    I have install Sarge using instructions from http://www.howtoforge.com/perfect_setup_debian_sarge, everything was great! And when I try to edit file /etc/network/interfaces/, I've get the magic answer: Permission denied! When I try call other files, I haven't other answer. What's this problem? Root have full permissions default, but system say me "get out!" Why?
    Serriously, how can I to continue my work?

    Please try first the command "su" to go to root (and to make shure your really root).
    Then use an editor like "vi" to edit the config file. It was reported taht some other editors (mostly KDE or Gnome GUI Editors) are giving permission denied errors on files even for the root user.

    You could also just use pico.

    It's much easier than vi but die-hard vi-ers will most probably argue with me.

    If I use 2 network adaptors (eth0 for Internet, eth1 for LAN), should I type all IP-addresses etc. in file /etc/network/interfaces or create different files?

    No, it's still /etc/network/interfaces. You have sections in it for lo and eth0, so simply create a new section for eth1. :)

    And as gateway for eth1 sould I set the IP of eth0? (i will use this mashine as gateway LAN - Internet)

    Hm, I think you have to do that with iptables rules. Maybe you should google for something like "Debian router howto" or so...
    If you only need that box as a router, then I'd recommend that you install IPCop on it. http://www.ipcop.org/
    Easy to install, and very secure. :)

    I have edit /etc/network/interfaces so:

    #The loopback network interface
    auto lo
    iface lo inet loopback

    #The orimary network interface
    auto eth0
    iface eth0 inet static
    address <external IP of my box>
    netmask 255.255.255.240
    network <IP of external network>
    broadcast <broadcast IP of external network>
    gateway <IP of provider's router>
    # dns-* options are implemented by The resolconf package, if installed
    dns-nameservers 127.0.0.1
    dns-search <mydomain>
    #The secondary network interface
    auto eth1
    iface eth1 inet static
    address 192.1668.5.5
    netmask 255.255.255.0
    network 192.168.5.0

    And where I restart networking, I get:

    Setting up IP spoofing protection: rp_filter.
    Reconfiguring network interfaces...ifup: interface lo already configured
    eth0: link down
    SIOCSIFADDR: no such device
    eth1: ERROR while getting interface flags: No such device
    SIOCSIFNETMASK: No such device
    eth1: ERROR while getting interface flags: No such device
    Failed to bring up eth1.
    done.

    Device is good, physical installed, by setup and lspci detected.
    Maybe file is incorrect?

    This is not a valid IP:

    address 192.1668.5.5

    Can you try to re-boot your machine so that the correct network card driver can be loaded? Hopefully the driver is included in your kernel or available as a module (in the latter case you might have to include it in /etc/modules).

    Setting up in expert26 mode has ask me for boot modules for 2 my ethernet cards. But this time setup was down because of unstable power. Next time I did setup with your instructions, in mode linux26, without this question. If I re-install the system one more time in expert26 mode, can I get correct driver? Just I'm not sure, that I can found and install this module manually quick, and expiriens-time is limited... :confused:
