Booting SGI O2 R5000 IP32 180Mhz

I'm posting as much information as I can so I can get a second opinion.

I can't boot via the command bootp(): root=/dev/ram0 On the sgi I get this output: Setting $netaddr to 10.1.2.11 (from server ) Unable to execute bootp():: Invalid argument

ashpool root # ls -l /tftproot/

try changing this:

filename "/tftproot/ip32-r5k-20050128.img";

to this:

filename "/ip32-r5k-20050128.img";

I think with tftpd if you have the tftproot directory already set in it's conf file, then you don't need to set it again- your system might be trying to find the file at /tftproot/tftproot/ip32-r5k-20050128.img if you hardcode that path in there..

Okay I tried it both ways in /etc/dhcp/dhcp.conf and got:

Mar 15 15:24:18 ashpool in.tftpd[13445]: RRQ from 10.1.2.11 filename /ip32-r5k-20050128.img

I'm still have the same problem. Any other thoughts?

thanks,

I used a cross over cable and went direct between these two machines.,

tcpdump -v
I'm guessing this is the relevant stuff.

What do you get if you type cat /proc/sys/net/ipv4/ip_{no_pmtu_disc,local_port_range}? It should be something like this:

Okay its booting thanks very much!

Redhatter · Posted: Tue Mar 22, 2005 12:38 am Post subject:

Yep... like many other files in /proc, it's set back to the default value once it boots.

If you want the change to stay, try putting the appropriate commands in /etc/conf.d/local.start

I'm in the process of trying to do the same thing as jmarcus and am getting the same error message. However, unlike jmarcus, I did NOT follow one of the instructions in the MIPS handbook, and that is the part where you funnel stuff into /proc.

Dear Redhatter,

Thank you for the advice; I'll give it a try!

I went back and re-read the handbook, but--and don't get me wrong, I think the Gentoo manuals are really well done--it still was not clear to me WHERE the funneling into /proc was supposed to be done: on the SGI or the boot server. Admittedly, now when I re-read:

Hey, thanks for the feedback... Does this look better?

iMike

Dear Redhatter,

Yes, that is clearer. Thanks for taking the time to improve the wording. Also, a big thanks for your tip. My O2 netbooted with Gentoo this morning :!:

just following the docs with your tip on where to funnel those values on the tftp server. You is da man! Thanks

/Mike

Just for clarification, the Port and MTU bits only need changing on Linux systems with a kernel 2.4 or greater. IRIX, Solaris, Linux 2.2, etc.., don't need these settings applied.
