[olug] SMB transfer speeds

[Vincent.Raffensberger at dtn.com]

The kernel ring buffer is of a limited size.  Old boot messages will 
disappear from it rather quickly if ipchains/tables are logging messages.
None of the tools mentioned here are distro specific.  They also allow you 
to make changes w/o rebooting to test configurations.  That's what they 
are for.

Silly people indeed.

Why depend on some tools when ya can just read your boot up messages ? 
Why post distrobution specific stuff ?

Just do a `dmesg`, or a `dmesg | grep eth` or something to see what it's 
configuring as.  Silly people afraid of the shadows.

PS

Has the Millard Computer Fair been interesting at all over the last 3-6 
months ? I've not been due to it's extreme lack of variety.  Not to 
mention the lack of interesting items.
