Subject: ? loopback: ping `hostname`
Date: Sat, 08 May 1999 01:43:02 -0700
Hello, Everyone,
I'm trying to get loopback to work on a stand alone machine, called
"slackbox",
with no network card, running slackware 3.5 Linux. My /etc/hosts is like
this,
#/etc/hosts
127.0.0.1 localhost loopback
172.16.1.1 slackbox
`ping localhost` and `ping loopback` worked just fine, however,
`ping slackbox` FAILED with the error, "... network unreachable".
Can someone please enlight me on how to get this to work?
How do I let the computer loopback by referencing the hostname, i.e.,
ping `hostname`
-------------------
By the way, slackware 3.5 doesn't support `ifconfig dummy ...`.
TIA. Jianhong

Since I upgraded my Linux-PC with a second Processor
(Kernel 2.2.6 with SMB), the netatalk-kit won't work anymore.
If boot with kernel without SMB-feature, it works.
If I boot with kernel with SMB support; the atalkd
writes some error-lines in the logfile:
"atalkd: setifaddr: function permitted..."
"atalkd: child exits with 1"

Subject: Connect Linux box with Win95 using TCP/IP
Date: Sat, 08 May 1999 13:06:42 GMT
I am trying to connect a Linux and a win95 box using TCP/IP. However, I have
not been able to connect the two. Both machines have working ethernet cards
and have the correct drivers installed. I think my main problem is
configuring the Linux side. I have read the NET-3-HOWTO, but it hasnt helped
me. In anycase, here is how I set up the linux side:
ifconfig lo 127.0.0.1
route add 127.0.0.1
ifconfig eth0 192.168.0.1
ifconfig eth0 netmask 255.255.255.0
ifconfig eth0 broadcast 192.168.0.255
route add 192.168.0.0 device eth0
After doing this, I cant't even ping 192.168.0.1
Anyway, on the Win95 side, I have assigned it IP 192.168.0.2, and
assigned the gateway as IP 192.168.0.2. The Win95 box can ping itself but not
the linux box.
Can someone please explain what I am doing wrong? Thanks!

Instead of starting sendmail from /etc/rc3.d/init.d or wherever Suse
does it, start it in /etc/inetd.conf with a -bs switch and it will
receive mail from fetchmail but not from Demon.

Is it possible to get diald to dial different phone numbers, depending on
the destination address?
In other words, if I start up a telnet connection to a host at 172.16.1.1,
can I configure diald to dial a specific ppp configuration for that target
address, and another ppp configuration for anything else???

I am configuring a Mac II to do ip masquerading (which will pretty much
be its only purpose) to share my @Home connection. I am running the
Debian distribution for m68k, 2.0.36 -990223 kernel. I am have been
plugging away at this project for at least two months on and off; the
problem is that I can't find adequate directions for the Debian
distribution. I would erally appreciate some direction from people in
this newsgroup.
I think I can figure out the routing and IP masquerading, but the DHCP
configuration still escapes me. Too many of the documents refer to and
assume RedHat distributions. They either assume you have X running to
configure it or tell you to edit files in places that do not exist (it
seems) on a Debian machine (such as
/etc/sysconfig/network-scripts/ifdhspc-done). I tried to get X running
on my machine solely for the purpose of simplifying configuration; that
proved to have configuration problems too, which still have no
resolution (maybe upgrade the frame-buffer software--easy once it is on
the net!). I gave up on that and resigned myself to figuring it out
using a command line interface.
At this point I can have both ethernet cards be pinged over the network;
I can set up route to permit this. I could not make eth1 acquire an ip
using dhcpcd; I thought it was because the kernel autodetected only eth0
(I could enable eth1 from the command line using ifconfig), so I
switched all the references to make eth0 be the connection to the
outside world, and eth1 be the connection to the internal network (using
192.168.1.1). Again, this works and I can ping both cards; but only if I
have given eth0 a static address of 10.0.0.1. No way, no how can I make
eth0 get its address from dhcp. The dhcpcd config file has IFACE=eth0;
the material on DHCP at
http://metalab.unc.edu/LDP/HOWTO/mini/DHCP-3.html suggests that in the
Debian installation, that no configuration is otherwise necessary.
At the same time, assigning the ip that is currently being assigned by
the dhcp server using ifconfig--treating it as a static ip-- doesn't
seem to allow me to connect to the internet, even to test the
connection. So why doesn't it connect to the DHCP server? I need a
better reference that the man page for dhcpcd, or else some good
examples/directions from some of you good folks.

