I want to netboot a SGI Indy. It uses bootp to acquire the address and needs the bootp reply to be without the DF bit. It worked fine in Linux 2.2 and had some troubles in 2.4 (don't remember whether I got it to work or just booted to 2.2) and I cannot get it to work with 2.6. I am using 2.6.5. echo "1" > /proc/sys/net/ipv4/ip_no_pmtu_disc doesn't seem to have any influence on the generated UDP datagram, it's still DF. Is the sysctl broken or do I need to something different to send UDP datagrams with no DF bit? -- Meelis Roos (mroos@linux.ee) - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
