Hi,
I have ppp up and working as a gateway from my network to an ISP. I
have a static IP number and am hosting a web site for my company. No
problems at all; it works great. I do have two questions however...
1. How do I get my modem to reconnect when my ISP drops me?
2. Is there anyway I can find out info about my connection- connection
speed, bytes in, bytes out, duration of the connection, ... ?
I am using Slackware with Kernel 2.0.36.
Thanks for the help in advance,
Ben

The equivalent chat expect/send would be
'ts>' ppp
or perhaps
'ts>' ppp\\r
since I'm not sure whether a carriage return is sent without a \r .
The quoting is necessary for the ts> prompt because > is used
for shell redirection.
The `~' expect/send in your current chat script may be unnecessary, but
the new one above should either be inserted just before it, or should
replace it.

I've never seen linuxconf, it wasn't around when I started with Linux PPP.
The /ect/ppp files aren't applicable to chat scripting although there is
usually a /etc/ppp/scripts where ppp startup scripts can be found. These
are not universal and can vary from distribution to distribution.

I'm having similar problems. I get the message about protocol 0400 being
buggy -- that's the only message I get, but I get it a lot. This started
happening after I moved to kernel 2.2.3 with netatalk 1.4b2+asun2.1.3, both
straight out of the RPM. (I tried compiling the source also. No luck there
either.)
Ever since this started happening netatalk has refused to see my AppleTalk
network, telling me I'm basically my own little one-machine network out
there. Interestingly enough, ADP over TCP/IP works just fine. I can't see my
machine in the chooser on a local Mac, but then again I've never been able
to get that to work yet, even back when I was seeing things like zone lists.
Any help would be welcomed. Thanks in advance.

Have a look at http://www.wolfenet.com/~jhardin/ipfwadm.html
It's a GUI around ipfwadm, and there are instructions for setting up a
dynamic-IP firewall if you follow the "Invoking the firewall script" link.

Subject: Slightly Off Topic?? Cisco 2511 and Packet Filters?
Date: Fri, 12 Mar 1999 10:24:48 -0700
Hi, I know this isn't totally concerned with Linux
but I hope someone else has run into the same thing
as I have.
We are running two Cisco 2511 routers with USR
MP 16 modem pools. We are also running three
netserver 16 units. We authenticate with Cistron
Radius. I need to figure out how to set up packet filters
on the two Cisco units, the documentation isn't exactly
the easiest to navigate.
With the Netservers the filter creation is a simple process.
Any Ideas

Subject: IP Masquerading & mrouted
Date: Fri, 12 Mar 1999 13:03:44 -0800
I am setting up a new tunnel to the mbone, so I am installing mrouted.
That in itself is easy.
I would like to know beforehand, if ip masquerading will affect the
multicast packets?
The machine I am installing mrouted on, is masquerading packets for an
entire intranet, and I would like to keep it that way, without any major
changes...
Anyone have any thoughts on this?
Thanks

Hi all,
I have a 2 PC setup home network setup on which both PCs were running
Win95 and sharing a DSL connection using Wingate as a proxy server on
PC1. This setup worked well for a while but it seemed to be getting
less and less stable, until last Saturday something on PC1 got corrupted
by a blue screen of death and I was unable to reconfigure networking to
again work.
To make a long story short, I dumped the hard drive of PC1 onto PC2 and
installed RedHat 5.2 on PC1. I've spent this week trying to figure
everything out and have made some good progress I think, but I am not
where I need to be yet. Right now, I'm set up so that either machine
can use the DSL line by switching the plug from one to the other.
PC1 is a P150 with 96mb ram, 1 gig HD, 2NICs (3C509B and NE2000) which
are both now working. I have a static IP address for PC1 which is
assigned to the 3C509B and the NE2000 is 192.168.0.1. The static IP
address has a name to go with it assigned by my ISP
(dsl-southpaw.abc.primenet.com). Does this have to be PC1's name as far
as linux is concerned?
Do I need to use some little name for my private network like
mynetwork.com?
Should there be a name affiliated with 192.168.0.1?
Where do I need to go in order to replicate the setup I had using Win95
alone? I played some with samba going but have not yet succeeded in
using it to access PC1 from PC2. I have downloaded the latest RPM for it
and installed it but haven't yet gotten it configured. The physical
networking is ok, as I can ping from one to the other just fine (On the
Win95 PC it only works if I ping by number), but that's about all I've
been able to do so far.
What else will I need to do? Scanning the messages here it sounds like
I need to set up IP Masquerading. Or is there separate proxy server
software I should use? What about security as well. Someone sent me
towards squid but that looks to me like a web caching program, is that
right?
I'd be grateful for whatever pointers you all can provide, thanks a lot.

