If the MIB is reporting the right thing and netdisco is not finding it, then this is probably the problem that bz pointed out yesterday that "netdisco -r" isn't seeming to work, while "netdisco -R" is. The whole system is built around the idea that "netdisco -r" will work, so I recommend debugging that (e.g., looking at the logs).

/usr/local/netdisco/netdisco you mean;  I have now learnt that just
startuing netdisco picks up the config file from
/usr/loca./etc/netdisco and not the one from /usr/local/netdisco aka.
/home/fenner/src/netdisco and it seems the default config files were
never ever touched.

This may explain the one or other strange things... like why the
pasted command from the nightly cronjob did work and the discover loop
did work but just running netdisco -r did not do updates.

It doesn't explain why the DB entry was never updated as discover-loop
seems to call it with the full path and was otherwise working.  I
guess at this point that this field is not updated unless there is
another change condition on the entry forcing it to update.

It seems the sw-noc is indeed reporting the right thing:

Though 43 days is a slight overestimate I fear.... Silly NTP?



Anyway.....  time to cause (no) trouble.
