Hi again.

I'm sorry to waste bandwith again, the last messages I sent were
sent from Lotus Notes in compressed format, I deeply regret that.
Here is the message once again, hopefully uncompressed.

It looks like:

/etc/resolv.conf
domain	dk
lookup	file bind
nameserver	193.162.146.9
nameserver	193.162.153.131

and btw, I haven't got my nameserver running yet, does it mean that
I should avoid 'lookup bind'?

I have tried removing the bind option, but then I can not resolve any
addresses not specified in /etc/hosts. According to the resolv.conf
man-pages the order for name searching is specified with the lookup
statement, but it does not appear to work as intended. It seems to
me that my 'netstat -r' first makes a DNS-lookup, and when timed out
it looks for the names in the /etc/hosts file. Shouldn't it have been
the other way around?



I tried to remove /etc/resolv.conf and then the 'netstat -r' worked
without any delay, but I still can not ping the gateway :-(

A tcpdump command shows lot of output like:

13:29:58.253800 arp who-has 192.168.80.120 tell (0xcc02e) 192.168.80.254
13:29:58.404383 arp who-has gateway tell (0xcc02e) nethotel.dk
13:30:00.069319 arp who-has 192.168.88.80 tell (0xcc06a) 192.168.80.254
13:30:00.069320 arp who-has 192.168.80.213 tell (0xcc0ba) 192.168.80.254
13:30:00.075303 arp who-has 192.168.88.62 tell (0xcc10a) 192.168.80.254
13:30:00.283939 arp who-has 192.168.89.24 tell (0xcc15a) 192.168.80.254
13:30:01.831142 arp who-has 192.168.93.63 tell (0xcc1aa) 192.168.80.254
13:30:03.409312 arp who-has gateway tell (0xcc1fa) nethotel.dk
13:30:04.286115 arp who-has 192.168.89.48 tell (0xcc236) 192.168.80.254
13:30:05.289745 arp who-has 192.168.89.24 tell (0xcc286) 192.168.80.254

so obviously there is connection to the (outside world) cable-network.
(I guess the lines not mentioning gateway are from other users on the
cable-network). But what does the above lines really tell me?
(Obviously nothing :-)

Don't bother to answer, I read the tcpdump man-pages and got wiser!


Another question:
I do not have any apropos-help ready. I know there is a database
I have to build (because I have done it before in v1.2 I think), but
I can not remember the name of the db or how to build it. And I
can not find anything in the man-pages as the apropos is not working
properly :-(
