Code:

iwconfig wlan0 essid MICRO-PROCESS.BRIBIR;
iwconfig wlan0 channel 11;
iwconfig wlan0 key s:[my key];
ifconfig wlan0 netmask 255.255.255.0;

ifconfig wlan0 up;

only i don't know how can i setup my gateway...

Hi,

If you 'man route';

Quote:

excerpt from 'man route';
example:

route add default gw mango-gw
adds a default route (which will be used if no other route
matches). All packets using this route will be gatewayed
through "mango-gw". The device which will actually be used for
that route depends on how we can reach "mango-gw" - the static
route to "mango-gw" will have to be set up before.

Everything is in the 'man route', 'man' is your friend.

Code:

~#route add default gw 192.168.0.1   # change to your IP

Code:

~# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         192.168.0.1     0.0.0.0         UG    1      0        0 eth0

BTW, it's 'wireless'.

i have tried with it, but if i add gateway 192.168.0.1 and netmask 255.255.255.0 it says that it is imposible to add that netmask to 192.168.0.1

Hi,

Post the output of 'route -n' and 'ifconfig -a'.

here it is:

Hi,

You have not defined a gateway. No gateway in your routing table.

n0p.cracker · 05-14-2008, 09:30 AM

yeah i know, how can i delete:

Code:

192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 wlan0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo

i have red man but it won't :P

LordAnta · 05-14-2008, 10:10 AM

just type as root in a konsole:

Code:

 route add default gw 192.168.0.1                 # this is to add the gateway
 echo "nameserver 192.168.0.1" > /etc/resolv.conf # this is to add the DNS to use

But, instead of setting the IP manually, why dont't you use dhcp??
Replace

Code:

 ifconfig wlan0 netmask 255.255.255.0;
 ifconfig wlan0 192.168.0.21;
 ifconfig wlan0 up;

with

Code:

  ifconfig wlan0 up
  dhclient wlan0

You should read the 'man route';

Quote:

~# man route

excerpt from 'man route'

DESCRIPTION
Route manipulates the kernel's IP routing tables. Its primary use is
to set up static routes to specific hosts or networks via an interface
after it has been configured with the ifconfig(8) program.

When the add or del options are used, route modifies the routing
tables. Without these options, route displays the current contents of
the routing tables.

OPTIONS
-A family
use the specified address family (eg `inet'; use `route --help'
for a full list).

-F operate on the kernel's FIB (Forwarding Information Base) rout-
ing table. This is the default.

-C operate on the kernel's routing cache.

-v select verbose operation.

-n show numerical addresses instead of trying to determine symbolic
host names. This is useful if you are trying to determine why
the route to your nameserver has vanished.

-e use netstat(8)-format for displaying the routing table. -ee
will generate a very long line with all parameters from the
routing table.

del delete a route.

add add a new route.

For a add or del;

Code:

route add default gw 192.168.0.1
route del default gw 192.168.0.1

Edit: I would suggest that you use the DNS provided by your ISP. You can add a third level as a fall back.

Code:

4.2.2.1        #Verizon third level DNS
4.2.2.2
4.2.2.3
4.2.2.4

Just ad these or at least one of them as another DNS in your '/etc/resolv.conf' file. Place them below other DNS if you want the top level DNS to be addressed first.

Please, forget about ifconfig and route, use iproute2(/sbin/ip). By the way it's syntax is much more handy.

You do as you wish but I will continue with route and ifconfig. I do use IP but most newbies don't. I'm comfortable with using the basic command sets with a newbie.

The syntax is not really handy but semantically easier once you use it and search through the reference(s).

Please post how you solved the problem so as to assist someone else who may search and find this thread.

n0p.cracker · 05-16-2008, 05:35 PM

first i have removed all what i had in route, and just added new one default gateway, here is the script

iwconfig wlan0 essid MICRO-PROCESS.BRIBIR;
iwconfig wlan0 channel 11;
iwconfig wlan0 key s:[my key];
ifconfig wlan0 netmask 255.255.255.0;
ifconfig wlan0 192.168.0.21;
ifconfig wlan0 up;
route add default gw 192.168.0.1;
