Re: [leaf-user] can only ping assigned IP

[Ray Olszewski]

The project name these days is LEAF, not LRP. I do note that EigerStein 
plus Trevor's PPP dialup package is pretty old stuff, possibly tough to get 
current support for.

As to your substantive problem, I see a couple of oddities in what you 
posted. First, the pppd messages never report receiving a local IP address 
for ppp0, but do report this entry:

Jul 12 10:31:31 firewall pppd[735]: Remote message:
Jul 12 10:31:35 firewall pppd[735]: Remote IP address changed to
206.166.57.162
Second, your routing table offers this oddity:

206.166.57.162 dev ppp0  proto kernel  scope link  src 12.34.56.78
The "12.34.56.78" part suggests that you are not getting a proper local 
address assigned to the interface. SInce both local and remote addresses 
are usually logged by pppd, the two oddities are at least consistent.

But this leaves me a bit puzzled about what IP address you are referring to 
when you say you can ping "ONLY to the assigned IP my ISP gives me". Do you 
really mean "12.34.56.78", or do you mean some other address (which implies 
some error in what you reported to us)?

It might help if next time you included the output of "ip -v link show" so 
we could see what interfaces are active and what packet counts they show.

As to the pings, how do they fail? Do they fail silently, or do you get one 
of the many possible error messages? Details count here for diagnosis. And 
you mention ping'ing (unsuccessfully) addresses "including the DNS servers 
or other IPs or names". What about the other end of the ppp0 link (in the 
example you reported, 206.166.57.162)? Until you can ping the other end of 
the link, you will not be able to ping anything past it.

One thing you **might** want to try: change this line in /etc/network.conf

                                # External Address dynamically assigned
EXTERN_DYNADDR=NO               # - YES/NO
to read YES.

If none of this causes you to spot the solution on your own, please post a 
followup with this information (don't edit, please, and include the command 
you enter, not a replacement header as you did this time) when the ppp0 
interface is up:

        output of "ip -v link show"
        output of "ip route show"
        the log output of "pppd" only after "chat" finishes logging
Also provide the equivalent information for your Slackware system when it 
is working. That might be the same commands or it might be

        output of "ifconfig -a"
        output of "netstat -nr"
        the same pppd output

I'm into a blind cove and close to the rocks.

I'm struggling to set up LRP and have partial success.  I cannot ping to the
outside world.  ONLY to the assigned IP my ISP gives me.
Using ppp0 --> outside; eht0 --> inside

I get no error messages in /var/log/messages or /var/log/ppp.log

Get perfect success when I ping the assigned IP.  Likewise, I can ping any
internal machine on my LAN.  Nothing when ping ANYWHERE else outside,
including the DNS servers or other IPs or names.  The "SO" modem light blinks
merrily, but no one is talking back.
Details:
Hardware: Pentium 75/133, 48 Mb RAM, USRobotics 28800 (old) modem, ne2000 NIC
OS: Charles Steinkuehler's EigerStein_1_img_EigerStein.exe with dialout.lrp
from Trevor
Things tried: removed any (and ALL) references in --> /etc/hosts.deny  -->
/etc/hosts.allow
Changed modem configs to several types: ATH0, AT&F1, AT&FH0, etc
It's clear I'm connecting fine, just my ISP is blocking me somehow.  BTW, on
my regular Slackware 9.0 box I have absolutely no problem (setup with
'pppsetup').  I can connect and ping and surf everywhere.  I have built
/etc/ppp/options and /etc/ppp/chatscript to look exactly like my working box
which works.  Hmmm?  (that's circular)
So, here's hoping someone with a quick look can pinpoint my mistake.  After
much frustration with other LRPs, this version is tantalizing close to
talking to the outside.  Thanks.

ps: I looked through "Re: [leaf-user] Can't ping external gateway" thread 
from
Sept 2002.  This seemed to be slightly different.  Yes?  No?

So here is all those details the help page requested.  I'll strip the 
filler.
Hoping all of this is helpful
