Hello,
Is it possible to test if a the name after the at-sign is a real domain?
If so, how can i do this?
I know you can test these with whois, but i'm wondering if this can
always succeed?

This is not entirely true, there are 100BaseTX ISA cards
available (e.g. the 3C515 from 3COM). Probably not the best
way to go though.

'Session' is a higher level abstraction, not really relevant to the
way Ethernet works. You don't negotiate the wire speed
end-to-end at all, just point-to-point (if at all). With a simple
hub on the left hand side of the gateway, you'ld have to set it
permanently into 10Mps mode to bring the link to the
gateway up at all.
>If "10mbps propagatrion" really takes place, does there any
>solution (like "wise hub") exist?
To connect 10 to 100 you need a device that buffers and
forwards packets - i.e. a bridge (switch). So, one set up
would be:
........................................
100hub --- switch --- 10 hub
| | | | |
..............................|........
| | | | |
GW---- to ISP
Now for the good news: devices with 100Mbps,10Mbps ports
and an internal switch, are often sold as 10/100 dual speed
hubs. Essentially the configuration between the dotted lines,
except ports are dynamically assigned to the 10 or 100 side.
Make sure that it is capable of simultaneously handling
10Mbps and 100Mbps connections (some of the older types
without an internal switch have a global 10 or 100 setting).

Hi
You should use Samba (ie program smbclient, which is similiar to ftp-program) to
get files from MS servers.

PS. There is a "new" book from SSC:Samba:Integrating Unix and Windows (ISBN
1-57831-006-7) which covers quite well all aspects of networks with mixed

Is it possible the environment variable ...
RESOLV_HOST_CONF
... is set ? If not *and* you can lookup hosts that are not in /etc/hosts
then I would say very strange things are going on at you ... very strange
things ...
Overlooking something simple, sure of that

The short answer is yes. The longer answer is also yes. Every flavor of
Unix that I have my mitts on allows comment lines anywhere in the file
beginning with an "#" and as long as the entries are white-space
delimited. ie: tab or space, everything will work as advertised.

Try putting a link from wherever your master web page goes (like,
default on a debian system for www.../index.html is /var/www) to /home
Then, your users don't even need a ~ in front of their names. Just an
index.html and they're all set.

Hi there, I am pretty new to Linux, but enthusiastic and want to show my

Yes. You need to build support for this into the kernel and read the
documentation that accompanies the kernel with regard to this facility.

First of all - take a look at the network config on the PC's or ask your
sys.adm.
If you run X with gtk installed, you can run a network surveillance program
called Cheops, which will show all the machines and their IP's on your
local network.
You can optain Cheops from
ftp://alge.anart.no/pub/network/cheops-0.59a.tar.gz
