[rancid] Juniper CLI prompts out of sync causing frequent changes

[Chris Wopat]

Hi folks,

Last year I commented on an issue we're seeing across many Juniper devices.
I neglected to follow up on Heasley's response then but are seeing it a lot
more frequently now, perhaps related to some OS upgrades or something else.


Thread was here:

Looking at the last week or so of these we've had, they're on devices
running 14.1X53-D4*, which is primaraily QFX5100 but also a few EX4200.

Here's output from a single diff, its like this on various commands nearly
every run:

Heasley, you chimed in saying the prompt may be out of sync. While I don't
quite know what that means, you suggested sending output of:

eval `rancid -Ct juniper device`

Here that is, finally:

jlogin -t 120 -c 'show chassis clocks;show chassis environment;show chassis
firmware;show chassis fpc detail;show chassis hardware detail;show chassis
hardware models;show chassis routing-engine;show chassis scb;show chassis
sfm detail;show chassis ssb;show chassis feb detail;show chassis feb;show
chassis cfeb;show chassis alarms;show system license;show system
boot-messages;show system core-dumps;show version detail;show version
invoke-on other-routing-engine;show configuration;file checksum md5
/var/db/scripts/*/*;file list recursive /var/db/scripts/' r-platteville-hub

You may notice some additions at the end which help us track some slax
scripts:

file checksum md5 /var/db/scripts/*/*;file list recursive /var/db/scripts/'

we've had those in place for quite some time (before this) so I'm unsure if
those are related.

Cheers,
Chris
