SNMP-Error & no rrd-files

[wedge1001]

Hi,
i've been trying to install the latest cacti to my debian server.
(unfortunately it has plesk on it - and i'm not allowed to do a complete reinstall)

i used apt-get to install cacti - this has worked fine.
i relocated the cacti sites to a place plesk is able to load the site (links are fixed, so that resource will point to the right folder)

But SNMP won't work.
if i create a new device i get an error at the top saying "SNMP error"

i've checked my config & tried smpwalk
the "walk" seems to work:
for example:

Code: Select all

#snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux <myserver.de> 2.6.32-5-amd64 #1 SMP Mon Jan 16 16:22:28 UTC 2012 x86_64

then i've rechecked the settings on cacti - i tried SNMP v1 and v2 - both won't fix the error.

i've checked the firewall settings - and even allowed every connection - but this asen't changed anything.

Someone got an ideas, because i haven't one anymore.

Thanks in advance

R.

Hi
thank you for your answer.
i've checked this.

but sestatus wans't found on the system and there are no directories available on the fs

so nope, no selinux or anything else like this is active.

Are you able to peform a wireshark trace to at least learn if some snmp request goes out from cacti?
R.

Hi,

thank you.
i've figured out that the server won't listen to any ports - even if the config was right.
Only an reistall has helped.

So now i've got a new problem - a well known one - i can't create the rrd-files.

thank you for your help.
i'll try to find a solution for my problem in the forums here. if i won't find any solution i'll write again ^^


edit
i reinstalled via apt-get - but it hasen't created a new user.
cat /etc/passwd wont' show me a cacti user -.-

i've checked permissions - they're ok.
i can write to the rra folders if i do this manually.

i've checked the status of the device. It's up.

but the system won't create me a rrd-file :/
i dunno what to do -.-

[gandalf]

I just noticed that you're running php safe mode. I'm not an expert on this but I'm quite sure that this is not a good idea when running cacti
R.
