RB450G and “..could not get answer from dns server” – MikroTik
Posted by jpluimers on 2020/07/06
[WayBack] RB450G and “..could not get answer from dns server” – MikroTik: I do not see a default route. It would be the route with “dst-address=0.0.0.0/0“.

Research list: machine sometimes not visible on LAN
Posted by jpluimers on 2019/04/08
When one of the machine isn’t active for a while it seems to disappear. Even when it’s active some of the machines have intermittent errors pinging it as like every 10-30 seconds one of these ping results appear:
92 bytes from tl-er5120 (192.168.71.1): Redirect Host(New addr: 192.168.71.193) Vr HL TOS Len ID Flg off TTL Pro cks Src Dst 4 5 00 0054 05de 0 0000 40 01 644d 192.168.71.108 192.168.71.193
Sometimes even a simple
Request timeout for icmp_seq 6900
So I need to dig into ICMP “Redirect Host” .
It might be a simple ARP thing like mac mini – Why the different results for ping? Or why is the Time Capsule getting involved? – Ask Different [WayBack] but like usual stuff I bump into is of a more complex kind so I’ve archived at least these:
- ICMP – redirect host (5:1) – MikroTik RouterOS [WayBack]
- Directed ARP and ICMP Redirects « ipSpace.net by @ioshints [WayBack]
- ICMP redirects are ba’ad, mkay? [Google Cache as no WayBack]
- networking – Why do ICMP Redirect Host happen? – Server Fault [WayBack]
