Why is tampering with the TTL of IP dangerous? However - if you incremented packets which originated on your network to the value they would have had if they had originated on your router, then the return packets will reach your router (and then you can increment them when sending it onward to the client in the local network) |

Root Locked Out of Ubuntu 12.04? Was there not a user created in the admin group when you installed? Desktop ubuntu doesn't require editing sudoers to get sudo permission. Also, what's your VPS provider? You might be able to get tech support for this. |

Smoothest workflow to handle SSH host verification errors? Why not copy the old key over when reinstalling / reallocating a server? |

Why does 'pkill /?' kill my SSH session? @scooz As a general rule, unix commands almost never accept /? as a help command. Typically this also applies separately - they almost never use / for switches (- or -- are more common), nor accept -? for help [though there are a few that do that IIRC] |

Multiple Linux sysadmins working as root You should ssh out from your non-root account rather than from within sudo. |

Is there a section of ports reserved for in-house use? @voretaq7 if you need more ports, just use another IP address. But it's one IP address per device, not one port per device - adding more devices to the internet doesn't consume a port, each device has its own set of ports |

What is the recommended size for a linux /boot partition? I've been surprised relatively recently with a bios that couldn't access above 1023(?) cylinders, too. |

Will everyone having Globally Accessible IP's in IPv6 be kind of a security nightmare? Whether it was created for security reasons is separate from whether it has had a security effect [even if one characterizes that effect as "creating an arguably 'false' sense of security therefore making people less likely to implement real security features"] |

How to take full ownership of an IP address? (I am not a lawyer but) "there's no legal recourse for an unsubstantiated take-down request"? did your lawyer tell you this, or are you just repeating what you heard somewhere? Even if there's no specific provision (this isn't the DMCA, is it?); which law is it that exempts takedown requests from common-law libel? |

SSH Prompts for password even though private keys are available, presented to server and known to it If you don't enter your password, how will your home directory be decrypted when you log in? |

Relinking a deleted file This sort of functionality (See this question and answer) was specifically rejected as a security risk [to a hypothetical security scheme revolving around a privileged process giving your process a read-only file handle to a file you own but do not otherwise have access to]; I tried it (though with a small C program to directly use the relevant system call) and it did not work. |

Is it valid to have part of an IPv4 address set to zero? what about a broadcast address of X.Y.0.255? |

Relinking a deleted file This doesn't work; if the file is deleted it will fail. |
