Dan was having unifi APs with wireless backhauls not find the controller and fall back to default 192.168.1.20 addressing. Miller says turn off “Uplink Connectivity Monitor” under unifi settings > site

TheBrothersWISP Jim Jones’ Top 5 Tips



This week Greg talks to Jim Jones about his top 5 tips.

The Tips:

1. Show up.
– If you’re early you’re on time. If you’re on time you’re late. If you’re late, you’re fired.
– Never be late… especially to a client.
2. KNOW DNS.
– It’s never DNS… till it is.
– Use DNS!
3. Be humble. Ask for help.
– Have a network of peers.
– Don’t wait too long to call support! That’s what they’re there for!
4. Backup all the things.
– File data
– Systems
– Configs
5. Don’t be married to vendors. Use the right tool for the job.
– Windows vs Linux
– Mikrotik vs Cisco
– Cisco SMB vs Bruhcade
– Unifi vs Meraki
6. Bonus: Learn. Go outside your comfort zone, silo.
– Podcasts.
– Books, audio.
– Youtube, pluralsight, etc.
7. Bonus: Teach. Mentor. Give more than you take.
– Don’t limit this to tech.
– True happiness is in serving others.

Unimus Fails To Discover ASR9000 IOS-XR Routers Via Telnet

It appears that Unimus has an inter-connection timeout of 250Ms, and when telnetting to a Cisco ASR9K it needs to be adjusted to something more like 1 second.
It seems that when a telnet session is opened to cisco via the discovery mechanism(trying to figure out if telnet is open), then instantly tries another connection to login, the Cisco router will fail the connection. Changing this timer puts more of a gap in this process which prevents the failure. I likely got something wrong in the translation there, but you get the idea.

The Unimus wiki shows you how to adjust timers.

The line in particular is:

-Dunimus.core.inter-connection-delay=1000
