Strange tftp/bootp/netmask problem

Strange tftp/bootp/netmask problem

Post by Nathan D. La » Wed, 30 Dec 1992 05:51:21



I have a strange problem after just converting to a class B network with
a class C netmask.  The machine has one ethernet and one slip interface
and is running on a 350, with aix 3.2.[>0<3].  My netmasks are consistent
across the entire net.  Today, when trying to boot an xterminal, it
got a successful bootp response, and then tried to tftp through my
slip interface for its files!  I removed the slip interface and it
booted just fine through the regular ethernet.  I would really like
to have that slip line working, but can't if I want to have xstations
boot from it.  The only reason I know what is going on is because we
have third party xterminals that tell us what is going on.  Our lone
IBM Xstation is, I would imagine, doing the same thing, since it won't
boot when we have a slip interface running (or even configured).

I first thought it was a reverse IP host lookup problem from the
DNS from h--l.  However, I just popped in /etc/hosts, removed all dns
stuff, and the problem still appeared.

Any ideas?  Thanks in advance.

1. Q: kernel tftp strange problem.

Hello,

I'm trying to instzll linux on a Sparc Architecture (IPX SUN4C)

I've set up a tftp server.

But when I "boot net", the kernel start loading, but never finish...
When I snoop the loading, I can see that the kernel is completely sent
by the server, but the client still want more data.
What's wrong???
I've tryed thos kernels:

vmlinux-2.0-961222
vmlinux-2.1-961210
vmlinuxSMP-2.1-961210

downloaded by the web or by ftp (in binary mode of course)

those kernels are of course uncompressed.

The snoop trace is:

The last block is sent, but the client want's more???
What's wrong?
Can it be a problem of prom config?
NOTE: Solaris boots well with boot net.....

Is there an FAQ about this?
Is it a but from SUN Solaris 2.4 in.tftpd?

Please help, I hate Solaris, and I want to turn all my IPX/SS1 into
linux boxes!

Thanks in advance.
