59 | ssh ohne password von localen zum entfernten Rechner | Auf dem localen Rechner:
% ssh-keygen -t rsa
Es fragt nach dem passphrase. Man less es blank
Das generiert die dateien ~/.ssh/id_rsa und ~/.ssh/id_rsa.pub
auf dem entfernten Rechner �ftet man mit einem editor
~/.ssh/authorized_keys und kopiert man die zeile von id_rsa.pub des Servers.
Achtung, diese zeile ist sehr lang |

option domain-name "unibe.ch";
option domain-name-servers 130.92.4.41, 130.92.9.50;
}
Example von Internet:
Führen Sie als root folgendes Kommando aus:
route add -host 255.255.255.255 dev eth0
Sollte die Fehlermeldung
255.255.255.255: Unknown host
auftreten, dann tragen Sie folgenden Eintrag in Ihre /etc/hosts ein:
255.255.255.255 dhcp
Ist dieser eingefügt setzen Sie folgendes Kommando ab:
route add -host dhcp dev eth0

# Sample /etc/dhcpd.conf
# (add your comments here)
default-lease-time 1200;
max-lease-time 9200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.1, 192.168.1.2;
option domain-name "mydomain.org";
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.100;
range 192.168.1.150 192.168.1.200;
}
Dieses Beispiel erlaubt dem DHCP Server einem Client IP Adressen im Bereich von 192.168.1.10-192.168.1.100 oder 192.168.1.150-192.168.1.200 zuzuweisen.
Wenn der Client keine größeres Zeitfenster anfordert vergibt der DHCP Server eine IP Adresse für 1200 Sekunden. Das maximal erlaubte Zeitfenster für die Adreßzuordnung durch den Server beträgt 9200 Sekunden. Auf Anfrage sendet der Server dem Client die folgenden Parameter:
Benutze 255.255.255.0 als Subnetzmaske
Benutze 192.168.1.255 als Broadcastadresse
Benutze 192.168.1.254 als default Gateway
Benutze 192.168.1.1 und 192.168.1.2 als DNS Server.
Um Windows Clients einen WINS Server zuzuordnen ist in der dhcpd.conf folgende Option notwendig:
option netbios-name-servers 192.168.1.1;

45 | Mac: Sharing files with Windows users | You can share the files on your computer with Windows computer users using SMB/CIFS.
Open System Preferences, click Sharing, and turn on Windows File Sharing in the
Services tab.
Then, still in System Preferences, open Accounts preferences and create a new user
account for each Windows user you want to share with. In the user's settings, be sure to
select "Allow user to log in from Windows."
If you can't log in to your Macintosh from a Windows computer, reenter your user account
name on the Windows computer using all lowercase characters, reenter the password for
the account exactly as you entered it in Mac OS X, then log out and log back in to the
Windows computer using the new name and password. |
