[CentOS] CentOS 5.7 eth0, eth1 and arpwatch flip flops

2012-12-26 Thread Gavin Henry
Dear all, Has anyone experienced this whilst running DRBD over eth1 between two CentOS 5.7 servers? eth1 is a private IP address, unroutable. eth0 is the public address. CentOS will reply sometimes once every 3 days or every 14mins~ saying My public IP is on eth1 to arp requests when it's not,

[CentOS] Centralised logging with Gui and alerts?

2009-08-13 Thread Gavin Henry
Hi all, If logging all logs via syslog to a central syslog server that are all Centos based, what GUIs are out there to browse them etc. ? I know about splunk but don't want to go down that route. Also, some servers are hosted and would be best not sending their logs across the net to a central
