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

5) In Viewvc browser I could see the entire router config under root/cvsroot/Remote-Routers/configs
Now I did some changes to the above Router and then ran /usr/local/rancid/bin/rancid-run it finsihed with no errorsbut the was no new revicsion in viewvc as used to be the case before sept 21 2022 .
Also when I checked the logsThe first time when rancid was run the logs showed

So it seems when I add a new device to rancid it works but the next time it does nothing
any advice and troubleshooting help would be highly apprecited

yes.

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.
> 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.
what did you find to be missing? Tell me so that I can try to improve the
debug output.
