OpenWRT on RB2011UAS-2HnD

RouterOS General
1

Hi,

I’m fairly new to Mikrotik and I’ve been trying to burn the Openwrt firmware on my RB2011UAS-2HnD router.

I don’t have a serial cable (yet) so I’ve been trying to use ether boot to burn the firmware.

I’m using a virtual machine with Ubuntu on it, it has a bridged connection with my host machine.

Ubuntu is running dnsmasq with a DHCP and TFTP server, I’ve followed the dnsmasq configuration from this tutorial:

http://wiki.openwrt.org/toh/mikrotik/rb433

When I hold down the RESET button after ~20 seconds the LCD screen says “ether boot”, and then randomly restarts and goes into normal mode without loading the ramdisk, I have no clue why it does this.

After it restarts normally, the LCD shows it has successfully been assigned the IP address 192.168.6.101, which is correct according to the manual.
(At this point I am able to PING the router, but can’t telnet it?)

Which leaves me to think my DHCP server is working, but my TFTP server isn’t.

I also keep getting this message in my /var/log/syslog

Been stuck for a while now, I would appreciate it if anyone here could help me.

Thank you

Turns out I set the wrong MAC address in the dhcp-host option.

Now getting the following error:

Nov 14 17:51:17 ubuntu dnsmasq-tftp[4291]: cannot access /tftpboot/openwrt.elf: Permission denied

After a while, I managed to get the following message:

Nov 14 18:36:51 ubuntu dnsmasq-tftp[4849]: sent /tftpboot/openwrt.elf to 192.168.6.101

I should now be able to telnet 192.168.6.101, however, I get this:

thom@ubuntu:~/Desktop$ ping 192.168.6.101

Any ideas?
