Re: [rancid] Juniper CLI prompts out of sync causing frequent changes
We actually do not have a banner, but your mention of that reminds me that indeed, when doing some updates recently we enabled login-tip ( https://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/login-tip-edit-system.html/) which is almost certainly putting something random in a banner-ish area upon each login. Here are 3 random examples from the same device: Password: --- JUNOS 14.1X53-D47.3 built 2018-05-10 21:38:01 UTC JUNOS tip: Use the 'no-more' CLI pipe to disable the CLI's more capability and let the multiple pages of output scroll without stopping. --- JUNOS 14.1X53-D47.3 built 2018-05-10 21:38:01 UTC JUNOS tip: Use ESC-/ in the CLI to expand strings into matching words from the command line history. Password: --- JUNOS 14.1X53-D47.3 built 2018-05-10 21:38:01 UTC JUNOS tip: Use the TAB key to autocomplete interface names in operational mode. Since they liberally use dashes, single quotes, forward slashes and so on- this seems to be the likely culprit? Would it be possible to filter out anything between "JUNOS tip" and the first valid prompt so we have a chance of leaving them enabled? --Chris On Fri, Jul 27, 2018 at 12:00 PM, heasley wrote: > Fri, Jul 27, 2018 at 08:18:08AM -0500, 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: > > > > http://www.shrubbery.net/pipermail/rancid-discuss/2017- > October/009916.html > > http://www.shrubbery.net/pipermail/rancid-discuss/2017- > October/009922.html > > > > 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: > > > > > > > > Index: configs/r-kettlemoraine-hub > > === > > retrieving revision 1.144 > > diff -u -4 -r1.144 r-kettlemoraine-hub > > @@ -1,7 +1,8 @@ > > #RANCID-CONTENT-TYPE: juniper > > # > > # r-kettlemoraine-hub> show chassis clocks > > + # show chassis environment > > # r-kettlemoraine-hub> show chassis environment > > # Class Item Status > > # Power FPC 0 Power Supply 0 OK > > # FPC 0 Power Supply 1 OK > > Index: configs/r-lacrossecity-hub > > === > > retrieving revision 1.108 > > diff -u -4 -r1.108 r-lacrossecity-hub > > @@ -15,9 +15,8 @@ > > # FPC 0 Fan 2OK > > # FPC 0 Fan 3OK > > # > > # r-lacrossecity-hub> show chassis firmware > > - # show chassis fpc detail > > # Part Type Version > > # FPC 0uboot U-Boot 1.1.6 (Jun 5 2012 - > > 02:24:53) 1.0.0 > > # loader FreeBSD/PowerPC U-Boot bootstrap > > loader 2.4 > > # > > Index: configs/r-platteville-hub > > === > > retrieving revision 1.274 > > diff -u -4 -r1.274 r-platteville-hub > > @@ -1,7 +1,8 @@ > > #RANCID-CONTENT-TYPE: juniper > > # > > # r-platteville-hub> show chassis clocks > > + # show chassis environment > > # r-platteville-hub> show chassis environment > > # Class Item Status > > # Power FPC 0 Power Supply 0 OK > > # FPC 0 Power Supply 1 OK > > > > Heasley, you chimed in saying the prompt may be out of sync.

I presume you have a banner with something that looks like a prompt; like https://www.juniper.net/documentation/software/junos/junos93/swconfig-system-basics/configuring-a-system-login-message.html. if not, you'll have to share output with me. eval `rancid -t juniper -C hostname` &> output ___ Rancid-discuss mailing list Rancid-discuss@shrubbery.net http://www.shrubbery.net/mailman/listinfo/rancid-discuss
[rancid] Juniper CLI prompts out of sync causing frequent changes
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: http://www.shrubbery.net/pipermail/rancid-discuss/2017-October/009916.html http://www.shrubbery.net/pipermail/rancid-discuss/2017-October/009922.html 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: Index: configs/r-kettlemoraine-hub === retrieving revision 1.144 diff -u -4 -r1.144 r-kettlemoraine-hub @@ -1,7 +1,8 @@ #RANCID-CONTENT-TYPE: juniper # # r-kettlemoraine-hub> show chassis clocks + # show chassis environment # r-kettlemoraine-hub> show chassis environment # Class Item Status # Power FPC 0 Power Supply 0 OK # FPC 0 Power Supply 1 OK Index: configs/r-lacrossecity-hub === retrieving revision 1.108 diff -u -4 -r1.108 r-lacrossecity-hub @@ -15,9 +15,8 @@ # FPC 0 Fan 2OK # FPC 0 Fan 3OK # # r-lacrossecity-hub> show chassis firmware - # show chassis fpc detail # Part Type Version # FPC 0uboot U-Boot 1.1.6 (Jun 5 2012 - 02:24:53) 1.0.0 # loader FreeBSD/PowerPC U-Boot bootstrap loader 2.4 # Index: configs/r-platteville-hub === retrieving revision 1.274 diff -u -4 -r1.274 r-platteville-hub @@ -1,7 +1,8 @@ #RANCID-CONTENT-TYPE: juniper # # r-platteville-hub> show chassis clocks + # show chassis environment # r-platteville-hub> show chassis environment # Class Item Status # Power FPC 0 Power Supply 0 OK # FPC 0 Power Supply 1 OK 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.
