Lan boot/install problem

Ryan Hurst — Tue, 18 Mar 2003 22:21:19 GMT

Ok, I have successfully made and restored a raven system (c110) using ignite. To do this, I made the net recovery using the ignite gui. To restore I did a "bo lan. install" and it worked great.
Now I am trying to do it with an allegro system in the same way. I successfully made a network recovery archive of the allegro, but the "bo lan. install" command dosn't work at all. I then did "sea lan install" and found some other system, but not my ignite server. If I do the same command on the raven system, both the other system AND my ignite server show.
The raven, the allegro, and my ignite server are ALL plugged into the same hub. The other system is somewhere else on the network.
My question is: Why can't the allegro see the ignite server, while the raven can? Also, how do I fix this?

Are the client and the ignite server on the same subnet?

If not, you need to configure a boot helper. See link below.

Hi,

looks like machine allegro is on different subnet, whereas raven and ignite server are on same subnet.
if the client is on different subnet then a boot helper needs to be setup. look at this URL:

Are you sure this hub is not a switch with different VLANs? If yes, try to change the patch cord (ignite server -- allegro).

Wilfred and Ravi:
How would I tell if the client that is in the boot console handler is on a particular subnet? I just plugged it into the switch (sorry I said hub at first, I should have made the distinction) along with the server and the working raven client. As I said before, both the working raven client and the non working allegro client can see another ignite server, but only the raven can see MY ignite server. If it helps, I'll mention that both MY ignite server and the other ignite server are on the same subnet.
Sergejs:
You're right, it is a switch, not a hub, I should have mentioned that. However, I don't belive that there are any different Vlans involved. I just powered up the switch and plugged the server and the two clients into it, as well as the lan-drop that goes to the rest of the company's network.

Thanks everybody, I eagerly await your reply!

Hi,

can you post #ifconfig lanx (x is interface number) command output of both the machines, raven and allegro

Re: Lan boot/install problem

Ryan Hurst — Wed, 19 Mar 2003 16:13:04 GMT

Output from ifconfig...

working raven client:
lan0: flags=843
inet 150.1.10.16 netmask ffff0000 broadcast 150.1.255.255

nonworking allegro client:
lan0: flags=863
inet 150.1.10.11 netmask ffff0000 broadcast 150.1.255.255

Hi,

can the ignite server can see allegro (try to push s/w from ignite server into allegro)

Re: Lan boot/install problem

Ryan Hurst — Wed, 19 Mar 2003 16:33:20 GMT

I'm not sure what exactly you're asking me to do, but if you mean can I ping and telnet etc. from the server to the client, then yes.

pretty basic I know, but just to rule out the switch. Have you tried swapping Raven & Allegro connections at the swith over.

Re: Lan boot/install problem

Ryan Hurst — Wed, 19 Mar 2003 16:52:55 GMT

It's ok, in some areas, my knowledge is pretty basic as well.
Yes, I tried swapping the connections, it made no difference.

This one looks like it would be easy but I gues it's not. The only hint I can give is from the man bootpd page and maybe this would apply to the Ignite server's configuration. So check /etc/dhcpdeny and /etc/bootptab files. Remember when you setup up and Ignite server it functions as a dhcp/bootp server as well:

When bootpd receives a DHCP/BOOTP request, it first checks if the
hardware address of the client is listed in the /etc/dhcpdeny
database. If yes, this client is denied lease. If the client is not
listed in the dhcpdeny database, it checks whether the client
information is in the /etc/bootptab database. If the client
information is available, bootpd sends back the reply. Otherwise, it
checks whether there is any matched relay information for the client
in the /etc/bootptab database. If so, bootpd goes through a series of
checks to see if it should relay the request. If no matched relay
information was found, bootpd checks whether the client information is
matched by a pool or device group in the /etc/dhcptab database. If a
match is found, bootpd sends back a reply. The request is dropped if
no matched group information is found.

One other thought, when you run Ignite from the Ignite server, does allegro show up in the list of clients? If not try adding it first.

Re: Lan boot/install problem

Ryan Hurst — Wed, 19 Mar 2003 17:17:57 GMT

Yes, I've added and made a network archive of the allegro client on my ignite server. I'm still working with the info from your previous post...

Re: Lan boot/install problem

Ryan Hurst — Wed, 19 Mar 2003 17:45:25 GMT

Ok, there aren't any dhcp related files since dhcp isn't configured on my server. The bootptab file had the following entries in it:

ignite-defaults: ht=ethernet: hn: bf=/opt/ignite/boot/nbp.efi: bs=48
System-IPF: tc=ignite-defaults: ha=00d009000000: ip=190.40.101.22: sm=255.255.248.0: gw=190.1.48.1: ds=190.1.48.11

I tried adding an entry specific to my wayward client. It didn't change anything.

strange indeed !

How far does "bo lan. install" get ?

Mike:
I guess I should clarify...
After hitting enter and answering "n" to the interact with ipl question, it tries to boot for a minute or so and times out, being unable to find a "nonexistant device".

What is the subnet for your ignite server? Is lan0 on 150.1.10.0 as well?

All subnet has to be the same and also they should all use lan0, or the primary lan.

Re: Lan boot/install problem

Ryan Hurst — Wed, 19 Mar 2003 20:20:27 GMT

Yes, all of them are on the same subnet. This network is relatively small and unsophisticated. They are all connected through thier built in NICs at lan0.
