Determine if it is a hardware or a network configuration problem by
running ifconfig. You should see the device listed as something like eth0.
If it is there you will also see the IP assigned to it. If it ain't there
then you probably need an alias in /etc/conf.modules (RedHat specific YMMV)
or an append line in LILO. If it is there then check your IP info; gateway,
routing, etc.

Hi there,
My dialin is working.. I can listen it dialing, I can see
the sislog messages and everything is ok... the final of the file is :
May 31 00:09:07 valner pppd[156]: Using interface ppp0
>May 31 00:09:07 valner pppd[156]: Connect: ppp0 <--> /dev/ttyS2
however, I'm not connected... and the final words from the ISP didn't
come... so I've take a look in the route table and I just see the eth0
interface...
I tryed to type the command line:
route add default ppp0
and I got the error message
SIOCADDRT: No such device
ppp0: unknown interface
Well... I don't have idea how to setup that... (ifconfig??)
any suggestion is welcome.
Thankx
Valner

Is 192.168.0.132 Hostname.xxx.yyy in your hosts file?
Is the hostname.xxx.yyy in your resolve.config search ??
Is your domain also on the search line in resolve.conf ?
I don't think numbers ar allowed as domain names (706).
Here's my resolve.conf

Nicht mal Netze. Topologieinformationen. Daraus wird in jedem
Rechner (im Prinzip jedenfalls) ein Abbild des Netzes abgeleitet,
aus dem dann Routingentscheidungen abgeleitet werden.
Das hat insbesondere den Vorteil, dass einzelne Ausfaelle als solche
richtig in die Topologie eingearbeitet werden und moegliche Ersatzwege
in kuerzestmoeglicher Zeit von allen Routern gleichzeitig beachtet werden.

Bernd hat einfach den Begriff Internetworking nicht verstanden ;-)
Wenn wir keine Internetworks haetten, braeuchten wir keine Router.
Nebenbei brauchst Du nur 5 Minuten Real-Netz, um wieder zu wissen,
wofuer man Router braucht. Die normative Kraft des faktischen holt
Dich in Form von IP-Broadcast-Domains und Windows NT massiv
wieder ein.
Ob die Router dann zwischen realen Ports oder zwischen virtuellen
solchen hin und her routen, ist eine zweite Frage.
Aber Leute, die meinten, in stark frequentierten NT-Netzen
die goldene Regel von maximal 30 Rechnern pro IP-Segment ueberschreiten
zu muessen, haben meistens sehr schnell gelernt, was eine
Heavysidesche Sprungfunktion ist ;-)
(Ich will jetzt aber die zugehoerige Definition nicht aendern,
nachdem sie Lutz so schoen veroeffentlicht hat :-))

The files in /var/tmp/.pop. Sometimes, not always, when a user gets his
email via POP3. It puts a file with his username on it in that directory.
The file contains his messages. On the client end, the check locks up and
he never gets anything.
What is that directory for?
Why is he not getting anything?

The workgroup name is actually in smb.conf. Change this to the name of your
LAN workgroup, restart samba, and your linux box will appear in the Win
network neighborhood.

You may want to start here, there are pages before this but it
seem like this is where a good example and explanation would
take you. Get them talking then work on the firewall.
Perhaps proxy arp may be of use in your configuration.

I am running a LAN with a linux box being the server, running IP

Hello,

Both are connected to a network. One card works fine,
but the second card gives

I tested both cards with the 3com echo test
and then they work fine.
Can someone please help me?

Subject: DHCP? Automatic Routing info?
Date: Wed, 2 Jun 1999 15:29:22 -0400
I used Linuxconf to set up the routing information so my machine works,
but I thought all that stuff got taken care of automatically, maybe
through DHCP or something. It did on a different machine, using RH 5.2, in
a different room of the same building. In all my previous installations of
Linux, I never had to set up any routing info. What's the deal?
I've got a box running RedHat 6.0 that I just installed. It has a 3Com
Etherlink XL TPO (10Mb) card.
For all those who sift the newsgroups for help, these were my symptoms and
the solution I used. I'm posting them because I didn't find this info when
I searched dejanews.
Symptoms:
I couldn't connect to any machine besides the machine NT Box next to
it on my desk, as both are plugged into the same hub. Thn NT box could
connect to my Linux box. I couldn't connect beyond the hub with the Linux
box. When I tried to ping anything else it said "Network is
unreachable". The Linux box couldn't even connect to what the NT box says
is the gateway.
Solution: Get gateway/routing information from NT machine by "route print"
from MS-DOS (if the gateway address is the same for anything but the 127.*
address, replace it with the gateway address for 0.0.0.0 address/netmask).
"nslookup" will give the DNS IP address.
For 95, Get these from 95 via winipcfg. (you can also see the DHCP and DNS
this way.
Use Linuxconf to configure the DNS, gateway and DHCP for linux.
