.255.0 eth1
and,
eth0 : 203.239.62.111
eth1 : 203.239.62.112
But, all stream goes out through eth0.
How can I spilit the stream by two in same subnet?
