Re: [root () student6 rug ac be: student6 05/14/01:16.02 system check]

Harmless.  It means that 195.6.82.132 has a broken TCP stack and the 
Linux kernel is simply being a tattle-tale.  Later versions of the 
kernel have this message removed since it was deemed as yet another 
remote implementation bug that couldn't be avoided.
