Never mind. Someone pointed out to me that the file is
already in plain text format, despite the .gz extension.
And the webmaster at www.moretonbay.com has already get rid
of the .gz extension on that file. Thanks everyone.

Before going any further, make sure your DNS actually works OK. Go to
/etc/resolv.conf, and input the IP address of the name server, then
ping with a name instead of an IP. If this works, then it appears that
the DHCP is not sending the IP address of the name servers correctly.

A lot of people are working on this, since it's a real pain to have a
mix of dynamic (DHCP) and static (DNS) tools. The reason DNS is
static, is that computer networks used to be mostly available in big
organizations, where you wouldn't hook up new hosts every other day,
hence no need for an automatic update.
Since any DNS domain on the Net is required to have a primary +
secondary servers, making DNS updates automatic would only generate
more traffic (between the primary and secondary, and also updates on
caching-only DNS servers.) There may be other technical issues that I
don't know about, though.
To make it a bit easier to keep DHCP and DNS synchronized, there are
graphic tools, some web-based, like Linuxconf or Webmin
(www.linuxapps.com for more.) ISC working on a dynamic DNS, but it's
still under development (www.isc.com).
Hope that helps,
FF.

Hi
I was trying to install two NIC cards on my system which is RedHat 6.0.
I have put following lines in my lilo.conf file
append="ether=5,0x280,eth0 ether=10,320,eth1"
I could easily configure one to connect to my ADSL connection.However I
can't do same with other NIC card.
When it boots up
it gives a meesaage ".....delaying initialization".
then it reports fail
However I can't see similar message when I do dmesg | more
when I try to run ifconfig. I get message
SIOCSIF........:No Such device and couple of more messages with similar
content

when I give command ne3k -p 320 I get following output

Internal or external modem? You probably need isapnp if you have not
installed it. Then do a 'pnpdump > /etc/isapnp.conf' and edit that for
suitable port and irq. RedHat automatically runs isapnp if
/etc/isapnp.conf exists. Of course if you have any other pnp equipment,
you may want to back up the conf file first.

want the RH6.0 machine to provide SMTP, FTP, telnet, and DHCP servers to the
interal network. I have everything working correctly, but how do I NOT
offer these services to the rest of the Internet (i.e. how do I force these

Probably write and excute permission on /tftpboot. You need execute

Hello,
I have connected three PC with an Ethernet cable, two with Windows and one
with Linux (RedHat 6.0 kernel 2.2.9 connected via ppp to internet). which
is configured to give to the others PC access to the web (with ipchains
and squid), to the news off-line (with leafnode) and to the mail with
sendmail and fetchmail/procmail.
I have created a private domain and sendmail is setup to transform email
address correctly.
I have a problem on Windows when an user send a email off-line to my linux
server, here is an extract of the log file (tavel.mondomaine.fr is the name
of my linux server, shuttle is my PC with windows):

The email is rejected and doesn't appear in /var/spool/mqueue.
I have no problem when I send a email from a PC with windows when my linux

Does anybody know what does "Lost input channel" mean and come from ?
Please, send me by email a copy of your answer.

Where the packets go depends on the routes. You could always firewall to make sure but
they shouldn't if everything is setup corectly.

Even with the permissions for /tftpboot set to 777 it won't create a file,
only write to existing files.

See /usr/doc/HOWTO/mini/IP-Masquerade or something similar. You cannot
simply connect your LAN to the internet unless you have IP's assigned by
your ISP and proper routing.
Also make sure you do not have a default route to your LAN. Otherwise the
defaultroute option for pppd will not work.

As a relative Linux newbie myself, I found it much easier to do
things with the command line interface, especially when setting up
things like IP Chains and such. It's much easier to type along with
the instructions that trying to describe points & clicks in various
menus and selection boxes.
Another problem with Linux GUI is that it's rapidly changing.
Describing how to change a file's attributes via Gnome's MC might be
fine for this year, but what if they change the menu structure? And
what about KDE users? It's doubtful that chmod will change much in
the next few years, though.
When I started learning Linux and bash, some of the manuals I d/l
were several years old; a few were for other UNIXes. Even though
they were dated, the information they contained was still very
useful, because user interaction via the command line has changed
very little the past few years.
Newbie documentation sure wouldn't hurt, but don't overlook Linux's
strongpoint: a robust command line interface. Sometimes it is the
EASIEST way to get things done.

When you run route -n, you will find a line starting with 0.0.0.0 and ending
with eth0
Taht is the default route. Your ethernet should NOT have a default route
set on it. remove it. ( eg
route del default
as root before you run ppp, -- eg at the end of /etc/rc.local)
