This week Greg, Mike, Dave, and Alex fail at using Zencastr for the first time. We have failed back to the old audio…it is a sadness. 🙁
This week we talk about:
Zencastr
Feature Request Doc
Ubiquiti v Cambium
Ubiquiti LTU
UniFi Certification
ChiNOG
NANOG
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
Greg was today years old when he learned IPv6 doesn’t do fragmentation. Path MTU Discovery.
Limit MACs per interface on a Mikrotik.
Danny is trecking through the US soon; he needs mega uploads for his videos…anyone wanna help?
Nobody is looking at the same internet.

This week Greg, Tomas, Dave, and Nick never stop never stopping. This is a long one, so put it on 2x speed and kick back 😉
This week we talk about:
Jim Jones recorded his tips video, thanks!
Cambium CNheat
Ubiquiti unifi access – access control system(strike and mag control)
Ken asks about VRRP on the inside and outside interfaces at the same time…how to have one transition when the other does.
Jim Jones was asking about a light web proxy, would Mikrotik work.
Michael Rhone asks for opinions on “Why run ipv6 in a small network?” – of course Nick says “Why would you not” LOL
Taking on custom projects – what are the signs you are in danger, and when to day no.

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.

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
This week Greg, Tomas, and Dave talk about how we are getting into beach shape…or perhaps we just talk tech 😉
This week we talk about:
White label PCI compliance scanning.
Unimus is awesome – mass config push
Mikrotik try catch block
*Slack Updates*
What’s in your backpack. Aside from the common Some things are: lock picks, small multimeter, 6 inch industrail laptop
Tomas found a cli wireshark tool
sngrep – realtime SIP packet viewer
IPv6 routing subnets without routing?
Controlling traffic flow when BGP peering with the same ISP twice – MED vs Prepending
ZeroTier Opensource SDN doesn’t do multipathing yet
Bridge appliance resilancy – second link bypassing it shutdown by STP(Mikrotik to Netonix)
Customer silence, not always a good thing – either acceptance or they’ve given up. Out communicate them.
Basic router configuration for business customers.
