Triggers for iTerm2 (example for Arista EOS)

Written by Arnaud 30 november 2020 no comments

I wrote some triggers to get colors when using iTerm2 (screenshot below) with Arista EOS but it should also work on Cisco IOSes with some minor tuning.

iTerm2 is a replacement for Terminal and the successor to iTerm. It works on Macs with macOS 10.14 or newer. It allows you to create Triggers. Triggers watch for text matching a regular expression to arrive in a terminal session and then perform an action in response. You can't import triggers from a file/profile but you can configure them on "Preferences, Profile, Advanced, Edit Triggers".

The whole options are detailed in the official documentation for triggers.

Dropping RPKI/ROA invalid routes on Arista EOS

Written by Arnaud 10 september 2020 no comments

If needed, please read my previous blog post to configure your RPKI/ROA validators and sFlow visualisation with pmacct/influxDB/Grafana. It's always better to see what you are doing :)

I found several interesting documentation on the Arista website :
- Standalone BGP Origin Validation with RPKI : https://eos.arista.com/bgp-origin-validation-rpki/
- Securing Inter Domain Routing with RPKI : https://eos.arista.com/sidr-with-rpki/
- BGP Prefix Origin Validation with Resource Public Key Infrastructure (RPKI) : https://eos.arista.com/eos-4-24-0f/bgp-prefix-origin-validation-with-resource-public-key-infrastructure-rpki/

This page is a memo of the useful commands I used (and some tips) :

Arista EOS : sync dir and files between supervisor cards

Written by Arnaud 17 april 2020 no comments

I know some files (like startup-config) are synchronized between supervisor cards on Arista chassis :

DCS-7508N(s1)#show redundancy file-replication 0 files unsynchronized, 5 files synchronized, 0 files failed, 5 files total.

File Status Last Synchronized ---------------------------- ------------------ -------------------- file:persist/secure Synchronized 45 days, 5:52:41 ago file:persist/sys Synchronized 0:04:05 ago flash:.assetTags Synchronized 45 days, 5:52:41 ago flash:startup-config Synchronized 0:38:59 ago flash:zerotouch-config Synchronized 45 days, 5:52:42 ago

But I could not find any way to synchronize my homemade scripts easily, so I wrote a script to do it :

I've added in a github repository some of the scripts I use for basic operations.
