  2. [ubuntu] Re: Internet Access great, flakey one-way LAN access

    sounds like tcp window scaling problems to me. But that is just a wild guess. I have had similar problems with Windows Vista/7/Server2008 and Linux as well. Differing implementations of RFC1323 do...

  9. [SOLVED] Re: Can AES be taken by a known-plaintext attack?

  12. [SOLVED] Re: Can AES be taken by a known-plaintext attack?

    I am no crypto analyst, but I would probably say "that depends". But to my knowledge there are not any. And I think even if there was, it would depend on how AES was implemented as well and for...

    [ubuntu] Re: IPTables Startup for NetworkManager Lucid

    Unless you have the need for complex NAT'ing, i would recommend skipping manual iptable configs and just use ufw.

  20. [ubuntu] Re: Help installing a Windows 7 ISO to USB So I can Install on another hd.

    Unfortunatly you can't do it purely from Ubuntu. Well you could, if you had access to a windows 7 system to copy the boot block. But if you could do that you would just use that box to make ISO to...

    WPA and WPA2 do not work in ad-hoc mode. It has to be unencrypted and i "think" WEP works. If you have to have WPA you will need to look into settting up for Master mode. Which is entirely...
