actually the command the HOWTO suggests is 'pppd -d -detach /dev/ttyS2 38400 &'
which i've tried numerous times and the modem always hangs up after a few
seconds.
i tried to check the /var/log/ppp.log file that you mentioned, but it doesn't
exist on my system. is there anywhere else the file could be located? if not,
does the nonexistence of the file indicate anything?

If it must not cache anything you do not need a local nameserver at all,
else see ...

Hello
I want to access the modem on box A (/dev/modem) from box B
(A:/dev/modem ?). I should then be able to setup kppp on several
machines on the LAN using one single modem (one after the other, of
course). This is for training only. I know, masquerading was the right
way.
Any suggestions?
Thanks

The idea is to point the program to an alternate sendmail program

And have /path/to/your/headers contain the headers you want.
With Berkeley mail, you'd "set sendmail=/path/to/above/script" in
the .mailrc.
With elm, you could use ~/.elm/elmheaders, swapping in your own

Date: Sun, 04 Apr 1999 19:45:26 GMT
I use Redhat.. my freind uses FreeBSD.
I installed qpopper-2.53 on my machine... no problem.
I just added all the local IP addresses to my /etc/maildb/ip_allow file.
When I installed on her FreeBSD machine everything worked great..
tested it:
bash-2.02$ telnet mymotherwearsarmybootswhenshekicksmybutt.net 110
Trying 666.999.111.222...
Connected to mymoth...mybutt.net.
Escape character is '^]'.
+OK QPOP (version 2.53) at thinker.mymot...ksmybutt.net starting.
But when I try and do the same thing from a machine that's not the server.
bash-2.02$ telnet mymotherwearsarmybootswhenshekicksmybutt.net 110
Trying 666.999.111.222...
And it just sits there.
I searched alot of newsgroups etc looking for answers but came up short. If
you may know what is wrong I am open for suggestions.
Thanks,

Content-Type: text/plain; charset=iso-8859-1

Hi there,
I�ve discovered an in my eyes strange phenomenon with my linux
IP-masquerading box and a linux workstation in my internal network. My
home net work can be described as follows :
(1) internet (2) 192.168.xx (3) 172.16.xx.xx
__________ _____________ _________
4| | 5 7| |8
|=========| |= == =====|
| | | |
| 6 | | 9 |
|=========| |=========|
1,2 and 3 are three separated ethernet segments.
6 is a linux masquerading firewall machine that masquerades all traffic
with source addresses 192.168.xx.xx and 172.16.xx.xx addresses to the
internet.
9 is a linux box that is set up as a router to route between the
192.168.xx.xx network and the 172.16.xx.xx network.
The strange thing is that when I run tcpdump on interface 4 (the
internet segment) of my masquerading linux box I see a lot of arp
requests from linux box 9 for 172.16.xx.xx addresses. It was my
understanding that arp requests should only be visible on the ethernet
segment where the network card is connected in (in my case segment 3).
Has anybody got an explanation for this?
Thanx in advance
Erik

I also love Mandrake 5.3. I have installed several diferent Linux distributions
and Mandrake takes the ease of a Red Hat install and ads KDE. I would highly
recomend it.

Actually no. This was true when most ISPs used login authentication, but
is not true today when many use PAP/CHAP -- eg AutoPPP under mgetty.
The minicom login will in fact lead you astray. Many isps will present a
login screen but when you try to use it is does nothing. It is of use
only for the sysadmins, not plebs like you or me. We are to use PAP/CHAP
right after the CONNECT message.

I agree. Slackware 3.1 could be installed with just 2MB RAM, so 4MB
should suffice.
You might try also tomsrtbt-1.7.0, a highly customizable 2.0.36 kernel
based "one floppy disk" Linux. It usually needs 8 MB RAM, but it can run
also with 4 MB (read the tomsrtbt.FAQ file).
http://www.toms.net/rb/
ftp://sunsite.unc.edu/pub/Linux/system/recovery/
Since instructions about running tomsrtbt with 4MB RAM are removed from
the tomsrtbt.FAQ file on newer versions (like tomsrtbt-1.7.118), 4MB
might not suffice for these versions. Maybe tomsrtbt-1.7.0 is still
available at some ftp servers:
http://ftpsearch.ntnu.no/
PS.: tomsrtbt is great for system recovery and many other things, but I
didn't test its performance as router.

But better and simpler than this is to get a 10$/year e-mail domain at
http://www.ddns.org (Domain mail forwarding service
http://www.ddns.org/DMF/ ). Messages sent to this domain will be
forwarded to your ISP account. Then execute fetchmail in multi-drop mode
to distribute messages automaticaly. I'm using this with success.

Uh, no. You are mixing both login authentication and pap/chap
authentication. Usually (although not always) it is one or the other,
not both. Also, no " at the beginning of the line

STrange-- I thought I had that problem, but it went away.
Try using
killall pppd
to close down the connection. The script ppp-off does not work, because
it reads the file
/var/run/ppp0.pid
to discover what the PID is of the pppd program. It then runs kill PID.
However on the later versions of the distributions, /var/run/ppp0.pid is
readable ONLy by root, so the script fails. However killall pppd
accomplishes exactly the same thing. It should work for the user who
started pppd. Youcan also write an suid wrapper for that command if it
does not work for you.
Read
http://axion.physics.ubc.ca/ppp-kill-wrapper.html
for how to do that.

Well, if it works.... However as I say, simpler methods also work.

If the pp0 was a typo for ppp0, then this looks OK
Can you pine 212.254.10.14?
What is your own IP address?
Can you ping IP addresses (not names but addresses-- eg
137.82.43.58)
If so, you have name resolver problems (/etc/resolv.conf-- make sure it
has the right nameserver lines and is readable by all.)
