Hello All,
I am having a bear of a time with NIS. Has anyone be able to get Linux
NIS
to work with HP-UX 10.20 or Solaris 2.6? I've tried RedHat 5.2 (2.0
kernel) and Redhat 6.0
(2.2 kernel). I am trying to have large Linux box be the NIS server.
Other Linux boxes can bind
and read user info just fine. However, Solaris can bind, but can't read
user passwords. I am not
using shadow passwords on the Linux NIS server. The HP-UX box can't even
bind to the RH 6.0
box, but can bind to RH 5.2.
Has anyone got this to work? I've seen lots of questions about this
on the net, but not many answers. It seems that a bunch of people are
trying to do something
very similar (Linux as the NIS server), but are having problems with it.
Any help would be great! Please!!
I will post the solution.
Thanx
Rayman

I want to use ipfwadm to make what I've been told Cisco calls
a "Static Translation" for a firewall. I want to forward all
traffic destined for one IP address (on eth0) to another ip
address (which is routed through eth1).
Does anyone know how to do this?
Please respond via email as I don't read newsgroups often.

Subject: Wyse 185: broken keyboard?
Date: Mon, 26 Jul 1999 19:31:12 -0400
I recently aquired an aging Wyse 185 terminal from a friend, and since I
couldn't find a DB9/F -> DB25/F null modem cable, I got a F/M and used a
serial gender changer on the DB25 end. I added an entry in /etc/inittab, but
upon boot, all I get is a beep and a momentary screen flash from the
terminal. Then it displays its usual, un-connected screen.
I can do a "cat > /dev/ttyS1" and get output on the terminal, but cannot
read anything *from* COM2.
My question is this: could this problem be caused by the use of this gender
changer, or is the keyboard broken...or something else? The same things
happen when the terminal is connected to an OpenBSD and a FreeBSD box.
Thanks!

Dear,
I have installed Red Hat 6.0 without any problem. But when I make an new
compilation of the kernel (i.e. for adding NFS support) in the good way
(make dep; make clean; make zImage) (cp
/usr/src/linux/arch/i386/boot/zImage /boot/vmlinuz-2.2.5-15)) (/sbin/lilo)
after rebooting the new compiled kernel the following message appears:
NO SETUP SIGNATURE FOUND....
I have never had this problem with the versions RedHat 5. 0 and Red Hat
5.2.
So, now with the version Red Hat 6.0 I have this problem.
Please help me. Thank you very much

Been there, done that. I had the smart of idea of using a 486 with 8MB
of RAM for a firewall and recompiled the kernel on the machine. I
ending up coming back the next morning to finish the job.

Hi,
my company just installed a leased line.
However, i don't know how to set it up with my Linux box?!
I want to set up a mail server with proxy.
How can i do that?
1) sendmail + proxy or
2) sendmail + proxy + procmail or
3) sendmail + proxy + procmail + dns or
4) anything else?
Any idea is welcome!
Thanks,

I have a Jornada 680 with Windows CE on it. I also have a machine with
Debian 2.1 installed on it. The two are connected through a serial cable
on /dev/ttyS1.

Ok I'm nearly ready to kick the sh** out of this damned computer
Running RH 5.2, with a 2.0.37 kernel.
I have a local network, and want to allow it access to the 'outside
world' via a machine on the network with a ppp connection over modem
I have the rules currently configured so:
ipfwadm -F -f
ipfwadm -I -f
ipfwadm -O -f
ipfwadm -F -p masquerade
ipfwadm -I -p accept
ipfwadm -O -p accept
in order to eliminate any possible bad rules blocking any traffic. (I
realise this is amazingly insecure, it's only this way for initial
testing..)
Kernel has allll firewall options configured, including packet defrag.
Other machines on the local network, when the ppp link is up, can
STILL **not even ping** outside the local network, let alone do DNS, I
have been unable to try anything else.. and they ARE configured to use
the ISP's DNS.
I don't get it, what have I missed??
Help MUCH appreciated at this point, before my hair starts to suffer!

Your ethernet card was not initialized properly. Here are some reasons why
this
may have happened, and the solutions:
1. Your kernel does not contain support for your card. Including all the
network drivers in a Linux kernel can make it too large to even boot,
and sometimes including extra drivers can cause system hangs. To
support your ethernet, either edit /etc/rc.d/rc.modules to load the
support at boottime, or compile and install a kernel that contains
support.
2. You don't have an ethernet card, in which case you should comment out
this section of /etc/rc.d/rc.inet1. (Unless you don't mind seeing this
error...)
END

You still have to set up routing. Find a routing howto. If you have routing
set up, make sure that the other machines are pointing to the firewall machine
as the default router.

If you are starting sendmail when your Linux machine starts, it may
be the culprit. Take a look at what processes are running and see if
anyone of those may be causing a problem.
