Environment Monitoring

Setup an APC AP9319 Environment monitoring unit today. It has temperature and humidity probes to do basic environmental monitoring of the are surrounding a rack. I’ve got it rigged up to a light beacon to flash an orange strobe and send an email if the alert criteria is met. See AP9319

According to APC, the AP9319 has since been replaced by their uber expensive NetBotz Rack Monitor 200. It seems like it offers more than you would actually need for individual zone monitoring.

Exim problem

While attempting to send outgoing mail through our exim relays, our Qmail mailbox was saying:

@400000004b60848425285634 delivery 12799: deferral: Connected_to_216.120.xxx.xxx_but_connection_died._Possible_duplicate!_(#4.4.2)/

On the relay : 2010-01-27 13:25:31 1NaCa3-0000zJ-AT demime acl condition: error while creating mbox spool file 2010-01-27 13:25:34 1NaCa3-0000zJ-AT H=smtp-2.******.net [216.120.xxx.xxx] F=<sherry@domain.com> temporarily rejected after DATA

This was resolved by clearing out the 30,000+ directories in /var/spool/exim/scan on the exim relay server left over from clamd scanning.

/etc/rc.d/init.d/exim stop; cd /var/spool/exim/scan;  find ./ -type d -exec rm -rf {} \; /etc/rc.d/init.d/exim
