DNS override issue
by Chris Edwards 13 Feb '23

13 Feb '23

Hi, I'm trying to use the "Fixed local DNS host entries" feature to specify a particular IP for a certain remote hostname. In this case the hostname in question happens to be a CNAME. Watching the DNS traffic with tcpdump seems to show the client (an iPhone) making two queries: (1) a regular 'A' query, for which the firebrick happily responds with my chosen override IP. So far so good, however the client also makes: (2) a 'TYPE65' query (which I think is a new thing akin to CNAME). Here the firebrick passes on the original CNAME record. Upshot is the client gets two conflicting answers, and picks one at random. I'm not sure whether this is a bug or a feature. However for this IP override facility to work, I guess the Firebrick would need to return an empty reponse for the TYPE65 query, to convince the client the hostname is just a simple A record (for the override IP). Firebrick 2700, latest code. Chris

Starlink

Do we have someone using a FireBrick on a Starlink ? Interested in helping us sort out IPv6? Let me know, so we can look at loading an alpha with some debug to confirm how they work. -- Adrian

Re: Switches disappear from the home screen

Useful, that means no “slots” for the http for the web socket. That is unusually unless there is some sort of leak. The status / process list may be useful. But likely a power cycle would fix anyway. > On 5 May 2022, at 10:52, Paul Cooper <paul(a)hwhb.uk> wrote: > > This is what it says in the web inspector: > > WebSocket connection to 'wss://firebrick.hwhb.co.uk/profile' failed: Unexpected response code: 429 > > Paul > >> On 5 May 2022, at 06:51, Adrian Kennard <a(a)k.gg> wrote: >> >>> On 04/05/2022 22:47, Paul Cooper wrote: >>> I am using FB2700 Macleod (V1.59.000 2022-04-13T11:47:50) and have a number of switches/profiles on the home screen.

Switches disappear from the home screen
by Paul Cooper 05 May '22

05 May '22

I am using FB2700 Macleod (V1.59.000 2022-04-13T11:47:50) and have a number of switches/profiles on the home screen. They momentarily appear but disappear again within.a second. I have tried various browsers and different devices and they all behave the same way. I have not rebooted the FB yet to see if that clears it.

FireBrick and DHCPv6
by Mark Lucas 29 Apr '22

29 Apr '22

After reading the FB2900 manual am I correct in thinking that the FB can only act as a DHCPv6 client and not an actual DHCPv6 server? If so are there any plans to add a DHCPv6 server to the FB or is it now considered redundant? I have a couple of devices which need it. Thanks Mark Lucas

DHCP JSON logging
by Mike Zanker 20 Apr '22

20 Apr '22

Just upgraded to 1.59.000 and I’m now getting the JSON logging for DHCP in addition to the original logging format. How can I go back to just the original format by itself? My DHCP config is <dhcp name="LAN" ip="192.168.100.8-127" dns="192.168.100.1" time="" ntp="" log="default”/> Thanks, Mike

SNMP v3
by Mike Zanker 20 Apr '22

20 Apr '22

Just wondering if there are any plans to support SNMP v3 any time soon. I’ve never had a need for it before but now need to monitor a remote network and want to ensure that community strings are not sent in the clear. The remote Zyxel switch supports it (and this will let me monitor the port that’s connected to the FB) but it would be nice to be able to query the FB ports, too...

Firebrick bonding x8
by Ben Wilkinson 23 Dec '21

23 Dec '21

Hi, The nay sayers said it could not be done, and I am not sure what the current maximum anyone has tried is, but we just deployed an 8 way FTTC bonded setup on a FB2900 and this works very well :) Might have accidentality hit the forwarding capacity for the FB2900... but upload was the top priority!

MQTT broker
by Paul Cooper 16 Nov '21

Just loving the recent MQTT broker feature. I’m only using the basic non-secure mode but it seems extremely stable. It means I don’t have to run Mosquito on a Raspberry Pi anymore. Great addition – many thanks. Paul

Firewall changes don't take effect until a reboot
by Paul Cooper 22 Oct '21

22 Oct '21

TLDR: Changes made to the firewall rules don't take effect until my FB2700 does a full reboot. I'm running a 2700 with Kaplan. I was wanting to track down which IP on my local network was generating a lot of traffic so I created a rule to graph certain IPs and then did a binary search on the source IP to identify the offending device. I didn't find it. So I widened the search criteria to the full allocated DHCP range and still nothing. I decided to reboot and suddenly the rule started working. I then tried other firewall changes such as creating a disable profile. Again, any changes I made had no effect until I rebooted the FireBrick. I then wondered whether it was a Kaplan 'bug' so I downgraded to Jacoby but the same behaviour occurred. I also tried power-cycling the Firebrick, but again the same behaviour. The next thing I want to try is a full factory reset but that will be awkward so I thought I'd first ask in this forum to see if anyone has any suggestions. Also, do the developers wish me to create any logs to send to them? Paul
