snmp works, but wont retreive data..

[phriday613]

ok.. i got snmp working on my computer. If i run

snmpwalk localhost public

it outputs ALOT of snmp stuff.. the uptime, interface stuff, etc.
so, my question is, when i open the "snmp interfaces" part of cacti, and added the hostname=127.0.0.1 and community=public

the interfaces screen shows this: BUT if i check snmpwalk 127.0.0.1 public interfaces.inTables
it will output this: http://kickinitwitmilhouse.no-ip.com/snmp.jpg

[michael@moe etc]$ snmpwalk 127.0.0.1 public interfaces

interesting.. it shows my information!!!
however, when i do "refresh interface" now i get this:


Warning: Cannot add header information - headers already sent by (output started at /var/www/html/cacti/include/snmp_functions.php:264) in /var/www/html/cacti/snmp.php on line 72

i dunno what that means, but im gonna go tinker with the graph. I tried to put this "snmp_functions.php" file in the cacti folder, under the filename "snmp.php" and it wouldnt work before. My stupid mistake!
Thanks for clarifying it, but would anyone have a clue what the error means??!

also, is it possible to monitor other comptuers on my LAN? do they need SNMP on them as well or can this comptuer point to them??
