First, a suggestion: Dont shout. ALL CAPS has the same effect as
shouting
and most people get upset at messages that are shouted at them. Try
posting
in mixed case, as you would write a letter. Use ALL CAPS sparingly,
reserving
them for the most extreme emphasis. If a little emphasis is necessary,
use
_underscores_ or *asterisks* to quote the stressed words, please.
Now, to your problem...

This garbage likely is the PPP protocol data. Examine your login script
to see why
it's not releasing back to pppd when this datastream starts. If you need
help,
post the details (your login script, pppd parameters, etc.).

Of course you get the "No Carrier" message, you haven't responded to
your ISP's
PPP stream, and they timed out your connection.

Show us your scripts, and perhaps the section of your /var/log/messages
at the time you attempted to log in. There's not much we can help you
with
without those.

Hi,
When my ISP is not yet using PAP I have no problem connecting to their ISP
but when they shifted to using PAP, I cannot complete my connection.
What I did was just delete the part with my specifying my
username, password & the command which will start ppp like the ff:

My installation is Slackware3.5 with kernel version 2.0.34 installed on

Subject: PPP excessive logging
Date: Wed, 05 May 1999 23:14:32 -0400
I have absolutely no idea what's going on. I have a (very) stock debian
2.1 box setup as a masquerade router. I'm running kernel 2.2.5 with
pppd 2.3.5. For some reason the kernel seems to be logging EVERY SINGLE
ppp packet in /var/log/kern.log, messages, and ppp.log. The -debug
option is not set when pppd is run, and the ethernet packets are not
logged. Following is a snippet of what is in the logs:
May 2 17:03:35 zaphod kernel: ppp: receive frame, count = 56

I want the connection to stay up, but I want to know when it is up
and not busy.
Is there any built in instrumentation to determine how many active
TCP connections are open over the link?
(The code that does VJ Header compression should know this)

I have the same problem. Slackware-3.4 with a linux-2.0.36 kernel on
a 486 with two Kingston (tulip) NICs (but only one hooked up to my
hub). I'm doing IP Masquerading as well. The lockup seems at random,
but can take up to three weeks to occur.
I can "correct" the lockup by going to the console, and doing:
# ifconfig eth0 down
# ifconfig eth0 up
# route add -net 192.168.1.0 netmask 255.255.255.0 eth0
Sounds like we have a common problem. My post last week drew no
response.

What I'd do (maybe not the best thing to do), is write a script that is
cron'd every 5 minutes or so.
Take the output of 'ifconfig ppp0' or 'pppstats', parse it for the RX and TX
values, save them to a file, then compare those values to the last time it
ran, then you know if the link is idle.

Subject: IPX routing over ppp
Date: Thu, 6 May 1999 00:46:24 -0400
Hi,
I've already been all over deja news and the How-To's for this one. I
cant get a working solution. I'm trying to route IPX between two networks
through ppp so that DOS clients on the remote subnet can log into a Novell
server on the local subnet. Here's my situation:
I've got two identically configured slackware Linux boxes dialing in to each
other and properly routing IP between their subnets. I've got IPX working
and can see the following in an ifconfig:
eth0 Link encap:Ethernet HWaddr 00:C0:F0:1C:53:9E
inet addr:192.168.138.254 Bcast:192.168.138.255

But I'm not sure what network addresses to use to see my Novell server
across them. I copied the addresses off the Novell server for the host
Linux box and made up addresses for the remote. I'm using the ipx internal
network option in the kernel. I've got the ipx_interface and ipxd compiled
and working as specified in the IPX-HowTo. Still not routing, though. I'm
sure part of the problem is that I know nothing about IPX routing theory.
Any tips?

Subject: inbound IP Forwarding to private IP?
Date: Tue, 4 May 1999 22:15:24 -0700
Hi
I'm trying to set up a RH 5.2 box as a firewall for a network of private IP
addresses. It's a pretty standard configuration (eth0=external_addr;
eth1=internal_addr), using ipfwadm. Forwarding and masquerading are turned
on. I can get out of the private network through the firewall with no
problems. Outgoing IP forwarding is working swell.
What I would like to do is to forward all requests coming to
external_addr:80 to some_internal_addr:80. In other words, give outsiders
access to a web server(s) running on the internal network. This seems to
not be working so well.
Most of the faqs I've found deal with all routeable addresses, so I'm
wondering if I'm trying to do something that ipfwadm cannot do on its own.
i.e., I've not seen examples that deal with forwarding into (as opposed to
out of) private IPs.
How do I specify that requests coming to external_addr:80 should be
forwarded to some_internal_addr:80, where some_internal_addr is not on the
firewall machine?

Reply-To: [EMAIL PROTECTED]
Thanks for your reply.
I would be running squid on that linux box. Thats not a problem. Even having
two networks on two interfaces [eth0 and ppp0] is not a problem. Its quite
normal and simple.
Problem occurs when my DNS [the same linux box] resolves my domain to that
static /24 IP [while requesting clients are on /16.] For example, on my WinNT
workstation, whose DNS is 192.168.1.1, I do a nslookup www.mydomain.com. This
box goes to my DNS [say 192.168.1.2] and queries www.mydomain.com. That DNS
says it is on 210.x.x.x. Now, that WinNT client can not, ofcourse, connect to
that box [different networks!] This is what I am willing to determine. Will I
use a route that says that for anything 210.x.x.x default gateway is
192.168.1.2?
Although running two name server on this linux box, both listening to
different interfaces and resolving names appropriately, will resolve the
problem but I am looking for alternate ways to do this. E.g. to add routes
without adding an additional process [named in this case.]
