Possible solutions:
--You mentioned that you get tons of "crap" in minicom? You know that's
probably the PPP stuff you want to see, with lots of {} signs and stuff
like that.
--When you start pppd, do you use hardware handshaking and set the modem
as the default route so that all IP packets that go from your browser go
to the ppp link and not through any NICs you might have? You should be
able to do this manually: open minicom and dial your isp and do whatever
you have to do to get PPP "crap" showing up (ask your ISP...there are
many different ways PPP servers do this). Then do an Alt-Q, and try to
start pppd with the command:
pppd /dev/modem crtscts defautroute
the crtscts does hardware handshaking which is pretty essential, and the
last command makes sure your IP pakets that are not intended for anyone
on your LAN go to the ISP through your modem. You can also check your
routing table, and should have an entry that shows your ISP as the
gateway, "default" as the destination, 0.0.0.0 as the Genmask (0.0.0.0
is the IP address for "everywhere else"), and ppp0 for the Iface
(Network Interface).
Hope this helps.

Edit the file /etc/sysconfig/network. Set the forwarding line from no to yes
and restart.

My local ISP is horrible and I am looking for a new ISP. The
connection speed to Microsoft Network from my local place is good.
Here is the question: Is MSN ppp dialup a good choice for linux
technically? Does MSN use standard PPP protocols ?

Every place I've worked at, there has been a machine called Merlin. The
first place used bird names and a VAXcluster called AVIARY. The second
place had different naming schemes for different departments, and Merlin
belonged to another project - our system manager was heavily into
Shakespeare, so nodes were named after characters from his plays -
Oberon, Banquo, Pistol, Scroop and so on. The third place ended up with
Arthur, Merlin, Galahad, Lancelot and Mordred, a border router called
Moat and two ISDN routers called Sword & Stone. My current post has
followed a similar scheme with servers, but with other Welsh characters
- Glyndwr and Madog.

This job is a 'bear' so I call my NT Domain KODIAK. Then I use KOALA, PANDA,
TEDDY, POLAR, etc.
Until this Pathworks/NT thing gets better I think these are justified.

Subject: Re: Firewall blocks squid
Kai,
I had to enable traffic over the loopback interface (127.0.0.1), then
squid started to work for me.
I only permitted incoming traffic on port 3128 (squid proxy port) for
the interface to the internal network, no other ports required there. I
don't
now where your connection requests for the other port come from.
BTW, have you configured your firewall by hand, or did you use any
supplied scripts like within SuSE? You didn't mention which of these
protocols are enabled on which port... the rules can be more complex
than what you quoted.
Regards,
Jens

As far as I know your telnet is working fine. Is your http and www set to
the correct port in /etc/services ?
This is what I would do :
telnet toad.stack.nl 80
Type something and wait for the response. If it is in HTML it works. If it
isn't your server might use another port for HTML.
It's not a very profesional way but it worked for me.

Subject: testparm hangs
Date: 23 Feb 1999 22:00:55 GMT
hello all. i've been playing with my smb.conf and resolv.conf files to
connect my linux server (RH 5.2, kernel 2.0.36-0.7, samba1.9.18p10) to my
windows network. at first, running testparm kept giving me the following:
Get_hostbyname: Unknown host WHL31
Failed to get my host name.
so, then i added the following entry to /etc/resolv.conf:

now, when i run testparm, it hangs with no messages displayed. i can use
CTRL-C to cancel the command.
what's am i missing here? i've added more background information below.
thank you in your attention in this inquiry. any suggestions would be very
welcome. if you'd like to respond directly to my email address, remember to

I would look into a PPP connection. Linux will have no problems
working over a null-modem connection; not sure how you'd convince
Windows to do the same, but I'm sure there's a way. Don't have
a box handy to muck with right now, but... (Probably want to
look into hacking together a "null modem" pseudo-modem INF file,
if you don't already have one; the 'ROLM DATAPHONE' INF file
would probably be easily adapted.)

Subject: IP Forwarding with Suse 5.2 and Startup Scripts
Date: Tue, 23 Feb 1999 22:45:25 -0000
How can I enable IP Forwarding at startup on Suse 5.2.
I know that if you do the following
echo 1 > /proc/net/sys/ipv4/ip_forward
this enables IP fowarding.
Is there anyway to automate this at startup because by default it is
currently switched off.
Also how do run programs and scripts upon booting the machine. Do you put
the entries in /etc/inittab.
By the way, I couldn't remember the correct sysntax of the above command, so
the
above syntax may be correct.
