TCP OFFLOADING --- INCORRECT CHECKSUM

I am able to telnet on a port at remote machine. However, I am unable to send packets on a connected socket. I run the command (ethtool -k rx off tx off) and then I am able to send packets on same connected socket and then application working accurately.

My Query is, why I need to off rx and tx ?

Log rotate for centralize rsyslog server

A centralized Rsyslog server is configured and working fine. Under /var/log path, every machine has its own separate folder for log keeping. For example /var/log/node1, /var/log/node2 and so on. I want every node under /var/log path keep last 6 months logs only.

Re: Howto simulate redis failover

Thanks for your suggestion. XXXX service is only bind with PUBLIC_VIP and we keep it after XXXX service [ because we want to receive connections only when our application gets online]
The VIP is bind with REDIS and dependent on VIP that is why I started VIP first for REDIS
