The Qualys Threat Research Unit (TRU) has discovered a Remote Unauthenticated Code Execution (RCE) vulnerability in OpenSSH server (sshd) in glibc-based Linux systems. Using the VPC flow log default pattern available in DPL Architect, we can extract the meaningful fields to see only the network traffic targeting the SSH port.

All-traffic monitoring, analysis on demand—network performance management started to grow as an independent engineering discipline. By 2001, we won our first loyal customers. This approach works as long as application traffic can be decrypted. However, this approach didn’t scale as the applications and networks grew.

To speed up the above query we need to create an appropriate index so that the query can be executed in minimal time and have less impact on server performance. If we are using binlog_format as ROW, a huge number of bin logs would be created which could choke I/O of servers and require extra cleanup. What is partitioning?

Oracle VM Server is based on Xen. I came up with a great demo where I could break Solaris 9 and 10 servers in the same way, then demonstrate how it would take an hour and a reboot cycle to fix Solaris 9, but minutes and no reboot to fix Solaris 10. When I first joined Sun in 2001, it was believed that Sun was too big to fail, as well.
