I'm trying to troubleshoot tftpd(8).
% grep boot /etc/inetd.conf
tftp dgram udp wait root /usr/libexec/tftpd tftpd -dd -l -s /tftpboot
tftp dgram udp wait root /usr/libexec/tftpd tftpd -dd -l -s /tftpboot
bootps dgram udp wait root /usr/libexec/bootpd bootpd -d4 -t0 /etc/bootptab
%
I'm trying to boot another node via bootp/tftp.
I'm monitoring what's going on with tcpdump -vv.
bootpd starts fine, and seems to read /etc/bootptab
correctly.
But after that nothing happens, and after a few minutes
I get on the console of the host which I want to boot:
> bootp()/bsd.rd.IP32
Unable to execute bootp()/bsd.rd.IP32: invalid argument
>
Does this tcpdump fragment help to understand where
the problem is:
192.168.232.10.15388 > buzi.tftp: [no cksum] 25 RRQ "/bsd.rd.IP32" octet (
o
23:25:21.024160 IP (tos 0x0, ttl 64, id 56, offset 0, flags [none], proto UDP (1
7), length 30, bad cksum 0 (->293a)!)
buzi.19330 > 192.168.232.10.15388: [udp sum ok] UDP, length 2
23:25:51.013759 IP (tos 0x0, ttl 255, id 256, offset 0, flags [none], proto UDP
(17), length 53)
I'm happy to provide more detailed information
on the settings I use and a longer tcpdump output,
if this helps.
Many thanks
Anton
