Date: Wed, 04 Aug 1999 04:09:34 GMT

OK,

I installed via the local cdrom on my laptop but now I want to
confiugure networking.

I have a 3Com 3CCE589ET PCOMCIA ethernet card.  My prblem is that I do
not know what "device" to choose in order to in voke said device.

I've been through @Home access on my desktop but there it was simple -
eth0

Now I cannot figure it out.

I chose the "everything" choice during install.

Any suggestions?

Devin

You did not mention if you have a registered domain in your post. If you
don't, then there is no way for your system to receive email from the
internet. If you do have a registered domain, do you have the corresponding
MX (mail exchanger) record(s) that points towards your sendmail servers Ip
address your trying to setup?

If you don't have a regeistered domain, the only way I know of to receive
email is to address email as follows:

pcmiller@[xxx.xxx.xxx.xxx]     replace with the external IP address of your
sendmail server

Subject: Configuring Mail with an @Home connection
Date: Wed, 04 Aug 1999 03:45:54 GMT

When configuring a mail server for Linux, do I just configure
Sendmail?  Does this program both send and receive email?  What does
Fetchmail do?

If I want to receive email from the outside world, do I need a static
IP and a name registered with InterNIC?  In the meantime, can my
server just collect the mail from the @Home mail server, or does my
mail program have to collect it directly from @home?

Will QMail do all of this?

At this stage in my Linux learning, I am just trying to figure out how
to send email out from my server to the world, but I would like to
figure out how to receive email via my server.

thanks for any help or direction!

ipchains.  I have loaded the IRC module but I can not DCC anyone from my
windows 95 box which is behind the firewall.  I have enabled:

/sbin/ipchains -A forward -i eth0 -j MASQ

I have loaded the ip_masq_irc.o module.

Still no efect.

Subject: PPPD registering question
Date: Tue, 3 Aug 1999 22:03:04 -0700

I have been using pppd ( using ppp-on script) for years.
I just went to Caldera 2.2 and am having a problem.

I can get connected thru ppp0-- no sweat.

Last night, my line went down.  Now I have an automated
script that restarts my pppd.  Well, the connection would
come up.  Heres is what was in the log:


Okay, the line goes down.  So, ppp-on runs again.  The
messaages show this went but there isan entry that says
ppp1 is registered.  When this script fails, ppp-on runs
again and the log shows line registered on ppp2....etc.
While this is all happening, "netsta" shows that ppp0 is
active.  Needless to say, no connection.

What are these additional pppx lines and how do I force
my ppp initialization to use ppp0  ( Im using /dev/ttyS1 for
a device)?

A common cause of this is using a editor that uses CRLF (DOS style)
line endings rather than plain LF (Unix style) ones.

Have you tried -n on tcpdump?  10 _minuites_ sounds a bit long for a
DNS llokup to be to blame but it's worth a shot.

I'm not familiar with RH.

You can create an IP alais device and route outbound packets for
certain addresses through that.

This used to work even destinations not on the same LAN.

In a later kernel version the routing changed so that you could not
specify both a device and a gateway for the same routing table entry.

This measn this trick is limited to destinations on the same LAN.

You can work-round this limitation by giving your default router an
alias and arranging that packets to one of the addresses use one
virtual interface and those to another use the other.

There's probably another solution using NAT.

The normal solution for ICQ is to recompile the kernel with the ICQ
masquerading module included.  That allows ICQ to work on all of the
clients behind the firewall, and not just on clients mapped through
port-forwarding.

It would be more helpful for you to show us the state _after_ you
corrected the netmask.  Obviously with the netmask set too narrow you
are going to get this error.

Subject: My server won't wake up!
Date: Wed, 04 Aug 1999 01:24:39 -0500

Okay... my RH6 server runs fine if it's connected to remotely at least
once an hour or so, however if it becomes idle for more than an hour or
two it goes into this bizarre mode where it will not wake up when it is
asked for something (be it a ping, ftp, http, mail, or telnet.)  It's not
just how long I am waiting... netscape will time out, so will ftp and
telnet, and if I try again it still won't respond.

If I wait long enough (like 4 hours) it will suddenly wake up and be
fine... another way I can wake it up is log onto the local terminal and
THEN use netscape, ftp, or telenet, and the server wakes up everyone can
connect and everything is spiffy-keen.

The server is using a fixed IP so it's not a DHCP problem as some peoble
have told me.  This problem has been going on for quite a while now (like
4 weeks) and has lasted through several fresh installs of RH6.

If anyone can give any insight into what might be the problem, PLEASE let
me know!

Thanks!

HOORAY!

I am writing this to you in Netscape Messenger from Linux. I can't tell you
how fantastic this feels.

It seems that the confusion stemmed from the fact that I had many things go
wrong at once. It is tough to get DHCP working when the OS can't even see
your card. I made many changes to the configuration and abandoned those
changes when they didn't work. Of course, my ethernet card wasn't up then.
It is now.

Many thanks to Jason Brossa for his (as it ultimately turned out!) helpful
primer on setting up Red Hat 6.0 with @home. The changes to the ifup script
were what ultimately solved my problem. Down with pump!

So -- in order now: get card working FIRST, then configure IP. If you don't
notice that your card is not working until after you have attempted a bunch
of IP configuration, remember to repeat those steps AFTER the card works.

Seems obvious, but in the heat of combat things can get mighty confusing
mighty quickly.

Thanks for all your help!

In addition to the -n option, also specify the -l option if you want to
see the data in real time.  This sets up stdout in line-buffered modem
instead of fully-buffered mode.

I think you misunderstood what ethertap does.  Ethertap devices do not
provide a means to write raw packets out to a physical LAN.

Ethertap devices provide a means for userspace programs to write raw
packets _to_the_kernel_ so that the kernel will behave as though they
were incomming packets.

Anyhow SuSE 6.1 has a 2.2 series kernel doesn't it?

I that case your startup shutdown scripts should not be explicitly
adding/removing inferface routes with "route" - they are automagically
handled by "ifconfig".

Probably got 127.0.0.1 in /etc/route.conf.

Hello,

Is anyone out there running a 2.0.x kernel? (preferrably 2.0.34
Slackware release)

If so, can you tell me how to use syn_cookies? I already recompiled the
kernel with syn_cookies support, but it doesn't show up in
/proc/sys/net/ipv4

Anyone know why?
Colin