1. Start your xserver on the pc. You may need to configure it to run in
"Single window mode", or whatever.
2. Telnet into your linux box, login as your userid
3. set your DISPLAY variable: "export DISPLAY=pcaddress:0.0"
4. run your .xinit or /etc/X11/xinit verify these file locs first I
can't remember where they live.

I just installed RedHat 6 which does not have ipfwadm anymore. Apparently
there is ipfwadm-wrapper and ipchains modules to do the same thing. Has
anyone managed to configure the new modules to do what many of us do with
ipfwadm.
Here is my internal ipfwadm configuration to share a single modem with my
intranet..

You need an IMAP daemon. I use UW's software.
http://www.washington.edu/imap
I'm using it with the very same setup, running QMail and IMAPD on a RedHat
5.2 box, with Mac and Win clients running Outlook Express.
You just need to make sure that IMAPd looks for mail in the same place that
qmail delivers it to. For my site, I edited the imapd source (instructions
are in the documentatino with IMAPD), and use procmail for mail delivery,
and a .procmailrc to deliver mail to the same place I specified in the imapd
source. Two popular places are /var/imap/$USER/ or /home/$USER/mail,
depending on whether this machine mounts home directories via NFS. (If
/home is mounted via NFS, put imap mail in /var/imap/$USER)

I put some detector code in my firewall script and use a variable for either
IPFWADM or IPFWADM-WRAPPER.
My fragment looks like this:
if [ -e /proc/net/ipfw-chains ] # detect IPCHAINS in use
then
set IPFW = "/usr/sbin/ipfwadm-wrapper"
else
set IPFW = "/sbin/ipfwadm"
fi
Then you can use $IPFW in the rest of your firewall script.

They can, even with your setup. Try for a test:
1)
To telnet from any machine connected to the 10Mbps HUB into a machine
connected to the 100Mbps HUB.
And then start a telnet from that login to your 192.168.0.1. It works.
2)
To telnet from any machine connected to the 100Mbps HUB into a machine
connected to the 10Mbps HUB.
And then start a telnet from that login to your 192.168.0.1. It will
not work.
3)
To telnet from your linux bridge to any machine connected to the
100Mbps HUB.
And then start a telnet from that login to any machine connected to
the 10Mbps HUB. It works.

The bridging is transparent. For the machines connected to the hubs.
And you dont want subnetting or routing. OK. With that limitation i
rant on...
If you had "configured" both nic's at the bridge to 0.0.0.0 i am not
sure the bridge could have been reached at all. It becomes invisible.
Transparent for all other machines. Why not.
If you give the second nic a IPnr of let say 192.168.0.2, it does not
automatically help.
But if you then do an 'ifup eth1', voila, then the brigde is visible
and can speak to the machines connected that way.
And the other way is lost.
hmm..
So the problem is maybe how to be seen from all sides without any
routing. Maybe some kind of alias on the second nic will help. But
then i guess your machine will not know where to send replies. As
long as it seems like the last nic 'ifup eth*' is the one abel to
speak with other machines. (The bridging itself remains
undisturbed, you can 'ifup eth1', and test, and so 'ifup eth0' and
test.)
So i dont know. If you give both nic's the IPnr of 192.168.0.1 i
wonder what happens.. It might work, but strange things may happen ;-)
man arp
man tcpdump
(and if you have enough nic's to experiment with; And dont mind
playing; the result may be confusing (at best?).
Configure the two nic's (eth0, eth1) already in your machine to
0.0.0.0
Put another nic (eth2?) into the linux box, and give it a IPnr, say
192.168.0.1, and do _not_ bridge that nic. Connect that nic to any
of the hub's.
Start the bridge. (on eth0 and eth1)
Do a 'ifup eth2' on the nic to be 192.168.0.1
I guess that will be the way out for your linux box, and i guess it
will be reached from all sides. Not very economic. I guess traffic
to your machine then will go (in a loop) from the machines connected to
the other HUB, trough the bridge, to the hub, and then to your
192.168.0.1.
I dont know if it will work. If you use the 'bridgex-0.2' turn on
debug. Listening after arp-request with tcpdump is also informative.
with luck the eth2 is found as 'just another nic' connected to the hub
and learned by the bridge that way.)
I once placed two linux-bridges back to back, eth0 to et0, and eth1 to
eth1, crossover tp. And it generated a lot of traffic... I dont do
that anymore..
