TFTP Server wait too long

[Sven Anders]

Category: Network
Item Group: Software Error
Release: 0.94
Reproducibility: Every Time

In our configuration, we want to get a configfile over TFTP, if the server is 
availible and otherwise, use a fallback mechanism.

But, if I stop the TFTP Server, the Grub waits very long (longer than 10 
Minutes) and not use the fallback entry.
Then I press Ctrl-C the Fallback entry is booted.

But this is not possible at our production Systems, because i have to order a 
Taxi to Drive to the Server ...


A workaround is to change the Values in netboot/etherboot.h:

#define TIMEOUT            (1 * TICKS_PER_SEC)
#define TFTP_TIMEOUT       (3 * TICKS_PER_SEC)
#define TFTP_REXMT              (1 * TICKS_PER_SEC)


I don't know if this is good, pehabs someone who is firm in TFTP Servers 
schould find the real reason, why we have to wait as long



Config File is:
-- snip ---
default 0

fallback 1
timeout 8

ifconfig --address=172.16.0.21 --server=172.16.0.93

title Netzwerk Config (Default)
   configfile (nd)/configfile

title Linux-2.4.21-LIDS
    kernel (hd0,0)/vmlinuz root=/dev/cciss/c0d0p5  vga=788 apm=on acpi=off 
apic lids=0 security=0
    initrd (hd0,0)/initrd

-- snap ---
