Issue
Under Host Groups have the following problem the uptime on router is listed as critical, (Service Check Timed Out)
Log file has the following entry Warning: Attempting to execute the command "/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: Uptime\nHost: RD Cisco 8818\nAddress: 192.168.xxx.xxx\nState: CRITICAL\n\nDate/Time: Wed Nov 28 12:49:00 CST 2012\n\nAdditional Info:\n\n(Service Check Timed Out)\n"

Manually running check_snmp and it hangs.
/usr/local/nagios/libexec# ./check_snmp -H 192.168.xxx.xxx -o iso.3.6.1.2.1.1.3.0 -c comname -p2c
Run ps -aux | grep snmp I get the following;
/usr/bin/snmpget -t 1 -r 5 -m ALL -v 2c -c 192.168.xxx.xxx:161 iso.3.6.1.2.1.1.3.0

When I manually run snmpget it will return;
snmpget -t 1 -r 5 -m ALL -v 2c -c comname 192.168.xxx.xxx:161 iso.3.6.1.2.1.1.3.0
iso.3.6.1.2.1.1.3.0 = Timeticks: (406909583) 47 days, 2:18:15.83

The community name is not being passed, is this normal?
I have the proper community name listed in switch.cfg, not sure what else I can do first pass at setting up and using nagios.
Using Ubuntu 12.10 fresh install.

That is very unusual... I've never seen that before... I think your best bet for this problem might be to ask the plugin developers: http://nagiosplugins.org/support
