"The present need for security products far exceeds the number of individuals capable of designing secure systems. Consequently, industry has resorted to employing folks and purchasing "solutions" from vendors that shouldn't be let near a project involving securing a system." — Lucky Green

Rsync: remote source and destination It would involve a remote src rsyncd sending data to a remote dest rsyncd. You can work around it by ssh'ing to the src system and invoking rsync. |

Shell script to notify when CPU usage goes to 100% It's worth noting that "load average" has different meanings across different systems. What may be true for the Linux kernel is not true for OpenBSD. Make sure to understand what you are monitoring. |

How to ban IPs trying to login as root with ssh Why would you do this? If root can't login, there's no benefit from blocking IPs that try. |

ssh suddenly stopped working on Mac I would sometimes see the exact same problem when I connected with ssh from my OpenBSD laptop to some Ubuntu machines. I could always type into the session and run commands, though. Dropping the connection and reconnecting would work so I never really looked into it. Does it happen on every connect? Can you do 'ssh example.com echo hello'? |

ssh suddenly stopped working on Mac It's not your ssh client. You're in an interactive session. Try typing 'ls' and see if you get any output. I'm willing to bet that you do. |

Troubleshooting strategy for very poor iSCSI/NFS performance I took another look. Flow control was disabled and PAUSE counters were zero on all interfaces. Enabling flow control made PAUSE counters shoot up by 25% of the packet count. We've identified some hardware that doesn't show the same weak performance so now we're looking to update nic drivers and replace certain nics with more capable ones. QoS was already disabled on the switch. Thanks for your input. |

Troubleshooting strategy for very poor iSCSI/NFS performance @SpacemanSpiff: Flow control is not enabled. Would you expect that to make a difference? It's a ZyXEL GS2200. |

Working out some quirks of a master SSH server Security should be easy, not hard. Running both SSH and IPsec just makes it harder for the user and exposes much more code to the internet. Besides, those hosts are already running PHP and the attacker may freely choose his point of attack. PHP and related applications are much easier to attack than a modern sshd is. |
