Re: rpcbind vs portmap:
It's actually just whatever is in the /etc/rpc service list
as the name for progam "100000". Older /etc/rpc files called
it "portmap", and the newer ones call it "rpcbind" with
an alias of "portmap". So the output of rpcinfo -p just
depends on which /etc/rpc service list file you have.
Sorry this doesn't help you. There have been other reports like
yours: nfsd/mountd won't register with portmap (aka rpcbind).
Have you tried running portmap with a debug option and watching
when mountd or nfsd tries to register?

If you are trying to connect to AOL then I believe you are wasting
your time. If not then something is amiss with your login procedure -
which is very strange looking. To send a login name after connecting by
having chat expect a `~' is extraordinary, in fact it just isn't sensible.
If you're doing login/password then you would expect prompts. If you're
doing PAP or CHAP authentication then expecting the `~' is at least
understandable and you are likely to never need to do login/password.

You can configure the default gateway for all the LAN boxen to point to
the gateway box. The gateway kernel needs IP forwarding compiled into
it and turned on with "echo -n 1 > /proc/sys/net/ipv4/ip_forward" . You
need specific network routes on each box for the LAN that the box is
attached to. I *think* that's all that is needed provided that these
two LANs are the only ones that you have.

Subject: Why does pptp say Call Manager is already running
Date: Fri, 14 May 1999 00:37:33 GMT
Howdy, all
I am trying to set up pptp from my linux box (directly on the net) to a
pptp server. It is giving me grief.
The names, passwords, and numbers below have been changed, but they are
consistent
The pptp server is internally known as PPS, but has no external dns name
The domain is INTDOM
The ip of the server is 123.456.789.123
My user name over there is scottremote
My password is scottpass
I am running ppp 2.3.7-2, and pptp-linux-1.02. I will also want to do
the masq thing, but not until I have it working from this side.
When I say
./pptp 123.456.789.123 debug name INTDOM\\scottremote remotename PPS
kdebug 7 noauth
I get the response
warn[open_unixsock:pptp_callmgr.c:308]: Call manager for
123.456.789.123 is already running.
fatal[callmgr_main:pptp_callmgr.c:124]: Could not open unix socket for
123.456.789.123
Call manager exited with error 256
Now, this machine is on the net via a cable modem, and so already has a
route to the outside. My understanding is that after pptp connects
with ppp, I add a new route. Before I can do that, though, I need it
to connect and the ppp interface to come up. The machine does not use
ppp in any other way.
I do not want this to kill my other routes, since this machine does
firewall for other machines.
What am I doing wrong?

Subject: Messages on console with smbprint...
Date: Thu, 13 May 1999 22:44:18 GMT
Hi!
I'm new in the world of samba. But, I have succeed to configurate samba
for printing in both ways, Win95 <--> Linux.
But, when a user print, from Linux to Win95, with samba, I have a lot of
messages at console, and I don't want to have it at all.
My samba printer is configured in my printcap file, with the script
"smbprint" that I have found in the samba package.
The messages are displayed on the console when the instruction "eval",
contained in the smbprint script is executed. I have tried to redirect the
ouput of the instruction to "/dev/null" with no success.
Than you very much for your help!

Check your /var/log/message file if you see two or so lines from PPP to
the effect "Default device already defined. Default device NOT reset."
Then if you are running RedHat 5.0 - 6.0 and don't need a 'default
route' when not connected by ppp. This is almost always true for any
outging ppp using system.
edit /etc/sysconfig/network
and change the line
GATEWAYDEV=eth0 { or whatever }
to
GATEWAYDEV=''
Now when you next reboot and/or restart networking It won't define a
default device anymore. So when you start ppp0 it will automaticly set
the default device correctly.
Note: I don't use Xisp but almost all *nix ppp-service-driver work
generally the same concerning the 'default device'.
If the default device is already defined at startup then pppd won't
reset it.

Well if you have read those and still cannot get it to work, you do know
how to debug the connection and tell people on the newsgroup exactly
what went wrong-- eg include your log files so that they can see what
you are doing.
If you have not read them, then you should. It is inefficient in the
extreme for people to keep rewriting the same thing in the newsgroup tht
they have already written in those files. (and there are about 20 pleas
for help on the newsgroup every day asking how to hook up to ppp.)
So, what is your trouble in detail (ie include the output on
/var/log/messages (or /var/log/ppp if you follow the axion.physics
page)) Also include your pppd script and chat script (making sure that
you remove your passwords)
And occasionally it really is the ISP's fault.

One of half a dozen ways. You do not say what distribution you use. But all of them
have security holes that you HAVE to correct. Eg, for redhat, go to
www.redhat.com -> Support -> Product updates
and download ALL of the updates.
Actually first erase and reinstall your whole system. Then get those updates and
install
them. Then go into /etc/inetd.conf and put a # in from of every service you do not use
(especially rexecd) Eg the pop, imap, etc daemons.
Then look inot the /etc/rc.d/rc?.d files and shutdown all the daemons you do not need.
(cange the S to K at the beginning of the links.)
Eg, do not run sendmail if you are not a mail receiver. Do not run samba if you are
not
a samba server, etc.

Look in <kernel-source>/Documentation/sound . But I think you have to
recompile your kernel. Everybody could have another soundcard. So you
have to build your card (=soundblaster) as modul in the kernel manually.
In a xterm type "cd <kernel-source> " and then "make xconfig". It�s quit
easy. <kernel-source> is by default /usr/src/linux . With your network
card it�s the same.

Too bad guy's it was all for nothing.
Sylvan has tagged us all as idiots if we
don't get their Linux certification.
I feared it would be the demise of the Os
and now it is so. I guess we leared to
hold the rights to certification the next
time we build an Os. Nce work to all who
participated. But now with all the cheeters
entering the Linux field it will be sure
to be just another Microsoft and novell
"reboot it!" server with a bad track record.
Next time the next Linus will have to protect the
Os's trademark against these
Os killers certification processes.
I am sorry to say I have decided to start
work on another OS (open source of course)
with protection from the Sylvan Empire
(dark side).
Since Sylvan now has the say as to who can
be employed using linux and only if you use
Linux they way they say you should. Or in
short they now own it!
I have decided to start planning another os
but hold the rights as to whether or not anyone
can
"CERTIFY" people in the OS.
Making it fair for all to compete illiminating
the
Political B.S. of Sylvan
Which Linux has now fallen victim too.
Best of luck to Linux anyway. It was hard
work and truly is a great os but I can't
say I did'nt see it comming either. It almost
made
a great Os.
If any one has any ideas on how this protection
can
be implemented on an
already open source product. Maybe we should try
to
save it. Have a talk with Linus or something.
