I'm attempting to get a TFTP server working, from my workstation. I've actually attempted this multiple times, never succeeded. I've setup real tftp from a router, but my home router is nothing close to a cisco. I'm forced to do this from my workstation, and as expected unable to get dnsmasq to repsond to a dhcping

This is my plan, TFTP some firmware to my new router... To replace the very limited home router. The upload is ONLY possible from TFTP, believe me I was looking for any possible alternative. I'm unable to ZMODEM via serial, and soldering a JTAG would be even more difficult than this plan. I actually don't need the internet really working from the TFTP server interface, just want that firmware accessible.

eth0, connected to home router:

inet addr:192.168.15.109  Bcast:192.168.15.255  Mask:255.255.255.0

eth1, TFTP server, should be static? I'm sure I did this wrong...:

inet addr:192.168.15.10  Bcast:192.168.15.255  Mask:255.255.255.0

dnsmasq.conf

server=192.168.15.10
interface=eth1
dhcp-range=192.168.15.11,192.168.15.20,12h
enable-tftp
tftp-root=/var/tftp

Route

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         ZillaNet        0.0.0.0         UG    100    0        0 eth0
link-local      *               255.255.0.0     U     1000   0        0 eth0
192.168.15.0    *               255.255.255.0   U     0      0        0 eth0
192.168.15.0    *               255.255.255.0   U     0      0        0 eth1

Do I need to create some type of route? What Should I do to get this working?

  • Your configuration looks fine. Is the new router connected to eth1? Can you provide the output of ip route? Have you tried to get the router to DHCP or have you only tested with dhcping? – mgorven May 22 '12 at 7:16
  • only tested with dhcping, updating the OP with route output – J. M. Becker May 22 '12 at 9:21
  • just noticed the dhcping gave no response, even with the home router :P I'll give the firmware a shot in morning. – J. M. Becker May 22 '12 at 9:24
  • ..ya no boot, no log in /var/log either. – J. M. Becker May 22 '12 at 11:16
  • There is no way I have this networking correctly configured – J. M. Becker May 22 '12 at 11:17

OMG I finally got it working. I followed the instructions on this page!

basically I had my network config incorrect, and in addition was blocking the traffic via iptables.

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet static
address 192.168.16.1
netmask 255.255.255.0
network 192.168.16.0
broadcast 192.168.16.255

I did not need to create the manual routes, as I did not use Internet.
