Newbie questions

[Inge Thorin Eidsaether <webdude@phreaker.net>]

Hi all!

I'm a newcomer to Debian from FreeBSD, and have a couple of questions 
some of you guys may know the answer to:

1 - I keep getting console messages about 
    'eth0: link up, 100Mbps, full duplex, lpa 0x41E1' and 
    'eth0: link down'. These two messages alternate regularly. 
    When the link is down, of course I cannot connect to anything. 
    Also, how do I avoid getting these annoying messages? 
    
2 - Doing a 'man-k <some_command>' (or man -f <some_command>) does not work.
    Is there a misconfiguration somewhere? 

3 - How do I go backwards in a man page reading? Looks like 'more' is used to 
    page the ouput to screen, but 'b' or ^B does not work here. 
    Silly question, maybe...

I am running Debian GNU/Linux 3.0 with linux kernel 2.4.20 (latest stable).
The NIC is a AMD PCnet32, and gets it's IP from an ADSL router by DHCP. 
Here's some dmesg ouput:

pcnet32.c:v1.27b 01.10.2002 tsbogend@alpha.franken.de
pcnet32: PCnet/FAST 79C971 at 0x7800, 00 60 b0 f7 7a 20
pcnet32: 1 cards_found.
eth0: registered as PCnet/FAST 79C971


Grateful for any help!

yours,