Since I find networking similar hardware/OSes not very interesting, I
tend to name things by hardware/OS. My home currently has:
amiga (Amiga A3000), macos8 (PowerMac 7200), linux52 (Cyrix 6x86-PR200+),
sco505 (Cyrix 6x86-PR200+), and win98 (Cyrix MediaGX)
I'm hoping to add solaris7, but I can't get the damn thing to boot once I
install it.

Subject: cannot add route to local host through loopback
Date: 12 Mar 1999 19:17:44 +0100
Dear Gurus,
I recently upgraded from RHL4.1/2.1.24 to RHL5.2/2.2.3 (with the very
latest net-tools RPM, pcmcia recompiled from current sources, etc.)
and can no longer configure my local routing correctly. I use PCMCIA
to run a 3Com564D net/modem card, and I'd like the machine to know how
to route packets to its real inet address even when the card is
absent.
By default (with no network card inserted) I have the loopback route.
When I ping the real inet address I get the usual "network
unreachable".
Previously I was able to run a static route through "lo" to my
machine's actual inet address:
route add -host 128.93.52.7 dev lo
This used to make the ping to the real address work. (For various
reasons I have to run X to this address, so this is a very necessary
capability for me.)
Since upgrading this no longer works. "ping" sends the packet, and
then sits waiting for a response that never arrives. What's even more
bizarre is that the output from ping implies that the sender field in
the packet is not being set correctly.
After the above route command I have:
Destination Gateway Genmask Flags Metric Ref Use Iface
clotho.inria.fr * 255.255.0.0 UH 0 0 0 lo
localhost.inria * 255.255.0.0 UH 0 0 0 lo
(the contents of /proc/net/route imply identical gw/flags/iface too).
When I "ping -v -d -R -c 1 localhost" I get something reasonable:
PING localhost.inria.fr (127.0.0.1): 56 data bytes
64 bytes from localhost.inria.fr (127.0.0.1): Echo Request
RR: localhost.inria.fr (127.0.0.1)
localhost.inria.fr (127.0.0.1)
64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=3.2ms
RR: localhost.inria.fr (127.0.0.1)
localhost.inria.fr (127.0.0.1)
localhost.inria.fr (127.0.0.1)
localhost.inria.fr (127.0.0.1)
--- localhost.inria.fr ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
When I "ping -v -d -R -c 1 128.93.52.7" I get something that appears
to be just plain wrong:
PING clotho.inria.fr (128.92.52.7): 56 data bytes
64 bytes from 0.0.0.0: Echo Request
RR: 0.0.0.0
clotho.inria.fr (128.92.52.7)
[...10 second pause...]
--- clotho.inria.fr ping statistics ---
1 packets transmitted, 0 packets received, 110% packet loss
I suspect the 0.0.0.0 is what's causing the problem.
If I insert the card (without any real net connection) and "ifconfig
eth0" properly then the ping works perfectly, and continues to do so
even after removing the net route to 128.93.0.0 through eth0 and
adding the static route through "lo". (!)
This is driving me crazy. Can anyone help?

Subject: dhcpcd fails to lease IP address
Date: Fri, 12 Mar 1999 15:42:12 -0500
Hi,
I have a dual booting PII 333 MHz/128 MB machine running Windows NT
Workstation 4.0/Redhat 5.1. When booted up as an NT machine my Windows NT
machine is able to lease an IP address from the DHCP server. I have also
configured Linux to use DHCP on boot to lease an IP address. But when booted
as Linux DHCP reports as error that it has failed on eth0 and coninues to
load without an IP address.
My network card is 3C905B-TX, a 3Com card.
Appreciate if anybody would tell me why this is happening. I have been stuck
for a few days not able to access the network or try anything on Linux.

Check that you have IP Forwarding enabled.
This will have to be compiled into the kernel (if you haven't already done
so) and that it is enabled.
In SuSE to enable/disable
echo 1 > /proc/sys/net/ipv4/ip_forward to switch on
echo 0 > proc/sys/net/ipv4/ip_forward to switch off
(Note may not be exact syntax, doing from memory).
Note have you created the files
/etc/ppp/options.ttyS0
/etc/ppp/options.ttyS1 and so on
ttyS0 relates to COM1, ttyS1 relates to COM2
these should contain the following the following <linux_box_ip_address> :
<dial_up_ip_address>
e.g 192.168.0.50:192.168.0.100
or linuxbox:192.169.0.100 if you have linuxbox defined in
/etc/hosts
Note, for this also to work they must be on the subnet (I think, correct me
if wrong), so the first three numbers of the IP addresses should be the same
in the above files.
Finally you may want to add +pap -chap to your configuration file, and
create a /etc/ppp/pap-secrets file.
This will enable you to enable/disable accounts irrespective of you Linux
box logins.
Hope this info helps, as I spent a good solid three weeks on our Linux PPP
server to getting it working perfectly.

Perhaps you are the first ever to try that; put that ext2 driver in w98,
