^^^^^^^^^^^^^^^
Are you talking about pinging the IP that shows up in the 'remote IP
address' log entry that pppd makes? If so, then you might have a
routing problem.
The PPP daemon creates two routes:
* A standard route to the remote IP
* A default route to the rest of the net, using the remote IP as its
gateway
If you're running pppd without the 'defaultroute' option, however,
only the first entry is created. Thus, you could ping the server just
fine (using the first route), but as the second route wouldn't exist,
the rest of the net would be unaccessible.
Hope this helps!

A nice description is included in "Linux System
Administrators Guide 0.6" (LSA) chapter 3 "Overview
of the Directory Tree". This work is part of the
Linux Documentation Project and the book is
probably on your system (in softform) if you installed
it . Check /usr/doc/LDP/ if it contains LSA.
My quotes come from this handbook.
By the way, it is not a good idea to cross-post to
so many newsgroups.
Merry Christmas.

Ethernet uses a pair on pins 1-2 and a pair on 3-6. phone stuff usually
uses the middle pair ( 4-5 on RJ45 ). I have run CAT5 cabling in my
house. I have every jack in the house wired with dial tone on the middle
pins 4-5 and 10/100 BT on pins 1-2, 3-6. I have a hub and router in the
garage that connect all this stuff together.
btw - ringing phone line is 90VAC - most ethernet cards don't like that.
get it right! :)

Well, I'm not *too* experienced at Linux LAN networking myself, but I
know I had a problem that baffled me a short while ago, and I can't
see anything wrong in your configuration, so I may as well post my
problem, and maybe it'll be yours as well..
You've got transmit and receive LEDs on the back of the cards, right?
If not, does the hub have flashing lights for when the nodes send
stuff? Watch the lights and determine if the cards are sending and
receiving. If they are, then try having the two machines ping each
other for a bit. Then, check the ifconfig's again.
If one of the machines' 'RX packets' counter is non-zero, then the
*other* machine might have an IRQ conflict with the network card. My
fileserver had a conflict between the NIC and the sound card, so it
could detect the card and transmit fine, but couldn't receive
anything.
If the RX counter is 0 for both machines, though, this probably isn't
the case (unless they *both* have IRQ conflicts, that is). Also, I'm
making the assumption here that your 'ifconfig' output was from
*before* you did the ping. If the TX counter is indeed 0 after
pinging, then I'm afraid I can't help, except to say that I don't see
any problem with your routing stuff.

Hi there,
is there a tool for Linux like the "Ping Plotter" for Windows NT, that
combines a simple "ping" with "traceroute" and giving a graphic output of the

This is a situation where the default route in the linux box should be set to
the routers ip address. After that it would be the routers job (hence the name router)
to put each ip packet on the correct interface. Sounds like the Linux box is OK,
but maybe the ISP's router isn't/doesn't know that the linux box is there ?

Thanks for all your help!
I hadn't installed imap but I have now and it works great with both POP3 and
IMAP.
My problem now is with sending mail. I can't send internal mail when my
system is offline, that is my gateway/router isn't connected to the
internet. Recieving mail works just fine. (Isn't much fun if you can't send
mail.)
My setup:
Server: 486/33 running sendmail, imap, named, apache, samba and much more.
Gateway: 386/33 running LRP, masquerade, pppd...
Clients: Winblows 95/NT with Outlook/Outlook Express.
I've figured out that the problem is with sendmail and that it want to
resolv names (DNS). I've got named installed and it works fine. ( I think )
Sendmail works just fine when the gateway is online but when it's offline
only POP3/IMAP works. I've edited sendmail.cf so all mailers is set to
expensive and HoldExpensive = True. This I got from the 'Linux Mail-Queue
mini-HOWTO'. Is there something I have to do besides restarting sendmail
(rebooting) that I have to do for the settings to take affect. What else do
I have to do to make this work? I'm completly lost on this one.

I did and :-)
So know I do not have to move this fat body into the spare bedroom to do
things on Linux since I can do it all from win98, will I be able to do
the same with machine freeBSD once setup?
I launched netscape & it works although it is complaining about fonts.
So where in netscape does one set it to access the net through win98
(10.0.1.250)?
Thanks for getting me this far:-)

Hi,
I use SAMBA to share a printer with W95 boxes, it works good.
But,
I try to connect a second printer (text generic for listing) using a
second parallel port on the linux box. I can share it with other linux
boxes.
I can install it on both W95 and NT4 but can't print.
The problem (my idea) is that in smb.conf the two printers share the
same generic spool directory : it works for lp but not for lp0.
If a make a specific paragraph for lp0 or for lp or for both I see just
one printer in the printer panels !!!
What is the problem ?

Make sure both nmbd and smbd daemons are running.
Make sure that inetd is not listening on same ports
does smbclient on the server see and accesss the shares?
What does your smb.conf look like. It is always a good idea to include it in
