rancid suddenly stopped backing up devices
Dear All,
I had rancid installed couple of months back and working fine with no issuesi have rancid version 3.9 with viewvc 1.3.0
I just realized that any changes to most devices are not backed up.there is no update in revison version neither I receive mailIt stopped on sept 21 2022attached a screen shot of the firewall
changes to above device is done almost daily.i did run clogin deviceip and it logs in succesfully

appreciate if someone can advise and help in troubleshooting the issue
I checked the logs but there is no clue

Thanks and regards
simon
Re: rancid suddenly stopped backing up devices [ In reply to ]
I suspect something broke in your crond(7) or crontab(5)s, since manually invoking rancid seems to work.
It'll vary depending on your OS (which you didn't specify) but try looking in /var/log/cron for information.
The breakage may have come from an automatic OS update, but again, without details it's hard to guess.

But in any case, since clogin still works, it's probably not a RANCID issue at all. You still need to manually involve rancid (like cron would do) and see if that completes successfully or not.

Also, the problem could simply be email: maybe RANCID is working fine but the emails aren't making it out. I've run into this more than once when something external in the email chain changed.

You've a bit more basic UNIX troubleshooting to do before we start blaming RANCID, I'm afraid. Luckily people here will generally be able to provide some advice at the OS level, given adequate detail.

Re: rancid suddenly stopped backing up devices [ In reply to ]
OK! Having clogin work proves that RANCID can connect to the host and (I assume?) authenticate.
No change in the SVN/GIT/whatever-you-use could mean that either RANCID wasn’t able to retrieve the configuration, wasn’t able to parse the configuration, or wasn’t able to check in the new version to the repo.

Unfortunately, I’ve found RANCID’s own debugging output to be either nonexistent or unhelpful. I have run into a very similar situation in the past, but sadly I don’t remember what the problem was. I do remember I had to use system tools to find out what was wrong:

If you’re running on Linux, you have the strace(1) tool; on OpenBSD, you’ve got ktrace(1); on Solaris you’ve got truss(8); other UNIXes will have roughly-equivalent tools – all these are similar in that they will trace system calls for you and produce (somewhat-) meaningful output that may help you identify where the failure occurs. E.g. if it’s a permissions error, the strace(8) output may show you the EPERM error message, and if you look carefully, the path to the file in question. Generally speaking, the strace/ktrace/truss/etc. output will show a failure somewhere in the later part of RANCID’s execution that you can use as a starting point.

That’s all I’ve got, hopefully someone else has an easier suggestion.

if it were unable to commit the new version, you would see the same diffs
repeatedly.

I would review the logs for the group. if nothing there indicates the
problem, try the clogin tests outlined in the FAQ. If these work, verify
that the entry in the router.db is correct and the device is marked as 'up';
it would appears in the routers.up file too.

other useful tests are running rancid manually, like

rancid -t <type> -dl <devicename>

that shows misc parsing & logs, the commands run & filters called, the
exit value, and leaves <devicename>.{raw,new} output files.

then
rancid -t <type> -dl -f <devicename>.raw
can be used for further debugging that I would not expect to be useful to
most.

Re: rancid suddenly stopped backing up devices [ In reply to ]
Dear All,
Regarding the issue I had regarding any changes made in any of the devices already configured in rancid would not be backed up neither in ViewVC no revisions have been updatedSo I did a new test
1) creted a new group named Remore-Routers ---- was succesful2) added a new router add the neccesary to clogin  and tested using /usr/bin/rancid/clogin device ----- was sucessful3) updated the new router.db file
4) ran rancid-run

This is not necessarily an error. I assume that you know this, but
some changes are not reflected in the configuration because they are
defaults. You did not share what the change was nor what the device is
(possibly cisco), so I can not comment about whether is a default.

Is the device in the routers.up file? I can see here how a count of
devices in the log would be useful, back to Adam's comment.

An interface description is an simple change to trigger a rancid diff.

Make the change, then after rancid runs, look at the device file in
configs directory for the change. If it is there, but you did not
receive an email, look at the mail server logs for it being sent. If it
was sent, make sure it is not being procmailed/filtered away.

An interface description is an simple change to trigger a rancid diff.

Make the change, then after rancid runs, look at the device file in
configs directory for the change.  If it is there, but you did not
receive an email, look at the mail server logs for it being sent.  If it
was sent, make sure it is not being procmailed/filtered away.
