Well, I think you got the solution there. I believe Joe stumbled

Sorry, I couldn't resist a challenge...this could be fun. How many
different ways
can you do this?
If you can use ksh...here goes (note the colons!)
#!/bin/ksh

If you can get this guys IP he may be easier to catch than you would think. A
lot of serious ISPs are starting to implement a new version of Cisco Secure
Access Server that logs usernames as they acquire an ip address when dialing

Subject: autofs using smbmount
Date: 22 Jan 1999 10:16:38 GMT
on recommendation of other usenet posters, i'm trying to setup autofs
to use smbmount to mount a few shares on a windows machine on demand.
my file structure would look like this:
/windows/c --> \\windows\c
/windows/d --> \\windows\d
/windows/cdrom --> \\windows\cdrom
could someone who has done this before please post some example
scripts and an auto.master file, or direct me towards some good
resources. i almost have it i think, but i'm not sure if i'm headed
in the right direction or not.
i'm running linux 2.2.0-pre9, samba 2.0.0, autofs 3.1.3 and windows
95. i can successfully use smbmount by hand to mount the shares on
the windows machine, so that part is not an issue.
thank you.

Subject: "New Mail"-Notification via smbclient
Date: 22 Jan 1999 08:52:27 GMT
Hi,
I am running a linux mailserver that receives mail via UUCP over TCP.
The mails are sorted into the users' mailfolders in /var/spool/mail via
procmail and are fetched from windows clients with pop3.
The problem is that some users never check if new messages arrived, so i
decided to put winpopup into the startup folder and run smbclient to
notify them.
But - you guessed it - I could not figure out how to do it.
For testing, I just piped the whole message into smbclient via
/etc/aliases:
joe.user: "|/usr/bin/smbclient -M winhost -d 3 > /tmp/debuglog"
/tmp/debuglog says, that 500 or so bytes are transmitted. Only winpopup
does not popup. This works perfectly with exactly the same debuglog
when run from the commandline (no matter under what uid) , e.g.
cat /var/spool/mail/joe.user|/usr/bin/smbclient -M winhost -d 3 > /tmp/debuglog
I also tried to run smbclient from .forward with the same result. When put
into /etc/aliases, smbclient is executed as user daemon, but this does
not seem to be the problem because su - daemon, cat cat /var/spool/mail[..]
works.
Any ideas?

I think you could try making sure that your PPP connection becomes the default
gateway when active. It sounds as if your trying to ping adresses on the
internet using the default gateway eth0.

I think I am getting closer. I found a PERSIST variable that I set to
"no" in ifcfg-ppp0.
I also added
/etc/sysconfig/network-scripts/ifup ppp0
to a once-an-hour cron job.
I think it's working. It would be nice if someone added this to the
ppp README file. I didn't see any documentation on the variables in
the ifcfg-ppp0 files.

Most of the commercial null modem adapters that I've seen implement the

Remote login as root is disabled for security reasons. You can login as a
normal user and change to root with: 'su -'.

Je root login is geblokkeerd voor remote toegang. Door het bestand
/etc/securetty (secure tty) aan te passen kun je die toegang openzetten.
Probleem alleen is dat je er moet opgeven vanaf welke (pseudo)terminal je
inlogt, echter bij een sessie via het netwerk is dat telkens iets anders.
Ik heb het opgelost door ttpy0..15 er aan toe te voegen. Dan kunnen de
eerste 16 remote inloggers als root inloggen. Dat lijkt me voldoende voor
mijn toepassingen.
Overigens (dit is een meer algemene tip), doe je beheer op een UNIX machine
als volgt:
Log in als normale user
Doe alle voorbereidingen
Wordt root (su root)
Doe de installatie
Wordt weer gewone gebruiker.
Onder NT moet je altijd eerst als Administrator inloggen en dan kun je alles
wat je moet doen. Dat maakt het veranderen van iets kleins tot een
uitgebreid klusje omdat je eerst je sessie moet afsluiten, maar onder Unix
kun je b.v. gewoon een xterm openen en root worden in dat venster.
Bas.

I may be wrong, but I believe 10BaseT and 10/100 cards need to see a "Link Beat"

won't work.
It's so easy to buy an inexpensive hub, why not just do it?
