I don't think this will work. Presuming the LAN connection is an
ethernet card then changing your script to check for eth0 will always
'do something' because eth0 can present wether or not the machine is
physically connected to the network.
If you know that a particular IP address is in use on your network that
you could try something like
pppup=`ping -c 1 x.x.x.x | grep '100%'`
Where x.x.x.x is an address you know to be 'pingable' on your network.
Not an ideal solution, and it will introduce something like a 6s delay (
on this machine ) when not on the network upon running the script

It's the color depth you are running at I would believe. Try starting X

I've seen the same problem, and the MTU/MRU
limitation suggested in follow-up notes didn't do
the trick. I did some packet tracing of Ricochet
vs. modem access to a local ISP and discovered
that there were some subtle differences in the
protocol negotiation. This persuaded me to
disable Van Jacobson compression and all is well!
FYI: pppd 2.3.7 with kernel 2.2.5-15 w/ ppp 2.3.3
and kernel 2.2.9 w/ ppp 2.3.7 had the same
problems.
Since diagnosing the problem, I found Alan Cox
reported this problem for a pre-release of 2.2.0.
It looks like this problem has not been resolved.
He suggests setting the pppd option "-vj", but
you'll have to use "novj" with later versions of
pppd.

Hey Mattis,
you have sent very poor information about your
samba configuration.
Do you have a PDC running,
do you want to verify the passwords
by the PDC or by your Linux Server,
have you added your passwords with
smbpasswd, are theses passwords the same
as the passowrds created with passwd,
are you using a NIS server,
have you checked your smb.conf file
with testparm?
That's enough for the moment.

Betreff: Not getting anywhere with Samba
I can see our Linux (Debian 2.1) server in our NT/Win98/Win95 network,
but cannot access any files. I've tried various settings in
samba.conf, but would surely appreciate advice from someone who has
gotten this to work...

The problem is the alias at /etc/conf.modules, but I don't know ALL the
solution.
Following is what I have:
alias eth0 rtl8139
alias eth1 ne
options ne io=0x340 irq=5
So, there is no problem between rtl8139 and ne. If you have TWO equal
NICs,
you cannot write options for them (or I don't know how), until you name
them different. One solution (not good, but it works) is to change the
name
of the driver say for eth1: in my case they are at
/lib/modules/2.0.36-0.7/net,
so cp /lib/modules/2.0.36-0.7/net/ne.o
/lib/modules/2.0.36-0.7/net/neplus.o,
and then you can do
alias eth0 ne
alias eth1 neplus
options ne io=0x340 irq=5
options neplus io=0x300 irq=3

Try lookin' into /etc/hosts.[deny|allow] and if this is totally isolated

One thing, your /etc/passwd file could be vulnerable for password
cracking if you don't implement shadow passwords.
It's built-in in the 5.2. YOu only have to enable it but there are warnings
of course.

Subject: DUN/ppp problems with Redhat 6.0/Gnome
Date: Wed, 09 Jun 1999 11:55:33 GMT
Hi everyone,
I just installed Redhat's Linux 6.0 on my machine yesterday. The
installation went well, X works, all my peripherals work, but I
can't get dial up networking to work.
All of my hardware is ok since everything functions in windows,
and while in Linux the modem does dial out and some kind of
connection is apparently made. I suspect that something is not right
with the script I'm using with Gnome's linuxconf utility.
In Windows, I temporarily forced DUN to step through the logon
procedure. Here are the logon prompts, plus all of the remaining
text that I get:
Welcome to Sprint-ip
sdn-ar-001arfaye00lt slot:3/mod:7
User Access Verification
login:
Password:
---
Now, with Windows, after the password is entered, I get the following
text:
Welcome to Earthlink, entering PPP mode~
...and then the connection is completed.
In linuxconf I have the first expect line set to "ogin", then I send
my logon info, then the second expect to "word:", then I send my
password. I've tried at least 20 different permutations of the
script. I'm not absolutley certain that the problem is with the
script, but I can't access web pages, ping doesn't work, so I would
bet that my connection is simply timing out.
I guess it's also possible that the modem connection isn't being made
properly. Does anyone know where in Windows I can find the init
and dial strings that DUN uses?
I would greatly appreciate any suggestions as to what I should do
next.
Also, if possible please CC your response to me via e-mail, becuase
Earthlink's newserver has been acting up lately and I might not
ever see your message.
