Hi Eric, increasing the snmptimeout from 2 sec. to just 3 sec. in the
netdisco deployment.yml solved the problem! Now the modules are
showing back again fine. Thank you!

For these nodes perform a search by mac with the archive option
selected to see what other switch port(s) matches show up in the
list. Most likely an uplink should be in the list. If so:
1) Does each end of the uplink show the opposing neighbour, or does
only one side?
2) Is the uplink using a L2 discovery protocol (CDP, LLDP, etc) or a
manual topology entry?
3) Is the uplink part of a port-channel or some other link aggregation
protocol?
Is this behaviour limited to a specific vendor or model?
What version of netdisco are you running?
Hi Eric,
When I visited the particular device once more, I noticed that now there
are different nodes not showing up!
See: http://iweb.noa.gr/files/nd2/no_arch_data_20140523a.png
and: http://iweb.noa.gr/files/nd2/with_arch_data_20140523a.png
Now affected ports (showing as "up", but without nodes) are: 2, 3, 6, 9,
10, 14, 15, 17, 20
Doing a search as you advised for the MAC addresses of nodes connected
on ports 2, 3, 6, I get the following results:
http://iweb.noa.gr/files/nd2/fa02-node.png
http://iweb.noa.gr/files/nd2/fa03-node.png
http://iweb.noa.gr/files/nd2/fa06-node.png
To answer you questions:
1. I don't see uplinks in the search results.
2. We are generally using CDP
3. No link aggregation or port-channel used.
Almost all our switches are Cisco 2950 / 2960 (various types
with/without optical interfaces) and a couple of SRW2024-K9. I see the
behaviour on all.
We are running latest netdisco (2.027004) with SNMP::Info 3.13.
Best regards,
Nick

the header is not there, so it's apache.
But with some trial and error I got the X-REMOTE_USER to work
RewriteEngine On
RewriteCond %{LA-U:REMOTE_USER} (.+)
RewriteRule . - [E=RU:%1]
RequestHeader unset X-REMOTE_USER
RequestHeader add X-REMOTE_USER %{RU}e
So after the 401 popup to enter user/password, I am automatically logged in
netdisco and I see my username in the "logged in as" space. But if i try to
use any of the links I get a Not Found from apache which is redirecting me
to he /login url.
I clicked on the port utilization report and got redirected to:
netdisco.domain.tld/login?return_url=%2Freport%2Fportutilization
for instance, when on the home site I do a mouse over 'System information'
the link under it is : http://netdisco.unix.domain.tld:5000/# . Behind the
proxy, it becomes:
https://netdisco.domain.tld/login?return_url=%252Finventory#
so I am having some troubles with the reverse proxy I do not seem to be
able to resolve on my own. Tips welcome ;-)
TIA,

I added
log: debug
to environment.yml and I see this in netdisco-web.log
[5836] debug @0.521952> No such user xxxx
[5836] debug @0.524081> No such user xxxx
[5835] debug @0.439999> No such user xxxx

[5837] debug @0.523004> No such user xxxx
[5837] debug @0.525105> No such user xxxx
so the x-remote-user is being set but not used, it seems. That's why it is
redirecting to the login url.

hi,
maybe useful to someone else. We use very simple init scripts in our centos
