Good day Sritej,
In regards to your PXE-booting challenge, I have a few thoughts:
- I don't see a problem with using just "pxelinux.0" in your
dhcpd.conf
file; it's probably the right thing to do
- I wonder if you actually manage to download PXELINUX and see it report
anything. I'm not clear on if you were saying that your challenge
disappears if you use the DHCP filename response "pxelinux.0"
- Tools like tcpdump and Wireshark can help to see exactly what's
happening on the network, and may be revealing
- /tftpboot/ filesystem permissions might be worth checking
- Manually using a TFTP client (Linux/BSD/Windows/DOS) and attempting to
download from your TFTP service can be a good test for TFTP
functionality
I hope some of these thoughts help you out!

Subject: [syslinux] PXEboot trouble with Soekris 4826
Hello Everyone,
I am having trouble with booting a soekris 4826 board.after setting up
my
tftp,dhcp and web servers ,I log into the board using minicom and type
boot
f0,which doesn't quite work out.
> boot f0

CLIENT MAC ADDR: 00 00 24 C8 C9 60
CLIENT IP: 192.168.200.3 MASK: 255.255.255.0 DHCP IP: 192.168.200.1
It just stops at this point,doesnt freeze.My dhcp is configured
correctly I
guess but I suspect my tftp is not ,because when I mention an incorrect
file
name in the dhcpd.conf file,it immediately reports file not found.There
must
be a problem with the file transfer.
My dhcp file is like this
/etc/dhcpd.conf
ddns-update-style none;
# option subnet-mask 255.255.255.0;
default-lease-time 600;
max-lease-time 600;
subnet 192.168.200.0 netmask 255.255.255.0 {
range 192.168.200.2 192.168.200.3;
# option broadcast-address 10.2.1.31;
# option routers 10.2.1.1;
allow booting;
allow bootp;
next-server 192.168.200.1;
#filename "/tftpboot/pxelinux.0"; when this statement is used,file not
found
is reported
filename "pxelinux.0";
}
I installed tftp server using tft-hpa-0.46 package.Then i made changes
to
xinetd.conf file :
defaults
{
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}
includedir /etc/xinetd.d
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
per_source =11
cps =100 2
flags =IPv4
}
(there are also a few tftp files in the xinetd.d directory).
My /tftpboot/pxelinux.cfg has the file C0 which is like this:
(I use a USB-serial port connector)
SERIAL 0 19200
DEFAULT /vmlinuz console=ttys0,19200,n8 initrd=initrd.img
ramdisk_size=8192
root=/dev/ram0
my initrd.img is in the /tftpboot directory and the final images are in
the
/var/www directory.
I use a USB-serial port connector.
Did I miss anything?
Thank you for your time.
Sritej
