Netinstall stuck at "Waiting for RouterBOARD..."

Sat Oct 07, 2023 7:26 pm

Been stuck trying to un-brick a CAP XL ac, and have not got netinstall to work.

Most specifically, netinstall hangs having done this:
[root@netinstall ~]# ./netinstall-cli -a 192.168.88.1 routeros-7.11.2-arm.npk 
Version: 7.12rc1(2023-10-05 06:32:41)
Interface Mask: 255.255.255.0
Using Client IP: 192.168.88.1
Using Server IP: 192.168.88.2
Starting PXE server
Waiting for RouterBOARD...

I have a dedicated virtual machine running Rocky9 that is installed for the sole purpose of netinstall.

The network is configured as follows:
[root@netinstall ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 52:54:00:d7:28:34 brd ff:ff:ff:ff:ff:ff
    inet 192.168.88.2/24 brd 192.168.88.255 scope global noprefixroute enp1s0
       valid_lft forever preferred_lft forever
    inet6 fe80::5054:ff:fed7:2834/64 scope link 
       valid_lft forever preferred_lft forever
3: enp7s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 52:54:00:6d:44:7b brd ff:ff:ff:ff:ff:ff
The CAP XL ac is connected through an RB5009. The netinstall virtual machine sees bootp traffic as below. I have confirmed that the MAC address matches the MAC address printed on the outside of the bricked device.

Looking at the netinstall process, it appears to have forked itself, one process listens on port "commplex-main", the second listens on "bootps" and "tftp":

Am I correct in understanding that seeing the bootp incoming traffic means that the CAP XL ac is in etherboot mode, and is correctly broadcasting bootp packets?

Why does netinstall hang?

There are multiple ways for firewalls to break things. In the case of Rocky9 you need to disable the firewall like this:
[root@netinstall ~]# service firewalld stop

You needn't be so heavy-handed. My Netinstall on EL9 guide shows a more enlightened path. You may find that it helps you with more than the firewalling aspect.
